I think the correct answer from the choices listed above is the last option. It would be 50 <span> full-length strands of hair are collected from the scalp to use as a sample. The more sample the better because you can easily repeat an experiment if there are errors found. Hope this answers the question.</span>
Answer:
plant
are the example of muscle cells
Radioactive decay (also known as nuclear decay, radioactivity or nuclear radiation) is the process by which an unstable atomic nucleus loses energy (in terms of mass in its rest frame) by emitting radiation, such as an alpha particle, beta particle with neutrino or only a neutrino in the case of electron capture, or a gamma ray or electron in the case of internal conversion. A material containing such unstable nuclei is considered radioactive. Certain highly excited short-lived nuclear states can decay through neutron emission, or more rarely, proton emission.
Answer:
Cross overs can lead to formation of chromosome pairs that have no mutant allele.
Explanation:
Cross overs can lead to formation of chromosome pairs that have no mutant allele.
For example -
Suppose "X" is a mutant allele and "x" is a mutant free allele.
Now when two homologous chromosomes contains a single mutant allele in different parts of the chromosome are crossed the following offspring are produced
X x
X XX Xx
x Xx xx
"xx" is a mutant free genotype.
Thus, crossing over can create a single mutation-free chromosome
Answer:
It's possible.
Explanation:
If the recently formed metamorphic rock keeps on warming, it can ultimately soften and become molten (magma). At the point when the liquid stone cools it frames a molten rock, which is igneous. Metamorphic rocks can form from either sedimentary or volcanic/igneous rocks.
