Answer:
A. III only
Explanation:
Cytochromes are found only in the mitochondrial membrane as part of the electron transport chain. They are vital to the downward cascade of energy as electrons are passed from the NAD+ and FAD produced during glycolysis and the Krebs cycle into the electron transport chain to eventually produce ATP.

How is a recessive allele different from a dominant allele?
Answer:
A dominant allele is an allele that will express the dominant phenotype when only one allele is present. In contrast, a recessive allele is an allele that is only expressed when both alleles are in the genotype.
How to calculate the time of death?
Answer:
One method of estimating the time of death is to measure body temperature. The normal equation for this is: 37.5oC - 1.5 oC This formula equates to the body temperature (37.5oC), which loses 1.5 oC per hour until the temperature of the body is that of the environment around it; known as the ambient temperature.
Do the people at T mobile keep your browser history and things like that??
Answer:
2x - 9y = 23
5x - 3y = -12x - 9y = 23
5x - 3y = -12x - 9y = 23
5x - 3y = -12x - 9y = 23
5x - 3y = -12x - 9y = 23
5x - 3y = -12x - 9y = 23
5x - 3y = -1

Describe the structure of human kidney.
answer in brief..okay..i appreciate correct one.
➜ Kidneys are bean-shaped and located at the back of abdomen, one on either side of backbone. Its inner concave surface has a depression called hilum through which renal artery enters and renal vein leaves the kidney. Kidney has two regions: outer cortex and inner medulla. Each kidney has a large number of filtering units called nephrons.
Note: See picture attached to get the idea.
❅ Structure of Kidney —
Length: 10-12 cm.
Width: 5-7 cm.
Thickness: 2-3 cm.
Location: both sides of the vertebral column.
EXPLANATION:❅ Hilum —
The hilum is a notch which is present on the inner surface towards the centre of the kidney. This notch allows the entrance of blood vessels, nerves and ureter in the kidney.
❅ Renal Pelvis —
Funnel-shaped structure towards the inner hilum. It has two zones. The inner zone is known as the medulla, and the outer zone is known as the cortex.
❅ Medulla —
It is divided into small medullary pyramids which are conical in shape. These are projected through the calyces.
❅ Cortex —
It is a structure which is present between the renal columns and the medullary pyramids. Columns of Bertini is another name of the renal columns.
❅ Nephrons —
These are particularly important and functional units of a kidney. They are complex tubular structures present in the count of millions. There are two parts of a nephron which include glomerulus and tubule. The glomerulus is responsible for the filtration of blood and toxic substances like nitrogenous wastes and ammonia.
How do tidal power plants generate electricity?
A. A barrage stores water during high and low tide. When the water is released, it turns the plant's turbines.
B. A barrage holds back water during high tide. The force of the water against the barrage turns the plant's turbines.
C. A barrage allows water to flow during high and low tide, this turn's the plant's turbines.
D. A barrage stops water from flowing out at low tide, creating a force that turns the plant's turbines.
Answer:
B
Explanation:

Describe the similarities and differences between prokaryotic cells and eukaryotic cells.
Answer:
Prokaryotic cell have no membrane bound organelles and no membrane bound nucleus. Eukaryotic cells are found in plants, animals, protists and fungi.
In the image below, the beetles that are being squished just happened to be in the wrong place at the wrong time. The
man did not jump around trying to step on specific bugs, but just happened to step on bugs that were in his path. This
occurrence is completely random. There was no plan for taking these bugs out of the population. Observe the initial
population and compare to the final population. How will the population be effected by these particular beetles
being stepped on?
PLS HELP, I WILL MARK BRAINLIEST I NEED HELP
Answer: 0%
Explanation: white eyes is rr and red eyes is RR and if it had Rr it would still be red.
So the boxes filled in are rr and RR and offspring are Rr Rr Rr Rr which means there is no chance of a female offspring with white eyes (I think)

Explanation:
What is an example of mutation that could cause a phenotype that makes organism better suited for its environment?
Explanation:
for example:-If a mutation led to brighter feather colouring in birds, the brighter feathers may allow those individuals with the mutation to reproduce more frequently, because they are seen as being more attractive and a desirable mate.
Changes to body cells affect
A. Gene activity
B. Individuals.
C. Cell division.
D. Offspring
I will give Brainliest for correct answer.
Answer:
Cell Division. Read explanation
Explanation:
It wouldn't be any of the sex cells so that would take out gene activity and offpsring. The only thing that changes the somatic (body) cells would be the slowing of cell division which I would assume is the correct answer.

Why do sunflowers grow better if there are lots of ladybirds in the garden?
Answer:
It is because the ladybugs kill and eat the pests that eat the sunflowers, which alows the sunflower to grow without interruption.

What is selective breeding?
Long before scientists had technology to manipulate genes, people used selective breeding to manipulate mating. Selective breeding, also called artificial selection, is the process by which humans artificially select plants or animals that are going to breed and flourish according to what we want from them. The process of selective breeding starts with selecting the animals or plants that have the best characteristics. Then force them to breed with one another. Later, select the best of the offspring and combine them with the best you already have and breed again. The process then continues over several generations to develop the desired traits.
What are the benefits to selective breeding?
Selective breeding is an extremely helpful technique that has been used for hundreds of years. In terms of farming, we use this process to develop the best features: maximum yield (or the most possible product), good health and disease resistance. This is done with cows to make more and better tasting milk. We have increased the number of eggs and the size of eggs each hen can produce. In terms of plants, we have selectively bred wheat to be resistant to disease.
This has also helped people who race horses. They are able to combine the fastest, strongest, or highest jumping horse to have the best chance of winning. Humans have also worked to make cats that are hypoallergenic (meaning they don’t cause allergic reactions. They wed out cats that cause allergies and breed cats that produce the smallest reactions.
Breeders use this to make sure that pedigree dogs remain pure bred. This is done purely for physical appearance to ensure wins at dog shows. They have a similar process to create exotic animals like ligers. They cross 2 different species: a tiger and a lion to create this hybrid, or combination of two organisms.
What are disadvantages to selective breeding?
All of the advantages for selective breeding are for humans. Because of this, there are many disadvantages for the animals. In all cases, the gene pool, the number of possible alleles, is reduced. This is because the species are getting the same “best” genes all the time. This is bad because if a new disease appears, all of the species can be wiped out. In general, there is a large amount of variation in a species that gives some resistance to a disease. However, with selective breeding, they are very closely related to one another. So, if one is affected, they probably all will be. Hybrids that humans make are generally sterile, meaning they cannot produce offspring. Purebred dogs can also have very bad health problems because of their small gene pool.
What is a strict aerobe
An organism able to live and reproduce only in the presence of free oxygen (e.g., certain bacteria and certain yeasts). Organisms that grow in the absence of free oxygen are termed anaerobes; those that grow only in the absence of oxygen are obligate, or strict, anaerobes.
