B) On the same place on the same chromosome.
Explanation:
Both alleles are located on the same chromosome and present at the same place because genes come in pair. Each pair of gene is located at a specific place on a chromosome. If the two alleles present at a specific location are similar to each other, it is called homo-zygous while on the other hand, if both alleles are different from one another, they are considered as hetero-zygous.
The answer to this question is Prokaryotes
Answer:
The three types of rocks are Igneous, Sedimentary, and Metaphoric.
Explanation:
<em>Igneous</em> rocks are formed out of melted rocks deep inside the Earth. A distinguishing unique characteristic is that they are hard.
<em>Sedimentary</em> is formed from layers of sand, silt, dead plants, and animal skeletons. A distinguishing unique characteristic is that they are easy to crumble.
<em>Metaphoric </em>are formed when minerals change through heat and pressure underground. Two distinguishing unique characteristics are that they may have many layers and are noticeably hard.

known mutagens in today’s conventional diet includes:
1.)Nitrates and nitrites (N-nitrosamines), naturally occurring chemical compounds that are legal preservatives used to suppress harmful bacteria in a variety of cured meats and some cheeses.
2.)Polycyclic aromatic hydrocarbons (PAHs); food contamination by PAHs arises from processing of food (drying, smoking) and cooking of food at high temperatures (grilling, frying, roasting).
3.) Heterocyclic amines (HCAs), many of which are present in burnt and charred foods, especially blackened meat.
1- Red color has the longest wavelength. Red light belongs to the visible spectrum of light and the wavelength of visible spectrum ranges from 700nm to 400nm, from red to violet respectively.
2- Gamma rays, x-rays, visible light and radio waves are all types of electromagnetic radiations. Electromagnetic radiations contain visible light, radio waves, gamma rays and x-rays. These radiations has varied electric and magnetic fields.
3- The fact that light can exert a pressure on matter suggests that it is made up of photons.
