What explains how the parents in a family both have the same eye color, but some of their children have a different eye color? Assume for this example that eye color is determined by a single gene.
A. One parent is homozygous dominant, and the other heterozygous for a gene that controls eye color allowing some of the children to express a different trait.
B. The parents are both homozygous dominant for a gene that controls eye color allowing some of the children to get two recessive alleles.
C.One parent is homozygous dominant, and the other homozygous recessive for a gene that controls eye color allowing some of the children to express a different trait.
D. The parents are both heterozygous for a gene that controls eye color allowing some of the children to get two recessive alleles.
The correct option is D. The parents are both heter0zyg0us for a gene that controls eye color allowing some of the children to get two recessive alleles.
What is complete dominance?When the dominant allele completely masks the recessive allele, we talk about complete dominance.
This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant trait. The dominant allele is hiding the expression of the recessive allele.
In the exposed example, let us assume that the alleles that code for eye color are the followings,
E is the dominant allele and codes for the dominant colore is the recessive allele and codes for the recessive colorIf at least one parent is h0m0zyg0us dominant for the trait, EE, the whole progeny will express the dominant trait because all of them will carry at least one dominant allele.
If both parents are heter0zyg0us Ee, some children will express the dominant trait and some other the recessive trait. This is because some of the children receive at least one dominant allele and some others only receive recessive alleles.
Cross:
Parentals) Ee x Ee
Gametes) E e E e
Punnett square) E e
E EE Ee
e Ee ee
F1) Genotype
1/4 = 25% of the progeny is expected to be h0m0zyg0us dominant EE
1/2 = 50% of the progeny is expected to be heter0zyg0us Ee
1/4 = 25% of the progeny is expected to be h0m0zyg0us recessive ee
Phenotype
3/4 = 25% of the progeny is expected to have the dominant eye color
1/4 = 25% of the progeny is expected to have the recessive eye color
The correct option is D. The parents are both heterozygous for a gene that controls eye color allowing some of the children to get two recessive alleles.

The methods for positively identifying a species and its life cycle stage have not fundamentally changed in the past 200 years. True False
Answer:
False
Explanation:
You’ve found some fossil bones while digging in your backyard. could they be dinosaur bones? using carbon dating, you determine that 3% of the original radioactive carbon-14 is still radioactive. (the rest has decayed into nitrogen-14.) how many half-life cycles has it gone through? approximately half-life cycles.
Since 3% of the original radioactive carbon-14 is still radioactive, the carbon-14 radioisotope has undergone five half-lives.
What is Half-Life?Half-life of a substance is the time it takes for half the original amount of the substance to decay.
Radioactive elements decay spontaneously according to their half-lives.
Since 3% of the original radioactive carbon-14 is still radioactive, the number of half-lives undergone is determined as follows:
After one Half-Life, 50% remains
After two half-lives, 25% remains
After three half-lives, 12.5% remains
After four half-lives, 6. 25% remains
After five half-lives, 3.125 % remains.
Therefore, the carbon-14 radioisotope has undergone five half-lives.

Which brain structure relays incoming sensory information.
The thalamus is an egg-shaped structure in the middle of your brain that acts as a relay station of all incoming motor (movement) and sensory information — hearing, taste, sight and touch (but not smell) — from your body to your brain
The thalamus in your brain functions as a relay point for information. Your thalamus is required to digest all of the information coming in from your senses (with the exception of your sense of smell) before it can be transmitted to the cerebral cortex of your brain for interpretation.
In addition, the thalamus contributes to the processes of sleeping, waking, being conscious, learning, and remembering.
