This area of study is called biogeography.

Biogeography is the study of the geographical distribution of fossils, various species (plants and animals) and ecosystems throughout geological time and space. Biogeography is also concerned with the factors that are responsible for differences in distribution of species. The three main fields of biogeography are; historical biogeography (involves species distributions from an evolutionary perspective), ecological biogeography (deals with factors that contributes to species distributions) and conservation biogeography.

To efficiently provide the ideal amount of nitrogen fertilizer, some farmers make use of a "chlorophyll meter" that measures the
NikAS [45]

Answer:

Chlorophyll is a green pigment found in chloroplast in plants. It absorbs sunlight during the process of photosynthesis. It is a chelate molecule. In a chelate molecule a central metal ion forms bonds with a large organic molecule made of carbon, hydrogen and other elements like nitrogen or oxygen.

In chlorophyll, magnesium is the central metal ion and it is bonded to a large organic molecule called as porphyrin. Porphyrin constitutes four nitrogen atoms to which the central magnesium is bonded in square planar arrangement. Since chlorophyll is responsible for the green color of the leaves, more the green color more the chlorophyll content and more is the nitrogen content. Hence, chlorophyll meter measures this green light and finds out if the plant needs more or less nitrogen.

Which of the following are true of trans-fatty acids?
pogonyaev

The following given statements are true of trans-fatty acids:

A. Often created by treating plant oils with hydrogen

D. Occur naturally in in food

<u>Explanation:</u>

The unsaturated fatty acids that are produced by a method called hydrogenation through the addition of a hydrogen molecule to vegetable oils is understood as "Trans-fatty acids". According to the hydrogenation process the composition of the fatty acids varies. The unsaturated fatty acids trans structure receives one double conjugated bond and obtains a straight shape and rectifies the twisted shape created by cis bonds.

Increasing the concentrations of trans-fatty acids particularly in the red blood cell membranes can lead to blockage of the blood vessel as a whole and enhance the risk of heart disease. Meat and dairy products kind natural food materials include trans fatty acids.

Transcription of DNA in eukaryotes is different from transcription in prokaryotes. In eukaryotes a gene that is transcribed make
vekshin1

Answer: Exons

Explanation:

In eukaryotic cell the primary transcript are very long the contains coding region (exons) and non coding region (introns)

The parts of the gene sequence that are expressed (coding region) in the protein are called exons, because they are expressed, while the parts of the gene sequence that are not expressed in the protein are called introns, because they come in between the exons.

Intron is a portion of a gene that does not code for amino acids. These Intron sequence are cleaved out and exons are spliced (I. E combine together) to form the mature mRNA molecule.

Exons are the mRNA parts that are kept and used to make protein.
