why do lichens and mosses get mostly replaced by larger plant species during succession
Answer:
Lichens that colonize bare rock secrete acids that break down the rock and start the soil-production process. Also, as lichens die, they provide some organic matter that also contributes to soil. Mosses can then colonize the thin soil; as mosses die, the soil thickens more allowing other hardy species to colonize

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.
The three conditions that encourage the presence of marine life in the ocean are proximity to land, water depth and.
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.

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.

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.

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.
