Yes, because even though other trees produce more oxygen, the small trees will still produce some oxygen. On top of this there are more small trees than big trees, so even though they make less oxygen, in whole they end up making more when added together!
Answer:
a. Bands at 1kb, 6kb and 8kb
Explanation:
The EcoRI and BamHI are the restriction enzymes which cut the DNA sequence especially a plasmid at specific sites called the restriction sites.
The restriction enzymes produces bands of specific length therefore these restriction enzymes are used to estimate the approximate length of the DNA.
In the given question, the
1. EcoRI- produces two strands of 7 kb and 8 kb
2. BamHI- produces two strands of 1kb and 14kb
This shows that the length of DNA sequence is 15kb
But when the DNA strand are digested with both the enzymes simultaneously then it will produce three bands as:
i) 14 kb can be broken down in 2 bands of 6 kb and 8 kb
ii) 1 kb band is already produced by the Bam HI.
This shows that 1+6+8= 15 kb
Thus, Option-A is correct.
Carbohydrates are your main sources of energy. They are needed for operation of the brain, body, and inner organs.

Answer:
the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.
The correct answer is: c. chordates are more closely related to echinoderms than to arthropods
The Closest nonchordate relatives to Chordates are Echinodermata. Hemichordates (such as acorn worms) and Echinodermata form the Ambulacraria which is the sister phylum of the Chordates.
Echinoderms and chordates are both deuterostomes, but the differences are that Echinoderm possess bilateral symmetry only as larvae, they have tube feet and their bodies are supported by calcite skeletons.
