Chimpanzees would be more closely related to humans than to bonobos is the best predicts how phylogenetic relationships might be revised if transposon 1 was not found in chimpanzees.
A phylogenetic relationship is the study of the relationship among the organisms of a species or a population through evolution.
These relationships are able to learn or identifying by using the similarities found in DNA(Deoxyribonuclic acid) , RNA, or protein sequences
phylogenetic relationship helps to find the relation between ancestor and descendent sequence.
It also helps to identify the time of divergence between organisms that use to share a common ancestor.
Some assumptions which is made in identifying the phylogenetic relationships are given below----
All life arises from a common ancestor.
The relationship is determined by the traits shared between the different organisms which is either may be genetically or anatomically.

B. reduce FADH2 to FAD D. pump hydrogen ions across the membrane
Answer:
7. D. breaking the glucose molecule to produce acetyl CoA
8. C. Oxaloacetate
10. phosphorylate ADP to ATP
Explanation:
Cellular respiration is the metabolic process by which energy in form of ATP is obtained in a cell. However, it occurs in three major stages namely: glycolysis, Krebs cycle and electron transport chain (oxidative phosphorylation).
- Glycolysis is the process where glucose is broken down to produce pyruvate, which is then processed into acetyl coA before it enters the next stage (Krebs cycle).
- Krebs cycle is the stage where series of REDOX reactions occur to produce OXALOACETIC ACID as a final product, which accepts acetyl coA for another cycle to begin.
- Electron transport chain (ETC) uses the energy derived from the electron carriers energy NADH and FADH2 to phosphorylate ADP to ATP in a process called CHEMIOSMOSIS.

What produces all of the light in the universe?
Answer:
Source of Light in UniverseAlthough the Sun doesn't light up the other stars, it does provide the daylight here on Earth; and the moon and planets we see are illuminated by that same sunlight. All stars produce light (and other kinds of energy) through nuclear reactions, using the energy stored in the tiny nucleus at the center of atoms.Explanation:
THANKS❤❤why do all the planets in the solar system orbit the sun in the same direction ?
Answer:
The result of the initial rotation of the cloud of gas and dust that condensed to form the Sun and planets. As gravity condensed the clouds, of angular momentum increased the rotational speed and flattened the cloud out into a disk.
How many molecules are represented?
2Fe(NO3)2
Taking into account the definition of Avogadro's number, 2 moles of Fe(NO₃)₂ contains 1.2046×10²⁴ molecules.
Avogadro's NumberAvogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance.
Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.
Amount of moles in this caseIn this case, you have 2 moles of Fe(NO₃)₂.
Then you can apply the following rule of three: If 1 mole of the compound contains 6.023×10²³ molecules, 2 moles of the compound contains how many molecules?
amount of molecules= (6.023×10²³ atoms× 2 moles)÷ 1 mole
amount of molecules= 1.2046×10²⁴
Finally, 2 moles of Fe(NO₃)₂ contains 1.2046×10²⁴ molecules.

PHET Energy Skate Park Simulation .Consider this equation: gravitational potential energy = mgh. Which of those variables is changing as the skater moves up and down the track?
Answer:
h - height
Explanation:
gravitational potential energy = m * g * h
m stands for mass. Mass doesn't change in physics
g stands for gravitational acceleration. It is a constant.
h stands for height. When the skater moves up and down the track the height from the ground changes. Therefore this variable does change.
In the equation gravitational potential energy = mgh, the variable that is changing as the skater moves up and down the track is the variable h, which represents the height or vertical position of the skater.
As the skater moves up the track, the height increases, resulting in a higher value for h. Conversely, as the skater moves down the track, the height decreases, leading to a lower value for h.
The other variables in the equation, m (mass) and g (acceleration due to gravity), typically remain constant unless specified otherwise. Therefore, the changing variable in this equation as the skater moves up and down the track is the height (h).
