Answer:

The correct answer is option C. "The magnetic field of earth keeps changing because of the suns activity"

Explanation:

The magnetic field of Earth is not a steady force, and is affected by external forces such as the suns activity, particularly during strong solar/geomagnetic storms. The changes in the magnetic field of Earth explains why the auroras Are sometimes seen at northern Ohio. The auroras are created by energetic electrically charged particles accelerating along the magnetic field, if the location of the magnetic filed changes, the location of the auroras change as well.

4. Which of the following statements best describes how proteins and enzymes move within a cell?
Artyom0805 [142]

Answer:

The movement of proteins and enzymes within a cell is facilitated by intracellular receptors.

Explanation:

Proteins and enzymes (which also are proteins) move inside the cell through intracellular receptors. These receptors are proteins capable of binding other molecules such as proteins and hormones in order to transport them to different cellular locations. Thus, intracellular receptors are key players in signaling pathways that trigger signaling events to regulate a particular function, for example, activating gene expression by transporting proteins to the nucleus.

Which statement is not true about invertebrate animals?
Phoenix [80]

Answer:

e) Invertebrates lack a nervous system

Explanation:

One of the main characteristics of invertebrates is that they don't have a backbone. Backbones belong to the skeletal system. A totally different story is the nervous system which runs inside the backbone. Although the more complex nervous systems appear in vertebrates the simply fact of having eyes like crabs or insects implies having a nervous system that can control them.

A biochemist isolates and purifies various molecules needed for DNA replication. When she adds some DNA, replication occurs, but
galina1969 [7]

Answer:

The correct answer is DNA ligase.

Explanation:

DNA Ligase is an enzyme with links 2 strands of DNA by creating a bond between the phosphate group of 1 strand and deoxyribose group of the other strand of DNA.

In cells, it is used to join the Okazaki fragments together which are formed on the lagging strand during the process of DNA replication.

Okazaki fragments are tiny pieces of DNA nucleotide which are formed in a discontinued manner  but latter they are joined by DNA ligase enzyme.

A protein that contains more isoleucine, phenylalanine and leucine than asparagine, lysine and arginine is most likely ________.
Snezhnost [94]

Answer:

The correct answer is: Hydrophobic, Hydrophobic.

Explanation:

  • Proteins are made up of polypeptide chains which are formed by the polymerization of amino acid molecules, linked together by peptide bonds.
  • The amino acids can be broadly classified into non-polar and polar.
  • The non-polar amino acids can be defined as those amino acids whose side chains possess hydrocarbon molecules only. They do not possess any charge and are incapable of forming hydrogen bonds with water molecules. They tend to avoid water and so they tend to remain buried into the interior of a protein. Examples can be illustrated as Leucine, Valine, Isoleucine, Phenylalanine, etc.
  • The polar amino acids can be defined as those amino acids whose side chains either possess a charge (positive or negative) or a hydroxyl group which is capable of forming hydrogen bonds with water molecules. As they tend to form hydrogen bonds with water molecules they are usually found on the surface of the proteins. Examples can be illustrated as Lysine, Arginine, Serine, Asparagine, etc.
