<span>Proplatelets. Proplatelets are portions of megakaryocyte broken off to form a platelet by the force of blood flow. Megakaryocytes are large bone marrow cells responsible for producing blood platelets. Megakaryocytes form platelets either by breaking up explosively or by forming platelet ribbons. They produce blood platelets via intermediate cytoplasmic extensions known as proplatelets .</span>

Explain WHY photosynthesis and respiration are NOT able to create a cycle of energy?
jeka94

In a plant cell, photosynthesis and cellular respiration can both take place simultaneously. Plants carry out both photosynthesis and cellular respiration during the day. Cellular respiration continues because it provides the energy required for essential cell functions.

<h3></h3><h3>What role of  photosynthesis and respiration in plant?</h3>

Water and carbon dioxide are changed into oxygen and glucose during photosynthesis. The plant consumes glucose and produces oxygen as a byproduct.

Oxygen and glucose are transformed into water and carbon dioxide during cellular respiration. By-products of the process include carbon dioxide, water, and ATP, which is turned into energy.

To power cellular respiration, photosynthesis uses the energy it produces. During photosynthesis, solar energy is used, collected, and stored in the bonds of glucose molecules.

Therefore, photosynthesis and respiration not involve energy formation cycle.

5 factors that affect weather: geographic location/latitude altitude/height above sea level, ocean currents/large lakes, winds,t
Igoryamba

The statement is - True.

The five main factors that determine the weather at a certain place are the:

- geographic location/latitude

It determines the amount of sunlight, as well as the concentration of sun rays, which directly influences the temperature.

- altitude/height above sea level

The lower the place the warmer it is, the higher the place the colder it is, it is a simple rule that applies for all places on the planet, compared with places in their surroundings.

- ocean currents/large lakes

The ocean currents can bring cold and dry or warm and wet air masses, depending on what kind of an ocean current it is. The water also contributes to a more stable weather, with more moderate temperatures because of the thermal properties of the water to cool of and warm up slower than the land.

- winds

The air masses can bring cold and dry or warm and wet weather, so they influence the temperature and precipitation of a place.

- topography

Determines how much a place is exposed to the sunlight and the movement of the air masses.
