As a whole, plants tend to release more oxygen than carbon dioxide into the environment, but the ratios of gases differ at vario
marshall27 [118]

During the day, due to the existence of sunlight, the procedure of photosynthesis elevations over that of respiration. Photosynthesis uses carbon dioxide to produce carbohydrates removing oxygen as a byproduct. During the night, because there is no sunlight, the rate of photosynthesis decreases. This, therefore, drives the rate of respiration to surpass the speed of photosynthesis. In respiration, oxygen is consumed and carbon dioxide is dismissed.

<h3>What is photosynthesis?</h3>
  • Photosynthesis is the process by which manufacturers use sunlight, water, and carbon dioxide to produce oxygen and energy in the form of sugar.
  • The primary position of photosynthesis is to transform solar energy into chemical energy and then reserve that chemical energy for prospective use. For the most part, the planet's living designs are powered by this process.
  • An illustration of photosynthesis is how plants convert sugar and significance from water, air, and sunlight into energy to grow. Description of photosynthesis is the procedure through which plants use water and carbon dioxide to assemble their food, grow and remove excess oxygen into the air.

What is the physical property to all of these (pls answer I’ll give brainliest)
Sav [38]

Answer:

Explanation:

Brittleness : The ability of an object to break apart or shatter easily

Ductility: The ability of a substance to be stretched out into a long wire-like shape.

Lustre: the ability of an object to reflect light.

Malleability is a substance's ability to deform under pressure

The melting point of ice is 0°C. The melting point of a solid is the same as the freezing point of the liquid

Solubility is the relative ability of a solute to dissolve into a solvent.

solid: Has a definite shape and volume.

liquid: Has a definite volume, but take the shape of the container.

gas: Has no definite shape or volume. change of state

The resistance of a liquid to flowing is its viscosity.

a boy capable of swimming 2.1m/a in still water is swimming in a river with a 1.8 m/a current. At what angle must he swim in ord
mr_godi [17]

Answer:

The boy must swim at an angle of 59°northwest to get to a position directly opposite his starting point.

Explanation:

To get to a point directly opposite his starting point, the boy must travel at an angle x, in a direction northwest of his starting point. The speed of the boy and the speed of the river current forms a right-angled triangle with an an opposite side of 1.8 m/a and a hypotenuse of 2.1 m/a having an angle x.

Sin x = opp/ hyp

Sin x = 1.8/2.1

x = sin⁻¹ (1.8/2.10

x = 58.99

x = 59°

Therefore, the boy must swim at an angle of 59° in the northwesterly direction to get to a position directly opposite his starting point.
