Answer:
Newton's law of gravitation, statement that any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them
uhhhhhhhhhhhhhhhhh thanks
Alpha particles bouncing off gold foil in Rutherford's gold-foil experiment which developed the understanding of the structure of the atom, expanding upon Thomson's research with cathode rays.
The correct answer is A. Vascular tissue
Explanation:
The vascular tissue refers to different cell types that form conduction structures in vascular plants and whose main function is to transport substances such as nutrients, water, and minerals that support functions in the plant including photosynthesis. The two main structures that are part of this are the xylem that transports from elements from the roots to the leaves and the phloem that transport substances from leaves to the roots. Additionally, the xylem is composed of cells called tracheids, vessel elements and the phloem is composed of sieve-tube cells and companion cells. Therefore, tracheids, vessel elements, etc are components of the Vascular tissue.
Answer:
It combine with hydrogen and two electrons form water.
It is necessary for our breathing.
Explanation:
Oxygen during cellular respiration is very important.
It combine with hydrogen and two electrons form water.
It is necessary for our breathing. cellular respiration take place effectively in the presence of oxygen and produced more ATP.
There are two types of respiration:
1. Aerobic respiration
2. Anaerobic respiration
Anaerobic Respiration
It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.
Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide
Aerobic respiration
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
Glucose + oxygen → carbon dioxide + water + 38ATP
