Marianne is conducting an experiment on homeostasis in paramecium, which is a type of single-felled organism. Which of these observations provides the strongest evidence of a paramecium maintaining homeostasis

Answers

Answer 1

Hello. You did not present the answer options, which makes it difficult for you to receive a specific answer. However, I will try to help you in the best possible way.

One of the most common evidences that a paramecium is maintaining homeostasis is the pumping of water from the vacuoles present in its body.

The paramecium is a protozoan that lives in aquatic environments, mainly those composed of fresh water. The problem with this environment is that water is able to enter the paramecium organism in large quantities and this can promote the disruption of the organism through lysis of the cell. In this case, homeostasis must act quickly and pump water out of the body, through the cell vacuole.

Homeostasis is a regulatory system of the organism, which must promote the balance of the organism, whenever any external or internal factor tries to harm this balance.

5. Does the insect have long antennae?

b. No……………………………………………………………………………… Order Odonata

6. Does the insect have a small body with large fan –shaped wings?

a. Yes…………………………………………………………………………… Order Lepidoptera

b. No………………………………………………………………………………Order Hymenoptera

Answer:  

ORDER ODONATA

Explanation:

It is simple to read a dichotomous key. You only need to understand the technical terminology and to detailed observe your specimen. The key will lead you to the answer.

1. Does the insect have wings?

a. Yes………………………………………………………………………… go to step 2

b. No…………………………………………………………………………. Order Hemiptera

We only need to answer this question by looking at the image. In our example, yes, the insect has wings. So we need to go to question number two. Note: In the hypothetical case that the insect would not have wings, it would belong to the Hemiptera order.

2. Does the insect have parallel wings? (hint: Parallel wings don’t stick out to the side)

a. Yes……………………………………………………………………………… go to step 3

b. No………………………………………………………………………………. go to step 4

Ok, here it tells you that parallel wings do not stick out to the side. But in our example, wings do stick out, so the answer should be NO. This species does not have parallel wings. As it is a NO, we go to question number 4.

Note: In the hypothetical case that the insect would have parallel wings, we should read number 3.

4. Does the insect have 4 total wings?

a. Yes………………………………………………………………………………… go to step 5

b. No………………………………………………………………………………… Order Diptera

This one is easy. How many wings our specimen has? Four. Then it is a YES, and we go to question number 5. Note: In the hypothetical case that the insect would not have 4 wings, it would belong to the Diptera group.

5. Does the insect have long antennae?

a. Yes………………………………………………………………………………go to step 6

b. No……………………………………………………………………………… Order Odonata

Our insect has very short antennae. They are not long at all. So, the answer is NO, the insect does not have long antennae. This answer leads us directly to the order of our individual. ORDER ODONATA. Note: In the hypothetical case that the insect would have long antennae, we should read question number 6. And so on until we would reach the order.  

ORDER ODONATA:

Dragonflies belong to this group. These insects characterize as having big eyes, and the separation between them depends on the species. They have an elongated abdomen, sometimes even longer than the wings. Their bodies must be robust to support the massive musculature that propels the wings during flight. The wings are long, big, and wide.

Usually, the males are much more colored than the females are.

What do you mean by a Gene?

A gene is a basic unit of heredity and a sequence of nucleotides in DNA that encodes the synthesis of a gene product, either RNA or protein.

An activator is known to increase the transcription of a gene, while a repressor binds to the promoter region and inhibits the transcription process. The molecules of mRNA get associated with the gene HBA, HBB which encodes for hemoglobin in red blood cells. Ribosomes and polymerases are known for DNA binding protein.
