c. oxygen gas we breathe
Answer:
a. generated during bacterial infections
Explanation:

You have engineered a protein that contains a nuclear localization signal, a nuclear export signal, a C-terminal peroxisomal targeting signal, and an import signal for the endoplasmic reticulum. with all of these signal sequences, where would you expect to find the protein after its synthesis?
Answer:
The correct answer is - Endoplasmic reticulum
Explanation:
In this case, the N-terminal endoplasmic reticulum signal sequence of the engineered protein is recognized primarily. This signal is used to target the particular protein co-translationally, to the endoplasmic reticulum for post-translational modifications or changes.
Such post-modifications are glycosylation that taken place in the lumen of the endoplasmic reticulum. Other than Glycosylation Protein phosphorylation , Sumoylation and Ubiquitination, are other changes or modifications.

a.
53.6°F
b.
96.4°F
c.
122.0°F
d.
129.1°F
Answer:
96.4
Explanation:
The answer is at the top
When she asked at what temperature the pool was kept, she was told that it had a constant temperature of 35.8°C. The temperature is the pool in °F, to the nearest tenth is 96.4°F. Therefore, option (B) is correct.
The average kinetic energy of all of a substance's particles is used to measure temperature. The average kinetic energy of a substance rises with the speed at which its particles move, increasing its temperature and making it feel warmer.
One of the seven SI base units is the kelvin, which is the thermodynamic temperature unit. Curiously in the SI, we additionally characterize one more unit of constant temperature, called the degree Celsius (°C).

Which one of the following statements is wrong with respect to separation of DNA fragments on gel electrophoresis?
4 points
a. Gel electrophoresis is employed to check the progression of a restriction enzyme digestion.
b. The DNA fragments move towards cathode under electric field through the matrix.
c. The smaller DNA fragments moves farther.
d. The commonly used matrix is agarose gel.
Answer:
b. The DNA fragments move towards cathode under electric field through the matrix.
Explanation:
Gel electrophoresis is a molecular biology technique used to separate DNA fragments based on size using electric current. The electric current passes through a GEL (agarose gel is commonly used) matrix. Due to the fact that DNA is negatively charged, they tend to move towards a positively charged electrode called ANODE.
However, the smaller the size of the DNA fragment, the faster and farther it moves along the matrix. Gel electrophoresis is indeed a technique used to check how progressive a restriction enzyme has been able to digest DNA molecule into fragments.

Explanation:
Provide an explanation for why the indigo dye did not adhere to the different fibers in your test fabric. You will need to do a little bit of outside research on what chemicals make up some of the fibers. You may also need to do some research on intermolecular forces and why some interactions are stronger than others. Please make your explanation at least 500 words in two or more paragraphs. At least one in-text citation is required along with a list of your source(s) in your preferred citation style (MLA, APA, ACS, Chicago Style, etc.).
Answer:
Due to lack of bonds.
Explanation:
The indigo dye did not adhere to the different fibers because the indigo dye did not make bonds with the fiber, it only attached to it physically for temporary period of time. The reduced state is also necessary for indigo because indigo cannot dissolve in water, but when it is reduced it can soluble and able to get inside a fiber to make physical bond with the fiber. Some interactions are stronger than others because of the presence of strong bond between the two different materials so strong bonding makes the materials to attach with each other for a long period of time or permanently.

Juan and Carol were studying invertebrates in biology. They knew that segmented or earth worms preferred a dark, moist habitat. During this lab, they would be investigating the responses of organisms called planaria or Dugesia tigrina. These were simple flatworms that still had a one-way digestive system and a very simple nervous system. Juan and Carol placed the planaria in a petri dish containing cool, distilled water that was partially covered with black paper. They shined a light on the dish. Next, they removed the paper and placed a small amount of chicken liver at one end of the dish. They added a few large salt crystals to the water. Finally, they added drops of hot water to the cool water in the petri dish. Their results can be seen in the data table. According to their experiment, all BUT one conclusion is valid. A) Planaria are a fresh-water organism only. B) Planaria are consumers and may be carnivores. C) Planaria have specialized cells to detect light intensity. D) Planaria have specialized cells that detect temperature change. answer and you get all my points plzzz
Answer:
A) Planaria are a fresh-water organism only.
Explanation:
Planaria are a fresh-water organism only. Although the planaria moved away from the salt crystals, it may be because of the concentration of salt rather than its presence. There are both fresh water and salt water species of planaria. The other three conclusions are supported by the data.
Planaria are consumers and may be carnivores is the correct. Thus option B is correct
What is a planaria?
Planaria also called cross-eyed worms.
They are the tiny group of flatworms belongs to phylum Platyhelminthes.
They are free-living organisms in fresh water bodies.
The body are small, measuring around 3 to 15 mm , have a soft, leaf-shaped body covered cilia and spade-shaped head with two eyes
It is otherwise called as flatworms under the ancient class of Turbellaria which is in the branch of Platyhelminthes.
Planaria can sense and respond different stimuli like light where e eyespots can detect light and allow the organism to react to it.
It can sense Chemical by the help of their head regions allow them to smell.
The auricles of the head region can sense touch and allow them to respond.
Thus option B is correct
