Hunter-Best [27]3 years ago

Each part of the heart is responsible for a certian aspect of how you live-- your blood (pumped through your heart) oxygenates your blood, and ensures that has the nutrients you need to survive. It also carries away waste.  Without each of these intricate pieces, you wouldn't be able to survive.

Marianne is conducting an experiment on homeostasis in paramecium, which is a type of single-felled organism. Which of these obs
Drupady [299]

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.

What is the endosymbiotic hypothesis?
stepan [7]

Answer: What does the endosymbiont hypothesis propose? It proposes that early eukaryotic cells acquired the precursors of mitochondria and chloroplasts by engulfing certain types of bacteria. ... Mitochondria, chloroplasts, and centrioles in eukaryotic cells each contain their own minute and unique supply of DNA.

Explanation:

The first piece of evidence that needed to be found to support the endosymbiotic hypothesis was whether or not mitochondria and chloroplasts have their own DNA and if this DNA is similar to bacterial DNA. This was later proven to be true for DNA, RNA, ribosomes, chlorophyll (for chloroplasts), and protein synthesis.
