5.In the event of a mismatched nucleotide , which molecule is able to backtrack , "proofread ," and correct the nucleotide sequence? A.DNA Proofreadase B.DNA Polymerase C.DNA Helicase D.DNA Primase
Answer:
1) Transcription Bubble.
2) Replication Forks
3)
Explanation:
1) The region of opened- up DNA is called a Transcription Bubble. In transcription, a region of DNA opens up. One strand, the template strand, serves as a template for synthesis of a complentary RNA transcript.
2) The Replication Forks hold the 2 separated strands of DNA apart, preventing then from assuming their double helix shape... in order to replicate all your DNA its faster to replicate DNA if your doing it in many different areas at the same.
3)Since DNA polymerase requires a free 3` OH group for initiation of synthesis, it can synthesize in only one direction by extending the 3` end of the preexisting nucleotide chain. Hence, DNA polymerase moves along the template strand in a 3`-5` direction, and the daughter strand is formed in a 5`-3` direction.

The answers to the following questions are:
Replication bubble.Replication fork One moves towards from the replication fork and the other moves away from it..Each copy is identical to each otherDNA PolymeraseWhat is DNA replication?A double-stranded DNA molecule is copied to create two identical DNA molecules through the process of DNA replication. Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.
A particular kind of enzyme called DNA polymerase (DNAP) is in charge of creating fresh nucleic acid molecules that are copies of the original DNA. Polymers are huge compounds consisting of smaller, repeating units that are chemically linked to one another. Nucleic acids are polymers.

Why don't we all look the same if all humans have the same number of chromosomes
that contain the same genes?
Answer:
A small number of genes are slightly different in everyone which results in everyone looking different from one another. Each person has two copies of each gene, one from your mother and father which makes you look somewhat alike. Their are alleles that have small differences in them which are different from someone elses DNA bases which make you look different.

Pea plant clones are given different amounts of water for a three-week period. First pea plant receives 400ml. Second pea plant receives 200ml. Third pea plant receives 100ml. Fourth pea plant does not receive any extra water; the plant only receives natural ways of receiving water. The height of the pea plants is recorded daily. What is the independent variable?
A) the different amounts of water
B) the heights of the pea plant
C) the pea plants
D) the natural ways of receiving water
Answer: The independent variable is the different amount of water. The correct option is A.
Explanation:
A variable can represent age, a person, or an entity that can be measured. In statistics, it is simply defined as an attribute of an object to be investigated. There are different types of variables these includes:
--> Dependent variable and
--> Independent variable.
Dependent variables are simply the variables that are affected by the changes that occurs in the experiment. From the experiment they should include:
--> the height of the plant,
--> the size of the plant,
--> the number of leaves
---> if the plant survived or not (dead).
Independent variable are the variables that are changed in the experiment. A good example from the pea plant experiment is WATER. It is the aspect that is used to alter the dependent variable which is the height of the pea plant. I hope this helps, thanks!

How many more cherry pies have 60 to 89 cherries than 90 to 119 cherries?
Answer:
They are the same thing
6 pies are more in 60 to 89 cherries than 90 to 119 cherries, a bar graph is a graphical depiction of information, amounts, or numbers using bars or strips.
How to depict the bar graph?They are employed to contrast and compare various data kinds, frequencies, or other measurements of several categories of data.
The calculation of the bar graph in the given question.
For 60 - 89 cherries there are 10 pies
For 90 -119 cherries there are 4 pies
10 -4 = 6 pies
The image for the graph is attached below.
When displaying sections of data, bar charts should be used. As long as there aren't too many categories to compare, vertical bar charts can be useful for comparing several categories or discrete data, such as age groups, classes, schools, etc. They are quite helpful for time series data as well.
Therefore, there are 6 more pies in the 60 -89 cherries category than in the 90-119 category.

light enters a plant through its leaves O2 enters the plant through the stomata's or open pores
and water enters through the roots then up the stem to the tubes to leave
Explanation:
hopefully this helps
The Plants able to obtain each ingredients from the atmosphere. the light from the sunlight, [tex]CO2[/tex] from the stomata, and the water from the roots.
Stomata allow plants to absorb [tex]CO2[/tex] from the atmosphere. Water is taken from the earth by plants and transmitted to their leaves via their roots. The only source of light that the chlorophyll and other green parts of the plant absorb is sunlight.
Plants use sunlight, water, and carbon dioxide to perform photosynthesis.
They produce Chlorophyll, the pigment that makes plants green, by using stored carbon, hydrogen from water, and magnesium from the soil. They make Adenosine triphosphate, which is vital in energy transfer, by combining phosphorus, oxygen, and carbon.
Thus, Plants take nutrient from the atmosphere . light from the sunlight, [tex]CO2[/tex] from the stomata, and the water from the roots.

Which would have most likely stopped Mendel from finding a pattern in his
results?
A. If having a wrinkled seed had been a recessive trait
B. If garden peas had used sperm and egg to reproduce
C. Being short is a recessive trait
D. If seed color and shape were located on the same chromosome
Answer:
D. If seed color and shape were located on the same chromosome
Explanation:
If seed color and shape were located on the same chromosome, they would not be inherited independently of one another.
Genes on the same chromosome are more likely to be inherited together. The only way they could be inherited independently is if crossing over occurred between the two genes.
Therefore, this would argue against Mendel's law of independent assortment.

For the initial year of a summer camp, 56 girls and 64 boys enrolled. Each year thereafter, 18 more students enrolled in the camp. Let t be the time (in years) since the camp opened. Part A: Write a function rule for the total number of students enrolled t years after the camp opened.
Answer:
[tex]f(t)=120+18t[/tex]
Explanation:
We know that for the initial year of a summer camp, 56 girls and 64 boys enrolled.
The total children enrolled for the initial year can be calculated as :
[tex]56+64=120[/tex]
Each year, 18 more students enrolled in the camp.
The variable ''[tex]t[/tex]'' represents the time in years since the camp opened.
The following expression :
[tex]18t[/tex]
represents the extra children enrolled each year
If we sum, we can obtain the following expression :
[tex]120+18t[/tex]
which is the function [tex]f(t)[/tex] for the total number of students enrolled [tex]t[/tex] years after the camp opened.
The function rule is [tex]f(t)=120+18t[/tex]
For example, when [tex]t=0[/tex] ⇒
[tex]f(0)=120+18(0)=120[/tex]
which is the original amount of enrolled children when the summer camp opened.
When [tex]t=3[/tex] ⇒
[tex]f(3)=120+18(3)=174[/tex]
which is the expected value for the total number of students enrolled 3 years after the camp opened.

Cual de estos no se podria observar en un microscopio optico crestas mitocondriales, poros de la membrana nuclear, cromosomas de una celula animal condensados durante la mitosis, las dos capas lipidas que forman la membrana plasmatica
Answer:
Crestas mitocondriales, poros de la membrana nuclear y las capas lipídicas que forman la membrana plasmática no son visibles al microscopio óptico.
Explanation:
El límite de resolución de un microscopio óptico es de, aproximadamente, de 0,2 μm (es decir 10⁻⁶ m). Es decir, que en un microscopio óptico sólo podrán verse células y estructuras celulares mayores a 0,2 μm, y en algunos casos serán visibles sólo con tinciones especiales.
Por ende, entre las cuatro estructuras que se nos presentan en el problema sólo los cromosomas de una celula animal condensados durante la mitosis pueden verse al microscopio óptico.
Tanto las crestas mitocondriales como los poros de la membrana nuclear y las capas lipídicas que forman la membrana son estructuras muy pequeñas y visibles solamente al microscopio electrónico.
