Until DNA evidence provided evidence to the contrary, flagellated spores were used to group the blastocladiomycetes with the ____.

Answers

Answer:

Chytridiomycetes

Explanation:

Blastocladiomycetes were initially grouped under the phylum Chytridiomycetes within the fungi kingdom because the former also have flagellated spores just like the latter

The similarity in spores initially made scientists classify both groups as zoosporic fungi. However, DNA and structural analysis of the spores of the two groups showed that Blastocladiomycetes has no monophyletic relationship with Chytridiomycetes.

A founding population usually has lower genetic diversity than the original population it came from. For those alleles that are shared by the two populations, how are allele frequencies different (or similar)

Answers

Answer:

In the founding population, the allele frequency is different from the original bigger-sized population. The size of the new population affects this difference even more. Some of the alleles will tend to increase, while some others will tend to decrease in frequency.

Explanation:

Genetic drift is an evolutive force. It is the random change that occurs in the allelic frequency of a population through generations. Its effects are harder in a small-sized population, meaning that the magnitude of this change is inversely related to the size of the original population.  

Genetic drift results in some alleles loss -including the beneficial ones-, while some other alleles get fixated. Low-frequency alleles are the most likely to be lost. The changes produced by genetic drift accumulate in time and results in a loss of genetic variability within a population.  

Genetic drift affects a population and reduces its size dramatically due to a disaster or pressure -bottleneck effect- or because of a population split -founder effect-. The bottleneck effect most likely affects smaller populations.  

Founder effect refers to the origin of a new population from only a few individuals that are coming from a bigger-sized population. These founder individuals, which are carrying some of the genes of the original population, settle down in a new area and reproduce. The new and small population might or might not be genetically representative of the original one. Some rare alleles might be exceeded or might be lost by complete. Consequently, when the small population increases in size, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced, and there exists the possibility of developing a peculiar allelic composition. When the number of individuals that originated the new population is low, the founder effect will be very extreme because the genetic drift effects are inversely proportional to the original number of individuals.

d. The concentration of reactant molecules must be reduced.

Answers

Answer:

Your answer would be B

Explanation:

In order to start a chemical reaction, energy is needed

Answer:

Option B

The activation energy must be reached.

You may have heard through various media of an animal alleged to be the hybrid of a rabbit and a cat. Given that the cat (Felis domesticus) has a diploid chromosome number of 38 and a rabbit (Oryctolagus cuniculus) has a diploid chromosome number of 44, what would be the expected chromosome number in the somatic tissues of this alleged hybrid

Answers

Answer:

The correct answer is - 2n = 41 chromosomes.

Explanation:

It is given that the cat has a diploid chromosome number of 38 while the rabbit has a diploid number of 44 chromosomes and if they form a hybrid then their expected chromosome number in somatic cells would be -

Cat (2n=38) produces haploid gametes with 19 chromosomes (n-19).

Rabbit (2n=44) produces haploid gametes with 22 chromosomes(n=22)

19+22= 41 chromosomes in the particular hybrid as half number of chromosomes come from each parent.

What different gland and hormones are involved in the production of amino acids

Answers

Answer:

Amino acid generated from tyrosines and tryptophan (end in '-ine') and includes adrenaline and norepinephrine. The (produced by the adrenal medulla). Thyroxine (production from the thyroid gland) and melatonin are also included in the amino acid hormones (produced by the pineal gland).

Explanation:

The main control over hormone production and release is negative feedback. The stimulation causes the release of a chemical in negative feedback systems; once it reaches a specific level, the substance sends a signal stopping further discharge.

This ensures a narrow range of the levels of hormones in the blood.

For example, blood glucose is controlled via negative feedback to secrete insulin and glucagons.

What is the elevation of point B

Answers

Answer: c. Point B has an elevation less than 2750 feet.

Explanation:

The lines drawn on the map are known as contour lines and they are used to measure elevation. Point B is on a river and rivers are only able to flow at a lower elevation than the area around them.

Point B is therefore lower than the area around it and as the closest contour line to it puts the area at an elevation of 2,750 feet, that must mean that Point B is lower than 2,750 feet.

a scientist is observing a eukaryotic cell and a prokaryotic cell. which structure could she only observe in the eukaryotic cell?

A.) cytoplasm

B.) DNA

C.) ribsomes

D.) Nucleus​

Answers

Answer:

The answer is D. Nucleus are only found in Eukaryotes.

Answer: D.) Nucleus

Explanation: In the question, we are told to find a structure that is found ONLY in eukaryotic cells. Because of this, we have to eliminate any option that is found only in prokaryotic cells, or any that is found in both prokaryotic and eukaryotic cells. In options A-C, we are given structures found in both types of cells. The cytoplasm, DNA, and ribosomes differ in each type of cell; however, nevertheless, they do not only appear in eukaryotic cells. This makes nucleus the only valid option, as it is only found in eukaryotic cells.
