Answer:
B. 62, because this number will create a haploid cell, allowing both female and male gametes to be combined.
Explanation:
Sexual reproduction involves two organisms to come together (male and female). Sexually-reproducing organisms make use of a process called MEIOSIS to produce gametes or sex cells, which have a reduced number of chromosomes as the parent cells producing them.
A sexually reproducing organism must contain a complete diploid chromosome number (2n) that allows it to produce cells with a haploid chromosome number via meiosis. The haploid gamete cells that result from each meiotic divisions of male and female parents can combine to form a whole diploid organism.
Brain loses 5 to 10% of its weight between the
ages of 20 and 90. One study found that the volume of the brain was 15% less in
older adults than in younger adults. On average, the brain loses 5% to 10% of
its weight between the ages of 20 and 90 years; brain volume also decreases.
Answer:
Species distribution is the manner in which a biological taxon is spatially arranged. ... Species distribution is not to be confused with dispersal, which is the movement of individuals away from their region of origin or from a population center of high density.
Since Jordan needs to use the high power objective in order to view the specimen under the light microscope. He should use the ocular lens in order to view the high power objective which is placed in the objective lenses. So he needs to use the ocular lens for viewing and the objective lens to magnify and see the specimen clearly on the stage.
In photosynthesis, carbon dioxide is reduced and H₂O is oxidized. The type of chemical reaction is an oxidation-reduction reaction.
<h3 />
Explanation
Oxidation-reduction reaction are reactions that take place in electrochemical processes. Reduction is the reaction of decreasing oxidation number and increasing electrons and it can be said that reduction is the reaction of a substance losing oxygen. Oxidation is the reaction of increasing the oxidation number and decreasing electrons and can be said that oxidation is a reaction where the reaction of a substance binds oxygen.
Photosynthesis is one type of oxidation-reduction reaction that occurs naturally in everyday life. Photosynthesis has a complex process and involves green plants and certain bacteria. In the event of photosynthesis, carbon dioxide is reduced to carbohydrates and water is oxidized to oxygen.
The oxidation-reduction reaction in photosynthesis is:
6CO₂(g) + 6H₂O(l) + energy --> C₆H₁₂O₆(aq) + 6O₂(g)
