A cell with 12 chromosomes undergoes mitosis, How many daughter sells are

pantera1 [17]

You can draw a free body diagram with two 250N forces acting on the human, one from each side. The net force is 0 because the two applied forces cancel each other out since they are in opposite directions.

If a person had not drunk any water for 8 hours before collecting a sample, would you expect his/her urine to have a high or low

Mrrafil [7]

Answer:

The person’s urine will have a high specific gravity

Explanation:

A high specific gravity is characterized by an increased concentration of solutes in the urine of am individual. A low specific gravity is characterized by a low or decreased concentration of the solutes.This is usually due to dehydration as a result of environmental conditions or tedious physical activities.

This explains why a person who had not drank any water for 8 hours and is dehydrated before collecting a sample is thought to have a urine with a high specific gravity

According to the Endosymbiotic Theory, infoldings in the cell membrane of an ancestral prokaryotic cell gave rise to endomembran

Ad libitum [116K]

Explanation:

<u>False:</u> C) The ER provides separate microenvironments for each of the modifications that must take place to proteins.

The golgi apparatus comprised of several components called cisternae, these function as different microenvironments, where further modification proteins and lipids into functional biomolecules occurs.

During protein synthesis, transcription occurs in the nucleus, followed by translation within ribosomes, the newly synthesized proteins enter endoplasmic reticulum where they undergo folding and modification. Within the golgi body, the proteins are tagged and parceled into lysosomes for export.

Further Explanation:

The endoplasmic reticulum is a membrane system within the cytoplasm that extends from the outer nuclear membrane. Apart from increasing the surface area within the cell, this continuous system also carries out protein folding, synthesis and transport. In the endoplasmic reticulum or ER, some sections called the smooth ER, do not contain ribosomes, and may contain lipids, enzymes, and other proteins. Other sections bound to ribosomes, are called the rough Er. As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen. The proteins undergo major modifications and are packed into vesicles.

Golgi bodies are flat, disk-like membranous regions. Proteins traverse the organelle by first having their vesicles bind to the cis face or receiving end. Like a post office, the golgi complex, or golgi body recognizes specific signal sequences, targets and further modifies and packages these compounds into lysosomes for delivery to their final destination. Proteins here undergo peptide processing and glycosylation

What was the purpose of the Apollo space mission?

Flura [38]

Explanation:

Apollo's Goals

The national effort that enabled Astronaut Neil Armstrong to speak those words as he stepped onto the lunar surface fulfilled a dream as old as humanity. Project Apollo's goals went beyond landing Americans on the moon and returning them safely to Earth. They included:

Establishing the technology to meet other national interests in space.

Achieving preeminence in space for the United States.
Carrying out a program of scientific exploration of the Moon.
Developing human capability to work in the lunar environment.
