Answer:

<u>A. red blood cells containing malaria</u>

Explanation:

Malaria is a disease-causing pathogen in humans. It is caused by species of the parasite <em>Plasmodium sp.</em><em>,</em> which is transmitted as sporozoites by the Anopheles mosquito upon biting the host. These travel through the bloodstream to the liver where they mature into merozoites. These reenter the bloodstream and mature into trophozoites and schizonts that produce more merozoites.

When they multiply within the red blood cell, they <u>burst the red blood cell open</u>, and go on to infect other cells. This infection's symptoms are cyclic and include high fever, chills and other flu-like symptoms.

Malaria is a deadly illness, causing harm to its hosts, and in many cases death. <u>Thus, this cannot be defined as symbiosis, which is typically beneficial to both organisms.</u>

Plants make their own food and are called producers. What do plants need to make their own food? A) soil, air and water B) soil,
djyliett [7]

Answer:

D) energy from the sun, air, and water

Explanation:

Plants are producers because they undergo photosynthesis. Photosynthesis is the process of taking sunlight, CO2, and water to produce ATP in the form of glucose and oxygen.

For plants to make their own food they require the reactants of photosynthesis. The reactants are sunlight+6CO_2 + 6H_2O. In other words, sunlight, carbon dioxide (air), and water. Without these reactants, photosynthesis cannot occur.

Things such as soil and fertilizer are helpful to a plant's growth; however, they are not required in the process that creates food for plants.

In patients infected with nonresistant strains of the tuberculosis bacterium, antibiotics can relieve symptoms in a few weeks. H
Natali [406]

Answer:

Infectious dose refers to the minimum number or amount of pathogens required in order to produce a disease or its symptoms. In the given case, the bacterium is non-resistant and is treated with antibiotics.

The antibiotics help in neutralizing the infectious agents; however, full course should be done to eliminate the infectious agent completely out of the body.

If the course is left in between then, there are very high chances that some bacteria may survive. They might not produce disease or symptoms as they would be less than infectious dose.

However, with time, the survived bacteria gain more and more mutations during replication which can develop antibiotic resistance capability in them.

In addition, it is also possible that the survived bacteria can get R-plasmid (which has antibiotic resistant gene) from body's normal flora or from any other infectious agent present in the body by the process of transformation or conjugation.

The R-plasmid enables them to survive even in the presence of antibiotics due to which the treatment of the disease might become difficult.

When under excessive passive tension, what muscle limits scapular upward rotation, posterior tilting, and external rotation?
LiRa [457]

Pectoralis minor is the muscle which limits scapular upward rotation, posterior tilting, and external rotation when under excessive passive tension.

<h3>What is Pectoralis minor?</h3>

This muscle is found below Pectoralis major and originates from the middle ribs to the scapula.

When under pressure this muscle limits the various types of movements which are mentioned above.

Which statement best describes the relationship of photosynthesis and energy?
atroni [7]

Answer:

The correct answer is The process of photosynthesis is energy storing reaction because the process converts light energy into chemical energy which is stored in the bonds of glucose.

Explanation:

Photosynthesis is an important pathway occur in the mesophyll tissue of leaves of plants . Photosynthesis helps in formation of glucose molecule that is stored as polysaccharide starch inside the plant"s body.

       During photosynthesis light energy is captured from sun by the antenna complex of photosystem then the light energy is transferred to the reaction center for its conversion into chemical energy in form of ATP molrcules.

     The so formed ATP molecules helps in the biosynthesis of glucose by various enzyme catalyzed reactions.
