Why is it a advantage for the thylakoid cell to have a round shape?

The roundness of the thylakoid provides it with a larger surface area for light to be absorbed and for the light-dependent stage of photosynthesis to occur.

What is incomplete dominance
Vikki [24]

Answer:

Incomplete dominance is when a dominant allele, or form of a gene, does not completely mask the effects of a recessive allele, and the organism's resulting physical appearance shows a blending of both alleles. ... Note that this is different from codominance, which is when both alleles are expressed at the same time.

The most important factor that determines the percent of oxygen saturation of hemoglobin is
erik [133]

Answer:

This question lacks options, options are:

a) The partial pressure of oxygen

b) Acidity

c) The partial pressure of carbon dioxide

d) Temperature

e) BPG

The correct answer is a. The most important factor that determines the percent of oxygen saturation of hemoglobin is <u>The partial pressure of oxygen </u>.

Explanation:

Hemoglobin is an oxygen transport protein. Partial Oxygen Pressure (PaO2), measures the pressure of dissolved oxygen in the blood, that is, it shows how well oxygen passes from the lungs into the bloodstream. A high partial pressure of oxygen in the blood produces an almost complete saturation of hemoglobin, which indicates the maximum amount of oxygen that combines, but when PaO2 is reduced, so is hemoglobin saturation, when saturation is below 90% hypoxemia occurs, that is, the level below normal blood oxygen levels.

You observe a high proportion of malarial infections in a small village located in Angola. Malaria is caused by the protozoan Pl
svet-max [94.6K]

Answer:

<em>B and C.</em>

Explanation:

The epidemiological triangle is an illustration of interaction among suitable hosts, disease agents, and the environment that drives successful outbreak of diseases.

In order to successfully tackle or reduce the incidence of a disease, the triangle has to be broken.

<em>In the case of malaria which is caused by plasmodium but spread through the female anopheles mosquito, one way of breaking the epidemiological triangle is to eliminate female anopheles mosquito in the environment using any possible means. This will stop the spread of the parasite and hence, the disease.</em>

<em>Another way to reduce/prevent malaria is to prevent the vector, female anopheles mosquito from getting to the host, the human populace. This can also be achieved by several possible means.</em>

Relocating the entire village to a neighbouring village might not break the epidemiological triangle as long as female anopheles mosquito still abounds. In the same vein, antibacterial drugs will not help to treat malaria. However, instructing residents on personal protective measures and controlling the vector through chemical larvicides will go a long way in breaking the triangle and reducing the incidence on the malaria disease.

<em>The correct options is B and C.</em>

Many proteins are made and excreted from the cell. Using the list, put the cellular events in order. a. Vesicles containing prot
Irina-Kira [14]

Answer:

c. Proteins and lipids are made on the ER membrane and put in vesicles.

a. Vesicles containing proteins and lipids fuse with the Golgi bodies.

d. The Golgi bodies tag the molecules to signal their ultimate delivery.

b. Vesicles pinched off from the cristernae carry the molecule to its location.

Explanation:

Proteins are made by the ribosome machinery of the rough endoplasmic reticulum. The proteins made need to be packaged before they are sent outside the cell to their location. If the proteins are not packaged and tagged, then they will be degraded by different enzymes present in the cell. So, the packaging of the proteins is done by the Golgi-complex. After packaging is done and tags are added to the proteins, the proteins move to the outside of the cell in vesicles.
