Answer:
Average atomic mass = 21.38 amu.
Explanation:
Given data:
Mass of first isotope = 21 amu
Abundance of first isotope = 62%
Mass of second isotope = 22 amu
Abundance of second isotope = 38%
Average atomic mass = ?
Solution:
Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) / 100
Average atomic mass = (62×21)+(38×22) /100
Average atomic mass = 1302 +836 / 100
Average atomic mass = 2138 / 100
Average atomic mass = 21.38 amu.

Because the DNA is being recombined with other DNA.
A genotype is what makes the phenotype
and yes their offspring could have straight hair if the genotype is dominant or heterozygous
Findings show that short-term changes in inhibitory control are predictive of alcohol consumption, which raises the possibility that temporary changes in inhibition may be a risk factor for periods of severe drinking.
<h3>What is inhibitory control?</h3>
- An essential part of impulsivity and executive functioning, inhibitive control refers to the capacity to halt, alter, or postpone incorrect behavior.
- It is also a crucial part of the larger concept of self-control. Utilizing computerized challenges like the stop signal task, inhibitory control can be operationalized in the lab. In order to complete this task, participants must react quickly to arbitrary on-screen "go" cues.
- The participants are instructed to suppress their reaction on a small percentage of trials where a visual or aural "stop" signal is provided shortly after the go stimulus. Participants' actions during stop trials can be described as a "race" between their motor reaction and their ability to regulate that response.

Explanation:
1. Human and apes are evolutionarily closely related based on the analysis of their DNA sequences.
2. Wings of bats and birds serve the same function and are analogous structure.
3. Comparative anatomy is the study of the similarities and differences in structures in similar species.
4. Fossils demonstrate that during the evolution of the whale, the whale moved from land to the sea.
5. The human tailbone and appendix are vestigial organs.
6. The homologous structures are structures that are similar in related organisms because they were inherited from the common ancestor.
7. Comparative embryology is the study of similarities and differences in the embryo of different species.
8. The forelimb of all the mammals has basic bone structure.
9. Scientists who find and study fossils are called paleontologists.
