This means the dolphin is an vertebrate.
Answer:
Dolphins having gill pouches would mean that dolphin embryos go through a fish phase during development. Dolphins are closely related so dolphins should go through a fish phase.
Explanation:
B. less nutrients in the water
C. higher water temperatures
D. fewer nitrates
More aquatic life is shown in coastal area if there is increased upwelling in a coastal area. Thus, option A is correct.
Upwelling is an oceanographic process that contains wind-driven motion of dense, cooler and usually nutrient-rich water from deep water towards the ocean surface. It replaces the surface water of ocean or nutrients deficient water form the surface.
The increased availability of nutrients in upwelling region or surface of ocean region it's very usually for aquatic animals due to presence of nutrients.It increase the production of fish.
Approximately 25% of the total global fish catches come from five upwelling, and the area of upwelling is very little as compared to other area i.e there is only 5% of the total ocean is upwelling and is is driven by coastal current.
Therefore, we can say that upwelling in a coastal area increase the population of aquatic life. Thus, option A is correct.

Natural Selection and Evolution Not all members of a species are the same. Every species exhibits this is due to variation and not all individuals in a population will survive to reproduce due to different traits.
The two evidences that supports the fact that species change due to certain genetic variations are that mutation and natural selection both cause changes in a population.
Natural selection has been defined as the postulation by Charles Darwin that organisms that are more adapted to their environment live longer and reproduce hence pass on their favorable traits to their offspring.
The two evidences that supports the fact that species change due to certain genetic variations are that mutation and natural selection both cause changes in a population.
Therefore, Natural Selection and Evolution Not all members of a species are the same. Every species exhibits this is due to variation and not all individuals in a population will survive to reproduce due to different traits.

Answer:
Explanation:
carrying capacity is how many of a certain organism an ecosystem can hold, limiting factors are things that can limit a population's growth. So for example say there's a forest and it has a low amount of food for deer. Food availability would be a limiting factor and it effects how many deer the forest can support.
The carrying capacity of an ecosystem is its maximum sustainable population size. When this limit is exceeded, resource competition can result in population decrease.
The carrying capacity of an ecosystem is the maximum number of individuals of a particular species that the environment can support indefinitely, given the available resources like food, water, and space. When the population exceeds the carrying capacity, resources become scarce leading to competition.
As a result, some individuals may fail to survive or reproduce, thus causing the population to decrease in size.
For example, consider a herd of deer in a forest. If food and water supply becomes limited due to their growing numbers and overconsumption, some deer might not get enough food and may consequently die of starvation, thus reducing the population number.
This phenomenon embodies the concept of population dynamics, a key aspect in studying ecosystems and biodiversity.

Great question!
The dry season of Indonesia is an annual period of little or no rainfall, and this is one of many reasons why Indonesia is so hot in the dry season.
° I can't say all the reasons, but I'll tell you a few more.
The tropics of Indonesia is dominated by the tropical rain belt, which moves from the northern to the southern tropics and back each year.
The tropical rain belt lies in the southern hemisphere very roughly from October to March - That's a whole half-year! 6 months!
