When comparing plant cells to animal cells, which organelle is only present in plant cells?(1 point)
mitochondrion
cell membrane
cytoplasm
cell wall
Answer:
- cell wall -
Explanation:
The answer is a cell wall because the cell wall in a plant acts as a 'skeletal system'.
So tell yourself does, an animal that already has a skeleton, need the cell wall?!
NO! It dan't! That's why animals don't have the cell walls and plants do.
!!! Hoped that helped !!!
When comparing plant cells to animal cells, cell wall is only present in plant cells. The correct option is D.
What is cell wall?A cell wall is a structural layer found just outside the cell membrane that surrounds some types of cells.
It can be tough, flexible, and rigid at times. It provides structural support and protection to the cell, as well as acting as a filtering mechanism.
The cell wall is made up of a network of cellulose microfibrils and cross-linking glycans embedded in a matrix of pectin polysaccharides that is highly cross-linked. Lignin can be found in secondary cell walls.
It provides a structural framework for plant growth and serves as the plant's first line of defense against pathogens.
The cell wall must also retain some flexibility so that it can be rapidly remodeled in response to developmental, biotic, or abiotic stimuli.
Thus, the correct option is D.

Can sunlight change the distribution of traits in a population?(1 point)
No, because the environment can only change behaviors.
Yes, because the environment is the only factor that can change traits.
Yes, because the environment can factor into the distribution of traits.
No, because the environment can only change traits in individual organisms.
A number of factors including environmental factors (for example sunlight) can also play a role in how the traits in a particular population is distributed.
Sunlight can change the distribution of traits in a population because the environment can factor into the distribution of traits.
The distribution of traits is changed when factors in the environment change/evolve and influence natural selection. These environmental factors including sunlight alter the selection of traits passed to generations and can have an effect on the distribution of the traits on Earth.Learn more about environmental factors: https://brainly.com/question/3638961
The sunlight can be a factor for the distribution of traits in a population. Option C is correct.
Natural selection:
It is phenomenon in the evolution in which a population of species in distributed in the habitat or evolve by the certain traits that fits in the nature.
For example-
A population of a species have two types of traits,
1. Individuals that can bear the intense light.
2. Individuals that can not bear the intense light, prefer low light.
After several generation the whole population will divide in the groups according to their ability to bear the intensity of light.
It can also result in the new species that only wake up at night to avoid the sun.
Therefore, the sunlight can be a factor for the distribution of traits in a population.

radar maps?
Answer:
A. These signals have been calibrated against actual visual and location readings for the amount of rain falling and cloud water content. ... Thus the computer generates a visual image according to the reflectivity of the amount of water in colors on a map.
B. Reflectivity of an object helps indicate the amount of water that a cloud may carry. The stronger the reflected signal from the radar signal sent out, the easier the meteorologist will be able to tell what to expect. ... This in turn is interpreted by the meteorologist from past experience as what to expect in the future.
