Among 1,000 gametes produced by a plant of genotype o ci +/+ + p, what types of gametes would be expected, and what number would be expected of each? Assume that the chromosome interference across this region is 80%.
Answers
Answer:
Expected gametes : o+ ci+ p+,o- ci- pi-, o+ci- pi+,o- ci+ pi-, o+ci+ pi-, o- ci- pi+
Explanation:
Genetic distance between genes is equal to the recombination frequency, so the total number of recombinant gametes can find out by multiplying the recombination frequency of both sides to the total number of gametes.
Interference= .80;
Coefficient of incidence
= 1 - 0.80
= 0.20
15cM = 15% recombination,
20cM = 20% recombination.
Then, Number of recombinant offspring
= 15 x1000/100
= 150,
Gametes expected= o+ ci+ p+,o- ci- pi-, o+ci- pi+,o- ci+ pi-, o+ci+ pi-, o- ci- pi+

Two populations have been geographically isolated from each other for many generations.
Which statement is most likely correct about the two populations?
O They can still produce viable offspring with each other.
O They can't reproduce with each other.
O They look very similar to each other.
O Their gene pools are highly similar.
Answers
Answer:
The most likely correct statement about the two populations that have been geographically isolated from each other for many generations is "Their gene pools are highly dissimilar."
When populations are geographically isolated from each other, they are unable to interbreed, therefore, they evolve independently from each other. Over time, different selection pressures and mutations cause genetic differences to accumulate between the two populations. These genetic differences will become evident when the two populations are brought back together. If the genetic differences are large enough, the two populations may no longer be able to interbreed and produce viable offspring.

Answers
Several conditions make our planet earth unique, to answer this statement we need to understand that.....
Earth is uniqueThere are many planets in the solar system, however, none have a location like planet Earth. Our planet is in a privileged condition, as it is located at a distance from the sun that does not prevent the emergence of elements essential for sustaining life, that is to say, it is not very close, a fact that would raise temperatures, and very far away, when they would be very low, hindering the development of lives. This factor was decisive for the formation of liquid water on planet Earth, since it is the only one with such a resource in the solar system.
With this information we can come to the conclusion that the statement is correct, the stability of the earth and location in the solar system, provided that the earth could have water in a liquid state.

Answers
Answer:
The correct answer is - red light.
Explanation:
Plants absorbed white light best than any other light, however, red light is better light than other lights after the white light due to its long wavelength and the right amount of energy to excite or stimulate the electrons of the light center of the chlorophyll and transit to a higher energy level which increases the rate of photosynthesis.
Red light is a light with a longer wavelength which helps in radiate and heat the chlorophyll than its counterpart. A high rate of photosynthesis results in more glucose production.

Answer:
The order of the bases on the opposite strand of DNA should be Thymine, Guanine, Guanine and Cytosine.
DNA and complementary base pairing
The deoxyribonucleic acid (DNA) is a double helix composed of two long chains of sequential nucleotides.
In DNA there are four classes of nucleotides, each containing one different nitrogenous base (i.e., Adenine, Guanine, Cytosine, Thymine).
According to the base pair rules of complementarity, Adenine always pairs with Thymine, whereas Guanine always pairs with Cytosine.
In conclusion, the order of the bases on the opposite strand of DNA should be Thymine, Guanine, Guanine and Cytosine.

A 56-year-old man with an insufficient aortic valve is scheduled for surgery. Identify the chamber of the heart that the regurgitated blood most likely enter. Will the blood regurgitated primarily during systole or diastole?
Answers
Answerand Explanation:
The regurgitated blood will enter the left chamber of the heart. This is because as the patient's aotic valve is not working properly, it does not close properly, which allows a backflow of blood to occur towards the left chamber of the heart, as this chamber relaxes to be filled with blood pumped by the right camera.
As the regurgitated blood is a pumped blood, we can consider that it will happen, mainly during systole, which is the moment when the heart contracts to pump blood. This contraction will be made with the malfunction of the aortic valve which will cause blood regurgitation.

Answers
Answer:
False
Explanation:
each enzyme works on one particular substrate :)
Answer:
False
Explanation:
Enzymes can only react with one different substance because they are very specific.
They have an active site which makes them specific, because this active site restricts which substrates (reactants) can bind to the enzyme.
So, this statement is false, because enzymes can only react with one substance since they are specific.

Answers
The correct answer is 1) Evolutionary
Explanation:
The "good genes hypothesis" argues traits of the opposite sex that are considered as positive or attractive reflect evolutionary traits and therefore are indicators of a better-quality mate. Indeed, this theory argues attraction is connected to better chances of survival or better chances to reproduce. This belongs to the evolutionary approach in psychology because these "attractive" traits are the result of evolution because only the "fittest" individuals reproduce and their genes prevail over time.

Answers
The options are;
A) biology; theory of relativity
B) geology; theory of continental drift
C) ecology; discovering new elements
D) astronomy; developing quantum mechanics
Answer:
B) geology; theory of continental drift
Explanation:
Looking at the options;
-theory of relativity is a topic in physics originated by Einstein. Thus, it is matched to physics and not biology.
- theory of continental drifts are related to plate tectonics where it explains how continents shift position on Earth's surface. This is a branch of Geography and is thus correctly matched.
- discovering new elements is a topic under chemistry and not ecology. Thus, this is not matched correctly.
-developing quantum mechanics is a topic in physics that deals with the relationship between energy and matterwith respect to atomic and subatomic scale. Thus, it is not well matched.

How many moles of NaCl do you have if you have 0.5 g of NaCl ?
Answers
Answer:
0.0085 moles
Explanation:
To determine the number of moles of NaCl in 0.5 g, you need to divide the mass by the molar mass of NaCl. The molar mass of NaCl is the sum of the atomic masses of its constituent elements, which are sodium (Na) and chlorine (Cl).
The atomic masses of Na and Cl are 22.99 g/mol and 35.45 g/mol, respectively. The molar mass of NaCl is therefore:
Na = 22.99 g/mol
Cl = 35.45 g/mol
NaCl = Na + Cl = 22.99 g/mol + 35.45 g/mol = 58.44 g/mol
To calculate the number of moles of NaCl in 0.5 g, we use the formula:
moles = mass / molar mass
Substituting the values, we get:
moles = 0.5 g / 58.44 g/mol ≈ 0.0085 mol
Therefore, 0.5 g of NaCl is equivalent to approximately 0.0085 moles of NaCl.

. What is the heart's role in the circulatory system?
Answers
The only organ present in the circulatory system is the heart. The blood from the heart goes to the lungs in order to get oxygen. The muscle present in the inner part of the system is the one responsible for the pumping of blood throughout the body when the heart beats. The blood involve in this process is the one that carries the oxygen and nutrients to the rest of the body. It also carries CO2 and waste products. The main role of the heart is to carry oxygen to every cell of the body. It also pumps blood throughout the body helping it to control the heart rate and blood pressure.
What happens on a cellular level during a organ rejection? Simplified.
Answers
Organ rejection takes place when your body is subjected to a new organ which is a foreign object and attacks it.
What do you mean by Graft rejection?Graft rejection may be defined as a process in which a transplant recipient's immune system attacks the transplanted organ or tissue.
Xenograft shows high rejection. This is because it involves the transplantation between genetically distinct members of different species.
The process of organ rejection is initiated by T cells which perform the role of the recognization of a transplanted organ.
If these T cells are activated, it may lead to organ rejection by undergoing clonal expansion, and differentiation of the effector cells, which together lead to the obliteration of the tissues.
Therefore, organ rejection takes place when your body is subjected to a new organ which is a foreign object, and attacks it.
