Answer:
Until recent history,extinctions have always happened gradually and on a small scale.
Explanation:
Extinction occur when environmental factors like natural disaster,habitat fragmentation,over exploitation,global change don't favor the survival of species thus gradually leads to extinction of species.
Some times human activity becomes the major problem for extinction.More over,poor reproduction,decline in population number and genetic inbreeding also leads to extinction.
99% of all species that exist on earth become disappeared.
Evolution leas to speciation which leas to formation of new species but species become extinct when they are unable to survive against competition.
Answer:
A). True
Explanation:
tRNA, which means transfer RNA is one of the three types of RNA known in nature. The tRNA is found in the ribosome, where it plays a pivotal role in protein synthesis (translation). Transfer RNA is the RNA responsible for reading the nucleotides in the mRNA codon and carrying the amino acid that corresponds those codons to the ribosome.
The tRNA has a 3-dimensional structure that allows it to carry anticodon that reads codon and also carry amino acids on opposite ends. Hence, according to this question, tRNA is a type of RNA that delivers amino acids to the ribosome during protein synthesis.
Growth hormone- stimulates body cells to synthesize proteins and grow. Follicle- Stimulation hormone- stimulates the ovaries to develop mature eggs and stimulates the testes to produce sperm.
thyroid- stimulation hormone- stimulates the thyroid gland to secrete thyroid hormones
I kno dis because i did a quizlet on it :)
H O P E T H I S H E L P E D <3
The answer is B: Taxonomy allows a better understanding of relationships among species.
Don't worry the answer is correct. I did the quick check and got 100%
