Answer:
This question is incomplete as it lacks the image. The answer is:
D. A repressor that is unable to bond to the DNA
Explanation:
The expression of a gene in a prokaryote like bacteria is regulated at the transcription level. Normally, a Gene is expressed by first undergoing transcription from DNA to mRNA with the aid of an enzyme called RNA polymerase.
However, a protein called REGULATORY PROTEIN which serves as a repressor inhibits the binding of RNA polymerase to the DNA sequence. According to this question, the gene will only be expressed if the repressor is unable to bond to the DNA, hence, not being able to prevent transcription.
Compare the practices of shelterwood cutting, clearcutting, and seed-tree cutting.
ANSWER:
Clearcutting removes all the trees within a certain area at one time. Shelterwood cutting also removes all the trees in an area, but does it in stages over several years. Seed-tree cutting removes all the trees except for a select number of mature trees that can then reseed the area. Seed-tree cutting and shelterwood cutting allow for the harvested areas to recover over time without direct intervention

Autosomal Dominant Compelling Helio Ophthalmic Outburst (ACHOO) Syndrome is characterized by uncontrollable sneezing in response to the sudden exposure to bright light, typically intense sunlight. ACHOO syndrome is inherited in an autosomal dominant manner. If a heterozygous father has children with a recessive mother predict the outcome of their offspring. Using the allele (A) for dominant and (a) for recessive, identify the following using complete sentences:
Father genotype
Mother genotype
Possible offspring genotypes
Possible offspring phenotypes
Possible offspring percentage breakdown
Answer:50% chance possible offspring

all living organisms have DNA. That DNA is made of the same building blocks(nucleotides). what does this evidence suggest?
where the copying of
the DNA molecule begins.
Answer:
DNA replication initiates at specific points, called origins, where the DNA double helix is unwound. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis.

The given question provided the data of an experiment to determine the effect of water temperature on the amount of sugar that dissolves in a beaker of water and asked to identify the components:
Amount of Water (mL) - constantThe temperature of Amount of Sugar - constantThe Temperature of water (°C) - variableAmount of Sugar dissolved (g) - variableIn any research investigation or experiment, there are three main parts that are:
Independent variable: These are the variables that are manipulated or change to see the effect on the dependent variable, these are manipulated by the researcher. In this investigation, the independent variable is the temperature of the water as it affects the amount of sugar that dissolves.Dependent variables: these are the variable that also changes due to change and according to the change in the independent variables. In this investigation, the amount of sugar that dissolves changes according to the change in the temperature of the water, thus, its dependent variable.Constant or control: these are the parts that do not change during the experiment so there is no other influence occur in the Dependent variable.Thus, the correct answer is -

Which hormone causes the endometrial layer inside the uterus to thicken?
A. luteinizing hormone
B. estrogen
C. testosterone
D. progesterone
I’ll give brainiest:)
Answer:B
Explanation:Estrogen causes the lining to grow and thicken to prepare the uterus for pregnancy. In the middle of the cycle, an egg is released from one of the ovaries (ovulation). Following ovulation, levels of another hormone called progesterone begin to increase.
In sexual reproduction, two parent cells contribute genetic information to form offspring that are genetically different from both parents. Which of the following best describes an advantage of sexual reproduction?

A
The model illustrates active transport because energy is required for solute particles to

B. The model illustrates diffusion because solute particles are moving from an area of higher
concentration to an area of lower concentration
C. The model illustrates facilitated diffusion because protein channels allow solute particles
to cross the cell membrane.
D. The model illustrates osmosis because water molecules are moving from an area of higher
concentration to an area of lower concentration,
Answer:
A. The model illustrates active transport because energy is required for solute particles to cross the cell membrane.
Explanation:
Active transport is the transport of molecules from a region of lower concentration to a region of higher concentration. In other words, movement occurs against a concentration gradient.
Due to this, it requires energy in form of ATP for this movement to occur. Hence, based on this question, the model illustrates active transport because energy is required for solute particles to cross the cell membrane.

answer the question below please
pancreatic amylase is a digestive enzyme that digests starch in the small intestine. pancreatic amylase's optimum pH is slightly basic, which the presence of NaHCO3 provides. indicate which test tubes (1-3) would show digestion of starch following incubation. Explain why the others would not.
Tube 1 = water, starch
Tube 2 = water, starch, pancreatic amylase, HCI
Tube 3 = water, starch, pancreatic amylase, NaHCO3
Answer:
Tube 3
Explanation:
Pancreatic amylase's optimum pH is basic, NaHCO3 is a base so it will provide the optimum pH for the enzyme to catalyse the breakdown of starch.
In tube 1 there will not be the breakdown of starch as there simply isn't any enzyme to break it down.
In Tube 2, the enzyme pancreatic amylase will most probably become denatured (loss of shape), as HCl is acidic which causes it to lose shape causing a change in the active site and will never be able to catalyse the breakdown of starch.

How does soil composition affect the number and types of organisms an environment can support?
(Biome majors)
Answer:
The number of organisms an ecosystem can support depends on the resources available and abiotic factors, such as quantity of light and water, range of temperatures, and soil composition. Given adequate biotic and abiotic resources and no disease or predators, populations (including humans) increase at rapid rates.
