Answer:

Cl- ions will move inside the cell.

Explanation:

When the equilibrium potential and is equal to membrane potential, the net charge across the membrane is equal to zero and therefore there is not movement of ions across the membrane. However, in this case, the membrane potential is -70 mV, while the equilibrium of negatively charged Cl- ions is -81 mV. In consequence, Cl- ions will tend to move inside of the cell.

The statement that represents a valid hypothesis about organic farming is as follows: Carrots that are grown with organic fertilizer will contain more vitamin A than those grown with nonorganic fertilizer (option B).

Organic farming is approach to farming based on biological methods that avoid the use of synthetic crop or livestock production inputs.

Organic farming puts value on ecological harmony, resource efficiency, and non-intensive animal and crop husbandry practices.

According to this question, many grocery stores claim that organic produce has more health benefits than traditionally grown produce. This suggests that they believe that agricultural produce grown using organic fertilizer will be more nutritious than those grown using non-organic fertilizers.

This means that the valid hypothesis regarding this claim is option B because it can be tested via experimentation.

The most appropriate technique that the physician should use to estimate the basal metabolic rate of Louisa's body is indirect calorimetry.

Indirect calorimetry is a medical technique for determining a person's resting energy expenditure. This technique is used to calculate the calories your body expends in a resting situation.

Information obtained from indirect calorimetry can be used as a guide to basal metabolism to determine whether it is normal, increased, or decreased.

Based on the above, this is the best technique the doctor has to find out why Louisa is gaining weight without changing her diet.

The genotype of the F1 offspring is YyTt, and the phenotype is yellow and tall. The probability of each phenotype in the F1 offspring is as follows yellow and tall is 1/2 or 50%, green and short is 1/2 or 50%.

Genotype refers to the genetic makeup or combination of alleles present in an organism, while phenotype refers to the observable traits or characteristics expressed by an organism. Genotype represents the genes an organism carries, while phenotype represents the physical or observable features resulting from the interaction between genotype and the environment.

When a heterozygous ail yellow plant (genotype Yy) is crossed with a homozygous short green plant (genotype tt), the F1 offspring will have the genotype YyTt and the phenotype of yellow and tall. The probability of this phenotype occurring in the F1 generation is 50%. Additionally, there is a 50% probability of the F1 offspring having the phenotype of green and short.

The statement that would correctly explains the weight you would experience on each planet is You would weigh less on planet A because it has less mass than planet B. Option D

Weight is the force experienced by an object or person due to gravity. Since it is as a result of gravitational force, it depnds on both the mass of the objct or person and the level of gravity of the planet.

Gravity is dependent on th mass of the planet, and if planet A has lesser the mass of planet B, its gravitational force will be most likly be weaker.

This therefore means a person is going to weigh less on planet A than on planet B, even though both planets have the same size.

In biology, autotrophs are organisms that can produce their own food using inorganic substances, such as sunlight and carbon dioxide.

Autotrophs  are also known as primary producers because they form the base of the food chain by converting energy from the environment into organic compounds.

The topic of autotrophs is typically covered in the study of plant biology in the context of a class 7 curriculum.

The most prevalent kind of autotrophs are plants. They do this through a process known as photosynthesis, which turns carbon dioxide, water, and sunlight into glucose (a sugar) and oxygen.

Chloroplasts, specialized organelles found in plant cells, are where this process occurs.

I suspect you are referring to a specific experiment, which measures the rate of photosynthesis at differing intensities of light. This experiment could certainly be done with land plants, but using a water plant makes it easier to have a simple way to measure the rate of photosynthesis--the counting of bubbles which come off a specific area of the plant. A water plant such as elodea (the type you commonly see in aquariums) does the process of photosynthesis just as plants that grow in the air do, but you can actually see the bubbles that indicate photosynthesis is occurring--they form on the leaves before they float to the surface, enabling an easy measurement of bubbles per minute.

Plants have chloroplasts, which in addition to giving plants their green color, perform photosynthesis, the process on which life on earth is dependent. They use the energy of the sun to use carbon dioxide and water to produce sugars and oxygen. When you are counting the bubbles on the underwater leaf, you are counting bubbles of oxygen formed during photosynthesis.

Since the field mouse is the predator of the grasshoppers,  removing the field mouse will result in an increase in the population of the grasshoppers​

Removing the field mouse could potentially affect the grasshopper population in different ways, depending on the interactions between these two species and the overall ecosystem.

If the field mouse is a predator of grasshoppers, then removing it could cause an increase in the grasshopper population, as there would be fewer predators to keep their numbers in check. This could lead to overgrazing of vegetation and other ecological imbalances.

6. Yes

7. No

8. 8 and 9

Explanation:

5. Males are depicted by square symbols. The most squares are found in generation III (4 males) so this is the answer.

6. Carriers are heterozygotes, which means they have one copy of the sickle cell allele. Let's imagine the normal allele is A and the sickle cell allele is a. A cross between two carriers is Aa x Aa. Here are the possible genotypes:

                  A          a

A               AA        Aa

a               Aa         aa

Individuals with an aa genotype have sickle cell disease. So 1:4 children of two carriers will have the disease.

7. Normal h0m0zygous individuals have the genotype AA. It is not possible for them to have an affected child, because the child will always inherit one of the A alleles from that individual (it does not matter whether they inherit A or a from the other parent, their genotype can only be Aa or AA, which are both unaffected.

8. We are looking for two affected individuals in the same family. We will be able to see they are affected because their symbols will be shaded. Individuals 8 and 9 are both heterozygous (carriers) and have 4 children. 2 affected and 2 unaffected.

The heavier ball caused more flour to spread out because it possessed greater kinetic energy due to its greater mass.

Kinetic energy is proportional to an object's mass and velocity, and since both balls were dropped from the same height, they had the same initial potential energy.

However, the heavier ball had more kinetic energy as it hit the flour, causing it to displace more flour than the lighter ball. This can be observed in everyday situations, such as a heavier object causing more damage than a lighter object when dropped from the same height.

Therefore, the relationship between mass and kinetic energy can explain why the heavier ball caused more flour to spread out.

The concentration of mercury will increases as it moves up the food chain because of biomagnification. For example, a school of small fish consumes a minute amount of mercury each, but then a larger fish eats five of the smaller fish. After this the larger fish has more mercury in its system than one small fish because it ate five small fish (along with the mercury in each of the small fish). Now a seal eats multiple large fish. Overall, the seal has the highest mercury concentration out of all the animals mentioned.

Biomagnification is "the concentration of toxins in an organism as a result of its ingesting other plants or animals in which the toxins are more widely disbursed."
