A man has Huntington's disease (a dominant trait) and a heterozygous genotype. He has four children with a woman who does not have Huntington's disease. What are the odds their children will inherit Huntington's disease?

Answer: Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. The following description of this three-stage process applies generally to all cells, but specific variations within the process may occur depending on organism and cell type.

QUESTION:

ANSWER:

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, like the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication.

The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands. As the helicase moves along the DNA molecule, it continues breaking these hydrogen bonds and separating the two polynucleotide chains

Meanwhile, as the helicase separates the strands, another enzyme called primase briefly attaches to each strand and assembles a foundation at which replication can begin. This foundation is a short stretch of nucleotides called a primer

After the primer is in place on a single, unwound polynucleotide strand, DNA polymerase wraps itself around that strand, and it attaches new nucleotides to the exposed nitrogenous bases. In this way, the polymerase assembles a new DNA strand on top of the existing one

Answer:

To find out the impact of environment on the physical structure of lizard and natural selection.

Explanation:

Ecologists conduct an investigation on the survival of a species of lizards in order to study the impact of environment on the physical body of lizard and natural selection. The ecologists find out that environment has direct impact on the body structure of lizard. Those lizards that spend more time on the ground, have longer legs in order to run fast, while on the other hand, species that lives in the trees usually have shorter legs in order to easily climb on the trees so these body structure helps them in survival and movement.

EDGE 2022

Answer:

A. Fish need light to see their food

Explanation:

B is incorrect because fish take in oxygen constantly to respirate. If they only took in oxygen when it was dark they would die.

C is incorrect because expelling CO2 is also a constant process as a part of the reactions that take part inside living organisms, so it happens constantly (a bit like B)

D is incorrect because plants need light for food (photosynthesis) and would most likely die or have stunted growth if left in the dark.

A is correct because when it is dark, fish rely on other senses to find food as most fish cannot see as well in the dark, therefore when they have light they can see their food more easily.

compound

Explanation:

as cited from coolgalapagos.com, "Molecules made of more than one kind of element are called compounds. A compound is formed when one kind of atom (an element) joins to at least one other kind of atom of a different element."

Explanation:

Answer:

Uranium 238

Potassium 40

Rubidium 87

Explanation:

Answer:

The correct answer is -

1 - The stimulus is received by sensory receptors.

2 -  Sensory neurons carry stimulus information to the brain or spinal cord.

3 -  The brain processes the information through interneurons.

4 -  Interneurons transfer response information to motor neurons.

5 - Motor neurons cause muscles to contract so the body can react to the stimulus.

Explanation:

In most of the organism including humans body response according to the stimulus it receives. The stimulus is received by the sensory receptors to the sensory neurons or afferent neurons that are present on the skin, nose tongue ears, or eyes. Many other receptors and pain receptors present on various internal organs as well.

These sensory neurons carry the stimulus to the spinal cord or brain where this information received by the stimulus process through interneurons and transfer the response of the particular stimulus to the motor neurons. These motor neurons result in muscles contracts so the body can react.

Answer: Organisms evolve over time due to changes in heritable physical characteristics.

Explanation:

There are a few things to look for when distinguishing between a nonscientific theory and a valid scientific theory. One thing to consider is if there are any published literature, experimental studies, and data available to support the theory. Most scientific theories have data and information tied to them. Another factor to examine is who has developed the theory. A scientific theory will always be supported by evidence with large quantities of data and testing. An example of a scientific theory is the theory of evolution, which observes changes in heritable physical traits over time in an organism. A hypothesis might be that all organisms evolve at the same rate.

Organisms evolve over time due to changes in heritable physical characteristics is an example of a scientific theory known as evolution. Thus, option C is correct.

Evolution is the scientific theory that explains that "a change in the characteristics of biological populations over next generations.

According to scientists RNA is the first existing molecule on earth that replicate by itself and the process of evolution lead to advanced forms of life.

These characteristics are easily trasfered from one generation to other generation.

Therefore, Organisms evolve over time due to changes in heritable physical characteristics is an example of a scientific theory known as evolution. Thus, option C is correct.

Answer:

D

Explanation:

A It allows the lodgepole pine tree to make more seeds in cones that are hard to open. IS WRONG B) It creates more wildfires for the lodgepole pine tree to reproduce. IS WRONG C) It makes the seeds travel and grow in areas where there are no wildfires. DEFINITLY NOT so that leaves it with D  It helps the lodgepole pine tree to protect the seeds and to reproduce.
