Look again at the enzyme diagram and it’s target molecule. How might a mutation affect the interaction between the enzyme and its target and the function of the enzyme in the organism?
By viewing the enzyme diagram and its target molecule, we can infer that a mutation might affect the interaction between the enzyme and target because it may change the shape of the enzyme and consequently inhibit its function.
What is a genetic mutation?A genetic mutation can be defined as a permanent alteration in the DNA sequence that makes up a gene, which affects the production of a protein and may have a wide range of effects on the function of a cell.
Therefore, with this data, we can see that a genetic mutation may modify the protein and thus affect the reaction.

i need help finding the chi square value and please explain how u did it, can someone also explain this p value null hypothesis?
Answer:
p^2 + 2pq + q^2 = 1
0.16 + 0.48 + 0.36 = 1 (from the question)
hence, q^2 = 0.36
then, q= square root of 0.36
= 0.6

describe how the chemical reactions of cellular respiration and photosynthesis keep the amount of carbon dioxide and oxygen balanced
Answer:
Cellular respiration and photosynthesis have the opposite formulas of each other. Cellular respiration is C6H12O6 + 6O2 --> 6CO2 + 6H2O and photosynthesis is 6CO2 + 6H2O --> C6H12O6 + 6O. Because both require the products of the other equation, they are balanced.

Composes the outside of the cell membrane
Carries hereditary information
Pair each structure with its function:
*Nucleic acid
*Protein
*Lipid
*Carbohydrate
*Water
Answer:
Despite differences in structure and function, all living cells in multicellular organisms have a surrounding cell membrane. Just as the outer layer of your skin separates your body from its environment, the cell membrane (also known as the plasma membrane) separates the inner contents of a cell from its exterior environment. This cell membrane provides a protective barrier around the cell and regulates which materials can pass in or out.
Structure and Composition of the Cell Membrane
The cell membrane is an extremely pliable structure composed primarily of two layers of phospholipids (a “bilayer”). Cholesterol and various proteins are also embedded within the membrane giving the membrane a variety of functions described below.
A single phospholipid molecule has a phosphate group on one end, called the “head,” and two side-by-side chains of fatty acids that make up the lipid “tails” (Figure 3.1.1). The lipid tails of one layer face the lipid tails of the other layer, meeting at the interface of the two layers. The phospholipid heads face outward, one layer exposed to the interior of the cell and one layer exposed to the exterior (Figure 3.1.1).
This diagram shows the structure of a phospholipid. The hydrophilic head group is shown as a pink sphere and the two tails are shown as yellow rectangles. This diagram shows a phospholipid bilayer. Two sets of phospholipids are arranged such that the hydrophobic tails are facing each other and the hydrophilic heads are facing the extracellular environment.
Figure 3.1.1 – Phospholipid Structure and Bilayer: A phospholipid molecule consists of a polar phosphate “head,” which is hydrophilic and a non-polar lipid “tail,” which is hydrophobic. Unsaturated fatty acids result in kinks in the hydrophobic tails. The phospholipid bilayer consists of two adjacent sheets of phospholipids, arranged tail to tail. The hydrophobic tails associate with one another, forming the interior of the membrane. The polar heads contact the fluid inside and outside of the cell.
The phosphate group is negatively charged, making the head polar and hydrophilic—or “water loving.” A hydrophilic molecule (or region of a molecule) is one that is attracted to water. The phosphate heads are thus attracted to the water molecules of both the extracellular and intracellular environments. The lipid tails, on the other hand, are uncharged, or nonpolar, and are hydrophobic—or “water fearing.” A hydrophobic molecule (or region of a molecule) repels and is repelled by water. Phospholipids are thus amphipathic molecules. An amphipathic molecule is one that contains both a hydrophilic and a hydrophobic region. In fact, soap works to remove oil and grease stains because it has amphipathic properties. The hydrophilic portion can dissolve in the wash water while the hydrophobic portion can trap grease in stains that then can be washed away. A similar process occurs in your digestive system when bile salts (made from cholesterol, phospholipids and salt) help to break up ingested lipids.

Charles Darwin took a five-year voyage around the world observing different
organisms and their adaptations. Darwin concluded that change was happening ever
so slightly in organisms, until eventually leading to a new species. What form of evolution was Darwin describing?
Answer:
Natural selection.
Explanation:
Natural selection is when organisms who are most adapted to their environment survive and pass on their genes while those with "unfit" genes die and don't get the chance to reproduce! This slowly creates a population that is most well suited to their habitat. Hope this helps again LOL! :)

an ecosystem is a community of living organisms and their environment within...
Answer:
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms.

WHICH SPECIES OF ANIMALS ARE AFECTED THE MOST BY ACTIONS OF HUMANS IN CURRENT TIMES?SUGGEST WAYS TO PROTECT THEM.
Answer:
Polar Bears
Explanation:
The species that has most likely been the most affected by human actions would be the Polar Bears. The human population is growing at a staggering rate and this causes industrialization to expand rapidly as well. This continued and increasing use of fossil fuels for all of our basic necessities is rapidly heating up our world (Global Warming) and melting the ice caps. Without this it becomes nearly impossible for Polar bears to survive as they cannot find shelter and ultimately end up starving to death due to not being able to hunt for food as well. The only way to protect them is to begin protecting our planet, switching to more environmentally friendly sources of energy, and being mindful of our choices.
