Answer:
Protons : Protons (H+ ions).
ATP synthase uses the protons flowing into the matrix to bind ADP and Pi and release ATP.
Explanation:
The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP.
Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyse conversion of ADP to ATP.

1. Imagine that the class had 25% of students with free earlobes and 75% with attached earlobes. What would this suggest about the frequency of the dominant (F) and recessive (f) alleles for these traits in the class population? Explain your reasoning.
Answers
Answer:
People with free earlobes carry one or two dominant alleles which means that the free earlobe is a dominant trait over attached earlobes that carries two recessive alleles. The recessive allele is represented by f and the dominant allele is represented by F.
It is given that in a class 25% of students in the class had free earlobes which means either 25% of total alleles are FF or Ff and the rest 75% have ff. It suggests that recessive alleles have more frequency than dominant alleles.

the prefix gen- means "begin." how does this apply to the key term generation?
Answers
The prefix "gen-" in "generation" implies the act of beginning or bringing forth something new, marking a departure from what existed before.
The prefix "gen-" does not specifically mean "begin," but rather derives from the Greek word "genēsis," which translates to "origin" or "creation." In the context of the key term "generation," the prefix "gen-" conveys the notion of creating or producing something new.
When we refer to "generation," we often think of a group of individuals born and raised during a particular period. However, the concept of generation extends beyond human demographics. It encompasses the idea of a collective creation or production of something that arises or evolves within a specific time frame.
In the broader sense, generation implies the development, formation, or emergence of something novel, whether it be ideas, technologies, energy sources, or social movements. It captures the essence of progress and the continuous cycle of renewal and innovation.

How does fossils record help scientists observe changes in organism over time ?
Answers
As the world changes, plants and animals change with it. Aside from a few living fossils, the species we see today are very different from species that lived in the past.
What is the minimum age of a fossil?A living being that lived more than 11 thousand years ago is considered a fossil, that is, before the Holocene, which is the current geological epoch.
Ancient remains or evidence, but less than 11,000 years old, such as sambaquis, are classified as subfossils.
The dating of a fossil can be done based on the already known percentage of Carbon-14 (C14) in relation to Carbon-12 (C12) of living matter (without decomposition).
Thus, the fossil record can be used to show that organisms changed to meet new conditions.

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.

Snakes Used to Have Legs and Arms Until These Mutations Happened
The ancestors of today's slithery snakes once sported full-fledged arms and legs, but genetic
mutations caused the reptiles to lose all four of their limbs about 150 million years ago, according
to two new studies.
Both studies showed that mutations in a stretch of snake DNA called ZRS (the Zone of
Polarizing Activity Regulatory Sequence) were responsible for the limb-altering change. But the
two research teams used different techniques to arrive at their findings.
According to one study, published online today (Oct. 20, 2016) in the journal Cell, the snake's
ZRS anomalies [differences] became apparent to researchers after they took several mouse
embryos, removed the mice's ZRS DNA, and replaced it with the ZRS section from snakes.
The swap had severe consequences for the mice. Instead of developing regular limbs, the mice
barely grew any limbs at all, indicating that ZRS is crucial for the development of limbs, the
researchers said.
Looking deeper at the snakes' DNA, the researchers found that a deletion of 17 base pairs
within the snakes' DNA appeared to be the reason for the loss of limbs.
1. Without having DNA samples from snakes 150 million years ago, state how scientists could
know that snakes once actually had legs.
Answers
In the present day, snakes don't have legs. Snakes ancestors, on the other hand, used to have legs. 150 million years ago, genetic mutations caused reptiles to lose all four limbs. This change was caused by anomalies in a stretch of snake DNA known as the Zone of Polarizing Activity Regulatory Sequence (ZRS).
Two different studies have revealed that mutations in the snake's ZRS caused the limb-altering change. Scientists determined that the deletion of 17 base pairs in the snakes' DNA was the cause of the limb loss after thoroughly analyzing the snakes' DNA.
Although scientists don't have DNA samples of snakes from 150 million years ago, they can still infer that snakes used to have legs from the existing fossil records. Fossilized snakes with legs have been discovered by paleontologists. As a result, we know that snakes once had legs and that they were lost due to a genetic mutation.
Anatomical similarities between current snakes and other reptiles with legs also indicate that they are related. This means that the snake's ancestors had limbs but lost them due to a genetic mutation. Because the deletion of 17 base pairs in the snakes' DNA was responsible for the loss of limbs, scientists know that the mutation occurred after the appearance of the first snakes.

Why do mapping experiments become less accurate when the distances between genes become large? View Available Hint(s) Why do mapping experiments become less accurate when the distances between genes become large? Interference is greater when the distance between genes is large. Multiple crossovers are more common. Crossover gametes become less common. Recombination occurs less frequently in long chromosomes.
Answers
Answer:
Multiple crossovers are more common.
Explanation:
Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.
A mapping experiment refers to an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
In mapping experiments, if the genetic distance increases, there would be a consequential increase in multiple crossovers causing a recombinant with an odd number of crossovers and a parental combination with an even number of crossover events by switching it back.
Hence, mapping experiments become less accurate when the distances between genes become large because multiple crossovers are more common.
Which of these pairs of arrows shows the direction of the stress that causes the normal fault?
O Arrow A and Arrow E
O Arrow F and Arrow C
O Arrow B and Arrow D
O Arrow C and Arrow D
Answers
The pairs of arrows show the direction of the stress that causes the normal fault is Arrow A and Arrow E
A fault is a fracture that results from the crust's brittle deformation. It is a displacement of the earth's crust where a significant movement has taken place. A rock must exhibit brittle behaviour in response to applied stress for a defect to form. Stress is the amount of force applied to a certain area of rock. A reversal fault is what the diagram represents. A reversal fault occurs when the hanging wall has migrated upward and the footwall has moved downward.
The direction of stress in the rock body must be compressional for a reversal fault to develop. A compressional stress is one in which the stresses are directed in the same direction. The tension forces a displacement after acting to hold the rock together. The tensional stress produced by arrows B and D results in the elongation of the crust. They appear to be separating the rocks. They have typical flaws that come with them. Thus, Arrow A and Arrow E are correct.

What is an atom?An atom is described as a particle that consists of a nucleus of protons and neutrons surrounded by a cloud of electrons.
Protons and neutrons make up the core nucleus of an atom, which is encircled by an electron cloud. In relation to the size of the atom as a whole, the nucleus is exceedingly small.
As a result, the electrons surrounding the nucleus are the primary target of interactions when particles or even light pass through an atom. The majority of the atom's remaining space, which includes the nucleus, is vacant.

which two statements correctly relate RNA amino acids , and proteins
Answers
The two correct statements that relate RNA, amino acids, and proteins are C and D.
RNA, Amino acids, and ProteinsRNA is used to build the amino acid sequence: RNA molecules, specifically messenger RNA (mRNA), serve as templates for protein synthesis. During a process called translation, the sequence of nucleotides in mRNA is read by ribosomes, and the corresponding amino acids are assembled in a specific order to form a protein.
Long amino acid sequences fold in a specific way to form proteins: Proteins are composed of long chains of amino acids. After the amino acids are synthesized and linked together, the resulting chain folds into a three-dimensional structure, which is critical for the protein's function. This folding process is driven by various interactions between the amino acid residues in the chain, allowing the protein to adopt its specific shape and perform its specific function.
