A researcher is creating pedigrees for a trait he suspects to be dominant in humans. what are some of the likely features of his pedigrees for families with this trait?

Answer:

Hydrosphere

Explanation:

All the glacial ice present on earth belongs to the hydrosphere. Hydrosphere represents all the water bodies (ice, vapor, and liquid) existing on earth.

Glaciers are the region where the temperature is low and continuous accumulation of snow takes place in consecutive years. In due course of time, these accumulated snow undergoes compaction as a result of which it subsequently forms ice.

The factors that are responsible for the formation of snow re s follows-

1) Areas of high latitude

2) Low temperature

3) Presence of abundant snow

4) Snow accumulation must be more.

Answer: Recliners; Decline

Explanation:

If a person spends most of time leaning back on the recliners then the physical fitness of the person will decline.

Leaning back for a longer duration of time decreases the health of spines, as it may lead to pain in back.

Physical fitness needs to be maintained by proper workout and exercise, taking breaks in between if maintaining a constant postures for longer duration of time.

The correct answer is A.

hope this helps :D

Answer:

The correct answer is D. Both replicate genetic material

Explanation:

Mitosis is the process when an animal cell, plant cell, et cetera divides into two (or replicates itself).

Binary fission is the process when a bacteria splits off into two, which is a simple process since bacteria don't have a nucleus.

They both replicate genetic material when dividing or splitting into two,

so the correct answer is D. Both replicate genetic material.

5 CENTIMETERS is too big foe an ant. It would be A. Lizard

Answer:

Meiosis

Explanation:

Mitosis results in daughter cells with the same genetic component as the parent. Hence, a drastic change in the environment may wipe out the entire population of organisms that only reproduce by mitosis.

Meiosis results in daughter cells whose genetic components are different from one another and that of their parents. Crossing over and recombination ensures that meiosis increases the genetic variability of a population.

Hence, difference in genetic composition of organisms in a population might help in the survival of some members of the population in case of adverse environmental changes.

The correct answer for fill in the blanks is Albedo

The term albedo defines the proportion of radiation or incident ray that is reflected back by the surface. Earth has an albedo of about 30% reflecting back into the space. The rest 70% is absorbed by the earth. The values for albedo is changing as compared to last ice age. It is due the effect of human activities such as global warming, deforestation, pollution, etc.

Scientists describe the Alaskan King crab if a fishery is currently removing crabs from the ocean faster than they can reproduce as potentially renewable. Therefore, the correct statement is option B.

Renewable resources are resources which can be replenished naturally over time, such as solar or wind energy, while nonrenewable resources are those that cannot be replaced once they are used up, such as oil or coal.

If a fishery is removing Alaskan King crabs from the ocean at a rate faster than they can reproduce, there are high chances that the population can be depleted faster and cannot be naturally replenish itself. The population of Alaskan King crabs will not be able to recover if this situation continues and will be considered nonrenewable after a certain point.

However, certain measures should be taken for regulating the fishing industry. This will be the only way to ensure that the population has time to recover, and the Alaskan King crab population can potentially renewable itself to support sustainable harvesting practices.

Alaskan King crab can be described as potentially renewable, if measures are taken to regulate the fishing industry and management practices are implemented to ensure sustainable harvesting as the crab population has the potential to recover itself.  

Therefore, if a fishery is currently removing crabs from the ocean faster than the Alaskan King crab can reproduce, the population will be considered as potentially renewable.

The dendrites are the structures on a neuron that receive messages from other neurons.

The part of the neuron that receives messages from other neurons is called the dendrite. Dendrites are tree-like structures extending away from the neuron's cell body. Their primary function is to receive electrical signals at specialized junctions known as synapses, where contact is made with the axon terminals of other neurons. With their branched form, dendrites increase the surface area for receiving these signals, sometimes connecting a single neuron to thousands of others, facilitating complex neural communication.

A buffer zone around large commercial farms is intended to protect surface waters from the harmful effects of fertilizer runoff by intercepting pollutants before they reach water bodies and contribute to eutrophication and 'dead zones'.

Jon is campaigning for the introduction of buffer zones around the large commercial farms in his community to manage the effects of chemical fertilizers. A buffer zone will most effectively protect surface waters from fertilizer runoff. Buffer zones are areas of land maintained in permanent vegetation located between cultivated fields and water bodies, designed to intercept pollutants, soil, and agricultural runoff, containing nitrogen and phosphorus, before they enter water systems. Without such zones, excessive nutrient loads from fertilizer runoff can lead to the eutrophication of water bodies, resulting in an overgrowth of algae that can create 'dead zones' by depleting dissolved oxygen and harming aquatic life. The correct answer to the question is (d) protect surface waters from fertilizer runoff.

A buffer zone around large commercial farms can help manage the effects of chemical fertilizers by d) protecting surface waters from fertilizer runoff. When fertilizer is applied to farmland, it can be carried away by rainwater or irrigation and enter nearby bodies of water, causing eutrophication and dead zones. A buffer zone acts as a barrier, absorbing and filtering nutrients from the runoff before they reach surface waters.

Final answer:

The correct answer is option d. differential reproduction. The scenario where white rabbits are more visible to predators and thus have a lower survival rate compared to brown rabbits is an example of differential reproduction, a key mechanism of evolution. Genetic drift and diversifying selection are other concepts relevant to changes in population genetics but are distinct from the selective pressure leading to differential reproduction.

Explanation:

The scenario described in the question, where white rabbits are more easily seen by predators than brown rabbits, leading to white rabbits having a lower survival rate and a lower chance to reproduce, is an example of differential reproduction. Differential reproduction is a key mechanism of evolution, where individuals with traits that are better suited to their environment tend to survive and reproduce more than those with less favorable traits. As a result, the traits that enhance survival and reproduction become more common in the population over time.

Genetic drift can also play a role in changing allele frequencies in a population, but it is a random process that is not directly related to a trait's influence on an organism's ability to survive and reproduce. Genetic drift can occur due to random sampling effects, such as when a few individuals colonize a new area (founder effect) or when a population size is drastically reduced (bottleneck effect), leading to a random shift in allele frequencies.

When a victim with a foreign-body airway obstruction becomes unresponsive, begin CPR starting with chest compressions and then call emergency services.

In the case where a victim with a foreign-body airway obstruction becomes unresponsive, the first course of action that should be taken is to initiate the Cardiopulmonary Resuscitation (CPR) process, starting with chest compressions. The chest compressions can help to remove the obstruction and also start the circulation of blood that could have been discontinued as a result of the obstruction. Follow the standard process for CPR: Compressions, Airway, Breathing (CAB). This should be followed by calling emergency services immediately.

The correct statement is A.) As the human population grows, and fishing technology increases, fish population stocks decline, due to unsustainable fishing practices and overharvesting.

The relationship between the human population, technology, and fish population stocks is one where increased human population and advancements in fishing technology have led to a decline in fish populations. As the demand for fish has grown with the human population, fishing methods have become more efficient with the advent of diesel technology and mathematical ecology. Unfortunately, these advancements have not always been used sustainably, leading to overharvesting and subsequent declines in fish populations. Sustainability in this context means fishing at rates that do not exceed the population's ability to reproduce and maintain healthy population sizes.

Historically, during the age of sailing, fishing efforts had low impact on the environment, allowing fisheries to operate within their carrying capacities. Transitioning to modern times with diesel-powered vessels and advanced fishing techniques, the human capacity to fish has greatly increased. Despite these technological advances, the pressure on fish populations has continued to grow, leading to overfishing and a decline in marine biodiversity, as fish populations are unable to rebound quickly enough to meet intense fishing pressures.

To summarize, the correct statement that describes the relationship between human population growth, technological advancements, and fish stock populations is: A.) As the human population grows, and fishing technology increases, fish population stocks decline. This is due to overharvesting, habitat destruction, and unsustainable fishing practices that have grown alongside human population and technological capabilities.
