Answer:
Missense mutations may have different effects
Explanation:
A missense mutation is a single base-pair nucleotide change that causes an amino acid substitution in the resulting protein chain. A missense mutation may have distinct effects depending on the amino acid that is replaced in the mutated protein. For example, it is expected that the substitution between similar amino acid residues (such as, for example, leucine and isoleucine) may have no effect, while the replacement of one amino acid with another amino acid with different properties/charges/functional groups may render the protein nonfunctional. Similarly, it is expected that missense mutations localized at different exons/gene regions render different functional effects on the resulting protein isoforms.

the most common source of osteomyelitis is an infection that migrates via the bloodstream. direct invasion from a fracture. surgical contamination. a joint prosthesis.
Answer:
The correct answer is ''an infection that migrates via the bloodstream.''
Explanation:
An infection is the invasion of pathogenic germs or microorganisms that reproduce and multiply in the body causing disease. Bones, like any other organ or tissue in the human body, can become infected. Osteomyelitis is a bone infection caused by bacteria, mainly Staphylococcus aureus, although in some cases it can also be caused by fungi. The infection can start in another part of the body and spread to the bone through the bloodstream. In this case, it usually occurs at the ends of the leg and arm bones in children and in the spinal column (vertebrae) in adults, especially the elderly.
Sodium and potassium ion channels have several negatively charged residues at the entry to the channel. Identify the bases on which K channels specifically select for K ions, in other words, why do K channels not enable Na ions to cross the membrane
Answer:
Mechanism in attachment.
Explanation:
K⁺ channels have narrow pores, which prevents the passage of larger ions. However, since Na⁺ has an ionic radius smaller than K⁺, this does not explain the selective permeability of these channels towards K⁺.
In this case, the channel pore has a narrow selective filter which is delimited by the backbone carbonyl oxygens (C=O). When a K⁺ ion enters in the selection filter it interacts with these oxygens, and the molecules of water bound to K⁺ are displaced, which allows the passage of the dehydrated ion K⁺ through the pore. However, a dehydrated Na⁺ is too small to interact with these carbonyl oxygens in the selective filter, which stays open. As a consequence, the Na⁺ ion remains bonded to the water molecules in a hydrated complex that is too big to pass through the channel.

The absorptive effectiveness of the small intestine is enhanced by increasing the surface area of the mucosal lining. Which of the following accomplish this task?
a. the rugae and haustra
b. plicae circulares, villi, and microvilli
c. the vast array of digestive enzymes
d. Brunner's glands and Peyer Patches
Answer:
Option B
The plicae circulares, villi, and microvilli
Explanation:
The plicae circulares are the folds of mucous membrane on the inside of the small intestine. They are covered with tiny hair-like structures called the villi, and microvilli. The purpose of those folds is to increase the surface area for the absorption of food nutrients to take place in the small intestine before the food finally moves on to the large intestine for excretion.
The tiny hair-like projections (villi, and microvilli) further increase the surface area available for nutrient absorption by providing extra surfaces in which the nutrients can diffuse into the small intestine through.
This makes option B correct.

How many genetically different kinds of sperm could be produced by a Drosophila melanogaster male (XY)
Answer:
The correct answer is - 16 genetically different kinds of sperm could be produced by a Drosophila melanogaster male (XY).
Explanation:
There are four pairs of chromosome in Drosophila melanogaster. In this species homologous chromosomes pair and segregate but do not follow recombination or crossing over. Each chromosome has two alleles or copies so as we know there are four pairs of chromosomes, then total number of chromosome copies would be 8, then
number of different combinations = 2^n (n = number of homologous pairs
)
2^n
= 2^4
= 16
Thus, the correct answer would be : 16.

1.) You decide to clean the bathroom. You notice that the shower is covered in a strange green slime. You decide to try to get rid of this slime by adding lemonade juice. You spray half of the shower with lemonade juice and spray the other half of the shower with water. After 3 days of “treatment”, there is no change in the appearance of the green slime on either side of the shower.
Independent Variable:
Dependent Variable:
Control:
Conclusion:
Answer:
The correct answer is :
Independent Variable: side of the shower with lemon juice
Dependent Variable: cleanliness of shower
Control: spray of water
Conclusion: lemonade juice have no effect on slime
Explanation:
Independent variable in any experiment is the variable that is changed or manipulated as here side of the shower that is sprayed with lemonade juice is manipulated to see if there is any effect on the cleanliness of shower.
Dependent variable is the variable that is observed or measured to check if manipulated variable or independent variable have any effect on it, like the cleanliness is measured to check if lemonade juice clean the slime of the side or not.
The control is something that remains the same to check the condition or effect that is not changed or can be compared to it. Water spray is control in this case.
The conclusion of this experiment is that there is no effect of lemonade juice on the cleanliness of slime present in the shower
In any experiment, an independent variable is the variable that is altered or manipulated, such as the side of the shower that is sprayed with lemonade juice to determine if it has any influence just on cleanliness of the shower.
This dependent variable is a variable that can measure Lemonade a manipulated variable or independent variable has any effect on it, such as whether lemonade juice cleans the slime off of the side or not.
A control is something that remains unchanged to assess the condition or impact which has not changed or may be contrasted to it. In the this scenario, the water spray is under command.
The experiment concludes drinking lemonade seems to not influence the cleaning of slime inside the shower.
Each side of the shower with lemon juice is an independent variable.Shower cleanliness is a variable.A water spray can be used to keep things under control.In conclusion, lemonade juice does not affect slime.Learn more:

Answer:
piriformis muscle is below the gluteus maximus
The gluteus maximus is located superior to the gastrocnemius muscle.
The gluteus maximus is the most superficial gluteal muscle and the main extensor muscle of the hip. The group of the gluteal muscles includes the gluteus maximus, gluteus medius, gluteus minimus and tensor fasciae latae. The gluteus maximus is a thick muscle that has a quadrangular shape. It is responsible for the maintenance of keeping the upper body erect.The gastrocnemius muscle, also known as leg triceps, is an important muscle that is required for walking and running. This muscle is located on the back portion of the lower leg. The tendon of the gastrocnemius muscle is joined with the tendon of the soleus muscle and both form the Achilles tendon and attach to the calcaneus (i.e., the heel bone).Learn more in:

In a certain breed of plants, dark green is determined by the dominant gene 'G' and light green is determined by the recessive gene 'g'. The heterozygotes show 75% penetrance. If the parental cross GG x gg was made, how many of each of the expected phenotypes will be observed in a population of 400 F2 plants
Answer:
The answer is 300.
Explanation:
When we cross GG and gg, 100% of the offspring will be heterozygous. If the heterozygotes show 75% penetrance meaning that there is a 75% probability that the plant that has the G gene will actually show it in it's phenotype.
So that means that 75% of the offspring should have dark green color, which means that 300 plants will have the expected phenotype and 100 will not.

PLEASE HELP ME!!!! This figure shows two alleles for the beta-globin gene. The A allele is the most common allele. The S allele is responsible for Sickle Cell Disease. The R group glutamic acid is negatively charged, while the R group of valine is hydrophobic. What molecular change, ultimately resulting in the sickle cell phenotype, occurs when valine in substituted in place of glutamic acid at position 6 in the β subunit of hemoglobin?
Answer:
The correct answer is option B. The tertiary structure of the beta subunit changes, exposing a hydrophobic cleft which allows hemoglobin to form long chains in RBC.
Explanation:
As it is clearly mention as there is point mutation that leads to single nucleotide change which results in to valine instead of glutamate. Valine is hydrophobic in nature not like glutamate. Valine aggregate and makes a rigid structure of molecules.
Due to this rigid molecule of valine aggregates, RBCs form a crescent or sickle like shape due to the higher viscosity and low solubility of Mutated hemoglobin in deoxy condition. It leads to formation of polymer that blocks the vessels.
Thus, the correct answer is option B.
Gregor Mendel demonstrated that traits are passed from parents to offspring independently of one another under all circumstances that he tested. All other genetics researchers have observed this as well. Based on this information, the statement can be made that “traits are passed from parents to offspring independently of one another.” Which describes the statement of fact? a law a hypothesis a theory an observation
The answer is A. A law
Explanation:
The fact "traits are passed from parents to offspring" has been scientifically proven not only by Mendel but by many other scientists. Additionally, these experiments showed this phenomenon always occurs. In this context, this statement is considered a law, which is a statement that describes an event or phenomenon that always happens and has been proven through experiments. Moreover, this is classified as a law rather than a theory because it only describes a phenomenon of genetics but does not explain it.

Lasix is a diuretic that blocks the reabsorption of sodium in the ascending loop of Henle. The result of giving this drug would be
Answer:
Reduced extracellular fluids within the kidney, reduced blood pressure.
Explanation:
The loop of henle, which are located within the nephrons in the kidney, have a task of acquiring the water and NaCl from the blood and keeping enough of it in the body so that the homeostasis is maintained.
The result of giving Lasix that reduces the amount of NaCl reabsorption would first of all be "reduced extracellular fluids within the kidney" and it would also change the pH level of the blood and drop blood pressure levels.

How do tiny atoms bond together to form bigger substances , and how are these substances important for life ?
Answer:
The detailed answer to this question is found in the explanation section.
Explanation:
Life is generally made up of matter, which is referred to as anything that has mass and occupies space. Matter is composed of elements such as carbon, hydrogen, oxygen etc, which in turn constitutes the smallest indivisible unit of an element called ATOMS.
Atoms are chemically bonded together to make up the elements in molecules and compounds. These compounds and substances are contained in the basic unit of life called CELLS, which play a pivotal part in the sustenance of life. For example, the enzymes and hormones that bring about physiological responses in our body are made up of protein molecules. These protein molecules are similarly composed of chemical elements such as carbon, oxygen, hydrogen, nitrogen etc, whose building blocks are atoms.
In a nutshell, all LIFE characteristics are made up of matter which possess atomic particles that are chemically bonded together to form substances that hold life together.

Earth's Greatest Enemies?Climatologist James Lovelock(originator of theGaia_hypothesis ) once said that Earth's greatest enemies were cars, cows and chainsaws because of their contributions to destabilizing planetary climate.1. How do each of these things (cars, cows, andchainsaws) contribute to the destabilizing of Earth's atmosphere and climate? You must cite specificevidence from any Unit of the course to support your response. And...2. How are these three things connected to one another either by cause, effect or by solution. Consider all of the environmental concerns you have been learning about during the entire course and describe how these 3Cs as a group relate to one specific environmental issue (other than atmospheric destabilization).Reminder: Loss of land plants will not result in a reduction of atmospheric oxygen (because most of planetary photosynthesis and its resulting oxygen production is in the oceans).
Cars, cows and chainsaws are major polluters and their use must be regulated and limited, to reduce the emission of polluting gases into the atmosphere that can cause drastic climatic changes that harm the environment that we know intensely.
Although it is not widely publicized in the media and few people know about it, the chainsaw is a great villain of the earth's atmosphere, since its use releases large amounts of CO2 into the atmosphere, due to the burning of gasoline that these machines make to work. CO2, in addition to endangering the operator's life, is a gas that destroys the ozone layer and increases the effect of global warming. Not only does the chainsaw release this gas, but so do cars, which reinforces the need to use renewable fuels to be used in both cases.
Cows also release polluting gas, methane, which has a greater polluting potential than CO2. Methane is the result of the cow's digestive reactions, which release this gas into the atmosphere steadily. As herds of cows tend to be large, livestock becomes a major polluter, as herds result in a strong release of methane into the environment. This reinforces the need for increasingly stronger regulations for livestock, in addition to highlighting the importance of adopting alternative methods of feeding that reduce meat intake.
