Answer:
1 black : 1 orange
Explanation:
This is a typical monohybrid cross involving a single gene coding for eye color in MendAlien. The allele for black eyes (B) is dominant over the allele for orange eyes (b). In an heterozygous state, Bb i.e. combination of both dominant (B) and recessive (b) alleles, the MendAlien will be phenotypically black.
In a cross between a heterozygous MendAlien (Bb) and an orange-eyed MendAlien (bb), two of the offsprings will have a Bb genotype and be phenotypically black-eyed which the other two will have a bb genotype and be phenotypically orange-eyed. Thus, a phenotypic ratio of 2 Bb : 2 bb will be obtained.
This is also equal to 1:1 i.e. 1 black-eyed : 1 orange-eyed.
Answer:
a. Odds ratio = 1.58
b. Inasmuch the odds ratio is greater than 1, this means that higher odds of melanoma exist in people exposed to indoor tanning, than in those not exposed to indoor tanning
Explanation:
For case study
Let 'a' represent the total population of people with melanomia = 696
Let 'b' represent the total number of people with melanomia exposed to indoor tanning = 1107 – 696 = 411 people
For control study
Let 'c' represent the total population = 1500
Let 'd' represent the total number of people not exposed to indoor tanning = 1500 - (0.428 * 1500)
= 1500 - 723
Total number of people not exposed to indoor tanning = 777 people
a. Odds ratio = (a/b) / (d/c) = (696/411) / (777/723)
= 1.69 / 1.07 = 1.58
b. Inasmuch the odds ratio is greater than 1, this means that higher odds of melanoma exist in people exposed to indoor tanning, than in those not exposed to indoor tanning.
Answer:
Yes, I agree with the given statement.
Explanation:
Plants undergo the process of photosynthesis for the production of their food. In this process, they require the presence of sunlight, carbon dioxide, water, minerals, and chlorophyll. The process of photosynthesis is possible only during the day because sunlight is one of the major components. Carbon dioxide is taken in by the plant through the stomata from the environment. The oxygen is formed as a product of the process and is released in the environment. This process becomes impossible during the night because of the absence of sunlight. The entire process sums up to that the plants give out oxygen during the day and give out carbon dioxide during the night.
Answer:
A or B
Explanation:
To be honest both are accurate.
