In recent decades, average global temperatures have increased significantly. Scientists agree that the widespread destruction of the Amazon rain forest contributes to climate change. Which mechanism might be cited to support that hypothesis? A Deforestation causes water on the ground to reflect sunlight.

B Deforestation reduces the number of plants able to absorb carbon dioxide.

C Photosynthesis produces energy, which gives off heat.

D Plants use up energy during cellular respiration.

The main reason causing average global temperature rise is increase in amount of green house gases like Carbodioxide, and since deforestation reduces a vast number of plants, so there is lack of plants absorbing CO2 causing this whole thing.

So, according to this the Correct choice is B

Option A : the fern transitined from gametophyte generation to sporophyte generation.

for six years an artificial fertilizer is used on a apple orchard the orchard is next to a stream which empties in to a slat water bay during the last 5 years researchers have observed an increase in algae in the bay they have also sampled fish populations in the bay each year apex...

Explanation: with a great tolerance to a wide range of conditions the species would adapt and thrive which would allow it to reproduce and have all it needs to survive, grow, and take over.

Need this store of protein: 

The seed consists of three components: embryo, endosperm (sometimes perisperm), and seed-coat. Both endosperm and embryo are the products of double fertilization, whereas the seed-coat develops from the maternal, ovular tissues. The seed habit is a significant advancement in the evolution of higher plants.

Anatomy of seed :-

Seed storage proteins provide a source of amino acids and reduced N necessary for germination and early growth of the seedling.

B)Phosphorus has a larger atomic mass.

As we move right in the periodic table, both atomic number and atomic mass increases. Magnesium comes under S-block elements (Group 2) and Phosphorus comes under P-block elements (Group-15).

The T-chart by categorizing each statement as something that would most likely be relevant to gene flow or genetic drift. Some answers will fit in both columns depending on the situation. is random is a mechanism for evolution is often related to disasters is also called “migration” deals with movement between populations...
