Many of the rate controllers mentioned for later walking also affect running. However, because running requires _______ generati
azamat

Answer:

greater, smaller.

Explanation:

Rate controllers are known to holds the emergence of the motor skill. These rate controllers are known to affect the running, walking and motor activites of the individual.

Running generally requires the greater generation of the force for the movement and to balance the ability. The smaller changes are required in these constraints that may cause the disappearance of the running skill.

Thus, the answer is greater, smaller.

Which statement BEST describes the relationship between mass and weight?
MArishka [77]

Answer:

The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.

Hope this helps:)

In a DNA double helix an adenine of one strand always pairs with a(n) _____ of the complementary strand, and a guanine of one st
notka56 [123]

Answer:

adenine pairs with Thymine  and guanine always pairs with cytosine respectively

Explanation:

In DNA nucleotide subunits, there are four nitrogenous bases:

  •    Adenine (A)
  •    Thymine (T)
  •    Cytosine (C)
  •    Guanine (G)

Each of these bases can be divided into two categories: purine bases and pyrimidine bases.

Adenine and guanine are examples of purine bases. This means their structure is a nitrogen-containing six atom ring joined with a nitrogen-containing five atom ring that share two atoms to combine the two rings.

Thymine and cytosine are examples of pyrimidine bases.

Note that  RNA replaces thymine with a different pyrimidine base called uracil (U).

The complementary base pairing rule, Chargaff's rule states that DNA base pairs are always adenine with thymine (A-T) and cytosine with guanine (C-G). A purine always pairs with a pyrimidine and vice versa. However, A doesn't pair with C, despite that being a purine and a pyrimidine.

Explica brevemente en que consiste la teoría de la deriva continental y menciona los contenientes que se crearon a partir de la
alisha [4.7K]

Esta teoría hace referencia al movimiento actual de las placas que sustentan los continentes y que se desplazan a lo largo de millones de años. En toda la historia geológica de la Tierra, los continentes no han estado siempre en la misma posición. Existe una serie de evidencias que veremos posteriormente que ayudaron a Wegener a refutar su teoría. El movimiento se debe a que continuamente está formándose nuevo material procedente del manto. Este material se crea en la corteza oceánica
