The difference between a pH of 5 and a pH of 8 is
Group of answer choices

A) 3x

B) 30x

C) 100x

D) 1,000x

Answers

Answer 1

Answer:

The correct answer is - D) 1000x.

Explanation:

pH is a logarithmic scale, 1 reading change leads to the results in ten-fold in the   H+ concentration in acidity/basicity. The more  H +  ions found in solution, the more acidic the substance is as acids donate  H +  ions.  

You can calculate the concentration of  H +  from the pH and the equation  

p H  = − log [ H + ]

arrange again

[ H + ]  =  10 − p H

So for a pH of 8, we get  [ H + ]  = 10 ^− 8

For a pH of 5, we get  [ H + ] = 10^ − 5

 10 ^−5  /10 ^− 8= 10 ^3

=  1000

What is a living cell? ​

Answers

Answer:

Though they are often debated, there are eight main characteristics that define a cell as living.

The first is genetic code. All living things contain DNA, which is like the instruction manual for life. DNA is contained in each cell, and passed from parent to offspring.

The second is growth and development. Whether by creating more cells or creating more organelles within the cell, all living things grow and develop.

The third characteristic is reproduction. Reproduction can be sexual or asexual, but in the case of single cells, it is asexual.

The fourth characteristic is response. All living things, including cells, react to external stimuli, such as temperature or salinity.

The fifth characteristic is homeostasis. Homeostasis is the condition by which living things maintain a stable internal environment in the midst of an ever-changing external environment.

The last three characteristics go hand in hand, and are sometimes combined, but in my mind they are distinctly separate.

Sixth is consumption, which is taking in food and other materials. A cell specifically takes in molecules such as water or glucose during consumption.

Seventh is metabolism, which is using materials consumed in order to create energy. Living cells use enzymes to break down materials to produce ATP (adenosine triphosphate), which is usable energy.

Finally, all living cells undergo excretion in some form. Some examples in cells include exocytosis and osmosis.

These 8 characteristics, though often controversial, determine a cell as living.

Once the neural plate edges have fused to become a neural tube, the tissues that were at the edges of the plate now form the __________ region the neural tube. Fill in the blank.

Answers

Answer: Dorsal.

Explanation:

The neural plate is a region of the dorsal ectoderm that develops into the neural ectoderm. It is a flat structure, with columnar appearing cells, and the formation of the neural ectoderm is the first step in the neurulation process. This region is generated from the thickened mid-dorsal surface opposite the primitive line of the ectoderm. From this epithelial zone the various types of neuronal and glia cells belonging to the nervous system are derived. For the neural plate to be built, it is necessary that the epiblast cells converge towards the midline of the embryonic disc forming a groove of the primitive line, delimiting a longitudinal axis of bilateral symmetry around which the embryonic structures and their organs will be aligned. From this moment on, the embryo will have a rostral (cephalic) and caudal (tail) region as well as a left and right side and a dorsal (back) and ventral (front) surface. From the folding of the neural plate or neurulation, the neural tube and the development of the entire nervous system will be formed.

The neural tube is tubular structure that undergoes modifications and will give rise to a central nervous system structure (encephalon and spinal cord).  The neurulation process begins by means of signals sent by the dorsal mesoderm and pharyngeal endoderm to the ectodermal cells located above these germ layers. These signals cause this area of the ectoderm to elongate into a columnar plate of cells. The elongation allows the differentiation of the cells of the future neural plate, with respect to the pre-epidermal cells surrounding the area.

So, the neural tube is formed by invagination from the dorsal region of the ectoderm (neural plate) induced by the notochord while it is forming. This occurs at the beginning of the third week of conception by a process called neurulation.

b) Most cells in their body contain multiple cancer-causing mutations
c) If they get malignant cancer, somatic mutations will not have been a factor
d) Their cancer will most likely arise in their germ cells, not their somatic cells
e) None of the answers effectively describes the situation
f) Every cell of their body contains a defective, loss-of-function allele of a tumor suppressor gene

Answers

Answer:

Every cell of their body contains defective , loss of function allele of a tumor suppressor gene

Explanation:

Tumor suppressor genes - They encode Proteins that inhibit cell proliferation . But due to Loss of functional alleles in Tumor suppressor genes it leads to the development of different cancers

Every cell of the body comprises of a defective and loss-of-function allele of a tumor suppressor gene.

The presence of defective and non-functioning tumor suppressor gene is responsible for the happening of cancer disease because the tumor suppressor gene slow down the process of cell division as well as repair mistakes occur in DNA molecule. When the tumor suppressor genes can't perform its function properly, it causes out of control growth of cell, which can lead to cancer disease so we can conclude that tumor suppressor gene is responsible for the cancer disease.

Identify the effects of the vagus nerve on the following components of the digestive system Salivary glands Pyloric sphincter (gastric emptying) Smooth muscle in the gallbladder Smooth muscle in the duodenal papilla (sphincter of Oddi)

Answers

Answer:

Vagus nerve is the 10th cranial nerve. It is long start from brain and distributed over head, thorax and abdomen.

Explanation:

1.   In the salivary gland the secretory and vasodilator effect on afferent nerve is mediated mainly by parasympathetic reflex which is given by vagus nerve.

2.   Pyloric sphincter is the part present between the stomach and small intestine which regulate the flow of food particles from stomach to the intestine. Vagus nerve control the activities of pyloric sphincter. Vagus nerve help the pyloric sphincter to relax.

3.  Efferent nerves of vagus nerve help the gall bladder to contract. Vagus nerve is stimulating the gastric tract to contract. So the vagus nerve stimulation promotpromotprthe production of CCK hormone and it will lead to the contraction and secretion of hormones from the gallbladder. Those contractions will help the gallbladder to empty the hormones from gallbladder.

4.  The efferent nerves of vagus nerves act on the smooth muscles of duodenal papila. As above says it lead to the contraction of smooth muscles and also promote the production of CCK.

What are the mechanism that use to resist the antimicrobial agents?

There has been several mechanisms, like resistance to antimicrobial agents, encapsulation or secretation of proteins that affects and might destroy the phagocyte along with some leukocytes in our body perform phagocytosis as a defense mechanism against the pathogenic bacterium.

These phagocytes contain lysosomes, intracellular granules that possess bactericidal substances. When the phagocyte ingests the pathogen, a phagosome is formed, which merges with the lysosome, forming the phagolysosome, which is where toxic substances and enzymes kill the ingested microorganism.

There are several mechanisms by which a microorganism can survive this process as resistance to antimicrobial agents. Some bacteria use phenolic glycolipids from their cell wall, to eliminate toxic oxygen compounds.

Explanation:

Mr. L was walking through the woods wearing shorts and sandals. He noticed a small tick on his ankle the same evening, and several weeks later he developed flu-like symptoms. A sample of his blood revealed the presence of long, wavelike cells that were twisting and waving. Based on the microscopic findings, which type of microorganism is responsible for Mr. L's symptoms

Answers

Answer:

Protozoa

Explanation:

The long, wavelike cells seen under the microscope would most likely be protozoa and the microorganism responsible for Mr. L's symptoms.

Tick as a vector is capable of causing diseases such as lyme disease, anaplasmosis, babesiosis, Powassan virus disease, tularemia, and a host of other diseases. Among all the diseases, babesiosis is particularly caused by a protozoan known as Babesia microti and it elicits malaria-like symptoms in individuals. Most of the other diseases are caused by bacteria pathogens while a few are caused by virus.

Apart from the above, the morphological characterization of the microorganism responsible for Mr. L's disease is typical for protozoans. Many of them are long and flagellated with a wave-like motion as a movement.

Hence, the case of Mr. L would be that of protozoa.

Answers

Answer:

There are no tables but it should be a bell curve. as a population of whales rise the population of seals will decrease, eventually creating a plateau in the whale population. shortly after the plateau in the whale population the whale population will begin to decline ( as food becomes less available) causing the seal population will begin to rise and restabilize. this pattern should continue cyclically creating a wave function on a graph!
