Cell is the structural and functional unit of life. All living organisms are made up of cells. The size of any living cell is limited. Limited cell size has many advantages.
Answer: Analogy to explain why cell size is limited is SMALLER THE SIZE OF A CELL LARGER WILL BE THE SURFACE AREA TO VOLUME RATIO.
Angiosperms are the most diverse
and successful plant group. It has double fertilization which leads to the
formation of an endosperm. It also has a stamen with two pollen sacs. It has a
phloem tissue that is composed of sieve tubes and companion cells.
Answer:
See the answer below.
Explanation:
<em>Let the allele for eye color be represented by A. Blue is dominant over brown eye color, hence, blue allele would be A while brown eye allele would be a.</em>
Two parents have the genotype blue/brown which is equivalent to Aa.
Aa x Aa
AA 2Aa aa
blue eyes blue eyes brown eyes
a. Different possible outcomes: AA blue eyes, Aa blue eyes, and aa brown eyes.
b. Probability of a child from the cross having brown/brown (aa) genotype = 1/4 or 25%
c. Probability that the child would have blue eye color = 3/4 or 75%
Answer:
The correct answer will be- 21, 29, 29
Explanation:
In a DNA sequence, the nucleotide base pairs on one strand of DNA are complementary to the base pair on other strand of DNA.
According to the Chargaff rule, Adenine binds Thymine and Cytosine binds Guanosine which shows that the amount of A will equal T and the amount of G will equal C.
Therefore, when the amount of C is 21%, then the amount of G will be 21%.
To find amount of AT= 100-GC
AT= 100-42
AT= 58%
So, AT/2= 29% each
Thus, A=T= 29%
G=C=21%
There are 5 levels of cell organization recognized by biologists.
