Answer:
Gene Linkage
Explanation:
In a situation where we have two genes which are for two different traits or different characteristics situated on the same chromosome they will said to be LINKED GENE and will often have the same Gene inheritance which is what is called GENE LINKAGE reason been that the genes are on one chromosome and Secondly they are situated very close to one another which is why they will mostly be inherited together. Example a person may have a brown eyes and a brown hair because the genes for the hair and eyes are situated close to one another which is why the genes are both inherited together.

name two substances that will be attacked by a corrosive acid
The name of two substances that would be attacked by a corrosive acid are metals like magnesium, aluminum, zinc, etc, and cloth fibers.
What do you mean by Corrosive acid?Corrosive acid may be defined as a type of acid that is capable of damaging or destroying other substances on contact via a chemical reaction. The chemical reaction which occurred by this contact is extremely fast.
For example, corrosive acid like hydrochloric acid significantly reacts with metals in order to give hydrogen gas and form metal salt. The same principle is applied in the case of cloth fiber and paper. Such corrosive acids rapidly react with them and will damage or destroy them immediately through chemical reactions.
Therefore, the name of two substances that would be attacked by a corrosive acid are metals like magnesium, aluminum, zinc, etc, and cloth fibers.

What are three reasons why it is important for cells to stay so small?
Answer:
Cells are so little, so they can maximize their ratio of surface area to volume. Smaller cells have a higher ratio which allow more molecules and ions move across the cell membrane per unit of cytoplasmic volume. Cells are so small because they need to be able to get the nutrients in and the waste out quickly.
Explanation:
i think this is the answer so yeah:D
Answer:Cells are small because they are more efficient as smaller entities. Information within small cells is transmitted more quickly and efficiently than within larger cells. The nucleus or "command center" of the cell initiates cellular activity by converting genetic information into functional molecules, such as proteins. These proteins and other molecules are then directed around the cell to perform specific functions. The larger the cell, the longer these proteins and other cellular processes will take to carry out their functions. This is quite energy expensive and a less than ideal situation; therefore, cells tend to be relatively small.
As cells increase in size, the volume increases by a power of 3, whereas the surface area increases by a power of 2. This expansion results in a lower surface area-to-volume ratio that is less efficient for transmitting information through cells. Information coming into, traveling through or exiting cells must traverse a much greater distance (through the increased volume) to reach its final destination. Thus a higher cell surface area-to-volume ratio, i.e., smaller cell size, is desired for most efficient cellular activity. Additionally, and importantly, the smaller surface area and larger volume of larger cells does not permit enough molecules to pass in or out of the cell. Because information can enter or exit a cell through it's plasma membrane, the greater the surface area-to-volume ratio, the more molecules that can enter or exit per unit of volume. This is also much more efficient for cells.

Explanation:
When a gene mutation occurs, the nucleotides are in the wrong order which means the coded instructions are wrong and faulty proteins are made or control switches are changed.
Answer:
The statement is true.
Explanation:
Mutation can be defined as any permanent alteration in the DNA base sequence of the genome of an organism, that is, a mutation is any change in the nucleotide sequence of the. DNA. This, in turn, can be of two types: By substitution of bases: alterations in the nucleotide sequence of a gene and two classes are known: transitions or transversions, and by loss or insertion of nucleotides: these are modifications where it can be losing or adding a nitrogenous base, which is important for encoding a specific protein and therefore changes the message of the genetic material.

Which part of the cell is selectively permeable? Why does it say so?
Answer:
cellular membranes
Explanation:
Cellular membranes are selectively permeable because they allow only certain molecules to cross into and out of the cell. The phospholipid bilayer is a selectively permeable membrane that surrounds all biological cells. The movement of molecules across the cell membrane bilayer can occur by passive transport (does not require energy) or active transport (requires energy). For example, water molecules pass passively through the cell membrane (passive transport), while other molecules pass through transmembrane proteins against a concentration gradient (active transport).
