Genetic mutations introduce new gene forms in a population. For instance, the mutation that affects
hemoglobin alters the shape of the red blood cell and makes it sickle-shaped. Which statement
below would explain why the sickle-cell mutation has spread through the gene pool?
A. There is a selective advantage to having Sickle Cell Anemia.
B. This kind of mutation demonstrates a common ancestor.
C. The sickle cell mutation has no benefit.
D. Sickle cell anemia increases the risk of death.
Answer:
B- this kind of mutation demonstrates a common ancestor.
Explanation:
in order to have sickle cell anemia you need to have both recessive alleles from both parents, this recessive allele has to be continuous passed down from generation to generation on both sides, which shows a common ancestor from long ago

what kind of dams that beavers make
Answer:Beavers build their dams out of trees and branches that they cut using their strong incisor (front) teeth! They also use grass, rocks, and mud.
Explanation:beaver impoundments
Beaver dams or beaver impoundments are dams built by beavers to provide ponds as protection against predators such as coyotes, wolves, and bears, and to provide easy access to food during winter.

Which of the following occurs at #4?
1-pollenation
2-vegetative propagation
3-fertilization
4-grafting
By Pleistocene hangovers, Buchanan means: Biological traits that we have today that are the result of selective pressures that existed thousands of years ago but no longer today. Biological traits that we have today but would not have had in the environment that existed thousands of years ago. Biological traits that are better in terms of quality of life to have today, even though the selective pressures that allowed for those traits do not exist today. Selective pressures toward perfection that feel like a hangover because perfection is impossible. Selective pressures that exist today that tend to push human beings away from the pursuit of perfection.

Look at the graph...What is the optimal temperature for this enzyme?
A. 60 degrees C
B. 45 degrees C
C. 15 degrees C
D. 35 degrees C
Answer:
B: 45 degrees C
Explanation:
However, above 40-45 degrees Celsius, enzymes are usually denatured and can no longer catalyse the reaction, because the hydrogen bonds are broken, so the enzyme permanently loses its shape. The temperature at which the reaction rate is fastest is the optimum temperature.
As per the graph, the optimum temperature for the enzyme is 45 degree Celsius. The correct option is C.
What is optimum temperature?The temperature at which the enzyme exhibits the greatest activity is referred to as the optimum temperature.
Enzyme activity decreases as the temperature rises or falls. It can even become inactive at times. It is equivalent to the body temperature of a warm-blooded animal.
The kinetic energy in the substrate and enzyme molecules is optimal for the maximum number of collisions at the optimal temperature.
At high temperatures, the enzyme's shape changes, and it no longer complements its specific substrate.
It is the temperature at which the enzyme's reaction rate is fastest. It will be the point on the graph where the line reaches a peak at 45 degrees Celsius.
Thus, the correct option is C.

Describe the two ways that the atmosphere influences the temperature of the earth
Answer:
The composition of a planet's atmosphere also influences its temperature, particularly the concentration of greenhouse gases present. The Earth converts solar radiation in the visible spectrum to infrared radiation, which it emits; greenhouse gases absorb infrared radiation and warm the atmosphere.

Answer: 5. Amoebocytes have a variety of functions: delivering nutrients from choanocytes to other cells within the sponge, giving rise to eggs for sexual reproduction (which remain in the mesohyl), delivering phagocytized sperm from choanocytes to eggs, and differentiating into more-specific cell types. 6. Sponges form symbiotic relationships with a variety of microorganisms, including bacteria and algae. A symbiotic relationship between organisms is a close ecological association between two species that may be mutually beneficial or may benefit one partner at the expense of the other. However, humans are still damaging sponge populations with weighted nets and even taut fishing lines, which can slice sponges apart by accident. As a rule, anything that can affect the ocean floor will have a negative impact on sponges, as they have never developed protection against impacts. brainliest??

A gene that has many possible genotypes such as brown, red, blonde, green, blue, or hazel is known as a
A polygenic trait
B single gene trait
C polygraphic trait
D single ladies trait by Beyonce
Answer:
I think the answer would be C.
Explanation:
D is wrong for obvious reasons, elimanate any silly or impossible answers.
Since poly means muliple, and single means, not muliple (in most cases), B is elimanated.
Since Grapihic usaully refers to things that can been seen, where genic ussaully refers to more so like personality characteristics.
