In your research, you have discovered that protein x is often ubiquitinated in people with a certain disease. what would you pre
inna [77]
The level of protein X in these patients will be low due to degradation in the proteasome. Ubiquitnation process occur when ubiquitin is attached to a particular protein and the protein become deactivated. Ubiquitin is a small biochemical molecule which marks out proteins for destruction. Any protein that have ubiquitin attached to it will be transported to the proteasome for destruction by degradation.

Match the prokaryotic cell structures to the characteristic of life.
djverab [1.8K]

Answer:

1. Nucleoid: Prokaryotes do not have well defined nucleus. Instead, naked DNA or genetic material is found in the these cells which keeps floating freely in the region of cytoplasm called as mucleoid (nucleus-like). DNA carries the genetic information required for growth, development, metabolic activities and reproduction.

Hence, it must match with b. reproduction: DNA ensures that future generations will be similar to parents

2. Cell wall: Cell wall is the outermost layer surrounding the plasma membrane. It is composed of polysaccharides and is found in bacteria, fungi, and plant cells. In bacteria, it is generally composed of peptidoglycans. Antibiotic such as penicillin acts on the cell wall and creates pores in it which kills the bacteria.

Hence, it can be correctly matched with d. homeostasis: taking an antibiotic, such as penicillin, creates holes in the cell wall of some bacteria, so they lose water and die

3. Flagellum: It is a thread or hair like structure which serves the purpose of locomotion in the cells specially in bacteria, protozoa, spermatozoa etc. In bacteria, it helps in moving in the direction of food and moving away from inhospitable environment.

Hence, it can be correctly matched with e. responding to stimuli: move away from a less hospitable environment or towards a more hospitable environment.

4. Pilus: It is a hair like but rigid structure that protrude from the cell surface of the bacteria. It helps in the process of conjugation by forming a conncetion between cell surface of two bacteria.

Hence, it can be correctly matched with a. reproduction: exchanging genetic material in process of conjugation

5. Ribosomes: Ribosomes serve as the site of protein synthesis in the cell. Bacterial ribosomes are composed of two sub-units with sedimentary constant of 50S and 30S.

Hence, it can be correctly matched with c. maintaining homeostasis: protein is needed for enzymes and repairing structures

6. Cytoplasm: It is gel like material found within the cell (excluding nucleus in case of eukaryotes). All the metabolic activities of the cell generally take place in the cytoplasm of the cell.

Hence, it can be correctly matched with f. homeostasis: using energy, all chemical reactions are performed in the cytoplasm

Marissa is testing a hypothesis through experimentation. She believes that immersing ocean coral in carbonic acid will slow the
motikmotik

Answer:

The answer choices to this question are:

A) She releases cement particles into a random number of the coral samples.

B) She uses three different types of coral to establish her dependent variables.

C) She treats the coral samples identically with varying levels of carbonic acid.

D) She obtains her coral samples from coral reefs surrounding different continents.

Best Answer is:

A) She releases cement particles into a random number of the coral samples.

Theory:

It has been researched that ocean acidification caused by carbon dioxide emissions causes a decrement in the coral reef growth and this will keep slowing down unless steep and rapid reductions in greenhouse gas emissions are made. And the Coral reefs offered economic opportunities would advantage the surrounding communities from fishing and tourism.

i did this question so thats why i know the answer choices

hope this helpsss
