What is the function of each lymph organ?
Explanation:
The main role of the lymphatic system is the transport of cells of the immune system during the activation of immunity, lipids in the form of lipoproteins, as well as the introduction into the systemic circulation of various objects (small and large molecules, liquids, infectious agents, etc.), packed in delivery vehicles - exosomes and vesicles
The main role of the lymphatic system is the transport of cells of the immune system during the activation of immunity, lipids in the form of lipoproteins.
What is lipoprotein?Particles called lipoproteins are comprised of protein and fat (lipids). They deliver cholesterol to your cells through your bloodstream.
High-density lipoprotein, or "good" cholesterol, and low-density lipoprotein, or "bad" cholesterol, are the two main categories of lipoproteins.
LDL comes in the form of lipoprotein. These lipoproteins transport cholesterol to the artery cells. High levels of LDL particles can cause cholesterol to accumulate in your arteries and create blockages known as plaques. The term "hardening of the arteries" or atherosclerosis refers to this condition.
Therefore, The main role of the lymphatic system is the transport of cells of the immune system during the activation of immunity, lipids in the form of lipoproteins.

What do you think is the more ethical and feasible approach to wildlife preservation: change human behavior to limit human impact, or create sanctuaries to preserve some of the threatened animals’ population? Why?
Answer:
I think we need to do both, but I'll let you decide which you think sounds better for you personally (personally I think sanctuaries are often more effective).
Explanation:
Behavior changes It is not really ethical to continue to have a negative impact when changing our behavior can help, however, this may not be ideal as explained below
Sanctuaries It is often more feasible to create preservation sanctuaries because 1) it is hard to get everyone to change enough habits in order to create large-scale change and 2) some species require more immediate action to save, whereas changing human behavior may not be enough and/or at the right pace to preserve and expand the populations of endangered populations
Depending on the main threat to a specific population, the approach will obviously be different.
If a cell crossed over one time during Prophase I of Meiosis, how
many genetically distinct gametes would be produced?
Answer:
If crossing over doesn’t occur, then 2 out of the 4 daughter cells would be identical.
We have 46 chromosomes and are diploid meaning we got 1 set (23 chromosomes) from our mom and 1 set (23 chromosomes) from our dad.
In prophase 1, homologous chromosomes associate (chromosome #1 from dad and chromosome #1 from mom. They both code for the same things, but they are NOT identical)
Let’s compare mitosis to meiosis
On the left, see how in mitosis all chromosomes (even homologous) line up in single file (imagine all 46 lining up individually). When anaphase splits the sister chromatids (which are identical) in mitosis, each daughter cell gets the exact same genetic info.
(they get both homologous chromosomes: 1 from dad (yellow)and 1 from mom (purple) resulting in a full diploid set)
On the right in meiosis, see how the homologous chromosomes associate and will split? Chromosome #1 from mom (purple) is going to the left daughter cell while chromosome #1 from dad (yellow) is going to the right daughter cell. This means the two daughter cells will only have 1 set for chromosome #1 (either moms or dads but NOT both) and become haploid (1 set of 23 chromosomes)
Again in mitosis, all 46 lined up individually, but in meiosis the 23 from mom and 23 from dad first associate and each orient to decide which daughter cell gets the dads chromosome or the moms chromosome. They assort independently meaning just because dads chromosome #1 went to the left DOESN’T mean that dads chromosome #2 or #3 will go to the left. This gives a unique pattern of 23 chromosomes for the 2 daughter cells of meiosis 1 (a various mixture of moms and dads, but it is possible to result in a daughter cell with just moms and just dads set, though this would be a very small probability like 1 in 2^23 )
So each daughter cell of meiosis 1 is a haploid set (only 1 set instead of 2) and the opposite of the other (since 1 has fathers while the other has mothers for the same chromosome)
Meiosis 2 is just like mitosis. Here the sister chromatids separate producing 2 identical daughter cells
(identical if crossing over doesn’t occur. Crossing over only occurs on adjacent homologous chromatids)
If crossing over doesn’t occur then both sister chromatids are identical so that 2 out of 4 daughter cells will be exactly identical haploid sets. The other 2 are identical to each other as well.
Explanation:
Answer:
please give me brainlist and follow
Explanation:
Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.

Explanation:
Grouper or a type of fish that often wait until they are around 20 years old to reproduce based on this group or could be considered
The type of fish or Grouper which reproduce when they are around 20 years old is called monandric protogynous hermaphrodites.
The Groupers is a type of fish that is characterized by a large mouth and stout body.
They belong to the subfamily of Epinephelinae.
These groupers are known as monandric protogynous hermaphrodites because they mature to become only females which changes their sexes after sexual maturity.
This change in sex of the fish depends on internal or external triggers.
These reproductive changes usually occurs around 20 years of age in a groupers.
Therefore, the type of fish or Grouper which reproduce when they are around 20 years old is called monandric protogynous hermaphrodites.

a.
The populations of the other three species would also increase.
b.
The populations of the other three species would decrease.
c.
The grass population would decrease. The snake population and hawk population would increase.
d.
The grass population and hawk population would decrease. The snake population would increase.
Please select the best answer from the choices provided
A
B
C
D
Answer:
she is wrong , its c
Explanation:
The grass population would decrease. The snake population and hawk population would increase.
The correct answer is option C. . If you were to suddenly double the population of rabbits, the grass population would decrease due to overgrazing by the increased rabbit population.
What will happen in result to it ?As a result, the snake population and hawk population would increase due to the increased availability of prey. This is known as a trophic cascade, where changes in one trophic level affect the populations of other trophic levels in the food chain.
Option A and B are unlikely as doubling the population of rabbits would not necessarily cause the populations of the other three species to increase or decrease in a straightforward manner.
Option D is incorrect as there is no direct relationship between the rabbit population and the hawk population in this food chain.
