Malaria, a type of parasite, infects 500 million people each year by infecting the red blood cells of its host. The virus, HIV, that causes AIDS, reports 50,000 newly infected persons. Which statement best differentiates the pathogens, parasites and viruses?
options: Although both rely on other living organisms to survive, viruses are usually beneficial.

Although both rely on other living organisms to survive, parasites feed on the host organism.

Although both are living organisms, viruses break down dead plants and animals that other organisms use.

Although both are living organisms, parasites depend on the cells of living things to reproduce.

Answers

Answer 1

Answer:

The second statement clearly differentiates the pathogens best. Parasites feed on living host while viruses depend on the cells of other organisms to survive and reproduce as they cannot function outside a living host.

Answer 2

Although both rely on other living organisms to survive, parasites feed on the host organism. The correct option is B.

What are parasites?

A parasite is an organism that lives on or in the host and obtains its food from or at the expense of the host.

Protozoa, helminths, and ectoparasites are the three main types of parasites that can cause disease in humans.

They frequently go unnoticed because they have few symptoms. However, these infections frequently result in serious illnesses such as seizures, blindness, heart failure, and even death.

A parasitic relationship takes place when one lifeform, the parasite, feeds on another organism, the host, causing harm and possibly death.

The parasite lives on or in the host's body. Tapeworms, fleas, as well as barnacles are examples of parasites.

Thus, the correct option is B.

Nonnative species can cause serious problems with marine ecosystem biodiversity. The graph shows a summary of the different methods by which invasive species reach new locations based on United States Geological Survey data as of 2016. Based on this information, what recommendation could be made to reduce introductions?

A- Methods should be put in place to reduce the ability of species from escaping from captivity and establishing themselves in new locations.

B- People should take extra care when setting up a home fish tank to be certain that all organisms in it will be properly maintained so that the animals remain healthy and diseases are not spread.

C- Science should more closely study the genetics of the different organisms used to prevent mixing of DNA.

D- Ships should install some form of cleansing mechanisms before releasing their ballast water during transport and should be checked for unintended cargo.

Answers

Answer: D

Explanation: 20% of invasive species are introduced by Shipping so checking the ballast tanks in cargo ships would help the most I think

To reduce introductions of Non-native species, ships should install some form of cleansing mechanisms before releasing their ballast water during transport and also check for unintended cargo.

What are non-native species?

Non-native species are also called invasive species. They are called so as they are foreign or not indigenous to a particular ecosystem and have been introduced to the said ecosystem by some unnatural methods.

These species show a high capacity for adaptation to their new environment. They quickly multiply and reproduce and therefore increase in population.

This sudden and unnatural increase in their population soon after they are introduced to a new environment will greatly affect the ecosystem of the new environment. The new species will compete with the native organisms of that environment for resources. This may cause the native flora or fauna to become endangered or even extinct.

The accidental introduction of invasive species happens quite often and causes a lot of problems. In a marine ecosystem, it happens a lot due to the ships that travel through a variety of marine regions.

So, ships should install some form of cleansing mechanisms before releasing their ballast water during transport and should be checked for unintended cargo.

Therefore, the correct option is D.

Fernanda is feeling sick and goes to the
doctor. Upon taking a blood sample, the
doctor observes that Fernanda's cells
contain a pathogen that seems to be made
of small cells with no nucleus. What type of
infection does Fernanda have?
bacterial
fungal
none of the above
viral

Answers

Answer:

bacterial

Explanation:

A prokaryotic organism is an organism that does not possess a membrane-bound nucleus that houses its genetic material. Organisms grouped under this domain are bacteria, archaebacteia etc.

According to this question, Fernanda goes for a blood sample because she felt sick. The result of the blood sampling shows that the cells of Fernanda contain a pathogen that seems to be made of small cells with no nucleus. This property describes a prokaryotic pathogen. Hence, the infection is most likely to be that of a BACTERIAL INFECTION.

Note that, a fungus is eukaryotic while a virus is considered non-living because it can only replicate in a living host.

Mosses have some water-conducting cells, but they do not have the empty, lignin-reinforced cells that allow vascular plants to transport water with strong pressure gradients. Thus, mosses have very limited water transport ability and can't grow very tall.

What needs to change so that only the green solutes diffuse across the membrane?

Answers

Diffusion is a process which allows particles to move from areas of high concentration to areas of lower concentration. The process requires that particles are moving. As long as particles are not at a temperature of 0K (absolute zero) they have kinetic energy (energy of movement).

What need to be changed is ; The use of selectively/semi-permeable membrane

To selectively allow the passage ( diffusion ) of a certain type of solute through a membrane in a solution, we should make use of a selectively permeable membrane which allows only the passage of a certain type of solute contained in the solution ( like the green solutes ).

The use of permeable membrane in a solution is to selectively allow flow of solutes or solvent from a region of lower concentration to a region of higher concentration.

Hence we can conclude that what needs to be change is The use of selectively/semi-permeable membrane will allow only the green solutes to diffuse across.

I can't definitively answer this because I don't know the experiment, but I can help.

Explanation:

The "control group" of an experiment is like a dry simulation, where there is no variables changed across all the different trials you do. This is different from a dependent variable or an independent variable. Using your newfound knowledge of what a control group is you can automatically cross off the last option.

Since I cannot see what your experiment was I can't give you which of the top 3 answers it is however. You need to look at which one has no change.

Why is it important to center the object you want to look at in your field of view before changing to a higher magnification objective lens? A. So the object is still in your field of view at the higher magnification. B. So you can always see the entire object at the higher magnification. C. So you do not damage the higher magnification objective lens.​

Answers

Answer:

B. So you can always see the entire object at the higher magnification

Explanation:

A microscope is used to view objects smaller than the naked or unaided eyes can see. The objective lens, in conjunction with the occular or eye lens, is used to achieve this purpose. The objective lens are of different magnifications as follows: 10X, 40X, 100X etc.

However, as the magnification increases i.e. higher objective, the object in the field of view becomes smaller and less focused. Hence, the object in the field of view must first be centered at a lower magnification/objective lens before changing to a higher one in order for the entire object to be seen at a higher magnification.
