Describe the change that occur in the skin to get rid of excess heat.

Biology
1 answer:
AlladinOne [14]3 years ago
5 0

Answer:

brainly me

Explanation:

When we get too hot: Sweat glands in the skin release more sweat. The sweat evaporates , removing heat energy from the skin. Blood vessels leading to the skin capillaries become wider - they dilate - allowing more blood to flow through the skin, and more heat to be lost.

Sandra drew an isosceles triangle that has an angle that measures 46 degrees. Which could be the measures of the other two angle
kipiarov [429]

Answer:

46 and 88° or 67 and 67°

Explanation:

An isosceles triangle has two sides of equal length and one other of a different length;

A triangle with such features also has 2 equal angles and one other;

If we consider that 46° is the angle that is not one of the two equal ones, then we can calculate the other two;

All angles in a triangle sum to 180, so:

180 - 46 = 134

The two remaining angles constitute 134° collectively;

If they are equal, each angle can be found like so:

¹³⁴/₂ = 67

Each of the two equal angles will be 67°;

Alternatively, if 46° is one of the two equal angles, then these two angles will be:
46 × 2 = 92

Then, the remaining angle can be found like so:

180 - 92 = 88

So the angles within the triangle are either:

46, 46 and 88°

or

46, 67 and 67°

Drag the correct word from the left into the sentence on the right to complete each sentence. In anabolic reactions that involve
kkurt [141]

Answer:

The correct matches are:

  1. In anabolic reactions that involve the synthesis of a large molecule from smaller precursor molecules, NADH and ATP are consumed when they provide the needed electrons or energy.
  2. In catabolic reactions that involve the breakdown of a molecule into smaller subunits, such as glucose to pyruvate, NADH and ATP are produced.
  3. In the reaction Pyruvate +NADH-Lactate +NAD, pyruvate is being reduced.
  4. In the reaction Pyruvate NADH-Lactate +NAD, NADH is being oxidized.

Explanation:

  • Being involved in synthesis, anabolic reactions require energy in the form of energy storing molecules such as NADH and ATP. Anabolic processes utilize energy produced by the catabolism of complex compounds.
  • Catabolic processes produce energy or energy storing compounds by breaking down complex substances into simpler ones. All steps of cellular respiration are catabolic processes since they generate energy in the form of ATP or energy yielding molecules such as NADH and FADH2.
  • Anaerobic respiration takes place during intense physical activity due to which adequate oxygen does not reach the cells. Insufficient oxygen shuttles the pyruvate molecules produced by glycolysis into the lactic acid pathway that reduces pyruvate into lactic acid.
  • Since, NADH is donating its H+, it is being oxidized to NAD+.
