2. Tim and Stephanie are devastated when the
recessive disease. Tim is shocked because
would have gotten it from him. Is Tim ce
genotypes must be in order for neither of them have the disease but have a son who does
Answer:
Explanation:
Tim and Stephanie are devastated when they find out their newborn son has hemophilia- sex-linked recessive disease. Tim is shocked because he doesn’t have hemophilia, and figured if his son has it he would have gotten it from him. Is Tim correct in his thinking? Explain. Also explain what their genotypes must be in order for neither parents to have the disease but their son does. Create a Punnett square, and indicate the mother's and father's genotype.
First of all, the thinking of Tim is wrong. Hemophilia is X-linked and a male (XY) child always inherits his X chromosome from his mother. Hence, the newborn son of Tim must have inherited the allele for the disease from Stephanie.
Now, neither Tim nor Stephanie showed any symptom of hemophilia. It could only mean that Tim is totally free of the hemophilic allele while Stephanie is a carrier for it. Because a man has just one X chromosome, he can either be totally free of the abnormality or affected by it, no in-between. A woman has two X chromosomes, hence, she can be totally free, a carrier, or affected for the disease. Assuming the allele for hemophilia to be h, Tim's genotype would, therefore, be [tex]X^HY[/tex] while that of his wife would be [tex]X^HX^h[/tex] .
The Punnet's square analysis of the cross between Tim and Stephanie is indicated in the attached image.

Answer: This is because sharks are pregnant for 6 months to 2 years. Which decreases shark population due to slow birth rates. This also effects female sharks health die to the stress of carrying many sharks for up to 2 years. Most sharks die before or after giving birth. Overfishing for sharks is rapidly decreasing the shark population due to slow breeding but many fisherman. Less females and males are able to mate and sharks are pregnant for so long that the female has a high percentage of getting caught. In the long run more and more sharks are being killed each year which decreases sharks population for obvious and non obvious reasons.

Corals grow in dense groups on the floor of the ocean. Which type of distribution pattern does this represent, and what is the advantage of this distriubtion?
Answer:
Clumped distribution
Explanation:
Clumped distribution is a type of distribution in which organisms are clustered in groups. This is the most common form of distribution. Clumped distribution occurs in environment that are patchy (the patches are the part suitable for the organism to live in).
Clumped distribution is good because organisms have better protection from predators providing defense, and there is more access to food resources.
Since the Corals grow in groups on the ocean floor, hence it is a form of Clumped dispersions.
One farmer plans to grow soybean. Soybeans grow best in medium loam soil. Which of these is the most likely soil sample that the farmer would select to grow soybeans? Question 16 options: sample containing 40 percent sand, 15 percent clay, and 45 percent silt sample containing 25 percent sand, 15 percent clay, and 60 percent silt sample containing 55 percent sand, 30 percent clay, and 15 percent silt sample containing 30 percent sand, 35 percent clay, and 35 percent silt
Answer:
The correct answer is - sample containing 30 percent sand, 35 percent clay, and 35 percent silt.
Explanation:
The loam soil is a type of soil that is made from an equal amount of all three components are; sand, silt, and clay. Loam can be distinct as medium loam with little variation of the percentage of the components.
This type of soil is very useful for creating soil for gardens or farm soils as it provided a nice hold on the moisture and also provide enough air to the roots due to drain well property.
Among all the options last option has almost the same amount of the components of the soil, sand - 30 %, silt - 35 %, and clay - 35%
Answer:The correct answer is - sample containing 30 percent sand, 35 percent clay, and 35 percent silt.

4. Which phrase best describes cancer?
a. absence of cyclins
b. multiple gene mutations
c. uncontrolled cell growth
d. presence of genetic defects
Answer:
B: Multiple gene mutations
Explanation:
Mutations can be very small changes, affecting only a few nucleotides or they can be very large, leading to major changes in the structure of chromosomes. Both small and large mutations can affect the behavior of cells. Combinations of mutations in important genes can lead to the development of cancer.
Uncontrolled cell growth phrase best describes the Cancer. So, the correct option is (C).
What is Cancer?
Cancer is a disease which caused when the cells divide uncontrollably and it is spread into surrounding tissues. Cells which are divided uncontrollably they are abnormal in nature and also spread to different parts of the body. These cells may form in the lumps of tissues known as Tumors. They are of two types - Cancerous and Non-Cancerous (benign).
Cancerous tumors spread to the nearby tissues or invade into it. It can travel to different places in the body to form new tumor which is called metastasis. Cancerous tumors are also called malignant tumors. Mots of the cancers occur from the solid tumor but in case of blood cancer, it is not.
It is mainly caused by the alteration of DNA. Genetic changes that cause cancer can occur because
Some errors which occur when the cells divide. Damage to DNA which caused by harmful substances in the environment, such as the chemicals in tobacco, smoke, etc.It can be inherited from the parents.Thus, uncontrolled cell growth phrase best describes the Cancer. So, the correct option is (C).

What are the building blocks of proteins? If all proteins are made of the same
building blocks, how can there be so many different types of proteins with different
functions?
Answer:
The basic building blocks of proteins are called amino acids. In proteins, amino acids are arranged into a linear molecule called a polypeptide chain. Some proteins only consist of a single polypeptide chain while more complex proteins are made out of multiple polypeptide chains bonded together.
Explanation:Proteins are formed out of long linear molecules of amino acids called polypeptide chains. The identity and function of a protein are determined by its sequence of amino acids and the 3-D structure of its polypeptide chains. Amino acids are stored in DNA in the form of sequences of nucleotide bases.

Answer:
Not all DNA that was found at the scene has to be related to the scene.
Explanation:
Just because DNA was found at the scene, that doesn't mean that the person there is actually guilty. For example, in a case where person B is guilty, a strand of hair from Person A could be carried over to another scene on Persons B's clothing.
Answer:
Because DNA is more reliable than other forensics, scientists have shrugged off suggestions that it could fall victim to the vagaries of bias. But Dror noted that much DNA analysis involves interpretation. With interpretation comes subjectivity, and with subjectivity can come error. Only one-tenth of 1 percent of human DNA differs from one individual to the next and, although estimates vary, studies suggest that forensic DNA analysis is roughly 95 percent accurate.

An earthquake occurred three hundred miles off the shoreline, and massive flooding occurred on land as a result.
Which best describes what occurred?
- Continental shifting resulted in a tsunami.
- Continental shifting resulted in a volcano erupting.
- Tidal activity in the subduction zone caused a tsunami.
- Tidal activity in the subduction zone caused a volcano to erupt.
Answer:
An earthquake occurred three hundred miles off the shoreline, and massive flooding occurred on land as a result. Which best describes what occurred? Continental shifting resulted in a tsunami.
Explanation:
The best thing that describes the scenario that occurred is tidal activity in the subduction zone caused a tsunami. The correct option is C.
What is tsunami?The violent breaking of rock during an earthquake releases energy that travels through the earth in the form of resonance known as seismic waves.
These seismic waves radiate from the hypocenter in all directions, becoming weaker as they travel further away from the hypocenter.
Tsunamis are a series of large waves with extremely long wavelengths and periods that are usually caused by a violent, impulsive undersea disturbance or activity near the coast or in the ocean.
When a large earthquake ruptures, the faulting can cause vertical slip large enough to disturb the overlying ocean, causing a tsunami to travel in all directions.
Thus, the correct option is C.

A) Insulin – a sugar that regulates blood glycogen levels B) ADP – a molecule that releases energy when it forms ATP C) Glycogen – a hormone found in blood that regulates blood glucose levels D) Glucose – a sugar found in blood that can be broken down to produce ATP
Answer:
The correct answer is - D) Glucose – a sugar found in blood that can be broken down to produce ATP
Explanation:
Insulin is a hormone produced by the beta cells of pancrease that takes up the glucose from the bloodstram and make gucose available to the cells of the body to produce energy by the process of cellular respiartion. Glucose is breaken down to its smaller units and produced high amount of energy in the form of ATP. Glycogen is form of sugar that is stores in the muscle and othe cell for the energy in abscence or low glucose level in blood stream. ADP is a molecule know as adesnosine pyrophosphate or diphosphate which is play role in flow of energy. ADP molecules requires energy to form ATP molecule and when ATP splits into ADP and Pi releases high amount of energy.

i would really like help pls
Answer:
1. B
2. C
3. A
Explanation:
1. Most of the carbohydrates in the foods you eat are digested and broken down into glucose before entering the bloodstream. Glucose in the blood is taken up into your body's cells and used to produce a fuel molecule called adenosine triphosphate (ATP) through a series of complex processes known as cellular respiration.
2. Fats are known as being a long term energy source, and the fat on your body is used a "cushioning" for your bones.
3. To break a protein down into its amino acids you will need enzymes. Enzymes are biological molecules (proteins) that act as catalysts and help complex reactions occur everywhere in life.
