Biological diversity is the variety of species in a given area. If a new species is added there are more species and therefor greater biological diversity and if one goes extinct there are less species and therefore less biological diversity.
Answer:
Separating a cell into 2 different parts allows for the creation of specific environments in a cell.
Explanation:
Separating a cell into 2 different parts allows for the creation of specific environments in a cell.One example would be Nuclear Envelope.The nuclear envelope is a double membrane Where the two membranes are separated by space.Another example would be the Endoplasmic Recticulum. The endoplasmic recticulum has two different parts which are the smooth er and the rough er. The smooth er is smooth at the top because it lacks ribosomes.The rought er is rough because it has studded ribosomes on the outer surface of the membrane.
Answer:
binding of the hormone molecule with its receptor of the cell.
Explanation:
Hormones are chemical messengers secreted or released by endocrine glands to effect a response in another location called target location. Hormones are proteinous molecules and like every other protein, its function is determined by its shape.
Hormones function or effect their changes by binding to the receptor of the target cell. The hormone recognizes and will only bind to its own receptor molecule on its target cell on order to bring about any change. This defines the specificity of the hormone.
Answer:
C. Hydrogen bonds
Explanation:
Anticodon refers to the set of three nucleotides present in tRNA. The anticodon is complementary to the codon of mRNA. The nucleotide bases of anticodon and mRNA codons are paired by hydrogen bonds.
Here, the adenine of anticodon makes the hydrogen bond with the uracil base of codon while the guanine base of anticodon forms the hydrogen bond with the cytosine base of the codon.
There is a specific tRNA with an anticodon complementary to the mRNA codon for each amino acid. For example, the tRNA for phenylalanine has an anticodon 3' AAG 5' and binds to the complementary mRNA codon base via hydrogen bonds.
A runaway greenhouse effect is a process in which a net positive feedback between surface temperature and atmospheric opacity increases the strength of the greenhouse effect on a planet until its oceans boil away. An example of this is believed to have happened in the early history of Venus.
