What process occurs in Box A?

a. A scheme of cellular respiration. At box A, which is located in the cytosol, glucose turns into pyruvate with release of ATP and electrons carried by NADH.

b. Pyruvate from this stage is used in a cycle in box B, which is located in the mitochondrion.

c. As a result, ATP, CO2, and electrons carried by NADH and FADH2 are released.

d. The electrons carried by NADH and FADH2 from boxes A and B are used in box C (inside the mitochondrion) for transformation of a substance marked D (that comes from the cytosol) into a substance marked E (released to the cytosol) with release of ATP.

Explanation:

Answer:

Family members have a similar genetic make-up that may make them predisposed to cancer.

Explanation:

Variation in certain genes can increase the risk of developing certain cancers. This is why certain cancers run in families. There are lots of examples where the risk factor is small, but in some cases, the risk factor is very large.

For example, mutations in BRCA1 are very highly linked to the risk of breast cancer. As a result, many women with mutations in this gene opt to get a mastectomy to reduce their chances of developing breast cancer.

Answer:

Substitution Mutations

Explanation: A substitution mutation occurs when specific bases (A, T, C or G) in a gene are swapped for different ones. This type of mutation doesn't cause a difference in the number of bases like insertion or deletion mutations do. Substitution mutations just switch out one or more bases for different ones.

Hope this helps :3

A substitution mutation occurs when a base in the DNA sequence is replaced by a different base.

Substitution is a type of mutation in which one nucleotide is replaced by a different nucleotide. The term can also refer to the replacement of one amino acid in a protein with a different amino acid.

Base substitutions are the simplest type of gene-level mutation, and they involve the swapping of one nucleotide for another during DNA replication. For example, during replication, a thymine nucleotide might be inserted in place of a guanine nucleotide.

Substitution mutations can be good, bad, or have no effect. They cause three specific types of point mutation: silent, missense, and nonsense mutations.

Answer:

to provide insulation

Explanation:

The medullary index is the proportion of the diameter of the hair medulla in regard to the diameter of the entire hair: The equation to calculate the medullary index is medulla diameter/hair diameter. In animals, the hair medulla is generally thicker compared to humans (medullary index approximately 0.5 and 0.33, respectively). The thicker the diameter of the hair medulla, the better is the insulation.

Answer:

[tex]\boxed {\tt 16 \ m/s}[/tex]

Explanation:

Speed can be found by dividing distance by time.

[tex]s=\frac{d}{t}[/tex]

The rabbit travels 80 meters in 5 seconds.

The distance is 80 meters and the time is 5 seconds.

[tex]d= 80 \ m \\t- 5 \ s[/tex]

Substitute the values into the formula.

[tex]s=\frac{80 \ m }{5 \ s}[/tex]

Divide.

[tex]s= 16 \ m/s[/tex]

The rabbit's speed is 16 meters per second.

Answer:

The heating of the earth, which in turn heats the atmosphere, is responsible for the motions and movements of the air in the atmosphere. The faster molecules move, the hotter the air. As the molecules heat and move faster, they are moving apart.

Explanation:

Answer:

As you move higher off the ground, it gets colder *and vice versa*.

Explanation:

When we move off the ground, density is pulled down to the ground due to gravity. Therefore, it gets colder. It's also because of our atmosphere. (Vice versa, of course)

P.S. Density and gravity are also key parts of climate change, keep that in mind.

·have cell wall

cell wall is present in plant and fungi due to protection

but not in animals due to locomotion mode of life

Fungi have cell walls characteristic which fungi share with plants but not animals, hence option C is correct.

When compared to animals, fungi need prepared organic substances for energy because they are heterotrophic organisms without chloroplasts.

Fungi are eukaryotic organisms, just like plants, and have nuclei in each of their cells. Like plants, fungi lack a cell wall and vacuoles, however, they do have a material called chitin in their cell walls that plants do not. In numerous important respects, fungi are also similar to animals.

Eukaryotic, non-vascular, immobile, heterotrophic creatures are fungi. They could be filamentous or unicellular and spread spores to reproduce. The phenomena of generational alternation are seen in fungi.

Therefore, in comparison to plants, fungi have vacuoles and a cell wall.

Answer: The options are not given, here are the options.

a. located in the space outside the nucleus.

b. spread evenly throughout an atom. c. concentrated at multiple sites in an atom.

d. concentrated in the center of an atom.

The correct option is D.

concentrated in the center of an atom.

Explanation:

In an atomic model, the atomic particles has the nucleus which is located at the center of the particle. This nucleus contain positive charge which is called proton at the center and the neutrons(no charge). The electrons is located out side the particle she'll or nucleus and atomic particles become neutral because the number of protons is equal to the number of electrons which is negatively charge orbiting outside the nucleus.

Answer:

There is no image attachment, however, this question can be answered based on general understanding of enzymes. The answer is:

Temporary bonding occurs between the active site and the substrate, causing a conformational change.

Explanation:

Enzymes are proteinous molecules that acts as catalyst in biochemical reactions by speeding up the rate of reactions. According to this question, lactase is an enzyme that acts on lactose sugar and breaks it down into its monomeric unit (glucose and galactose).

All enzymes possess an active site, with which they bind to their substrate. In this question, the lactose (substrate) approaches the active site of lactase (enzyme), what occurs first is that a temporary bonding occurs between the active site and the substrate, causing a conformational change in the shape of the enzyme.

b. seasonal temperature changes.

There are 1000 calories in 1 Calorie (notice the difference in the capital C) on our food labels the Calories are given. Cellular respiration ; the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen, begins with a chemical pathway called glycolysis

Explanation:

Hope this helped, Have an amazing, spooky Halloween!!

The relationship between the calorie on a food label with the calorie produced in a cellular respiration is ;

When labeling food to indicate the nutrients contained in the food ( especially canned foods ) the amount of calories contained in the food is indicated and for every Calorie ( 1 calorie ) indicated on the label represents an equivalent of 1000 calories found in cellular respiration.

Hence we can conclude that 1 Calorie indicated on a food label is an equivalent of 1000 calories produced in a cellular respiration.

Explanation:

Meiosis creates four haploid cells from a diploid parent cell. These haploid cells are the sex cells - sperm cells and egg cells.

Since these cells are haploid (containing 23 chromosomes, half the amount of chromosomes as the parent diploid cells), when they fuse during fertilization, they form a diploid zygote containing 46 chromosomes.

Alvinella pompejana is known as the Pompiee worm. This organims is found in the deep hydrothermal vents in the Pacific ocean. Thus, the correct option is A.

Alvinella pompejana, the Pompeii worm is a species of the deep-sea polychaete worm. It is an extremophile found only at the hydrothermal vents of the Pacific Ocean, discovered in the early 1980s off the Galápagos Islands by the French marine biologists.

The Pompeii worm (Alvinella pompejana) is a deep-sea polychaete vermiform extremophile. This organism can survive at extreme conditions. It is possible because of their bacterial coating which redistributes the heat to keep the worm cool. This bacteria not only help regulate the temperature of the worm but they also break down minerals from the vent to aid their host.
