What process is typical of cancer?
A)replacement of damaged cells
B)DNA replication
C)cellular death
D)uncontrolled cell division
Answer:
D: uncontrolled cell division
Explanation:
The cells start dividing rapidly and created masses, or tumors, which is called cancer
Uncontrolled cell division is the process typical of cancer.
What is cancer?It is a condition in which cells begin to divide uncontrollably.
What are the types of cancer?There are generally two types of cancer:
Benign: grow slowly and not spread.Malignant: have the ability to spread throughout the body, grow quickly, infiltrate neighboring normal tissues, and do great damage.What is contact inhibition?Contact inhibition is the process whereby a normal cell's unchecked proliferation is inhibited as a result of its contact with neighboring cells.
What happens when contact inhibition is lost?When this property is lost the cells undergo uncontrolled division and they form cancerous growth.

In this lab, you will simulate birds with three different beaks. After watching the birds feed, you will remove fruit to simulate a change in the environment. What question are you answering by doing this observation?
Answer:
How does a change in food resources model the type of beaks in birds?
Explanation:
We know that phenotype results from the interaction of the genotype and the environment. Any change in the environment produces a change in the phenotype of the animals. By performing this experiment, we probably want to know the influence of the environment on animals. In this particular example, we change a source of food by removing fruit (which would be acting as the independent variable of the experiment) and evaluate its effects on the birds´ beak (the dependent variable). Which of the three different beaks increases their frequencies by removing the fruit, and which one decreases its frequency.
So here, the absence of fruit is acting as a selective ecological pressure on birds. It is modeling birds´ beaks and adapting animals to feed on some other resource.
Change in food resources ---> Selective ecological pressure.Change in beaks frequency----> Adaptative response.The image on the left shows a normal red blood cell, and the image on the right shows a cell that has been put into a new solution. The circles represent the salt in the solutions.

Given RRYY x Rryy, what will the parents be? (no links please)
I'm guessing the genotypes given (RRYY x Rryy) are the offspring (if this isn't the case this answer may be wrong)
RRYY has both dominant alleles. So we can safely say that the parents are both RRYY.
For Rryy :
Rr is heterozygous (the alleles are not the same), so the parents could be:
RR x rr
RR x Rr
Rr x Rr
(if you do a small punnet square, you can double check these!)
Since yy has both recessive alleles, the parent is yy as well.

Explain how the oxidation of pyruvate links glycolysis with the citric acid cycle.
Pyruvate oxidation is the step that connects glycolysis to the citric acid cycle through the generation of acetyl-CoA.
The first thing that happens after glycolysis is that pyruvic acid passes from the cytoplasm to the mitochondrial matrix, crossing the membranes.
Pyruvic acid undergoes oxidation, a CO2 molecule is released and an acyl group (CH3-CO) is formed.
In this reaction, one molecule of NADH is formed, as in glycolysis the final product was two molecules of pyruvic acid, now two of NADH will be formed for each molecule of glucose.
Each acyl group binds to a Coenzyme A and acetyl Coenzyme A is formed, at this time the citric acid cycle begins.
Acetyl-CoA is degraded in the citric acid cycle to produce energy when cellular needs demand it.
Therefore, we can conclude that glycolysis achieves from the degradation of glucose to obtain 2 molecules of pyruvate, which is a previous step to give acetyl-Coa, which is the starting molecule of the citric acid cycle.

Si se aplica a un muelle una fuerza de 30N provocamos que se alarguen 0.2m . Calcular la constante del resorte. Y que fuerza que habra que aplicarle para que se alargue 0.45m
Answer:
I. Constante de resorte, k = 150 Nm.
II. Fuerza = 67.5 Newton.
Explanation:
Dados los siguientes datos;
Fuerza, F = 30 N
Extensión, e = 0.2 m
Para encontrar la constante del resorte;
Fuerza = constante de resorte * extensión
F = ke
30 = k * 0.2
Constante de resorte, k = 30 / 0.2
Constante de resorte, k = 150 Nm
A continuación, para encontrar la fuerza para una extensión de 0,45 m;
Fuerza = 150 * 0.45
Fuerza = 67.5 Newton.

The diagram below shows part of the process of DNA transcription. Which
mRNA base will go in location 3
DNA
TGTGTGAL
ACACAC123
-
mRNA
O A. Cytosine
OB. Thymine
O C. Uracil
D. Adenine
SUBMIT
Answer: The correct answer is D. Adenine
Explanation:
There are two types of nucleic acid ribonucleic aid and deoxyribonucleic acid. There are four types of nucleotides which make the DNA and these are adenine, guanine, thymine, and cytosine.
Adenine and thymine make complementary base pairing with each other and guanine and cytosine make complementary base pairing with each other in DNA.
In RNA against adenine, uracil comes and against thymine adenine comes. Therefore as at location 2 thymine is present in DNA so in RNA against it adenine will come.

In DNA transcription, Adenine mRNA base will go in location 3 DNA. Therefore, option (D) is correct.
What do you mean by DNA transcription?The process by which information in a DNA strand is copied into a new molecule of messenger RNA (mRNA) is known as transcription. DNA safely and stably stores genetic material as a reference, or template, in the nuclei of cells.
Because it is the primary point at which the cell regulates which proteins are to be produced and at what rate, the initiation of transcription is an especially important step in gene expression.
The process by which RNA polymerase rewrites the genetic information in DNA into messenger RNA (mRNA) is known as DNA transcription. This mRNA then, at that point, leaves the core, where it goes about as the reason for the interpretation of DNA.

A small baby snake grows into a larger adult snake. Choose the explanation that best explains why a baby snake grows into a larger adult snake.
A. The baby snake’s cells divide.
B. The baby snake’s cells grow into longer cells.
C. The baby snake’s cells grow into much larger cells.
D.The baby snake’s body parts stretch out and get longer.
E.The food the baby snake eats makes it grow big and strong.
F.The baby snake’s cells differentiate into different types of cells.
Answer:
A. The baby snake's cells divide.
Explanation:
Just like all multicellular organisms, the snake grows through its cells growing and then dividing into more cells.
The baby snake grows into an adult one because of cell division; the option A that is saying this is the correct regarding the growth of the snake into the big snake
What is the result of the cell division?Cell division is the process by which the cell divides into either haploid or genetically identical cells. The snake grows in size because of cell division.
This is the result of the mitosis, in which the parent cell present in the small snake divides to produce many cells, and the increase is seen. In mitosis, the cell enters the prophase, metaphase, anaphase, and telophase, and finally, at cytokinesis, the cell divides into two.
In the interphase of the cell cycle, before the cell division phase, the cell duplicates its genetic material. The cell differentiation does not increase the cell number, but the cell division increases the cell number and makes the snake grow bigger.
Hence, the correct answer is "baby snake cells divide," which is in Option A.
