The right answer is C.

Meiosis and fertilization contribute to the stability of the species.

Meiosis ensures the passage of the diploid phase to the haploid phase. It follows a phase of DNA replication and consists of two successive divisions, the second is not preceded by a duplication of DNA. These two divisions lead, from a diploid mother cell (2n chromosomes), to four haploid daughter cells, the gametes (n chromosomes).

Meiosis and fertilization are at the origin of genetic mixing.

During meiosis, intra- and interchromosomal mixing occurs (inducing a genetic diversity between the daughter cells, and they are systematically different from their mother cell).

*Intrachromosomal mixing, or crossing-over recombination, takes place between paired homologous chromosomes during the prophase of the first meiosis division;

*Interchromosomal mixing is due to the independent migration of the homologous chromosomes of each pair during anaphase of the first division. It therefore concerns chromosomes reworked by the intrachromosomal mixing that preceded it.

Why is the process of photosynthesis affected by the process of cellular respiration
cluponka [151]
Since photosynthesis is a process that uses co2 and cellular respiration is the process to create co2, if there aren’t any processes of cellular respiration to create the co2 needed in the photosynthesis, it wouldn’t happen.

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.

Genetic engineering is the process of manipulating genes for practical purposes. Today, scientists have genetically engineered m
konstantin123 [22]

Your answer would be C because A affects the natural environment and can cause harm to it, B would affect the surrounding animal population and cause imbalances in biodiversity if they are not able to eat the foods they are used to, and D is not much of a benefit since you are losing the flavor that is naturally in the plants.

What is happening to the carrying capacity of the bees
coldgirl [10]

Bee colonies are currently weaker than ever, making bees unable to carry pollin. The carrying capacity of the bees are <em>decreasing</em> because the population of bees are also decreasing.
