Scientists have studied the return of plant life on Mount St. Helens ever since the volcano erupted in
1980. Wildflowers began colonizing the area, followed by shrubs and small trees. Scientists predict
that it will likely take hundreds of years before the area returns to a forest dominated by fir and
hemlock trees. These changes are an example of:
a. humans degrading an ecosystem by removing wildflowers
b. the loss of genetic variation in a plant species
C. the growth of a forest through ecological succession
d. the biological evolution of wildflowers, shrubs, and trees

Answers

Answer 1

Answer:

C.

The ecosystem there will definitely go through ecological succession by which the structure of the flora there will evolve over time into forests.

If the following events are arranged in the order in which they occur for an animal hiding and holding still in response to seeing a predator, which is the fourth event in the series?.

Answers

Animal hiding-holding still response follows the reflex arc sequence. The fourth event in the series is option B) signaling by efferent PNS neurons.

When the animal receives the stimuli, it responds to them. In the case of hiding-holding still response, the animal might freeze due to motor inhibition that reduces excitatory signals.

The reception and reaction to stimuli follows the reflex arc sequence.

What is reflex arc?

The reflex arc refers to the sequence of events since the body receives an external stimulus until it reacts.

The correct answer is B) signaling by an efferent PNS neurons.

Question: As a result (because) of diffusion, the concentration of many types of substances:
A: always remains greater inside a membrane.

B: eventually becomes balanced/equilibrium on both sides of a membrane.

C: always remains greater on the outside of a membrane.

Answers

|| ▼ Answer ▼ ||

B: eventually becomes balanced/equilibrium on both sides of a membrane.

|| ✪ Explanation ✪ ||

Diffusion is the movement of molecules from a high to a low concentration. The effect of diffusion on different substances' concentrations is balance/ equilibrium on both sides of a membrane. In the process of the movement of molecules, the concentration becomes balanced. A typical example of diffusion is a perfume sprayed inside a room. The smell of the perfume will eventually be balanced in the entire room.

what is vegatative propogation?​

Answers

Answer:  Vegetative propagation is an a s exual method of plant reproduction that occurs in its leaves, roots and stem.

Answer:

VEGETATIVE PROPAGATION

regeneration of new plant from the vegetative part or organ of the parent plant is called vegetative propagation vegetative propagation is used full to separate the plant in wider region mother plant get favourable condition if then colonized to the reason by vegetative propagation the offspring adapted

1 NATURAL VEGETATIVE PROPAGATION-

BY ROOT -

the interact root of several Woody plants such as guava sisoo grow just below the soil produce advantages but should just below the soil produce but should develop from this bird which give rise to new plant

BY STEM -

stamp is the source of natural vegetative reproduction in several plants modification or found in stem to perform vegetative propagation

a Runners- the weak stem of creep forward on the soil that downwardly from node axillary bud are present in the axils of scale leaves node

b s ucker - rise time in similar to runner but it is underground its main stem grow upward and develop advantages root from underground

c offset- the thick and fleshy runner of hydrophytes plant is called offset

BY LEAVES

Titan plant develop adventirious bud on their leaves this word after separating from Mother plant give rise to new plant

BY BULBILS

they are fleshy but which are produced in the axils of leaves in the auxiliary Bud

ARTIFICIAL VEGETATIVE PROPAGATION-

GRAFTING

it is the most common method of vegetative reproduction in this method variety of shame spices can be converted into plant of better variety in the technique of trade off to plant are joined in such portion of one part called stock is joint with another plant is called scion

BUDDING-

it is the superior and modern method of plant propagation in this method but of plant are superior varieties grafted in the stem of plant in variety after making oblique you cut up to the bark of stem after fue with this but join with plant as result formed on the new plant

LAYERING-

the method of inductor root formation the branches while they are still attached to a mother plant is called layering

CUTTING -

any part of plant root stem or leaf which has the power to develop itself into a new plant after separating from the mother plant is called cutting

IMPORTANCE OF PROPAGATION

the plant which have lost their power to produce seeds like Banana grapes Rose in it can be propagated by vegetative means only the plant which produce seed in less number are usually propagated vegetative leaf the change of some chemical x-ray and environmental variation as temperature can be studied easily in plant which vegetative propagation the tissue culture technique of vegetative propagation is used to raise disease free plant

Frontal Inversions are the inversions that is caused by a shallow "cold air" blowing in under warmer air. An inversion traps air pollutants, such as smog, close to the ground.

how are utah and mexican praire dogs genes alike

Answers

Answer:

In terms of genetic variation, allelic richness (A) estimated through rarefaction resulted in 1.6–3.0 mean alleles per colony, and no private alleles were found. Mean genetic diversity (HE) was 0.525 (SD = 0.11), with values ranging from 0.276 (SD = 0.25) to 0.618 (SD = 0.09).

Explanation:

Utah prairie dog (Cynomys parvidens), and Mexican prairie dog (Cynomys mexicanus)—all of which may be considered rare (Hoogland 2006a). After 200 years of shootings, poisonings, conversion of habitat, and more recently plague, prairie dog numbers are a fraction of what they once were. Two of the species (Utah and Mexican) are listed as threatened or endangered under the Endangered Species Act (ESA).
