Rainwater is very important in my area, we use it for crops, animals and for everyday essentials. It's collected in jars and kept stored, it can be filter then boiled to extract any bacteria. Then I usually sit it outside in the sun to grab the suns energy. This saves me a lot of money on utilities like my water bill for example. It's safe for everyone and poses no threat to the environment.

Answer:
Blue crab is an important resource in my region. It is harvested in Chesapeake Bay. People in my region have been eating blue crabs for hundreds of years. Blue crabs are usually harvested in traps called crab pots. Most crabs are harvested commercially, but recreational crabbing is also important. Crab harvesting in Chesapeake Bay is regulated by the states of Maryland and Virginia, and special licenses are required. Limits are placed on the number of crab pots and the sizes of crabs that can be kept. Even though regulations are in place to protect the crabs, their numbers are declining due to deteriorating water quality in Chesapeake Bay. The crabs require additional protection, but too many restrictions could put people out of work because blue crabs are a popular, traditional food in the region, and thousands of people make a living from crab fishing. The natural resources management of the crabs is inadequate because the crabs continue to be harvested in an unsustainable way.

Why does the moon have craters in it?
Answer:
Because the Earth has an atmosphere, the Moon has more craters than the Earth. While we sweep up a lot more things because of our higher gravity, the majority of it burns up on entrance and never reaches the earth. Earth also possesses liquid water. This is significant in two ways: first, most things that strike water do not create a crater, and second, water erodes previous craters.

If an herbicide were to selectively inhibit development of antheridia in a moss colony, what would be the consequence?
The most likely consequence of a herbicide that selectively inhibits the development of antheridia would be the reproduction of female plants only.
Whta are antheridia?The antheridia are haploid reproductive structures that produce male gametes in some types of plants.
The antheridia can generate a special type of biflagellate sperm (male gametes) required during se_xual reproduction.
Conversely, archegonia is a structure that produces a single egg, i.e., the ovum or female gamete.

Hint: The wall which is present at the outermost of the cell wall acts as a glue between the different cells. . The secondary wall is not present in every cell, it is present in few cells that alter the growth of the primary wall.
Complete answer:
A cell wall is an outer structural layer present in only some types of cells, just outside the cell membrane. It is usually tough, flexible, and sometimes rigid. The cell wall is mostly composed of two layers and sometimes three layers too. The layers of the Cell wall are as follows-
- The primary cell wall is generally a flexible thin, and an extensible layer formed while the cell is growing i.e not fully developed. It is usually made up of cellulose and it is often permeable too.
-The middle lamella, a layer rich in pectins. It is the outermost layer that forms the interface between adjacent plant cells and glues them together.
-The secondary cell wall, if present, is a thick layer formed inside the primary cell wall after the cell is mature. it's not found in all cell types.
Additional Information: The cell wall is majorly composed of the cellulose microfibrils that are linked via hemicellulosic tethers to form the cellulose-hemicellulose network, which is embedded in the pectin matrix. The most common hemicellulose present in the primary cell wall is xyloglucan.
The outer part of the primary cell wall of the plant epidermis is mostly covered with the cutin and wax, forming a permeability barrier known as the plant cuticle.
Secondary cell walls contain a wide range of additional compounds that helps to enhance and modify their mechanical properties and permeability. The major polymers that make up wood (largely secondary cell walls) include cellulose, 35-50% .xylan, 20-35%, a type of hemicellulose, and lignin, 10-25%.
The cell wall which is the farthest from the plasma membrane in plants is the primary cell wall.
What do you mean by Cell wall?A Cell wall may be defined as a specialized form of the extracellular matrix that surrounds every cell of a plant. It is made up of cellulose.
The primary cell wall is the outermost cell wall in the plants, while the secondary cell wall is the innermost cell wall in the plant cell.
The secondary cell wall is located near the plasma membrane, while the primary cell wall is located farthest from the plasma membrane.
Therefore, the cell wall which is the farthest from the plasma membrane in plants is the primary cell wall.

Explanation:
What is one possible result of a mutation within a start codon? A stop codon?
The result of a mutation within a start codon is the non-start of the protein translation, whereas a mutation in the stop codon will long the length of the protein.
What are transcription and translation?Transcription refers to the process by which a fragment of DNA is used as a template to create an RNA molecule, usually a messenger RNA.
Subsequently, this mRNA sequence can be used to create a protein by a process called translation.
The triplets of nucleotides (codons) in the mRNA are read by the ribosomes during translation, thereby a mutation in the start codon would produce a nonfunctional mRNA.
Moreover, a mutation in the stop codon will long the length of the resulting protein sequence.
