Correct answer: True
The coral reefs are made up of thousands of tiny animals called as polyps. These are related to anemones and jellyfish. It possesses a sac-like a body and an opening which is encircled by the stinging tentacles called as cnidae.
They use calcium and carbonate ions which are derived from the seawater to in order to make a hard, cup-shaped skeleton. It protects the soft and delicate body of the polyp.
Hence, the correct answer would be true
We first check the first parent's possible alleles: OT, Ot, OT, Ot. (Combinations of the 2 O-alleles and T-alleles given).
A similar process is used for the second: OT, Ot, oT, ot
Genotypes: Check the attachment. We combine the alleles from each parent (for example, Ot + oT = OoTt). We do this for all 16 combinations.
Genotype Likelihoods: We count each of the possible results and tabulate the number of times each appears, and divide by the total number of combinations (16).
OOTT: 2/16 = 1/8 = 0.125
OOTt: 4/16 = 1/4 = 0.25
Oott: 2/16 = 1/8 = 0.125
OoTT: 2/16 = 1/8 = 0.125
OoTt: 4/16 = 1/4 = 0.25
Oott: 2/16 = 1/8 = 0.125
Phenotypes: Check attachment. Based on the genotypes, use the dominant gene if at least one is dominant (Ex. Oo = O, oo = o)
Phenotype Likelihoods: We count the number of each possibility, only 2 of which are present: OT and Ot, then divide by the total number of combinations, which is 16.
OT: 12/16 = 3/4 = 0.75
Ot: 4/16 = 1/4 = 0.25
Answer:
All plants need these seven things to grow: room to grow, the right temperature, light, water, air, nutrients, and time.
Explanation:
Answer:
Sexual Reproduction. ... Organisms that reproduce sexually by joining gametes, a process known as fertilization, must have a mechanism to produce haploid gametes. This mechanism is meiosis, a type of cell division that halves the number of chromosomes. Meiosis occurs only in gamete producing cells within the gonads.
Explanation:
Chromosomes are turned on or off. Ex. genes for karatin (which makes hair) are turned on when they are on top of your head, but are turned off on the palms of your hands.
