why do sun spots appear darker than their surroundings
Answer:
they are comer than their surroundings.
Sunspots are cooler because their magnetic fields inhibit the replenishing of heat from convective flows (due to the interaction between plasma and magnetic fields). This allows them to cool radiatively. The rest of the solar surface is constantly being replenished by convective cells that reheat it.
Answer:
because they are significantly cooler than the rest of the Sun's surface Despite their gloomy appearance, they are nonetheless extremely hot. A sunspot would shine brightly if it were alone in space.

To gather information about the outbreak, 410 persons related through a densely connected set of social or sexual associations were interviewed. What can public health workers tell individuals in this network to stop the spread of Gonorrhea in this population?
a) Preventive treatment with penicillin will prevent Gonorrhea infection in individuals not already infected.
b) Only individuals with symptoms should seek medical screening since all cases of Gonorrhea are associated with symptoms.
c) Condoms will not prevent the spread of Gonorrhea. Gonorrhea can spread from an infected mother to a fetus.
d) Gonorrhea is more prevalent in individuals 24 years and older.
Answer:
c) Condoms will not prevent the spread of Gonorrhea. Gonorrhea can spread from an infected mother to a fetus.
Explanation:
To prevent the spread of infection, it is important that healthcare professionals inform people about ways to protect themselves against infection. In addition, it is important that health professionals inform the dangers that this infection can cause, such as symptoms and rapid transmission, which can even happen from mother to fetus. On how to protect themselves, health professionals can say that the use of condoms is the most efficient form of protection.

At this point, the writer is considering adding the following sentence. Successful nerve impulse transmission depends not only on myelin sheaths, but also on the presence of ion pumps embedded in the cell membrane. Should the writer make this addition here?
A) Yes, because it describes how the presence of ion pumps is related to the functions of cholesterol.
B) Yes, because it supports the passage’s main argument with a second example of cholesterol’s potential adverse health effects.
C) No, because it identifies a relationship between the nervous system and ion pumps that has already been discussed.
D) No, because it interrupts the paragraph’s discussion of cholesterol’s functions with loosely related information.
Answer:
D) No, because it interrupts the paragraph’s discussion of cholesterol’s functions with loosely related information.
Explanation:
The passage was discussing the importance of cholesterol in nerve impulse transmission. Its presence in the myelin sheaths of nerve cells speeds up nerve impulse transmission. It will not be wise for the author to now bring in the relationship between nerve impulse transmission and ion pumps. This is because the main topic under discussion is cholesterol and its importance. The sentence should be continued with other importance of cholesterol and not ion pumps.

Muscle weakness is associated with Vit A/ Vit E/ Vit K/ Protein deficiency
Answer:
Low vitamin E levels may result in Muscle weakness: for the central nervous system, vitamin E is vital. It is one of the major antioxidants in the body and a shortage causes oxidative stress that can lead to weakening in muscles.
Explanation:
The body needs to work with vitamin E and become a necessary vitamin. It is fat-soluble, thus it has to be effectively absorbed in fat from the food. Before being released to the bloodstream for usage, vitamin E is mostly kept in the liver.
The deficiency is unusual and usually caused by an understatement. There are also modest levels of preterm newborns.
Eight kinds of vitamins exist. A blood test allows a physician to know how much a person has of an alpha-tocopherol form. Use this information to establish if the total vitamin E level of a person is present.
A standard level is typically between 5.5 and 17 milligrams (mg/L) per litre. For premature infants and youngsters under 17 years, the typical range may be different. The Normal scope may also be somewhat different amongst laboratories.
If an adult has less than 4 mg/L of vitamin E in his or her blood, supplementation is usually necessary.
Under normal conditions the sympathetic division is usually active in the body resting heart rates are influenced by nor epinephrine the parasympathetic system keeps heart rate lower than the heart would beat on its own. all of the above are true
Answer:
the parasympathetic system keeps heart rate lower than the heart would beat on its own.
Explanation:
The parasympathetic nervous system (PNS) is one division of the autonomic nervous system. The vagus (parasympathetic) nerves that innervate the heart release acetylcholine in order to slow the heart rate by decreasing the slope of the pacemaker potential. Acetylcholine activates a type of G-coupled protein receptor known as muscarinic receptors, allowing for a parasympathetic reaction in the cardiovascular system (where these receptors are expressed), and thereby decreasing cardiac output by inhibiting heart rate. During rest, PNS predominates and controls the heart rate at a resting rate of 65-80 beats/minute (bpm), if parasympathetic nerves to the heart are cut, then the heart beats at its own rate of about 100 bpm.
The numbers of each genotype of mice in the questions above shows that there are more dark mice living on the dark substrate and more light mice living on the light colored substrate. But when we consider comparative overall fitness for the entire area, which fur color seems to have the greatest overall selective advantage, and why
Answer:
Dark colour.
Explanation:
Dark fur color seems to have the greatest selective advantage because of their hard physical body which occurs due to extreme environmental conditions. The dark colour of mice occurs due to the high intensity of sunlight which increases melanin in their skin. These dark colour mice pass through a very hard and extreme environmental conditions so that's why Dark fur color seems to have the greatest selective advantage.

Noah wants to show the largest source of carbon on Earth for his school project. According to his research, most of the carbon on Earth is stored in the form of
.
Answer:
The majority of carbon on Earth is found in rocks and sediments, with the remainder found in the ocean, atmosphere, and living creatures. Carbon cycles pass through these reservoirs, or sinks.
Explanation:
For his school project, Noah wants to demonstrate the earth's natural primary carbon-producing source. His results suggest that sedimentary rocks are where the majority of the carbon on earth is preserved for future use.
What is sedimentary rock?The gradually building or deposition of mineral or organic particles at the Earth's surface, followed by cementation, is the process by which sedimentary rocks are formed. Sedimentation is the broad term employed to define the procedures which lead to the accumulation of these particles.
Sedimentary rocks are constructed from pre-existing rocks or remnants of extinct creatures. They emerge from deposits that amass on the Earth's surface. Apparent bedding or layering is particularly common in sedimentary rocks.
Thus, his results suggest that sedimentary rocks are where the majority of the carbon on earth is preserved for future use.

6.Two apparently normal parents have a daughter who suffers from agammaglobulinemia (AGG), an inherited defect of the immune system. Use a Punnett square to show how two normal parents could have a child afflicted with an inherited disease. What are the parents' genotypes
Answer:
See the answer below
Explanation:
For two normal parents to have produced a daughter who suffers from AGG, it means the disorder is an autosomal recessive trait. In order words, it means the parents are both carrying the allele for the disorder in recessive form.
Let us assume that the allele for the disorder is represented by b, meaning that the alternate form would be B. Both parents will have the genotype Bb and will both appear normal.
Bb x Bb
BB Bb Bb bb
The affected child would be the one with bb genotype while the remaining children would appear normal. See the attached image for the Punnet's square analysis of the cross.
The genotypes of the parent would be heterozygous.
As with most fluid samples sent for microbiological analysis, Mandy starts her investigation with a Gram stain.
Gram Stain Analysis Classify the infectious agent based on the Gram staining.
Hi. Unfortunately your question is incomplete and you have not shown any photos of the sample that Mandy must identify by Gram stain. However, after researching her question on the internet, I was able to find another question exactly like this one, which showed the microorganism that should be analyzed. This image is attached below. In that case, I hope the answer below can help you.
Answer:
Gram-positive cocci
Explanation:
It is possible to identify that the microorganism presented is a bacteria due to the application of the test known as Gram stain, which allows the identification of gram positive and gram negative bacteria. This test allows the bacteria to be subjected to a specific dye that reacts with the chemical composition of the bacteria, modifying its color. Gram positive bacteria show a blue color after the test, while gram negative bacteria show a red color after the test.
As we can see in the attached image, the bacteria that Mandy is analyzing shows a blue color, after being submitted to Gram stain, being then a gram positive bacteria.
We can also see that the colonies of this bacterium have formed round, similar to a coconut and for this reason, we can conclude that the bacterium has the shape known as cocci.
Therefore, we can classify the microorganism as a Gram-positive cocci.
