Answer:
They largely depend on it for survival as meerkats are omnivores.
Explanation:
The combined effects of hotter and drier summers and fewer plants would threaten the persistence of the meerkat population. Since they eat plants and other living bugs that usually hang out in plant-abundant areas, their [meerkats] survival depends on the range of plants near them.
The natural blind spot is due to lack of receptors where the optic nerve and blood vessels leave the eye. There can also be artificial blind spots when something blocks light from reaching the photoreceptors, or when there is local adaptation of the retina as just after seeing a bright light
The statement presented above is true.
Humans form gametes or reproductive cells in a process called gametogenesis.
During this process, a diploid cell (cell containing two sets of chromosomes) goes through a meiotic division, resulting in 4 haploid germ cells ( cells containing only one set of chromosomes) called gametes.
Answer:
a) Total of ATP produced in glycolysis is equal to 2
ATP produced:
i) 1,3‑bisphosphoglycerate → 3‑phosphoglycerate (2 ATP are produced)
ii) phosphoenolpyruvate→pyruvate (2 ATP are produced)
b) 26 pyruvate molecules.
Explanation:
a) Glycolysis consists of two steps in which ATP is consumed and two steps in which ATP is released.
ATP produced = 4
ATP consumed = 2
The total of ATP produced in glycolysis is equal to 2 (4-2)
ATP produced:
i) 1,3‑bisphosphoglycerate → 3‑phosphoglycerate (2 ATP are produced)
ii) phosphoenolpyruvate → pyruvate (2 ATP are produced)
b) In the sixth step of glycolysis, inorganic phosphate molecules are consumed:
glyceraldehyde-3‑phosphate → 1,3‑bisphosphoglycerate
2 pi are added in glycolysis. As each glucose molecule undergoes glycolysis, the pi required by the 13 glocosa molecules is 26 (13 * 2). Glycolysis of each glucose produces 3 pyruvates, so 13 glucose molecules will produce 26 pyruvate molecules.
Answer:
"The combination of sex chromosomes received from parents " .
Explanation:
Sex determination : The process by which sex of a child is determined .
Parental generation :
Mother Father
XX XY (sex chromosomes )
X,X X,Y (gametes )
First filial generation :
X Y
X XX XY
X XX XY
If XX is formed then it is girl and if XY is formed then it is boy .
Conclusion :
- we concluded that there is 50-50 percent chance of boy or a girl .
- Sex of a child is determined by father because father produce different gametes .
