PLEASE HELP ITS DUE IN 30 Minutes!!! Which Two Statements Explain Why A Student Standing At The Top Of

Answers

Answer 1

Answer:

b. The step stool exerts a force on the student in the opposite direction of gravity.

c. A student exerts an upward force on the step stool equal to the gravitational force

Explanation:

It is true that gravity is the force that pulls the objects down to the earth but there are some forces that oppose the statement.

In the given situation, the student is unable to fall down from step stool is because of two forces one, the force exetred by step stool on student and two, the force exerted by the student on step stool.

The step stool exerts a force on the student in the opposite direction of gravity that gives stability to the step stool and an upward force on the step stool equal to the gravitational force helps the student to climb the stool.

Hence, the correct option are b and c.

• A. Law of Independent Assortment
B. Law of Dominance
.
C. Law of Segregation
D. Law of Multiple Alleles

Answers

Answer:

c. low of segregation is the correct answer

This principle states that alleles separate during gamete formation is  Law of Segregation.

Option C is correct.

How do we explain?

The Law of Segregation states that during gamete formation, the alleles of a gene segregate (separate) from each other, so that each gamete receives one allele from each parent and this  means that each gamete will contain only one of the two alleles for a particular gene.

The Law of Segregation was first proposed by Gregor Mendel in 1865.

Option C is correct.

After one round of DNA replication, _____________ of the DNA will contain only 14N, _____________ of the DNA will contain only 15N, and _______________ of the DNA will be of an intermediate density.

Answers

Answer:

After one round of DNA replication, none of the DNA will contain only 14N, none of the DNA will contain only 15N, and all of the DNA will be of an intermediate density.

Explanation:

In order to rule out the conservative model of DNA replication and discover that it in fact a semi-conservative model, this technique was employed to check for what ratio of N15 and N14 was present in cells that had undergone the process of replication. The former would've resulted in equal densities of both N14 and N15.

Kendra wishes to build a model of a carbohydrate molecule, ideally containing as many monomers as possible. Which set should she choose?

Answers

Answer:

Polysaccharides.

Explanation:

Polysaccharides are sets of carbohydrates formed by the union of hundreds and miles of carbohydrate molecules, the set having the largest possible number of monomers.

Carbohydrates are energetic molecules that are also present as structural molecules, being essential for the maintenance and functioning of the organism. Carbohydrates can be presented in monosaccharide, disaccharide and polysacride sets.

Polysaccharides

A polysaccharide is a type of carbohydrate. It is a polymer made up of many sugar subunits, called monosaccharides. The main functions of polysaccharides are structural support, energy storage, and cellular communication. For example: cellulose, chitin, glycogen, starch, and hyaluronic acid. Carbohydrates are energetic molecules that are also present as structural molecules, being essential for the maintenance and functioning of the organism.

diseases can alter an organisms homeostasis. when you get sick and have a fever, what internal condition has changed

Answers

Answer:

Homeostatic Imbalance and Disease. Sometimes homeostats fail to perform properly. This can cause homeostatic imbalance, a condition in which variables in the internal environment are no longer maintained within normal ranges.

Explanation:

when you get sick and have a fever, what internal condition has changed it ultimately change the body's homeostasis.  The body is unable to maintain the equilibrium of internal environment will lead to homeostatic imbalance.

What is homeostatic imbalance ?

Homeostasis is mechanism where our body maintain balance and equilibrium which can be characterized physiologically or psychologically.

It is extremely important as it has a vital in maintenance of glucose levels, osmoregulation, regulate hormones, and body temperature.

It is otherwise called as thermoregulation as the body temperature is maintained by this process.

For example a person with cold, shiver to warm up while a person with high body temperature, sweat a lot in order to attempt cool their body.

Any kind of disruption lead to imbalance in equilibrium of the body called as homeostatic imbalance.

For instance, a homeostatic imbalanced person may not sweat properly, leads to overheat resulted in  hyperthermia and heatstroke.

When can a cell swell up ? ​

Answers

Answer:

Explanation:

The cell swells up when the concentration of water molecules outside the cell is more than the concentration of water molecules inside the cell. It is because the water moves from a region of higher concentration to a region of lower concentration due to osmosis. So the water molecules outside the cell will move inside the cell ( from higher concentration to lower concentration) and it will swell up.

This solution is known as hypotonic.

So the correct option is B.

Hope this helps

plz mark as brainliest!!!!!!

Answer: A

Explanation: When there is a higher concentration of water in the cell more than the surrounding area, then the cell tends to swell up, this is due to osmosis.

Can this condition cause significant harm to her health?

If so, what kind of health problems will she develop?

Are there ways to treat this condition?

Explanation:

After Hugh analyzed his daughter's DNA he thought that her DNA had certain malfunctioning genes. He thought those genes were responsible for this condition of his daughter.

What is DNA?

DNA is defined as deoxyribonuclic acid and it is a polymer made up of two polynucleotide chains that arranged in foiled structure to form a double helix carrying genetic information for the various processes such as growth development  functioning and reproduction.

Friedrich Miescher discovered DNA in the year of 1860.

The main function of DNA is to carry information from one generation to another generation this is the reason due to which DNA is also known information molecule.

In our body DNA is found in the nucleus of the cell and it is known as nuclear DNA.

The shape of DNA is double helical structure.

Siblings share only about 50% of same DNA due to the reason of recombination.

The life span of DNA is 521 years.

Therefore, after Hugh analyzed his daughter's DNA he thought that her DNA had certain malfunctioning genes. He thought those genes were responsible for this condition of his daughter.

Which of the following statements is true? The rigidity of a cell wall causes plants to be sedentary. Primary cell walls are more rigid than secondary cell walls. Since they have cell walls, plant cells do not have cell membranes. A wilting plant will have a full central vacuole.

Answers

Answer:

The correct answer is : The rigidity of a cell wall causes plants to be sedentary.

Explanation:

Plant cells have an extraordinary organelle present outside of cell membrane known as a cell wall, which makes the cell more rigid and strong. The primary capacity of a cell wall is to provide structural support.

It additionally gives the plant a specific level of inflexibility, which permits it to become extremely tall without falling under its own weight. The drawback is the absence of versatility Which is the reason plants are inactive and incapable to move.

Thus, the correct answer is : The rigidity of a cell wall causes plants to be sedentary.
