Answer:
Reproduction in prokaryotes is asexual and usually takes place by binary fission. Recall that the DNA of a prokaryote exists as a single, circular chromosome. Prokaryotes do not undergo mitosis. Rather the chromosome is replicated and the two resulting copies separate from one another due to the growth of the cell.

In an experiment investigating the mechanism of protein secretion, researchers
tracked the movement of radioactively labeled polypeptides in pancreatic cells. At
various times after the labeling, samples of the cells were observed using an electron
microscope to determine the location of the radioactively labeled polypeptides.
Figure 1 summarizes the results at 5 minutes, 15 minutes, and 30 minutes. The dark
dots in the figure represent the radioactively labeled polypeptides.

Figure 1. Radioactively labeled polypeptides
Using the experimental results, describe the pathway that secretory proteins take
from their synthesis to their release from the cell. (3 Points)
Answer/Explanation:
First, the polypeptides are synthesised and folded in the endoplasmic reticulum, which is a series of folded membranes.
Then, the polypeptide is packaged into vesicles and moved into the Golgi apparatus, which are stacks of flattened sacs. At the Golgi apparatus, the polypeptide is modified, forming the final structure of the protein. The proteins are then packaged in to vesicles to be transported to their final destination outside of the cell.
The proteins are delivered outside the cell in vesicles via a process called exocytosis. The vesicles reach the membrane, fuse with the membrane, and are then delivered outside the cell.

give two advantages of a coelom
Answer:
The advantages of the coelom in animals include the fact that the coelom, a cavity filled with fluid around the organs, provides a hydrostatic skeleton to aid movement, and allows for more efficient circulation of nutrients and removal of wastes.

What term includes all the biotic and abiotic factors in an area?
ecosystem
population

Answer:
The answer is ecosystem
HOPE THIS HELPS! :)
Ecosystem includes all the biotic and abiotic factors in an area.
What is ecosytem?An ecosystem is a geographical region in which plants, animals, and other species, as well as weather and landscapes, collaborate to build a living bubble.
What are the biotic and abiotic components of ecosystem?Living creatures that have a direct or indirect impact on other species in an ecosystem are referred to as biotic components. Plants, animals, and microbes, as well as their waste products, are examples.All chemical and physical elements, or non-living components, make up the abiotic components of an ecosystem. Abiotic components can differ from one ecosystem to the next and from one place to the next. They mostly serve as life supporters. They control and limit the amount, variety, and development of biotic components in an ecosystem. As a result, they are referred to as limiting factors.Hence the correct option is A i.e. Ecosystem.

9. Knowing what you know about how a substance travels in
diffusion, in order for oxygen to leave the alveoli and enter the
blood, there would be a [ HIGHER or LOWER] concentration of
oxygen in the alveoli compared to the blood.
Answer:
Higher
Explanation:
Molecules such as oxygen move from a higher concentration to a lower concentration across a semi-permeable membrane. This process is called simple diffusion.
Therefore, for oxygen to leave the alveoli and enter the blood, there would need to be a higher concentration of oxygen inside the alveoli and a lower concentration of oxygen in the blood.
In order for oxygen to leave the alveoli and enter the blood, there would be a higher concentration of oxygen in the alveoli compared to the blood.
Diffusion is the process by which compounds or substances move from a
region of higher concentration to that of a lower concentration. This helps to create an equilibrium in the concentration of the substance to prevent cell death due to shrinking etc,
The alveoli is found in the lungs which is the organ of respiration and the
oxygen present is usually in higher concentration and moves to regions of
low concentration in the blood.

What is the relationship between chromosome numbers in body cells and sex cells?
Answer:
In sexually reproducing organisms, the number of chromosomes in the body (somatic) cells typically is diploid (2n; a pair of each chromosome), twice the haploid (1n) number found in the sex cells, or gametes. The haploid number is produced during meiosis.
The number of chromosomes in somatic (body) cells of sexually reproducing animals is normally diploid (2n; a pair of each chromosome), which is twice as many as the haploid (1n) amount found in the sex cells, or gametes. Meiosis is when the haploid number is formed.
What chromosome numbers in body cells and sex cells?The average human cell contains 23 pairs of chromosomes (46 total chromosomes). Half was provided by the mother, and the other half by the father. When you are born, two chromosomes—the X and the Y chromosome—determine whether you are a boy or a girl.
Gametes, which include sperm and eggs, are reproductive cells. The number of chromosomes must be cut in half as gametes are created.
Therefore, The gametes must include half of the chromosomes found in healthy body cells because the zygote must contain genetic material from both the mother and the father.

Which of the following distinguishes why "biosolid" is another name for fertilizers made from sewage sludge?
Answer:
Sewage sludge is a biodegradable way of recycling human waste
Explanation:
What distinguishes "biosolid" in its use as fertilizer made from sewage sludge is because sewage sludge is a biodegradable way of recycling human waste. Sewage sludge is known to be a semi-solid material that is produced during sewage treatment. Biosolids are actually used as fertilizers due to the treatment the sewage sludge has undergone in order to make it fit for land use. In the process of manufacturing biosolids, certain processes are carried out in order to make it meet pathogen requirements for land application and surface disposal. These biosolid are biodegradable and that's one of the reasons why they are suitable as fertilizers.
