Answer:
CLAIM: IF THE FUSED B CANCER CELLS ARE GROWN IN A MEDIUM THAT DOES NOT CONTAIN NITROGEN SOURCE, THE CELLS WILL STOP SYNTHESIZING PROTEINS AND THEIR LIFE SPAN WILL BE GREATLY REDUCED
Explanation:
The growth medium that was used to reproduce the fused cancer B cells contains nitrogenous compounds that serves as source of nitrogen for the production of nitrogenous bases of DNA, If the nitrogen source is removed, the DNA in the nucleus of the white blood cell will lack adenine and guanine, which are necessary for the synthesis of DNA molecules.
2. Nitrogen is an integral part of DNA and protein. Nitrogen is needed to produce nitrogenous bases that are found in DNA. The DNA molecule is the one that initiate and direct the synthesis of protein in living cells.
In the fused B cancer cells, DNA must be produced, so that the dividing cancerous cells can continue their uncontrolled division, this will keep the cells alive. Nitrogen is also needed for the continuous synthesis of the special protein that the fused B cell is producing.
Thus, if nitrogen source is removed from the growth medium used for the cultivation of fused B cells, then the cells will stop synthesizing protein, their life span will be greatly reduced and they will eventually die out.

name three ways that you can explore specific genes to see if they would make good barcodes for species identification.
The barcode gene sequences should show less intraspecific gene variation than interspecific variation, contain conserved flanking regions and have a short length.
The three most important constraints to explore the suitability of a nucleotide sequence in order to be used as a DNA barcode for taxonomic identifications are:
Barcode gene sequences show less genetic variation within species (intraspecific variation) than between species (interspecific variation).Barcode sequences also show conserved flanking regions in order to be amplified in all species to be identified/categorized.Barcode sequences have short lengths due to technical constraints (amplification by PCR is ideal no more than 1000 base pairs).For example, in animals, an excellent barcode gene sequence used for taxonomic identification is the Cytochrome Oxidase I (COI) gene because this sequence can be used across the evolutionary spectrum.

Bacteria:
They are single-celled prokaryotic microscopic organisms.
They reproduce through binary fission.Binary fission is an asexual mode of reproduction.Some bacteria have the ability to grow even in the presence of antibiotics.In asexual reproduction DNA of the parent cell, replicates before division.Therefore, bacteria are single-celled prokaryotic microscopic organisms that replicate via binary fission.

Atoms are characterized by their protons and the number of
valence electrons. Which atom does this picture represent?
Answer:
carbon because its EC is 2:4 and the diagram shows 4electrons in its outer shell
How does this question represent the law of conservation of energy that energy cannot be created or destroyed? Consider the role of photosynthesis in your answer.
You need to put this into your own words, or else your school system will detect you copied from a source named Brainly.
Anyways, the law of conservation of energy is exactly what it says. Energy cannot be created nor destroyed. All they do is rearrange.
Now, for photosynthesis, it's an interesting thing. Photosynthesis takes the energy from the sun's light to produce sugars/carbohydrates. The sun's energy just got reused. It also uses water, which comes from the soil/ground. This simply, reuses the water. During photosynthesis, it also absorbs the carbon dioxide from the air. The carbon dioxide like everything else listed, got reused.
Meaning, energy does not leave. It endlessly works for different purposes. And as you should know, all of the water on the planet has been here since the dawn of time.
Hopefully this makes sense. Have a nice day!

the tensor fascia latae is involved in hip __________.
Answer:
Abductor Muscle.
Explanation:
The tensor fasciae latae works in synergy with the gluteus medius and gluteus minimus muscles to abduct and medially rotate the femur. The TFL is a hip abductor muscle. To stretch the tensor fasciae latae, the knee may be brought medially across the body (adducted).

A scientist hypothesizes that a new medication can reduce the chances of catching a cold. Which of these would most likely be the dependent variable in a study involving this medication?
A - The participants who do not receive the medication
B - The number of participants who catch a cold
C - The age of the participants
Answer:
B - The participants who do not receive the medication
Explanation:
I like to think of the dependent variable as the outcome variable. In this case it would be the number of people that catch a cold because it depends on if they take the medication or not.
