Answer:

The correct answer is - Cyanobacteria; Horizontal gene transfer

Explanation:

According to the endosymbiotic theory it is believed that the eukaryotic plastids (mitochondria and chloroplasts) have developed from symbiotic bacteria, such as cyanobacteria and alpha-proteobacteria.

During this symbiotic process, some genetic material may have been move in between the symbiotic counterparts in a process called Horizontal gene transfer or lateral gene transfer.

thus, the correct answer- Cyanobacteria; Horizontal gene transfer

Nimfa-mama [501]

Answer:

CHK2, p53, p21, cell cycle progression.

Explanation:

In a normal cell with no LFS mutation, during the G1 stage of cell cycle progression, the CHK2 activates if there is damage in the DNA. CHK2 activates p53, which is a tumor suppressor protein that will hold the cell cycle in G1/S until the DNA is repaired. The p53 protein activates p21, a protein that binds to CDK2 and stops the cell cycle. The cell cycle will continue once the damage is repaired.

mr_godi [17]

Answer:

16

Explanation:

Aquaporin 1 is a protein coding which exists as a tetramer {a tetramer is an oligomer formed from four monomers}. It functions as a molecular water channel proteins and also a non-selective cation channels. Each monomer in a complete aquaporin complex can form four (4) water molecules. As such, there will be sixteen (16) molecules of water present in an Aquaporin-1 Complex.

State the major processes of the urinary system and describe the activity of each process.
Dennis_Churaev [7]

Answer:

The urinary system removes excess substances and waste products from the metabolism from the body through the urine, contributing to the maintenance of homeostasis, the chemical composition of the internal environment. Urine is produced in the kidneys, passes through the ureters to the bladder, where it is stored and is released into the exterior through the urethra.

The kidneys perform the main work of the urinary system comparing with the other parts of the system, acting primarily as passageways and storage areas. With the filtration of blood and the formation of urine, the kidneys contribute to homeostasis of body fluids in a number of ways, such as: Regulation of the ionic composition of blood; Maintenance of blood osmolarity; Regulation of blood volume; Blood pressure regulation; PH regulation of blood; Hormone release; Regulation of blood glucose level; Waste excretion and toxic substances.

Ureters - They are two tubes that carry urine from the kidneys to the bladder. The ureters are capable of performing rhythmic contractions called peristalsis. Urine moves along the ureters in response to gravity and peristalsis.

Bladder - The urinary bladder acts as a temporary reservoir for urine storage. It is a hollow, elastic muscular organ that in men is directly anterior to the rectum and in women, is located in front of the vagina and below the uterus.

Urethra - is a tube that conducts urine from the bladder to the outside, being lined with mucosa that contains a large amount of mucus-secreting glands. The urethra opens outwards through the outer ostium of the urethra.

Protein synthesis is a multistep process. put the steps of protein synthesis in sequential order.
wlad13 [49]

Answer:

Replication - Transcription - Translation

Explanation:

Replication duplicates the DNA so that happens first. Then in transcription converts the DNA to mRNA which goes to the cytoplasm to make proteins. In translation proteins are made when codons and anti codons join to make amino acids which create the proteins.
