Answer:

Translation uses DNA as a template to direct the synthesis of a RNA which in turn serves as a template for Translation which template is used to direct the synthesis of a polypeptide chain.

Without transcription, there will not be a mRNA strand to act as a template for translation by the ribosomes to occur at all.

Which statement correctly compares mass and weight?

hram777 [196]

Answer:

D. Weight varies with location, but mass does not vary

Explanation:

Weight can be defined as the force acting on a body or an object as a result of gravity.

Mathematically, the weight of an object is given by the formula;

$Weight = mg$

Where;

m is the mass of the object.
g is the acceleration due to gravity.

Mass can be defined as a measure of the amount of matter an object or a body comprises of. The standard unit of measurement of the mass of an object or a body is kilograms.

Irrespective of the location of an object or a body at a given moment in time, the mass (amount of matter that they're made up of) is constant. This ultimately implies that, whether you're in the moon, space, earth or any other place, your mass remains the same (constant).

<em>Hence, the statement that correctly compares mass and weight is that, weight varies with location, but mass does not vary. This is simply because acceleration due to gravity changes with location i.e its value varies with the planets.</em>

The first step leading to angiotensin II production is the secretion of what by the kidneys? Multiple Choice Calcitriol Angioten

Pachacha [2.7K]

Answer:

The correct answer is "Renin".

Explanation:

The secretion of the enzyme renin by the kidney is one mechanism used by the kidneys for blood pressure regulation. The secretion of renin is the first step leading to angiotensin II production, in what is known as the renin–angiotensin system (RAS). Renin catalyzes the conversion of angiotensinogen to angiotensin I, which is subsequently converted to angiotensin II by the angiotensin-converting enzyme (ACE).

Nutka1998 [239]

A species that is involved in a facultative mutualism with another: can utilize different resources outside of the mutualism.

Explanation:

Mutualism is a type of ecological relationship in which two organisms are related to each other in such a way that both of them could benefit from the relationship.
A type of mutualism in which the two organism cannot depend on any other resource outside their mutualistic relationship is called obligate mutualism.
A type of mutualism, in which the participating organisms can opt for other resources outside their mutualistic relatonship i.e. they are not completely dependent on each other, is called facultative mutualism.
