Answers
Answer:
3:1, 2.95:1, 2.82:1, 2.95:1, 3.14:1 AND 1.84:1.
Explanation:
The ratio between yellow and green seed colour is 3: 1. The higher ratio of yellow colour occur because the yellow colour is dominant as compared to green seed colour.
The ratio between round and wrinkled seed shape is 2.95 : 1.
The ratio between green and yellow pod colour is 2.82 : 1.
The ratio between smooth and bumpy pod shape is 2.95 :1.
The ratio between along stem and at the tip of flower position is 3.14 : 1.
The ratio between tall and short plant height is 2.84 : 1.

Which of the following describes the result of independent
assortment and crossing over during meiosis?
A: it creates genetic differences in sperm and egg
B: it produces higher quantities of sperm and egg
C: it produces individuals that are very similar to their parents
D: it makes fertilization go smoothly
Answers
Answer:
A.)
Explanation:
Independent assortment and crossing over is important because it creates genetic variation between gametes. This immediately eliminates (C) and in no way does crossing over or independent assortment cause more gametes to be produced so cross out (B). Only (A) and (D) is left, while both answers makes sense, (A) is the better one.
Meiosis takes place in the germ cells and give rise to haploid gametes. Due to the events including crossing over and independent assortment, it causes genetic differences in sperm and egg, i.e., option A.
What is crossing over?Chromosomal crossover also referred as crossing over, represents the exchange of genetic material during gamete formation,
It occurs between two non-sister chromatids of homologous chromosomes that results in recombinant chromosomes.
This creates genetic differences in the sperms and eggs.
Thus, the correct option is A.

Variations between organisms are caused by differences in
Answers
Answer:
Genetic variation occurs because beneficial traits exist in a collection of genes, and gene flow makes these traits more prevalent in populations.
Further explanation
Genetic diversity is a level of biodiversity that refers to the total amount of genetic variation in the whole species that inhabits some or all of the earth's surface that can be inhabited.
Genetic diversity uses several simple measurements:
Gene diversity is the proportion of polymorphic loci throughout the genome.
Heterozygosity is the average number of individuals with polymorphic loci.
Alleles per locus, also used to demonstrate variability.

Look at the graph...What is the optimal temperature for this enzyme?
A. 60 degrees C
B. 45 degrees C
C. 15 degrees C
D. 35 degrees C
Answers
Answer:
B: 45 degrees C
Explanation:
However, above 40-45 degrees Celsius, enzymes are usually denatured and can no longer catalyse the reaction, because the hydrogen bonds are broken, so the enzyme permanently loses its shape. The temperature at which the reaction rate is fastest is the optimum temperature.
As per the graph, the optimum temperature for the enzyme is 45 degree Celsius. The correct option is C.
What is optimum temperature?The temperature at which the enzyme exhibits the greatest activity is referred to as the optimum temperature.
Enzyme activity decreases as the temperature rises or falls. It can even become inactive at times. It is equivalent to the body temperature of a warm-blooded animal.
The kinetic energy in the substrate and enzyme molecules is optimal for the maximum number of collisions at the optimal temperature.
At high temperatures, the enzyme's shape changes, and it no longer complements its specific substrate.
It is the temperature at which the enzyme's reaction rate is fastest. It will be the point on the graph where the line reaches a peak at 45 degrees Celsius.
Thus, the correct option is C.
