Answer:
Tropism is the force used by the plants to grow in a specific direction.
Explanation:
The movement of plant parts such as shoots and roots etc in a specific direction in response to an external stimulus, this phenomena is known as tropism. Phototropism refers to the movement of upper part of plant body towards sunlight while on the other hand, the movement of roots downward against sunlight is known as geotropism. Both phototropism and geotropism are the types of tropism.
Answer:
Since a sample of air at 35 ° C and 60% relative humidity holds 26.25 grams / cubic meter of water vapor. The same sample of air at 40 ° C can hold a maximum of 50 grams / cubic meter of water vapor. If the air currently holds 30 grams / cubic meter, then its relative humidity is 60%.
Explanation:
To solve the following question, the following calculations must be performed:
If 40ºC can have a maximum of 50 grams per cubic meter of water vapor, this would imply a total of 100% humidity. Thus, if 35º had 100% humidity, the amount of grams per cubic meter of water vapor would arise from the following calculation:
40 = 50
35 = X
35 x 50/40 = X
1750/40 = X
43.75 = X
Now, if this implies 100% humidity, to determine 60% humidity the following calculation must be carried out:
100 = 43.75
60 = X
60 x 43.75 / 100 = X
2625/100 = X
26.25 = X
Therefore, if with 100% humidity you have 50 grams per cubic meter of water vapor, with 60% humidity you would have 30 grams of water vapor per cubic meter.
Answer:
Yes
Explanation:
The earthworm has a rounded dorsal (back) surface and a flatter ventral (belly) surface. Usually the dorsal surface is darker than the ventral surface (though sometimes this is obscured in the preservation process).
Digestion, medulla, heart, and involuntary muscles
The correct answer is: silent mutation
There are a few types of genetic mutation that can change genetic code. Those mutations can be classified:
1. Substitution-only one base is changed
• Nonsense mutations-when substitution leads to the formation of a stop codon instead of a codon
• Missense mutations-when one nucleotide is substituted and a different codon is formed
• Silent mutations-when a nucleotide is substituted and the same amino acid is produced
2. Insertion- extra base pairs are inserted
3. Deletion- section of DNA is deleted
