when a tautomeric shift occurs, what is true about the resulting mutation?

Answers

When a tautomeric shift occurs, then the resulting mutation ALWAYS changes a purine to a purine or a pyrimidine to a pyrimidine. A tautomeric shift may lead to a point mutation.

A mutation is any alteration in the nucleotide (DNA) sequence of the genome of an individual.

A tautomeric shift can be defined as a temporary change in the nucleotide base structure.

A transition mutation is a point mutation of one purine or pyrimidine base pair to the other purine/pyrimidine that occurs when one nucleotide base undergoes a tautomeric shift during DNA replication.

Frequent earthquakes in an area may indicate

Answers

Earthquakes occur along fault lines, cracks in Earth's crust where tectonic plates meet. They occur where plates are subducting, spreading, slipping, or colliding. As the plates grind together, they get stuck and pressure builds up. Finally, the pressure between the plates is so great that they break loose

Frequent earthquakes in an area indicates that there are tectonic plates boundaries and there is sudden regression of underground rocks. Through the areas when there is sudden movement and dynamic stress along with the sudden triggering.

What are tectonic plates ?

Tectonic plates are larger pieces of earth's crust  and uppermost mantle. Tectonic plates movement cause the earthquakes to occur.

The other types of earthquakes are that of volcanic earthquakes, induced earthquakes and collapse earthquakes.

Therefore, earthquakes are mainly due to various conditions and other environmental activities that are not under control.

What type of energy is used? Photosynthesis transforms ___________ energy into ___________ energy in ___________ molecules.

Answers

Answer:

Photosynthesis converts solar energy into chemical energy that plants use to make glucose so they can grow.

Explanation:

During photosynthesis, solar energy is converted into chemical energy in the form of ATP molecules.

----------------------------------------------------------------------------------------------

During photosynthesis solar energy is converted into chemical energy in the form of energy rich bond of ATP molecule.

ATP (Adenosine triphosphate) and ADP (Adenosine diphosphate) molecules are termed currency of energy. ADP molecule is converted into ATP molecules, whenever energy is available in certain exothermic reactions of metabolism.

ATP molecules are store- house of energy. ATP molecule is broken down into ADP molecule in presence of enzyme ATPase, releasing energy whenever energy is required.

The synthesis of ATP molecules, utilizing solar energy during photosynthesis, is termed photo-phosphorylation.

These ATP molecules produced during light reaction of photosynthesis are utilized in dark reaction of photosynthesis (Calvin cycle).

ATP molecules synthesized during photo-phosphorylation may also be used in other metabolic reactions.

Photo-phosphorylation is of 2 types, i.e. Cyclic and Non-cyclic photo-phosphorylation.

Chlorophyll molecules entrap solar energy . There are 2 types of photo systems in chlorophyll. These are photo-system -I and photo-system-II .

The electrons of chlorophyll molecule of photo-system I get excited which pass through series of electron carriers in electron transport system arranged in the order of decreasing energy level.

During the passage of electrons from carriers of higher energy level to the carriers of lower energy level, the energy is lost which is utilized for converting ADP molecule into ATP molecule.

Photo-system I is concerned with light reaction of photosynthesis only, constituting cyclic photo-phosphorylation.

The electron transport during Photo-system II results in the synthesis of NADPH2 in presence of enzyme NADP reductase. NADPH2 is used in reduction reaction of Calvin cycle.

Both Photo-systems participate in non-cyclic photo-phosphorylation that results in the synthesis of NADPH2 in addition to the synthesis of ATP molecules.

One way that the use of rodenticides affects the kit fox population will be a

reduction in the population.

Foxes are secondary or tertiary consumers which feeds on smaller animals

such as rodents in the ecosystem. The use of rodenticides will kill and

reduce the number of rodents available for food.

The reduction in the rodents means lesser source of food for the foxes and a

decrease in the population. The size of the kit fox population is affected

because a larger size being more affected than the ones with a smaller

Angiosperms also make up the vast majority of all plant foods we eat. (Ex. grains, vegetables, and fruits.) The angiosperms are vascular seed plants in which the ovule (egg) is fertilized and develops into a seed in an enclosed hollow ovary The ovary itself is usually enclosed in a flower, that part of the angiospermous plant that contains the male or female reproductive organs or both. fruits are derived from the maturing floral organs of the angiospermous plant and are therefore characteristic of angiosperms.

She then used 30mL of liquid to wet a paper towel and put a different paper towel in each bag.

For each offspring genotype in the Punnett square you just completed, determine the phenotype. In other words, what is the predicted fur color and eye color of the offspring? Using your Punnett square from the last step, fill in the predicted fraction for each phenotype in the data table below.

Black Fur and Black Eyes Black Fur and Red Eyes White Fur and Black Eyes White Fur and Red Eyes
Predicted Fraction
/16
/16
/16
/16

Answers

Assuming diallelic genes, expressing complete dominance and not interacting, the predicted fractions are 4/16 Black Fur, Black Eyes - 4/16 Black Fur, Red Eyes - 4/16 White Fur, Black Eyes - 4/16 White Fur, Red Eyes

Available data:

Two traits are involved in this cross  ⇒  fur color and eye color.

Black fur color is dominant over white fur color

Black eyes is dominant over red eyes

The cross is between a h0m0zyg0us recessive parent with a dihybrid one.

What can we deduct about this information?

Assuming diallelic genes coding for each trait, expressing complete dominance, and no interaction between genes, we can propose the following genotypes and phenotypes.

         Genotype                               Phenotype          

BBEE, BbEE, BBEe, BbEe        Black fur, Black eyes

bbEE, bbEe                              White fur, Black eyes

BBee, Bbee                              Black fur, Red eyes

bbee                                         White fur, Red eyes

How to perform the cross?

Cross: h0m0zyg0us recessive parent with a dihybrid parent

Parental phenotypes)    White fur, Red eyes   x   Black fur, Black eyes

Parentals genotype)    bbee     x     BbEe

Gametes)  be, be, be, be

F1)

4/16 = 1/4 = 25% of the progeny is expected to be dihybrid, BbEe, expressing black fur and black eyes

4/16 = 1/4 = 25% of the progeny is expected to be heter0zyg0us for fur color and h0m0zyg0us recessive for eye color, expressing black fur and red eyes.

 

4/16 = 1/4 = 25% of the progeny is expected to be heter0zyg0us for eye color and h0m0zyg0us recessive for fur color, expressing white fur and black eyes.

4/16 = 1/4 = 25% of the progeny is expected to be h0m0zyg0us recessive, bbee, expressing white fur and red eyes.

Answers

It has to filter out the small amount of oxygen in the water, unlike terrestrial creatures.

Photosynthesis

Explanation:

Just like trees and other plants, grass converts energy from sunlight into sugar through the process of photosynthesis. This energy is used to convert water and carbon dioxide into glucose. Carbon dioxide is absorbed through the stomata in the leaf and water is mainly derived from uptake in the roots. Photosynthesis makes the grass green and healthy.
