Answer:
1) the genes and chromosomes do not double after each generations because parental sex cells are haploid and only contain one set of chromosomes. During fertilization the two cells fuse to form a diploid zygote with two copies of genes and chromosomes. For example a normal human has 46 chromosomes (2 copies of 23 chromosomes) during reproduction gametes which contain 23 chromosomes (haploid) fuse to form an offspring with the correct number of chromosomes ( 23 + 23 = 46).
2) offspring only receive one set of chromosomes from each parent so to maintain the chromosome number of humans. If this did not happen you would not be the same species.
C. Vegetation
because even though cows are important, all life is and not just that species and then cars and factories are unnatural and would not be critical for the carbon cycle in nature.
As seen in the video game death stranding.
Two extinction level events happened and wiped out half of all human life. Building and cars and homes were destroyed and replaced by growling grass or dirt. A new species of bug came about called a cryptobite and a bridge was formed between the world of living and dead and hence forth came the rise of beached things
Answer: a. endoderm-bone
Explanation: In the context of embryonic development, bone tissue may arise from several precursor cell populations, such as the neural crest (some facial bones), lateral mesoderm (bones of the limbs, among others), and paraxial mesoderm (vertebrae and part of the skull). There is no evidence to suggest that any of the bony structures is derived from the endoderm germ layer.

Endoplasmic reticulum is situated close to the nucleus and is involved
in protein synthesis. Rough ER has lysosomes around the edges.
Lysosomes - The cleaner of the cell. Small and numerous, increases
surface area and increases the rate at which waste products are removed
from the cell.
Chloroplasts - Made up of Grana, stacked up to increase surface area.
This allows more Chlorophyll to be made to increase the rate of
photosynthesis.
Nucleus - Information point of the cell</span>
