Answer:
<em>When a baby is born, the zygote has become about </em><em><u>26 </u></em><em>billion cells</em>
Explanation:
Cell: Cell is defined as the structural and functional unit of living thing. I.e The cell is the simplest and the basic unit of life. All living things are made of cell.
Zygote: A zygote is a single cell formed from the union of a male cell called sperm and a female cell called egg.
<em>When a baby is born, the zygote has become about </em><em><u>26 </u></em><em>billion cells</em>

Mutations can occur before, during, and after mitosis and meiosis. If a mutation occurs in cells that will make gametes by meiosis or during meiosis itself, it can be passed on to offspring and contribute to genetic variability of the population
Answer:
The amount of organic matter in mineral (sand, loam or clay) soils ranges from very low being 1% by weight, to average being 2 to 4%, and high being greater than 5%. There are also “muck” or organic or peat based soils that are 30 to 40% organic matter. The general consensus is the more soil organic matter the better. approximately 45%
Soil Composition
The basic components of soil are minerals, organic matter, water and air. The typical soil consists of approximately 45% mineral, 5% organic matter, 20-30% water, and 20-30% air. These percentages are only generalizations at best.

The correct answer would b c
Answer: They lack nucleus and other organelles important for the synthesis of the enzyme.
Explanation:
The main function of the red blood cells is to supply oxygen throughout the body. The oxygen binds to the hemoglobin and travels throughout the body to ensure the supply of oxygen to various organs and more precisely the cells of the body.
The enzymes that is being synthesized inside the body is produced by the help of the gene and nucleus along with the other organelles involved in it.The mature red blood cells lack nucleus in order to increase the surface area for carrying the oxygen.
As there is no nucleus, mitochondria and golgi apparatus in the cell, there is no enzyme synthesis and broke down in the cell.
