Answers

Answer:

Impotence, which is another word for erectile dysfunction, simply refers to difficulty getting or keeping an erection that's firm enough for sexual activity. Sterility or infertility means that the body doesn't produce “good” sperm—that is, not enough sperm are produced, or the sperm don't function as they should.

Amino acids are named after two of their functional groups: the amino group (NH2), which acts like a base, and the carboxyl group (COOH), which acts like an acid. Amino acids also contain a third functional group, often called the R group. In alanine, the R group is a methyl group (CH3). In serine, the R group is a methyl alcohol (–CH2OH).

A molecule of alanine is shown next to a molecule of serine. Each molecular structure has an amino group (NH2) on the left side, and a carboxyl group (COOH on the right side.

What functional groups will be joined together if alanine and serine molecules combine to form a single molecule?
A molecule of alanine is shown next to a molecule of serine. Each molecular structure has an amino group (NH2) on the left side, and a carboxyl group (COOH on the right side.
A. an amino group and a carboxyl group
B. two amino groups
C. an amino group and a methyl group
D. a hydrogen atom and an methyl group

Answers

The functional group alanine and serine molecules when they combine to form a single molecules an amino group and a methyl group.

What is amino acids?

Amino acids are molecules that join together to form proteins. Amino acids are the building blocks of living organisms. Proteins are broken down into amino acids which is the end product of protein digestion and it is easily absorbed into the body. Amino acids help to build cells, synthesize hormone and neurotransmitters.

Amino acid is divided into essential and non essential amino acids.

The essential amino acids are not synthesised by the body but they are taken up as food supplements and they include that include leucine, isoleucine, histidine, lysine, methionine, threonine, phenylalanine, tryptophan, and valine.

Non-Essential Amino Acids are Amino acids that are synthesised by our bodies. Examples include aspartic acid, glutamic acid, alanine, glycine, tyrosine, serine.

Therefore, The functional group alanine and serine molecules when they combine to form a single molecules an amino group and a methyl group.

breathing involves the movement of diaphragm and Rib cage

true or false

Answers

Answer:

True

Explanation:

It's a true statement as,

When we inhale the diaphragm moves downwards and the rib cage moves upwards and outwards to let enter the outside air containing oxygen come in.While we exhale the diaphragm comes to its position and the rib cage move downwards and inwards to let out the inside carbon-dioxide and other games out.

Hence, we can conclude that breathing involves the movement of diaphragm and Rib cage.

Yes,very true! This is very true because out lungs are around our rib cage,and our lungs is where we breath. For example,right now take a breath in.....Hold.... and out. And one more time. Your lungs are moving in your rib has you do that!

Hope this explains better :)

Muscles that move the wrist and hand originate on which bone(s)?

Answers

Answer:

a. Humerus

Explanation: is correct

Muscles that move the wrist and hand originate on bone carpals. The correct option is d.

What are carpals?

The carpal bones are wrist bones that connect the distal portions of the forearm's radial and ulnar bones to the bases of the five metacarpal bones of the hand. There are eight carpal bones that are divided into two rows: proximal and distal.

The wrist is made up of eight tiny bones (carpal bones) and two large bones in the forearm — the radius and ulna. Each finger has one hand bone (metacarpal) and three finger bones (phalanges), but each thumb has one metacarpal bone and two phalanges.

The carpals are eight bones present in the wrist of the hand. It helps in moving the wrist, and it also attaches the hand to the wrist.

Therefore, the correct option is d, carpals.

What happens when the chemical bond that holds the third phosphate is broken?

Answers

The chemical bond between the second and third phosphate groups is a high energy bond. When that bond is broken, energy is released, producing ADP (adenosine diphosphate).

The second and third phosphate groups' chemical connection is a high energy bond. ADP is created when that link is disrupted and energy is released (adenosine diphosphate).

What is phosphate bond?

The structural structure of nucleic acids, including DNA and RNA, is composed of the sugar-phosphate backbone.

This molecule's directionality is determined by this backbone, which is made up of alternating sugar and phosphate groups.

Nucleotides make up DNA and RNA, and they are connected to one another in a chain via chemical interactions between their neighboring nucleotides' phosphate groups and sugar bases.

Therefore, The second and third phosphate groups' chemical connection is a high energy bond. ADP is created when that link is disrupted and energy is released (adenosine diphosphate).

Farmers were unable to coax wheat from the parched earth. Huge swaths of plowed land, unanchored by native grasses, were left exposed to the region's strong winds, resulting in years of dust storms that earned the decade the title the Dirty Thirties. Facing poverty and dust inhalation, four hundred thousand people fled the region. Years later, a resurgence of dust storms occurred during another drought. However, the extent of the damage during the Filthy Fifties (as the decade came to be called) offered a contrast to the Dirty Thirties. Not only was the drought shorter, but the land was less vulnerable. In the intervening years, the federal government had restored prairie grasses, while farmers had also applied techniques to prevent soil erosion.What is the main idea of the passage?Questionsanswered20Timeelapsed001204HRMINSECSmartScoreout of 10076Need a break?
