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.

What is nucliec acid?

Nucleic acids are large biomolecules that play essential roles in all cells and viruses. Nucleic acids are the main information-carrying molecules of the cell, and, by directing the process of protein synthesis, they determine the inherited characteristics of every living thing.

A major function of nucleic acids involves the storage and expression of genomic information. Deoxyribonucleic acid, or DNA, encodes the information cells need to make proteins.

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.

Is Earths global mean temperature changing? explain your answer the words TREND and FLUCTUATION.

Answers

Answer:

Yes the Earths golbal mean temperature is changing.

Explanation:

The global temperature record represents an average over the entire surface of the planet. The temperatures we experience locally and in short periods can fluctuate significantly due to predictable cyclical events (night and day, summer and winter) and hard-to-predict wind and precipitation patterns. The strong warming trend of the past four decades likely reflects a shift from comparable aerosol and greenhouse gas effects to a predominance of greenhouse gases, as aerosols were curbed by pollution controls, according to former GISS director Jim Hansen.

Identify the point where the common ancestor of the fly and spider would be located.

Answers

Answer:

The common ancestor of the fly and spider would be located in the closest where B and C converge.

Explanation:

In phylogenetic trees, two species are more related if they have a recent common ancestor. On the other hand, two species will be less related if their common ancestor is not a recent one and is located far away in the tree.  

In the phylogenetic tree, the taxonomic groups of interest are located in the extremes of the lines called branches. In the present example, the fly and the spider are the species located in the extreme of the branches. The ramification point, which is also called "node" or divergence point, represents the location of the most recent common ancestor.

In the example, the point where the branches B and C get united, is the place where their common ancestor is located.      

The red point in the attached file "tree1" shows you where it is located the common ancestor of the two species.
