a. Sabita is blind from a diet devoid of fortified milk, animal products, or dark yellow and orange fruits and vegetables.
b. Sabita has an enlarged thyroid gland due to a dependence on unfortified salt.
Nutrient:
1. Iron
2. Vitamin A
3. Vitamin D
4. Iodine
Answer:
a. Sabita is blind from a diet devoid of fortified milk, animal products, or dark yellow and orange fruits and vegetables. - Vitamin A
Sabita is suffering from Vitamin A deficiency. A lack of Vitamin A usually shows itself with night blindness but can cause complete blindness if not acted upon quickly.
Vitamin A deficiency is quite common in developing or poorer nations such as the area Sabita is located and usually attacks children of women in their reproductive stage. Sources of vitamin A include; fortified milk, animal products and fruits and vegetables.
b. Sabita has an enlarged thyroid gland due to a dependence on unfortified salt. - Iodine
Iodine deficiency leads to an abnormal enlargement of the thyroid gland leading to a condition known as Goiter which presents itself as a big bulge in a person's neck. Iodine is usually placed in fortified salt along with iron to reduce iodine deficiency so Sabita's dependence on unfortified salt is robbing her of a great source of Iodine.
The condition in which the body is deprived of minerals, vitamins and other macro and micronutrients are called malnutrition.
The correct matches and their explanation are as follows:
a. The correct answer is:
Option 2. Vitamin A
Sabita is blind from meals deficient in fortified milk, animal products, fruits and vegetables due to Vitamin A deficiency.Night blindness is a common symptom of a Vitamin A deficiency.It is most common in developing regions due to the lack of proper meals. The best source of vitamin A is milk, fruits and animal products like eggs.b. The correct answer is:

Knowledge of the driver mutations underlying cancer has led to targeted therapeutics, such as the protein kinase inhibitor imatinib (trade name Gleevec) in cases of chronic myeloid leukemia. Cancer cells often become resistant to a given drug, so researchers continue searching for new drugs that target proteins that contribute to the cancerous phenotype. One recent promising approach uses drugs that lead to ubiquitination and proteasomal degradation of the target protein. Which of the following mutated proteins are good candidates for this approach?
A) oncogenes
B) proteins with loss-of-function mutations
C) proteins with gain-of-function mutations
D) tumor suppressor genes
Answer:
C) proteins with gain-of-function mutations
Explanation:
Gain-of-function mutations: In biology, the term "gain-of-function mutation" is described as one of the different types of mutation in which the altered or changed "gene product" consists of an entirely new pattern or molecular function associated with gene expression. However, the "gene-of-function mutations" are being always considered as "Semidominant or Dominant".
In the question above, the correct answer is option C.

41 Explain why you needed to use a water plant for this experiment
I suspect you are referring to a specific experiment, which measures the rate of photosynthesis at differing intensities of light. This experiment could certainly be done with land plants, but using a water plant makes it easier to have a simple way to measure the rate of photosynthesis--the counting of bubbles which come off a specific area of the plant. A water plant such as elodea (the type you commonly see in aquariums) does the process of photosynthesis just as plants that grow in the air do, but you can actually see the bubbles that indicate photosynthesis is occurring--they form on the leaves before they float to the surface, enabling an easy measurement of bubbles per minute.
Plants have chloroplasts, which in addition to giving plants their green color, perform photosynthesis, the process on which life on earth is dependent. They use the energy of the sun to use carbon dioxide and water to produce sugars and oxygen. When you are counting the bubbles on the underwater leaf, you are counting bubbles of oxygen formed during photosynthesis.

Explanation:
In a scientific research, the "Analysis" section is where the specific research data and the interactions and information that can be extracted from them are analyzed, in a succinct and explanatory way. This section is very important to present how these data were acquired and how they work within the theme developed in the research.
The section called "conclusion", in turn, presents the section where the research will conclude the established theme, showing an affirmation discovered through the research or suggesting additional research that will help to establish an efficient conclusion.
Alex, his mother, his father, and his older sister have blood type B. His younger sister and his brothers have type O. Anna, her mother, her father, and her younger brother have type A. Her sister and her older brother have type O. If Alex and Anna have three children, what is the probability at least two of them will have type O
Answer:
25%
Explanation:
the probability at least two of them will have type O can be solved as follows
Let the chances be
(Chance of Alex is I^B I ) x (1-none have type O) X (Chance of Anna is I^A i)
=>>(2/3) x (1-.75 3 ) x (2/3)= 0.25
So 0.25x 100 = 25%
The blood type of the offspring is dependent on the probable blood type
their parents.
The probability that at least 2 of them will have type O is [tex]\underline{\frac{5}{144}}[/tex]
Reasons:
Alex; Both parents are [tex]I^Bi[/tex]

Probability that [tex]I^Bi[/tex] from Alex = [tex]\frac{2}{3}[/tex]
Probability that [tex]I^Ai[/tex] from Anna = [tex]\frac{2}{3}[/tex]
Probability that two have type O = [tex]\frac{2}{3}[/tex] × [tex]\frac{2}{3}[/tex] × [tex]\left(\frac{1}{4}\right)^2[/tex] = [tex]\frac{1}{36}[/tex]
Probability that three have type O = [tex]\frac{2}{3}[/tex] × [tex]\frac{2}{3}[/tex] × [tex]\left(\frac{1}{4}\right)^3[/tex] = [tex]\frac{1}{144}[/tex]
Probability that at least two have type O is

essential to survival."
A. False, it should read, "Instinctive behavior is present from birth, is developed through observation and experience, and allows animals to adapt to
changes in the environment."
False, it should read, "Instinctive behavior is not inherited, requires no thought, and is developed through experience and observation."
C. True
False, it should read, "Learned behavior is not inherited. It is developed through observation and experience and allows animals to adapt to
changes in the environment."
Answer: It is, (False, it should read, “Learned behavior is not inherited. It is developed through observation and experience and allows animals to adapt to changes in the environment.”)
Explanation:
The statement is false, it should read, "Learned behavior is not inherited. It is developed through observation and experience and allows animals to adapt to changes in the environment."
What is learned behavior?Learned behaviors are those behaviors or characteristics that we learn from observing other people, learning and reading, and our experiences. It is the best type of characteristic of humans because learning just by observation is very efficient.
This behavior can not be inherited by another person because it is not in our genes. The behavior can be acquired by nature and the learning ability of a human, not inheritance. The genetic qualities are only inherited.

The CT reveals several issues with the cranial structure, one of which might be in the cribriform plate but the image isn't well defined. What non-invasive test can you do to test if the cribriform plate is severely damaged? Why?
The non-invasive test that can be used to test if the cribriform plate is severely damaged is called the pledget study.
CRIBRIFORM PLATE is the part of the ethmoid bone that forms the nasal cavity.
The olfactory nerve which is part of the cranial nerves passes through the small opening found in the cribriform plate.
A damage to the cribriform plate leads to cerebrospinal fluid (CSF) leak which usually comes out from the nose and ears.
Therefore to test if the cribriform plate is severely damaged, the pledget study is performed.
Pledget study is a non-invasive method of diagnosing a CSF leak.
To perform this test,
Cotton pads called Pledgets are placed in the nostrils.If the leaking fluid contains CSF it will be detected.The presence of CSF shows that there is damage to the cribriform plate.
This method is non invasive because it doesn't require the breaking or opening of any part of the body.

Explanation:
Describe at least 2 benefits and 2 drawbacks there might be for animal cells (including humans) to make their own food through photosynthesis.
Answer:
here.
Explanation:
Benefits would be that we'd be autotrophs, meaning that we'd be independent of an external source of organic compounds for energy. All we'd need is the sun and carbon dioxide. It's a simpler and less energy-consuming process than having to undergo digestion, absorption and then assimilation.
Cons would include the fact that it provides a very limited amount of energy only for the day. Which means humans will be inactive at the night time because the energy won't be able to support our activities. Since we don't have a surface area as big as leaves, our deep cells (like those of our organs and bones) will suffer most from the lack of energy since sunlight cannot penetrate our fat, muscles and bones. This can cause organ failure if our cells solely depended on diffusion.
Our high metabolic rate and our need for energy makes photosynthesis very very ineffective.
The precursor of EGP is translated from a transcript that has had one non templated nucleotide added to the open reading frame. This change does not create or eliminate a stop codon. Compared with the protein sGP, which is produced from the unedited transcript, EGP most likely has the same primary:
Answer:
Explanation:
It was added somewhere in the middle. Since this is a frameshift, everything downwind of the addition will most likely be different.
The question is basically asking, if you change everything from the middle to the end of an amino acid sequence, which end changes and which end would remain the same?
It basically asks, when amino acids are assembled into proteins, are they built from the amino to the acid direction, or the acid to the amino direction?
The answer is that amino acid sequences are always assembled N to C, much like nucleotide sequences are built 5 to 3.
