What molecules in the cell membrane help move molecules from a low to a high concentration gradient?

Answers

Answer 1

Answer:

In simple diffusion, small noncharged molecules or lipid soluble molecules pass between the phospholipids to enter or leave the cell, moving from areas of high concentration to areas of low concentration (they move down their concentration gradient).

If i were to jump off a cliff without bending my knees, would i break my legs and/or my spine??

Answers

I feel like you would break your legs because of the impact and maybe ankels

Answer:

If you were to jump off a cliff, you would break both your legs and your spine.

Explanation:

Since you would be landing on your feet when crashing onto the ground/rocks/etc., you would potentially (actually, 99.99% chance) become paralyzed and not be able to move your legs and spine. The five sciatic nerves join at the base of the spine and extend down the back of each leg to the toes. The sciatic nerves connect the spinal cord to many of the leg and foot muscles.

Therefore, since you would be landing on your feet, you damage not only the feet and legs, but also your entire spine, which is also connected to your brain (the spinal nerves that is).

A. Fat

B. Steroids

C. Sugar

D. Waxes

Answers

Pretty sure the answer is Sugar, Correct me if I'm wrong

Sugar is not a lipid, but it is a carbohydrate. Thus, option C is correct.

What is lipid?

Lipid is type of biomolecule, consisting, fats, steroids, waxes, and fat soluble vitamins such as A, D, E, K and others. It is an organic molecule which is hydrophobic or amphiphilic molecule which is insoluble in the water.

Fatty acids are included in the class of carboxylic acids which has long hydrocarbon chain and terminal carboxyl group (COOH). As compare to other molecules found in food that are carbohydrates and proteins, lipids contain more than twice energy.

Lipids play significant role in cell signaling as lipid signaling, which is very vital part of it. It is also involved in immunity, hormones such testosterone, estrogen, cortisol. Fat soluble vitamins play an important role in nutrition.

Therefore, sugar is carbohydrate not lipid. Therefore, option C is correct.

b. It prevents acetylcholine from binding to its receptors.
c. It stimulates guanylyl cyclase in smooth muscle cells.
d. It blocks the enzyme that degrades cyclic GMP.
e. It binds to acetylcholine receptors on endothelial cells.

Answers

Answer:

The correct answer is option d, that is, it prevents the enzyme, which degrades cyclic GMP.

Explanation:

Oral therapy for erectile dysfunction is Viagra, which is the citrate salt of sildenafil, it works by preventing a specific phosphodiesterase type 5 or PDE5, which is the inhibitor of cGMP. During sexual stimulation, nitrous oxide is released in the corpus cavernosum causing the erection of the penis in males. The nitrous oxide then stimulates the enzyme guanylate cyclase that further makes the concentration of cGMP to elevate, this generates smooth muscle relaxation in the corpus cavernosum and permitting blood the inward flow of blood.

Viagra works by increasing the influence of nitric acid by preventing PDE5, which is accountable for the deprivation of cGMP in the corpus cavernosum. At the time of sexual stimulation, the discharging of nitrous oxide takes place, the viagra inhibits PDE5 causing the levels of cGMP to elevate in the corpus cavernosum leading to smooth muscle relaxation and continuous flow of blood to the corpus cavernosum.

What is a gamete?

It is the reproductive cell of an organism. They are haploid in nature. 

How many types of gametes are there?

There is a male gamete that is termed sperm (animals) or pollen grain (plants) and a female gamete that is termed ovum (animals) or egg (plants).

What kind of division occurs prior to gamete formation?

Meiosis, or reductional division, occurs prior to gamete formation.

What is its significance?

It ensures that after fertilization, the normal diploid number is maintained.

What kinds of cells undergo this division to produce gametes?

So yes photosynthesis uses light and water in the process of forming sugar.

Scientists describe the processes of photosynthesis and cellular respiration as "being interrelated". What is this statement most likely referring to?


A. The reactants of both processes are the same.

B. The products of both processes are the same.

C. The products of each process are the reactants to the other.

D. The processes occur at the same time.

Answers

Answer:

C. The products of each process are the reactants to the other.

The statement that photosynthesis and cellular respiration are interrelated means that the products of each process are the reactants to the other.

PHOTOSYNTHESIS:

Photosynthesis is the process whereby green plants obtain their food using energy from sunlight.

Photosynthetic process combines carbon dioxide (CO2) and water (H2O) to form glucose and oxygen gas.

CELLULAR RESPIRATION:

Cellular respiration is the process whereby living organisms obtain energy (ATP) by breaking down food molecules in their cells.

Cellular respiration uses oxygen to breakdown glucose, thereby, forming carbon dioxide and water.

Therefore, the statement that photosynthesis and cellular respiration are interrelated means that the products of each process are the reactants to the other.

Sex Linked Inheritance

Why are women often carriers of X-linked traits but rarely affected by them?

Answers

Answer:

See the answer below

Explanation:

Women are often carriers of X-linked traits but are rarely affected by the trait because they have two X chromosomes and the two have to carry the X-linked allele in order for them to be phenotypically affected, especially if the trait is a recessive one.

Unlike men that are XY and only require one X-linked allele in order to be affected for X-linked recessive traits, women need two alleles - one on each chromosome - in order to be affected. One of the X chromosomes of a woman usually comes from the woman's father and the other one from her mother. In order to be affected, a woman must inherit an affected chromosome from her father and her mother respectively, thereby reducing the probability of having the trait.

The X chromosome of a man usually comes from his mother. Hence, a man only needs to inherit an affected chromosome from his carrier mother to be affected for the trait, thereby increasing the probability of having the trait when compared to a woman.

This is not the case for X-linked dominant traits where both men and women have an equal chance of being affected.

Women carry two XX chromosomes in their cells. They carry the X chromosome but rarely gets affected by the trait because to be phenotypically affected they should carry X linked disease trait on both the X chromosomes.

Especially in the case when the trait is recessive then they should have two XX chromosomes which are linked to traits.

In the male, they have one X and one Y chromosome so they acquire an X chromosome and gets affected by it.

In male presence of one X chromosome from the carrier mother is enough to pass the trait. While in females to have X linked recessive trait they should have two alleles.

The woman does not get affected as one chromosome comes from the father and the other from the mother so to be affected the woman must acquire genes with traits from both parents.

Therefore, women are often carriers but are rarely affected by them.

Answers

Answer:

How can we explain why there is so much diversity of life on Earth today?

There are several key reasons for high biodiversity in tropical ecosystems. High NPP directly contributes to α-diversity by supporting more species with minimum viable populations, whereas enlarged populations of each organism increase overall mutation frequency and hence intraspecific genetic variation.
