Internal fertilization-
In this type of fertilization, the fusion of the male and female gametes takes place inside the female's body, as in case of birds, mammals and reptiles.

External fertilization-
In this type of fertilization, the fusion of the male and female gametes takes place outside the body of the female, as in case of fish,frogs and star fish.

How does the structure of an amino acid replicate to its function in cellular processes? Use the role of amino acids in the stru
Alona [7]

A protein's shape directly affects how well it works. For instance, a protein works as a protective protein or a structural protein if its structure is fibrous, as is the case with proteins like collagen and keratin. The protein becomes denatured and ceases to serve its intended purpose if the structure of the amino acids is altered in any way.

<h3>What are amino acids?</h3>

Organic substances known as amino acids have both functional groups for amino and carboxylic acids. Alpha-amino acids, which make up proteins, are by far the most significant amino acids in nature, despite the fact that there are hundreds of other types. The genetic coding only contains 22 alpha amino acids. An organic compound is an amino acid. Carbon-hydrogen bonds are present in organic compounds. All amino acids share a similar fundamental structure. Each molecule has a core carbon atom that is joined to a hydrogen atom, a basic amino group, a carboxylic acid group, and an R-group, also known as a side-chain group.

If a cell loses control of gene expression, what happens?
kipiarov [429]

Answer:

Abnormal, unhealthy cells develop

Explanation:

Gene expression is the process through which genes are turned on through transcription, and to some extent through the translation of the mRNA.

Gene expression is highly regulated to ensure the cell can create the correct combination of proteins to carry out it's tasks. If gene expression is out of control, the mRNAs that are transcribed in the cell are not properly regulated, and therefore the proteins in the cell are not regulated. Since proteins carry out essentially every function in the cell, the cell becomes unhealthy, and incorrectly uses its resources.

Accurate control of gene expression also ensures that the cell can perform specialized functions, it is what makes a heart cell distinct from a brain cell, for example. Therefore, if it is out of control, cells will not be specialized correctly.

ser-zykov [4K]

Answer:

In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa.
