I think its C. hormones act on muscles and glands only. Because hormones act on cells, tissues, organs etc. So this is incorrect and the rest of them are correct.
A dominant allele will cause an organism to develop a certain characteristic whereas a recessive one won’t and it is represented as a lower case letter but dominant alleles are represented with a capital letter n
Answer:
Environmental hazards such as predators reduce the change if surviving into adulthood, Large amounts of gametes go unfertilised and wasted, Not guaranteed that sperm will come in contact with eggs, Greater chance of desiccation of gametes/zygotes.
Explanation:
Answer:
For the tRNA anticodon CCA the corresponding codon is GGU, which codes for the amino acid Glycine (Gly).
Explanation:
Transfer RNA or tRNA is responsible for driving the right amino acid into protein synthesis, once the mRNA codon has been translated by the ribosome. It is for that reason that each mRNA codon must have a complementary tRNA anticodon.
The RNA pairing rules is that each nitrogenous base has a complementary base, so:
- Adenine is complementary with uracil A=U
- Cytosine is complementary with Guanine C=G
In this case, it can be seen that:
- <em>For the anti-codon: CCA</em>
- <em>Codon: GGU</em>
- <em>Aminoacid: Gly</em>
Answer and Explanation:
Principal of Spiral plating:In the spiral plate technique, a mechanical plater vaccinates the fluid sample on a pivoting plate agar. The volume of fluid sample decline from the inside to the edge of the plate. The microbial concentration is controlled by checking the provinces on a piece of the Petri dish.
A technique, portrayed for deciding the quantity of microorganisms in an solution by the utilization of a machine which stores a known volume of test on a pivoting agar plate in a consistently diminishing sum as an Archimedes spiral.
Materials used: agar plates, dilution blanks, pipettes
Method:
A spiral plater is a gadget that disperses a constantly diminishing volume of fluid over a solitary pivoting agar plate (the apportioning arm moves like a needle on a turntable, just in reverse). The agar is then hatched and checks are made. It can viably convey up to a 105 concentration range on one plate, yet list requires an uncommon tallying lattice. After the example is brooded, distinctive state densities are clear on the outside of the plate. A changed checking matrix is portrayed which relates zone of the plate of volume of test. By checking a proper territory of the plate, the quantity of microscopic organisms in the example is assessed.
