Answer:
The correct options is B.
Explanation:
Evolution has to do with the changes that occur in a particular population of organism as a results of environmental changes and other pressure that the population is exposed to and how the organism adapt to counter the changes.
Out of all the options given in this question, the individual that is most likely to be successful in an evolutionary sense is the one describe in option B. This is because, the organism has a short life span of five days and it left behind ten children that are capable of reproducing. Evolution is a process that occur over a long period of time. So, if it an environmental change occur in the environment where the organism lives, it will be easier for the new generation and the subsequent generations of the organism to adapt to the change.
Those organisms that have long life span will not be able to adapt as easily as the organisms in options B because it will take many years and many generations for them to do that.
Answer:
The correct answer is option - d. Production of primary spermatocytes.
Explanation:
The accessory cells or supporting cells present within the seminiferous tubules of reproductive system termed as the Sertoli cells. They play various roles in the body and reproductive system.
Sertoli cells make blood-testis barrier in adjacent Sertoli cells in the seminiferous tubules. These cells secrete different types of enzymes and hormones such as inhibin which are also secreted by ovary and placenta in females. Sertoli cells produce seminiferous tubular fluid to provide nutrition to the sperm. Apoptotic germ cells are timely eliminated by these cells.
Thus, the correct answer is option D. Production of primary spermatocytes.
Answer:
11.) red aka b
12.)orange aka a
13.)yellow aka c
14.) orange aka b
15.) last one aka c
Explanation:
11.) F=ma---> 75=0.445(a)--->a=168.5m/s^2
12.)F=ma---> 5,100=m(3)---->m=1,700kg
13.)F=ma---> 3.63=18.15(a)--->a=0.2m/s^2
14.)F=ma---->F=(2,030,000)(15)----->F=30,450,000n
15.) Doubling the mass doubles the acceleration
It is endangered? Because a kirtland warbler is a big species.
The temperate coniferous forest contains tress which have adapted to have very thick bar, like evergreen trees. I might be wrong, but that is what I think.
