Four major components of biodiversity are:

1. Genetic diversity - refers to the genetic variation that occurs among members of the same species.

2. Species diversity - (taxonomic diversity) refers to the variety of species or other taxonomic groups in an ecosystem

3. Ecosystem diversity - refers to the variety of biological communities found on earth. With ecosystem diversity, its two levels are generally considered, which are communities and ecosystems.

4. Functional diversity - refers to the variety of biological processes, function or characteristics of a particular ecosystem.

Answer:

a. conservative replication

b. semi conservative replication

c. dispersive replication

d. discontinuous replication

e. continuous replication

The CORRECT ANSWER IS C.

c. dispersive replication

Explanation:

The attached image shows a single band that becomes lighter (in volume) and increase in darker intensity (in times of color) is revealed with consecutive replications. The major pattern that would produce these outcome is dispersive replication.

Conservative replication do reveal two bands (a 14N for the wholly latest molecule, and a 15N for the totally antiquated molecule) after the initial replication. Therefore, this wholly wrong.

Semi-conservative replication reveal an individual band of transitional weight after the initial replication, followed by two bands following the second replication (one of transitional weight, and the other at the 14N position). These two bands is observed in each following replication, with the transitional weight becoming lighter in color as the 14N band is seen to appear darker in color.

The real pattern gives an individual band that pinpoints to all molecules in an individual replicative cycle possessing the same constituents.

Dispersive replication, has its molecules to be a blend of old (15N) and new (14N) strands. Each replication raises the ratio of new to old strands as it explains the reason an individual band is shown raised (lighter in weight) with every replication.

Answer:

Given that,

$Distance=360\:Kilometres$

$Speed = 720 KM/hr$

$time=360km/720kmh^{-1}$

$time=1/5 hr$

$Time = 30\: minutes \:or \:1/5 \:hours \: or \: 0.5 \:hours.$

In garden peas a pure line that is tall with purple flowers is crossed to another pure line that is short with white flowers. Th

defon

Answer:

See the explanation

Explanation:

Answer 1.

As given that in F1 all are short and white then it can be said according to Mendel's law that short and white are dominant over tall and purple.

Let S for short s for tall and W for white and w for purple allele.

So the genotype of short purple will be Ssww or SSww. So In first case Ssww self crossed then resultant offsprings will be,

................ Sw .................... sw

Sw ........ SSww ............. Ssww

sw ........ Ssww .............. ssww (tall and purple)

So from this 1/4 will be tall and purple while 3/4 will be short and purple.

In second case SSww only short purple progeny will appear.

Answer 2.

2. a) The female progeny will not show any trait because there are two X chromosome in females , so female offspring can be carrier but not show any trait in case of X- linked trait.

2. b) Half of male offsprings show trait because X is inherited from mother. So the chance of having X-linked recessive allele is 1/2.

2. c) The chance of having X linked affect allele in daughter is 1/2. So the chance of inheriting that X to son will be 1/2 so in total there is chance of 1/4 that son will be affected.

2. d) the chance of first child show this trait will be 1/4 in case of male offspring while 0 in case of female offspring.

Hope this helps!

Duchenne muscular dystrophy is a serious condition caused by a recessive allele of a gene on the human x chromosome. the patient

dedylja [7]

Duchenne muyscular dystrophy is caused by a mutation on the X chromosome, so a male gets it from his mother's X, if she is a carrier. The male child gets a Y and no X from his father, so the disease is always transmitted through the X from the mother. If a female gets Duchenne muscular dystrophy she has to have two X chromosomes, one from a carrier mother and another from from an affected father. This is virtually impossible because most males die before childbearing age and there is no way a female child can get an X from a man who does not live long enough to procreate. About eight percent of carrier women do show some muscle weakness, but they do not have the disease.

Dose DNA have cells i need to know for a assingment

kiruha [24]

Answer and Explanation:

Cells are made of DNA (Deoxyribonucleic Acid).

They provide the genetic instructions for making and forming a cell.

The DNA is found inside the nucleus of the cell.

Because the cell is very small, and because organisms have many DNA molecules per cell, each DNA molecule must be tightly packaged. This packaged form of the DNA is called a chromosome

DNA do NOT have cells, but cells DO have DNA.
