Answer:
ATP , a complex organic chemical found in all forms of life, is often referred to as the molecular unit of currency because it powers metabolic processes. Most ATP is produced in mitochondria through a series of reactions
Explanation:
Mitochondria convert chemical energy from the food we eat into an energy form that the cell can use. This process is called oxidative phosphorylation.

Answer:
First Blank: Taiga
Second Blank: Tropical Rain forest
Third Blank: Desert
Explanation:
Process of elimination
1) we're given 4 answer choices but only three blanks. A tropical dry forest is not a thing so we know that one can't be it.
2) To be honest, I didn't know the first one off the bat, so I moved to the second blank and could easily tell it was the rain forest
3) The last blank was also obvious, being that desert climates are quite well known
4) So that left me with Taiga which I used for the first blank

In a species of rabbit, F is the dominant allele for brown fur, and f is the recessive allele for black fur. Two rabbits have four offspring. Three have brown fur, and one has black fur. Which of the following could describe the genotypes of the parents?
Answer:
A. Both parents are heterozygous, with one dominant allele and one recessive allele.
Explanation:
I just did it and I got it right
Both parents are heterozygous, with one dominant allele and one recessive allele. This statement describes the genotypes of the parents.
What is homozygous and heterozygous?There are two sets of chromosomes found in human beings and the pair of alleles is known as homozygous and hetrozygous. Homozygous is defined as a particular person having two common or identical genes these are known as homozygous. Hetrozygous is defined as particular person having different alleles are known as hetrozygous.
Allele is defined as differentiation of the pattern of nucleotides at the common position on a long DNA molecule. Chromosomes are the long thread type structure present in the inner side of nucleus of plants as well as nucleus.
The main composition of chromosome is protein and DNA molecule. Chromosomes trasffers from one generation to other generation or from parents to their children and they carry genetic information.
Therefore, Both parents are heterozygous, with one dominant allele and one recessive allele. This statement describes the genotypes of the parents.

The James-Lange theory of emotion is different from the Cannon-Bard and

A. does not acknowledge the importance of the body.
B. says the brain and body are both important.
ОО
C. says the thalamus routes the signals.
D. does not acknowledge the limbic system.
A. does not acknowledge the importance of the body.
What is James-Lange theory?The James-Lange theory is a psychological theory of emotion that argues that emotions arise from physiological reactions to events in the environment.
According to the theory, emotions are not inherent or innate, but rather are learned through experiences with external stimuli. The theory proposes that when a person experiences an event, their body reacts with physical arousal, and it is this physical arousal that then gives rise to the subjective experience of emotion. For example, if someone is scared, their heart rate will increase, and it is the physical arousal caused by this increase in heart rate that produces the feeling of fear. The James-Lange theory has largely been discredited, but it continues to influence contemporary theories of emotion and to inform research in the field of psychology.

In a block and tackle system each pulley that you add will all the force to be ____.
1. decreased
2. increased
Answer:decreased
Explanation:
Answer:
Decreased
Explanation:
When you add extra pulleys, the minimum force that is needed to be given off by the person pulling lowers. For example if you have one pulley and pull on it, you require more force to move the object than your friend with two pulleys. He requires half the force that you do to move the object.

If the Universe was born at the Big Bang, what existed before then
Explanation:
In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today.
Or at least, that's what we've been told by physicists for the past several decades.
But new theoretical physics research has recently revealed a possible window into the very early universe, showing that it may not be "very early" after all. Instead it may be just the latest iteration of a bang-bounce cycle that has been going on for … well, at least once, and possibly forever.
Of course, before physicists decide to toss out the Big Bang in favor of a bang-bounce cycle, these theoretical predictions will need to survive an onslaught of observation tests.
The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe.
