Answer:
The answer is B because the sun melts the core of the comet
The sun's energy causes the comet to form a bright tail. The correct answer is A.
When a comet approaches the Sun, the Sun's energy causes various effects on the comet.
As the Sun heats up the comet, it causes the icy nucleus of the comet to vaporize and release gas and dust into space.
This process is known as outgassing. The released gas and dust form a glowing envelope called a coma around the nucleus.
Additionally, solar radiation and solar wind push the released gas and dust away from the comet, forming a glowing tail that points away from the Sun.
So, the correct option is A.

Geese fly in a v-like formation when migrating. Which statement is evidence that supports advantages of this group behavior? (4 points)
A) Birds can work together to find food and shelter.
B) Birds conserve energy and reduce wind resistance.
C) Birds need to move faster to avoid being seen by predators.
D) Birds can compete for mates when they fly together.
Answer:
B
Have a nice day :D
Birds conserve energy and reduce wind resistance when they fly in V-like formation.
Why Geese fly in a V-like formation?Flying in a v-like formation allows geese to conserve energy and reduce wind resistance as they migrate. The lead goose breaks the wind for the rest of the group, which allows the other geese to fly more efficiently and use less energy. This group behavior helps the geese to cover long distances during migration, as they are able to fly for longer periods of time without tiring.
The other options do not provide evidence of advantages of this group behavior. Option A) may be true, but it is not specific to flying in a v-like formation. Option C) is not necessarily related to group behavior, as geese may need to move faster for other reasons. Option D) is not relevant to the topic of migration.

Some types of syrup are almost entirely made of glucose molecules. If a person ate some syrup like this, what would happen to her ability to exercise?
A: it would be harder for her to exercise because her digestive system would need to use more enzymes to combine the glucose molecules together.
B It would be easier for her to exercise because glucose moves through the circulatory system faster than other food molecules usually do.
C Nothing would happen to her ability to exercise, but her respiratory system would not work as hard, since glucose has more energy than oxygen molecules.
D Nothing would happen to her ability to exercise, but her digestive system would not work as hard, since glucose is already small enough to get to her cells.
Answer:
D. Nothing would happen to her ability to exercise, but her digestive system would not work as hard, since glucose is already small enough to get to her cells.
Explanation:
According to this question, some types of syrup contains an entirety of glucose molecules. Hence, eating a syrup like this will have no effect on the person's ability to exercise, however, since glucose is the simplest unit of carbohydrate food sources, it gets digested easily.
Originally, glucose molecules, which are products of digestion, enter into our cells to be used to synthesize energy. However, for a syrup already made up of glucose molecules, the digestive system would not work as hard, since glucose is already small enough to get to her cells.
Glucose is the simplest form of carbohydrate, which is digested by the human digestive system. The syrups that are completely made of glucose molecules will not affect the person's ability to exercise.
The correct option is:
Option D. Nothing would happen to her ability to exercise, but her digestive system would not work as hard, since glucose is already small enough to get to her cells.
Glucose is the primary source of energy in all living organisms.
If a person is consuming a syrup made up of glucose molecules, it will not affect the ability of a person to exercise.
The glucose is present in simpler form, which will be directly absorbed by the cells to carry out functions and yield energy.
Thus, the digestive system will work normally because the cells are supplied with glucose and it won't affect the ability of the person to exercise.
Therefore, option D is correct.

gene is a segment of DNA on a chromosome. How are genes related to the proteins made by a cell?
Answer:
The DNA in genes is transcribed into RNA and translated into proteins
Explanation:
The sequence of DNA in a gene is transcribed into a messenger RNA (mRNA). This sequence of this mRNA is translated into a sequence of amino acids that form a protein.
The sequence of DNA in a gene directly affects the amino acids, and therefore the structure and function of, a protein.
Answer:
The structure of the genes in a cell determines the structure of the proteins made by the cell.
Explanation:
How do limiting factors determine the carrying capacity of an ecosystem ?
Answer:
Limiting factors determine carrying capacity. The availability of abiotic factors (such as water, oxygen, and space) and biotic factors (such as food) dictates how many organisms can live in an ecosystem. Carrying capacity is also impacted by the availability of decomposers.
Explanation:
Carrying capacity is determined by limiting variables. Limiting factors can be divided into two categories: those that depend on the density and those that don't.
What are the limiting factors?Limiting factors can be divided into two categories: those that depend on the density and those that don't. These names are accurate in their meanings.
No matter how big or little, expanding or contracting, the population is affected by density-independent causes. For instance, regardless of the density of any one population, a wildfire that burns through a dense forest in the Everglades has a significant effect on every population in the area.
The majority of density-independent limiting variables fall into the abiotic (nonliving) group, which includes wildfire. Hurricanes, pollution, and seasonal climate extremes are other density-independent variables.
Therefore, Carrying capacity is determined by limiting variables. Limiting factors can be divided into two categories: those that depend on the density and those that don't.

In one plant species petal color follows INCOMPLETE DOMINANCE. If there
are alleles for both red and white plants, what would a heterozygous plant's
phenotype be?
Red
Pink
White
Red and White
Answer:
Pink
Explanation:
Incomplete dominance is when one allele is not entirely dominant over the other. The resulting phenotype of the heterozygote is intermediate between the two alleles. That means the flowers would be pink.
Red - no, this would be true if red was dominant to white
Pink - yes, this is an intermediate phenotype
White - no, this would be true if white was dominant over red.
Red and White - no, this would be true if the alleles were co-dominant and both equally but independently expressed.

Humans often invade spaces that were once isolated, such as beaches, affecting how animals produce offspring. Humans are overtaking the natural habitat of sea turtles, reducing the space where they deposit their eggs. Females will only deposit eggs on the land where they were hatched, and if that is taken from them they will never lay eggs. Which is NOT a step humans can take in helping sea turtles? A) Respect the areas that have been roped off for turtle eggs B) When turtle eggs are found, move them to a safe place C) When boating, try to avoid places where turtles swim and eat D) If found, do not disturb eggs or sea turtles that are laying eggs
Answer:
B) When turtle eggs are found, move them to a safe place.
Explanation:
Based on the given article, we can learn that human encroachment has decreased the private lands/ spaces for animals to reproduce properly. One such case is that of the sea turtles. As the females only "deposit eggs on the land where they were hatched", it is important to keep them safe and undisturbed.
Therefore, one step that isn't helping the turtles is to move the eggs to a safe place. This is because female sea turtles "will never lay eggs" if their eggs are ever taken away from the original place they were laid at.
Thus, the correct answer is option B.

B. A decrease in the population of sloths
C. A decrease in the number of boa constrictors
D. An increase in the population of fruit bats
E. A decrease in the population of poison dart frogs
Answer:
A, C, E
Explanation:
If the beetles disappeared from this community, changes likely to occur include
an increase in the number of strangler figs, an increase in the population of fruit bats and decrease in the population of poison dart frogsThe beetles are insects which eat up strangler figs and a decrease mean an increase in its number.
The population of fruit bats will increase as they will have more strangler figs available for food.
Poison dart frogs will decrease because they feed primarily on beetles in the ecosystem.
