Answer:
1) the genes and chromosomes do not double after each generations because parental sex cells are haploid and only contain one set of chromosomes. During fertilization the two cells fuse to form a diploid zygote with two copies of genes and chromosomes. For example a normal human has 46 chromosomes (2 copies of 23 chromosomes) during reproduction gametes which contain 23 chromosomes (haploid) fuse to form an offspring with the correct number of chromosomes ( 23 + 23 = 46).
2) offspring only receive one set of chromosomes from each parent so to maintain the chromosome number of humans. If this did not happen you would not be the same species.
Answer:
The correct answer is option energy is a product.
Explanation:
Cellular respiration is a process in which oxidation of food or glucose takes place to produce energy. This process proceeds in four processes: glycolysis, oxidative carboxylation, Krebs cycle and electron transport chain.
All of this process produces energy in the form of ATP or energy equivalents like NADH and FADH₂.
1. Glycolysis produces- 2 ATP, 2 NADH,
2. Oxidative carboxylation produces- 2 NADH,
3. Krebs cycle produces- 2 ATP, 6 NADH AND 2 FADH₂ and
4. Electron transport chain produces at last- 24 ATP from these reducing equivalents.
Thus, option energy is a product is a correct option.
Answer:
Foresters are responsible for determining areas that can be harvested sustainably and helps monitor areas to be harvested. Foresters determine which areas have trees that can be removed without causing harm to the environment and ensures that areas are not overharvested.
Explanation:
Answer:
F1 Females - all wild type
F1 Males - all wild type
F2 Females - - all wild type
F2 Males - 1/2 wild type, 1/2 vermilion
Explanation:
The wild-type allele (Xᵛ⁺) is dominant over vermilion (Xᵛ), which is a sex-linked trait.
Female flies have two X chromosomes, male flies have one X and one Y chromosome.
A homozygous wild-type female fly (Xᵛ⁺Xᵛ⁺) is mated with a vermilion male fly (XᵛY).
The female parent can only produce Xᵛ⁺ gametes.
The male parent can produce either Xᵛ or Y gametes.
When gametes from both parents fuse, the F1 offspring will have the genotypes Xᵛ⁺Xᵛ (females with wild type eyes) and Xᵛ⁺Y (males with wild type eyes).
The F1 females can produce Xᵛ⁺ and Xᵛ gametes. The F1 males can produce Xᵛ⁺ and Y gametes.
When the F1 individuals interbreed, the gametes combine to give rise to the F2 offspring. The possible combination of gametes that will give the different genotypes and phenotypes in the F2 are:
- Xᵛ⁺Xᵛ⁺ females with wild type eyes
- Xᵛ⁺ Y males with wild type eyes
- Xᵛ Xᵛ⁺ females with wild type eyes
- Xᵛ Y males with vermilion eyes
Answer:
You need to make sure the dressing is in a good place, because once its on the salad, it cannot hold really well. Well that really depends on the dressing. More liquidy dressings will make your salad soggier faster. So to help with this, you can add herbs, vegies, meat, even some fruit to help soak up the dressing a bit.
Explanation:
I'm not a 100% sure but I hope this helps.
