Answer: The CARRYING CAPACITY of a particular population in an ecosystem is defined as the maximum population size that the environment can support indefinitely.

Explanation:

Population size is important as it affects the survival of a given species in a habitat. A small population may be easily wiped out by events such as fires, diseases, unfavorable climatic changes and so on. A large population stands a better chance of surviving dangers and unfavorable conditions.

The carrying capacity of a population in an ecosystem can show some changes due to the following factors:

--> migration of organisms to other habitats

--> invasion or colonization by new species and

--> increase or decrease in birth rates and death rates.

These factors operate during:

--> seasonal climatic changes,

--> changes in food availablity,

--> breeding periods and

--> unfavorable natural events such as fires and droughts.

A man who has type B blood has children with a woman who has type A blood. A. If they are both heterozygous for this trait, pred
Ivenika [448]

Answer:

The possible blood types of their children are: type AB (iAiB), type A (iAi), type B (iBi), type O (ii)

Explanation:

Blood type in humans is controlled by a gene with multiple alleles. Alleles iA and iB are dominant over allele i but co-dominant. The following blood types are encoded by the following alleles:

Blood type AB - iAiB

Blood type A - iAiA or iAi

Blood type B - iBiB or iBi

Blood type O - ii

According to this question, a man who has type B blood has children with a woman who has type A blood. They are both heterozygous, meaning that the man's genotype is "iBi" while the woman's genotype is "iAi". Both parents will produce gametes as follows:

iBi = iB and i

iAi = iA and I

Using these gametes in a punnet square (see attached image), the following possible blood types are produced in the offsprings:

- type AB (iAiB)

- type A (iAi)

- type B (iBi)

- type O (ii)

Do research about new hypothesis that has replaced an older explanation of something in the natural world
Gre4nikov [31]
I believe that what is meant with the phrase "older explanation" is none other that superstition. Therefore, I will give you one superstitious belief which is now explained by science.

In Southeast Asia, people used to believe that St. Elmo's fire appears in remote areas because a bloody battle occured in that place leaving disembodied souls of the dead wandering there in the night and even in sunshine!

For generations, many people believed that this is a fact and some even say that these apparitions are diabolical or demonic in nature. So often, caution is advised to people whenever a ball of fire appears out in the open. 

However, recent breakthroughs in the 21st century helped scientists to explain this mysterious phenomena. They found out that St. Elmo's fire is actually plasma, nothing special. Now, plasma is considered one of the states of matter! But mind you, it still does not explain why St. Elmo's fire seems to have a mind of its own!
