Answer:
Microvilli are typical of these cells. These projections increase the absorptive area on the cell surface.
Explanation:
Epithelial cell surfaces show different structure shapes that allow the cells to adapt to and accomplish their functions. Most of these structures are related to the absorption surface and the need to move substances.
The development of microvilli is very common in epithelial cells. These are folds or finger-like projections emerging from the apical surface of the cell. Their principal function is to absorb. The microvilli of the intestinal epithelium are very uniform in size and distribution.

a, selection
b. overproduction
C. competition
d, variation
e, speciation
The fact that the population of moths includes both brown and green moths is an example of variation.
What is Population?The population is the group of individuals belonging to the same species living in the same area at a particular time.
The population of moths consists of two types of genetic variations, which means there is an existence of two different alleles that are responsible for the expression of two different colours (brown, green) in the population of moths.
Therefore, the fact that the population of moths includes both brown and green moths is an example of variation.

Does the stratosphere have a high or low temperature also what is the temperature
Answer:
Explanation:
The stratosphere is the second-lowest layer of Earth’s atmosphere, starting at 10 kilometers above the surface. Unlike the troposphere, the temperature in the stratosphere increases with altitude. At the top, the temperature is around 32°F – almost 100 degrees higher than the bottom.

how much force would is required to stop a 1200kg car in 2 seconds if the car is traveling at 22 m/s
The force required to stop the car is 13200 N.
We have car of mass 1200kg.
We have to determine how much force is required to stop this car in 2 seconds.
What is Force ?
Force is defined as the product of mass and acceleration. Mathematically-
F = ma
According to the question -
Using first equation of motion -
v = u + at
0 = 22 + a x 2
-22 = 2a
a = -11 m/s².
The force required to stop the car = M x a = 1200 x |a| = 1200 x 11 =
13200 N
Hence, the force required to stop the car is 13200 N.

A cross between a white rooster and a black hen results in 100% blue offspring. When two of these
blue offspring are mated, the probable phenotypic ratio seen in their offspring would be
A) 1:1:2 B) 3:1 C) 1:2:1
D) 2:1:1
Answer:
c
Explanation:
they each contain a gene from their father, their mother, and themselves, since they are both blue there will be 2 blue genes, 1 black and 1 white
A cross between a white rooster and a black hen results in 100% blue offspring, so when two of these blue offspring are mated, the result is 1:2:1, which is option c, as 1 is white, 2 are blue, and 1 is black.
What is the significance of the genetic crossing?Due to incomplete dominance, genetic crossing occurs between two animals, such as one black hen and one white rooster, and the offspring are blue. When these two heterozygous blue birds cross, a total of four hens and roosters offspring are formed: 1 is black, 1 is white, and 2 are blue and this genetic crossing can also increase genetic diversity within a population due to meiosis.
Hence, a cross between a white rooster and a black hen results in 100% blue offspring, so when two of these blue offspring are mated, the result is 1:2:1, which is option c, as 1 is white, 2 are blue, and 1 is black.

Somatic cells refer to all the cells of the body except for the germ cells or as a whole-cell in the case of the unicellular organism.The somatic cells are obliged to build the whole body parts.Somatic cells divide only by the process of mitosis.The germ cells are the generative cells liable for reproducing the offspring.Germ cells generate cells like sperm in males and eggs in females.Germ cells are the unique cells that undergo both mitosis and meiosis to produce gametes.The germ cells produce haploid (N) cells.Therefore, the two somatic cells of an individual will be identical as they carry the same genetic information.

A. How do the oxygen (O2) and carbon dioxide (CO2) levels change over time?
Answer: How does CO2 level affect oxygen production? increasing CO2 production increases oxygen production. ... Greater flow of oxygen corresponds to a higher rate of photosynthesis.
Explanation:
Oxygen ( O₂ ) and carbon dioxide ( CO₂ ) levels change over time ;
Due to man-made and natural processes
Natural processes such as Photosynthesis and the storage of carbon in the biosphere and hydrosphere. cause a varying change in the levels of CO₂ present in the atmosphere because during photosynthesis CO₂ is used by green plants while the amount of stored carbon in the hydrosphere affects the level of available carbon in the atmosphere in general.
Man-made processes which includes the burning of fossil fuels and the release of CFC's into the atmosphere through gas flaring also the indiscriminate burning of bushes contribute immensely to the levels of carbon found in the atmosphere.
Hence we can conclude that Oxygen ( O₂ ) and carbon dioxide ( CO₂ ) levels change over time ; Due to man made and natural processes
