Answer:
A) Steroid hormones travel in the plasma on large transport proteins that cannot pass through the filtration membrane
The given question is incomplete as it lacks the map which is important, however the correct answer is attached:
Answer:
The correct answer is -
Top box (green area) - moderate rain,
Middle box (sky blue area) - light rain, and
Bottom box (red area) - heavy rain.
Explanation:
As per the map and the scale presented on the map that indicates the rainfall in inches. The green area indicates that the rain fall in this area is one inch which is moderate as the the sky blue rainfall measurement is .5 inches which is half. However, the red area is the highest rainfall area in comparison to both of these which is about four inches.
On the basis of these it we can label all three boxes as per their rainfall amount that is,
Top box (green area) - moderate rain,
Middle box (sky blue area) - light rain, and
Bottom box (red area) - heavy rain.
Answer:
Genomic Instability
Explanation:
Normal cells have normal DNA and a normal number of chromosomes. Cancer cells often have an abnormal number of chromosomes and the DNA becomes increasingly abnormal as it develops a multitude of mutations.In contrast to normal cells, cancer cells don't stop growing and dividing, this uncontrolled cell growth results in the formation of a tumor. Cancer cells have more genetic changes compared to normal cells, however not all changes cause cancer, they may be a result of it.
Answer:
A mutation in <u>DNA </u>results in a change in <u>RNA </u>that sometimes produces a <u>protein </u>with altered structure and function.
Explanation:
DNA is the hereditary material which causes gene expression in our body by producing protein. The type of protein which is produced by DNA totally depends upon the sequence of nucleotides in the DNA. But, DNA molecule does not produce protein directly. Initially it produces RNA (mRNA, tRNA, rRNA) by the process of transcription, the nucleotides in the RNA are complimentary to those in DNA. In short, the message regarding the structure and composition of the type protein to be produced by DNA is first decoded from DNA in the form of RNA. These RNA molecules then synthesize the protein as per the instructions from DNA by the process of translation.
But, in case a mutation occurs in the DNA which causes a change in it's nucleotide/nucleotides, the protein which will be produced will be different in the structure and function than the protein which was supposed to be synthesized. It happens because, a triplet of nucletiodes in the DNA and hence RNA specifies a particular type of amino acid and several amino acids are joined in a long chain to form polypeptide which ultimately forms protein. But, if any nucleotide in the triplet is changed due to mutation it may change the amino acid and if amino acid will change the protein will also get altered.
Bacterial responses to antibiotics are concentration-dependent. At high concentrations, antibiotics exhibit antimicrobial activities on susceptible cells, while subinhibitory concentrations induce diverse biological responses in bacteria.
