Some scientists have suggested that the Protista kingdom should be split into several groups instead of remaining as one group. Which of the following provides the best argument for dividing up the Protista?

1: Sporozoan Protista are more similar to the Fungi than they are to any of the other groups of Protista.

2: Colonial Protista have much more in common with other multicellular organisms than they do with unicellular Protista.

3: The Protista that have nuclei are significantly different from the rest of the Protista that lack a nucleus.

4: Protista do not have specialized cells and have varying methods to obtain their food.

Answers

Answer:

Number 4 is correct

Explanation:

I took the test and got it right

Protista do not have specialized cells and have varying methods to obtain their food. Thus, Option D is correct.

what are major  characteristic features of Protista ?

Protists are simple ancient unicellular eukaryotic organisms. They are neither plant nor animal and fungi, mostly live in water, on substrate, as parasite etc.

Some multicellular protists are also found such as kelp.

It has nucleus and membrane-bound organelles, autotrophic or heterotrophic depending on mode of nutrition.

A phenomenon called symbiosis is observed in this kingdom

Some protists show parasitism, for example Trypanosoma protozoa causative agent of sleeping sickness in humans.

Two locomotory organs cilia and flagella nd also pseudopodia are observed in  kingdom, aerobic mode of respiration occur.

Both sexual reproduction or syngamy and asexual reproduction occur. They are classified into protozoa or animal like, fungus like, and plant-like.

Thus, Option D is correct.

Hemophilia is a disease that causes uncontrollable bleeding. If a father has it, all of his daughters will be carriers of the disease, and about half of his sons will have the disease.

Which macromolecule is involved in how hemophilia is passed from parents to their children?

Answers

Explanation:

Hemophilia is a disease that is characterized by an abnormal blood clotting process. There are many different proteins that are involved in the clotting process and a single mutation or change in one of them could result in serious effects. Hemophilia is characterized by an abnormal version of one of the many proteins involved in the clotting process, the proteins that are commonly affected are the coagulation factor 8 or 9 (VIII or IX). These abnormal proteins are caused by a mutation in the gene (within the DNA) that codifies for the production of each protein. In other words, a mutation in the part of the DNA, (gene F8) will lead to a dysfunctional coagulation factor VIII and a mutation in the gene F9 will lead to a dysfunctional coagulation factor IX. Importantly, these mutations could be inherited and could cause hemophilia. Therefore, an error in the DNA and subsequently, an error in the protein will cause hemophilia. Finally, it is important to mention that there are other types of hemophilia that are not caused by the above-mentioned mutations, such as acquired hemophilia.

Answer:the macromolecule which is involved in haemophilia which is passed from the parents to the children is the defect in factor number 8 of clotting cascade.

Define the absorbance value displayed on the spectrophotometer.

Answers

Absorbance is the measure of the quantity of light intensity absorbed by a sample solution.

What is absorbance?

Absorbance, denoted by A, is used to measure the amount of light intensity that is absorbed by a sample.

Absorbance is measured in a technique called spectrophotometry using a device called spectrophotometer. The spectrophotometer measures the intensity of light as photons of light passes through the sample.

The amount of that incident light that is absorbed by the sample is then displayed on the screen or output of the spectrophotometer.

You suspect that a newly discovered cell is undergoing photosynthesis. You add water and carbon dioxide to the cell and expose it to sunlight. What should be produced in the cell if photosynthesis is occurring

Answers

Given what we know, if the newly discovered cell is undergoing photosynthesis, it should produce sugar molecules and oxygen.

Why should we expect these substances?

As with any cell that undergoes photosynthesis, the cells require some substances as the prerequisites and then expel others as the products. For photosynthesis, these substrates required are carbon dioxide and sunlight, as a result, they then produce sugar molecules as the final result, and release oxygen as a by-product.

Therefore, we can confirm that if the newly discovered cell is undergoing photosynthesis, it should produce sugar molecules and oxygen.

If the base sequence on a DNA molecule is ATC, what would be the mRNA codon sequence?

Answers

The mRNA codon would be UAG because it flips: A-T, C-G and then replaces thymine (T) with uracil (U)

If the base sequence on a DNA molecule is ATC then UAG will be the mRNA sequence.

How many mRNA codons are there?

The four nucleotides found in mRNA — A, U, G, and C — can be combined in a total of 64 different ways because codons are three-letter structures. These 64 codons are made up of 61 amino acid codons and three stop signal codons, which signal the completion of protein synthesis.

A codon is a specific sequence of nucleotides on an mRNA that denotes either a stop signal during protein translation or a specific amino acid. A nucleobase (also known as base), a sugar, and a phosphate group make up a nucleotide.
