You are a genetic counselor. A couple comes to you for advice. The female is eight weeks pregnant with their first child. Both are Ashkenazi Jews, a segment of the population in which Gaucher disease is relatively common. Gaucher disease is a condition that can range from mild and treatable symptoms to severe, debilitating problems. The disease is an autosomal recessive pattern. Which of the following statements is true?
The child will likely have Gaucher disease if she has inherited recessive alleles from each parent.
The child will likely have Gaucher disease if she has inherited one dominant allele from her father.
The child will only have Gaucher disease if she has inherited both dominant alleles from her parents.
The child will only have Gaucher disease if she has received one recessive allele from her mother.

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.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.

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.
hope this helps
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.

Answer:
Glycolysis occurs in the Cytoplasm
Electron Transport Chain occurs in the Mitchondria
Krebs Cycle also occurs in the mitchondria
Explanation:
Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. Nearly all living organisms carry out glycolysis as part of their metabolism. The process does not use oxygen and is therefore anaerobic. Glycolysis takes place in the cytoplasm of both prokaryotic and eukaryotic cells.
The electron transport chain is the last stage of the respiration pathway. It is the stage that produces the most ATP molecules. The electron transport chain is a collection of carrier proteins found on the inner membrane of mitochondria. NADH hydrogen ions and electrons into the transport chain.
The Krebs cycle happens only within the mitochondrial matrix. Pyruvate is formed in the cytosol of the cell, then imported into the mitochondria.

how does the operator region of dna work to regulate gene expression?.
Answer:The promoter is found in the DNA of the operon, upstream of (before) the genes. ... Some regulatory proteins are repressors that bind to pieces of DNA called operators. When bound to its operator, a repressor reduces transcription (e.g., by blocking RNA polymerase from moving forward on the DNA).
