B. a crow eats blackberries from a bush
C. a gardener cuts tulips for a bouquet
D. a wave carries a coconut out to sea
Answers
the burrs will fall off of the fur and grown in a new place which is dispersal
The following are examples of seed dispersal: A crow eats blackberries from a bush, a wave carries a coconut out to sea, and a wolf picks up burrs on its fur that are preset in options A, B, and D.
What is seed dispersal?Seed dispersal is the movement of seeds from the parent plant to a new location, and this can be done by many, such as when a crow eats blackberries from a bush; that is an example of endo zoochory, where animals consume the fruits or berries of a plant and the seeds pass through their digestive system. A wave that carries a coconut out to sea is an example of hydrochory, where seeds or fruits are dispersed by water, and a wolf that picks up burrs on its fur is an example of epizoochory and in these ways seed dispersal occurs.
Hence, examples are A crow eats blackberries from a bush, a wave carries a coconut out to sea, and a wolf picks up burrs on its fur that are preset in options A, B, and D.

You are studying transplant rejection in a wild and genetically diverse population of mice. You have captured some of the mice for laboratory studies. You have four mice from a family. Mouse 1, mouse 2, and mouse 3 are littermates, thus they all share the same mother and father. Mouse 4 is the father of the other three mice. You transplant a small patch of skin from mouse 2 (the donor) onto mouse 1 (the recipient). There is a delayed inflammatory response and two weeks later the skin is necrotic due to transplant rejection. You decide to attempt another transplant. Which follow-up transplant is LEAST likely to be rejected?
a. skin from mouse 1
b. skin from mouse 2
c. skin from mouse 3
d. skin from mouse 4-incorrect
Answers
Answer:
b. skin from mouse 2
Explanation:
According to this question, a mice skin transplant is being conducted. Four mice labelled Mouse 1, Mouse 2, Mouse 3 and Mouse 4 are used for this experiment. A small patch of skin from mouse 2 (the donor) was transplanted onto mouse 1 (the recipient), however, it was eventually rejected by the recipient (mouse 1).
This transplant rejection is due to the fact that the recipient's immune system identifies the tansplanted skin as foreign, hence, begins to attack it, leading to the skin's necrosis or death. Based on this, the same transplant rejection will occur if skin patches from mouse 3 and 4 are used.
However, the immune system of mouse 1, which is the recipient, will identify skin patches from MOUSE 2 as less foreign than any other skin from other mice. This is because skin from that mouse has been used before, hence, the recipient's immune recognizes it when a follow-up transplant is conducted. This makes a follow-up transplant from MOUSE 2 be the least likely to be rejected.

How soon did the experimental group experience an improvement in lung function as measured by predicted FEV?
time taken to experience improvement:
How long was the improvement sustained?
duration of improvement:
By the end of the study, what was the absolute improvement of the experimental group relative to baseline?
Answers
Based on lung function tests, high FEV1 values indicates good lung function whereas low FEV1 values indicates impaired lung function.
What is lung function test?Lung function tests or pulmonary function tests are noninvasive tests performed to test how well the lungs are functioning.
The lung's primary function in gaseous exchange.
Thus, lung function tests determine how well the lungs perform gaseous exchange.
One parameter of lung function is Forced expiratory volume, FEV1.
Forced expiratory volume calculates the amount of air that a person can force out of their lungs in 1 second.
High FEV1 values indicates good lung function whereas low FEV1 values indicates impaired lung function.

litters with multiple offspring. However, an ecologist noted that the population size
of mice in a California grassland remains stable from year to year. The factors that
keep natural populations from increasing are collectively called
A. X-factor.
O B. limiting factors.
O C. carrying capacity.
O D. birth, death, immigration, and emigration.
Answers
Answer:
Limiting Factors
Explanation:
limiting factors determine a habitat's carrying capacity. hence the factor that keep natural population from increasing are collectively called limiting factors. Thus option B is correct.
What do you mean by carrying capacity of a species ?In an ecosystem the number of organism can survive successfully under certain resources referred as carrying capacity.
If a species population exceeds the environment's carrying capacity, the population depletes due to less availability of resources.
Several factors influence an environment include availability of food which is paramount for the survival of a species.
Water is the another essential factor which help animal in food digestion, regulate body temperature and elimination of waste products.
Ecological Conditions of an environment have an effect on carrying capacity of environment.
Space is another factor that provide a shelter to animals for survival and reproduction.
Thus option B is correct.

The aperture diameter (distance from side to side) of the opening of the telescope in millimeters. This is the area that lets light in. This telescope has a 18 mm aperture. Telescopes have a limit to how much useful magnification you can get, and this depends on the size of the aperture. Past that limit, and the image begins to break down, so it is not recommended to magnify higher than this amount. In general, the maximum useful magnification is 1.97x for every millimeter of aperture. Based on the size of the telescope’s aperture, what is the maximum useful magnification for this telescope?
Answers
Answer:
D. 35x
Explanation:
Given: For every millimeter of aperture, the maximum useful magnification = 1.97x
Aperture = 18 mm
Thus, the maximum useful magnification = 1.97 × 18 = 35.46
= 35x
