How many chromosomes does this cell have?
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.

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).

How do most primary producers make their own food? *
Explanation:
most primary producers are plants and they produce food by photosynthesis. In photosynthesis they use carbon dioxide, water and light (most times sunlight) to make glucose and oxygen. the glucose is their food and oxygen is the waste product and is given out.
Most primary producers make their own food through the process of photosynthesis.
What is photosynthesis?Photosynthesis is a biochemical process that occurs in the chloroplasts of plant cells (as well as in certain algae and some bacteria) and uses energy from sunlight to convert carbon dioxide and water into glucose (a simple sugar) and oxygen.
The chlorophyll pigment in chloroplasts captures light energy, which is then used to drive the synthesis of glucose through a series of chemical reactions.
This process allows primary producers to produce organic compounds and serve as the foundation of the food chain by converting sunlight energy into chemical energy that other organisms can consume.

Please answer quickly!! Timed test! Which term is correctly paired with its role in the body? 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.

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.

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.
