I would say your answer is C.
Mutations contribute to genetic variation within species. Some mutations affect the gene that instructs the building of a protein. So mutations can cause altered protiens AND genetic disorders.

Explanation:
Which of the following is a specific variant of a character? A.) A Class B.) A Trait C.) A Species
Answer:
B.) A Trait - pls mark brainiest
Explanation:
A phenotypic trait, simply trait, or character state is a distinct variant of a phenotypic characteristic of an organism; it may be either inherited or determined environmentally, but typically occurs as a combination of the two.
You go on a trip to the Galapagos island to study the animals there for a paper you are writing on evolution, just like Darwin did. You spend 3 days taking notes on all the physical characteristics you can observe about the tortoises and then you spend 3 days observing the finches. What have you recorded? A. Inherited characteristics B. Environmental variation factors C. Phenotypes D. Genotypes
Answer:
C. Phenotypes
Explanation:
Taking notes on all the physical characteristics observed about the tortoises and then observing the finches, I have observed the phenotypes.
Phenotypes are the observable characteristics of a species which are the result of genetic expression influenced by the environmental factors.
So, phenotypes will be recorded during the trip while taking notes on all the physical characteristics which can be directly related to genotype and environmental factors.
Hence, the correct option is "C. phenotypes".

Formulating hypotheses – Propose a hypothesis to account for the data related to the cell life spans of the lining of the esophagus, small intestine, and large intestine. Please use the format,if then because
Answer:
Hypothesis: If mucus production in the submucosal layer of the esophagus is insufficient, cell longevity is affected, because it interferes with the quality of connective tissue.
Explanation:
In a scientific research the hypothesis is an assumption, a possibility that will justify the purpose of the scientific research and will help in the establishment of all the steps of this research, so that it is possible to determine if the hypothesis is true or false. In other words, we can say that the hypothesis must be formulated as an assumption, before the research that will prove it or not.
An example of a hypothesis about research on the longevity of cells that line the esophagus is: "If mucus production in the submucosal layer of the esophagus is insufficient, cell longevity is affected, because it interferes with the quality of connective tissue."

How is a clade differentiated from another clade
Answer:
A clade is a grouping that includes a common ancestor and all the descendant species of that ancestor. Clades are differentiated visually based on where they branch off from one another.
Explanation:
A clade is a grouping that includes a common ancestor and all the descendants (living and extinct) of that ancestor. Using a phylogeny, it is easy to tell if a group of lineages forms a clade. Imagine clipping a single branch off the phylogeny — all of the organisms on that pruned branch make up a clade.
Clades are nested within one another — they form a nested hierarchy. A clade may include many thousands of species or just a few. Some examples of clades at different levels are marked on these phylogenies. Notice how clades are nested within larger clades
Answer:
A clade is a monophyletic grouping in which all the organisms stem from the same branching point.
Explanation:
The organisms in a clade must all stem from the same branching point in evolutionary history, as represented in the phylogenetic tree.
how does photosynthesis relate to the formation of dna?
Answer:
During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Explanation:
In

nutrients and gases.
PLASMA
Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in.
hope this helps
Answer:
Plasma
Explanation:
Plasma is usually given to trauma, burn and shock patients. It helps boost the patient's blood volume, which can prevent shock, and helps with blood clotting. It is also the single largest component of human blood, comprising about 55 percent, and contains water, salts, enzymes, antibodies and other proteins.

Which part of the membrane can catalyze chemical reactions?
A Nucleic acids
B. Fatty acids
XC. Phospholipids
D. Enzymes
It isn’t C
Answer:
Enzymes
Explanation:
Catalysts" are agents that 'increase the rate of' , or 'speed up' , a 'chemical reaction' , when added to the reactants; and by definition, catalysts do so within affecting the reaction itself.
Enzymes can catalyze chemical reactions. Therefore, option (D) is correct.
What are the functions of enzymes?Catalysts are proteins that assist with accelerating digestion, or the compound responses in our bodies. Some substances are created and others are broken down.
Enzymes aid in the transmission of signals. Protein kinase, which is the enzyme that catalyzes the phosphorylation of proteins, is the most frequently used enzyme in the process. They break down big molecules into smaller ones that the body can easily take in.
Compounds catalyze a wide range of synthetic responses that are engaged with development, blood coagulation, recuperating, infections, breathing, processing, multiplication, and numerous other natural exercises.

The description below is about a community in a poor country in need of certain basic
necessities.
A village has no running water and no electricity. They have farms that are watered by
frequent rainstorms. With no electricity, they cannot use modern technology to improve
their lives.
One group thinks the village should install windmills to provide electricity. What is the
biggest problem with this plan?
O A. Windmills do not work in areas with rainfall.
XO B. The village should work on raising their fertility rate first.
O C. Electricity would lead to a higher carrying capacity.
D. The village may not have money for windmills.
The biggest problem with the plan of installing windmills to provide electricity in the village is the village may not have money for windmills. Therefore option D is correct.
Installing windmills requires financial resources, including the initial cost of purchasing and installing the windmills, as well as ongoing maintenance and operational expenses.
In the given description, the village is described as being in a poor country and lacking basic necessities. It is unlikely that they would have the necessary funds to invest in windmills, considering their current situation.
Therefore, the lack of financial resources becomes a significant obstacle in implementing this plan.

A) Substances are moving rapidly across the cell membrane.
B) ATP is being rapidly consumed near the cellular membrane.
C) Substances are moving from high to low concentrations.
D) Substances are moving through channels in the cell membrane.
Answer:
B) ATP is being rapidly consumed near the cellular membrane.
Explanation:
Active transport is a form of transport used by living systems in which substances/molecules move across a membrane from a region where they are less concentrated to a region where they are highly concentrated. This movement occurs against the concentration gradient, hence it requires energy in form of ATP in order to occur. The transport is said to be "ACTIVE" if it is energy consuming.
Hence, based on the explanation above, the best evidence to showcase the occurrence of active transport in a cell is the rapid consumption of ATP near the cellular membrane. ATP will be used to pump needed substances into the cell via the cell membrane, serving as the semi-permeable membrane.
