Answer: f. only b. and c. are examples of homozygotes
Explanation:
Diploid cells (all non-reproductive cells) have two copies of each gene, called <em>alleles</em>, one obtained from the father and one from the mother. In genetics, an organism is a homozygote for a gene if both alleles are the same. In contrast, heterozygotes have different alleles for the same gen.
Genes are represented with a letter, and you can differentiate between <em>alleles </em>if the letter is uppercase or lowercase.
For example, if you wanted to represent the gene that encodes a flower color, you could call A the 'red' version of it and a the 'blue' version of it. A plant would be homozygote for that gen if it had the same version for both alleles, AA or aa.
Answer:
B. Sodium ions directly enter the cells, indicating the signal is transduced by an ion channel.
D. Sweet utilizes the GPCR signaling pathway, activating phospholipase C.
Explanation:
The taste received by the taste buds is processed through different channels
a) The Sweet, bitter, and umami tastes are transduced by the GPCR (G-protein-coupled receptors) signaling pathway
b) Sour taste reaches the taste bud through the acidification of acid-sensitive membrane proteins with in the taste cell
c) The epithelial sodium channels in the renal tissues directly takes up the salty taste
Hence, option B and D are correct
0.00 meters as he went straight from the food source to his nest and back. It'd be different if he took a turn somewhere and took a longer/shorter route.
