Each kernel of corn receives one allele from
each parent for the traits of color and texture.
Option B
<h3><u>Explanation:</u></h3>
Corn kernels are actually the seeds of corn. Corn kernels are formed because of the fertilization of both the Pollen and the ovule of the corn plants. This pollens and the ovules are formed by means of meiosis which takes different alleles of the same gene from both the parents and both the chromosomes of each parents. This is why during meiosis the events of crossing over and independent assortment leads to the variation of characters into the offspring. This is why the kernel colours of the the same ear of the corn remains same. This is how the corn plant receives the the kernel colours from both the parents and their colours remain constant for one particular ear. Also the gene of texture is achieved from both the parents by means of meiosis just like the corn colour. So there also independently assorted.
This is false. DNA transcription is the first step in gene expression.
I'm gonna say A. Lungs, heart, and brain pumps all the blood through your system. Or B.
Answer:
yes,because rabbit is one of the food sources of fox .If rabbit population decrease, fox population will also decease due to lack of food.

Explanation:
For metals, the further away the valence electrons are from the nucleus, the higher the reactivity of the elements. Unlike halogens that are more reactive if the valence orbital shells are closer to the nucleus. This is due to ionization energies – which is the minimum energy required to discharge an electron from its orbit.
For metals this should be lower because they need to lose electrons to attain a stable electron configuration. For halogens it should be high because they don't need to lose electrons, but rather gain, in order to attain stable electron configuration.
Electrons in their orbital shells need to occur in pairs (with opposite quantum states) to be in stable configuration and as long as an atom has orbitals with single electrons, the atoms will be reactive as opposed to when its orbitals are ‘full’.
