Answer:
The process is called oxidative phosphorylation and it happens inside mitochondria. In the matrix of mitochondria the reactions known as the citric acid or Krebs cycle produce a chemical called NADH. NADH is then used by enzymes embedded in the mitochondrial inner membrane to generate adenosine triphosphate (ATP).

What might happen if genetically modified deer mice with white fur where accidentally released into the wild population of mice? Explain what would happen to each population of mice, brown and
gray. Discuss how the addition of this genetic variation will affect the future generations of mice.
Answer:
They die.
Explanation:
If genetically modified deer mice with white fur were accidentally released into the wild population of mice, they will die and decrease in population because these genetically modified deer mice with white fur can't survive harsh conditions of the mice. Their colour also attract the predators at night so they catch these genetically modified deer mice with white fur and feed on them which automatically decrease its population.
I’m pretty sure it’s correct but if someone could double check pls
it would be testies and ovaries
why is it difficult to farm in tilted/inclined landscapes?
Answer:
Farming can lead to the loss of natural habitats.This is destroying natural habitats and changing the very nature and look of our rural landscape.
hope it helps
It is difficult to farm in an incline landscape because initial cost is high, high operational cost, Limited crops can be grown. Thus, due to these following reason, inclined farming becomes difficult.
What is vertical farming?Vertical farming is a practice of growing crops on a hilly or incline land.
However, it may have some disadvantages like high operational cost, high labor cost, only a limited number of crops can be grown.
Hence, due to these reason, tilted farming is difficult.

Three potted plants were kept in a dark cupboard for two days before being used for an experiment. Each plant was then put under a bell jar under different conditions for six hours . Bell jar D contains a potted plant with a small cup of sodium hydroxide solution with light pointed towards it Bell jar E contains a potted plant with light pointed towards it Bell jar F contains a potted plant with aluminium foil on top of the bell jar with light pointed towards it a)explain why their was no starch in the leaves at the end of the two days in the cupboard b)what is the purpose of sodium hydroxide put under bell jar in D?
Answer:
a. There were starch in the leaves at the end of two days in the cupboard because there was no sunlight to provide the energy for photosynthesis in the dark cupboard. Also, any previously synthesized starch in the plant leaves were used by the plant for its own metabolic requirements during the period the plant was in the cupboard. Therefore, staying in the cupboard for two days destarched the leaves.
b. The purpose of sodium hydroxide put under bell jar in D is to remove any carbon dioxide that may be present under the bell jar. This is to demonstrate that even in the presence of sunlight, carbon dioxide is required for photosynthesis to occur in plants.
Explanation:
Photosythesis is the process by which green plants manufacture their food (carbohydrates which are stored as starch) in the presence of sunlight. The site of photosynthesis in plants is the leaves.
The experimental design is to study the conditions necessary for photosynthesis to occur. For photosynthesis to occur, there must be presence of sunlight, carbon dioxide and water. Carbon dioxide and water serve as the raw materials for photosynthesis while the energy required is provided by sunlight.
The answers to the observations from the experiment are given below :
a. There were starch in the leaves at the end of two days in the cupboard because there was no sunlight to provide the energy for photosynthesis in the dark cupboard.

The H substance is needed for the proper phenotypic expression of the A, B, and AB blood types in the ABO blood typing system in humans. Individuals who are recessive for the H substance (hh) will have a type O phenotype, even if they have the A and/or B alleles. Two individuals, each with type AB blood and heterozygous at the H locus have children. What is the probability they will have a child who is phenotypically type O?
Answer:
The correct answer is - 4/16.
Explanation:
In this question, it is stated that in ABO blood system the proper phenotypic expression of A, B, AB blood types needs H substance. If an individual has recessive for the H substance (hh) will have a type O phenotype.
The cross: ABHh and ABHh
gametes: two set of AH, BH, Ah, Bh
Punnett:
AH BH Ah Bh
AH AAHH ABHH AAHh ABHh
BH ABHH BBHH ABHh BBHh
Ah AAHh ABHh AAhh ABhh
Bh ABHh BBHh ABhh BBhh
As shown there is only 4 out of 16 offspring are recessive for H substance therefore, only 4/16 will have O blood group
What is cell wall???
Answer:
You can simply define the cell wall as a semi-rigid thick protective structure that surrounds the cell membrane of some types of cells for protection and defining the shape of the cell. The cell membrane alone cannot provide the required rigidity or strength. All living organisms are composed of cells.
why do cells divide even after an organism reaches adulthood?
Answer:
The answer is most definitely the second option or "B". This is because, how you think you grow fingernails, or skin over a wound.
The answer is 2nd option ,full grown organisms need to replace aging and damaged cells

Parasitic flatworms have a well-developed head with eyespots and nerves concentrated into a brain. e. Most planaria are found in marine environments, but some dwell in freshwater and moist terrestrial environments.
Complete question:
Which of the following statements is NOT correct about the flatworms?
A. There are three complete tissue layers.
B. Flatworms may be either free-living or parasitic.
C. Flatworms have a sac body plan, with only a mouth and no anus.
D. Parasitic flatworms have a well-developed head with eyespots and nerves concentrated into a brain.
E. Most planaria are found in marine environments, but some dwell in freshwater and moist terrestrial environments.
Answer:
D. Parasitic flatworms have a well-developed head with eyespots and nerves concentrated into a brain.
Explanation:
Flatworms are inferior organisms, meaning that they do not have nerves concentrated in a brain. Their nervous system is, in general, composed of nerve cords forming a net. The arrangement depends on each of the groups. They have one or more pairs of primitive eyes, which function is to find the light. These eyes cup-shaped and are composed of pigmentary cells.
Flatworms have bilateral symmetry. Their body is plane dorsoventrally and can be divided into two specular halves by the sagittal plane. This plane crosses through the body from the anterior extreme to the posterior extreme. The frontal plane divides the body into two different halves, the ventral one with the mouth and the dorsal one.
These organisms only have one opening in their bodies directed to the digestive system, which is the mouth.
Flatworms are aquatic and, most of them are marine animals, although there can be a few groups that inhabit freshwater. Some species might even be terrestrial. Most of them are free-living organisms, but there are also some parasitic forms.
