Answer: By looking at all the age population pyramids, this would be my best guess. Every territory is different with various populations, however, to the best of my knowledge, it would be the expansive pyramid.
Explanation: Expansive population pyramids are used to describe populations that are young and growing. They are often characterized by their typical ‘pyramid’ shape, which has a broad base and narrow top. Expansive population pyramids show a larger percentage of the population in the younger age cohorts, usually with each age cohort smaller in size than the one below it. These types of populations are typically representative of developing nations, whose populations often have high fertility rates and lower than average life expectancies.

The woolly mammoth was a relative of elephants that lived in the far north. There is much debate in the scientific community about what caused the extinction of mammoths. Climate models show that changing weather patterns stressed mammoth populations. Hunting by humans may have also reduced populations. The youngest mammoth remains on a continent are 10,000 years old.
Why did natural selection not cause mammoths to evolve new adaptations in response to environmental changes instead of becoming extinct?
A. There were too many offspring in the population.
B. There were too many different traits in the population.
C. There was not enough competition in the population.
D. There was not enough variation in the population.

Kyree is heterozygous. |f(W) ) is for waves, and ) if for no wave (w) r no waves What is Kyree's genotype & phenotype?
Answer:
Kyree b will have waves with a gwnotyoe; We
Explanation:
This question involves a single gene coding the possession or not of waves in humans. Allele W is for possession of waves while allele w is for no waves.
Heterozygous means contains two different alleles of the same gene. In this case, an heterozygous individual will possess allele W and w together i.e. Ww. Since the allele W is dominant over allele w i.e. can mask Its phenotypic expression, an heterozygous offspring (Ww) will phenotypically possess waves.

Consider the food web seen here. One member, the northern spotted owl, lives in cavities of trees in old-growth forests. Old
growth forests contain trees that are more than 200 years old and have not been cut, pruned, or managed. Imagine that these
forests have been heavily logged, Predict the outcome on this food web if the habitat of the owl is removed.
A)
The food web will collapse without this top-level consumer present.
B)
The niche filled by the owl will be filled by other predators like the hawk
and fox
The niche filled by the owl will be empty. The other animals within the
food web will grow unchecked.
D
Without the owl present, the empty niche will result in an overpopulation
of hawks. Eventually the lower-level consumers will disappear

Answer:
Exposure to sunlight.
Explanation:
Sunlight is important condition necessary for the presence of Marine life in ocean. This is because sunlight provide energy for ocean current and wind waves. When this energy is converted to heat, it a layer of warm water which is present at the ocean surface which support most Marine life. Sunlight produce light energy which is needed for Marine life like algae to photosynthesized in addition with carbondioxide and water in order to to produce necessary for survival for most Marine life.

What type of growth is characterized by a consistent increase in growth rate?
A) Exponential growth B) Carrying capacity growth
C) Logistic growth D) Stable growth
Answer:
It is Exponential growth.
Explanation:
Carrying capacity is the most amount of each population that a ecosystem can hold.
Logistic growth is not consistent.
The type of growth that is significantly characterized by a consistent increase in growth rate is known as Exponential growth. Thus, the correct option for this question is A.
What is Exponential growth?Exponential growth may be characterized as a type of growth that is followed by continuous breeders. The population of continuous breeders contains more individuals than a similar population breeding annually.
Some examples of this growth pattern include insects, humans, bacteria, internal parasites, larger plants, and animals. In this type of growth pattern, the value of carrying capacity must be reached fat as compared to other growth patterns like logistic growth.
Therefore, exponential growth is a type of growth that is significantly characterized by a consistent increase in growth rate. Thus, the correct option for this question is A.

How/why is ecosystem diversity important?
Answer:
Ecosystem diversity is a type of biodiversity. It is the variation in the ecosystems found in a region or the variation in ecosystems over the whole planet. Biodiversity is important because it clears out our water, changes out climate, and provides us with food.
Explanation:
It clears out water , makes safe climate change and provides everyone with a meal
Which molecules are easily diffuse across the plasma membrane
Answer:
Water diffusion is called osmosis. Oxygen is a small molecule and it's nonpolar, so it easily passes through a cell membrane. Carbon dioxide, the byproduct of cell respiration, is small enough to readily diffuse out of a cell. Small uncharged lipid molecules can pass through the lipid innards of the membrane.

A base pair (bp) is the pairing of two nucleobases located on two complementary strands of DNA or RNA. This pairing is carried out by hydrogen bridges. There are four types of nucleic bases: A-T-C-G, these letters Adenine, Thymine, Cytosine, and Guanine. A with T and C with G.
It is also necessary to take into account the antiparallel character of the DNA strands. If a strand is in the 5 '3' direction, its complete strand is in the 3 '5' direction.

Why is water so effective at hydrogen bonding?
Choose 1 answer:
(Choice A)
The hydrogens in water are ionically bonded to the oxygen.
(Choice B)
Hydrogen is more electronegative than oxygen, so it is more likely to donate its electrons to oxygen.
(Choice C)
Oxygen is very electronegative and strongly attracts hydrogen's electron.
(Choice D)
There are two hydrogens, doubling the positive charge on the water molecule.
Answer:
Choice A
Explanation:
Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.
