Answer:

Genotypic probability = 1RR: 2Rr: 1rr

Phenotypic probability = 1Red: 2Pink: 1white

Explanation:

This question involves a single gene coding for skin color in snapdragon plants. The alleles are incompletely dominant over one another and hence, produce an intermediate pink phenotype.

According to this question, two pink/heterozygous snapdragons were crossed i.e. Rr × Rr. Each parent will have gametes R and r. Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

Genotypic probability = 1RR: 2Rr: 1rr

Phenotypic probability = 1Red: 2Pink: 1white

Answer:

The correct answer is: The ventromedial hypothalamus plays a role in satiety.​

Explanation:

The hypothalamus is a part of the brain that controls many important bodily functions and connects both the nervous system with the endocrine system. The hypothalamus consists of several nuclei that have diverse functions and are located in 3 different regions.

The nucleus that plays a role in satiety is the ventromedial nucleus, terminating hunger and giving a sensation of fullness. It also plays a significant role in thermoregulation, among other things.

Neuropeptide Y, on the other hand, is a peptide that is released to make us feel hungry and encourage us to intake food (primarily carbohydrates).

Cholecystokinin is a hormone released by the small intestines after we had a meal, and its function is to improve digestion and make us feel full.

Fat cells DO release leptin, but the function of this hormone is to produce satiety, by stimulating anorexigenic (meaning they take hunger away) hormones and inhibiting orexigenic ones, like Neuropeptide Y.

Answer:

Explanation:

I took the quiz and got that answer

Answer:

1. HETEROzygous - Having 2 diff.alleles for a gene

2. Dominant - Allele whose trait is always expressed

3.Recessive - Allele whose trait is hidden unless paired.......

4. genotype - the genetic makeup of an individual

5.phenotype - the physical charact.of a trait

6.honozygous - having 2 identical alleles for a gene

Answer:

is d. The bacteria have high genetic variability and high reproductive rates.

Explanation:

Answer:

Explanation:

Genetic diversity is of fundamental importance in the continuity of a species as it provides the necessary adaptation to the prevailing biotic and abiotic environmental conditions, and enables change in the genetic composition to cope with changes in the environment.

Answer:

An introduced species, alien species, exotic species, adventive species, immigrant species, ... Non-native species can have various effects on the local ecosystem. ... Some species have been introduced intentionally to combat pests

Answer:

Explanation:Antibodies work by recognising and sticking to specific proteins, such as those found on the surfaces of viruses and bacteria, in a highly specific way. When the body encounters a microbe for the first time, immune cells produce antibodies that specifically recognise proteins associated with that particular microbe.

Answer:b) Nucleotide, chromosome, nitrogenous base, nucleus, DNA.

Volcanic Eruption

Explanation:

(I also know because I took the quiz) The volcano is the one that rapidly changes. It can erupt any time.

Forest Succession is slower than a volcanic eruption. It might take years for the trees in a forest to grow and for the population of animals to get there. It has to be just right, it needs all the plants and animals for it to be a forest, well not all of it but most of it.

Decomposition is also slower than a volcanic eruption.

Tree growth takes a long time. It might not even be a full tree until years later. It also takes time and water.

Answer:

The types of volcanoes that I am aware of are dormant, active, and extinct. Active volcanoes are volcanoes that have erupted in the past 10,000 years. Dormant volcanoes are active volcanoes that are supposed to erupt in the future. Extinct volcanoes are volcanoes that have not had an eruption in the last 10,000 years and is not expected to erupt.

Explanation:

coral skeletons are biocomposites (mineral+organics) or calcium carbonate

Answer:

Explanation:

In s phase, the dna replication take place in interphase, The dna in the nucleus replicates so that each chromosome consists of two identical chromatids, then in mitosis they are pulled apart in anaphase in which both cells have half of the chromosomes, in Telophase each chromatid contains one dna molecule, which will replicate itself during interphase before the next division.

The new cells are similar from the original ones in interphase as these will have same amount of DNAs.

The interphase phase of the cell cycle is where the majority of the life of a typical cell occurs.

Interphase is the cell's "daily living" or metabolic phase, during which it obtains and metabolizes nutrients, grows, replicates its DNA in preparation for mitosis, and performs other "normal" cell functions.

The cell cycle's longest phase is interphase. This is the stage at which the cell grows and copies its DNA before entering mitosis.

Chromosomes align, separate, and move into new daughter cells during mitosis. Because the prefix inter- means "between," interphase occurs between mitotic (M) phases.

In interphase, the new cells are similar to the original ones because they have the same number of DNAs.

Thus, this can be the similarity between these two.
