Mitosis occur in somatic cells while meiosis occur in the germ cells to produce gametes.
MITOSIS:
Two diploid daughter cells form that are genetically identical the parent cell.Homologous chromosomes do not pair in mitosis.In mitotic cells one row of chromosomes line up at the center.The nucleus of the cell divides only once.MEIOSIS:
Four haploid daughter cells form that are genetically different to the parent cell.Each homologous chromosome pairs after replication.Tetrads or group of four cell form and crossing over sometimes occur.Paired homologous chromosome line up across the center of the cell.Therefore, mitosis occur in somatic cells while meiosis occur in the germ cells.

Answers
2. Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. It is also defined as the measure of the tendency of a solution to take in pure solvent by osmosis.
3. The semipermeable membrane limits the diffusion of solutes in the water.
4. In an isotonic solution, the flow of water in and out of the cell is happening at the same rate. ... Water moves into and out of cells by osmosis.
5. Osmosis is basically diffusion with water. ... The most common example of facilitated diffusion is the movement of water across a cell membrane through transmembrane proteins, which requires no energy. They are simply powered by the concentration differences of the molecules between the two sides of the cell membrane.

Optimal activation of transcription of the GAL genes in yeast requires the function of two proteins: Gal4p and Gal11p. Elimination of either protein decreases activation of the GAL promoters. However, inactivation of Gal11p has the additional and dramatic effect of cell lethality. Why might elimination of Gal11p have a greater effect than elimination of Gal4p
Answers
Answer:
Gal4p is a transcription factor that targets specific GAL genes, while Gal11p is a core component of the Mediator complex that plays regulatory roles in the expression of many different genes (class II genes) in eukaryotic organisms
Explanation:
The Gal4 transcription factor is one of the most widely studied eukaryotic transcriptional activators capable of activating the expression of galactose-induced genes. Gal4 is well-known to target specific enzymes involved in galactose metabolism: GAL1, GAL7, and GAL10. On the other hand, Gal11p is a key subunit of the evolutionary conserved Mediator complex that binds to the RNA polymerase II (RNAP II) in order to regulate the transcription of class II genes (i.e., genes transcribed by RNAP II).

- These contain photosynthetic pigment in plastics!
3) Fungi:
- Fungi are eukaryotic organisms means they have a true nucleus which is enclosed in membranes.
- They are non-vascular organisms!
4) Protista:
- Protists have a nucleus containing their DNA.
- They also have other membrane-bound organelles, such as mitochondria and the endoplasmic reticulum!

Which of the following
is not a type of lipid?
A. Fat
B. Steroids
C. Sugar
D. Waxes
Answers
Pretty sure the answer is Sugar, Correct me if I'm wrong
Sugar is not a lipid, but it is a carbohydrate. Thus, option C is correct.
What is lipid?Lipid is type of biomolecule, consisting, fats, steroids, waxes, and fat soluble vitamins such as A, D, E, K and others. It is an organic molecule which is hydrophobic or amphiphilic molecule which is insoluble in the water.
Fatty acids are included in the class of carboxylic acids which has long hydrocarbon chain and terminal carboxyl group (COOH). As compare to other molecules found in food that are carbohydrates and proteins, lipids contain more than twice energy.
Lipids play significant role in cell signaling as lipid signaling, which is very vital part of it. It is also involved in immunity, hormones such testosterone, estrogen, cortisol. Fat soluble vitamins play an important role in nutrition.
Therefore, sugar is carbohydrate not lipid. Therefore, option C is correct.

True breeding plant round seeds (DD) were bred with true breeding smooth
seeds(dd) to produce F1 offspring. F1 offspring were then bred with other F1
offspring. What is the genotypic ratio of the resulting F2 offspring? What is the
phenotypic ratio of the resulting F2 offspring?
Answers
Answer:
Genotypic ratio F2 = 1:2:1
Phenotypic ratio F2 = 3:1
Explanation:
In this case, parental genotypes can produce only one type of gamete, i.e., one parent can produce only D gametes, while the other parent can produce only d gametes. Therefore, all F1 generation will be heterozygous (Aa). An F1 hybrid is the first filial generation of offspring obtained from crossing between different parent types. The F1 will produce two gametes (A; a) in a ratio 1:1, thereby the F2 obtained by crossing F1 offspring will have a phenotypic ratio of 3:1 (3 D_; 1 dd) and a genotypic ratio of 1:2:1 (1 AA; 2 Aa; 1 aa).
