Answer:
Root hair cells are alive and therefore need energy, which is why root hair cells contain many mitochondria in them. Root hair cells don't contain chloroplasts. Chloroplasts are used by the plant to make food using light energy. Since the roots aren't exposed to any form of light, they have no need for chloroplasts.
Rather, physicists believe the Big Bang created and stretched space itself, expanding the universe. As the early universe cooled, the matter produced in the Big Bang gathered into stars and galaxies. For a brief moment after the Big Bang, the immense heat created conditions unlike any conditions astrophysicists see in the universe today.
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.
Answer:
All require at least one protein cofactor.
Explanation:
Translation is the process of the formation of the proteins from the different RNA molecules, enzymes and the cofactors. The translation process involves the movement of ribosomes over mRNA.
The three important process of translation are initiation, elongation and termination. All these steps require different enzymes and protein cofactors. The initiation requires the initiation cofactors like eIF, elongation require additional cofactors and same with the termination of translation.
Thus, the correct answer is option (1).
