Delivering nutrients to the cells through the bloodstream is not associated with the digestive system.
How are nutrients delivered to the cells?In the process of digestion, the nutrients are absorbed into the bloodstream from the small intestine. The food particles are broken down into smaller components, and the solid waste is excreted from the body. However, the digestive system has no role in delivering nutrients to the cells.
In the body, all the cells require to have nutrients and oxygen, and they require their wastes to get discarded. All these functions are performed by the circulatory system of the body.
The blood vessels and the heart function in combination to provide the cells with the nutrients. With the assistance of the network of blood vessels, the blood collects nutrients from the food from the small intestine and delivers them to each of the cells present in the body.
Thus, the nutrients are not delivered to the cells by the digestive system, it is done by the circulatory system.

If a female fruit fly heterozygous for red eyes (X RX r) crossed with a white-eyed male (X rY), what percent of their offspring would have white eyes? (Draw a Punnett Square.)
Answer:
6.25%
Explanation:
Given that:
The trait of a female fruit fly that is heterozygous for red eyes = XRXr; &
The trait of a white-eyed male is XrY_ ;
since Y is dominant y; the male trait can either be XrYR or XrYr
So, let assume that it is XrYr
Then; if each trait self crossed; we have:
XRXr = XX Xr XR Rr
XrYr = XY Xr rY rr
Thus, the punnet Square can be computed as:
XX Xr XR Rr
XY XXXY XXYr XXYR XRYr
Xr XXXr XXrr XXRr XRrr
rY XrYX XxYr XrYR RrYr
rr XrXr Xrrr XrRr Rrrr
∴
the percentage of offspring that would have white eyes XrY_ is:
1/16 = 0.0625
= 6.25%

HELP ME I WILL GIVE BRAINIST AWANERR AND On a separate sheet of paper, choose three animals, one that lives in water, one that lives on
land, and one that flies. Explain how each one moves and how it is uniquely adapted for
movement within its environment.
Answer and Explanation:
Land - Lion
Water - Sealion
Flies - Bees
Lions have strong retractable jaws that help them eat their prey and that way they adapt to their enviroment.
The Sealion's thick, oily fur and a layer of blubber allow them to keep a high temperature in cold waters.
A Bees body carries an electrostatic charge that attracts pollen and that way they can keep it in them.

Which of the following might be an adaptation for a predator? AS SOON AS POSSIBLE NEED HELP PLS THX
Answer:
we need the answers
Explanation:
Answer:
Many predators have adaptations that help them survive in the wild. For example, the snake shown below has camoflauge coloring to look like its surroundings. This gives it the element of surprise when going to attack its prey. These adaptations help the predator in hunting for food. Predators have "weapons", or adaptations, that help them hunt and kill prey. Predators' three main "weapons" are teeth, claws, and jaws. The lion below has all 3 of these "weapons" or adaptations that are used for catching its prey. A lion has sharp claws for catching and grabbing hold prey such as a zebra, and strong jaws and teeth for biting and killing the zebra and for ripping off and chewing the meat.

How can the freezing of surface waters make the water that is left unfrozen denser
Explanation:
When an aqueous solution freezes, the unfrozen solution becomes denser. That's because some of the water has been removed as ice. However, the solutes remain dissolved in a solution with a smaller liquid volume. The concentration of the solution increases, so the density increases.
this is because water expands as it gets cold hence floating leaving the unfrozen water dense
List at least two variables that might influence the rate of cellular respiration.
Answer:
Answer below !
Explanation:
1) Oxygen Concentration
2) Temperature
3) Glucose Availability
Hope I helped and have a great day ∩^·ω·^∩ !
Cellular respiration in living tissues is reduced at low temperatures. The amount of kinetic energy needed for chemical reactions like cellular respiration to occur decreases as temperature rises.
What variable that influence the rate of cellular respiration?Since all living cells require both glucose and oxygen to operate properly, variations in the concentration of glucose have an effect on the rate of cellular respiration. If a cell's glucose level is low, it cannot produce energy in the form of ATP molecules.
High oxygen concentrations enable cells to perform aerobic respiration, which uses oxygen to build ATP and generates more ATP than anaerobic respiration, which occurs when oxygen is not present.
As a result, increased cellular respiration is often associated with warmer temperatures.
Therefore, Oxygen Concentration, Temperature, Glucose Availability

What happens to a CO2 molecule when an infrared wave hits it?
The energy from the photon causes the CO2 molecule to vibrate. Some time later, the molecule gives up this extra energy by emitting another infrared photon. Once the extra energy has been removed by the emitted photon, the carbon dioxide molecule stops vibrating.

What is Sickle cell anemia?
Sickle cell anemia is a hereditary disease which provides less oxygen to cells due to a change in the shape of red blood cells which fails to carry oxygen to cells.
In sickle cell anemia, the effected or mutated part is the beta gene that normally makes hemoglobin but due to the mutation in the amino acid, the protein formed is defected and fails to perform its normal function.
As mentioned above, it is a heredity diseases and pass from generations to generations.If Mary has a child with someone who does not have a mutated sickle cell allele, there is a 25% probability that the child will be a carrier.
Therefore, The statement is true about Mary is If Mary has a child with someone who has sickle cell disease, there is a 50% probability their child would have the disease. Thus, option A is correct.

Does DNA in animals and plants use the same nitrogenous base pairs?
Answer: There are pretty obvious differences between plants and animals, but – at the chemical level – the cells of all plants and all animals contain DNA in the same shape – the famous “double helix” that looks like a twisted ladder. What’s more, all DNA molecules – in both plants and animals – are made from the same four chemical building blocks – called nucleotides.
