Hormone therapy reduces the interaction of hormones with __________.a. 6y cells
b. antigens
c. vaccines
d. cancer cells

Answers

Answer 1
Answer: The answer is d. cancer cells.

In hormone therapy for cancer cells, exogenous hormones are injected. These hormones are called anti-hormones and their purpose is to reduce the interaction of body's hormones with cancer cells. They can reduce the level or inhibit the activity of some hormones that help cancer cells to grow. This way, anti-hormones reduce the ability of cancer cells to use body's hormones and their growth is affected.

The process in which two gametes fuse to make one cell is called _____.asexual reproduction
fertilization
conjugation
pollination

Answers

The answer is fertilization.


Fertilization is the process in which two gametes fuse to creates one cell. In this process male sperm fuses with female egg which creates a zygote. 

Asexual reproduction involves the formation of offsprings without gamete fusion. Conjugation is a process of exchange genetic material between bacteria. Pollination is a process of transfer pollen to the female reproductive structures in plants, which enables fertilization.

Answer:

The answer is fertilization.

By 1500, what was the dominant religion in West Africa?

Answers

Answer:

Islam was the dominant religion in West Africa in 1500.

Explanation:

  • From 639-708 C.E, Arab Muslims captured North-Africa.
  • Arab Muslims want to bring Islam to west Africa too, but they knew it would be quite hard to cross the Sahara desert.
  • Islam soon reached Ghana through Muslim missionaries and traders.
  • Ghana's king did not convert to Islam but he allowed Muslims to build homes and mosques within his kingdom.
  • Muslim merchants and traders colonized in "Kumbi" which were the huge market place of the time.
  • soon the Muslim community grew and they had 12 mosques.

Islam is the predominant religion of theWest African interior and the far west coast of the continent (70% ofWest Africans); and was introduced to the region by traders in the 9thcentury. Islam is the religion of the region's biggest ethnic groups by population.

Jeff is studying the rate of population growth in bacteria that depend on limited resources. In his experiment, he uses two lima beans and water to make a culture. He records the number of bacteria in the culture every five days. Jeff analyzes the data after 30 days and concludes that bacterial growth is reduced when available resources start depleting.

Which statement regarding genes and evolution is true?A. If an organism has a mutation, it will be less "fit" (less able to reproduce) than other organisms.
B. Today's plethora of microorganisms is the result of an extremely brief period of genetic recombination events.
C. Mutations function to prevent the offspring of an organism from evolving.
D. Random, heritable genetic mutations are a source of genetic variation. This variation is necessary for natural selection to occur.

Answers

The statement which is true regarding genes and evolution is as follows:

  • Random, heritable genetic mutations are a source of genetic variation. This variation is necessary for natural selection to occur.

Thus, the correct option is D.

What is Genetic mutation?

Genetic mutation may be defined as sudden, stable, and inheritable alterations in the genetic material of an organism. It is considered one of the most useful events for evolution to occur.

Random mutation takes time but they are the least effective and non-influential. Such type of mutations are easily heritable and induces genetic variation among individuals of the same species.

As a result of this, as time passes such mutations become a base for natural selection to occur and allow the favorable variation to survive and reproduce effectively.

Therefore, the correct option for this question is D.

Explanation:

What would most likely occur over time if new technologies gave us information that challenged what scientists currently understand about natural selection

Answers

Question options:

A new scientific law would be established and proven by the findings. A new scientific theory would be established and proven by the findings. A current scientific law would be revised based on the new findings. A current scientific theory would be revised based on the new findings.

Answer:

A current scientific theory would be revised based on the new findings.

Explanation:

If new findings came about and challenged the current theory of natural selection so that Darwin's theory didn't look like it was true at all, the initial theory(darwin's theory of natural selection) would not be entirely discarded but revised according to these new findings and then form a sort of backbone to this new theory which would be based on findings of many independent researchers and not just one. Example: how some of Sigmund Freud's theories or Aristotle's may not be entirely valid today but still works as a fundamental for understanding other theories.
