True or False: A neuron's response is all-or-nothing.
Answer:
TRUE
Explanation:The all-or-none law is a principle that states that the strength of a response of a nerve cell or muscle fiber is not dependent upon the strength of the stimulus. ... Essentially, there will either be a full response or there will be no response at all for an individual neuron or muscle fiber.
Answer: True
Explanation:
In 1956 Tijo and Levan first successfully counted human chromosomes. The reason it would have taken so manyyears to have done so would have included all but which of the following?
a. Watson and Crick's structure of DNA was not done until 1953.
b. Chromosomes were piled up on top of one another in the nucleus.
c. Chromosomes were not distinguishable during interphase.
d. A method had not yet been devised to halt mitosis at metaphase.
Answer:
A
Explanation:
The correct answer would be that Watson and Crick's structure of DNA was not done until 1953.
The fact that chromosomes are condensed together in the nucleus, are not distinguishable during interphase, and a method had not yet been devised to halt mitosis at metaphase could have plausibly delayed the successful counting of human chromosomes.
On the other hand, the discovery of the structure of the DNA could not have delayed the study of chromosomes because the DNA structure has no bearing on the karyotyping of chromosomes.
The chromosomes of organisms are best studied using a relevant microscope during metaphase when they would have fully decondensed and align at the equator of the cell or the metaphase plate. At the interphase phase of the cell cycle, chromosomes are full condensed under the view of the microscope.
The correct option is, therefore, A.

It was the big day; Lance had been training for months in anticipation of the annual “Dasher Twenty-Six-Two.” As he laced up his sneakers, he thought back to the endless grind of aerobic training he had accomplished. Hour after hour of lung-burning, quad frying jogging on pavement and dirty. He was ready mentally and physically, plus he had a secret weapon ready to go. Lance had been experimenting in the use of a thick, sugar saturated gel-nutrition to supplement his running. He anticipated finishing just before the three-hour mark and he planned to eat his special goo around hour two for a much-needed energy boost. The goo solution was a mixture of maltose, sucrose, and glucose, as well as some salt. Water would be available on the course every few miles and with his nutrition plan set he found his way to the line. *BOOM*
The start gun leaked smoke as wave after wave of runner set off. Miles started flowing by… five miles feeling good… Mile thirteen halfway there! Just as the two-hour mark was upon him, Lance pulled the gel from his pocket and slurped the gooey syrup down. Mile fifteen Phew, heavy legs… Mile eighteen Legs are burning but I got it… then came a hit of fatigue.
He had read about this before. The dreaded bonk. Bonking was said to be the final drips of glycogen being removed from the muscle’s cells, with an accompanying burn suggesting rapid production of lactate. It also meant he had spent the last two hours less aerobic than he thought. Making it to mile twenty-two, Lance noticed his heart rate ten-beats over his planned pace. His breath was getting harsher, his legs getting weaker. The mile twenty-four marker went by and he was down to nearly a walk, lips dry and stomach lurching. The last half mile was a blur as Lance crossed the line his raised arms quickly fell, and so did he, right into a chair near the finish line.
Discuss the necessity of Lance’s training to prepare for his ability to fuel a marathon with specific reference to the major organ systems involved and their purpose. Identify the needed reactants and excreted products Lance utilized during his ongoing respiring, with specific reference to where each is created or used. Finally, predict the influence of his experimental goo and suggest advantages and disadvantages to its use, as well as better use with reference to time and impact on the ability to enter and circulate to where it would be needed

tRNA molecules deliver amino acids to ribosomes where the amino acid next
A. forms an ionic bond with another amino acid
B. is deaminated and catabolized
С. becomes an anticodon
D. is covalently bonded to a growing polypeptide
E. forms hydrogen bonds with esters
Answer:
tRNA molecules deliver amino acids to ribosomes where the amino acid next becomes an anticodon (option C).
Explanation:
A tRNA molecule is able to deliver amino acids to the ribosomes for protein synthesis, forming an anticodon that complements the codon of the mRNA being translated. The mRNA molecules are responsible for conducting the genetic code —obtained from DNA transcription— to be translated by the ribosomes. This code is established by sequences of three nucleotides, called codons, which encode different amino acids.
What happens when mRNA molecules expose codons to ribosomes is that a tRNA molecule containing a complementary anticodon is formed, which is conducted to the ribosome to bind to the codon. This allows, according to the genetic code, the formation of a protein with a specific sequence of amino acids.
tRNA molecules deliver amino acids to ribosomes where the amino acid - С. becomes an anticodon.
During translation tRNA, molecules deliver amino acids to the ribosome and bind to this codon. It is a complementary anticodon to this codon.
Each tRNA molecule has two distinct endsone end binds to a specific amino acidthe other which binds to the corresponding mRNA codon. The first tRNA transfers its amino acid to the amino acid on the newly arrived tRNA, and a chemical bond is made between the two amino acids.Thus, tRNA molecules deliver amino acids to ribosomes where the amino acid - С. becomes an anticodon.

Why are the digestive systems of birds, ruminants and humans different?
Answer:
Humans and many other animals have monogastric digestive systems with a single-chambered stomach. Birds have evolved a digestive system that includes a gizzard where the food is crushed into smaller pieces.
Explanation:
Answer:
The digestion process in Ruminants is completely different from humans.
This is because the digestion process in Ruminants begins by chewing and swallowing its food. The main diet for these animals includes grass, leaves and other parts of plants.

What do you mean by adaptation?In biology, adaptation has three related meanings. It is the dynamic evolutionary process of natural selection that fits organisms to their environment, enhancing their evolutionary fitness. Secondly, it is a state reached by the population during that process.
The ability of living organisms to adjust themselves to their surroundings is called adaptation. Adaptations are the changes in structure or behaviour of an organism that will allow the organism to survive in that habitat.
Adaptations are unique characteristics that allow animals to survive in their environment. There are three types of adaptations: structural, physiological, and behavioral.

The batteries in a flashlight are Dead and the flashlight no longer works. What happened to the energy that was in the battery
Answer:
See the answer below
Explanation:
When the batteries in a flashlight become dead and the flashlight no longer works, it means that the chemical energy present in the battery has been converted to electrical energy to power the touch and eventually got lost to the environment as heat.
In a typical flashlight that works with batteries, the chemical energy in the batteries is converted to electrical energy, and this powers the bulbs in the flashlight. Gradually, the electrical energy is converted to heat energy and this is lost to the environment by radiation. When all the energy is lost to heat, the batteries are said to be dead and the flashlight stops functioning.
