✎﹏☾✦☁️❣️ Briefly explain the process of photosynthesis .❣️☁️
Answer:
hope this will help u
Explanation:
photosynthesis is the process in which plant make their own food with the help of sunlight,water and carbon dioxide. water and carbon dioxide are raw materials in photosynthesis because they help to prepare their food.During photosynthesis, plants take in carbon dioxide and water from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
Explanation:
PHOTOSYNTHESIS
This is a process in which green plants and other organisms make their own food from simple inorganic substances which are sunlight ,CO2 and chlorophyll.

Answer:
Ambos son similares en sus acciones.
Explicación:
La principal diferencia que existe entre los métodos citotóxicos y citotóxicos es que los citotóxicos son las sustancias que envenenan la célula, mientras que los métodos citotóxicos son las formas de toxicidad celular. Tanto los métodos citotóxicos como los citotóxicos son similares en su acción porque tanto los métodos citotóxicos como los citotóxicos dañan la célula. Tanto en los métodos citotóxicos como en los citotóxicos, ambos causan toxicidad en la célula que inhibe el crecimiento y la estructura normales de la célula.

Would it be justified to call Kreb's Cycle the central wheel of metabolism? Why? Provide two specific pieces of evidence to support your answer.
Answer:
Yes.
Explanation:
Kreb's Cycle is considered as the central wheel of metabolism because the fuel molecules are oxidized ultimately within the Krebs Cycle and its intermediates are used for various biosynthetic pathways. The main function of the Kreb's cycle is to produce electron carriers that can be used in the cellular respiration for producing energy molecules in the form of ATP. without Krebs's cycle, the cell produces only two ATP molecules which very low.

What is Stars?A star is the most well-known celestial object and the main building block of galaxies. The age, distribution, and composition of a galaxy's stars can be used to determine the galaxy's history, dynamics, and evolution.
In addition, stars generate and disperse heavy elements like carbon, nitrogen, and oxygen, and their characteristics are strongly tied to those of any planetary systems that may develop around them.
The study of the origin, development, and death of stars is thus at the heart of astronomy.
Therefore, Stars are hot objects and give off heat and light. Composition and exact mass are the things about stars.

To begin with, in 1963 the psychologist Raymond Cattell introduced the concepts of both Fluid intelligence and Crystallized intelligence in where he explains that both are derived of the General intelligence. The first one refers to the ability of solve novel reasoning problems and is related to the capacity of important skills such as comprehension, learning and more. And the second one, the Crystallized intelligence refers to the ability of learn procedures and more technical knowledge about certain topics reflecting the effects of experience about that.
