Strawberry jelly is a very strong solution of sugar. By contrast the cytoplasm in bacteria is a much weaker solution. The cell wall of bacteria is made up of a PARTIALLY permeable membrane. Would water flow from the microbe to the jam, or from the jam to the microbe by osmosis? Explain​

Answers

Since the concentration of the jelly is higher than the concentration of the bacterial cytoplasm, water would flow from the microbe to the jam by osmosis.

What is Osmosis?

Osmosis is the movement of water molecules from a region of low solute concentration to a region of high solute concentration through a semi-permeable membrane.

The strawberry jelly is a stronger solution than the bacterial cytoplasm.

Therefore,  water would flow from the microbe to the jam by osmosis.

If you were analyzing a microscopic model of a freshwater ecosystem, one autotroph that you might encounter is an alga. Thus, the correct option for this question is B.

What is an Ecosystem?

An ecosystem may be defined as a type of place or an area where individuals of different species live together and interact with one another for the purpose of food, shelter, and space.

According to the context of this question, algae are generally found in the freshwater ecosystem as well. They significantly utilize the nutrients from other water bodies and grow appropriately. While organisms like ciliates, bacteria, and flagellates are found in polluted or salty/marine water.

Therefore, if you were analyzing a microscopic model of a freshwater ecosystem, one autotroph that you might encounter is an alga. Thus, the correct option for this question is B.

In 1978, scientists studied how the fitness of marine sticklebacks would be affected if they were introduced into a freshwater environment. They collected 90 male and 90 female sticklebacks from a marine population and 10 male and 10 female sticklebacks from a freshwater population. The 200 sticklebacks were introduced into a freshwater environment that had no stickleback fish previously.

Recently a scientist decided to repeat this study, but relocated a population of sticklebacks from a freshwater environment into a marine environment. Which of the following best predicts how the frequency of the allele would change over time if a population of sticklebacks from a freshwater environment was placed into a marine environment?

Answers

The frequency of alleles in the population started low and continued to increase over time.

What is frequency of alleles?

The frequency of alleles refers to the ratio of the number of times an allele occurs to the copies of all the alleles at that particular genetic locus  in the given population.

We can see that the sticklebacks had a greater number of those introduced from marine to fresh water hence of the 200 sticklebacks, the frequency of alleles in the population started low and continued to increase over time.

Why are start and end amino acids encoded by only one codon?

Answers

Answer:

The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid. Since there are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases).

Nonspecific is the innate immune response that is present since birth. White blood cells and mast cells are examples of non-specific immunity.

What is a nonspecific immune response?

The non-specific immune response is the immunity present in the child from his/her birth and is a generalized response that employs white blood cells and mast cells for conferring the pathogens.

It is innate immunity that protects from the invasion of pathogens and provides the first line of defence by forming barriers.

It includes the invasion of the white blood cells in the area of any cut or injury or the release of the histamine from the mast cells in an injured area for the inflammation pathway.

Therefore, the statement I about white cells and II about mast cells are examples of the non-specific immune response.
