Which organism fix nitrogen in the soil ?

Answers

Answer:

Diazotrophs

Explanation:

The nitrogen-fixing bacteria and other micro organisms that fix nitrogen are collectively called 'Diazotrophs'. There are many strains of these bacteria in soil, which perform this function. They are important agents in the 'Nitrogen Cycle'.

There are two main groups of organisms that fix nitrogen in the soil: diazotrophs and cyanobacteria.

What are these organisms?

Diazotrophics are bacteria that can convert atmospheric nitrogen into ammonia, which is a form of nitrogen that plants can use. Some examples of diazotrophs include Rhizobium, which is found in the root nodules of legumes, and Azotobacter, which is a free-living bacterium.

Cyanobacteria are photosynthetic bacteria that can also fix nitrogen. They are found in aquatic and terrestrial environments, and they can play an important role in the nitrogen cycle.

What reasoning correctly pairs a body system with its relationship to the digestive system?

Answers

Answer:

Respiratory system.

Explanation:

This is the system which shows a good pairing with the digestive system. This is because for energy to be synthesized by oxidative phosphorylation,  respiratory systems need  the supply of  Oxygen. The oxygen is needed to accept the final electron in the synthesis of ATPs during oxidative phosphorylation.

This process begins with substrate level phosphorylation-glycolysis- the breaking down of glucose from the digestive system.

Hence, respiratory system needs  the  supply of oxygen for the metabolisms of glucose obtained from digestive system to generate energy( extract the energy in glucose) for the body.

CID is a neurological disease believed to be caused
by prions, pathogenic agents that are smaller than
viruses, and are extremely resistant to inactivation
by heat and disinfecting agents. The incubation
period can be many years long and death is almost
certain within a year after initial onset of symptoms. What is the Main Point and What is the sub points?​

Answers

Answer:

Main point: CID is a lethal disease caused by prions.

Sub-points:

CID is a neurological disease (this means that it affects the nervous system.)Prions are pathogenic agents (this means disease-causing or harmful) that are smaller than viruses.They are resistant to inactivation by heat and disinfecting agents (this means that they're really hard to kill, because they're technically just misfolded proteins.)The incubation period can be many years long. (as in, symptoms may not show for a long period, but the prions are sitting in your body incubating and biding their time.)There's a very high mortality rate a year after symptoms show.

Seif’s pet mouse had babies. Five of the babies were black and two were white. The father mouse was black. The mother mouse was white. Seif and his friends wondered why the mice were different colors.

These were their ideas:

Jerome: Baby mice inherit more traits from their fathers than their mothers.

Alexa: Te baby mice got half their traits from their father and half from their mother.

June: Male traits are stronger than female traits.

Seif: Black mice have more traits than white mice.

Fiona: The black baby mice are probably male and the white baby mice are probably female.

Lydia: Parent’s traits like fur color don’t matter—nature decides what something will look like.

Billy: Blood type determines what traits babies will have.

Which friend do you most agree with and why? Explain your thinking.

Answers

Answer:

Lydia

Explanation:

The black fur in mice is probably more the dominant-inherited trait. The white fur is probably a recessive gene so less of the baby mice will have white fur.

The characters of offspring is decided by their traits, which they get from their father and mother. Sefi's pet mice have different colors because it got half traits from mother and half from father.

What is genetic inheritance?

Genetic inheritance means transfer of characters from parents to offspring. Due to this reason, offspring have characters from both father and mother.

This process is based on Mendalian principle. Any character of offspring is determined by both father and mother, not from the single one.

Here, as the father mouse was black and the mother mouse was white, so according to Mendalian principal, there were difference in the colors of baby mice.

Thus, one should be agree with Alexa, who gave an idea that the baby mice got half their traits from their father and half from their mother.

Plan an investigation to determine which part of the oregano plant has the highest concentration of chemicals with antimicrobial properties

Answers

Answer:

The study reported here presents a comparative screening of three medicinal plants including oregano (Origanum vulgare L.), lavender (Lavandula angustifolia) and lemon balm (Melissa officinalis) having the same geographical origin, the Southeast region of Romania, and growing in the same natural conditions. The contents of total phenolics and total flavonoids for the extracts of these were determined. Furthermore, the total antioxidant capacity was also evaluated. It was found that Origanum vulgare and Melissa officinalis extracts present the most effective antioxidant capacity in scavenging DPPH radicals, while Lavandula angustifolia is less active. High performance liquid chromatography-mass spectrometry analysis was used to identify the components of extracts. Major phenolic acids identified in the analysed species were ferulic, rosmarinic, p-coumaric and caffeic, while predominant flavonoids were quercetin, apigenin kaempherol, which were present as glucosides.
