Hoochie [10]3 years ago
8 0

Answer:

B

Explanation:

This macromolecule is DNA. Its stored genetic information in form of genes that translate to functional or structural proteins that make up an organism.  The DNA double helix is unzipped by helicases enzymes into single strands. RNA polymerase transcribes the single strands into mRNA. The mRNA is then translated into proteins by ribosomes. This is called the central dogma (DNA  RNA  Proteins).

During cell division, the DNA is replicated into two copies and each copy goes to each of the two daughter cells preserving, more or less, the same genetic code to the new cells.

Suppose an animal is heterozygous AaBb, and the traits are not linked. When meiosis occurs, what is the total number of possible
GrogVix [38]

Answer:

4 possible combinations of gametes

Explanation:

The animal is considered an heterozygotic dihybrid because it involves two genes that have different alleles for both genes. The dihybrid animal undergoes meiosis to produce gametes. According to Mendel in his laws of segregation and independent assortment, the alleles of the two genes separate into gametes independently of one another to produce 4 types of gametes.

Number of possible combinations of gametes formed by an heterozygote can be determined by using 2^n, where n is the number of characters. Number of characters or genes involved in this case is 2, Hence, 2^2 = 4 gametes.

The allelic combination in the four gametes are: AB, Ab, aB, ab.

The same agricultural practices are used in every country of the world.
makkiz [27]

Answer:

Well you already know the answer is false but I want to elaborate on this for other people who have the same / similar question.

The main source of meat, milk and eggs in most, if not all, countries are Factory-Farms, which are highly abusive, cruel industries that provide meat to around 99% of business I assume haha. A lot of businesses that claim to use "humane" practices of getting meat, dairy and eggs are not true, there is really no human way to get meat or dairy (you can humanely get eggs though factory farms don't) you can read more about this stuff on SentientMedia (graphic content warning)

Farms around the world though use different ways of harvesting (by hand, by machine etc.) planting, different kinds of crops, different ways of waters, what kind of land they plant their crops in.

Hope this helps

have a nice day((:
