1. Why do plant cells have a cell wall in addition to a cell membrane?
2. Think about the function of chloroplasts. Would you expect to find
more chloroplast in the cells of leaves or the roots of a plant?
3.What two cell structures do protists have that bacteria do not?
4. Do all microbes cause disease? Explain
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

how much energy is released when 23 g of steam at 100 Celsius is condensed into liquid water?
H = mc∆T
H = 23g * 4.2J/g°C *(100°C - 0°C)
H = 9660 J
H = 9.66 KJ.
The energy released is 9.66 KJ.

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
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

which level of protein structure do beta-pleated sheets and alpha helices represent?
A mid-ocean ridge separates the Pacific plate and the Nazca plate off the western coast of South America.Which statement best describes the relative motions of these two plates?
Answer:
See below
Explanation:
The two plates are called DIVERGENT which means the two plates are moving away from each other. The separating motion can allow magma to come to the surface creating the mid-ocean ridge.

Two scientists work together on an experiment, but they have different hypotheses. When scientists look at the experimental results, they interpret the data in different ways and come to different conclusions. Which of the following does this situation best illustrate?
Answer:
The correct answer is option D, confirmation bias.
The correct answer is option D, confirmation bias.Confirmation bias is the tendency to interpret data in a way that confirms the already designed hypotheses.
The correct answer is option D, confirmation bias.Confirmation bias is the tendency to interpret data in a way that confirms the already designed hypotheses.As the two scientists interpret the data (or experimental results) in different ways to adhere to the different hypotheses. this is also called indicative of cognitive bias. This is also called inductive reasoning where the premise is viewed as evidence for the validity of the conclusion.

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