Which of the following is a skin sensory receptor for touch?
A) Pacinian corpuscle
B) Meissner's corpuscle
C) Ruffini body
D) free nerve ending
Meissner's corpuscle is a skin sensory receptor for touch.
Meissner corpuscles are responsible for the sense of touch or light pressure, that is, they are very sensitive to the movement of objects on the skin and to very low vibrations.
About Meissner corpuscles:
• They are located on the lips and fingertips and are very sensitive.
• Meissner corpuscles act when there is a soft and light touch, and when vibrations are less than 50 hertz.
• These receptors can be altered when there is the presence of diseases where both thermal and tactile sensitivity are altered.
Therefore, we can conclude that Meissner corpuscles detect fine touch, that is, they are receptors on the skin that are sensitive to low-frequency vibration.

Answer:
The curve that most closely describes the mean tempretire of the fluid as a function of position along the tube.
Explanation:
Hello. Your question is presenting very confusing words, however, through the context of the question as a whole, it is possible to see that you are saying that the water that enters a circular tube has a lower temperature than the temperature presented by the surface of the tube . In this case, if you are going to present a graph about this, it is important that this graph presents a curve that shows the relationship between the average water temperature as a function of the position of the water along the tube. This graph will be similar to the graph shown in the attached figure below.

The arctic fox has a diploid number of 50 an arctic fox was forming gametes by meiosis, how many chromosomes would be visible in prophase 17 Are the chromosomes replicated or non-replicated?
a. 2. 50; unreplicated
b. 28; replicated
c. 100, replicated
d. 25: unreplicated
e. 6.50; Replicated
Answer:
50 visible chromosomes and replicated.
Explanation:
Diploid number 50Haploid number 25When we talk about the cell cycle, we refer to the interphase and the cell division (mitosis or meiosis).
Interphase is composed of stages G1, S, and G2. During the S stage, the DNI replication process occurs. This is the only stage in which the DNI molecule replicates. The synthesis of histones and other associated proteins also occurs.
Meiosis occurs after the interphase is over.
Meiosis produces four daughter haploid cells (n) from a diploid germ cell (2n). Each daughter cell is haploid because they have half the number of chromosomes of the original one.
At the beginning of prophase 1, DNI is condensed in a well-defined chromosome formed by two sister chromatids joined by a centromere. Each chromosome carefully pairs with its homologous chromosome. Homologous chromosomes aline together to make the crossing-over possible, the stage where they interchange their parts.
The whole set of chromosomes is present in prophase 1. The reduction occurs later.
So if the germ cell has 50 chromosomes, the same 50 will be visible during prophase 1. DNA has already been replicated during the S stage of interphase.
A researcher wanted to create a loss of function mutation for studying Type I Diabetes in a model animal. What mutation would mimic Type I diabetes?
a) Inhibition of sugar absorption in the small intestine
b) Inhibition of pancreatic beta-cells
c) Up regulation of insulin receptors on the pancreas
d) Down regulation of GLUT4 transporters in muscles
Answer:
The correct answer is: b) Inhibition of pancreatic beta-cells.
Explanation:
Type 1 Diabetes is a form of Diabetes Mellitus, a condition characterized by chronic hyperglycemia (high blood sugar levels) that can compromise many organs and even cause death if not treated properly.
The most common form of Diabetes Mellitus is Type 2 Diabetes, in which the pancreas produces insulin but cannot reach the target organs because of a pathologic state called Insulin Resistance.
Type 1 Diabetes, instead, is present in patients that cannot produce insulin on their own. Insulin is the most important hormone in the regulation of blood sugar - it is secreted by the pancreatic beta-cells when glycemia rises (which is normal after eating) and it is key in allowing glucose to reach the tissues where it's needed for energy requirements. Type 1 Diabetes is usually diagnosed in young, even pediatric, patients - the pancreatic beta-cells in these individuals are destroyed and unable to function (the reason for this is not clear in all cases), so they have to be administered with exogenous insulin to survive.
For the model animal to better represent Type 1 Diabetes, the mutation would have to inhibit pancreatic beta-cells.

Answer:
birds have feathers, reptiles have scales
birds are endothermic, while reptiles are generally ectothermic
Explanation:
The main difference between birds and reptiles is that birds have feathers on their body while on the other hand, reptiles ahve dry skin and have scales. Reptiles are ectotherms, while birds are endotherms. An ectotherm relies on its external environment to regulate the temperature of its body whereas Endotherms are able to regulate their body temperatures by producing heat within the body.

While alive, an organism absorbs (radioactive) carbon 14 at such a rate that the proportion of carbon 14 in the organism remains at a known constant level. When it dies, it no longer absorbs carbon 14, so its proportion of carbon 14 begins to decrease. The half-life of carbon 14 is 5,600 years. A human skeleton is discovered whose level of carbon 14 is 15% that of a living human. To the nearest 100 years, how long ago did the person die
Answer:
The person has been dead for approximately 15,300 years
Explanation:
Available data:
The half-life of carbon 14 is 5,600 yearsThe human skeleton level of carbon 14 is 15% that of a living humanTo answer this question we can make use of the following equation
Ln (C14T₁/C14 T₀) = - λ T₁
Where,
C14 T₀ ⇒ Amount of carbon in a living body at time 0 = 100%C14T₁ ⇒ Amount of carbon in the dead body at time 1 = 15% λ ⇒ radioactive decay constant = (Ln2)/T₀,₅T₀,₅ ⇒ The half-life of carbon 14 = 5600 yearsT₀ = 0T₁ = ???Let us first calculate the radioactive decay constant.
λ = (Ln2)/T₀,₅
λ = 0.693/5600
λ = 0.000123
Now, let us calculate the first term in the equation
Ln (C14T₁/C14 T₀) = Ln (15%/100%) = Ln 0.15 = - 1.89
Finally, let us replace the terms, clear the equation, and calculate the value of T₁.
Ln (C14T₁/C14 T₀) = - λ T₁
- 1.89 = - 0.000123 x T₁
T₁ = - 1.89 / - 0.000123
T₁ = 15,365 years
The person has been dead for approximately 15,300 years

Why do some people argue that scientists should not use embryonic stem cells in medical research?
A. They think research conducted on these stem cells is not applicable to adults.
B. They think the use of these stem cells is too expensive.
C. They think the use of these stem cells is the same as ending a life.
D. They think research conducted on these stem cells is too difficult.
[tex] \huge \rm \pink{answer}[/tex]
D. They think research conducted on these stem cells is too difficult.
They argue because they think the use of these stem cells is the same as ending a life. Therefore, option C is correct.
This viewpoint is rooted in ethical and moral concerns. Embryonic stem cells are obtained from human embryos, usually from unused embryos created during in vitro fertilization (IVF) procedures. Opponents argue that using these stem cells for research purposes involves the destruction of potential human life since the embryos are destroyed in the process of harvesting the cells.
The ethical debate surrounding embryonic stem cell research centers on the question of when life begins and whether it is ethically justifiable to use human embryos for scientific purposes.

Chloroplasts are the organelles where photosynthesis occurs, and they provide the necessary structures and molecules for capturing light energy, generating ATP and NADPH, and converting carbon dioxide into organic compounds.
They are essential for the survival and growth of autotrophic organisms and form the basis of the food chain on Earth.
