A) hydrophobic interactions
B) nonpolar covalent bonds
C) ionic bonds
D) hydrogen bonds
E) both A and C
Answer:
2. C
3. D
Explanation:
2. Ionic bonds are chemical bonds that forms between the ions of molecules or compounds. The two molecules are joined together by an electrostatic force. This is the case of the bond that forms between the slight negative charge (anion) at one end of a water molecule and the slight positive charge (cation) of a second water molecule.
3. Cohesion refers to the attraction of a molecule to a like molecule. The cohesiveness of water molecule to another water molecule is great due to the HYDROGEN BONDS that forms between them.

cell. Some tumor cells are benign, while others are malignant. How does the presence of an
oncogene lead to the formation of a tumor? option choices
F ATP production is inhibited.
G Somatic cell growth is inhibited.
H Cell division is unregulated.
J Antibody activity is unregulated
Answer:
H Cell division is unregulated.
Explanation:
Oncogenes are genes that, when mutated or somehow rendered overactive, cause cells to proliferate uncontrollably. This is a hallmark of cancer.
These genes make proteins with a range of functions, for example, signalling proteins, enzymes, transcription factors. What they have in common is that they promote cell growth and division.

Answer:
What are the symptoms of Hypohidrotic ectodermal dysplasia?
Hypohidrotic ectodermal dysplasia (HED) is a genetic skin disease. Common symptoms include sparse scalp and body hair, reduced ability to sweat, and missing teeth. HED is caused by mutations in the EDA, EDAR, or EDARADD genes .
No, all the individuals who have the spongy tiny pore allele do not show it in their physical appearance.
Only those individuals in which this spongy tiny allele is dominant over other alleles will be appeared in their physical appearance whereas those individuals in which this allele is present as a recessive allele then it will not appear in their physical appearances so we can conclude that only dominant allele will appear in the physical appearance of an individual.

Explanation:
Since the student is studying the earth, the core area is made up of a solid metal ball in the middle of a pool of a liquid.
The core is the inner most part of the earth. It exists in the middle of the earth. The core is divide into two layers; inner core and outer core. The inner core is a solid ball of metal. The outer core is a liquid metal under high temperature and pressure.The ultimate goal of sustainable development is to limit the future use of resources b. meet current and future resource needs C. increase the current use of resources d. reduce resource use but increase supplies
The correct answer is B. Meet current and future resource needs.
Explanation:
Sustainability implies an equilibrium between the natural resources available and the resources humanity requires. This equilibrium is reached when the natural resources extracted from nature are enough to satisfy human needs without depleting the resources or causing these are not available in the future. In this context, the goal of sustainable development is to make sure now and in the future resource needs are meet (option B). Moreover, this is possible through actions such as recycling, reducing deforestation, creating environment-friendly technologies, among others that reduce the depletion of resources or preserve the environment.

Today, we push economies to grow whether or not they make us thrive. Especially in the richest countries, we should strive for economies that make us
thrive whether or not they grow." What type of economic model does this statement represent?
A. Classical economics
B. Threshold economics
C. Supply-side economics
D. Doughnut Economic Model
Answer:
D. Doughnut Economic Model
Explanation:
The "Doughnut Economic Model" is focused on the benefits that people can get in its economy rather than its growth. This situation is also known as the "circular economy," which deems thriving as more important than growing. The doughnut is represented by different things. The middle hole refers to the poor people in the society. The inner ring refers to the things we need in order to thrive in life while the dough refers the the area where people meet their needs. All of these interact within a circle, thus the term circular economy.
When you perform a three-point test cross to determine the linkage between three genes, you found that distance between the three genes were 16 and 8 map units. Of 1000 progeny produced in the test cross, you observe 7 double recombinants. What is the interference?
a. 0.547
b. 0.453
c. 0.16
d. 0.08
e. 0.0128
Answer:
The correct option is b. 0.453
Explanation:
To calculate the coefficient of coincidence, CC, we must use the next formula:
CC= observed double recombinant frequency/expected double recombinant frequency
Note:
• Observed double recombinant frequency=total number of observed double recombinant individuals/total number of individuals
• Expected double recombinant frequency: recombination frequency in region I x recombination frequency in region II.
CC= (7/1000)/0.16x0.08
CC= 0.007/0.0128
CC=0.5468
The coefficient of interference, I, is complementary with CC.
I = 1 - CC
I = 1 - 0.5468
I = 0.4531

What ensures that blood levels of a specific releasing hormone are locally high in order to stimulate the pituitary?
Answer:
The correct answer is: hypothalamic-pituitary portal system.
Explanation:
The hypothalamic-pituitary portal system, also called the hypophyseal portal system, is a system of blood vessels that connect the hypothalamus with the anterior pituitary to transport hormones between these two glands.
The hypothalamus and the anterior pituitary are a hugely important part of the endocrine system, since many hormones are secreted by these glands. Not only that but the hormones released by the hypothalamus have a direct effect on the hormones released by the anterior pituitary gland, which affects different peripheric glands as well. For example, the hypothalamus releases the thyrotropin-releasing hormone, which stimulates the anterior pituitary to release the thyroid-stimulating hormone, which stimulates the thyroid to secrete thyroid hormone. This sort of information between the hypothalamus and the anterior pituitary is transmitted thanks to the hypothalamic-pituitary portal system, which has fenestrated capillaries that allow an even faster exchange between the glands. If the blood in this portal system has high levels of, for example, the thyrotropin-releasing hormone, the anterior pituitary will soon start releasing the thyroid-stimulating hormone.
if you wanted to test red blood cells for their ability to complete glycolysis, what compound would you try to detect
Answer:
Pyruvate
Explanation:
Glycolysis refers to the pathway through glucose is oxidized to pyruvate.
In glycolysis, a molecule of glucose passes through ten enzyme catalyzed steps to yield two molecules of pyruvate.
Step 1: Glucose is phosphorylated to form glucose-6-phosphate
Step 2: Glucose-6-phosphate is converted to fructose-6-phosphate
Step 3: Fructose-6-phosphate is further phosphorylated to form fructose-1,6-bisphosphate
Step 4: Fructose-1,6-bisphosphate is cleaved into glyceraldehyde-3-phosphate and dihydroxyacetone phosphate
Step 5: Dihydroxyacetone phosphate is converted to another molecule of glyceraldehyde-3-phosphate.
Step 6: Two molecules of Glyceraldehyde-3-phosphate are converted to two molecules of 1,3-bisphosphoglycerate
Step 7: Two molecules of 1,3-bisphosphoglycerate are converted to 3-phosphoglycerate
Step 8: Two molecules of 3-phosphoglycerate are converted to two molecules of 2-phosphoglycerate
Step 9: Two molecules of 2-phosphoglycerate are converted to two molecules of phosphoenolpyruvate
Step 10: Two molecules of phosphoenolpyruvate are converted to two molecules of pyruvate, the end-product of glycolysis.
Therefore, the presence of pyruvate molecules in red blood cells can be used to test for their ability to complete glycolysis
