Answer:
B. ERExplanation:
is just my opinionbut hope it helps youAnswer:
[A] Cell Wall
[B] ER
[D] Chloroplast
Explanation:
The cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the plant cell.
The ER is the production, processing, and transport of proteins and lipids.
Chloroplasts enable the conversion of light energy into the chemical form without which the plants would be unable to perform photosynthesis.

Dogs do not get measles because their cells lack the correct receptor sites for that virus. True False
Answer:
True
Explanation:
A viroid is a completely developed infectious agent composed of nucleic acid and surrounded by a capsid. Glycoprotein spikes are found on the capsids of all viruses.
The answer is TRUE.
Dogs do not get measles because their cells lack the correct receptor sites for that virus. A viroid is a completely developed infectious agent composed of nucleic acid and surrounded by a capsid. Glycoprotein spikes are found on the capsids of all viruses.
What happens if you get measles?Measles can lead to serious problems if it spreads to other parts of the body, such as the lungs or brain. Problems that can be caused by measles include pneumonia. meningitis.
What is the main cause of measles?Measles is caused by a virus found in the nose and throat of an infected child or adult. When someone with measles coughs, sneezes or talks, infectious droplets spray into the air, where other people can breathe them in. The infectious droplets can hang in the air for about an hour.

In eastern gray squirrels, Sciurus carolinensis, the allele for black fur (B) is dominant to the allele for gray fur (b). In a particular population of gray squirrels, 64% have black fur and 36% have gray fur. A researcher calculated the allelic frequencies to be B = 0.4 and b =0.6. Five years later, the researcher returned to the location and determined the allelic frequencies within the squirrel population to be B = 0.6 and b = 0.4. Which of the following could best explain the increase in the frequency of the Ballele in the population after five years?
(A) The frequency of the B allele increased because it is the dominant allele.
(B) The frequency of the Ballele increased because squirrels with gray fur exhibited greater fitness.
(C) The frequency of the B allele increased due to the selective pressures of the environment.
(D) The frequency of the Ballele increased because black squirrels randomly mate with other eastern gray squirrels.
The frequency of the B allele increased due to the selective pressures of the environment (Option C). It is fundamental in evolution.
What is evolution?Evolution can be defined as descendence with modification, which mainly happens due to natural selection.
Natural selection refers to the differential survival and reproduction of the fittest organisms in a population.
Selective environmental pressures affect reproduction/survival and favor the most adapted organisms.

Given what we know, we can confirm that the zone in which this process is taking place is known as the zone of cell proliferation.
What is the zone of cell proliferation?This is an area of the bone that is widely studied in histology. It is important for the formation of bones and additional bone cells. This area can be identified and studied due to the basophilic nature of the cells that occupy it.

Why are rising carbon dioxide levels in the atmosphere harmful?
Carbon dioxide blocks the sun’s rays from reaching earth’s surface.
Carbon dioxide harms plant life.
Carbon dioxide traps heat in earth’s atmosphere.
Carbon dioxide increases peoples risk of asthma.
Answer:
C.) Carbon dioxide traps heat in earth's atmosphere
Explanation:
A.) is incorrect because it does not block the rays. Rather, it keeps the heat from the rays from escaping the atmosphere.
B.) is incorrect because carbon dioxide is actually necessary for plant life.
C.) is correct because carbon dioxide absorbs the heat that should be escaping the atmosphere. As a result, the heat stays within the atmosphere and increases Earth's temperature. This can lead to rising sea levels, loss of animal habitats, species extinction, etc.
D.) is incorrect because while increased carbon dioxide levels have been linked to worsening asthma, this connection is not direct and does not affect all age levels. This answer may be true, but there is a better, more obvious choice.
Rising carbon dioxide levels in the atmosphere harmful because carbon dioxide traps heat in earth’s atmosphere.
What do you mean by rising carbon dioxide levels?"Most of the energy comes from burning fossil fuels, like coal and oil. This releases carbon dioxide into the atmosphere. As carbon dioxides levels rise, earth's temperatures rise too."
What is rising the carbon dioxide levels?"Human activities have increased the concentration of carbon dioxide in the atmosphere, amplifying earth's natural greenhouse effect."
What is an atmosphere?"An atmosphere is the layers of gases surrounding a planet or other celestial body."
What are the different layers of atmosphere?The different layers of the atmosphere from lowest to highest are:
troposphere,stratosphere,mesosphere,thermosphere,exosphere.What would happen if carbon dioxide is increased in the atmosphere?"The increased percentage of carbon-dioxide will cause the greenhouse effect, i.e. it will not allow the hot rays of the sun to escape from the atmosphere after reflection once they enter the earth's atmosphere, thereby increasing the temperature of the earth."

Why is it ecologically relevant for plants to have their seeds dispersed.

Dispersal of seeds is very important for the survival of plant species. If plants grow too closely together, they have to compete for light, water and nutrients from the soil. Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources

How does the domain Eukarya differ from the other two domains?.
The domain Eukarya differs from the other two domains.
Eukarya vary from the Archea and Bacteria in that their cells are eukaryotic, which means they include a membrane-enclosed nucleus and different membrane-enclosed organelles. Archea and Bacteria have prokaryotic cells, which means their cells do now no longer include a membrane-enclosed nucleus or different membrane-enclosed organelles. Presence of a double membrane nucleus.
What is the unique feature of eukarya?Unlike different organisms of different domains (that have their genetic cloth suspended withinside the cytoplasm), the DNA of eukaryotic organisms is saved withinside the nucleus.
