A geneticist studying fruit flies finds that out of a total population of 400 he observes only 12 flies with red eyes, the rest have black eyes. The percentage of flies with red eyes is

Answers

Answer 1
Answer:

The question says that in a population of 400 flies, only 12 had red eyes.

The total number of fruit flies in this case is 400.

and

The total number of flies having red eyes is 12.

To find out the percentage of fruit flies having red eyes, following formula is used:

\frac{\textup{total number of flies having red eyes}}{\textup{total number of flies}}* 100

So, the percentage of red eye individual is;

(12)/(400)* 100 \n \n=3

Hence, the total percentage of red eye offspring is 3%.
Answer 2
Answer:

Given: Total population of flies is 400, number of flies with red eyes is 12.

To find: The percentage of flies with red eyes.

Method: We know the total number of red eyed flies and the size of population. The percentage can be found by diving the number of red flies by the size of the population of the flies.

Solution:

Percentage of red eyed flies = (12 * 100)/(400) = (3*100)/(100) = 3

Hence the answer is 3% of the flies are red eyed.

The leaves of plants have layers that perform different functions. The _____ layer contains the chlorophyll, which carries out most of the photosynthesis in the leaf.upper epidermis
palisade
spongy
lower epidermis

Answers

The leaves of plants have layers that perform different functions. The palisade layer contains the chlorophyll, which carries out most of the photosynthesis in the leaf.In the palisade layer, the cells are arranged in an upright fashion. This means the light has no choice but to pass through the cell length ways which increases the chances of light hitting a chloroplast and subsequently being absorbed.The spongy layer which is below the palisade layer has fewer chloroplasts and serves to catch the light that was not captured by the palisade layer.

Answer:

The leaves of plants have layers that perform different functions. The palisade layer contains the chlorophyll, which carries out most of the photosynthesis in the leaf.

Which of these phrases BEST describes atoms?Select one:
a. two or more combined elements
b. the smallest units of an element
c. particles inside a nucleus
d. different forms of an element
Next

Answers

the answer is ..b .the smallest units of an element ...

Hope it helps !!!

Final answer:

Atoms are best described as 'the smallest units of an element', because each different kind of atom corresponds to a different element. Atoms are themselves composed of protons, neutrons, and electrons.

Explanation:

The phrase that best describes atoms is 'the smallest units of an element' (option b). This is because atoms are the basic pieces that make up all matter, and every different atom corresponds to a different element. An atom itself is composed of sub-atomic particles: protons and neutrons are stacked up into the nucleus at the center of the atom, while electrons orbit the nucleus in various energy levels.

Which parts of the spectrum does chlorophyll a absorb best? answers?

Answers

Chlorophylls (green pigments of the plant) absorb light most strongly in the blue portion of the electromagnetic spectrum, but also the red portion. On the other hand, chlorophylls are a poor absorber of green portions of the spectrum, which it reflects and thus produce the green color of chlorophyll-containing tissues (that’s how plants are green).
