Involuntary, meaning things in the body such as your heart is all regulated to act unconsciously while also receiving directives from the brain.
Because gametes (sex cells) are the only cells that pass along genetic information. Somatic cells are the cells that have already differentiated into various organs or tissues. They can't pass on a mutation to offspring because they're not involved in creating it.
The answer is D. They fuse during sexual reproduction
In the van deemter equation, plate height (H) = A + B/u+ Cu.
So, A, B, U, and C affects the plate height. A is the eddy diffusion term, B is the longitudinal or ordinary diffusion term, C is the nonequilibrium or resistance to mass transfer coefficient, and U is the linear velocity.
Explanation:
Protons are positively charged sub-atomic particles that are in the nucleus of an atom and have a relative mass of 1. Neutrons have a neutral charge, meaning they have no charge, and are also in the nucleus of an atom with a relative mass of 1.Electrons are negatively charged particles that orbit the nucleus in electron clouds. They are said to have a relative mass of 0.
For example, a sodium atom is number 11 on the periodic table. The atomic number of sodium tells us the no. of protons contained within its nucleus as well as the number of electrons orbiting. So we can say that sodiun has 11 electrons and 11 protons. To determine the number of neutrons, simply subtract the number of protons from the mass number( found on periodic table)
23-11=12 neutrons
Answer:
Parentals: PP (purple) and pp (white)
F1: Pp (purple)
Explanation:
When the two parental plants of differing phenotypes (purple or white flowers) cross, the F1 is 100% purple. This result suggests that the parentals were true breeding (homozygous), with purple flowers being the dominant allele.
When the F1 self pollinates, the F2 shows proportions very similar to 3/4 purple and 1/4 white (401/532 ≅ 3/4 and 131/532 ≅ 1/4). The 3:1 phenotypic ratio is typical of the offspring resulting from a cross between two heterozygous individuals.
The results make sense if the genotypes of the different generations are:
Parentals: PP (purple) X pp (white)
F1: Pp (purple)
F2: 1/4 PP, 2/4 Pp, 1/4 pp
