Answer and Explanation:
A. Hello. You did not enter answer options. However, we can state that mutation, natural selection and genetic drift will be the microevolution mechanisms that will affect the gene pool of these humans. This is because the new environment and the small number of living beings, will make this population completely susceptible to all these evolutionary factors, which will affect, in different ways, the gene frequencies in a population.
B. As the amount of living beings and human beings has become very small, the world will have a low genetic diversity. This will make it difficult for these humans to adapt to the new environment and will make them more susceptible to possible diseases that will arise in this new environment. This will make these humans more fragile and make it harder for them to multiply.
C. The evolution mechanism is the Gene Flow. Gene Flow refers to the exchange of genetic information between individuals in a population, through the donation of gametes that occur in reproductive processes. In this case, we can consider that the individual with green eyes, upon arriving in the community with individuals without green eyes, began to reproduce descendants, who, upon receiving the gametes responsible for green eyes, began to populate this community with this characteristic.

Jenna's pencil fell off of her desk and she quickly reached down to catch it before it hit the ground. In the process, the (1)_____ system first recognized the falling pencil. It sent signals to the (2)______ system, which then moved the components of the(3) _____ system in order to catch the pencil.
Options:
(1) 1. Nervous 2. Muscular 3. Skeletal
(2) 1. Nervous 2. Muscular 3. Skeletal
(3) 1. Skeletal 2. Digestive 3. Nervous
The answer is:Jenna's pencil fell off of her desk and she quickly reached down to catch it before it hit the ground. In the process, the (1) Nervous system first recognized the falling pencil. It sent signals to the (2) Muscular system, which then moved the components of the(3) Skeletal system in order to catch the pencil.
Explanation:
The nervous system receives the signal that the pencil is falling. In other words, Jenna sees or feels that the pencil falls, so the senses send a signal to the nervous system to produce a response. We call this a stimuli. Once that the nervous system receives and processes the stimuli, it elaborates an answer. The answer is to send a signal to a group of muscles that will move certain bones to make the movement that will catch the pencil. The muscles are from the muscular system, and they are attached to the bones, which are part of the skeletal system. When the muscles contract, they move the bones and make the movement possible.
The presence of a negative allosteric effector on an allosteric protein would: a. cause a shift to the left in the sigmoidal curve. b. increase the number of R conformations. c. decrease the cooperativity of the substrate. d. raise the apparent value of the equilibrium constant, L. e. increase the likelihood of the binding of S.
Answer:
d. raise the apparent value of the equilibrium constant, L.
Explanation:
Allosteric regulation is a type of regulation of an enzyme by binding an effector molecule at a site other than the protein's active site (i.e., the allosteric site). The equilibrium constant (L) refers to the transition between two forms of an allosteric protein in absence of a ligand. The properties of allosteric enzymes are explained by conformational changes associated with a low-affinity tense (T) state, or a high-affinity relaxed (R) state. Negative allosteric effectors are molecules that bind to the allosteric site on an enzyme in order to decrease its activity, thereby leading the enzyme to a low activity T state and thus increasing the value of the equilibrium constant.

Answer:
a. amount of a pesticide that can be applied to a food and how much of the pesticide that is permitted to remain on the food in the marketplace.
Explanation:
Pesticides are chemical substances used to get rid of or kill pests that attack crops on farmlands. These pesticides, although help the farmer to get rid of his pest problem and likely have an increase in yield, are dangerous to human and animal health if consumed.
As set up by the Environmental Protection Agency (EPA), pesticide tolerance is the amount or quantity of pesticide chemical that can be applied to a food and how much of the pesticide that is permitted to remain on the food in the marketplace.
During diffusion, molecules move from areas of blank concentration to areas of blank concentration. Diffusion does not require blank to move molecules.
Answer:
high; low; energy.
Explanation:
Diffusion can be defined as the movement of gas molecules from a region of high concentration to a region of lower concentration until an equilibrium is attained or reached. This mixing of gas molecules in the liquid or gaseous state is due to their kinetic energy of random motion i.e without requiring bulk motion.
This ultimately implies that, diffusion is a phenomenon through which gas molecules in either a gaseous or liquid state spread out in response to a concentration gradient, which is simply the difference in concentration of the gases across a space.
During diffusion, molecules move from areas of high concentration to areas of low concentration. Also, diffusion does not require energy to move molecules.
In conclusion, increasing the surface area of a gas increases its collision rate and it's considered to be an evolutionary strategy that maximizes the diffusion of gas molecules because it catalyzes the rate of a gaseous reaction.
The organisms native to an area will impact the types of soil found in that area.

What type of unconformity did Hutton see at Siccar Point and how was this uniformity formed?
Answer:
Hutton's Unconformity
At Siccar Point, during the lower Silurian Llandovery epoch around 435 million years ago, thin beds of fine-grained mudstone were laid down gradually deep in the Iapetus Ocean, alternating with thicker layers of hard greywacke formed when torrents swept unsorted sandstone down the continental slope. Siccar Point is a rocky promontory in the county of Berwickshire on the east coast of Scotland. It is famous in the history of geology for Hutton's Unconformity found in 1788, which James Hutton regarded as conclusive proof of his uniformitarian theory of geological development.

What connections are there between the changing surface of the Earth and the evolution of life?
Please help!!
Evolution is the modification of heritable traits. The change in the earth's surface is directly linked to evolution as the formation of the species, abiotic factors, and gases happened due to changes.
What is evolution?
Evolution is the adaptation and survival of the modified organism due to changes in favorable environmental conditions. It is an important factor governed by natural selection.
The evolution and the change in the earth's surface are interconnected as the changes in the earth's crust made the presence of the living beings possible. The conditions at early times were unfavorable that underwent many changes till the present scenario.
The atmosphere and crust were unfavorable for the living beings that got changed and improved with oxygen quality, water, and the crust for the organism to exist, survive and reproduce to continue their lineage.
Therefore, evolution is linked to changing the earth's surface.

The teacher was unaware of the difference between suspension feeding and predation. The teacher thought that providing live copepods (2 mm long) and feeder fish (2 cm long) would satisfy the dietary needs of all of the organisms. Consequently, which two organisms would have been among the first to starve to death (assuming they lack photosynthetic endosymbionts)
Answer:
The correct answer is - Biwalves and sponges.
Explanation:
Suspension feeders are the organisms that depend on, for the dietary needs or nutriton, materials suspended in the water. The materials that are suspended are living organisms such as phytoplankton and zooplankton.
Biwalves and sponges are suspended or filter feeders and not predators like other organisms so providing copepods will not complete their food requirement and they will starve to death.
The correct answer is - Biwalves and sponges.

The concept illustrated in the flowchart is Natural selection. The correct option is 4.
What is natural selection?Natural selection is the process by which species evolve over time as the prevalence of certain traits increases or decreases in a population.
Natural selection, the mechanism by which species evolve over time, is depicted in the flowchart.
Overproduction of offspring causes competition for limited resources, resulting in a struggle for survival.
Based on their inherited characteristics, some people are better equipped to survive and reproduce than others.
These people are said to be "fit," and they are more likely to pass on their positive traits to their children. These advantageous traits become more common in the population over time, causing changes in the species as a whole.
Thus, the correct option is 4.
