Answer:

Vacuoles regulate the turgidity by regulating the amount of water inside the cell. cell has excessive water: vacuole absorbs the water and then diffuses it out of the cell. cell lacks water: water from the vacuole gets passed back into the cell thereby maintaining turgidity

Answer:

phenotype

Explanation:

Genotype is the term which is responsible for the blue eyes in an organism because it occurs due to changes in genes.

The genotype of an organism refers to genes or genetic material of an organism. Genotype can also be refer to the alleles or variants an individual carries in a particular gene.

So we can conclude that genotype is the term which is responsible for the blue eyes in an organism because it occurs due to changes in genes.

Answer:

B. DNA unzips before step 1.

Explanation:

This question is describing the process of gene expression, which is made up of two major stages namely; transcription and translation. Transcription is the process by which mRNA is synthesized from a DNA template while translation is the process where protein (amino acid sequence) is produced using the mRNA transcript.

This stages of gene expression has been summarized in the steps listed by Shura. However, prior to the formation of an mRNA molecule in step 1, the double stranded DNA has to unwind i.e. separate into single strands as initiated by the enzyme RNA polymerase. Therefore, the list should read as follows:

- DNA unzips

- A strand of RNA is made.

- RNA leaves the nucleus.

- RNA moves to the ribosome.

- A protein is made.

Answer:

Cb>Cy>Co>Cr

Explanation:

First of al we need to do the Punnett square. As a result we get the genotypes:

CyCb

CyCr

CoCb

CoCr

Because there are no red frogs, red is the least dominant as it isn't expressed in any genotype.

Half of the progeny are blue and half of the possible genotypes contain the blue allele meaning that blue is expressed in all genotypes. This means that blue is the most dominant.

The only alleles left are yellow and orange. We can deduce that yellow is more dominant than orange because one of the parent frogs is yellow and contains the genes for yellow and orange.

As a result blue is the most dominant, yellow is the second most dominant, orange is the third most dominant and red is the least dominant.

Explanation:

In a Gel-Filtration chromatography, the larger molecules elude faster from the gel than the small ones.

In a Gel-Filtration chromatography, there is a stationary phase and a mobile phase. The stationary phase has beads with pores. Small molecules enter the beads and descend through these beads' pores. On the other hand, large molecules do not enter the beads' pores, so they go down through the mobile phase faster than the small molecules. Since they do not have the obstacle of the pores, they descend between the beads more fluidly. As a result, the larger molecules elute first from the gel than the small molecules.

Answer:

The correct answer is - option C.

Explanation:

Skiing generally happens on higher altitudes such as mountains. It is known that there is less oxygen is available at higher altitudes. There is low oxygen pressure at such height.

The prolonged increase in heart and breathing rate is due to less oxygen available for the cells. This condition is known as hypoxia caused by insufficient blood hemoglobin to supply oxygen for physical activities at higher altitudes.

Answer:

Particle A is negatively charged.

Particle B is neutral.

Particle C is positively charged.

Explanation:

Particle A is negatively charged because the number of electrons is more than number of protons so the particle gain negative charge. Particle A is neutral due to same number of proton and electron which cancels the effect of one another and become neutral whereas the Particle B is positively charged due presence of more number of protons as compared to number of electrons so the particle gain positive charge.

Explanation:

A fossil record is a group of fossils which has been analyzed and arranged chronologically and in taxonomic order. Fossils are created when organisms die, are incased in dirt and rock, and are slowly replaced by minerals over time. What is left is a mineral impression of an animal which once existed. Many fields and specialties are utilized to categorize and arrange these fossils, including comparative anatomy, radiometric dating, and DNA analysis. Using the data from the fossil record, scientist try to recreate phylogenies, or trees describing the relationships between animals, both alive and extinct. The fossil record helps inform how different groups of animals are related through evolution.

Answer:

Fossils are the geologically altered remains of a once-living organism and/or its behaviour. There are two main types: body fossils represent all or part of the organism’s body, and trace fossils show evidence of the organism’s behaviour. The study of fossils is called paleontology, from the Greek meaning ‘ancient (paleo-) being (onto-) study (-logy)’. Scientists who study fossils are called paleontologists. Fossils are of particular interest to geologists as they can help determine the age of a particular rock compared to other rocks, or identify the environment in which the rock was formed.

Answer:

C. A perfect, mutation-free society

Explanation:

Mutation is a genetic phenomenon involving the alteration or change in the genetic sequence of a gene. Mutation is commonly caused by mutagens (chemical substances that induce mutation), DNA replication mistakes or errors etc.

According to this question, if DNA replication occurs without error, this means that mutation will likely not occur, leading to a perfect, mutation-free society.

Answer:

The correct answer is - stomach.

Explanation:

The stomach is the only part of the digestive tract among the duodenum, large intestine, stomach, and esophagus that has three layers of smooth muscle.

The duodenum, large intestine, and esophagus simple columnar epithelium, and others have two -layers of smooth muscles and have simple columnar epithelium. This suggests that the mucosa is the section of the stomach in the digestive tract

Answer:

as humans population continues to grow, we're cutting down more trees and occupying more lands to suffice the need of citizens, therefore, decreasing the forest biodiversity. Our plastic bags, as well as wastes, are polluting the ocean and eradicating essential species that are required to sustain a balance ecosystem, therefore, decreasing the biodiversity of the ocean that are required to maintain a balance environment.

Human activities have affected in Biodiversity in the ecosystems negatively  and such activities include : i) Indiscriminate hunting/fishing  ii) Improper waste disposal

Humans in search of food ( meat ) engage in excessive/indiscriminate hunting of endangered species thereby reducing the Biodiversity of animal species present in the wildlife also excessive fishing activities affects the biodiversity of certain species of fishes in our oceans negatively.

When wastes are not properly disposed they degrade the environment and decrease the biodiversity of the ecosystems in the process. the burning of industrial wastes leads to the exposure of certain species to the negative effects of dangerous gases and liquids thereby making the ecosystems to become unbalanced.

Hence we can conclude that some of the human activities impacting biodiversity in ecosystems around the world include : Indiscriminate hunting/fishing  and Improper waste disposal

Answer:

Both hawk and owl share the same habitat or ecosystem.

Explanation:

According to competitive exclusion principle, two species can't coexist in the same environment if they occupy exactly the same niche but in the case of hawk and owl, it is possible because both have different times of eating habits. Hawks hunts at daytime while on the other hand, an owl hunts at night so both share the same habitat due to difference in their niche and they are present in the same ecosystem.

penicillin was the first antibiotic discovered. Alexander Fleming discovered it in 1928. It was used widely during World War II. However, the sulfonamides were the first antibiotic class used clinically (in the 1930's). The discovery of antibiotics revolutionized medicine by making once-deadly infections treatable. There are now hundreds of antibiotics, classified into several categories. These antibiotic classes include:
