does the gut flora affect digestion?

Answers

Answer:

Yes.

Explanation:

Our bodies need different organs to regulate our bodily functions, and the gut is no different. The gut flora helps us digest and break down the food we eat, along with producing various enzymes that help to break down carbohydrates. Also, after the carbohydrates are broken down, they can pass through the gut wall into the blood (just a little fun fact). The gut also helps to benefit our immune system. One last bit of information is that an imbalance of bacteria and microbes in our bodies may lead to weight gain, high blood sugar, high cholesterol, and many other terrible issues.

When Linnaeus began classifying organisms in the 1700s, he categorized them as plant, animal, or mineral. These kingdoms were later revised to exclude minerals and expanded to include animals, plants, fungi, protists, and bacteria. Which of the following best explains a reason for this change? (2 points)

Group of answer choices

As new organisms were discovered, new kingdoms were created to sort them based on ability to interbreed.

It was discovered that the organisms in each of the five kingdoms have a different method of obtaining nutrients and are therefore fundamentally different.

Technological advances led to the discovery of single-celled organisms and increased our understanding of relationships between organisms.

Genetic research led to the discovery that each of these five kingdoms has a unique evolutionary ancestor.

Which statement about inheritance is true?
Girls get most of their traits from their moms; boys get most of their traits from their dads.
Male offspring will always have an X-linked genetic disease if the mom is a carrier.
Fathers always determine the gender of the offspring in humans.
Males never have Y chromosomes.

Answers

Answer:

The correct answer is the third statement.

Explanation:

In humans, the males possess one X and one Y chromosome, while the females possess two X chromosomes. Thus, the female always donates X chromosome to the gamete. In any case, the female always generates a similar kind of gamete. While the male either pass X or the Y chromosome to the progeny.  

When the gamete with the X chromosome combines with the female gamete than the offspring would possess XX chromosomes and will be a female. On the other hand, when the gamete comprising the Y chromosome combines with the female gamete than the offspring would possess the XY chromosome and will be a male. Thus, it is the father who determines the gender of the offspring.

Wrong answersGirls get most of their traits from their moms; boys get most of their traits from their dads.

This is wrong. Parents gender does not affect traits passed on.

Males never have Y chromosomes.

This is wrong, Males have to have a Y chromosome. (XY)

Male offspring will always have an X-linked genetic disease if the mom is a carrier.

This is wrong. The male offspring have a 50/50 chance if the mother is a carrier, if she has the deseace than all the sons will have the decease.

Correct answerFathers always determine the gender of the offspring in humans.

This is because the mom is XX and the dad is XY. The mom gives the X in the gene, and the dad gives the X for daughters (X,X) and gives the sons a Y (X,Y) Males are always XY.

If the mom is a carrier, h,  then it will get passed down  50% of the time, and when it gets passed down to the males, they wiill have the deseace. If the mom passes the deacease down to the daughters, 50% will be a carrier too if the dad does not have the deseace. If the dad has the deacease, than 50% of the daughters will have the deacease, and the other 50% will be carrier, and still, 50% of the sons will have the deacease, while the other 50% will be completely clean. So in total 25% of the offspring will be a carrier, 50% will have the deacease, and the other 25% will not have the deacease or be a carrier.  

In Osmosis, a cell becomes turgid when it:
A. expands from absorbing too much water.
B. bursts from absorbing too much water.
C. bursts from absorbing too much water.
D. contracts from absorbing too much water.

Answers

Answer:

A

Explanation:

This occurs when a plant cell is placed in a hypotonic solution.A solution were the external solution concentration is less than the internal concentration of the cell, causing water to rush into the cell.

During osmosis by absorbing too much water from outside the cell, a cell becomes turgid. The correct option is A.

What is osmosis?

Osmosis is the passage of water molecules via a cell's partially permeable membrane from a solution with a large concentration of water molecules to a solution with a lower concentration of water molecules.

Osmosis occurs when the concentration gradient of water reaches zero or when the water's hydrostatic pressure equals the osmotic pressure.

Endosmosis and exosmosis are the two main types of osmosis that occur when water moves across the cell membrane. When cells are placed in a hypotonic solution, endosmosis occurs, which is the movement of water into the cell.

When cells are placed in a hypotonic solution, exosmosis occurs, which is the movement of water out of the cell.

Thus, the correct option is A.

Which factor plays a central role in determining which of the brain's synapses will be eliminated and which will be maintained?

Answers

Answer:

The answer is "frequency with which they are activated".

Explanation:

Frequency refers to the number of consecutive repetitive events per unit time. It is measured in hertz (Hz), equivalent to a single event per second. The time is the number of one cycle in a recurrent event, and so the duration is the same for the frequency, hence the frequency at which they are triggered is a key determinant of the brain's connections to be eliminated and maintained.

Cigarette smoke contains carbon monoxide. Explain how this
would affect the normal functioning of red blood cells in a person who
smokes cigarettes.

Answers

Answer: Carbon Monoxide is a very harmful and toxic gas which is formed from incomplete combustion of carbon.

Explanation: red blood cells contain haemoglobin ,which are responsible for carrying oxygen into our body system. So oxygen combines with haemagoblin to form oxyhaemogoblin in the red blood cells .

so if a person starts to intake cigarettes which contain high amounts of carbon monoxide ,it reduces oxyhaemogoblin formation because it binds very tightly to the haemogoblin .then carboxyhaemogoblin is formed and its permanent so causing reduction in aerobic respiration, and reduction in oxygen transport and causing damages to heart muscles.

Microorganisms are classified as bacteria, fungi, protozoa and algae. Viruses are
not explicitly categorized as microorganisms. Give reason.

Answers

Answer:

Yes

Explanation:

Because they have both living and non living characteristics so it is hard to classify them as they posses living characteristics as reproduction and others when inside the host and posses non living characteristics when outside the host

In microorganisms micro means small and organism means living ones, so those living ones which are not seen without the help of a microscope, are microorganism.

What are viruses?

Viruses are obligate parasites and are very small in size. Viruses cannot live outside the host cells as they require host cell gene expression machinery to divide and perform metabolic reactions. Viruses remain inactive in the environment until found the host cells.

As viruses cannot qualify the criteria of living beings because they cannot survive separately in the evnironment,  that's why cannot be considered living organisms.

Mostly microorganisms are single-celled organisms like bacteria, fungi, and protozoa. Viruses are not considered microorganisms because they are nonliving outside the host body.

Which wound usually involves ears, fingers, and hands, and results in tearing or pulling off of a flap of skin

Answers

Answer:

Avulsion.

Explanation:

Human bite wounds are blunt wounds, sometimes with partial or total avulsion (ear, lips, nose, hands) and with intense contamination. An avulsion is a complete tear of the skin and subcutaneous tissue. It does not allow the approximation of edges. It presents moderate to abundant hemorrhage and is accompanied by the exposure of underlying tissues (bone, tendon). The tear can be complete or partial; in the latter case, a connection or bridge is preserved between the torn tissue and the rest of the body.

You are examining the data from two time points taken in an experiment. At time 1 there was an extracellular concentration of Na of 115 mM outside the cell and 8mM inside the cell. An amino acid, lycine, is at 20mM outside and 40mM inside. At the second time measured Na is 100mM outside the cell and 23 mM inside the cell. Lycine is 15 mM outside the cell and 45mM inside. What is the best explanation

Answers

Answer:

See the answer below

Explanation:

The best explanation would be that both Na and the amino acid lycine are simultaneously diffusing (in bound form) from the outside to the inside of the cell.  

Considering the Na alone, one would see that the concentration outside the cell decreased in equal amount (15 mM) as the increase in the intracellular concentration of the same molecule.

Also considering the amino acid alone, the extracellular concentration increased by the same magnitude (5 mM) as the decrease in the intracellular concentration of the same molecule.

Hence, it could only be that both molecules bind together and diffused from the region of higher concentration (outside of the cell) to the region of lower concentration (inside).

Water is denser than isopropanol, so the water layer will always be below the isopropanol layer if they are both in the same container. What does this tell you about the make-up of the pigments for each specimen?

Answers

Answer:

One is polar and the other is non-polar.

Explanation:

The makeup of both water and isopropanol is different from each other due to their polar nature. Water is a polar substance means that it makes poles i.e. positive or negative while on the other hand, isopropanol is non-polar substance so due to this reason water and isopropanol make different layers. If both are polar or nonpolar substances so they will able to mix with each other.

PLEASE HELP!!! Give two forms of evidence for evolution that can be found in the fossil record (where animals have changed from simple to more complex.)

Answers

Answer:

Forms of fossil records can inlude the carcasses of animals and the structure of plants. These records can compare the advancements of creatures over a long period of time.

Explanation:

The further an animal or plant is burried underneath the soil, it is most likely that it lived much longer ago than a layer above it. The theory of evolution suggests that animals are always changing and adapting to their surroundings. For instance, millions of years ago, a dog like mamal existed but over time they grew accustomed to the water, developing fins flippers and eventually developed features similar to what we expect in whales today.

Plants, on the other hand, may have been much larger than the size they are today due to the excess of oxygen present in the atmosphere. Therefore, when they are fossilized scientists can realize that plants have come a long way in the tree of evolution.
