Answer;
Retinohypothalamic path
A small branch of the optic nerve, known as the retinohypothalamic path extends directly from the retina to the SCN.
Explanation;
The SCN is an abbreviations for suprachiasmatic nucleus or nuclei; which is a region in the hypothalamus. that is responsible for controlling circadian rhythms.
Retinohypothalamic path is a neural input pathway that extends directly from the retina to the SCN.
The correct answer would be, B Kingdom Fungi to Eukaryota.
If u meant algae,
Algae form organic food molecules from carbon dioxide and water through the process of photosynthesis, in which they capture energy from sunlight. Similar to land plants, algae are at the base of the food chain, and, given that plants are virtually absent from the oceans, the existence of nearly all marine life—including whales, seals, fishes, turtles, shrimps, lobsters, clams, octopuses, sea stars, and worms—ultimately depends upon algae. In addition to making organic molecules, algae produce oxygen as a by-product of photosynthesis. Algae produce an estimated 30 to 50 percent of the net global oxygen available to humans and other terrestrial animals for respiration.

Pioneer species—first species to appear in primary succession. Usually lichens and mosses.
Climax community—the final stage in a succession. The plants tend to be larger and the community has the most biodiversity. ...
Biodiversity – different kinds (varieties) of life forms found in an area
Answer:
Option. A) 12
Explanation:
An organism with 24 chromosomes in each body cell will produce sex cells with 12 chromosomes. The chromosome number is half because meiosis occurs in sex cells in which parent cell is divided into four daughter cells having half number of chromosome i. e. haploid. So the parent cell has 24 chromosome when division occurs, the number of chromosome becomes half i. e. 12.
