Brendan made a chart to categorize the characteristics of animals. which phrase should be written in the column titled “sometimes”?

A. are multicellular

B. have membrane-bound organelles

C. produce their own food

D. display an asymmetrical body plan

it’s cells reproduce and die at the same rate

Answer: Option B

Explanation: When the organism has stopped growing then there is no visible growth in the body of the organism.

When the cells proliferate and dies at the same rate, the change is zero and the body seems to be finished growing. This can be described on the cellular basis that the number of cells remains constant as the rate of proliferation and death is same.

Anaerobic respiration makes a total of 2 ATP. Aerobic respiration is much more efficient and can produce up to 38 ATP with a single molecule of glucose.

A genotype is the set of genes in our DNA which is responsible for a particular trait. And a phenotype is the physical expression, or characteristics, of that trait. Like for example, two organisms that have even the minutest difference in their genes are said to have different genotypes.

Hope this helps:)

Phenotype is the term used to describe the morphological, physiological and behavioral characteristics of the individual that we can visualize and that arise through the interaction between the genotype and the environment. The phenotype can be motivated in some situations. For example, let's say your parents have black hair, and you have inherited this characteristic from them. This characteristic is something that we can visualize, that is, it is the phenotype. However, you can change the color of your hair, or your hair may appear lighter due to the action of the sun and the chlorine of the picina.

The genotype, on the other hand, is the term used to describe your genetic makeup based on the genes you have inherited from your country. For example, we can say that your father has black skin represented by the "AA" genes, however your mother has a white skin represented by the "aa" genes, you received a gene from your mother and one from your father, with the genetic makeup (genotype) the "Aa" alleles and the black skin phenotype.

When a bird population is divided by a natural disaster like a tornado, habitat isolation and different environmental pressures lead to divergent evolution through natural selection, possibly resulting in speciation over time.

After a tornado, a population of birds is separated into two very different habitats. As a result of habitat isolation and differing environmental pressures, the process of natural selection will likely lead to divergence in the two bird populations. Each group of birds will adapt to the specific conditions of their new environment, resulting in evolutionary changes that may ultimately lead to the formation of new species over long periods of time.

In a bird population forced into a new habitat after a natural disaster, like a hurricane on the Mississippi Gulf Coast, individuals with traits better suited to the new conditions will have higher survival and reproductive rates. Over successive generations, these advantageous traits become more common. This selective pressure could lead to noticeable differences between the now-separated populations in behavior, physical characteristics, and even their genetic makeup.

An example of this can be seen during periods of drought, where food availability changes. Birds with larger and broader beaks may be better suited to consume large seeds with hard shells, which become more common during droughts. If these conditions persist, the population's characteristics may shift towards these advantageous traits guided by natural selection.

Biomass has it's advantages and disadvantages. Biomass is a type of fuel that is not a limited substance, while coal is very limited. While this may be true, biomass in some ways is more expensive than coal. It also causes the same amount, or more, air pollution. Biomass as well does not create as much fuel when it's burnt in terms of carbon dioxide.

Because it can be created from sources that are renewable and can be continuously replenished, such as garbage and plants, bioenergy, also known as energy obtained from biomass, is a sustainable substitute for fossil fuels.

Organic material, including plants, trees, and garbage from the agricultural and urban sectors, is the source of biomass.

It can be used as a fuel for transportation as well as for heating. By using biomass more frequently, the EU can diversify its energy sources, spur economic expansion and job development, and reduce greenhouse gas emissions.

All kinds of wood debris can be used in a wide range of biomass technologies and generate great biomass fuels.

Bioenergy, also known as energy from biomass, is a sustainable alternative to fossil fuels since it can be produced from renewable and perpetually replenishable sources like trash and plants.

Thus, it can be concluded that biomass is a better alternative to coal.

Explanation:

I dont see anything.

The correct order of the processes of respiration starts with pulmonary ventilation, followed by external respiration, then inter-pulmonary respiration, and ending with internal respiration.

The processes of respiration should be in the following order:

pulmonary ventilation

,

external respiration

,

inter-pulmonary respiration

, and then

internal respiration

Pulmonary ventilation is the first step in the respiratory process where the air is moved into and out of the lungs. External respiration is the exchange of gases with the external environment and it occurs in the lungs. Interpulmonary respiration refers to the transportation of gases between the lungs and the cells of the body, this is conducted by the circulatory system. Finally, internal respiration is the process in which oxygen is used for the metabolic reactions in cells and carbon dioxide, as a byproduct, is produced.

Charles Darwin:

Charles Darwin was an English biologist, naturalist and others. He contributed to science in many different way, but he's most regarded for his evolution theory which can be found in his famous book, On the Origin of Species.

Evolution, Darwinism:

When he first published his book many people thought he was crazy and that his theory was a total blasphemy, and they even created what we would now call a meme, as we can see in the first image. Turns out, the book was published in  1859, which meant he had enough evidence to prove his theory due to the fact that in 1831 he did his famous voyage in the HMS Beagle to the Galapagos, where he studied different species of finches.

But, going deeper in to the theory, he suggested that animals developed in tiny steps as natural selection went causing modifications to their genes so that they could be more competitive in their environment. That was also part of his proposal to how new species originated - at one point, so many changes would have occurred that the product of natural selection would be a total new species.

A visual way of representing his theory would be with the famous "monkey-scale" where we can see how our upright and non-hairy appearance originated, as we can see in the second image.

uniformitarinism

Explanation:

There were several theories associated with evolution. In the theory, evolution was defined as the biological change process that has decedents originate from different ancestors.

Uniformitarinism is the prevailing theory of evolution. It focuses on the formation of the rocks and the earth as we know it today

Gradualism focuses on the gradual change over a long time.

Catastrophism focuses on the catastrophic formation of matter from a mass of matter.

Three ideas about geologic change are Plate Tectonics, Weathering and Erosion, and Climate Change.

1. Plate Tectonics: Plate tectonics is a widely accepted scientific theory that explains how the Earth's lithosphere (the rigid outer layer) is divided into several large plates that move and interact with each other.

These plates can collide, separate, or slide past each other, causing various geological phenomena.

2. Weathering and Erosion: Weathering and erosion are processes that contribute to the transformation and transportation of rocks and landforms.

Weathering refers to the breakdown and alteration of rocks at or near the Earth's surface due to physical, chemical, and biological processes. It includes processes like freeze-thaw cycles, chemical reactions, and the actions of plants and animals.

3. Climate Change: Climate change refers to long-term shifts and variations in global or regional climate patterns. It is driven by various factors, including natural processes and human activities.

Geological evidence, such as ice cores, sediment layers, and fossil records, provide insights into past climate changes that have occurred over millions of years.

The answer is C To eat producers and produce energy

Answer:

C. To eat producers and produce energy.

Explanation:

In a food chain, a series of organisms are linked to together in a process whereby one eats the other and provides energy at each trophic level.

Every food chain typically starts with the producers who obtain the energy either through the sun or chemicals and make their own food,

The organisms who eat the producers are known as primary consumers and they are the ones who provide energy to the next trophic level of the secondary consumers .

The food chain is as follows:

Producer (plant) ---> primary consumer (herbivore)---> secondary consumer (carnivore)- --> tertiary consumer

The age pyramid with the largest base of pre-reproductive population is typically observed in countries with rapid population growth.

The age pyramid with the largest base of pre-reproductive population is typically observed in countries with rapid population growth, particularly in underdeveloped countries where individuals do not live to old age due to less-than-optimal living conditions. These countries often have a pyramidal age structure diagram, indicating a preponderance of younger individuals, many of whom are of reproductive age or will be soon.

#SPJ12

The age pyramid of economically underdeveloped countries tends to exhibit the largest base of pre-reproductive population. This comes from a high birth rate, but also a lower life expectancy. In contrast, developed countries usually have a smaller pre-reproductive population due to lower birth rates and higher life expectancies.

The age pyramid that has the largest base of pre-reproductive population is typically observed in economically underdeveloped countries. Age structure diagrams for these populations often have a pyramidal shape, indicative of a large young and pre-reproductive population. However, fewer of these individuals reach old age because of poor living conditions. For instance, in many parts of Africa and Asia where economic development is lower, there's a large preponderance of younger individuals (Figure 36.17).

On the contrary, developed countries like the United States and Italy exhibit a different age structure. These populations have a flatter structure or even a 'bulging' pyramid shape due to lower birth rates and higher life expectancy. Therefore, there's a lesser percentage of their population in the pre-reproductive age group (Figures 13.7 and 20.5).

Increased use of nuclear energy is increased power sources to other places.

the answer is A. because the roads are black and take in more light which makes the area hotter

Answer:

The correct answer is option A, that is, urban areas absorb more of the Sun’s radiation.

Explanation:

The cause for the urban regions exhibiting a warmer climate in comparison to the mountainous regions is the maximum captivation of the radiation of the Sun by these regions. This is termed as the urban heat island effect. This results in the air to be warmer in comparison to the other regions.  

There are various causes related to the elevation in the temperature. One of the causes is exhibiting a huge number of roads and buildings in the urban regions. This takes part in the captivation of the heat from the Sun. Another cause is the absence of green plants, which absorbs the heat and the cools the surrounding.  

The Sun's affect on global warming can mostly be attributed to variations in the near-infrared and visible wavelengths of solar radiation. As previously stated, these types of radiation are absorbed by the lower atmosphere, the oceans, and the land

Final answer:

Solar radiation is absorbed by Earth's surface, causing warming, while some is reflected back into space. It affects the ionosphere by altering its height due to ionization and can disrupt satellites. Additionally, it plays a key role in the greenhouse effect and Earth's radiation balance.

Explanation:

The effect of solar radiation on Earth is extensive, influencing numerous aspects of the environment. When radiation from the sun reaches Earth, it is mostly absorbed by the Earth's surface, which warms our planet. However, some of this energy is reflected back into space by the surface and atmosphere.

Radiation also impacts the ionosphere, a layer high in Earth's atmosphere. The ionosphere's boundary fluctuates between approximately 60 kilometers during the day to about 85 kilometers at night due to the sun's ionization effects. Solar radiation, which includes X-rays and gamma rays, creates ionization levels similar to those during the daytime, and it can even prompt sensitive satellites to shut down their electronics to protect against damage.

Most solar radiation falls within the visible spectrum, but ultraviolet radiation is also significant as it is absorbed on its way to Earth's surface, lessening UV levels experienced on the ground. The Earth emits radiation too, but in longer, infrared wavelengths which are associated with the greenhouse effect. Greenhouse gases absorb this infrared radiation and re-emit it, causing warming of the Earth's surface and lower atmosphere.

The radiation balance of the Earth is critical; the planet must emit as much energy as it absorbs to maintain a stable temperature. When greenhouse gases absorb and re-emit radiation, they contribute to this dynamic balance but also cause global temperatures to rise under certain conditions.

Explanation:

The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges. The brain is also cushioned and protected by cerebrospinal fluid.

Answer:

Paleozoic

Explanation:

It is during the late Paleozoic era, in the Carboniferous and Permian Periods, approximately 300 million years ago, that this transition occurred. During this period, there were higher global temperatures and tropical swamps dominated land on the Earth. This allowed amphibians to move farther inland.  Later, synapsids and diapsids now dominated the land.

During the Paleozoic era, life began transitioning from the oceans to land. This era was a time of significant evolutionary change, with the emergence of plants and many types of animals onto the terrestrial landscape. So the correct answer to the multiple-choice question is Paleozoic.

The Paleozoic era, which is a part of the Phanerozoic Eon, extended from about 541 million to 252 million years ago and is known for the proliferation of life. Within this era, there was a great diversification of life forms, specifically during the Cambrian period where we see the 'Cambrian explosion' of diverse multicellular organisms. Moreover, it is during the later periods of the Paleozoic era that we observe life-first ventures onto land—evidenced by the earliest land plants and animals like amphibians and insects. Sedimentation, tectonics, and evolutionary evidence found in the fossil records all support this crucial transition period. The Mesozoic and Cenozoic eras followed the Paleozoic, with the Mesozoic known for the era of dinosaurs, and the Cenozoic characterized by mammalian evolution and the rise of modern ecosystems.

I’m pretty sure the correct answer would be A.

Based on option A the transition is just more trees, which gives out more oxygen. B having a massive volcanic eruption can cause certian things to die off and could eventually kill off certian species and forms of air. Example would be killing of the trees. C oil spill in the bay can cause damage by pollution and dieing of species. D acres- wide forest fire. Again that would take away oxygen supply and take away natural habbitates of animals/species. There for the answer would be A.

Answer: Oceans

Explanation:

Climate is primarily determined by the interaction between air and ocean. The warm wind circulate and makes the temperature feasible for life.

Oceans heat the air above it and it circulates from the equator region to the polar region to make the temperature optimum. The circulation of air due to ocean leads to climate change.
