Mitosis makes.....
A. cell phones
B. identical body cells
C. sperm and egg cells
B. identical body cells
hope it is helpful to you
Answer:
B. identical body cells
Explanation:
Mitosis produces new cells, and replaces cells that are old, lost or damaged. In mitosis a cell divides to form two identical daughter cells. ... Mitosis separates these chromatids, so that each new cell has a copy of every chromosome.

Which statement best describes Earth's human carrying capacity?
A: It is a fixed number that we will soon exceed.
B: It is increasing due to improved technology and medicine.
C: It is decreasing due to increasing population.
D: It is decreasing due to decreasing death rates.
The statement that best describes Earth's human carrying capacity that it is increasing due to improved technology and medicine. The correct option is B.
What is carrying capacity?Carrying capacity is the amount of persons the individual may experience over a lengthy amount of time and density affects the overall population.
Food, habitat, moisture as well as other necessities found in the environment determine carrying capacity.
Carrying capacity is defined as the average population size of a species in a given habitat.
Environmental factors such as adequate food, shelter, water, and mates limit the species population size. If these needs are not met, the population will decrease until the resource rebounds.
The best description of Earth's human carrying capacity is that it is increasing as a result of improved technology and medicine.
Carrying capacity is defined as the maximum number of individuals of a population that the environment can support.
Thus, the correct option is B.

What causes the formation of a cervical plug a testorone b progesterone c luteal d estroge e follicle
Answer:
b progesterone
Explanation:
The plug is formed as soon as there is implantation of fertilized eggs. The thickness of the cervical mucus becomes different as hormone levels changes in pregnancy.
The progesterone, encourages the production of thick fluid/ mucus which brings about the formation of a plug. This prevents bacteria from getting into the uterine cavity.
Answer: The correct option is B (progesterone).
Explanation:
The cervix is the ring of muscles also called the neck of the uterus in female reproductive system. This protrudes through the anterior wall of the vagina, opening into it at the external os.
After the fertilization of the ovum by the spermatozoa, the uterus prepares for the implantation which results from the secretion of hormones. Under the influence of oetrogen, secreted by the developing follicle, the cells of the endometrium divide rapidly causing the endometrium to build up and thicken.
While the viscosity of cervical mucus changes in response to hormone levels and during pregnancy, progesterone fosters the production of highly viscous mucus resulting in the formation of a plug that forms a physical barrier to bacteria and prevents their ascension into the uterine cavity. This plug is called CERVICAL PLUG.

Anthropologist: In an experiment, two groups of undergraduates were taught how to create one of the types of stone tools that the Neanderthals made in prehistoric times. One group was taught using both demonstrations and elaborate verbal explanations, whereas the other group learned by silent example alone. The two groups showed a significant difference neither in the speed with which they acquired the toolmaking skills nor in the level of proficiency they reached. This shows that Neanderthals could just as well have created their sophisticated tools even if they had no language
Which one of the following, if true, most weakens the anthropologist's argument?
(A) Apart from the sophistication of their stone tools, there is a great deal of evidence suggesting that Neanderthals possessed some form of language.
(B) The students who were taught with verbal explanations were allowed to discuss the toolmaking techniques among themselves, whereas the students who learned by silent example were not.
(C) The tools that the undergraduates were taught to make were much simpler and easier to make than most types of tools created by Neanderthals.
(D) The instructor who taught the group of students who learned by silent example alone was much less proficient at making the stone tools than was the instructor who taught the other group of students.
(E) The tools created by Neanderthals were much less sophisticated than the tools created by anatomically modem humans who almost certainly possessed language and lived at the same time as the Neanderthals.
Answer:
A
Explanation:
The point of this arguement is that with or without speaking they were able to make the same sophisticated and complex tools, if it is true that both had a language that would mean the silent people would have no point and that both types of humans had the same initial factors.

Write a news article on your interview with Noah. (100 words or more is fine)
Need help asap just answer write the article the first 1 i already answered just copy pasted the questions
Answer:
We got a chance to speak to Noah the Ark builder. Many people of the town have been wondering what Noah has been building lately. We asked him what was his objective and he said "A great flood like no other will come, water from the sea will fall from the air. Whoever is in the ark shall be safe. Two of each type of animal on earth shall come to my ark for shelter. The storm will be so great it will knock out all who does not inhabit the ark."It is hard to understand what he means by these statements but who knows maybe his boat will take him somewhere. The people of the town have been calling him insane, since no one would need a boat that big.
(I'm guessing that you mean the interview was before the flood since everyone died after.)

How does polyploidy allow speciation to occur in a single generation? Polyploid offspring produce gametes earlier in the mating season than than their diploid parents, causing reproductive isolation between the two generations. Polyploid offspring produce smaller gametes that disperse farther than the gametes of diploid parents, causing geographic isolation between the two generations. Physiological differences between polyploid offspring and their diploid parents allow them to thrive in different environments, causing geographic isolation between the two generations. Genomic differences between polyploid offspring and their diploid parents prevent them from successfully interbreeding, causing reproductive isolation between the two generations.
Answer:
Genomic differences between polyploid offspring and their diploid parents prevent them from successfully interbreeding, causing reproductive isolation between the two generations.
Explanation:
Speciation is an ecological and biological process through which new species are formed due to isolation.
In plants, polypoidy involves the possession of two complete sets of chromosomes and it leads to the origin of new species. Also, the two sets of chromosomes comprises of triploidy (69 chromosomes) and tetraploidy (92 chromosomes).
As a result of the genomic differences between polyploid offspring and their diploid parents, this usually prevent them from successfully interbreeding and consequently causing reproductive isolation between the two generations.
