Answer:
here.
Explanation:
The genes coding for colour show codominance. Both the brown and white pigment are equally expressed in the phenotype to give the tan colour.
Considering that the allele for brown pigment is CB and that for white pigment is CW, the genotype for the brown bird is CB CB and that for the white bird is CW CW.
Crossing CB CB × CW CW,
100% CB CW - tan-coloured birds
<h2>
Answer</h2>
Three types of covalent bonds, they can form
<h2>
Explanation</h2>
Carbon has four valence electrons in the outer shell but it forms three covalent bonds with another carbon atom. i.e Single bond, double bond and triple bond.
- The single bond is called Alkanes e.g. Methane, Propane etc.
- Double bonds are called alkenes e.g. Ethylene, Propylene etc.
- Triple bonds are called alkynes e.g. Ethyne, Propyne, Butyne etc.
The answer is <span>The respiratory system supplies the oxygen that the cardiovascular system transports to the different cells for the production of energy.
When air enters the lungs (part of the respiratory system), it passes all way to the alveoli, the smallest functional units of the lung. There, oxygen from the air enters the capillaries, the smallest blood vessels, next to the alveoli. Once in the blood stream, the cardiovascular system transports oxygen to different cells where it is used for the energy production.</span>
Answer:
In a habitat there are red bugs and green bugs. The birds prefer the taste of the red bugs, so soon there are many green bugs and few red bugs. The green bugs reproduce and make more green bugs and eventually there are no more red bugs.
C cells of the thyroid gland secrete calcitonin.
<h3>
What does C cells of thyroid gland produce?</h3>
- The thyroid follicle, which is the gland's active component, is encircled by a single layer of epithelial cells, and the lumen is stuffed with colloidal material.
- It includes parafollicular cells, or C cells, which release calcitonin.
- The C-cells of the thyroid gland secrete calcitonin, a 32 amino acid hormone.
- When the concentration of blood calcium has grown over the usual range, the thyroid gland releases the hormone calcitonin, which lowers the level.
- The parafollicular cells, sometimes referred to as the C cells, of the thyroid gland are the principal producers of this polypeptide hormone, which has 32 amino acids.
