Which of the following statements is true? Stem cells can only be obtained by destroying embryos. Stem cells can be obtained from the brain and other tissues in healthy adults. Stem cells are unobtainable because they can't be kept alive in lab conditions. Stem cells can be produced artificially.
Answer:
Stem cells can be obtained from the brain and other tissues in healthy adults.
Explanation:
Now research is showing that these stem cells can actually be obtained throughout the brain or other body tissues.
Stem cells can be obtained from the brain and other tissues of healthy adults by a mechanism of induced pluripotent stem cell (IPSC). The second statement is the correct one.
What is a stem cell?
Stem cells are present in the body and can form either a single type of cell or multiple kinds of cells. The zygote is an example of a stem cell because it divides to form various types of cells such as the heart cell, lung cell, nerve cell, and so on. This is called a totipotent stem cell, which can form all types of cells.
As the embryo grows, the totipotent nature of cells is lost, and they become pluripotent. Pluripotent stem cells can differentiate to form a wide range of organs such as the lungs, heart, etc.
These cells are further specified as being multipotent stem cells. These stem cells can only form a particular range of cells, such as hematopoietic stem cells. This stem cell can only form blood cells.
A mature cell from the body can be taken and chemically induced to be a pluripotent stem cell (IPSC). Stem cells can't completely form in a lab as they require a lot of signalling molecules.
Hence, stem cells can be obtained from the brain and other tissues of a healthy adult.

Explanation:
The chemical equation of photosynthesis includes 602. Which best describes this substance?
a solid used during photosynthesis.
a gas used during photosynthesis.
a liquid produced during photosynthesis.
a gas produced during photosynthesis.
Answer:
The correct option is;
A gas produced during photosynthesis
Explanation:
The chemical reaction of photosynthesis is given as follows;
6CO₂(g) + 6H₂O(l) + Energy from light → C₆H₁₂O₆(s) + 6O₂(g)
Therefore, six molecules of gaseous carbon dioxide (CO₂) combine withe six molecules of liquid water (H₂O) in the presence of energy from Sunlight to produce one molecule of solid glucose (C₆H₁₂O₆) and six molecules of gaseous oxygen (O₂)
The 6O₂ is the gaseous oxygen produced as a byproduct of photosynthesis
Answer:
D
Explanation:
In response to high amounts of phosphate transport into the cell: a. PhoR is phosphorylated by the phosphate transporter protein Pst b. PhoR binds with PhoB to remove PhoB repression of phosphate regulon genes c. PhoR is exported out of the cell to scavenge phosphate molecules d. PhoU changes conformation to allow PhoR to autophosphorylate e. PhoU keeps PhoR bound to the phosphate transporter protein Pst
Answer:
e. PhoU keeps PhoR bound to the phosphate transporter protein Pst
Explanation:
PhoU is a membrane protein known to regulate the transport of phosphate (Pi) between cellular compartments. It has been discovered that mutations in this protein cause lethality because the cell becomes incapable of controlling the intracellular levels of Pi, this being toxic for the cell. PhoR is a histidine kinase/phosphatase. When the Pi level is considered to be a limiting factor, PhoR autophosphorylates at a histidine residue and then donates its phosphoryl group to PhoB. On the other hand, when the Pi level is high, this protein removes the phosphoryl group from phospho-PhoB. Finally, the Pst is a signal transduction protein that acts as a transporter capable of switching its conformation during the transport of PI.

how did autotroph and heterotroph lead to a two kingdom classification system
Answer:Autotrophs are organisms that can produce their own food from the substances available in their surroundings using light (photosynthesis) or chemical energy (chemosynthesis). Heterotrophs cannot synthesize their own food and rely on other organisms — both plants and animals — for nutrition. Technically, the definition is that autotrophs obtain carbon from inorganic sources like carbon

In a species of chickens, incomplete dominance between alleles for black (B) and white(w) feathers
is observed. Heterozygotes are blue.
• If two blue chickens are crossed, what is the probability that the offspring will be blue.
Answer:
1/2
Explanation:
This question involves a single gene coding for feather color in chickens. The black allele (B) is incompletely dominant over the white allele (W). This means that the allele B will not mask the phenotypic expression of allele W, hence, a third intermediate blue phenotype (BW) will be produced.
According to the question, if two blue chickens are crossed i.e. BW × BW, the gametes B and W will be produced by each parent. Using these gametes in a punnet square (see attached image), the following offsprings will be produced:
BB, BW and WW in the ratio 1:2:1
BB is black, BW is blue, WW is white. Hence, the probability of producing a blue chicken from this cross is 1/2.

While you and your classmate are studying for your biological anthropology midterm, your classmate tells you that the bones of Lucy, a famous australopithecine specimen that dates to about 3.2 million years ago, were dated based on carbon-14 analysis. Why is this incorrect?
The options for this incomplete question are :
Fossils are living organisms that have wholly or partially been transformed into rock.
Lucy does not have bones with organic material necessary for carbon-14 dating.
This specimen is also far too old for C-14 dating to be accurate, as well as for any other technique but palaeomagnetic dating.
Your classmate is therefore incorrect for all of the reasons listed. (All of the above)
Answer:
The correct answer is - all of the above reasons.
Explanation:
Fossils are living life forms that have completely or mostly been changed into the rock during the process of fossilization. Lucy doesn't have bones with organic material that are essential to use the carbon 14 dating technique.
This example is additionally very old for C-14 dating to be exact, just as for some other method, however, palaeomagnetic dating can do the job of dating in this case.
Thus, the correct answer is - all of the above reasons.
Which is the first step that geologists must do to compare rock layers at distant locations? 1.find the absolute age of rocks at both locations 2.compare a layer at one location to layers at other locations 3.identify index fossils in one or more layers at one location 4.collect fossils from different locations to study the organisms’ lifestyles
Answer:
2.compare a layer at one location to layers at other locations
Explanation:
Comparing rock layers in distant places can be a challenge for geologists since these layers may have different environmental factors that caused different transformations in them.
Therefore, when it is necessary to establish a comparison between layers of rocks in different ligands, geologists must establish steps to make an efficient comparison and have results consistent with reality. To do this, they must first compare a layer in one location with layers in other locations, assign relative age to a layer in one location, and identify index fossils in one or more layers in one location.
To compare rock layers at distant locations is geologist should ; Identify index fossils in one or more layers at one location ( 3 )
When geologists study rock layers at different locations they try to determine the ages of the rocks by studying the different layers from different locations. this task could be very challenging. therefore to make their study easy the first step geologists should take is to Identify index fossils in one or more layers at one location
Comparing layers at different locations can be use to estimate the relative ages of the rocks closer to reality but it a very daunting task.
Hence we can conclude that the first step that geologists must take to compare rock layers at distant locations is Identifying index fossils in one or more layers at one location

Together, the stages of cellular respiration break down one molecule of ___ to generate a total of ____ molecules of ATP. The remaining energy is released as __ .
Answer:
1) Glucose
2) 36
3) Heat
Explanation:
Cellular respiration is a metabolic process that every living organism undergo. It is the process by which energy is obtained by living cells. In the process of celluar respiration, energy-storing food molecule called Glucose is broken down in the presence of oxygen in order to release its energy and convert it to a usable form by the cell called ATP.
Celluar respiration occurs in three distinct stages in eukaryotes viz: Glycolysis Kreb's cycle and Oxidative phosphorylation. In Glycolysis, which occurs in the cytoplasm, glucose is broken down in a series of enzymatic reaction to yield Pyruvate and releasing a net gain of 2 ATP molecules. In Kreb's cycle, which occurs in the mitochondrion, produces carbondioxide in a two-cycled reaction involving Pyruvate. 2 ATPs are also produced in this stage.
Lastly, in Oxidative phosphorylation also occuring in the mitochondrion, electrons are passed through electron acceptors to create a pump that generates the synthesis of 32 ATP molecules. In general, the three stages yield a total of 36ATP molecules from one molecule of GLUCOSE.
The rest of the energy from the oxidation of glucose is lost as heat energy, which is responsible for the warming effect we feel.
The pathogenesis of tuberculosis includes the entrance of mycobacteria into the lungs and the resulting of which of the following? (Select all that apply.) Calcification Ghon tubercles Formation of granulomas Activation of macrophages Antigen-antibody complexes
Answer:
The macrophages have a in the calcification process, which generates the inflammatory processes. The Ghon tubercles is a lung lesion caused in tuberculosis that consists of a focus of calcification in conjunction with a lymph node infection. A granuloma is a mass of immune cells that forms when the immune system tries to isolate foreign substances.Macrophages can be activated by a variety of stimuli during the immune response. The antigen-antibody (Ag-Ac) reaction is one of the molecular reactions in the body's immune response.Explanation:
Tuberculosis is a disease caused by Mycobacterium tuberculosis, a bacterium that almost always affects the lungs. When the active form of the disease is present, symptoms (cough, fever, night sweats, weight loss, etc.) can be mild for many months. If not treated properly, Tuberculosis can be fatal.
Macrophages are a type of white blood cell found in the blood and they are the first body's defense against foreign substances. So they are effector cells of the immune system, the main players in the innate immune response.
When M. Tuberculosis infects a person, it attacks this first-response immune cells in the lungs, the macrophages. When they recognize these pathogens, macrophages produce the cytokines IL-1 and TNF-α, which cause the inflammation itself by acting on the endothelial cells of the nearby blood vessels to allow the transendothelial migration of the leukocytes. The inflammation t is a non-specific response to environmental aggressions, and its purpose is the isolation and destruction of the damaging agent, as well as repairing the damaged tissue or organ.
The macrophages have a in the calcification process, which generates the inflammatory processes. The Ghon tubercles is a lung lesion caused in tuberculosis that consists of a focus of calcification in conjunction with a lymph node infection. These lesions are especially common in children and may retain viable bacteria, so they are sources of disease transmission and may also be associated with classic tuberculosis reactivation after several years of inactivity.A granuloma is a roughly spherical mass of immune cells that forms when the immune system tries to isolate foreign substances that it has been unable to eliminate. Therefore it is a special type of inflammation that can occur in a wide variety of diseases. Infections that are characterized by granulomas include tuberculosis, but also include for example leprosy, histoplasmosis, cryptococcosis, coccidioidomycosis, blastomycosis, and cat scratch disease.Macrophages are usually in a resting state, they can be activated by a variety of stimuli during the immune response. Antigen phagocytosis serves as an initial stimulus; however, macrophages and their activity can be increased by cytokines secreted by, or through contact with, helper T-lymphocytes. One of the most powerful macrophage activators is gamma interferon. They are also able to recognize molecular patterns associated with pathogens. M. tuberculosis is a pathogen that contains Pathogen-associated molecular patterns (PAMPS), which are small sequences of molecules that repeat in groups of pathogens. They are recognised by Pattern-recognition receptors (PRRs), which include the Toll-like receptor (TLRs) family or the NOD-like receptors (NLRs). Once the receptors found in the macrophages recognize these PAMPS, the macrophages are activated are ready to perform an immune response.The antigen-antibody (Ag-Ac) reaction is one of the molecular reactions in the body's immune response. The concept refers to the specific binding of an antibody to an antigen to inhibit or delay its toxicity. When the macrophage recognizes a pathogen, it phagocytes it and degrades it, and presents its peptides to a T cell. This can activate a cytotoxic response, causing apoptosis of infected cells. Or, the T cell may activate a B cell to produce antibodies. Antibodies are proteins whose function is to detect any foreign elements that may enter the body. They normally detect specific parts of these elements, for example, proteins from the surface of bacteria or viruses. When antibodies bind to these foreign proteins, they act as a marker, making it easier for them to be recognised and eliminated by the cells of the immune system.Children living at high altitudes develop larger chest cavities by adulthood than children living at lower altitudes.

Amphibian species worldwide have been in decline. A significant proportion of the decline seems to be due to the spread of the chytrid fungus, Batrachochytrium dendrobatidis (Bd). Chytrid sporangia reside within the epidermal cells of infected animals, animals that consequently show areas of sloughed skin and are lethargic. The infection cycle takes four to five days, at the end of which zoospores are released from sporangia into the environment. In some amphibian species, mortality rates approach 100%. Apart from direct amphibian-to-amphibian contact, what is the most likely means by which the zoospores spread from one free-living amphibian to another?
Answer:
Water
Explanation:
The most likely means is water by which the zoospores spread from one living amphibian to another because amphibians lives in water and these zoospores can move in water and reach another amphibian causing infection to them. Amphibians are the organisms which lives both land and water. They requires water for reproduction so they lives at wet places. Zoospores have a unique structure which able them to swim in the water. So water is a great source of dispersal of zoospores from amphibian to amphibian.

Answer:
At the end of telophase II and cytokinesis, there are four haploid cells.cells.
Explanation:
During telophase II the sister chromosomes separate from each other and move to the opposite ends of the cell. Once that the chromosomes are in the opposite ends, the cytokinesis starts, this is the division of the cytoplasm that will give two daughter haploid cells.
We have to remember that there will be four haploid cells because there are two cells, which are the result of meiosis I, that will go into meiosis II to give these four daughters haploid cells. Also, the phases in meiosis I and II are very similar. Both of them have prophase, metaphase, anaphase, and telophase.
