Explanation:
Genetic variation in offspring during sexual reproduction is caused by
- crossing over
- independent assortment
- randomized fertilization
Further Explanation:
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.
Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell.
- crossing over: the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined.
- independent assortment in metaphase I of meiosis: chromosomes align independently and genes segregate independently into new combinations ...in humans 2n, n = 23, 8 million combinations of chromosomes possible
- randomized fertilization: sperm cells fertilize an ovum to form a zygote. This occurs randomly by chance, to result in a complete set of chromosomes 2n, that is a novel combination of half each parent's number of chromosomes

I like forest animals mostly and i would wanna be a wolf because they have few predators
Answer:
The metabolic capacities should be:
Bacteria that fulfill replicative cycles, have a metabolization that requires a substrate or a metabolite, coexist in extreme environments where their method of survival is sporulation.
Ability to admit genetic mutations between different bacterial colonies for their possible evolution, an ideal environment with pH, gases, and substrates according to the life of the bacterial colony, which is often called as a culture medium.
Explanation:
Temperature is essential in bacterial growth, as is the pressure and environment that surrounds the bacteria.
Something that must be taken into account is that other microorganisms coexist with the bacteria in the medium, since they can be limited to their colonization, an example of this is the gram negative and positive bacteria, coccoid and bacilloid, which generally are not compatible with the penicillium fungus, as this, as a product of its metabolization, releases a substance called penicillin that prevents the colonizing growth of other species of microorganisms such as this type of bacteria.
<u>Answer:</u>
is an inorganic compound.
<u>Solution:</u>
- Firstly, all the known definitions of organic compounds excludes Carbonic acid and it's salt from organic compounds except if 'C' is present in the cation.
- Secondly, Sodium is a metal which organic compounds cannot posses as a compound.
- Lastly, there is absence of C-H bond which is present in all the organic compounds.
Hence, we can conclude that is an inorganic compound though there is presence of Carbon atom in it.
