When do light independent reactions occur

Answers

Answer:

Light-independent reactions are carried out in three steps, termed Calvin cycle collectively: carbon fixation, reduction reactions and 1,5-bisphosphate (RuBP) ribulosis. Even if the "dark" reactions are called, the Calvin cycle actually does not occur in the dark or at night.

Explanation:

This part of the nervous system regulates involuntary actions such as
heart function, blood pressure, breathing, digestion.

Answers

Autonomic nervous system is the correct answer.

I had a biology exam earlier this morning with this question.

The autonomic nervous system (ANS) is in charge of controlling involuntary processes such as digestion, respiration, blood pressure, and heartbeat. The sympathetic and parasympathetic nervous systems make up its two divisions.

Through the "fight or flight" response, the sympathetic nervous system prepares the body for emergency situations. It speeds up the heartbeat, constricts blood vessels, widens the airways and releases stress hormones. These responses improve physical ability and preparedness for potential threats.

In contrast, the parasympathetic nervous system encourages relaxation and energy conservation through the "rest and digest" response. It promotes digestion, lowers heart rate, and promotes restorative and recovery processes.

What evidence indicates that there is a competition taking place among the plants in a natural setting?

Answers

Answer: 1. Ability of some plants to grow taller than Thier counterparts for sunlight.

2. The ability to release toxic substances to avoid competition from other plants

3. The ability of the plant to extend its roots for water and nutrients.

Explanation: A natural setting occurs in the forest where plants depends on sunlight and nutrients and water from the soil for survival and growth without the interference of man.

Because of these, there would be competition as the resources are limited enabling only the stronger to survive and grow and such evidences can be seen in

1. Some plants grow rapidly and become taller, other have broad leaves than other plants in the competition for sunlight at the expense of other plants eg redwoods trees or oak trees.

2. Some plants have the ability to extend Thier roots as far as possible to get water and nutrients to ensure Thier survival and growth.

3. Some plants release toxins to the environmental to prevent other plants from existing close to them to compete with them. Eg sunflower.

for each of the following organisms, describe how digested food reaches their body cells: a hibiscus plant, a paramesium, a coral polyp, an earthworm, a mosquito a human ​

Answers

Answer:

Hibiscus plant: transported by the phloem

Paramecium: simple diffusion from the food vacuole into the cytoplasm

Coral polyp: diffusion from the gut to the body cells

Earthworm: transport through the blood

Mosquito: transport through the blood

Humans: transport through the blood

Explanation:

Digestion involves both mechanical and chemical processes to break up

food into smaller or simpler constituent parts that can be absorbed by the body.

Digestion is divided into external digestion and internal digestion.

External digestion involves digestion of food outside the body using digestion enzymes and then absorption into the body by diffusion.

Internal digestion is when food is ingested into the body, broken down by Digestive enzymes and juices and then absorbed into the body cells.

A hibiscus plant stores it's food as starch. When the stored food is needed, it hydrolyses starch into molecules small enough to pass through the cell membrane. The hydrolysed food molecules are then transported by the phloem to cells that need them for energy production.

A paramecium is a protist which feeds by endocytosis, i.e. sorrounding and digesting food in its food vacuole. The digested food diffuses through the cell

cytoplasm and mitochondria oxidise it to produce ATP.

A coral polyp is a marine invertebrate belonging to the phylum Cnidaria.

Cnidarians have a simple sac-like gut, with only one opening and one unspecialised gut chamber.

They do not have a circulatory system to deliver nutrients to the cells, instead digested food diffuses from the gut to the body cells.

An earthworm is an annelid and carries out internal digestion. Food taken in from the mouth is digested and absorbed by the intestines into the blood. The blood then carries the absorbed food to the earthworm’s body cells.

Mosquitoes both male and female feed on sap and nectar, aphid honeydew, and plant juices, but in many species the mouthparts of the females are adapted for feeding on the blood of other organisms.

Food taken in by the mosquito is digested in the mid-gut by digestive enzymes. The blood absorbs digested food from the mid- gut and carries it to its body cells.

In Humans, digested food molecules are absorbed in the small intestine into our bloodstream. The blood then carried digested food molecules around the body to the cells where they are needed.

Answer:

The correct answer for the fill in the blank is - A sequence of bases on the DNA that codes for a trait.

Gene is described as a segment of DNA ( deoxyribonucleic acid) that codes for a particular protein, which in turn corresponds to a trait/ characteristic of the living organism.

Gene is first transcribed into mRNA ( messenger RNA) through a process called transcription. mRNA is then converted into protein through a process called translation.

The protein thus formed corresponds to a particular trait ( like eye color, hair color).
