Answer:Fossils are formed in different ways, but most are formed when a plant or animal dies in a watery environment and is buried in mud and silt. Soft tissues quickly decompose leaving the hard bones or shells behind. Over time sediment builds over the top and hardens into rock

how does the operator region of dna work to regulate gene expression?.
Answer:The promoter is found in the DNA of the operon, upstream of (before) the genes. ... Some regulatory proteins are repressors that bind to pieces of DNA called operators. When bound to its operator, a repressor reduces transcription (e.g., by blocking RNA polymerase from moving forward on the DNA).

Explain how the oxidation of pyruvate links glycolysis with the citric acid cycle.
Pyruvate oxidation is the step that connects glycolysis to the citric acid cycle through the generation of acetyl-CoA.
The first thing that happens after glycolysis is that pyruvic acid passes from the cytoplasm to the mitochondrial matrix, crossing the membranes.
Pyruvic acid undergoes oxidation, a CO2 molecule is released and an acyl group (CH3-CO) is formed.
In this reaction, one molecule of NADH is formed, as in glycolysis the final product was two molecules of pyruvic acid, now two of NADH will be formed for each molecule of glucose.
Each acyl group binds to a Coenzyme A and acetyl Coenzyme A is formed, at this time the citric acid cycle begins.
Acetyl-CoA is degraded in the citric acid cycle to produce energy when cellular needs demand it.
Therefore, we can conclude that glycolysis achieves from the degradation of glucose to obtain 2 molecules of pyruvate, which is a previous step to give acetyl-Coa, which is the starting molecule of the citric acid cycle.

Overproduction
Variation
Descent with Modification
Adaptation
Answer:
The answer is Descent with Modification
Descent with Modification refers to the passing on of traits from parent organisms to their offspring. This passing on of traits is known as heredity, and the basic unit of the heredity is the gene.
What is significant drawback to transferring electricity produced by solar where sunshine is abundant to states where it is not
Answer:
The transfer could only occur during the day because it cannot store solar energy.
Explanation:
The transfer of electricity produced from solar energy only occurs during the day because it cannot store solar energy at a tremendous level. At homes, we can easily store the electricity made from solar energy with the help of batteries but for providing electricity to a state where thousands of houses are present, enormous batteries are needed to store it which can't be made because of very high cost so that's why the solar energy can not be stored.

In what direction do substances diffuse across the cell
membrane?
Answer:
Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes "down the concentration gradient." The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane.

HERC2 gene is made of
Answer:
Dna i think im not sure if it is right?
Explanation:
Answer:
HERC2 is a giant E3 ubiquitin protein ligase, implicated in DNA repair regulation, pigmentation and neurological disorders. It is encoded by a gene of the same name belonging to the HERC family, which typically encodes large protein products with C-terminal HECT domains and one or more RCC1-like (RLD) domains.
Explanation:
Read this Pulmonology Consult excerpt:On physical exam, the patient is alert. He takes occasional pauses when he says long sentences, but otherwise, he is not in any distress. He has an occasional cough during his exam. His skin is pink and dry, and his lips are moist. His heartbeat is regular in rate and rhythm, without a murmur. On lung examination, he has whispered pectoriloquy on the right side with decreased breath sounds. He does not have any retractions or nasal flaring noted. His liver and spleen are not large.According to the excerpt, what was found upon lung examination on the right side?A. "Whispered pectoriloquy" - a chest that protrudes like the keel of a ship when the patient whispersB. "Whispered pectoriloquy" - "speaking from the chest"; used as a means of finding masses in the lung. The whispered word is audible in areas where fluid or a mass is presentC. "Retractions" - reverberations in the chest when it is struckD. "Retractions" - a dull sound in the chest when it is struckE. "Whispered pectoriloquy" - a chest that is hollowed out when the patient whispers
Answer:
B. "Whispered pectoriloquy" - "speaking from the chest"; used as a means of finding masses in the lung. The whispered word is audible in areas where fluid or a mass is present
Explanation:
Auscultation in medicine, is the action of listening to sounds from the heart, lungs, or other organs, usually using a stethoscope, in order to perform medical diagnosis.
Auscultation is performed for the purposes of examining the circulatory and respiratory systems, as well as the alimentary canal. The procedure is best performed in a quiet examination room. A stethoscope is used to magnify internal sounds. Small changes in breath sounds are carefully observed in order to make a diagnosis.
Whispered pectoriloquy is used to detect vocal resonance. It is used as a means of finding masses (consolidations e.g. pus) in the lung and is performed by having the patient quietly whisper a word. If fluid or a mass is present, words that are whispered may be heard clearly.

Explain mendel's experiment with peas on inheritence of characters considering only one visible contrasting character.
Ples answer in making points, it is for 5 marks.
➜ Mendel conducted breeding experiments with garden peas:
[i] He studied plants (pure) of a tall/short varities.
[ii] He crossed them and obtained F1 progeny.
[iii] He found that F1 progeny was all tall plants.
[iv] He selfed the (hybrid) plants if F1 progeny.
[v] He found that in F2 progeny there were tall as well as short plants.
[vi] The three quarter plants were tall and one quarter was short.
(or any other contrasting character may be taken).
Note: Here, F1 means First fillial generation and F2 means Second fillial generation.
Mendel selected garden pea for his breeding experiment because of its contrasting characters such as height of the plant, yellow or green seed, round or wrinkled seed shape. ... Then he allowed the hybrid plants of F1 generation to self-pollinated. In F2 generation all the progeny were tall as well as short plants...We used to take this character, we may choose different.
