Answer:
Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere. This heat-trapping causes changes in the radiative balance of the Earth-the balance between energy received from the sun and emitted from Earth-that alter climate and weather patterns at a global and regional scale.
Multiple lines of evidence confirm that human activities are the primary cause of the global warming of the past 50 years. Natural Factors, such as variations in the sun's output, volcanic activity, the Earth's orbit, the carbon cycle, and others, also affect Earth's radiative balance. However, beginning in the late 1700s, the net global effect of human activities has been a continual increase in greenhouse gas concentrations.

GLUCOSE is an important source of fast, short term energy.
When energy is needed to carry out an intensive work that will last about two minutes, ATP can be generated form glucose via anaerobic process which is called anaerobic glycolysis. This process produces two molecules of ATP and two molecules of pyruvate from one molecule of glucose. The ATP produce is used to carry out the short term work.
Answer:
Option D, at the branch tips
Explanation:
Phylogeny tree is just like a family tree in which the roots of the tree that are its base represents the ancestral lineage. While moving towards the branches , the time is considered to be moving forwards as the organism which lie at the tip of the branches are the ones which have evolved from the ancestral lineage lying at the base. Thus, the branches at the end of a tree are the ones which have the most recently evolved organism.
Thus, option D is correct
Answer:
Water and ions are obtained from soil and glucose is obtained from leaves.
Explanation:
Water and ions are absorbed by the plant through roots from the soil whereas glucose is produced in the leaves during the process of photosynthesis. Vascular bundles such as xylem and phloem transported water, ions and glucose within the body. Xylem moves water from roots to the upper water of plants such as leaves, stem etc whereas phloem transported glucose from leaves to other parts of plant.
