The sequence of in a Dna molecule determines the protein that will be produced

Answers

Answer 1

Answer:

Answer:

True

Explanation:

The DNA sequence determines the protein that is going to be produced. The first step is the transcription where DNA sequence is transcribed to mARN. After the mARN is formed this will go out of the nucleus and into the cytoplasm. In the cytoplasm the mARN, together with the tARN and the ribosome will make a protein by a process called translation. In this process the ARN sequence is read to give and join the amino acids that are required to form the protein.

How are atoms in a compound held together?

Answers

The atoms in a compound are held together by a chemical bond. The chemical bonds can be either covalent bonds or ionic bonds. Both the bonds are considered very strong bonds. These bonds are mainly formed by sharing of electrons or in the case when one of the elements making the compound donates electron to the other element. The nucleus of each atom attracts to form a strong bond. This property of attraction between the nucleus of the atoms actually helps in forming the chemical bonds.

The atoms in any compound are held together by some bonds. These bonds are chemical bonds.

A chemical bond is an attractive force which hold the various components of a compound together. It provides stability to the compound by loss of energy. The more strong a chemical bond, the stronger is the chemical compound.

A compound is the bonding of two or more atoms tied together. It can be a molecule or a group bound together. To or more different atoms which are together but not covalently bound is a mixture.

Types of chemical bonds found commonly are:

1. Ionic bonds

2. Hydrogen bonds

3. Covalent bonds

4. Polar bonds

Hence, the atoms in a compound are held together by chemical bonds.

What type of genetic material does a Blue whale contain?

Answers

Answer:

The blue whale is very genetically diverse. There are four subspecies of blue whale: B. musculus musculus, B. musculus intermedia, B. musculus indica, and B. musculus brevicauda. Very little is known about the genetic differences between these species besides appearance and weight. The subspecies don’t usually mix because of location.

In the 19th and early 20th centuries, almost all of the blue whales were killed for their baleen plates. They are now increasing in population, and scientists would like to try to see what they can do to continue to increase the population.

________ sweat glands are widely distributed across the body surface, ________ glands are located wherever hair follicles exist, and ________ sweat glands are found only in a few areas.

Answers

Answer:

eccrine glands, sebaceous glands , apocrine glands

Explanation:

Eccrine sweat glands are located on all over the body and secret water and electrolyte to regulate body temperature and excretion of waste substances too.

Sebaceous glands are located at the place where hair is present except the palms of the hands and soles of the feet.

Apocrine glands are located in armpits, the groin, and around the nipples of the breast the sweat releases from the apocrine have some odor too.

In a car, how does an air bag minimize the force acting on a person during a collision?

Answers

Answer:

It increases the time it takes for the person to stop.

Explanation:

Due to the laws of motion the airbag causes force in the other direction while the person is moving forward, thus trying to equal out the force acting apon the person to make them stay in place.

Question 1 All living organisms contain carbon atoms. Which of the following is an important characteristic of carbon?

Question 1 options:

Carbon atoms are highly reactive and form unstable bonds with any available atom.

Carbon atoms can bond with any other atom, but they cannot form bonds with other carbon atoms

Carbon atoms are very stable and do not easily form bonds with other atoms

Carbon atoms can bond with many other kinds of atoms to form very stable molecules.

Question 2
Any chemical that contains carbon bonded to at least one other atom, usually hydrogen, is known as a

Question 2 options:

Carbohydrate

Fatty Acid

Organic Molecule

Question 3
How many valence electrons are generally needed to fill the outer shell of most atoms?

Question 3 options:

4

6

8

Question 4
The macromolecules in biochemistry are proteins, carbohydrates, lipids and nucleic acids. What main elements do all of have in common?

Question 4 options:

Carbon and Sulfur

Carbon and Hydrogen

Oxygen and Nitrogen

Oxygen and Phosphorus

Answers

1. The correct answer is 4. Carbon can bond to 4 other atoms, exponentially increasing its ability to make different molecules.

2. The correct answer is 3. An organic compound (or molecule) is any atom (usually hydrogen) that bonds with carbon.

3. The correct answer is the third option (8 electrons). Valence electrons in the outer shell are those can form a chemical bond. When (most) atoms have 8 electrons in their outer shell, they are then considered to have maximum stability.

4. The correct answer is 2. These macromolecules all contain carbon and hydrogen, making them organic compounds.

1 - Carbon atoms can bond with many other kinds of atoms to form very stable molecules. 2 - organic molecules . 3 - 8 (full shell) . 4 - i'd say Carbon and Hydrogen
