The answer i believe is d.
hope this helps!!!
Answer:
1) In the first step, we need to predict the possible alleles for the cross. The dominant allele will be written with a capital letter. The recessive allele will be written with a small letter. Hence, the allele for brown hair colour will be B and the allele for red hair colour will be b.
2) In the second step, we need to determine the genotype of the parents. The genotype of the homozygous dominant parent will be BB. The genotype of the heterozygous brown hair colour will be Bb.
3) The punnet square for cross between these parents can be shown as follows:
B b
B BB Bb
B BB Bb
4) In the fourth step, lets determine the phenotype of the children. The phenotype of all the offsprings born will be brown hair colour.
5) The genotype from the punnet square shows that there is a 50% chance that the offsprings will be heterozygous dominant (Bb) for brown hair colour and their will be a 50% chance that the child born will be homozygous dominant (BB).
Answer:
The correct answer is- IgA
Explanation:
There are five types or class of antibodies found in the human body these are IgA, IgM, IgD, IgE, and IgG. Out of these five class IgA antibody is found in an abundant amount in the mother's milk or colostrum.
Infant take this antibody from the mother through breastfeeding which protects the infant from may pathogenic microbes. The immunity in which antibodies are taken from outside is called passive immunity.
Therefore the passive immunity source that is given by the mother to baby through breast milk is called IgA.
Gastric inhibitory peptide (GIP) a digestive hormone is secreted when fats and carbohydrates, especially glucose, enter the small intestine.
- A member of the secretin family of hormones, glucose-dependent insulinotropic polypeptide is an inhibitory hormone.
- It is sometimes referred to as gastric inhibitory polypeptide or stomach inhibitory peptide.
- The enteroendocrine K-cells, which are widespread in the small intestine secrete GIP.
- The hormone gastric inhibitory polypeptide, which is released by intestinal mucosal cells, prevents the stomach from producing hydrochloric acid.
- Additionally, it improves the islets of Langerhans' beta cells' ability to secrete insulin, which results in a considerable increase in blood insulin concentrations following oral glucose delivery.

The animals that live in the Alpine biome have to have special adaptations to survive in it as this is a biome with very harsh conditions for big portion of the year. The temperatures are very low, the winds are strong, winter lasts for half a year or more, and there's lot of snow. All this has made the animals to develop certain traits to help them survive. Some of those adaptations are:
- thicker and longer fur for better isolation form the outside conditions
- wider paws with denser and tougher skin, helping them to move easier in the snow and avoid frostbite
- larger lungs and nostrils for easier breathing in the high altitudes
- stockier bodies so that heat can be preserved easier
- the ears and tails are small and rounded in order to avoid frost bite
- big portion of them are able to hibernate for several months
