8 h2o molecules to 2 h2o molecules
Answers
The conversion of 8 H₂O molecules to 2 H₂O molecules is a chemical change that occurs through a dehydration or condensation reaction. This process involves the removal of water molecules to form a larger molecule and requires energy to occur.
This is a reaction that occurs between two molecules, and results in the formation of a single, larger molecule, while releasing a small molecule, usually water. In this case, the small molecule is water (H₂O), hence the name dehydration or condensation reaction.
During this reaction, the 8 H₂O molecules combine to form 4 H₂O molecules. This reaction is often used in the laboratory to create polymers from monomers. It can also be used to produce certain biomolecules such as carbohydrates, proteins, and nucleic acids, as well as other chemical compounds.
In order to carry out this reaction, energy is required. The reaction occurs in several steps and involves the removal of water molecules from the original 8 H₂O molecules, forming a new, larger molecule. The reaction is reversible, which means that it can be carried out in both directions, depending on the conditions and reactants involved. Thus, the conversion of 8 H₂O molecules to 2 H₂O molecules is a chemical change that can occur through a process known as dehydration or condensation reaction.

how do fruit fly maternal effect genes determine the polarity of the egg and the embryo
Answers
Fruit fly maternal effect genes happen to produce some products which are are deposited into the egg and decide the head and tail and also the back and belly of the embryo and hence they determine the polarity of the egg.
The larva of Drosophila or the fruit fly, like most larval organisms, contains a segmented body in which some clear folds, or segments are visible. Maternal effect genes are able to control early Drosophila development by producing some transcripts or mRNAs which are found in the unfertilized eggs of females.
These maternal effect genes of the fruit fly determine the polarity of the egg as they decide where the back, head, back and belly of the fly will be. Resultantly, they happen to control the orientation of the fly and so they are also called the egg polarity genes.

A rat has 42 chromosomes in eath somatic call. How many chromosomes are in each gamete

what are two use cases for executing anonymous apex code choose 2 answers
Answers
Executing anonymous apex code is a tool that allows users to interactively execute Apex code statements and queries. Given that, there are two use cases for executing anonymous apex code. They are: Use Case 1: Testing Snippets of Code and Use Case 2: Troubleshooting problems with a particular org.
What is anonymous apex code?
Anonymous Apex is a way to test code snippets, practice writing logic, and test governor limits quickly. Anonymous Apex is ideal for making immediate changes to the database for analysis purposes and automating one-time tasks. It is used to quickly test something that you are unsure of, to test a function or class that you've created, and also to verify the results of a particular query.
Use Case 1: Testing Snippets of CodeIt's a best practice to write test code to check that your app works properly, but it can be time-consuming to write test code to test a small part of it. Anonymous Apex is a great tool for quickly testing snippets of code. It's helpful for doing the following: Testing new functionality before incorporating it into a larger codebase. Testing code that was copied and pasted from an external source or developer forum. Testing whether certain code will work in the context of your Salesforce org.
Use Case 2: Troubleshooting problems with a particular org. There are instances when issues in a particular org will arise, and you will have to troubleshoot and find the cause of the problem. This is where anonymous Apex comes in. Because anonymous Apex runs within the context of an org, it can be used to test things like: Creating a record for a particular object Modifying a record for a particular object Deleting a record for a particular object Running a SOQL query Running a DML statement Running SOSL queries Running Apex Code
That's all about two use cases for executing anonymous apex code.

Prokaryotic species, on the other hand, are exceedingly prevalent and account for a large portion of the biomass on Earth.
Unicellular organisms are those that have prokaryotic cells. We refer to them as "prokaryotes." A prokaryotic cell may operate as a live creature thanks to a number of factors. Prokaryotes have a cell membrane covering them at first.
With the help of this membrane, they may engineer a particular environment for metabolic processes within the cytosol. Second, these cells contain both ribosomes and free DNA.
Even though ribosomes are organelles, a plasma membrane does not enclose them.

Depth
Explanation:
The ocean has three layers from the top to bottom containing different temperatures. The first layer is of warm oceanic water approximately 500 m think containing temperatures of about 20 degrees Celsius to 25 degrees Celsius. The second layer is the thermocline layer characterized by a decreasing temperature with increased depth. The last layer is that of very cold temperature that extends to the deep ocean floor. There are other factors which affect the distribution of temperature of ocean water which include: latitudes, unequal distribution of land and water, prevailing wind and ocean currents.

evolution operates at the population level, not the individual level. why?
Answers
Evolution operates at the population level because an individual alone cannot evolve. However individuals in a population vary among themselves and therefore some are more fit than the others. As a result, evolution causes more fit people to survive and form a population of fit individuals.
Evolution is the phenomenon of slow and gradual changes that occur in a population over long durations of time. The process of evolution causes better surviving individuals to carry forward. Evolution causes morphological characters to be enhanced.
Fitness in evolution can be defined as the ability of the individuals to survive in unfavorable environments. The most important trait that defines fitness is the ability to reproduce and give birth to offspring.
