Biological processes that systematically vary over a 24-hour cycle are called circadian rhythms and are regulated by a cluster of neurons called the suprachiasmatic nucleus.

<h3>What is the circadian rhythm?</h3>

The circadian rhythm refers to the biological process regulated by the duration of a calendar day, which is common for many organisms ranging from animals to plants.

The circadian rhythms enable the maintenance of homeostatic control of physiological functions and thus perform metabolic activities.

In conclusion, biological processes that systematically vary over a 24-hour cycle are called circadian rhythms and are regulated by a cluster of neurons called the suprachiasmatic nucleus.

Match the gastric phase on the left (1-3) with the correct description on the right (4-6):
dem82 [27]

Answer:

1 and 5,

2 and 6,

3 and 4

Explanation:

Intestinal phase: stomach empties and decreases secretions

The intestinal phase is the phase where stomach empties its contents(chyme) and decreases secretion. In this stage the duodenum responds to arriving chyme and moderates gastric activity through hormones and nervous reflexes.

The Chyme is the semi-fluid mass of partly digested food that is expelled by the stomach, through the pyloric valve, into the duodenum.

Gastric phase: stomach secretes juice and mixes food into chyme

The gastric phase is a period in which swallowed food and semi-digested protein ( peptides and amino acids ) activate gastric activity  which secretes juice and mixes food into chyme. About two-thirds of gastric secretion occurs during this phase.

Cephalic phase: prepares stomach for arrival of food

The cephalic phase of digestion is the gastric secretion that occurs prior to when food enters the oral cavity. Cephalic phase result from the ignition of  visual, olfactory, and auditory inputs to the brain and also induce anticipatory responses i.e  prepare the gastrointestinal tract for the meal.

Dvinal [7]

The evolution of the jaw contribute to diversification of early vertebrate lineages is It made additional food sources available.

<h3>What is evolution?</h3>

Evolution is the shift in a biological population's heritable traits over successive generations. These traits are the result of genes that are expressed during reproduction and transferred from parent to offspring. Mutation, genetic recombination, and other causes of genetic diversity frequently result in different traits existing within a population. When these variations are subjected to evolutionary processes like natural selection (which includes sexual selection) and genetic drift, specific traits within a population start to become more or less prevalent. This is when evolution happens.

Which of the following is a nonpoint source of water pollution
Leokris [45]

<u>Answer:</u>

"Rainwater pouring from an eroded bank into a river" is a non-point source of water pollution.

<u>Explanation:</u>

Bank erosion is the washing away of stream or river banks. This is distinct from erosion of the watercourse bed, known as scour. These erosion undermines the roots of trees which develop by a lake. As the roots closely connect the soil, they form abutments that jut out above the surface.

Non-point source water contamination is induced by widespread and isolated waste sources such as rain and snowmelt runoff, spills, leaks, and sediment erosions. To release any pollutant, without a permit, from a point source into navigable waters is illegal according to the Clean Water Act.
