b) Explain why a leaf cannot be tested for starch by adding iodine solution directly.
Answer:
Due to presence of waxy layer.
Explanation:
A leaf cannot be tested for starch by adding iodine solution directly because waxy cuticle covering the leaves that prevents the penetration of iodine in the leave cells. First, the waxy layer should be removed by boiling the leaves that causes disruption in the cell membranes that make easier for the iodine to penetrate in the leave cells so that's why iodine can not be tested for starch directly.

Read the paragraph from the section "Types Of
Isolation."There are biological properties of organisms
that prevent breeding across different species. They are
known as reproductive isolating mechanisms (RIMs). A
mechanism is a process or method. Which option is the
BEST definition of "properties" as it is used in the
paragraph above?
The correct answer is B. Traits or features that take effect.
Explanation
Property is a word to designate any quality that identifies identifying something or someone, distinguishing it from its peers. It can refer to different issues such as its characteristics, capabilities, possibilities, physical appearance, among others. According to the text, "There are biological properties of organisms that prevent breeding across different species". So the answer is B. Traits or features that take effect.

Answer:
- The building blocks of DNA molecules are amino acids. False
- DNA molecules contain a 5-carbon sugar called deoxyribose. True
- The nitrogen bases found in DNA molecules include adenine, cytosine, guanine, and thymine. True
Explanation:
The building blocks of the deoxyribonucleic acid (DNA) are nucleotides, while amino acids are the building blocks of proteins. Each nucleotide consists of one of four possible nitrogenous bases: two purines (i.e., adenine and guanine) and two pyrimidines (i.e., cytosine and thymine). In DNA, each nucleotide consists of one of these four nitrogenous bases, a five-carbon sugar molecule (called deoxyribose), and a phosphate group. The DNA molecule has a double-helix structure, where nitrogenous bases are inside the double helix while sugars and phosphates are outside. In DNA, cytosine always pairs with guanine and thymine always pairs with adenine.

If a DNA strand contains 12% thymine, it also contains ____
a. 12% A, 38% G, 38% C
b. 12% A, 12% G, 38% C
c. 12% A, 12% G, 12% C
d. 38% A, 12% G, 38% C
Answer:
If G = 14, then C = 14 and G + C is 28. Thus A + T. The percent of adenine in a double-stranded DNA is 38. Therefore G + C = 100 - 76 = 24, and C = 24/2 = 12 percent.

Newton's 2nd Law is F= ma. Write a problem that gives the mass and the acceleration of an object and asks us to find the force.
Answer:
An object having a mass of 20kg is pushed by John and it then accelerates down the inclined plane at a rate of 0.5m/s². Find the force applied on the object.
Explanation:
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
For example, an object having a mass of 20kg is pushed by John and it then accelerates down the inclined plane at a rate of 0.5m/s². Find the force applied on the object.
Given the following data;
Mass = 20kg
Acceleration = 0.5m/s²
To find the force;
Force = mass * acceleration
Substituting into the equation, we have;
Force = 20 * 0.5
Force = 10 Newton.

A 30-year-old male demonstrated a subtle onset of the following symptoms: dull facial expression; droopy eyelids; puffiness of the face and periorbital swelling; sparse, dry hair; dry, scaly skin; evidence of intellectual impairment; lethargy; a change of personality; bradycardia (60 b/min) low range of normal; a blood pressure of 90/70 low BP; anemia low iron – cant transport O through body very well(hematocrit 27); enlarged heart (upon radiological exam); constipation, and hypothermia. Plasma concentrations of total and free T4 and T3 follow:
Radioimmunoassay (RIA) of peripheral blood indicated elevated TSH levels. A TSH stimulation test did not increase the output of thyroid hormones from the thyroid gland.
a. What endocrine organ is involved here?
b. Is this a primary or secondary disorder? Why? (Is a TSH or TRH determination necessary for your diagnosis?)
c. Describe the feedback loop involved, indicating if there is an increased or decreased TSH level.
d. List several defects that could cause these symptoms.
e. Would you expect to find a palpable goiter? Explain your answer.
f. Describe a suitable treatment for this individual.
Answer:
1. Thyroid gland is the endocrine gland that is involved here.
2. TSH stimulation test did not show an increase in the output of thyroid hormones secreted from thyroid glands which makes it a primary disorder. The determination of TSH or TRH gives an idea about hypothyroidism if it is due to feedback inhibition of the pituitary or absence of TSH hormone from the pituitary, however, Circulating levels of TRH not necessary.
3. The feedback loop involves the following:
TRH hormone secreted from the hypothalamus triggers the anterior pituitary to secret TSH that in turn triggers the relapsing of the T3 and T4 levels by the thyroid glands. If there is a low level of T3 and T4 hormones then negative feedback takes place and increases the TSH output.
4. symptoms:
Not able to uptake the iodide into the cells of the thyroid gland
Defects in the conversion of iodide to iodine
tyrosine molecule iodization
secretion of the hormones from the Tg molecules
Less TSH receptors on the gland.
5. The chronic TSH stimulation due to negative feedback may cause hypertrophy of the gland, results in goiter formation.
6. synthetic hormone therapy is known as Synthroid such asT4 (L-thyroxine).

Proteins are a type of biomolecule with a wide variety of functions. Which statement is correct about the digestive system and proteins?
Question 1 options:
Enzymes in your saliva start breaking down the carbohydrates in food
Ready to use energy is released as the protein is broken down
The large intestine absorbs proteins for use in cells.
The liver manufactures bile salts that help break down fats in proteins
Answer:
Enzymes in your saliva start breaking down the carbohydrates in food
Explanation:
It makes sense, your digestive system consists of your mouth, esophagus, stomach, pancreas, liver, gallbladder, small intestine, large intestine, and anus. As soon as you put food in your mouth you break down your food. Also I took the test, hope you make an good grade!!!
The statement 'enzymes in your saliva start breaking down the carbohydrates in food' is correct about the digestive system and proteins.
The digestive system is an organ system where organs work together to digest foods.Enzymes are specific proteins that carry out specific chemical reactions.Digestive enzymes such as amylase are secreted by the salivary glands in order to help with the digestion of foods.
In conclusion, the statement 'enzymes in your saliva start breaking down the carbohydrates in food' is correct about the digestive system and proteins.
