According to Watson and Crick, DNA replication used each strand's nucleotides as a template for new strands. Thus,option A, D, H is correct.
What is the Watson and Crick model about DNA?Watson-Crick DNA structure. The molecule of DNA is a double-stranded, helical structure. It consists of two sugar-phosphate backbones on the outside and nitrogenous base pairs on the inside, bound together by hydrogen bonds.
DNA behaves like a double helix made up of two protracted, intertwined helical strands.
In their model, the bases along one DNA strand matched the bases along the other DNA strand. Each DNA strand comprised discrete units known as bases.
Therefore, Watson and Crick built and proposed the DNA structure, which determined important features of DNA.

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.

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.

What is the sugar found in DNA that makes up the sugar-phosphate backbone of the double helix?
Answer:
deoxyribose
Explanation:
A phosphate backbone is the portion of the DNA double helix that provides structural support to the molecule. DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups.

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).

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.We added 30 N of force to the right side of the box. What is the net force acting on the box

Explain your reasoning
Explanation:
After a week the plant will have grown out and toward the window. the plant will not be standing straight up, so it will be laying down toward the window. Because the plant is leaning toward the window, where the sun shines in, it proves that plants grow toward sunlight.
