Answer:
b. The red and green inks will be uniformly distributed throughout the pan.
Explanation:
The inks distribute throughout the particles of water. It does not matter that one drop of ink was placed in one end, and the other on the other end. The constant movement and collision of particles make the ink's drop distribute uniformly in the pan. Besides, there will we a tendency to have the same amount of ink concentration in all the pan; to this, they have to distribute evenly.

You are doing an experiment in which you are using an in vitro translation system derived from rabbit reticulocytes, called a rabbit reticulocyte lysate, to translate mRNA in a test tube. The rabbit reticulocyte lysate contains ribosomes, translation initiation and elongation factors, tRNAs, aminoacyl tRNA synthetases, release factors, amino acids, and ATP. The lysate does not contain any mRNA, so you must add the mRNA you would like to translate to the system. A. When you analyze the proteins made from your lysate, you find that they are all only two amino acids long. At first, you think that there must be a mutation to a stop codon in the position of the third codon, so you do another experiment with a different mRNA. Again, all the newly synthesized proteins are only two amino acids long, so you conclude that there is a problem with some component in your lysate.
Describe ONE possible problem in the translation system (lysate) that would result in the limitation of newly synthesized peptides to two amino acids in length.
Answer:
Problems with transfection efficiency or absence of essential mRNA modifications (capping and poly-A tail)
Explanation:
Translation is the process of protein synthesis from RNA in which the genetic information encoded in a messenger RNA (mRNA) molecule is translated into a protein sequence composed of amino acids. Translation has three steps: initiation, elongation, and termination. During translation, different elements are required to initiate, continue and complete the process, which include essential molecules such as amino acids, mRNA, tRNAs, ribosomes, energy-carrying molecules (i.e., ATP, GTP), initiation factors (i.e., eIF1A, eIF3, etc) and elongation factors (eEF-2, EIF5A). For example, humans can't synthesize nine essential amino acids (i.e., threonine, tryptophan, phenylalanine, valine, methionine, leucine, histidine, isoleucine, lysine), thereby it is imperative to include these amino acids to synthesize proteins composed of them. On the other hand, it is also fundamental to take into account that the efficiency of transfection of the molecules required during translation, as well as the absence of modifications in the mature mRNA sequence, may alter the process in vitro.
In a cell with defective chaperones, Question 14 options: proteins would not be able to exit the ribosome. the concentration of misfolded proteins would be higher than normal. proteins would not be delivered to their appropriate cellular locations. ribosomes would not associate with the endoplasmic reticulum.
Answer:
the concentration of misfolded proteins would be higher than normal.
Explanation:
Chaperones proteins are required for the correct protein folding of proteins. These proteins were first discovered in bacteria. The level of chaperones is increased under thermic stress conditions, it is for that reason that they are also known as heat shock proteins (Hsp). For example, Hsp70 is a chaperon protein constitutively expressed under stress conditions that is involved in the folding of protein precursors and the refolding of misfolded proteins. In humans, Hsp70 is encoded by the HSPA1A gene, and its increased expression level is related to different health problems including neurodegenerative diseases, cerebral ischemia and epilepsy.
You have a nutrient broth, an agar slant, and an agar plate with bacterial growth in or on each. If you wanted to evaluate the macroscopic appearance of the bacteria growing in or on the medium, which of the cultures would be the best choice?
A. Agar slant
B. Broth
C. Agar plate
Answer:
The best option would be breeding ground.
Explanation:
The broths of culture show us better the macroscopy of the colonies of the bacteria, that is to say the forms of the bacterial groups, some bacteria are usually circular, others lunar, etc.
On the other hand, the environment in which you want to develop a bacterium depends fundamentally on its metabolism, since some should be analyzed on blood agar, or other means, which is why this response is considered very subjective.

Drag each tile to the correct box. Arrange the stages of the frog’s life cycle from first to last. ↓ ↓ ↓ ↓
You didn't put the answer options, but the frog life cycle phases are:
Mating: In this phase two adult frogs, a male and a female, mate in the water or on plates. At this point, the male frog wraps his arms around the female and overlaps over her back. Spawning: At this point, the female releases the eggs into the water, ready to be fertilized by the males. Fertilization occurs outside the female's body. Eggs: Some fertilized eggs will be devoured by small animals, but those that survive will hatch 7-9 days after fertilization, releasing a frog shape, called a tadpole.Tadpole: It is similar to a fish and is formed by tail, mouth and gills. After 7 days of life, you will be able to swim and feed on algae. Four weeks later he will develop teeth and skin. When he reaches 9 weeks he will begin to change his shape, growing in size and developing head and legs. At that moment it will look more like a frog, but it still has a long tail. Metamorphosis of the fish: Up to twelve weeks of age it will reach the shape of a frog and start to feed on insects. Gradually it will lose its tail and its tongue will grow. The 16 weeks will become an adult frog, being able to mate and restart the cycle.Answer:

Which of the following statements is true if a cell has a moderate number of mitochondria, well-developed rough endoplasmic reticulum, many ribosomes, a well-developed Golgi complex, and no secretory vesicles?
a. This cell function is to produce steroids
b. There would need to be fatty acids and glycerol in the cytoplasm
c. The product made in this cell would be exported from the cell
d. There are moderate energy demands in this cell
e. There would need to be amino acid in the cytoplasm of cell
Answer: Option D.
There are moderate energy demands in this cell
Explanation:
The rough endoplasmic recticulum is an organelles in the cell that has many RIBOSOMES. These RIBOSOMES are important for the synthesis of proteins. And the Golgi apparathus is responsible for protein modifications into different functions after receiving it from rough endoplasmic recticulum
But without secretory vessicles, Amino acids will not be transported in the cell. Without it been transported, there is moderate demands in the cell because energy is required to transport and modify proteins by the secretory vessicles. Mitochondria is the power House of the cell or it produce energy, moderate number of mitochondria means that moderate or few energy will be supply to the cell organelles for proper functioning and processes because energy is required for cellular activities.
The diagram shows animal and plant cells placed in 3 different types of solutions.
a) Name the 3 types of solutions taking inference from the picture above and explain the process taking place in A
b) When plant cell is placed in solution C, which part prevents it from bursting and how?
c) Name the process by which Amoeba obtains its food
This diagram shows vegetal and animal cells placed in solutions of different concentrations.
a)Solution A is called hypertonic because it has a higher concentration than the cell's cytoplasm. In the animal cell, it causes the water to diffuse out through osmosis. In the plant cell water is lost through the same process but the cell wall remains intact while the membrane reduces in volume.
Solution B is called isotonic because it has around the same concentration as the cytoplasm of the cell. It does not influence the volume of the cell.
Solution C is called hypotonic because it has a lower concentration than the cytoplasm. In the animal cell, it causes the cell to fill with water until it bursts(this process is called cytolysis). In the plant cell water diffuses through the membrane, but the cell doesn't burst.
b)Plant cells have a strong cell wall made of cellulose, hemicellulose and, lignin that prevents cytolysis.
c)Amoeba obtains its food through a process called phagocytosis in which the solid material is engulfed in a vesicle that enters the cell.
Plant cells have a strong cell wall made of cellulose, hemicellulose and, lignin that prevents cytolysis.
What do you mean by cytolysis?Cytolysis, or osmotic lysis, occurs when a cell bursts due to an osmotic imbalance that has caused excess water to diffuse into the cell. Water can enter the cell by diffusion through the cell membrane or through selective membrane.
Cytolysis or osmotic lysis occurs in animal cells and certain bacteria, especially when the cells are exposed to a hypotonic environment, causing the water to move into the cell, thereby increasing or expanding the cell.
When cells burst and die, their contents are released, causing inflammation. Every day, more than 50 billion cells die in our bodies. These are not random events, but part of a finely tuned biological mechanism called programmed cell death.

Explain the differences between osteoporosis osteoclasts and osteocytes. How do these cells work together to remodel bone? What happens if the activities of osteoblasts and osteoclasts are imbalanced
Answer:
Osteoporosis is a condition when bones get porous and break easily, while
Osteocytes are what people call virgin bone cells (or osteoblasts) once they become hardened into place.
Osteoclasts break down bone when it grows beyond where it needs to be.
Explanation:
Throughout our lives, bone is deposited, broken down, and replaced. When an arm or leg is broken, the blood vessels at the area have the ability to increase calcium phosphate deposition to help heal the break. Newly trapped osteoblasts, called osteocytes, form the new bone framework. These cells can no longer produce new bone and become the basic framework for the new bone.
Osteoclasts, the second type of bone cell, are specialized to dissolve bone. As bones grow, they need to be reshaped. Simply add- ing layer upon layer of calcium phosphate would not maintain the proper shape of the bone. Therefore, as bones grow, the osteoclasts secrete enzymes that help dissolve certain areas of the bone.

Explain the process of breathing begin with inhalation and describe the route that the air takes to the lungs and what happens when the air reaches the lungs include in your description the terms mouth nose pharynx larynx trachea bronchi lungs alveoli carbon dioxide oxygen and capillaries..... PLEASE HELP PLEASE
Answer:
Please find the detailed explanation below
Explanation:
The breathing process is the process of breathing in, also called inhalation and breathing out, also called exhalation. Inhalation and exhalation are important processes for a smooth respiratory experience.
Air (containing oxygen) from our external environment enter our body system via our MOUTH or NOSE. The air then passes from the PHARYNX into the LARYNX or voice box, which connects into the TRACHEA or wind pipe, which conveys the air into the lungs via its branched tubes called BRONCHI. These pipes that air passes through in order to reach the lungs are generally called AIR WAYS.
Inhalation (breathing in) involves the taking in of air into the LUNGS (main organ of respiration). It occurs when the diaphragm (muscle separating the thorax from abdomen) contracts and moves downward towards the abdomen. This allows the lungs to expand, allowing air to enter into the lungs via the NOSE or MOUTH down the TRACHEA or windpipe.
As soon as air reaches the lungs, the air passes through the bronchi (tubular branches of the trachea) into the ALVEOLI or air sacs. The delivery of oxygen in the inhaled air is carried out in the CAPILLARIES (a blood vessel that carries blood) that surrounds the alveoli. This alveoli conveys oxygen from the lungs into the bloodstream and carbon dioxide out of the bloodstream into the lungs (a process called GAS EXCHANGE).
Breathing out or exhalation of the carbon dioxide in the lungs (waste product of respiration) occurs when the diaphragm relaxes and moves upward, causing the lungs to deflate as the carbon dioxide is released through the trachea into the mouth or nose where it leaves the body system.
