Critical thinking : Do magnets need to touch a piece of iron or another magnet to exert a magnetic force on the iron or other magnet?

Answers

Answer 1

Answer:

I wouldn't think so because it is the magnetic field that Attracts and repels. When iron is magnetised to something don't the molecules lineup in the North the South pattern or something like that to create a magnetic field and stick together.

I might be wrong because this is my personal opinion on the matter.

Answer 2

Answer:

no because the magnetic force attracts the magnet or the iron to it

What happens when the nucleotides in a DNA synthesis reaction are radioactive?

Answers

If a cell is grown in a medium containing radioactively labeled thymidine--which is one of the nucleotides needed to synthesize DNA--after the first round of replication, all of the DNA molecules will have one labeled strand and one unlabeled strand. Why? Because the radioactively labeled thymidine will be incorporated into the newly synthesized strands. If the cell undergoes ANOTHER round of replication in the same medium, the same sequence of events will occur.

B. Robins and sparrows have different types of bases.
C. Robins and sparrows have different arrangements of the bases.
D. Robins and sparrows have the same arrangement of the bases.

Answers

Answer: the answer is C —> AP.EX

Explanation:

The nucleotide bases are the nitrogenous rings that form the backbone of the nucleic acid. Robins and sparrows have the same bases with different arrangements. Thus, option C is correct.

What are nucleotide bases?

The nucleotide bases or the nucleobases are the fundamental units that together with the sugar molecule and phosphate make the structure of the DNA or RNA.

There is a total of five nucleotide bases divided into purines and pyrimidines based on their ring structures. The purine consists of adenine and guanine, pyrimidine of cytosine, uracil, and thymine.

The bases are universal in organism containing the DNA or RNA but only differs in their arrangements that result in the development of the various traits and characteristics of the organism.

Therefore, in option C. the bases are arranged differently in species.

which of the following correctly describes the induced fit process of how enzymes work

1.the substrate binds and the enzyme split apart prior to actiong on the substrate

2. the substrate binds and the substrate changes changes shape and then substrate is acted upon by the enzyme

3. the substrate binds and is immediatelyacted upon by the enzyme

4. the substrate binds and the enzymes changes shape and then the substrate is acted upon by the enzyme ​

Answers

Answer:

The correct answer would be number 2

Explanation:

The correct description of the induced fit process of how enzymes work is;

The substrate binds and the substrate changes shape and then substrate is acted upon by the enzyme ( 2 )

In an Ideal fit model for catalysis, the substrate will bind to a site ( active ) and the substrate bond to the site will change its shape before been acted upon by the enzyme to form a complex ( enzyme- substrate ).

The enzymes ( biological catalyst )does not change shape permanently during the reaction process but it returns to its original shape after the reaction ( end of reaction )

Hence we can conclude that correct description is the substrate binds and the substrate changes shape and then substrate is acted upon by the enzyme.

What are biogeochemical cycles?

They are the connection and movements that exist between living elements (biotic factors) and non-living elements (abiotic factors) in order for energy to flow.

Characteristics of biogeochemical cycles

It is the exchange of chemical elements between living beings and the environment that surrounds them

They involve both the different forms of life (plant, animal, microscopic, etc.), as well as inorganic natural elements and compounds (rain, wind, etc.)

Therefore, we can conclude that biogeochemical cycles deal with a perpetual displacement of matter from one place to another and two parts or compartments can be recognized: the biotic and the abiotic.

People who have Tay-Sachs disease cannot metabolize some lipids effectively. Tay-Sachs is a recessive disorder. A student used a Punnet Square to determine the probability of offspring inheriting the disease. The results from a Punnet Square are 25% TT, 50% Tt, and 25% tt.

Which conclusion can be made regarding the phenotype of the parents based on these results?

The parents must be TT, Tt

The parents must be Tt, tt

The parents must be TT, tt

The parents must be Tt, Tt

Answers

Answer:

The parents must be Tt, Tt

Explanation:

Based on these results, we can conclude that each of the parents will have one dominant (T) and one recessive allele (t). We can prove this by drawing the Punnett square:

     T      t

T    TT   Tt

t     Tt     tt

We can see that the offspring will have the Tt genotype in two cases, the TT genotype in one case, and the tt genotype in one case, as well. Now we need to do some basic math. Two out of four is 50% (Tt - 50%), and one out of four is 25% (TT - 25%, tt - 25%).

This means that the parents must be Tt, Tt.

PLATO GANG

The IQ range that indicates moderate mental *********** is A. 70-79.

What is an IQ?

IQ stands for Intelligence Quotient and is a measure of cognitive abilities and intellectual potential. It is determined through standardized tests that assess various cognitive skills, including problem-solving, memory, and analytical thinking.

The average IQ score is set at 100, with scores ranging from 70 to 130 considered to be within the normal range. Scores below 70 indicate varying degrees of intellectual disability, while scores above 130 suggest above-average intelligence.

While IQ scores can provide insight into a person's cognitive abilities, they do not account for other factors, such as emotional intelligence or creativity, that may contribute to overall success in life. It is essential to recognize that IQ tests have limitations and should not be used to label individuals or limit their potential.

This range is considered to be a mild to moderate intellectual disability, indicating limitations in adaptive functioning and potential need for support in daily life activities.
