A cell in the leaf of a corn plant contains more chloroplasts than a cell in the stem of a corn plant. Based on this observation
Alik [6]

Answer:

This question lacks options, the options are:

A). synthesizes more sugar

B). has a higher chromosome count

C). produces fewer proteins

D). uses less carbon dioxide

The answer is A

Explanation:

The chloroplast is an organelle present in the cells of photosynthetic organisms. It is the site where photosynthesis, which is the production of food (sugars) from sunlight energy, occurs.

According to this question, a cell in the leaf of a corn plant contains more chloroplasts than a cell in the stem of the same corn plant. Based on this observation, it can be inferred that the LEAF CELLS WILL SYNTHESIZE MORE SUGARS THAN THE STEM CELL because the more the chloroplast, the higher the photosynthetic rate and subsequently the higher the amount of sugar produced.

0.00632 into a scientific notation
ddd [48]

Answer:

6.32 × 10⁻³

3.2560008× 10⁷

5.630× 10⁰

9.5002× 10¹

Explanation:

Scientific notation is the way to express the large value in short form.

The number in scientific notation have two parts.

The digits (decimal point will place after first digit)

× 10 ( the power which put the decimal point where it should be)

For example:

0.00632

In scientific notation =  6.32 × 10⁻³

32,560,008

In scientific notation  = 3.2560008× 10⁷

5.630

In scientific notation  = 5.630× 10⁰

95.002

In scientific notation  = 9.5002× 10¹
