Answer:
The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins.
Answer:
DNA digestion was not complete.
Explanation:
When a particular DNA needs to be used for the experiment, it is firstly processed by restriction digest. A restriction digest is a procedure for DNA preparation for further examination and manipulation. It is defined as a technique used for separating DNA fragments. This separation is being done using specific enzymes that will bond to specific sites and locations to the DNA so all DNA fragments will be a similar size. These enzymes are called restriction endonucleases or restriction enzymes and are extracted from bacteria for this particular cause. Once fractured or digested, DNA fragments may be amplified by PCR (polymerase chain reaction) and used for further experimentation.
When DNA is sequenced, all recognition sites (on enzymes) are visible and detectable. However, if an extra recognition site is found after sequencing, it means that initial mapping was not completed (assuming the DNA sequence has no errors). Initial restriction digestion was not completely done, so DNA is stuck in the middle of the process, in various degrees of supercoiling and digestion.
Answer:
The more alcohol you drink, the higher your heart rate gets,
Explanation:
The more you drink, the faster your heart beats. A recent study confirmed that binge drinking and long-term heavy alcohol use are associated with different types of cardiac arrhythmia, especially sinus tachycardia.
Answer:
a. movement can occur both upward and downward in the plant
Explanation:
The phloem loading causes the accumulation of sugars in the sieved elements generating a negative solute potential (quedas), with a drop in water potential (ψw), so water enters the sieved elements increasing the turgor pressure (ψp). With the discharge of phloem in the drain occurs lower concentration of sugars in the screened elements, increases the solute potential, becoming positive, thus the phloem water potential increases and thus the water leaves the conducting vessel. In the specific case of sugar movement in the phloem, it can be stated that this movement can occur both up and down in the plant.
Answer:
have similar cell structures
Explanation:
Archaea and bacteria are single-cell organisms that are classified as prokaryotes. They both possess similar cell structures as they tend to both have the same shape and size when viewed with a microscope. They both do not have a nucleus or other membrane-bound organelles like mitochondria and chloroplasts. One of the structures they share in common is the thread-like structure called flagella, which they use as in navigation around their environment.
Irrespective of the fact that they have similar cell structure, advanced studies have shown that archaea and bacteria have different genetic coding made of different proteins. Both cells also differ in the composition of their cell walls.
