Answer:
Im not sure how to circle but the three components should be circled...
Explanation:
There are 8 nucleotides in this picture.
A nucleotide consists of a phosphate group (the blue circle), a pentose sugar (the blue pentagon), and a nitrogenous base (the red, green, purple, and yellow hexagons). One nucleotide would only have one of the nitrogenous bases.
Answer:
The parent with the genotype Aa BB Cc dd can produce 4 different types of gametes.
Explanation:
<em>The law of independent assortment states that the alleles for a trait separate when gametes are formed. </em>
In the parent genotype Aa BB Cc dd, the allelic pairs with variation present are Aa and Cc. Therefore, the source of variation in the possible combinations during meiosis, largely arises from these 2 allelic pairs.
Independently assorting these pairs, we have ; A, a, B, B, C, c, d, d
The possible combinations therefore are:
That's correct - it's a square where on one axis, the paternal allele (allele = one of the possible forms of the same gene), and on another the maternal allele is listed. Often, it's also indicated whether an allele is recessive or dominant.
Then, in the table that results, all the possible "combinations" of allele between the paternal and maternal party are created. If you count how often a certain combination appears, it indicates the likelihood of that combination.
See the picture (though it is directly from Wikipedia, please note). The likelihood of BB is 25%, of Bb is 50%, and of bb 25%.
Really really really small
Answer:
excretory system
Explanation:
The excretory system is the system of an organism's body that performs the function of excretion, the bodily process of discharging wastes. ... There are several parts of the body that are involved in this process, such as sweat glands, the liver, the lungs and the kidney system. Every human has two kidneys.
