What is respiration ?Respiration is a metabolic process in which an organism's living cells use oxygen to obtain energy (in the form of ATP) and release carbon dioxide as a byproduct of the oxidation of complex organic substances.
Anaerobic respiration occurs when there is no oxygen present, whereas aerobic respiration occurs when there is oxygen. Alcohol is produced by anaerobic respiration, whereas carbon dioxide and water are the byproducts of aerobic respiration. Compared to anaerobic respiration, aerobic respiration produces more energy.
Thus, respiration is a vital process of the body.

How does genetic variation allow humans to survive long-term?
Which type of reproduction is responsible for genetic variation?
Answer:
Because natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation. Some new alleles increase an organism's ability to survive and reproduce, which then ensures the survival of the allele in the population. Sexual reproduction promotes genetic variation by producing different gene combinations. Meiosis is the process by which sex cells or gametes are created. Genetic variation occurs as alleles in gametes are separated and randomly united upon fertilization.

Which type of feather gives the bird its color?
down
barb
contour
flight
it contour
I hope it work
Contour type of feather gives the bird its color. Therefore, the correct option is C.
The outer feathers that give a bird its color and general appearance are known as contour feathers. The barbs on the branches that make up the central shaft of these feathers join to form a strong, streamlined structure. The barbs have their own little branches, known as barbules, which contain pigments that help give the bird its color.
The diverse colors and patterns seen on many bird species are determined by the arrangement and color of pigments in the barbules of contour feathers. Therefore, contour feathers are important in determining a bird's color.
Therefore, the correct option is C.

In the laboratory, yeast cells are usually grown at a temperature of 25oC. A scientist wanted to determine if yeast cells would reproduce faster or slower when the temperature was dropped to 15oC. The same number of yeast cells were placed in the same medium with the same amount of nutrients. One sample was kept at 25oC and the other one was kept at 15oC. The number of yeast cells was counted every hour for an eighteen hour period.
Answer:
This question is incomplete, however, it is asking to identify the following variables:
Independent variable: Temperature
Dependent variable: Number of yeast cells
Constants: same amount of nutrients, same number of yeast cells, same medium
Explanation:
- Independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable effect. In this experiment, the TEMPERATURE at which the yeast are kept is the independent variable.
- Dependent variable is the variable that responds to the changes made to the independent variable. It is the variable that is measured by the experimenter in the experiment. In this case, The NUMBER OF YEAST CELLS was counted, hence, it is the dependent variable.
- Constants are variables that are kept unchanged or same for all groups by the experimenter in order not to influence the experiment's outcome. In this case, the CONSTANTS are: same amount of nutrients, same number of yeast cells, same medium etc.

Cindy/was diagnosed with anemia recently, because her physician found that her blood contains a lower count of red blood cells than normal. 4 A) What is anemia's immediate impact on gas exchange?
Answer:
The correct answer would be - a decrease in the numbers of RBCs will lead to a decrease in the ability for gas exchange in a person.
Explanation:
In the case of anemia, there would be a decrease in the number of RBCs that might be due to increased destruction of these cells, or low production of RBCs, that transporting oxygen and carbon dioxide affects the ability for gas exchange in an individual.
RBCs carry and transport oxygen to various body parts and then carry back carbon dioxide from different parts of the body to the lungs for gaseous exchange but with less number of RBCs leads to impair or decreased gas exchange in the case of anemia.

Explanation:
A dog breeding is the practice of mating dogs. In the context, it is given that a dog breeder wants to purchase a male dog of three year old for her business and she founds an advertisement on the net about a purebred males that costs $700. Now before buying this purebred male dog, the dog breeder should first of all check whether the seller who is selling online is a licence breeder or not.
The dog breeder should also check whether the dog is a purebred or not and should also find out the actual age of the dog. The health of the dog should be checked by an professional vet before buying the dog.
The selling of dogs, either a hybrid or a purebred costs differently. An individual should check the license and health of the dogs before purchasing.
In the given example, the dog breeder is trying to purchase a three-year male dog. She saw an advertisement that the male dog is available at the rate of dollars 700.
Before purchasing the dog, the breeder should check:
the authenticity of the advertisementrespective seller details and valid contact information the genotype of the dog as claimed purebred, and the health of the dog from a professional veterinarian.

which molecules are not able to permeate the cell membrane
Answer:
Small uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot. Charged molecules, such as ions, are unable to diffuse through a phospholipid bilayer regardless of size; even H+ ions cannot cross a lipid bilayer by free diffusion.
Explanation:
Why can smaller cells diffuse oxygen and nutrients at a faster rate?
small surface area to volume ratio
large surface area to volume ratio
large surface area
more volume than surface area
Answer:
A further increase in the size of a cell could result in a surface area too small for adequate exchange of materials.: A large surface to volume ratio means that a small amount of living matter has a large surface through which nutrients, oxygen and wastes can diffuse.

As a frog develops from a tadpole into an adult frog, it goes through changes that are signaled by hormones within the body. Which best describes the role hormones play in changing a tadpole to a frog?
Answer: In amphibians, metamorphosis is generally associated with the changes that prepare an aquatic organism for a primarily terrestrial existence In (frogs and toads), the metamorphic changes are more dramatic, and almost every organ is subject to modification Regressive changes include the loss of the tadpole's teeth and internal gills, as well as the destruction of the tail. At the same time, constructive processes such as limb development are also evident. The means of locomotion changes as the paddle tail recedes while the hind limbs and forelimbs develop. The tadpole's cartilaginous skull is replaced by the predominantly bony skull of the frog. The teeth used for tearing pond plants disappear as the mouth and jaw take a new shape, and the tongue muscle develops. Meanwhile, the large intestine characteristic of herbivores shortens to suit the more carnivorous diet of the adult frog. The gills regress, and the gill arches degenerate. The lungs enlarge, and muscles and cartilage develop for pumping air in and out of the lungs. The sensory apparatus changes, too, as the lateral line system of the tadpole degenerates, and the eye and ear undergo further differentiation The middle ear develops, as does the tympanic membrane characteristic of frog and toad outer ears. In the eye, both ingratiating membranes and eyelids emerge.

In "gastrulation" cells begin to differentiate. They form different types of tissues so they can accomplish different purposes in the body.
True or False?
Answer:
The statement that says that In "gastrulation" cells begin to differentiate and they form different types of tissues so that they can accomplish different purposes in the body, is true.
Explanation:
Gastrulation involves a process of cell division, migration and differentiation, being one of the stages of embryonic development.
Cell differentiation and migration in gastrulation leads to the formation of germ layers, which are responsible for forming different tissues and fulfilling different functions in the body:
The outermost lamina is called the ectoderm, which can give rise to nerve tissue and part of the skin tissue. The mesoderm is the middle lamina, and from it vascular, bone, muscle, and joint tissue can develop, as well as tissues of excretory and reproductive organs. Endoderm corresponds to the internal lamina, forming in great part the mucous membrane of the organs of the digestive system.It is true, then, that In gastrulation cells begin to differentiate and form different types of tissues so they can accomplish different purposes in the body.
