The gene for a long neck also gives stronger, faster muscles, which gives tortoises with this trait
an advantage in catching insects. How would this advantage affect the population of tortoises from
Generation 1? How may that affect subsequent generations?
Answer:
it would help them thrive
Explanation:
because it anables them to catch more with there stronger faster necks
The shift in the traits of tortoises in the population states how natural selection drove the evolution of the tortoises.
Why do tortoises shift in their traits?During the evolution, with an extended period of time, the shorter vegetation became less available and tortoises with short necks had the disadvantage to survive in that area.
Tortoise develops genes for a long neck and having stronger, faster muscles, which gives tortoises with this trait an advantage in catching insects.
This natural selection helps the tortoises, to survive by catching more food in a particular area, it states tortoises with long necks are the only tortoises living during evolution.
Therefore, this advantage increases the survival rate of the tortoise population.

Complete the flowchart to show the stages of cellular respiration and fermentation.
Cellular Respiration and Fermentation
Answer:
The stages of cellular respiration are: Glycolysis, pyruvate oxidation, Krebs cycle and phosphorylative oxidation.
The fermentation stages are: glycolysis and pyruvate regeneration.
Explanation:
Cellular respiration is a biochemical process that occurs in all aerobic organisms and aims to promote the obtaining of the necessary energy so that the cells can perform the activities they need to perform. Cellular respiration occurs in mitochondria and oxygen must be present in the process.
Fermentation is the biochemical process that replaces cellular respiration in organisms that do not survive in the presence of oxygen, the anaerobic organisms that are some fungi and bacteria. Fermentation also aims to produce cellular energy.

What letter is the second layer of the rock?
Answer:
Soil is a basic and fundamental natural resource, which took millions of years in its formation, resulting from the processes of disintegration and decomposition of rocks due to weathering. As much as many rocks, due to their hardness levels, seem indestructible, they all end up decomposing, even if slowly. Weathering is the general process that causes the deterioration of rocks. He is responsible for producing all the clays, all soils and dissolved substances that end up carried by rivers to the oceans. We can subdivide it into two types: chemical weathering and physical weathering. The first occurs when the minerals of a given rock undergo a chemical alteration or dissolution – and here the action of water is very important. The second occurs when there is a fragmentation of solid rock, through mechanical processes that do not change its chemical composition. Both reinforce each other. The smaller the pieces of rock created by physical weathering, the greater the surface for chemical weathering to act.
Rocks, reduced in particles through weathering, can accumulate as soil or, through erosion, be transported or deposited in the form of sediments somewhere else. Erosion is then defined as the process in which weathered materials (i.e., dismantled into smaller mineral fractions) are displaced or removed from their origin, usually by the action of water or air currents. A third geological process that should be mentioned is the dispersion of mass, which usually moves in isolated events, downhill, terrestrial materials modified or not by weathering, including large fragments of unchanged rocks.

Directional selection differs from stabilizing selection in that:
a.Directional selection favors one extreme phenotype, whereas stabilizing selection favors intermediate over extreme phenotypes
b.Directional selection requires new mutations whereas stabilizing selection uses existing variation
c. Directional selection operates only in small populations, whereas stabilizing selection only works in large populations
d. they both do nothing, these are terms I made up while writing this retake
Answer:
a. Directional selection favors one end of the phenotype distribution, whereas
stabilizing selection favors intermediate over extreme phenotypes
Explanation:
Directional selection is called directional because it favors one phenotype over another, and stabilizing selection finds a balance between phenotypes.
Directional selection differs from stabilized selection in that it prioritizes one end of the phenotypic distribution, but stabilized selection prioritizes the middle over extreme phenotypes.
What is phenotype selection stabilization?The stabilized choice is the opposite of a destructive choice. Prefer intermediate varieties rather than individuals with extreme phenotypes. Stabilization of choice tends to remove more serious phenotypes and results in reproductive success of standard or average phenotypes.
What is an example of a stabilization choice?Stabilization of selection If the evolutionary pressure selects for two extremes of the trait, the population experiences stabilization of selection. For example, plant height can be affected by stabilizing choices. Plants that are too small may not be able to compete with other plants for sunlight.

Describe how the conservation of matter and energy is applied to stellar formation. In your answer discuss the early components of stars and what happens at the end of stellar lifecycles. Think about the matter in a star and what happens to it.
Answer:
Explanation:
DNA polymerase has multiple mechanisms for editing and error correction whereas the capacity for error correction in RNA polymerases seems to be quite limited. However, like DNA mutation, an RNA polymerase error in transcription can cause production of a mutated protein. The limited error correction of RNA polymerase seems to be inconsistent with the potential serious consequence of producing a protein with an altered amino acid sequence. Select three reasons that explain why error correction is not as necessary in RNA polymerases as it is in DNA polymerases.
The given question is incomplete as the option are not provided however, the correct options are as follows:
Defective proteins are often degraded quickly, making their effects temporary.
Single amino acid substitutions caused by errors in mRNA transcription would not affect protein function.
Unlike DNA mutations, mRNA transcripts have short half-lives and are not inherited across many generations.
Degradation of defective proteins activates mRNA repair pathways RNA polymerases synthesize many transcripts per gene, so only a small fraction of RNA transcripts would have errors.
ch mRNA molecule is only translated once and then degraded
Answer:
The correct answer is - statements 1, 3, and 4.
Explanation:
DNA polymerase is the enzyme that is responsible for the production of the new DNA molecule and any mutation in this enzyme that will inhibit the DNA repair process which affects future generations.
RNA polymerase is an enzyme that is responsible for the transcription of DNA to mRNA and any error-prone mRNAs have chances of degradation. Error in DNA replication is from generation to generation as it is inherited
The process of transcription is quick.

4 Select the correct answer. A family has a Y-linked disease that affects the father. What is the chance of a male offspring inh А. 100% OB. 50% Oc. 25% OD. 0% Reset Next
Answer:
Remember that males have an x and y chromosome, while women have two x chromosomes.
Explanation:
This means that a female offspring (daughter) inherits her father's only x chromosome and one of her mother's x chromosomes, while a male will receive his father's y chromosome and one of his mother's x chromosomes.
This means that the boy will necessarily inherit his dad's Y chromosome, and any diseases that it carries.
The chance of a male offspring inheriting the disease is
A) 100%
Answer:
Mother
Explanation:
This mutation needs two X chromosomes. Only the mother has two X chromosomes (XX). The father is male, so he only had one X chromosome (XY).
