What happens during photosynthesis?
sashaice [31]

Answer: D. Autotrophs produce organic molecules

During photosyntheis, plants make sugar(an organic molecule and a type of carbohydrate). Photosynthesis occurs in autotrophs only, the organisms which are able to make their food like plants. Plants take air and water and produces glucose in presence of sunlight( a photochemical reaction). The product of the reaction is glucose which is one of the four types of organic molecule which is use by plants to make cells and their parts and growth.

Heterotrophs are the organisms which cannot make their own food and rely on other organisms for nutrients. Hence option 1 and 2 cannot be the part of answer. While the plants consume inorganic nutrients(decayed matter) from soil.

What is the mass of all the worker bees in the hive together? Write your answer in scientific notation.
Lisa [10]

Answer:

4 × 10^0 kg or 4×E0 kg.

Explanation:

Before delving into or solving the Calculation, let us check one or two things about worker bees.

WHAT IS A WORKER BEE?.

Bees generally are social insects living in an organized community and they consist of three castes which include; the drone bees, worker bees, and the queen bees.

The queen bees are the female bees while the drone bees are the male bees.

The WORKER BEES are female bees too, but the only difference between them and the queen bees is that they (worker bees) do not reproduce like the queen bees. They are saddled with the responsibility of looking for food and maintaining the hive temperature.

Now to the question, the mass of a bee= 1 × 10^-4 kg. And there are 4 × 10^4 bees in hive. Therefore, the mass of all the worker bees in the hive together = (1 × 10^-4) × (4×10^4).

==> 4 × 10^0 kg, or 4E0 kg.
