Answer:
Stratum Granulosum
Explanation:
The stratum granulosum is a layer of the epidermis and consists of four to six cell layers. The keratinocyte appearance changes in the cell layers of stratum granulosum as some cells stop dividing and the process of keratinization starts. Keratinization includes filling the cells with the protein keratin. During keratinization, the cells flatten, and the disintegration of their nuclei and organelles occur.
Due to the loss of the nucleus, these cells cannot divide and become dead. The keratinized cells accumulate keratohyalin granules and lamellar granules. The cells of this layer have thick plasma membrane due to the binding of cytosol proteins bind to the inner membrane face and coating of the external surface of the membrane by lipids of lamellar granules.
Answer:
Gamtetes are sex cells, for humans, this manifests as the sperm cell and the egg cell.
Explanation:
Gametes are haploid cells unlike most of our body cells that are diploid cells.
Answer:
Gregor Mendel
Explanation:
He used pea plants in the 1800s to explain the principles of inheritance. He used simple traits such as color and height to show the laws of independent assortment where trait from the parent peas are independently and randomly passed down to offspring. He also showed the law of segregation where genes occur in pairs (alleles) and where offspring inherited only one of the allele from each parent.
Answer:
surfaces curving inward, so it makes parallel light rays curve outward or diverge. That's why concave lenses are sometimes called diverging lenses. ... The distance from the center of the lens to the focal point is, again, the focal length of the lens.
