Answer:
This question lacks options, the options are:
A) Light-capturing pigment molecules in green plants absorb red, blue and violet light but reflect green light.
B) The energy of a photon of light is proportional to its frequency and inversely proportional to its wavelength
C) As light energy is converted to chemical energy by metabolic processes, some of the energy is lost as heat
D) Captured energy is stored in the molecular bonds of organic molecules, including simple sugars and starch
The answer is:
As light energy is converted to chemical energy by metabolic processes, some of the energy is lost as heat.
Explanation:
Green plants are capable of synthesizing their own food via a process called photosynthesis. The photosynthetic process uses light energy from the sun to form organic chemicals necessary for the growth and repair of plant tissues.
Plants are able to capture light energy from the sun using their chlorophyll pigment. Out of this captured energy, only a portion of the light energy captured by green plants is available for growth and repair. This is because as light energy is converted to chemical energy (stored in chemical bonds) by metabolic processes, some of the energy is lost as heat.
The correct answer is: A. minus end; dynein
Microtubules are cytoskeletal fibers that have an important role in the intracellular transport (movement of vesicles within the cell) and in the mitotic spindle during mitosis. The plus end of the microtubules extend through the periphery of the cells while the minus ends are anchored within the centrosome.
Necessary proteins for the vesicle’s movement are motor proteins:
• kinesin which is positive end directed
• dynein which is negative end directed
So, beside vesicles these proteins are also involved in organelles’ transport in opposite directions through the cytoplasm.
Answer:
Spinal cord
Explanation:
The PNS consists of the nerves and ganglia outside the brain and spinal cord.
Answer:
This statement is true, as the inner core is the most dense layer of the earth.
