Answer:
the last one sorry if i'm wrong
Explanation:
According to the passage from the Biology Department at University of California, Berkeley.Northern elephant seals have reduced genetic variation because hunting by humans reduced their population size to as few as 20 individuals at the end of the 19th century. Their population has since rebounded to over 30,000, but their genes still carry the marks of this near extinction: they have much less genetic variation than a population of southern elephant seals that was not hunted as intensely.
The best option that describes is" the population has not evolved because there was no change in allele frequencies.Thus, option B is correct.
What is population?The term population reffered to the total number of people living in a particular given area.The population of an organism can't survive if it exceeds it's carrying capacity.
The causes that affect population growth animals that if there are more plants than usual in area, populations of animals that eat that plant may increase.
If animal population increases the population that eat that animal might also increase.
The effects of animals population can be dangerous and when population exceed the carrying capacity of their environment, animal suffer of malnutrition and disease.
When predictors became scarce due to over population, the weekar species of animal start or die in other ways .
The accurate description of the growth of a natural animal population is limited by environmental factors.
Therefore,The best option that describes is" the population has not evolved because there was no change in allele frequencies.Thus, option B is correct.

Population Growth
Project: Analyzing Factors That Affect Carrying Capacity and Biodiversity
In this assignment, you will use simulations to analyze how climate, resources, and habitat size affect
carrying capacity. You will then look at another simulation to analyze the effects of certain factors that
affect biodiversity and populations. Finally, you will write and revise a conclusion on how human activity
affects biodiversity.
Background Information
Population growth is the change in size of a group of organisms of the same species over time. It is
affected by four factors: birth rate, death rate, immigration, and emigration.
Carrying capacity is the maximum total population that an area can support. Carrying capacity limits
population growth and is affected by competition for food, water, shelter, or mates, and threat of
predators, disease, and parasites. Carrying capacity may be affected by one or a combination of these
factors.
Biodiversity is the total variety of organisms that live in the biosphere. Biodiversity is affected by the loss
of habitat, introduction of invasive species, pollution, and/or human activities.
Answer:
Question 1: How does increasing the size of the habitat affect carrying capacity? Explain your answer. Recall the scenarios: 0–15 years, Little land; 15–30 years, Moderate land; 30–45 years, Ample land.
Population numbers self-regulate to some extent since mortality rise when a population exceeds its carrying capacity. Carrying capacity is affected by disease, competition, predator-prey interactions, resource usage, and the number of populations in an ecosystem.
Explanation:
Question 2: How and why did changes in the environmental conditions affect carrying capacity in this scenario? Recall the scenarios: 0–15 years, Harsh winter; 15–30 years, Harsh winter and Cold spring; 30–45 years, Harsh winter, Cold spring, and Hot summer.
The carrying capacity of an environment is also affected by conditions within or adjacent to it. If the environment is adjacent to a human population, for example, this may have an impact on its carrying capacity. Pollution can also have an impact on the carrying capacity of an environment.
Question 3: If there were no other changes in the habitat, would the value under “Larger Than Ample” be correct? Why or why not
Climate change isn't only about global warming. While it is true that temperatures would rise during the summer months, it is also feasible that the winter months would be even colder. As a result of this effect, the winters will be exceptionally cold from year 0 to 15.
Question 4: Suppose there were changes in the habitat that caused this actual value. What might a combination of those changes be
Assume that the climate in a habitat shifts. The amount of precipitation reduces by 20% over time. It will have an impact on the habitat because species that have adapted to drier climates will supplant those that are less suited to the new climate. This best circumstance explains the cause for adaptation, and those that adapted rapidly will replace those who found it difficult to adapt, resulting in the extinction of species as those who can thrive will be able to cope with the rapid shift in the environment. The most fittest survive in the new environment, according to Charle's Darwin thesis.
Question 5: How would you describe the effect of a 1°C increase of temperature on the biodiversity of the habitat in terms of number of populations and number of individuals in the populations? Use evidence from your graph and table to support your answer
The graph and table in the supplied question were not provided, nor could they be found anywhere, hence the question was answered based on prior knowledge. Earth's species can adapt to their surroundings, however adaptation in organisms can take thousands to tens of thousands of years. However, for the last 200 years, a consistent rise in temperature has been recorded.
The thermal limits of species residing in the tropics, equator, and poles have already been altered. If the global average temperature rises by one degree Celsius, the number of people on the globe will drop. The population of a species will decline as the number of individuals decreases.

For example, plasma membrane proteins carry out functions as diverse as ferrying nutrients across the plasma membrane, receiving chemical signals from outside the cell, translating chemical signals into intracellular action, and sometimes anchoring the cell in a particular location.
Answer:
All cells have plasma membranes. Can molecules enter and leave the cell? Yes. The plasma membrane (also called the cell membrane), is a lipid barrier where molecule organelles live. The golgi ( a cell organelle) helps move the proteins across the plasma membarane. Proteins cannot move through the plasma membrane barrier by themselves because they are not small enough like water.

Electromagnetism
Strong
Gravity
Mass
Answer:
Mass
Explanation:
From walking on the street, to launching a rocket into space, to sticking a magnet on your refrigerator, physical forces are acting all around us. But all the forces that we experience every day (and many that we don't realize we experience every day) can be whittled down to just four fundamental forces:
Gravity.
The weak force.
Electromagnetism.
The strong force.
These are called the four fundamental forces of nature, and they govern everything that happens in the universe.

Why is the classification species not considered a group
Answer:
All living organisms are classified into groups based on very basic, shared characteristics. Organisms within each group are then further divided into smaller groups.
There are five kingdoms: • Animals • Plants • Fungus • Protist • Bacteria Scientists classify animals together because they have similar characteristics such as they eat other living things and have many cells. As you can see from the chart, kingdoms are divided into groups called phyla.
hope it helps ya mate.
hoping to have a brainliest.
The classification of species is not considered a group because each species is a separate type of organism. The correct option is D.
What are groups and species?Group is the level of taxonomy in which the organism is present, which has someone's character. Like in the insect group, all insects are present.
Species are the largest level of the taxonomy of the organism. Species are animals or plants or individuals that have the same characteristics and those that can mate with each other and form fertile offspring.
Groups contain numerous species. Like in insects, the insects contain numerous insects that are very different from each other. Like, bees and beetles are very different from each other.
Thus, the correct option is D. Each species is a separate type of organism.

Why are shadows longer in the morning and evening?
Make sure you give a full, detailed answer, not just one sentence.
Answer:
Shadows are longest in the early morning and late afternoon/early evening when the sun appears low in the sky. As the Earth rotates on its axis, the sun hits each location in the morning at an angle. ... As Earth continues to spin toward sunset, the increasing angle causes shadows to lengthen!
