Carbon from bicarbonate is used for transformation of acetyl-CoA into malonyl-CoA. Bicarbonate gives only one carbon, and if it would give two (both) carbons, it would be lost. On the other hand, <span>two carbons are necessary </span>for the incorporation into the new fatty acid. So, the reason will be that bicarbonate cannot give an adequate amount of carbons, so it cannot be incorporated into the new fatty acid.
Answer:
Humans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa. Most scientists currently recognize some 15 to 20 different species of early humans.The first true primates evolved by 55 million years ago or a bit earlier, near the beginning of the Eocene Epoch. Their fossils have been found in North America, Europe, and Asia. They looked different from the primates today.

Reproductive success is defined as the passing of genes onto the next generation in a way that they too can pass on those genes. This is not solely the number of offspring produced by an individual, but also, as Ronald Fisher outlined in 1915, the probable reproductive success of those offspring, making mate choice (a form of sexual selection) an important factor in this success,[1] making biological fitness a key element in the theories of natural selection and evolution.
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.
Um there is no picture. I would love to help you though
