Explanation:

plss mark brainliest

Answer 2

The cell theory asserts that all cells come from existing cells. Option a si correct.

The cell theory is a fundamental principle of biology. It was first proposed in the 19th century by Theodor Schwann and Matthias Schleiden. The cell theory states that:

All living things are made up of cells.Cells are the basic unit of structure and function of all living things.All cells come from existing cells.

The cell theory has been supported by many scientific observations and experiments. For example, scientists have observed that cells divide to produce new cells. They have also observed that cells from different organisms have similar structures and functions.

The cell theory is a powerful tool for understanding living things. It allows scientists to study the structure and function of cells, and to understand how cells interact with each other. The cell theory has also led to the development of new technologies, such as cell culture and genetic engineering.

The other options are incorrect. Option b is incorrect because not all cells contain a nucleus. Option c is incorrect because the cell theory was not established in 1665 by Robert Hooke. Option d is incorrect because a cell membrane does not separate one cell from another. A cell membrane surrounds each cell, but it does not separate one cell from another.

Answers

Answer:

Water is produced as a result of fermentation reactions.

Explanation:

I took the test and the person above me is correct

Respiration taking place in presence and absence of oxygen has different end products. Aerobic respiration has the end products as carbon dioxide and water, alcohol is the end product of anaerobic respiration.

What is respiration ?

It is the process in which the complex substituents are broken into simpler products in the presence of oxygen and absence of oxygen in  order to produce energy.

In the aerobic respiration processes like glycolysis takes place where the glucose breaks down into 4  molecules of ATP with the consumption of 2 ATP molecules. 1 glyceraldehyde molecule is produced from the glucose that is 2 glyceraldehyde molecules are produced. Total of 4 ATP are produced.

Alcoholic fermentation is the anaerobic respiration that says the anaerobic respiration where the glucose is broken down into alcohol and water. In the anaerobic respiration, excess of alcohol gets broken  down into lactate.

What are some things water will adhere to? and What are some things water will not adhere to?

Answers

Answer:

1. Water has an amazing ability to adhere (stick) to itself and to other substances. Hydrogen bonds form when hydrogen atoms covalently bonded to nitrogen (N), oxygen (O), or fluorine (F) in the form of covalent compounds such as ammonia (NH3), water (H2O) and hydrogen fluoride gas (HF).

2. In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.

What is Cicero's philosophy of government?

Answers

Answer:

Cicero proposed that the ideal government "is formed by an equal balancing and blending" of monarchy, democracy, and aristocracy. In this "mixed state," he argued, royalty, the best men, and the common people all should have a role.

Answer:

Like Polybius, Cicero has suggested three types of government—royalty, aristocracy and democracy. But in each form of government there is the germ of corruption and instability and this leads to the fall of government. Only a mixed form of government is the proper guarantee of stability and corruption-free society.

Explain why an earthworm will die if it dries out based on the type of skeleton annelids have and the absence of a respiratory organ or system in the earthworm.

Answers

We can confirm, based on the type of skeleton and lack of a respiratory organ, that a worm will die if it dries out due to the fact that the exchange of gases happens through the mucus on its skin.

As stated in the question, Earthworms do not possess any form of respiratory organs. To account for this, they have evolved the ability to breathe through their skin. This ability is due to what is known as a hydrostatic skeleton, possessed by most annelids.

This skeleton is covered in mucus and allows the exchange of gases with its surroundings, therefore, if the worm were to dry up, the mucus that encases the skeleton would harden and thus prevent the interchanging of oxygen and carbon dioxide. Effectively, the worm would not be able to breathe and would die.
