Answer:
B
Explanation:
Muscles are predicted to shiver with greater force as the body becomes colder, as a response initiated by the brain's heat-gain center to generate heat and maintain body temperature.
Based on the data provided regarding shivering as a mechanism of thermoregulation, the best prediction is that muscles will shiver with greater force as the body becomes colder. This is because as the temperature drops, the brain's heat-gain center is activated, leading to an increase in random signals to skeletal muscles causing them to contract. Shivering involves these muscle contractions that generate heat to raise the body temperature and prevent the body from losing too much heat.

The cell membrane has two functions and one is a barrier keeping the constituents of the cell in and unwanted substances out and, second, to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.
The items in order from smallest to largest are: virus, bacteria, red blood cells, and nerve cell.
In order from smallest to largest, the items you listed can be arranged as follows: virus, bacteria, red blood cells, and nerve cell. A virus is the smallest out of these options, typically ranging around 20 - 400 nanometers. Bacteria are slightly larger, generally falling within the 1 - 10 micrometers range in size. Red blood cells are typically about 6-8 micrometers in diameter, which is larger than most bacteria. Finally, the nerve cell, also known as a neuron, is the largest of the group. The body of a neuron can range from 4 - 100 micrometers in diameter, and their axons, or long projections, can be up to one meter long.

b. Enter the sequence of bases as capital letters with no spaces and no punctuation. Begin with the first base added to the growing RNA strand, and end with the last base added.
Answer:
CCGAGU
Explanation:
DNA transcription:
DNA transcription is the process through which DNA double helical strand is converted into single stranded RNA molecule.
During transcription two strands of DNA are named differently i.e Template strand and coding strand.
Template strand:
Strand from which RNA is producing is known as template strand while
Coding strand:
The strand which is opposite to the template strand is known as the coding strand. Coding strand is the DNA strand whose nucleotide sequence resembles to the RNA transcript base sequence except thymine which is replaced by uracil.
Correct Answer:
Template strand from 5' to 3' reads GGCTCA. and
In this question CCGAGT is coding strand.
RNA sequence is same as coding sequence except T which is replaced by U so sequence of RNA becomes
CCGAGU
Best choice is True.
Hope this helped. ;)
