I

Answers

Answer 1
Pure water is supposed to have a pH very close to 7,solutions with a ph of less than 7 are acidic and solutions with a ph greater than 7 are basic ,ph can have an effect on the growth of growing organisms such as brine shrimp,eggs can last years on dry land but when added to water they hatch within 12hrs.

Answers

Answer:

it is a

Explanation:

i did the test

A farmer has decided to dig an artesian well into the unconfined aquifer below his crops. His well is not working because an artesian well needs the pressure of a confined aquifer. The correct option is A.

What is an aquifer?

An artesian well is a deep tube well drilled underground to gather water for human usage. This good type is found in restricted aquifers.

The artesian well differs from the others in that it does not require the use of a pump to raise the water, as the cistern does. The sort of subsurface reservoir causes the water that travels through the tube to naturally spurt to the surface.

The underground reservoir with the qualities required for drilling an artesian well is the product of extremely specialized geological conditions. Gushing wells are caused by the restricted aquifer, as this sort of deep groundwater is known. This type of reservoir is found between impermeable subsurface layers.

Therefore, the correct option is A. An artesian well needs the pressure of a confined aquifer.

Which of the following base pairs would be found in a cell

Answers

adenine, thymine, guanine, and cytosine

adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.

The base pair cytosine and guanine is found in the cell. The correct option is D.

What are base pairs?

A base pair is a primary component of double-stranded nucleic acids that comprises two nucleobases that are hydrogen-bonded to one another.

They are the foundations of the DNA double helix and make a contribution to both DNA and RNA's folded structure.

Purines and pyrimidines are nitrogen bases that form hydrogen bonds between DNA strands.

Predicated by Chargaff's Rule, they associate together via complementary pairing A::T and G::C. The purines in DNA are the same as those in RNA: adenine and guanine.

The 2 significant pyrimidine bases in DNA are cytosine and thymine, which base pair with guanine and adenine. Uracil supplants thymine and base pairs to adenine in RNA.

Thus, the correct option is D.

Some organisms, such as bacteria, reproduce asexually; whereas, other organisms reproduce
sexually. Which statement correctly states why one type of reproduction is beneficial over the
other?
A. Asexually reproduced offspring are more genetically diverse.
B. Asexual reproduction produces offspring genetically different from parents.
C. Sexual reproduction can produce a large number of offspring very quickly.
D. Sexual reproduction produces organisms that are genetically diverse.

Answers

Answer:D

Explanation: A isn't right because during asexual reproduction there is no exchange of genetic characteristics thus the offsprings retain the genetic characteristics of their parents and there is no diversity.

Sexual reproduction on the other hand involves the fusion of gametes and the exchange of genetic characteristics thus the offsprings are diverse and are not identical to their parents as is the contrary in asexual reproduction.

Sexual reproduction produces organisms that are genetically diverse.

Sexual reproduction involves the combination of chromosomes from both parents. This combination of chromosomes introduces variation into the population. This combination does not occur in asexual reproduction.

Hence, the statement that correctly states why one type of reproduction is beneficial over the  other is that sexual reproduction produces organisms that are genetically diverse.

Often in laboratory experiments you will want to amplify regions of the genome from several different preparations of gDNA. To do this, a mastermix will be created with all the common reagents to ensure easier pipetting, proper mixing, and controlling for variations in pipetting. Create a mastermix for running 8 identical reactions, including one negative control, each with different gDNA templates (7 total gDNA templates).

Answers

Answer:

Mastermix in PCR helps in providing faster and easier setup with pipetting, proper mixing, reduction in contamination and controlling fir variation in pipeting or tube to tube variability. Contents of PCR master mix for the desired reaction are as follows:

dNTPsPrimersthermostable DNA polymerasecofactor (MgCl2)Template DNA (for 7 samples)PCR-grade water

The only difference in negative control for the PCR master mix is template or the different primer rest the components are the same in the master mix.
