Answer:

The correct answer is- law of independent assortment

Explanation:

Law of independent assortment says that assortment of one gene pair is independent of assortment of other gene pair which means each contrasting gene pair bears no association with other pairs of contrasting character and behave and segregate independently.

This allows the combination of new characters in the offspring. So it helps in increasing the genetic variability in the gene pool. Therefore law of independent assortment tells that inheritance of one trait had no effect on the inheritance of another.

A population of kangaroos is growing at a rate of 2% per year, compounded continuously. If the growth rate continues, how many y

antoniya [11.8K]

Answer:

The correct answer is 20 years.

Explanation:

It is given that the growing rate is 2% or 2/100 = 0.02

This rate got increased to 150%

The formula for exponential growth is:

A = Pe^rt

Let the initial population be 100%

150 = 100.e^0.02*t

3/2 = e^0.02t

1.5 = e^0.02t

After taking log from both the sides:

ln(1.5) = 0.02t * ln(e) [ln(e) = 1]

ln(1.5) = 0.02t

t = ln(1.5)/0.02

t = 20.27

Thus, it will take around 20 years for the size of the population to reach 150 percent of its present size on the basis of the exponential growth function.

How does the rules of atoms apply to the conservation of mass?

Alchen [17]

Answer:

The Law of Conservation of Mass tells us that matter is neither created nor destroyed during a chemical reaction. Atoms can be rearranged to form new compounds, but the total mass of the system remains constant.

Describe the changes that take place during the menstrual cycle from Day 5-13 to the following:

erastovalidia [21]

Answer:

Between days 5 and 13 of a woman's menstrual cycle, an unfertilized egg in ovary prepares its development and maturation within the follicle, while the lining of the uterus -the endometrium- progressively enlarges.

Explanation:

Under normal conditions, a woman's menstrual cycle lasts 28 to 30 days, during which time both hormonal and physiological changes occur as part of the reproductive process.

Menstruation occurs as a result of the shedding of the endometrium, which had previously developed to facilitate the implantation of a possible pregnancy. This phase usually lasts five days and is characterized by genital bleeding.

From the fifth to the 13th day, a woman's reproductive system undergoes changes in preparation for possible fertilization and pregnancy:

The unfertilized egg is found inside the ovarian follicle, maturing before its imminent release, under the influence of follicle-stimulating hormone (FSH). The maturation of a few follicles occurs simultaneously, but only one will reach the necessary maturity to allow the release of the egg.
The lining of the uterus, called the endometrium, receives signals from the hormone estradiol -produced by the mature ovarian follicle- and induces proliferation and thickening of the endometrium.

Approximately on the 15th day of the menstrual cycle, the egg is released and it is the time when it can be fertilized by a sperm to produce the zygote, which will start a pregnancy in women.

Smilin is a (hypothetical) protein that causes people to be happy. It is inactive in many chronically unhappy people. The mRNA i

Studentka2010 [4]

Answer:

The single nucleotide mutation affects the splicing of the mRNA molecule of Smilin in unhappy people. This with result in a truncated protein lacking part of it amino acidic chain

Explanation:

It's true that the information of aminoacids that form the proteins is codified on the exons, but introns also have important information, for example, the sequences related to the splicing of the mRNA exons.

Briefly, during the splicing process, the introns are removed, leaving the mRNA that is going to be translated (there could be also other post translational modifications before going to ribosomes).

Also, there's different ways to splice the different exons. For example, let's say a mRNA has four exons, so the mature mRNA could have exons 1-2-3-4, or 1-2-4, or 1-2-3, it depends on the location of the splicing signals. This are called splicing alternatives, so the same original mRNA can give arise to different forms of a protein.

In the particular case of Smilin, apparently the DNA has a single mutation in the intron for the mRNA of the protein. Despite it might seem as a minor difference, it causes the final mRNA (the one that is translated) to lose an internal stretch of 173 nucleotides.

A possible explanation is that this single mutation is affecting a splicing signaling sequence, making the splicing complexes skip one exon. Again, if we imagine that the original protein has four exons, this means that the happy people has an mRNA with all the exons, while unhappy people is lacking one.

As a result, the protein Smilin will be lacking part of its internal region. The actual effects this has on the protein function will depend on the role of the deleted section.
