Which statement is an accurate description of genes? 1
Proteins are made of genes and code for DNA.
2.
Genes are made of proteins that code for nitrogen bases.
3.
DNA is made of carbohydrates that code for genes.
4.
Genes are made of DNA and code for proteins.

An accurate description of genes is that genes are made of DNA and code for proteins.

Explanation:

Genes are the molecules responsible for containing the genetic information that determines specific characteristics or features of an individual. Genes are housed in chromosomes, in specific locations called locus.

A DNA molecule forms a chromosome, and fragments of that same molecule form the genes on that chromosome. The information contained in each gene codes the synthesis of proteins, as well as the synthesis of RNA.

The other options are not correct because:

     1. Proteins are not made of genes, but of amino acids, and they do not code for DNA.

    2. Genes are not made of proteins, but of DNA fragments.

    3. DNA is not made of carbohydrates.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
