Which statement below best describes the purpose of meiosis in creating gametes?
The purpose of meiosis is to produce gametes, or sex cells. During meiosis, four daughter cells are produced, each of which are haploid (containing half as many chromosomes as the parent cell).
The purpose of meiosis is to create gametes. Thus, it reduces the number of chromosomes to half.
What is meiosis?In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm). Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent).
The egg and sperm that combine during fertilization must be haploid or have only one pair of chromosomes, in order to sustain this state. Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are gametes.
In humans, autosome cells contain 46 chromosomes, while gametes contain 23 chromosomes. Hence, the main purpose of meiosis is to divide the genetic material in half.

I heard that Bloodtype O is strong to the malaria virus. Can someone tell me why is that? I need direct sources for the information. Thank you.
Answer:
With neither A or B antigens, this blood group has different receptors on its red blood cells, and these are not as easily taken over by malaria. "Hence, rosettes formed in blood group O [red blood cells] tend to be smaller, weaker and more unstable," the authors write in the new review

Which one of the following components is responsible for the clotting of blood? Select one: O a plasma O b. leukocytes O c. hemoglobin O d. thrombocytes
Answer:
D. thrombocytes
Explanation:
The main function of thrombocytes is to stop the bleeding of injured blood vessels. In mammals, thrombocytes are anucleated cell fragments called platelets.
Thrombocytes is responsible for the clotting of blood.
What are thrombocytes?
The microscopic blood cells known as platelets, or thrombocytes, aid in blood coagulation. Your body naturally stops bleeding with platelets.
Plasma, red, white, and platelet-containing blood cells make up whole blood. Platelets, the lightest component of whole blood, are pushed to the walls of your blood vessels because they are the heaviest part of the blood.
This allows plasma and blood cells to flow through the center, allowing platelets to reach injury rapidly to stop bleeding.
Therefore, Thrombocytes is responsible for the clotting of blood.

Classify each type of cell transport.
Answer:
Diffusion is a passive process of transport.
Endocytosis is a type of active transport
exocytosis are active transport processes.
osmosis a form or passive transport
Facilitated diffusion is a type of passive transport
Hope this helps!!!!
Classifying each type of cell transport :
Diffusion : Passive transport Endocytosis : Active transportExocytosis : Active transportFacilitated diffusion : Passive transport Osmosis : Passive transportA passive transport system is the movement of solute in solution across regions of different electrochemical potentials on either side of a cell membrane ( i.e. from higher concentration to lower concentration) examples include : diffusion, osmosis and facilitated diffusion. while
Active transport system is the movement of molecules across a cell membrane by the application of cellular energy and not the difference in electrochemical potential. examples include Endocytosis and exocytosis
Hence we can conclude that Classifying each type of cell transport :Diffusion ; Passive transport. Endocytosis : Active transport. Exocytosis : Active transport. Facilitated diffusion : Passive transport. Osmosis : Passive transport .

Explanation:
A toy car accelerates 1.25 m/s2 when a child pushes it with a force of 0.1 newtons. What is the mass of
the car?
Answer:
0.089
Explanation:
The formula to solve for mass is:
m=F/a
So, The force is 0.1, and the acceleration is 1.25^2.
First you must square 1.25, which will give you 1.12 ( I rounded).
Now, we have 0.1/1.12, which equals 0.089, or 0.09.

The movement of individuals into an area is called
A. Demography
B. Carrying capacity
C. Immigration
D. Emigration
Answer:
D. Emigration
Explanation:
The answer is D. because the actual definition for emigration is: "The act of leaving one's own country to settle permanently in another; moving abroad." The definitions between immigration and emigration are very similar but the actual definition for immigration is: "The action of coming to live permanently in a foreign country." so I would stick with D.

Answer:
5. c. active transport of molecules across a membrane
6. b. osmosis
7. d. water entered the cells of the lettuce by osmosis
Explanation:
5. The diffusion of water does not involve the budding of the cell membrane. The production of proteins amino acids and asexual reproduction are unrelated to the movement of molecules across the cell membrane. Therefore, this is active transport of molecules across a membrane.
6. The diffusion of water from a high concentration to a low concentration of water across a selectively permeable membrane is called osmosis. Transpiration is the process by which water leaves plant cells. Active transport requires energy. Capillary action is when water moves as a result of adhesion/cohesion.
7. When water enters the cells by osmosis, the cells become more turgid, making the lettuce crisp.
