3.What two cell structures do protists have that bacteria do not?

4. Do all microbes cause disease? Explain

Answers

Answer:

Plant cells have a cell wall and chloroplasts; animal cells do not have either of these structures.

Explanation:

A major difference between a plant cell and an animal cell is presence of chloroplasts in plant cells. Another key difference between plant and animal cells is the presence of a cell wall in plant cells. Both structures are absent in an animal cells.

The cell wall surrounds the plasma membrane of plant cells. This helps to provide the required tensile strength and protection against mechanical and osmotic stress.

Cell walls also help plants to maintain shape and rigidity.

Answer:

1) Plant cells have a cell wall to strengthen the cell

2) Chloroplasts are the site of photosynthesis (turning light energy in sugar) so there would eb a lot more in the leaves that get sunlight than the roots which are underground and receive no sunlight

3) Mitochondria and nucleus

4) No. Some microorganisms are useful to humans, such as the bacteria that create yoghurt, or fungi such as penicillin which are antibiotics, which help us fight bacterial infections

what would happen to dietary protein if hcl were not being produced in sufficient quantities?

Answers

Dietary protein will not be digested if Hcl were not being produced in sufficient quantities.

In the stomach, there are some glands found on the stomach lining that helps to release hydrochloric acid (HCl). Their major role is to dissolve food and produce an acidic medium.

The acidic media promotes and improves the conversion of pepsinogen to pepsin. Pepsin acts as an enzyme that supports protein digestion.

Protein digestion requires a pH of around 1.8 which can be achieved by the secretion of HCl.

As a result, if HCI is not released in the stomach in sufficient quantities, pepsin will not be activated and it would have a detrimental impact on protein digestion.

Therefore, we can conclude that dietary protein will not be digested if Hcl were not being produced in sufficient quantities.

Which statement describes what a thermos does?
A. A thermos makes things warmer
B. A thermos stops heat transfer
C. A thermos makes things cooler
D. A thermos slows heat transfer

Answers

The best answer I suppose would be A. A thermos helps keeps things hot and doesn’t allow heat to escape. Hope this helps! :)

A thermos slows down the process of heat transfer as it minimizes the process of conduction and convection.

What is conduction?

Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.

In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules ,

When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state conduction 2) transient conduction.According to the type of energy conduction is of three types:

1) heat conduction

2) electrical conduction

3)sound conduction
