Answer:
The correct answer is - 6 chromatids.
Explanation:
Prophase is the stage in the cell cycle that is known for the condensation and disappearance of the nucleolus. In this stage chromosome become more compacts and the sister chromatids are still together and not separated. These sister chromatids are joined together with the centromere.
Centromere do not allow sister chromatids to move away and makes it intact. The number of centromere is the number of chromosme present in the prophase and half of the sister chromatids that means if there us 3 centromere than the number of sister chromatids will be 6.

Explanation:
Use your codon chart and tell me what amino acids are coded for by the mRNA sequence AUG CGG UCC GGA
Answer:
Methionine, arginine, serine, glycine
Explanation:
Use a codon chart (attached below) to determine what amino acids are coded for by the strand of mRNA. Remember that codons are groups of three nucleotides in mRNA. So, read the nucleotides in groups of three (just as how they are separated by spaces) and from left to right.
To use this codon chart, identify the first letter representing the first nucleotide in the codon. Then, find the matching letter that's one of the four biggest letters in the middle of the chart. Identify the second letter, then find the matching medium letter in the chart, staying within the section of the first letter as indicated by the lines, and do the same process with the third. Repeat for each codon.
Thus, with this mRNA strand, the amino acids will be methionine, arginine, serine, glycine.

Which of the following will most likely decrease genetic diversity?
А increased reproduction
B selective breeding
C mutations
D immigration
Selective breeding dangers reduced genetic diversity can result in certain insects or diseases attacking, which could be quite devastating. Thus, option B is correct.
What is the cause of selective breeding in genetic diversity?Selective breeding can contribute to a large reduction in the genetic diversity of farmed populations, endangering long-term evolutionary progress and limiting populations' ability to adjust to environmental changes.
Unknowingly selecting uncommon illness genes as part of a desirable characteristic might cause difficulties with particular organisms, such as the high prevalence of deafness in Dalmatian dogs.
Genetic diversity is typically reduced by selective breeding, since only a few individuals are employed to produce enormous numbers of offspring. The population's survivability may be impacted by this.
Therefore, selective breeding will most likely decrease genetic diversity.

Explain the strengths and weaknesses of Lamarck's theory of evolution.
There is no experimental proof of the lamarckism. New organs are not formed in organisms by their wish or requirement. 3.It is not necessary that an the acquired characters transmit into new
Answer:
Weaknesses are traits may stay around for longer that what their needed and Strengths are we adapt to our needs.
Explanation:
Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.

Why would it not make sense for the cell to wait to combine Okazaki fragments into one continuous lagging strand until the entire DNA molecule has been replicated
Answer:
Okazaki fragments are short DNA nucleotides sequences that are formed discontinuously and then combine into one continuous lagging strand with the help of DNA ligase, the endonuclease, and polymerase. It takes place before the entire DNA molecule has been replicated.
If the cell waited to combine Okazaki fragments until the entire DNA molecule had been replicated then the newly synthesized lagging strand that are still Okazaki fragments might already be packaged and inaccessible to the all essential enzymes that are ligase, polymerase, and endonuclease that help to generate a continuous leading strand.
Which statements explain the cold temperatures in the Northern Hemisphere during the winter? Choose the TWO correct answers.
A.
The Northern Hemisphere is farther from the sun during the winter.
B.
In the Northern Hemisphere, the sun is lower in the sky during the winter.
C.
Earth is farther from the sun during the winter.
D.
Earth rotates more slowly during the winter.
E.
The Northern Hemisphere gets less direct sunlight during the winter.
Answer: Option A and E.
Explanation:
Norther hemisphere Is the half of the Earth that lies on the north of the equator. The equator is the line that divide the Earth into two halves.
During the winter, the northern hemisphere is colder because the northern hemisphere move away from the sun and receive less sunlight form the sun. The sun is very high in temperature and it has high heat, when the northern hemisphere move away from it, there is lower heat or temperature that get to it , making it to become cooler or have lower temperature. The countries in the northern hemisphere comprises of all countries in Europe, North America, Asia,part of South America and little part of Africa.

What is an observational study? How is it different from a controlled experiment?
Answer:
Observational study is when you observe your subject and take more notes rather that writing down quantitative data. Meanwhile, a controlled experiment is more quantitative.
Explanation:
This model shows the process of protein synthesis including transcription and translation. What is the best explanation for what is
occurring at the arrow (translation)?
Answer: The answer is C
Explanation:
During the process of protein synthesis, the best explanation for what is occurring at the arrow is as follows:
The codon on the mRNA pairs with the anticodon on the tRNA which transfers amino acids into the proper sequence to form a protein.What is Protein synthesis?Protein synthesis may be defined as a biological process through which cells make proteins in order to accomplish metabolic functions that facilitate the survival of living organisms. The process of protein synthesis terminates with the help of two stages. They are as follows:
Transcription.Translation.Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. While the process of translation acquired the transfer of genetic instructions from the mRNA to the sequence of amino acids in order to form proteins. This takes place in the cytoplasm of the cell.

What percentage of offspring would be deaf?
25%
50%
75%
100%
Answer:
3/4 (3 out of 4) of the genotypes are deaf. 3/4 is also equal to 75%. So 75% of the offspring produced will be deaf.
Explanation:
The way the punnet squares work is the top allele on the left combines with the left allele on the top, the top allele on the left is combined with the top allele on the right, the bottom allele on the left is combined with the top allele on the left, the bottom allele on the left is combined with the top allele on the right.

what is the molarity
Answer:
Hope its help you
if wrong then sry
Answer:
Explanation:
the number of moles of solute per liter of solution. molar concentration
Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per liters of a solution. Molarity is also known as the molar concentration of a solution. Explanation: To get the molarity, you divide the moles of solute by the liters of solution. Molarity=moles of solute liters of solution. For example, a 0.25 mol/L NaOH solution contains 0.25 mol of sodium hydroxide in every litre of solution.

Explain the difference between independent variables, dependent variables, and control variables.
Answer:
Independent: Purposely altered
Dependent: Changes with respect to the independent being altered
Controlled: Never changes
Explanation:
An independent variable is a variable in which does not rely on other pieces/variables of an experiment to assume a value. In other words, it does not change when other variables change. However, it can be changed intentionally by the scientist.
A dependent variable is a variable in which its change in value relies on other pieces/variables of an experiment to assume a value. So, if the indeoendent variable is changed, the dependent variable will change as well. The opposite is not true though - if the dependent variable changes (for whatever reason), the independent variable hasn't necessarily been changed.
A controlled variable is a variable that stays CONSTANT throughout an experiment. It is never changed, and nothing will change it. An example of a control variable is the number of participants in a study: no more participants are being added, and no participants are being removed. The number of participants remains STATIC throughout the study.
