Answer:
Independent variable: Planting depths of seeds
Dependent variable: plant height
Explanation:
Independent variable in an experiment is the variable that the experimenter changes or manipulates in order to bring about a measurable response. In this experiment involving the planting of radish seeds at varying depths, the DEPTH AT WHICH THE SEEDS ARE PLANTED is the independent variable.
Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the HEIGHT of the radish plants measured is the dependent variable.

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.

Using information from the diagram, state one reason why the movement in the third image represents active transport
Answer:
A protein or ion has passed through the "pump" or carrier proteins and move within the cell.
Nvm short and sweet ;)
Further info..
To move substances against a concentration or an electrochemical gradient, the cell must use energy. This energy is harvested from ATP that is generated through cellular metabolism. Active transport mechanisms, collectively called pumps or carrier proteins, work against electrochemical gradients. With the exception of ions, small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive changes. Much of a cell’s supply of metabolic energy may be spent maintaining these processes. Because active transport mechanisms depend on cellular metabolism for energy, they are sensitive to many metabolic poisons that interfere with the supply of ATP.

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.

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:
What describes G and why they face the watery inside and outside of the cell
Answer:
Because they are hydrophilic
Explanation:
The cell membrane is made up of a phospholipid bilayer. The phospholipid bilayer is made up of an arrangement of phosphate heads, which are (attracted to water) hydrophilic, and fatty acid tails, which are hydrophobic. (repelled by water).
Because they are attracted to water, the phosphate heads face the outside of the cell, where the water is
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.

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.
