Answer:

c. Carbon Dioxide

Explanation:

The rate of respiration is determined by the presence of concentration of carbondioxide gas in the blood because in the process of respiration, energy in the form of adenine tri phosphate (ATP) and carbondioxide gas are produced. This ATP is required for performing different activities while carbondioxide gas is a waste product which must be removed from the blood through breathing. If carbondioxide gas is produced quickly so the rate of respiration is also increased in order to remove the gas from the blood.

IF A CUBE IS 1CM ON A SIDE, CALCULATE ITS SURFACE AREA. HINT WRITE 2 points
frosja888 [35]

Answer:

Surface area of the cube = 6cm²

Volume of the cube = 1cm³

Explanation:

The surface area of a cube, which refers to the sum of all the areas of the faces of the cube can be calculated using the formula:

S.A = 6 × a²

That is; a² + a² + a² + a² + a² + a²

Where;

a = length of a side of a cube

a² = area of one side of a cube

Note that, a cube has 6 faces

According to this question, a cube has a length of 1cm on each side.

Hence, S.A = 6 × 1²

S.A = 6 × 1

S.A = 6cm²

Volume of the cube can be calculated using the formula: a³

Where a = 1

Volume = 1 × 1 × 1

Volume = 1cm³

Which three of the following statements accurately describe the blood buffering system in humans? the blood buffering system . .
Bogdan [553]
The truth about blood buffering is that 1). mantains the ph of blood near to 7.4. 2) utilizes the H2CO3/HCO3– conjugate acid/base pair and 3) is facilitated by the enzyme carbonic anhydrase, which interconverts carbon dioxide and water to carbonic acid. Have in mind that the buffer is written as the following: <span>CO2(aq) + H2O(l) <==> H+(aq) + HCO3^-(aq) </span>

State one effect the reintroduction of the wolf may have on the coyote population within the Adirondacks
Masteriza [31]

Answer:

Decrease in the population of coyote occurs after the reintroduction of the wolf within the Adirondacks  effect.

Explanation:

Wolves are the top predator in the ecosystem. They hate coyote and kill them and sometime eat them too. So the reintroduction of the wolf decreases the population of coyote by killing them directly and by consuming the prey and the coyote die due to hunger. Coyote feed on rabbit, snakes, deer, fruits and grasses so decrease in coyote population increases the availability of grasses and other animals for different animals.
