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.

When you hear the term mutation, you usually think of change. But how do mutations influence traits that may be inherited?
lana [24]

Hereditary mutation - may be passed to another generation, occurs in gametes, variation that may enhance survival.

Somatic mutation - not passed from generation to generations, occurs in body cells.

Both- changes in DNA.

<h3><u>Explanation:</u></h3>

Mutations are defined as sudden changes in DNA that takes place by changing a particular nucleotide or a portion of DNA, or even a whole chromosome which has potential to change characters of an organism. Mutation was first proposed by Hugo de Vries who is also known as the Father of Mutation Theory.

Mutations can occur in any cell of body. It may occur in somatic cells, or in germ mother cells. But the mutations that occur in germ mother cells are actually the mutations that are carried forward by the gametes into next generations. Mutation in somatic cells get obliterated as the organism dies. And the Mutation in gamete cells are those mutations which are capable to cause variations in progenies which can led to better survival of the progenies.

Answer:

Cells divide twice

Explanation:

Meiosis may be defined as the process of cell division in which a single cell divides to give four daughter cells and each daughter cells  have half number of chromosomes.

Meiosis is also known as reduction division as the chromosome number reduces upto half in the progeny cells as compared with the parent cell. The cells divide twice in meiosis and give rise to four daughter cells.

Thus, the correct answer is option (4).
