Answer:

The correct answer will be option-annelids

Explanation:

Annelids in the phylum of animals which includes about 22000 extant species. The animals of this group possess segmented body and thus are called ringed worms.

Each segment of the body contains the same organs and are usually found in the aquatic environment in the hydrothermal vents and the tidal zones. Some species are found in the terrestrial environment.

Since the biologist found the animal from the deep ocean with a segmented body and soft skin therefore, the animal belongs to the annelids.

Thus, option-annelids is the correct answer.

Rachael wants to test how sunlight impacts plant growth over time. She will add varying amounts of light to different sets of pl
Mrrafil [7]

Answer:

Independent variable: varying amounts of light

Dependent variable: plant growth

Explanation:

The variable, which are factors that can be altered, in an experiment can either be independent or dependent. An independent variable is one in which the experimenter manipulates or controls in order to bring about an outcome. For this experiment conducted by Rachel, the independent variable is the VARYING AMOUNT OF LIGHTS.

The dependent variable is the variable that responds to changes of the independent variable. In other words, the dependent variable is the outcome of manipulating the independent variable. Hence, the dependent variable is dependent on the independent variable. For Rachel's experiment, the PLANT GROWTH is the dependent variable because it is what responds to changes in amount of light (independent variable).

did Anna appear to be following a diet appropriate for a person with type 1 diabetes and why or why not
Sphinxa [80]
While you didn't provide us with a list of foods that Anna is eating or has eaten in the past, her diet would be appropriate for her if she was abstaining from food that has a high glycemic impact (bread, pasta, candy, chocolate) on her body, or just food which contains glucose in general. Both of these are not allowed for diabetics as they might trigger unwanted effects.

What is the difference between immune deficiency and opportunistic infection?
RoseWind [281]

Answer:

Immunodeficiency disorders prevent your body from fighting infections and diseases. This type of disorder makes it easier for you to catch viruses and bacterial infections. Immunodeficiency disorders are either congenital or acquired. A congenital, or primary, disorder is one you were born with.  whereas Opportunistic infections (OIs) are infections that occur more frequently and are more severe in people with weakened immune systems, including people with HIV. Many OIs are considered AIDS-defining conditions.
