Answer:
The second cell would not be able to produce as much food because it could not capture sunlight.
Explanation:
The second cell would not be able to produce as much food because it could not capture sunlight. The number of chloroplasts in a cell can also affect its shape and size, as well as its ability to store water, but the primary function of chloroplasts is to produce food through photosynthesis.
What are chloroplasts?Chloroplasts are organelles found in plant cells and some algae that are responsible for photosynthesis, the process by which plants convert light energy into chemical energy in the form of glucose. They are typically oval-shaped and range in size from 5 to 10 microns in diameter.
The chloroplast is surrounded by two membranes, an outer membrane, and an inner membrane, with a space between them known as the intermembrane space. The inner membrane encloses a fluid-filled space called the stroma, which contains enzymes and other molecules needed for photosynthesis.

Which of the following have been changed or altered
due to climate change.
A. Droughts
B. Flooding
C. Melting of polar ice caps
D. All of the above
Answer:
D.
Explanation:
Droughts come from an intense increase in temperature. This causes water/moisture to evaporate from the ground. This is caused by greenhouse gas emissions which makes things a lot warmer. Thus, the temperature rises.
C and B are linked. The icecaps melt which cause the water levels to rise. When the icecaps melt, the water goes into the ocean and causes a rising in the sea level, thus meaning floods can happen.
Droughts, flooding and melting of polar ice caps have been altered or changed due to climate change.
What are the effects of climate change?A change, which comprises both global warming and its influence on the weather patterns of the Earth is known as a climate change. There have been many periods of climate change, however, the present changes are more brisk and are not because of any kind of natural events.
The change in climate is resulting in the melting of polar ice caps, which eventually results in the elevation of sea levels and the oceans are turning warmer than before. Climate change is resulting in more intense droughts and flooding. The continuous change in climate due to human activities are posing a threat to the species, places, and livelihoods.
Thus, the correct answer is option D, that is, all of the above.

C. Sympathetic allows the body to relax; parasympathetic helps the
body achieve tension.
D. Sympathetic prepares the body to react; parasympathetic helps the body gain and conserve energy.
Answer:
D. Sympathetic prepares the body to react; parasympathetic helps the body gain and conserve energy.
Explanation:
the sympathetic system is your fight or flight response
parasympathetic system is the rest and digest
The statement, that is, the sympathetic prepares the body to react, and parasympathetic helps the body to conserve and gain energy correctly describes the functions of parasympathetic and sympathetic nervous system.
What are the functions of parasympathetic and sympathetic nervous system?Both the parasympathetic and sympathetic nervous system are the components of the autonomic nervous system. The sympathetic nervous system is situated close to the lumbar and the thoracic regions in the spinal cord.
Its main role is to instigate the body's flight or fight response. It does this by monitoring the rate of respiration and the rate of the heart. Therefore, it prepares the body to react.
On the other hand, parasympathetic nervous system is situated in between the medulla and the spinal cord, and works to stimulate the body's digest and rest and breed and feed response. Therefore, it helps the body to conserve and gain energy.
Thus, the correct statement is option D.

Proteins synthesis is accomplished primarily by the interaction of which two cell structures?
A:vacuoles and mitochondria
B:ribosomes and vacuoles
C:nuclei and ribosomes
D:nuclei and mitochondria
Answer:
C
Explanation:
Protein synthesis occurs through a chain of processes.
1) transcription of DNA in nucleus to form a RNA strand
2) RNA then undergoes modifications to form a mRNA
3) mRNA then migrates out of nuclear pore and complexes with a small and large ribosomal subunit to form a translational complex
4) translation occurs at the ribosomes to form a polypeptide by joining correct amino acids together through the formation of peptide bonds
5) polypeptide gets modified chemically and folded physically to form a protein in rough endoplasmic recticulum and golgi body.
Protein synthesis is accomplished primarily by the interaction two cell structures namely; nuclei and ribosomes.
PROTEIN SYNTHESIS:
Protein synthesis is the series of process that involves how proteins are produced by genes. Protein synthesis takes place in two stages namely: transcription and translation.TRANSCRIPTION:
Genes are stored in the nucleus as DNA, hence, the process of synthesizing mRNA from DNA called transcription, takes place in the nucleus.TRANSLATION:
Translation is the process whereby mRNA is used to synthesize proteins in the ribosome. The mRNA, produced in the nucleus of a cell moves to the ribosome, which is the site of protein production. Therefore, protein synthesis is accomplished primarily by the interaction two cell structures namely; nuclei and ribosomes.Learn more at: https://brainly.com/question/241631?referrer=searchResults

Cell Division and the Cell Cycle, can anyone write me a essay that is three paragraphs long on that topic. I stink at it
answer:
The cell cycle is a cycle of stages that cells pass through to allow them to divide and produce new cells. It is sometimes referred to as the “cell division cycle” for that reason. ... The two main parts of the cell cycle are mitosis and interphase.
The cell cycle is the replication and reproduction of cells, whether in eukaryotes or prokaryotes. It is important to organisms in different ways, but overall it allows them to survive. For prokaryotes, the cell cycle, called Binary Fission, allows for them to live on by dividing into two new daughter cells.cell division takes place in the cell cycle.
Cell division is the process by which a parent cell divides into two or more daughter cells. Cell division usually occurs as part of a larger cell cycle. ... Prokaryotes (bacteria) undergo a vegetative cell division known as binary fission, where their genetic material is segregated equally into two daughter cells.
Purpose of Cell Division. Cell division is an essential process for organism creation, growth, and repair. There are two main types of cell division in humans. Cells can divide to make reproductive cells, sperm and eggs.
The cells in our body are highly intelligent. They know when to duplicate themselves and when to rest or stop dividing altogether. ... If the cell passes through each phase and makes it through each checkpoint, then the parent cell replicates and each of the new cells then enter into their first cell cycle.the cell cycle and cell division is very benificial and important for our body.

please please helppp meee A mammalogist is studying the behavior of the rain forest jaguar. She spots a jaguar
crouched on a tree branch in the understory, waiting to pounce on a rain forest herbivore
called a tapir. The hair of the jaguar is white with black spots. The jaguar has learned the
habits of this tapir, and he knows it uses this trail each evening. The cat is panting in the
steamy heat to stay cool, and its muscles tense as the tapir approaches. The jaguar pounces
and stabs its prey with long, sharp incisors. Although its meal is large, it will need to hunt
and eat again in a day or two to ward off its hunger.
Compose a four-to five-sentence paragraph that summarizes the general mammal
characteristics you can identify from the details of the story about the jaguar.
Answer:
The rainforest jaguar, exhibits a well-known mammal characteristic, as it waits for its opportunity to pounce on its prey. Mammals are known to be dominant in its environment, actively seeking its targets. Furthermore, the hairs on the jaguar would be an indicator of its status as a mammal. As mammals are known to have hair, and it is thus a mammal characteristic. They are known to be warm blooded, and one instance in the passage that hints at the jaguar's warm bloodedness would be when it pants in order to stay cool.
Note:
this is really vague lol, since I don't know your teacher's lesson plan, so I'm not sure what mammal characteristics are pointing towards (biological, or behavioral?) so note that this response might not be what your teacher is looking for.
