1. Describe the course of the water cycle which formed in Biosphere 2
2. Deduce what would happen if you were to store your “Biosphere X” in the dark for a few weeks.
Answers
1) Solution
The sun warms the ocean surface and other surface water, causing liquid water to evaporate and ice to sublime. It turn directly from a solid to a gas. These sun driven processes move water into the atmosphere in the form of water vapor.
2) Solution
If we store the “Biosphere 2” in the dark for a few weeks, the water vapour will condense to form water.

Adrenergic receptors Select one: a. can be activated by the release of epinephrine. b. have two structural forms - muscarinic and nicotinic. c. when activated stimulate skeletal muscles to contract. d. can be found in both the sympathetic and parasympathetic divisions. e. are activated by the release of acetylcholine.
Answers
Answer:
The correct answer is a. can be activated by the release of epinephrine.
Explanation:
Epinephrine is a hormone and neurotransmitter naturally secreted by the body through the adrenal glands, synthesized and stored in the adrenal medulla and released into the systemic circulation. Epinephrine is a non-selective adrenergic agonist, stimulating alpha1-, alpha2, beta1, and beta2-adrenergic receptors. The systemic actions of catecholamines are mediated by the binding of these compounds to plasma membrane receptors, of the GPCR type widely distributed throughout the body and known as adrenergic receptors, which are activated by the catecholamines adrenaline (epinephrine) and noradrenaline . These receptors cause different effects depending on the G protein subtypes to which they are associated and the signal transduction mechanism linked to the specific G protein.

Three potted plants were kept in a dark cupboard for two days before being used for an experiment. Each plant was then put under a bell jar under different conditions for six hours . Bell jar D contains a potted plant with a small cup of sodium hydroxide solution with light pointed towards it Bell jar E contains a potted plant with light pointed towards it Bell jar F contains a potted plant with aluminium foil on top of the bell jar with light pointed towards it a)explain why their was no starch in the leaves at the end of the two days in the cupboard b)what is the purpose of sodium hydroxide put under bell jar in D?
Answers
Answer:
a. There were starch in the leaves at the end of two days in the cupboard because there was no sunlight to provide the energy for photosynthesis in the dark cupboard. Also, any previously synthesized starch in the plant leaves were used by the plant for its own metabolic requirements during the period the plant was in the cupboard. Therefore, staying in the cupboard for two days destarched the leaves.
b. The purpose of sodium hydroxide put under bell jar in D is to remove any carbon dioxide that may be present under the bell jar. This is to demonstrate that even in the presence of sunlight, carbon dioxide is required for photosynthesis to occur in plants.
Explanation:
Photosythesis is the process by which green plants manufacture their food (carbohydrates which are stored as starch) in the presence of sunlight. The site of photosynthesis in plants is the leaves.
The experimental design is to study the conditions necessary for photosynthesis to occur. For photosynthesis to occur, there must be presence of sunlight, carbon dioxide and water. Carbon dioxide and water serve as the raw materials for photosynthesis while the energy required is provided by sunlight.
The answers to the observations from the experiment are given below :
a. There were starch in the leaves at the end of two days in the cupboard because there was no sunlight to provide the energy for photosynthesis in the dark cupboard. Also, any previously synthesized starch in the plant leaves were used by the plant for its own metabolic requirements during the period the plant was in the cupboard. Therefore, staying in the cupboard for two days destarched the leaves.

Answers
Answer:
Animals evolved during the Cambrian Explosion because oxygen on Earth had become abundant.
Explanation:
Photosynthesis could be responsible for the rise in the amount of oxygen in the seas and atmosphere near the beginning of the Cambrian. This rise of oxygen concentration allowing the evolution of larger animals having complex respiratory and circulatory systems. So we can conclude that evolution in the physical and genetical characteristics of animals occur during the Cambrian Explosion.

B. have to find a partner
Explanation:
When two badgers get together and fall in love, a sperm cell from the father which contains a copy of half of his DNA, only half, combines with the egg cell of the mother, which contains half a copy of her DNA. The result is a brand new cell with all the information to divide and grow up into a brand new badger. The new child matures to be similar to our parents, but also unique, because she developed some traits from her mother’s DNA, and some from her father. Her new combination of traits can be passed on to her children, and again.

Erosion and water pollution from mining operations C. Both A and B are correct D. Neither A nor B are correct
Answers
Answer:
C. Both A and B are correct
Explanation:
Coal is one of the important fuel for the generation of electric energy in the steam generator. Coal is mined from the coal mines and is fed into the steam generator to produce steam that is used to generate electricity.
The mining of coal can affect the environment nearby as it destroys the forest cover or trees nearby. It leads to erosion and water pollution. Also the carbon emission from the burning of the coal releases harmful pollutants inn the atmosphere which causes air pollution.
Thus both options (A) and (B) are correct.
