Yes, it does, but not the way people think. it doesn't gain it from the weight of all the people. the earth takes mass from elsewhere, as our population continues to grow.
If crossing over occurs only between two chromatids, these crossover chromosomes produce the recombinant gametes and the remaining two are similar to the parentals.

Explanation:
cadherins are molecules that allow cell adhesions. various number of cell bind together using this molecules for
proper functioning.
Answer:
C Halobacterium species
Explanation:
ThIs is because this species of bacteria thrive well in high salt concentrations; and will be inactive in a low salt concentration medium.They are known as Hallophilic Organisms. (salt organism)s
They are rod-shaped, motile organisms , which reproduced by binary fission,live in saline lakes, with the cell bounded by a single layer of plasma membranes.They contain beta-caroteen pigments. it is this that is responsible for their red coloration.When this pigment is extracted, is used in food dye. giving food red coloration.
In addition, Halo. Bacteria contain some enzymes that can break dowm organic molecules to simplest forms. These are Degredative enzymes.(e.g Lipase , Amylases). it is this feature that aids their application for aiding the process of fermentatio<u>n of salty foods</u>, and also aiding of <u>coffee processing during production. </u>
<u>Since this is called a salty bacterium, and its enzymes will be most active in high salty concentrations, then option C is the correct answer.</u>
