Answer:
v = 5 m/s
Explanation:
Given that,
The distance covered by a runner, d = 400 m
Time, t = 80 sec
We need to find the runner's average speed. It is equal to total distance covered divided by time taken. It can be given by:
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{400\ m}{80\ s}\\\\v=5\ m/s[/tex]
So, the runner’s average speed is 5 m/s.

You would need to breathe in a lot more air because your body would have fewer molecules from food.
Your cells would not work as well because even though they would have enough oxygen molecules from the air, they would not have enough glucose molecules from food.
Answer:
last one
Explanation:
because you having digestive have nothing to do with your oxygen and breathing
Problems with the digestive system make it very difficult for the body to digest enough food, and it is harder to exercise with digestion problems like this because cells would not work as well because they would not have enough glucose molecules, which is the last option.
What is the function of the digestive system during exercise?
Exercise is important for the body, and the digestive system plays an important role in it because the digestive system breaks down the food, and then the simplified food enters the blood and is then taken up by the cells for the different activities. If there are any issues with the digestive system, the food will not be well absorbed into the cells, and no energy will be produced for the exercise.
Hence, the answer is that cells would not work as well because, even though they would have enough oxygen molecules from the air, they would not have enough glucose molecules from food. The last one is the true fact.

If a plant cell needs energy for endocytosis, what does it use and where does the energy come from?
Explanation:
Active transport uses energy stored in ATP to fuel the transport. ... Endocytosis methods require the direct use of ATP to fuel the transport of large particles such as macromolecules.
Hope this helps!
If a plant cell needs energy for endocytosis, its use and energy come from- Active transport from ATP.
Endocytosis is an energy-using process by which cells internalize molecules by engulfing them.
Endocytosis needs to use directly ATP to fuel the transport of large particles such as macromolecules, parts of cells that can be engulfed by other cells in a process called phagocytosis.Active transport is the movement of molecules across a cell membrane in the direction against their concentration gradient, i.e., moving from a low concentration to a high concentration and this uses cellular energy.Thus, If a plant cell needs energy for endocytosis, its use and energy come from- Active transport from ATP.

What caused the chromosomal alteration in the number 21 chromosomes? (LS3.2) A. Part of one chromosome attached to another chromosome B. Some of the genes on a chromosome were reversed C. A duplicated chromosome failed to separate during meiosis D. A part of a chromosome was lost
Answer:
The correct answr is - A. Part of one chromosome attached to another chromosome.
Explanation:
Translocation is one of the chromosome abnormality that cause change in the number of the chromosome. In the translocation a part of the chromosome breaks off and bind or attached to the another chromosome.
The translocation cause various disorderes in individual one of them is Down syndrome which is the result of the alteration of chromosome number 21. In this translocation or specicifically the chromosome portion of chroromosme 14 breaks off and reattaches to the chromosome 21 result in one normal 14 and two normal 21 chromosme so there is trisomy occurs.
Answer:
A duplicated chromosome failed to separate (nondisjunction)
Explanation:
If nondisjunction occurs during meiosis I, homologous chromosomes fail to separate. This produces abnormal gametes that contain two members of the affected chromosome or none. This is why there is an extra chromosome in the 21 chromosomes.

Protein is found throughout the body—in muscle, bone, skin, hair, and virtually every other body part or tissue.
What is protein?It makes up the enzymes that power many chemical reactions and the hemoglobin that carries oxygen in your blood. At least 10,000 different proteins make you what you are and keep you that way.
Protein is made from twenty-plus basic building blocks called amino acids.
Because we don’t store amino acids, our bodies make them in two different ways: either from scratch, or by modifying others. Nine amino acids—histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine—known as the essential amino acids, must come from food.

What are the genotypic and phenotypic distributions for the F1 and F2 generations from a cross between a chick with black (BB) feathers and chicken with white (WW) feathers if the color is determined by alleles that show codominance. The heterozygote is an erminette chicken, which is black and white speckled.
Answer:
Please find the punnet square to this question as an attachment
F1 generation:
genotype = BW
Phenotype = Erminette offsprings
F2 generation:
genotype = BB (1): BW(2): WW(1)
Phenotype = 1 Black, 2 Erminette, 1White
Explanation:
This question involves a gene coding for feather color in chickens. The allele for black feathers (B) is codominant with the allele for white feathers (W) to form an erminette chicken (black and white speckles).
According to this question, a cross between a chick with black (BB) feathers and chicken with white (WW) feathers will result in an all erminette chicken (BW) in the F1 generation (see attached image)
Also, in the F2 generation got by self-crossing the Erminette genotype in the F1 generation (BW), the following genotypic and phenotypic ratios are observed:
Genotypic ratio = BB (1): BW(2): WW(1)
Phenotypic ratio = 1 Black, 2 Erminette, 1White

Explanation:
Los ARN mensajeros, también conocidos como ARNm, son uno de los tipos de ARN que se encuentran en la célula. Éste en particular, como la mayoría de los ARN, se sintetiza en el núcleo y luego se exporta al citoplasma, donde la maquinaria de traducción, la maquinaria que realmente fabrica las proteínas, se une a las moléculas de ARNm y lee en ellas el código para producir una proteína específica. Así que en general, un gen, el ADN de un gen, puede ser transcrito en una molécula de ARNm que puede acabar dando lugar a una proteína específica.

Patients wear protective gear when being X-rayed. What substance is being protected directly from mutation?
Answer:
Radiation has a potential of causing germ cell mutations that may be passed on to future generations.
Explanation:
i think so, hopefully this helps;(
Ionizing radiation damage cells and cause double-strand breaks that let more DNA in. These additional fragments of DNA find their way to the nucleus and cause cellular mutations. Protective gears are worn to prevent this.
What are X-rays ?X-rays are a form of electromagnetic wave radiation. Using X-ray imaging, your body's interior can be visualized. The photos depict the various bodily parts in various shades of black and white. This is due to the fact that various tissues absorb radiation in different ways.
Ionizing radiation, a type of radiation that x-rays create, has the ability to destroy living tissue. This is a risk that gets worse the more exposures someone has over the course of their lifetime. However, exposure to radiation normally carries a low risk of acquiring cancer.
Therefore, protective gears are worn during x-rays to avoid mutations.

Chromosome pair 23 are the sex chromosomes and are responsible for determining the gender of a human. The large chromosome is an X chromosome, and the small chromosome is the Y chromosome. If there are two X’s, then the individual is a female. If there is an X and Y, then the individual is a male.
Answer:
This is true.
Explanation:
More commonly, an X chromosome will die and get replaced by a Y chromosome (all humans start off as females). When this occurs, the substitute Y chromosome causes changes in the zygote to occur; they begin developing male genitalia (i.e. penises, testicles, prostates, etc.).
