Answer:
Number of chromosomes
Explanation:
Meiosis is a specialized type of cell division in which the gametes are produced.
A diploid parent cell first replicates its DNA. Then, two rounds of cell division occurs to produce 4 haploid cells, each with half the amount of chromosomes. These gametes fuse during fertilization to restore the diploid state.
Therefore, meiosis changes the number of chromosomes.

2. Which blood type would you have if antibodies A and B were made during your first year of life?
Answer: the possible possibilities are 3 if u have an A and B type of antibodies.
Explanation:
it can be -- AO or AB or BO
plus factor will depend upon enzyme presence.
If a person is having both anti-A and anti-B antibodies in blood then the possible blood group of that individual can be O. However, Rh factor cannot be determined by this information.
What is Blood Group?Blood grouping is the system of classification of blood on the basis of antibodies and antigens in blood which are inherited substances present on the surface of the red blood cells.
Blood groups are classified into four types. These are A, B, AB and O. Blood group A has antigens A on the RBCs with anti-B antibodies present in the plasma. Blood group B has B antigens on RBCs with anti-A antibodies in the plasma. Blood group O has no antigens on the membrane of RBCs and antibodies of both types anti-A and anti-B antibodies in the plasma. Blood group AB has both A and B antigens, but no antibodies in the plasma.

How can you tell the difference between alternate and opposite leaf arrangements?
They are based on based whether the leaf pinnate or palmate venation.
They are based on based whether the leaf has one or two leaves at the node.
They are based on based whether the leaf has a smooth or toothed margin.
They are based on whether the leaf is simple or compound.
Answer:
They are based on based whether the leaf has one or two leaves at the node.
Explanation:
Answer: They are based on based whether the leaf has one or two leaves at the node.
Explanation: You can tell the difference between alternate and opposite leaf arrangements based on whether the leaf has one or two leaves at the node. Alternate leaf arrangement is when a single leaf is attached at one location on the stem, the node, in an alternating pattern. On the other hand, the opposite leaf arrangement is when two leaves are attached to the same node on opposite sides of the stem.

Importance of mitosis, two reasons and 300 words.
Answer: Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.
1. Development and growth
After meiosis has produced a gamete, and this has fused with another gamete to form an embryo, the embryo grows using mitosis. This growth continues throughout an organism’s life, in plants, animals, and fungi. In this way, the original chromosomal set is preserved.
2. Cell replacement
This occurs when the original cell is damaged or wounded. New cells are created to replace those that were damaged. Examples of this are the healing of a cut or a broken bone. When old cells die, new ones replace them to ensure continuing functionality.
3. Asexual reproduction
Single-celled organisms and certain multicellular organisms use mitosis for asexual reproduction. This includes reproduction by fragmentation, as in the case of planaria, and reproduction by budding, as in the case of sea anemones. Many plants reproduce using mitosis.
First, we need to understand what meiosis is. Meiosis is the replication of cells that results in each daughter nucleus containing half of the parent cell’s chromosomes. Meiosis is used primarily for the production of gametes, which are incorporated in sexual reproduction. Thus, the main difference between mitosis and meiosis is that mitosis produces somatic (body) cells, which can go on to become part of any bodily tissue, whereas meiosis only produces germ (sex) cells. Organisms which reproduce asexually cannot undergo meiosis, whereas all eukaryotic organisms undergo mitosis. Mitosis and meiosis are similar in that both can only occur in eukaryotic cells. This is because prokaryotic cells do not contain a nucleus within which to begin the processes of mitosis and meiosis. Instead, prokaryotes replicate themselves using binary fission. Both mitosis and meiosis begin with DNA replication in the parent cell to create four sets of chromosomes: in mitosis, these sets are split to form two diploid daughter cells, while in meiosis, these sets are split to form four haploid daughter cells. This is because cells undergo only one division in mitosis, whereas they undergo two divisions in meiosis.

Answer:
in an understanding of the molecules within cells and of the interactions between cells that allow construction of multicellular organisms. The more we learn about the structure, function, and development of different organisms, the more we recognize that all life processes exhibit remarkable similarities. Molecular Cell Biology concentrates on the macromolecules and reactions studied by biochemists, the processes described by cell biologists, and the gene control pathways identified by molecular biologists and geneticists. In this millennium, two gathering forces will reshape molecular cell biology: genomics, the complete DNA sequence of many organisms, and proteomics, a knowledge of all the possible shapes and functions that proteins employ.

4. Which is a factor that keeps Earth in orbit around
the Sun?
A. the gravitational pull of the Sun
B. the orbital path of the moon
C. the continuous motion of the universe
D. Earth's changing speed and direction
Answer: A. the gravitational pull of the Sun
The sun is providing a centripetal force pulling the earth inward toward the sun. At the same time, the inertia of the earth is making it want to move forward in a straight line. The two forces work together to create the net effect of the earth orbiting around the sun. Other planets, moons, asteroids, and celestial objects exert gravitational forces on the earth as well, but nowhere near the amount of what the sun does.

If the resulting F1 rabbits are crossed, what proportion of the F2 offspring will have the Himalayan phenotype and what causes the hypomorphic ch allele to be unstable and result in the distinctive fur pattern
Answer:
3/4; temperature
Explanation:
When animal are crossed to produce a different hybrid having the features or characteristics of both the two crossed animal, a hybrid offspring is produced. The hybrid offspring have all the qualities and characteristics of the parents.
When a parental cross is done between rabbit with albino rabbit, having genotype cc and with Himalayan phenotype that have a genotype of chch, it results in the production of F1 rabbits having all the Himalayan phenotype.
And if the F1 rabbits are now crossed, three-fourth of the F2 offspring have the Himalayan phenotype. The distinctive fur pattern and the unstable allele of hypomorphic ch is caused by the temperature of the surrounding.
