It produces air which is essential and the main reason plants and such are needed
Answer:
a) The allele frequencies are - 
b) Genotype frequencies for this population- 
Explanation:
Given ,
Red color of flower is dominant to white color flower
Let "R" represents allele for red color and "r" represents allele for white color
out of 
flower, 
are red flowers.
So the frequency of red flowers with genotype "RR" is equal to
As per hardy Weinberg's I equilibrium equation -
a) The allele frequencies are -
Frequency of genotype "rr" i.e homozygous recessive white flower is
Substituting the values of 
and 
, in below equation, we get -
b) Genotype frequencies for this population-
Answer:
180seconds
Explanation:
From the question, Kepler-186f is an exoplanet that orbits a star called kepler-186, other than the Sun.
Distance of the star (kepler-186) away from the planet is 5.4 x 10^10 meters
To calculate how long i.e. time, a light moving at an average speed of 3.0 x 10^8 m/s will get to the exoplanet from the star, we use the following formula;
Speed (m/s) = Distance (m) ÷ time (s)
Time = Distance/speed
Time = 5.4 x 10^10 ÷ 3.0 x 10^8
Time = 5.4/3.0 × 10^ (10-8)
Time = 1.8 × 10^2
Time = 180seconds.
Answer:
THE FOLLOWING ARE TRUE;
1. CONJUGATION IS A TYPE OF REPRODUCTION
2. CONJUGATION INCREASES THE GENETIC DIVERSITY OF BACTERIA
3. FISSION CAN OCCUR AS OFTEN AS ONCE EVERY HOUR UNDER IDEAL CONDITIONS
Explanation:
Conjugation is a form of reproduction in bacterial cells in which cells transfer DNA by direct contact with the recipient cell. The process is mediated by plasmids which are non-chromosomal DNA molecules. Conjugation occurs in one direction because the donor cell is the only one with the conjugate plasmids. The donor cell sends out its sex pilus and attaches it to the recipient cell creating a conjugal bridge from which genetic materials can be transferred between the two cells. The bacterial chromosomes can also be transferred through conjugation. Conjugation allows for genetic diversity in bacterial cells because the transfer is unilateral and non-identical daughter cells are produced.
Fission of bacterial cells involves the splitting of the bacterial DNA that is replication, then the bacterial cell elongates and later split into two daughter cells with identical DNA. Fission in bacteria can take place every twenty minutes or often every hour under ideal and optimum conditions and a bacteria can produce a generation in just few hours.
During fission a conjugation tube is not formed, conjugation tube is formed during conjugation type of reproduction of bacterial cells and also conjugation does not produce genetically identical daughter cells because wide varieties of DNA or genes can be transferred resulting in bacteria with traits of several different species.
A. The chick of another loon living near Crystal Lake
Reason: B is incorrect because it is not in the same lake
C. Is incorrect because a bluegill is not the same species, therefore it does not contribute to the loon population
D. Is incorrect because that was 40 years ago, and is not current. That loon no longer contributes to the loon population.
