Answer:

Both biotic and abiotic factors affect the survival and reproductive success rate of fishes in an ecosystem.

The number of predators that a particular type of fish will have will influence the survival and reproductive rate of that fish. An increased number of predators will mean that the fishes will not be able to survive in that ecosystem and will be eaten up.

The number of preys will also affect the survival rate of fishes in an environment. The lesser the number of preys, the more the competition for food among species.

Abiotic factors like the concentration of salts in water will also influence the survival and reproduction of fishes. If a fish is not adapted to live in saline water conditions, then accumulation of salts in the ecosystem might destroy the whole fish species in that ecosystem.

Human activities, like the throwing of wastes into the aquatic ecosystem, drainage of fertilizers in the aquatic system can also destroy the survival and reproduction rate of a particular kind of aquatic animal species.

Compare and contrast the differences between mature human eggs and sperm in the following questions. For each prompt, determine
Llana [10]

Answer:

QUESTION 1:

a. They undergo unequal cytoplasmic division during meiosis- eggs

b. Their chromosomes have undergone genetic recombination and independent assortment- both gamete types

c. They contain specialized secretory vesicles called cortical granules just under the plasma membrane- eggs

d. They are characterized by a flagellum. Most of these gametes die without ever completing meiosis- sperm

e. The acrosomal reaction occurs in these cells- sperm

f. They can be derived from any adult cell type- neither gametes

QUESTION 2:

c) The egg is surrounded by a mineralized shell added before the egg exits the body.

Explanation:

a) Female reproductive cells undergo meiosis to produce one large egg and three polar bodies. However, an unequal cytoplasmic division occurs in favour of the large egg.

b) Since both egg cell and sperm cell are produced via meiosis and meiotic division involves the processes of genetic recombination and independent assortment, hence, both gamete types have their chromosomes underg genetic recombination and independent assortment.

c) Egg cells contain specialized secretory vesicles called cortical granules just under the plasma membrane. This cortical granules help prevent more sperms from fertilizing the same egg after it has been fertilized.

d) Sperm cells possess flagellum for motility in the female reproductive tract. Most of the sperm cells die without ever completing meiosis.

e) Sperm cells possess an head-covering structure called ACROSOME. Acrosome reaction is the process undergone by sperm cells permeate the zona pellucida of the egg.

f) Gametes are specifically derived from adult reproductive cells and hence, NEITHER TYPE OF GAMETE can be derived from any adult cell type

QUESTION 2:

The egg in Sea urchins is surrounded by a mineralized shell added before the egg exits the body to the external environment. This does not occur in the humans because the egg does not leave the body but fertilized internally.

The fact that plants can be cloned from somatic cells demonstrates that _____.A) differentiated cells retain all the genes of th
mojhsa [17]

Answer:

The correct answer is A) differentiated cells retain all the genes of the zygote

Explanation:

A plant can be cloned from the somatic cells which shows that the differentiated cell of plants have the ability to divide and differentiate to produce a new plant. This property of the cell is called totipotency.

All the cells in plants are not totipotent but some cells under proper condition can show the property of totipotency. Totipotency property shows that the differentiated cell is having all the genes that were present in the zygote.

This property of plant cells is used by scientist in plant tissue culture to produce plants for research and other purposes. So the right answer is A.
