c. numbers of neutrons.

Isotopes are atoms of the same element with the same number of protons and same number of electrons but with different number of neutrons. They differ in the number of neutrons that is why they also differ in mass numbers. Since they have the same number of protons, they have the same atomic number.
For instance, when the nucleus of the isotope with a 68.926 amu, there are 30 protons and 39 neutrons in the nucleus. The best example for this is Zn (zinc-69 isotope) and Ga (gallium-69 isotope) which has 68.926 amu and 68.925 amu respectively.

saveliy_v [14]

The probability of the offspring having a bent finger is 100% we can calculate this using a punnet square like one attached, where B is the dominant bent fifth finger and b is the recessive bent fifth finger, the man's genes are along the top and the woman's genes are along the side.

Bond [772]

Even though Eubacteria and Archaebacteria look similar, differences in their ribosomal RNA led to their classification into different domains. They are domains of the old kingdom Monera.

<h3>What are Archaebacteria and Eubacteria? </h3>

Archaebacteria and eubacteria represent two different domains of the old kingdom Monera.

Monera is formed by unicellular prokaryotic microorganisms that do not have membrane-bound organelles and cell nuclei.

Both Archaebacteria and Eubacteria exhibit sequence variation in their ribosomal RNA, which can be used to classify them.

Which of the following processes involves the chloroplast?a. cell divisionb. conversion of light energy to chemical energyc. for

tino4ka555 [31]

Answer:

$\boxed{\tt B. \ Conversion\ of\ light \ energy \ to \ chemical \ energy}$

Explanation:

This question asks us which process involves the chloroplast.

In plants, algae, and some bacteria, a process called photosynthesis occurs. This process takes place in the chloroplasts. In the process, the organism takes light energy from the sun, carbon dioxide, and water, and turns it into glucose and oxygen.

The glucose that is made becomes the food and energy for the organism. In another process, called cellular respiration, the sugar is turned into ATP, a kind of useable energy.

The best answer choice is B. Conversion of light energy to chemical energy. The chloroplasts convert light energy to sugar, and the sugar becomes chemical energy.
