<u>Answer:</u>
<em>Dark rich organic material formed as a top layer in soil from the decayed remains of plants and animals is called humus. </em>
<u>Explanation:</u>
When dead parts of plants and animals are deposited in soil the <em>decomposing bacteria present in the soil act on these remains and break them down. </em>
Plant and animal bodies contain organic compounds which are broken down into inorganic nutrients by the decomposers. These nutrients are taken up by producers and the nutrients restart their journey in the food chain.
<em>Humus is identified by its rich dark color. The amount of humus decides how fertile the soil is. More the humus content fertile is the soil. </em>
Decomposition is the process by which organic substances are broken down into a more simple organic matter. The process is a part of the nutrient cycle and is essential for recycling the finite matter that occupies physical space in the biosphere. Bodies of living organisms begin to decompose shortly after death. Animals, such as worms, also help decompose the organic materials. Organisms that do this are known as decomposers.
hope this answer helps you!!
Answer: Yes and No
Explanation: I think that we should use technology to alter our genetic code if someone is ill/sick because it is actually beneficial, but I think we shouldn't dive too deep or get lost in altering genes because it can cause unintended consequences.
The zygote simply is the fertilized ovum or egg cell or female reproductive cell. It is the result of the process of fertilization of the fusion of the male reproductive cell (gamete) and the female reproductive cell ( gamete). In human, the zygote is the resulted cell of fertilization of the sperm and the ovum. It is diploid or 2N which means it contains two sets of chromosomes; one set from the male and the other from the female.
The gamete is the reproductive cell. There are two types of gametes; male gamete and female gamete. In human, the male gamete is called the sperm and the female gamete is called the ovum. The gamete is the last stage of the reproductive cells to be completely formed.
Fertilization is the fusion of the male gamete and the female gamete to form the zygote. Fertilization may be external as in fish or internal as in human.
