What is mitosis the divison of?

Genetic disorders or diseases that are caused by errors that occur during meiosis is called down syndrome. It is also known as trisomy 21. In this disease the person inherits one extra pair of chromosomes from one of the parent i. e. Father or mother.

in experiment 1, which of the following factors was systematically changed so that its effects could be observed? A.light intens

Stels [109]

Explanation:

<u>A.light intensity</u>

<u />

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Carbon dioxide + water + energy= glucose + oxygen

At the compensation point, the rate of CO2 production by respiration matches the rate of CO2 utilization in photosynthesis- there is no net CO2 production . Since photosynthesis is rate limited, the rate of energy intake can be reduced in order to reach the compensation point; lowering the light intensity would slow the rate of photolysis and thus photosynthesis. Similarly, an increase in light intensity

increases the rate of photosynthesis- the CO2 level would be reduced as more inorganic CO2 is fixed, together with producing O2 as waste.
would increase the temperature of the environment- light energy is converted to heat energy which increases temperature.
lead to higher levels of humidity- the heightened temperature increases the rate of evaporation of water from tissues, and thus increases the humidity (water vapor content of the surrounding air)

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

Occuring in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions and produces molecules of the energy storage molecule ATP through an electron transport chain. This occurs in the thykaloids, where pigment molecules like chlorophyll reside. Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules. These store energy in their bonds, which can be released in respiration in the mitochondria.

A ____ is a system that translates data from outside the nervous system into neural activity, thus giving the brain information

Kipish [7]

Answer;

- A sense

A sense is a system that translates data from outside the nervous system into neural activity, thus giving the brain information about the world.

Explanation;

-The sense or sensory nervous system is a part of the nervous system responsible for processing sensory information.

-A sensory system consists of sensory neurons, neural pathways, and parts of the brain involved in sensory perception. Commonly recognized sensory systems are those for vision, hearing, touch, taste, smell, and balance.

-Senses are transducers from the physical world to the realm of the mind where we interpret the information, creating our perception of the world around us.
