What's the role of oxygen in cellular respiration?
OA It accepts electrons and keeps the electron transport chain running.
ОВ. It breaks down carbon-based sugar molecules to release energy and forms carbon dioxide.
Ос.
It combines with hydrogen ions in sugar molecules to release energy and form water.
OD. It supplies electrons to the electron transport chain to keep it running
Answer: D
Explanation: Oxygen plays a vital role in energy production via a system called electron transport chain , which is an important component of cellular respiration. ... Oxygen acts as a final electron acceptor that helps move electrons down a chain that results in adenosine triphosphate production
Gene A is 10 mU from Gene B on chromosome 2, and the alleles are in coupling. An individual with the genotype AaBb is testcrossed. What fraction of the offspring would be expected to have genotype aabb?
The answer is supposed to be 45% but I'm unclear on how to get there. Thanks!
Answer:
Parental chromosomes A----b and a-----B when fertilized with ab will produce AabB and aaBb - these will be progeny with parental chromosome --- so no recombination.
You are told that map distance is 20cM which is also telling you that recombination frequency is 20% , so % progeny showing recombination = 20%, so % progeny not showing recombination is 100= 20 = 80%. This will be composed of the 2 parental categories, as above so % aaBb = 40%

Translate the word phrase into an algebraic equation: the quotient of 24 and 2 is equal to 12.
Answer:
24/2 = 12
Explanation:
(I'm pretty sure this isn't a Biology question, but I'll answer this because I'm nice.)
To translate English into algebriac equations, we have to understand what the symbols in algebra mean. Here are some we should know:
= : "equal to", "is", "equivalent to", etc.
> : "greater than"
< : "less than"
>= : "greater than or equal to", "at least"
<= : "less than or equal to", "at most"
We also have to know basic math operations:
a + b : "a added to b", "a plus b", "a combined with b", "a more than b", etc.
a - b : "a minus b", "b less than a", "b subtracted from a", etc.
a * b : "a multiplied by b", "a times b", "the product of a and b", etc.
a / b : "the quotient of a and b", "a divided by b", etc.
There are MUCH MORE examples of this, yet it becomes second-nature to change English sentences into algebra.
So, let's tackle the question. Sadly, it's pretty simple, so I won't really go in depth here. Since the quotient of a and b is a/b, the quotient of 24 and 2 is 24/2. We can also say that "is equal to 12" is "= 12". So,
24/2 = 12.

Write a scientific argument that addresses the question: During a year, will there be a lunar eclipse of the moon of Kepler-47c?
Answer:
The moonlight we see on Earth is sunlight reflected off the Moon's grayish-white surface. The amount of Moon we see changes over the month — lunar phases — because the Moon orbits Earth and Earth orbits the Sun. Everything is moving. During a lunar eclipse, Earth comes between the Sun and the Moon, blocking the sunlight falling on the Moon. Earth's shadow covers all or part of the lunar surface.
Explanation:
Hope this helps! :)
A year, will there be a lunar eclipse of the moon of Kepler-47c are the to occur once a year.
What is moon?The term moon relates to the spherical shape of the satellite's identity. The moon was supposed to shine in the night. It is roughly one-quarter the size of Earth. The Moon is the fifth-biggest satellite in the Solar System, bigger than any of the known planetary systems and the largest spacecraft relative to its parent planet.
Sunlight reflecting off the Moon's grayish-white surface causes the moonlight we see on Earth. So because the moon passes Earth and the Earth orbits the Sun, the amount of Moonlight we see varies over the lunar phases of the month. Everything is in motion.
During a total eclipse, Earth passes here between the Moon and the Sun obstructing sunlight from reaching the Moon. The shadow of the Earth covers all or parts of the surface of the moon.
As a result, the lunar eclipse of the moon of Kepler-47c are the to occur once a year.

Explanation:
https://brainly.com/question/24547936
"If one strand of a DNA molecule has the base sequence ATAGGT, then the complementary base sequence on the other strand of DNA will be TATCCA.
DNA is a double helix molecule composed of two long chains of nucleotides. The complementary nucleotides in opposite DNA strands are paired together by hydrogen bonds.
In DNA, there are four types of nucleotides, each one containing a different nitrogenous base (i.e., Adenine, Guanine; Cytosine and Thymine).
According to the base pair rules, Adenine always pairs with Thymine by two hydrogen bonds, whereas Guanine pairs with Cytosine by three hydrogen bonds.
In conclusion, if one strand of a DNA molecule has the base sequence ATAGGT, then the complementary base sequence on the other strand of DNA will be TATCCA."
