The correct answer is - D) covered by warm shallow seas.
The fact that the crinoids are have an abundance in the fossil records in Pennsylvania in the Mississippian Period, tells us that this area was covered with shallow and warm seas. The reason why we can get that conclusion is that the crinoids live only in that kind of environment, so it simply a logical conclusion.
The geological data is also confirming this, as it is easily noticeable in the layers that during this period of the geologic past, what is now Pennsylvania, was covered with shallow sea waters. Also, this waters were warm too, as the climate was warm and humid and that period, so it was a perfect environment for the crinoids to flourish.
The answer is false.
Energy used by the body to perform muscular contractions and many other energy-required functions is adenosine triphosphate or ATP.
The most important function of ATP is its ability to store and transport chemical energy within cells. That energy can be used for many chemical processes such as muscle contraction, nerve impulse propagation, chemical synthesis.. When consumed in metabolic processes as an energy source, it becomes converted either to adenosine diphosphate (ADP) or to adenosine monophosphate (AMP) because one or two phosphate groups are released (hydrolysis of high-energy bonds).
Since ATP is a nucleoside triphosphate it can be used for the synthesis of nucleic acids.
I would believe the correct responses would be option 1,2,4.
Answer: Burping (also known as "belching" or "eructation") is one way the human body expels excess gas in your digestive system. It occurs when your stomach fills with air, which can be caused by swallowing food and liquids. Drinking carbonated beverages, such as soda, is known to increase burping because its bubbles have tiny amounts of carbon dioxide in them.
As an avid soda drinker and statistics student, you notice you tend to burp more after drinking root beer than you do after drinking cola. You decide to determine whether there is a difference between the number of burps while drinking a root beer and while drinking a cola. To determine this, you select 20 students at random from high school, have each drink both types of beverages, and record the number of burps. You randomize which beverage each participant drinks first by flipping a coin. Both beverages contain 12 fluid ounces.
Explanation:
Answer: B
Explanation:
The question wants to know what the expression is directly dependent on.
The sequence of genetic expression goes like this:
DNA -> RNA -> protein
If we want to know the root cause of expression, we must look at the DNA, not the RNA or protein, because DNA determines the RNA and protein expression.
The Shape of subunits in DNA -> Sequence of bases coded for by the ribosome with RNA -> Arrangement of amino acids in the protein synthesized.
Why not C: Number of chromosomes present isn't a factor, because most humans, barring those with a genetic disorder, have 23.
