Answer:
Weight of the soil (500g)
Explanation:
According to this question, some students are conducting an experiment in order to find out which of the different soils used absorb heat the fastest. For the first test, they put 500 grams of SAND in a beaker and put a thermometer in the sand.
In an experiment, the variables that must be kept constant for all the groups is called the CONSTANT OR CONTROLLED VARIABLE. This is done in order not to influence the outcome of the experiment. In this case, the weight (500g) of the soil should be kept the same for all other tests.
This means that for the remaining soil being tested, 500g of each type of soil should be used.
Answer:
B
Explanation:
It would not be D because D is the location of a common ancestor, AKA an animal that does not haver jaws or bones. It would not be C because the question states that the fish has jaws, and C does not have jaws since the arrow does not point to that. It would not be A because the question states the fish has "NO TRUE BONES", meaning that there are no bones present. And in A, there is the bones arrow pointing to it, meaning that A has bones since that trait is on the same horizontal line as A. Only leaving us with option B left, since it came from an ancestor with jaws but not from an ancestor with bones. Sorry, I'm not the best with explaining but hopefully that makes sense why it is B, it's like a family tree, you just have to follow it carefully :) I hope that helps
I think the correct answer from the choices listed above is option D. Cross-pollination in corn plants is the mode of reproduction that is incapable of producing clones. With this reproduction, the result varies widely and the resulting plant is not the same variety of the parent plant.
Answer:
The correct answer is - option e. uses ATP as a substrate.
Explanation:
Poly-A Polymerase is an enzyme of the family of the DNA polymerase beta (polβ) family which catalyzes the reaction of the addition of AMP from ATP to the DNA polymerase beta (polβ) family.
ATP+RNA-3'OH--------->Pyrophosphate + RNApA-3'OH.
In this reaction, after the mRNA is cleaved, the Poly-A Polymerase template-independently adds about 200 A nucleotides (from ATP) one by one.
Answer:
Gene Therapy
Explanation:
<u>Gene therapy</u> is an attempt to correct a genetic disorder by replacing a mutated gene with a normal allele.
Gene therapy introduces a normal copy of the gene to restore the function of the protein if a mutated gene causes a necessary protein to be faulty or missing.
Gene therapy is a process in which a new, correct version of the cystic fibrosis transmembrane conductance regulator gene would be placed into the cells in a person's body.
