Answer: Absorb water
Explanation: i took the quiz the other guy is wrong
Absorbing the water from soil is function of root and not a stem. Thus, option B is correct.
What is stem?The structural part of plant, that supports leaves, flowers, and fruits is called as stem. Stems are frequently differentiated for storage, asexual reproduction, protection, or photosynthesis.
The stem is divided into nodes and internodes. Node consist of buds and leaves, that can grow into the branches. It also gives rise to adventitious roots. The function of internode is to distance one node from another.
Stem supports and uprights leaves, flowers and fruits. The stem keeps the leaves in the light and provides the plant with a place to hold the flowers and fruit. It transports fluid between xylem and phloem roots and shoots. Therefore, transportation of water and nutrients is the function of stem, and not absorption. Hence, option B is correct.

Choose one of the following scenarios and answer the questions provided. Support your answers using scientific reasoning and discussing possible impacts to individuals, society, and the environment. Be sure to also discuss any medical or ethical issues that may apply. (10 points)
Scenario 1:
Genetic engineering can be used to create more productive strains of farm animals. By adding genes to an animal's DNA, the animal can be made to produce milk or meat containing vital nutrients that would not be found naturally in those products. This provides a greater amount of nutrients per serving of milk or meat.
Do you think that this type of genetic engineering should be pursued? Explain your answer. (5 points)
What are some possible impacts (positive and negative) of this type of genetic engineering on individuals, society, and the environment? (5 points)
Scenario 2:
In the future, doctors may be able to evaluate your DNA to check for genetic markers related to specific medical conditions or harmful reactions to medications. Your personalized genetic profile could be kept on record and referred to in order to develop personal medical treatment based on your unique DNA sequencing. Scientists have found that just small variations in a specific section of your DNA can help determine how well some medications can work for you or if they would be beneficial at all.
Would you want to have your DNA profile kept in your medical record as a reference for your doctors? Explain your answer. (2 points)
What are potential pros and cons of having such tests done and referring to DNA sequences when determining a patient's medical treatment? (5 points)
Describe how the availability of this technology might affect the frequency of genetic diseases in individuals and populations. (3 points)
Answer:
1. It should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. There are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but I can't think of an example where the fears didn't turn out to be baseless.
2. Yes. First, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. The pros involve better medical treatment. The cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. Looking at DNA markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. And OK, actually I suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency.

Which of the following is the reason in how the anterior pituitary differs from the
posterior pituitary?
O A) the hypothalamus controls the release of posterior pituitary hormones but not the anterior
pituitary
B) the anterior pituitary makes its own hormones; the posterior pituitary releases hypothalamic
hormones
C) the posterior pituitary works independently of the hypothalamus
D) the anterior stores hormones produced by the posterior pituitary
Answer:
B) the anterior pituitary makes its own hormones; the posterior pituitary releases hypothalamic hormones
Explanation:
The pituitary gland is referred to as "master gland" because it coordinates the activities of other endocrine glands. The pituitary gland is composed of two lobes namely: anterior pituitary and posterior pituitary. These two lobes are individually controlled to release several hormones by the HYPOTHALAMUS.
However, one major difference between the anterior and posterior pituitary lobe is that; the posterior pituitary DOES NOT MAKE ITS OWN hormone, hence, releases the hormones (oxytocin and ADH) it stores but produced by the HYPOTHALAMUS. On the other hand, the anterior pituitary PRODUCES ITS OWN hormones but waits for hypothalamic signal to release them.

Answer: what does the question say i cant see the attachment?
Explanation:
Answer: 3. anticodon, 4. amino acid, 5. In stage one, glucose is broken down in the cytoplasm of the cell in a process called glycolysis. 6. The process of gene expression involves two main stages: Transcription: the production of messenger RNA (mRNA) by the enzyme RNA polymerase, and the processing of the resulting mRNA molecule. 7. 64. 8. One codon, AUG, specifies the amino acid methionine and also acts as a start codon to signal the start of protein construction. There are three more codons that do not specify amino acids. These stop codons, UAA, UAG, and UGA, tell the cell when a polypeptide is complete. 9. In the process of translation, the mRNA attaches to a ribosome. Next, tRNA molecules shuttle the appropriate amino acids to the ribosome, one-by-one, coded by sequential triplet codons on the mRNA, until the protein is fully synthesized. When completed, the mRNA detaches from the ribosome, and the protein is released. plzz mark brainliest
Explanation:
1. Predict: How do you expect the spread of a foodborne disease to be similar to and different
from the spread of a person-to-person disease?
PLEASE ANSWER
Answer and Explanation:
The transmission of diseases through food and through people to people, are similar because both are caused by human contact with infectious parasitic agents such as bacteria and viruses. However, it is possible to notice some differences between these two types of transmissions.
Transmission of disease through food occurs when an individual eats contaminated food or drinks contaminated liquid. This contamination occurs due to the lack of hygiene of the handlers and storage problems, which can allow microorganisms, mostly bacteria, to grow in the food. Thus, when the contaminated food is ingested, the microorganisms will release toxins in the stomach that will cause disease. In the case of water, contamination can also happen due to the lack of basic sanitation and the incorrect dumping of garbage and human waste.
Diseases transmitted from person to person can occur in many different ways. One of the best known ways is through the contact of a healthy person with salivary goths or other body fluids of a person with the disease. However, this transmission can also occur through the contact of a healthy individual with the feces of a sick individual and even with physical contact with a sick individual.

Which of the following best describe gas particles?
SELECT ALL THAT APPLY
a moving randomly
b collide into each other
Cmove slow
d high kinetic energy
moving orderly
e moving orderly
Answer:
a, b, d (see below)
Explanation:
So, looking at the 3 states of matter:
Solid - holds a shape and is made up of particles that vibrate in place (because particles are always moving no matter what)
Liquid - holds shape of its container and has particles with some space in between them that allow them to flow
Gas - holds shape of its container and has particles with huge gaps of space between them that are always, constantly moving and zooming around
Refer to the image below for a better visual understanding.
So, now, looking at the answer choices:
a) moving randomly
Yes. They are—they're speeding around super fast all the time.
Every time heat is added to something, the particles start loosening up and moving. A lot.
So when you add heat to a solid, it starts loosening up and moving around until it becomes flowy enough to be a liquid. Then, if more heat is added, the particles moving faster and loosen up even more until they're a gas.
Imagine doing that one more time, and you'll have plasma. As you may have guessed it, plasma moves super fast
b) collide into each other
Yes. Because they're moving so fast and uncontrollably all the time, they're bound to have rammed into one another a few or more times.
Imagine bumper cars at a carnival, except the speed of each car is sooo fast that you could be on a highway. You're probably going to hit someone, which is why bumper cars are not that fast in reality. For safety reasons.
c) move slow
No. Since we know that they're always zooming around (refer to my bumper car example above, in bold), they obviously can't be slow.
d) high kinetic energy
Yes. Anything moving (a.k.a. in motion) has kinetic energy. If gases zoom super fast 24/7, they will have high kinetic energy.
Having high kinetic energy means that the something is moving really fast or a lot. In this case, gases are both.
e) moving orderly
No. They're moving everywhere and really fast, so they have no control over how they move because of how fast they are.
(refer to my bumper car example in answer b, in bold)

What might happen to the Earth if human increase the amount of greenhouse gasses?
Explain your answer.''
Answer:
Global warming will occur
Explanation:
Greenhouse gases are special gaseous compounds that have this ability to trap HEAT due to their structural composition. They include; carbon dioxide (CO2), chlorofluorocarbons (CFC), methane (CH4) etc.
Anthropogenic activities such as burning of fossil fuels etc. release these gases into the atmosphere where they cause harm to the Earth. Greenhouse gases contribute immensely to the GLOBAL WARMING EFFECT, which is the increase in the temperature of the Earth surface. Therefore, if humans increase the amount of greenhouse gases in the atmosphere via their actions, there will be a GLOBAL WARMING occurrence.

Wave frequency is measured in units
called Hertz (Hz). One Hertz is defined as
one wave per second. Suppose a person
counted 10 waves passing by over a time
period of 1 second. What is the wave
frequency?
Answer:
it will be 10Hz ,because number of waves per second is 10 so we divide with 1second
The wave frequency of a wave which is passing by 10 waves over a time period of 1 second will be 10 Hertz (Hz).
What is Wave frequency?
Wave frequency can be defined as the number of waves which are passing through a fixed point in a given amount of time period. The SI unit for the wave frequency is the hertz (Hz), where 1 hertz is equal to 1 wave which is passing through a fixed point in the time period of 1 second. A higher-frequency wave has generally more energy than a lower-frequency wave with the same magnitude of amplitude.
The wave frequency of a wave which is counted to be 10 waves passing through a point in a time period of 1 second will be 10 Hertz (Hz).

which of the following events does not occur in spermatogenesis
Answer:
The mitochondria and Golgi apparatus are packaged into the head of the sperm.
Explanation:
Spermatogenesis is the production of male germ cells. Sufficient stimulation with sex hormones, especially testosterone, and a lower temperature, which is achieved by placing the testicles in the scrotum, are required for the correct course of spermatogenesis. Sperm production has three phases: reproductive, growth and maturation. At the beginning of sperm development are spermatogonia, which are male primordial cells. They have a spherical shape and are located at the edges of the seminal canals. Spermatogonia is mitotically divided. On the one hand, in order to preserve their numbers, and on the other hand, their division produces primary spermatocytes, which lie above the layer of spermatogonia. Primary spermatocytes are diploid, but after the first meiotic division, haploid secondary spermatocytes are formed from them. They still have double chromatids, so a second meiotic division soon occurs, the product of which is spermatids. Spermatids are already fully haploid and do not divide further. Spermatids then undergo a process of spermiogenesis, in which the nucleus condenses, forming a flagellum and losing most of the cytoplasm and some organelles. Immature sperm travel through the seed-forming canals to the epididymis, where they are definitively matured. This whole process takes about 72 days.

Explanation:
eselson and Stahl relied on equilibrium density gradient centrifugation to resolve the DNA containing 14N from the DNA containing 15N.They started off with DNA in media containing the heavy isotope, then switched to media containing the lighter isotope and allowed DNA replication to take place. Under semiconservative model of DNA replication, after THREE rounds of replication, how many bands of DNA would you see and which band would contain more DNA molecules
Answer:
The correct answer would be - two bands ( one intermediate, and one light)- the light band contains more DNA molecules.
Explanation:
After the switching to the lighter isotope by the second round of replication where light strands are used as template strands, produces the light band of 14N.
After three rounds of semiconservative replication, where template strand contains both heavy and new formed light bands or nitrogen and produces so in a Density gradient, there will be 2 bands one light band and the other intermediate band.
