How are bacteria different from viruses ?

Answer:

economy

Explanation:

Whichever country do we look at, there is a strong relationship between the quantity of energy that the country uses and the size of its economy. The more developed and the larger the economy of a country is, the more energy is demanded for the economy to be driven. This leads to high demand for certain natural resources that produce energy, as the industry needs power in order to function. We can easily see this if we take in consideration the biggest economies in the world, USA, China, Japan, Germany, UK, France, and then if we see how much energy each of them uses, so we will come to a conclusion that the biggest economies are the biggest users of energy.

Answer:

I think its A. Drinking water.

Drinking water is example of maintaining homeostasis.

Explanation:

Homeostasis is the ability of a system to remain in equilibrium in terms of temperature or to maintain other physiological features. Since the sweating is responsible for cooling down the elevated body temperature hence drinking water can help in maintaining homeostasis. Homeostasis is a state where the proper functioning of body can take place. If the body is out of homeostasis or equilibrium then the function of the body will not be able to execute properly.

B. precipitation

Explanation:

Bogs refer to the wet and muddy ground that mostly consist of dead plants and mosses undergoing the process of decomposition. Bogs receives its water from precipitation. Various sources of precipitation are rain, snow, hail, sleet etc. So, unlike swamps and marshes, all these forms of precipitation impart water to bogs.

Answer:

tendons

Explanation:

A tendon attaches muscle to bone, transmitting the force from the muscle contraction to allow body movement.

The structure that attaches muscle to bone is called a tendon. Tendons are made of tough connective tissue and serve to transmit the force generated when a muscle contracts, allowing the movement of the skeleton. For a skeletal muscle to pull on a bone and create movement at a joint, it has specific attachment points; the origin is where the muscle attaches to the fixed (stabilized) bone, and the insertion is where the muscle connects to the bone that gets moved.

Answer:

The term that scientists use to describe the different forms of life on earth is biodiversity.

Explanation:

Biodiversity means biological diversity, a term that refers to the large number of species -among animals and plants- that exist on the planet. This diversity or variety is due, in principle, to the different genetic expressions that have resulted from evolutionary changes over time.

Biological diversity is a factor that defines the different ways in which an ecosystem can be presented and the interactions that can occur between living organisms.

The term Biodiversity is a compound word that comes from the words biology and diversity, first used in 1986 and recognized by the International Convention on Biological Diversity.

Answer:

C. Multi-celled eukaryotic organisms began to diversify

Explanation:

The Proterozoic is an eon in which numerous important things occurred. There were multiple organisms that appeared in this eon. They were able to perform the process of photosynthesis which resulted in gradual pilling up of oxygen into the atmosphere, thus changing the composition of the atmosphere, and setting up the terrain for the future development of other organisms. It is an eon though in which there were only single-celled organisms, while the diversification of multi-celled eukaryotic organisms occurred in the next eon, the Phanerozoic.

During the Proterozoic Eon, the increase in atmospheric oxygen from cyanobacterial photosynthesis led to the extinction of many anaerobic bacteria; thus, D ('anaerobic bacteria kept thriving with more oxygen') did not occur in the Proterozoic eon.

The Proterozoic Eon was a period of significant atmospheric changes, including the Great Oxygenation Event (GOE). This event was characterized by the rise in atmospheric oxygen due to the photosynthetic activity of cyanobacteria, which transformed Earth's anoxic atmosphere. This increase in oxygen led to drastic environmental changes and affected different organisms in various ways.

Answering the question, what did not occur in the Proterozoic eon, option D (anaerobic bacteria kept thriving with more oxygen) is incorrect. As the oxygen levels increased, many anaerobic bacteria were decimated because they could not survive in the presence of free oxygen. On the other hand, aerobic organisms thrived and evolved under these new oxygen-rich conditions.

Answer:

Nitrogen and Phosphorus

Explanation:

When the function of a whole ecosystem is limited because of a nutrient , which is present in limited amount, it is called as a limiting nutrient. The organisms uptake water and carbon directly from the environment as it is abundant in nature. The nutrients like nitrogen and phosphorous are present in limited amount and moreover they are not present in the form that can be directly taken up by the organism.

Thus, Nitrogen and Phosphorous are limiting nutrients.

Answer:

As heated material gets closer to the surface, it begins to cool

Explanation:

The core and surface have very different temperatures where the core is extremely hot as compared to the surface. When mantle gets heated as it passes near the core, it rises towards the surface. When it reaches the surface, it begins to cool and becomes more dense. The cooled magma then starts to sink down back near the core where it gets heated again and rises. This is what drives convection currents.

The Earth's plates move as a result of convection currents, with hot material rising towards the crust, cooling, becoming denser, and sinking back towards the core; a continuous cycle that drives plate tectonics.

The movement of Earth's plates is largely driven by convection currents within the Earth's mantle. Material near the core becomes heated and becomes less dense, causing it to rise towards the crust. This is reflected in the statement 'Heated materials become less dense, causing them to rise toward the surface'. Once this heated material gets closer to the surface, it begins to cool and becomes denser. This is referred to in the statement 'As heated material gets closer to the surface, it begins to cool'.

As it cools, the material becomes denser and sinks back towards the core, as referenced in the statement 'As materials cool, they become less dense and sink back toward the core'. This continuous cycle of heating, rising, cooling, and sinking causes the movement of Earth's plates.

Answer:

Most protists are unicellular. You may be wondering why those protists are not classified in the Archaebacteria or Eubacteria kingdoms. It is because, unlike bacteria, protists are complex cells.

Also:

Among these three main types of archaea are some subtypes, which include: Methanogens  — archaeans that produce methane gas as a waste product of their "digestion," or process of making energy. Halophiles  — those archaeans that live in salty environments.

Answer:

Archaebacteria are the prokaryotic anaerobic bacteria.

Explanation:

Archaebacteria are the prokaryotic bacteria. They live in an extremely harsh environment. They are different from the other bacteria with some characters like their habitat. Their cell wall don't have peptidoglycan like other bacteria. Archaebacteria are resistance to penicillin and some other antibiotics. These are of three groups such as methanogens, Halophiles, and thermoacidophiles.

Methanogens are methane-producing bacteria and used as fuel. Halophiles are found in saline water and heavy salt concentration. They contain red carotenoid pigment in the cell. So they appear red.  Thermoacidophiles can live in extremely high temperatures and high acidity.

asexual reproduction

genes

sexual reproduction

genetic diversity

protists

animals

plants

mammals

Answer:

In asexual reproduction, an organism inherits it's genetic material from a single parent. The new organism has the same genes as it's parent. In sexual reproduction, an organism inherits genetic material from two different parents. Sexual reproduction increases genetic diversity, whereas asexual reproduction does not. Plants, animals, and simple protists, can reproduce sexually or asexually. Mammals only reproduce sexually.

An element in Chemistry is a substance made up of only one type of atom, possessing a unique number of protons in its atomic nucleus. Elements are not limited to earth as they can be found throughout the universe.

In Chemistry, an element refers to a type of substance that is made up of only one type of atom, Therefore, the correct answer to your question is the second option: 'substances that are made up of only one type of atom'.

Explanation:

The soil is complex, composed of multiple layers/horizons all of which have different characteristic that make every horizon  to have its own special role in it. The horizon E is the third horizon from the top. This horizon is characterized by being mostly sandy, and because the water manages to go through it very easily it is a horizon in which there's heavy leaching going on. Because of the leaching, this horizon loses the clay, iron, and aluminium from it, thus they accumulate in the horizon below it. As a horizon it is very important, especially for the trees, as their root systems manage to develop very well in this horizon because it is loos and sandy.

The major function of the cell membrane is to provide a barrier around the cell, control substance movement via its selective permeability, and facilitate cell communication, making option B ('To receive and send messages between cells') the best answer. Hence the correct option is B.

The cell membrane's structure, primarily made of a phospholipid bilayer, allows it to be selectively permeable, controlling which substances can enter and leave the cell. It is involved in various functions including protecting and supporting the cell, and actively participating in the transport of materials. It also has the important role of facilitating communication and signal transduction, which means option B, 'To receive and send messages between cells,' best describes a major function of the cell membrane. It's also worth noting that the cell membrane encloses the cytoplasm and houses membrane proteins which may vary from one cell type to another, contributing to the diverse functions of the cell membrane in different cellular environments. However, while it does provide some support, option B is a more encompassing choice that includes this function as part of its role in cellular communication and interaction.
