Answer:
If two heterozygous pea plants are crossed with yellow round seeds, the resulting progeny mostly show the dominant phenotype.
Explanation:
Plants with two different alleles of a gene are heterozygous. As all the heterozygous offspring are yellow, then the yellow allele must be dominant over the recessive green allele.

Answer:
<em>Endothermic reactions: separation of solute molecules , separation of solvent molecules</em>
<em>Exothermic: formation of solute-solvent interactions</em>
Explanation:
An endothermic reaction can be described as a reaction which requires energy. Usually, the energy is taken in the form of heat from the environment. For example: the separation of solute and solvent molecules.
An exothermic reaction can be described as a reaction in which energy is released during a reaction. For example, a solute and a solvent reaction. Energy is usually released in the form of heat during an exothermic process.
Answer:
Ll, Ll, LL
Explanation:
So, there is one thing we must remember to answer this:
1# dominant genes(long fur) are expressed over reccesive genes(short fur)
Knownign that dominant is over reccesive, it is simple. If the genotype was Ll or lL then the dominant long fur would be expressed over reccesive short fur. <u>Long fur - Ll, lL</u>
Next, we know that LL will be long fur since its both long and long, and there is no possibility for short fur. <u>Long fur - LL</u>
Finally. we have ll, and since there isnt a dominant long fur, and only reccesvie short, then this cannot be long fur. Short fur. - ll
<h3><u>Answer;</u></h3>
In metaphase I, the chromosome tetrads align on metaphase plate
while in metaphase II, chromosomes align on metaphase plate as they are in mitosis with only sister chromatids.
<h3><u>Explanation;</u></h3>
- Meiosis is a form of cell division that halves number of chromosomes when forming specialized reproductive cells such as gametes
.
- Meiosis occurs in two phases, namely; meiosis I and meiosis II. During homologous pairs of chromosomes align on the equatorial plane at the center of the cell.
- During metaphase II, the spindle fibers connect to the kinetochore of each sister chromatid. The chromosomes align at the equatorial plane, which is rotated 90° compared to the equatorial plane in meiosis I.
