Answer:
Environmental change
Explanation:
A species that has little genetic variation cannot evolve (change) in response to variable environmental conditions because genetic variation is the raw material on which natural selection operates to select individuals. Adaptation to changing environmental conditions only can occur when there is variation (either genetic or phenotypic variation). In consequence, a species with low genetic variation is at a high risk of extinction, especially in challenging environments.

What phenotypic results for each environment would you predict if starting with the following population sizes?
1000:
100:
10:
Explanation:
populations are large, it seems fair to ask whether genetic drift is really all that important. It's true that most populations are large, but they don't necessary act large. Thus, the rate of genetic drift is not really proportional to census population size (Nc). Rather, it's proportional to something more abstract — specifically, the effective population size (Ne). In an ideal population of sexually reproducing individuals , Ne will equal Nc. An "ideal" population has the following characteristics, and most deviations will decrease the effective population size:
There are equal numbers of males and females, all of whom are able to reproduce.
All individuals are equally likely to produce offspring, and the number of offspring that each produces varies no more than expected by chance.
Mating is random.
The number of breeding individuals is constant from one generation to the next.
Essentially, anything that increases the variance among individuals in reproductive success (above sampling variance) will reduce Ne (the size of an ideal population that experiences genetic drift at the rate of the population in question). For example, consider the effect of unequal numbers of mating males and females. In an ideal population, all males and all females would have an equal chance of mating. However, in situations in which one sex outnumbers the other, an individual's chance to mate is now affected by its sex, even if all individuals within each sex have an equal chance to mate. In this situation, effective population size can be predicted by the formula Ne = 4NmNf/(Nm + Nf), where Nm is the number of males and Nf is the number of females. Figure 4 shows the relationship between Ne and Nf in a population of 1,000 mating individuals. In an ideal population, all individuals have an equal opportunity to pass on their genes. In real life, however, this is rarely the case, and Ne is particularly sensitive to unequal numbers of males and females in the population.follow me bye nice study

The agricultural biotech company you work for has tasked you and your co-worker to genetically engineer a plant that produces more oxygen that at the same time also produces more sugar. Your co-worker states that this is impossible.
Questions: Based on what you've learned how would you respond to your co-worker?
What is your opinion of the ethics of manipulating crop plants in such a way?
Answer:
- The co-worker is wrong, it is indeed possible
- Genetically engineered plants may represent a milestone to alleviate hunger in the world
Explanation:
During photosynthesis, plants use carbon dioxide (CO2) from the air and water (H2O) from soil and rain in order to produce oxygen and glucose, which is a sugar (molecular formula C6H12O6). Subsequently, plants release oxygen into the air and store energy (and carbon compounds) in the form of glucose. In consequence, an increase in the photosynthetic rate is directly associated with an increase in both the production of oxygen and glucose. On the other hand, genetically engineered plants can help to reduce hunger in developing countries. In consequence, it is acceptable to develop genetically modified plants as long as contemplating regulatory measures aimed at producing safe products (for example, by avoiding the introduction of genetically engineered genes into wild crop populations).

Explain why the Northern Hemisphere it’s warmer in the summer than in the winter
Answer:
It is because of the axis it is on!
Explanation:
In fact, in the Northern Hemisphere, the orbit of the earth takes us further from the sun in summer. Summer is hotter than winter due to the tilt in the axis of the earth of 23 degrees. ... – the sun is higher in the sky, meaning more sunlight shines on the earth more directly.

A. The mountain has less variety in the environment.
B. The mountain would cause less fragmentation.
C. The mountain has wider range of environments.
D. The mountain has more resources.
Answer:
C. The mountain has wider range of environments.
Explanation:

What is Grassland habitat?There are various locations and climates on earth where grassland environments can be found. Depending on where in the world they are and the type of climate there, they may also be referred to as prairies, savannahs, steppes, or pampas.
Because there are few places for animals to hide from predators in grasslands, they have developed underground burrows or grown tall enough to look over thick grasses and shrubs.
Many grasslands have been used for farming because they are suitable for raising crops and providing food for cattle. Yet, this means that grassland animals can no longer reside there.
Therefore, Steep mountain habitat have a higher rate of speciation than a large, open grasslands habitat The mountain has wider range of environments.

If a plant were unable to produce root caps, what would be the effect on plant function?
O The plant would have enlarged root cells.
The plant would have damaged root cells.
O The plant would not be able to grow to normal height.
O The plant would not be able to absorb water from the soil.
Answer:
The plant would not be able to grow to normal height.
Explanation:
If a plant does not develop a root cap, the plant does not allow the root to grow downwards.
Hope this helps :)
If a plant is unable to produce root caps, the plant will be unable to absorb water from the soil; this is the final option, as root caps are a specialized protective layer at the tip of plant roots that help protect the plants.
What is the significance of the root cap in the plants?The root cap contains cells that are capable of secreting slime, which helps the root to move easily through the soil, helps to maintain the proper orientation of the root tip so it can efficiently absorb water and nutrients from the soil, and acts as a barrier that protects the delicate root tip cells as the root grows through the soil.
Hence, if a plant is unable to produce root caps, the plant will be unable to absorb water from the soil; this is the final option, as root caps are a specialized protective layer at the tip of plant roots that help protect the plants.

Heat energy is released from the body to the surroundings.
Heat energy is taken from the surroundings to the body.
Chemical energy is converted to mechanical energy that’s used for muscle movements.
Radiant energy is converted to mechanical energy that’s used for muscle movements.
Heat energy is converted to mechanical energy that’s used for muscle movements.
Answer: Chemical energy is converted to mechanical energy that’s used for muscle movements.
Heat energy is converted to mechanical energy that’s used for muscle movements.
Explanation:
According to the I law of thermodynamics, energy can neither be created cannot be destroyed but it can only change its form. In the given situation, the energy can only be conserved when it is not lost to the environment. The chemical energy is produced in the body in the form of ATP which is converted into mechanical energy to allow the movement of the muscles during running. So, chemical energy is converted into mechanical energy by this way. The heat energy when directly converted into mechanical energy to induce the movement of muscles the energy will remain conserved and will not lost to the environment.

In the ELISA procedure, first a protein sample is immobilized to a plastic well. Then, the antibody to the protein of interest is added, incubated, and the excess is washed out. Next, the detection antibody (which binds to the primary antibody) is added, incubated, and the excess is washed out. The last step is to add the detection dye (which binds to the detection antibody) to the wells and allow it to incubate. What do you predict the result would look like if you added the detection antibody first, then the antibody to the protein of interest
Answer:
In this ELISA procedure, a sample of protein is immobilized in the plastic well and then antibody for this protein added and incubated, and cleared out. In the given setting detection, the antibody is conjugated with the protein of interest and if the substrate molecule added to the reaction it will produce a colored product by reacting with the enzyme.
No reaction will take place in the well in case of not adding secondary antibody or detection antibody to the reaction and no colored product will be received.

What are some causes of CO2 levels being higher in some areas than others?
Answer:
human activities for example the burning of fossil fuels in cars or the clearing of forests for agriculture or development
In some areas, human activity is high for burning fossil fuels so these areas create more carbon dioxide.
What are the causes of CO₂ levels?Growing concentrations as a result of human activities including burning fossil fuels in vehicles and power plants, and industrial operations.
Destroying forests for development or cultivation may increase carbon dioxide levels because plants consume CO₂ in photosynthesis and during respiration CO₂ released into the atmosphere.
Plants absorb more carbon dioxide via photosynthesis than they emit through respiration throughout the day or in the spring and summer, the amount of carbon dioxide in the air decreases.
Therefore human activities produce more CO₂ by burning fossil fuels some area level is high than others.

Explanation:
Scientists analyzed data collected over a period of years in a game reserve in South Africa to test the hypothesis that competition with lions limits the abundance of leopards in the same community. The game reserve encompasses a variety of habitats, from open grassland to wooded areas around rivers and streams. It contains most of the indigenous mammal species and an adequate availability of their prey. For the most part, the leopards and lions show similar habitat preferences in the reserve.
The mass of the average lion is about three times that of the average leopard. The scientists analyzed several factors that might influence the abundance of each population, including the sizes of the animals preyed on by each species
Size of Prey Animal Percent of Leopards’ Prey (±2SEx¯) Percent of Lions’ Prey (±2SEx¯)
Small 34 ± 2 3 ± 1
Medium 63 ± 3 23 ± 2
Large 3 ± 1 36 ± 4
Very large 0 38 ± 3
Because competition with lions might affect the population size of the leopards, the scientists also analyzed data on the lion and leopard population sizes in the game reserve (Figure 1).

Answer:
The correct answer would be - these are the ecological community that shows the interspecific competition.
Explanation:
In this ecological community, both predators lion and leopards are living together and by the given data and information it is evident that they both share the same habitat and they both depend on the same prey for their food.
This cause competition between both lion and leopard for food and habitat. Such competition or interaction is referred to as the interspecific competitions negatively impacted by the presence of the other because they will have less food.
