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.

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.

What are two factors that determine an object's thermal energy?

Answers

Answer: MASS AND TEMPATURE

An object's thermal energy is dependent upon its temperature and mass. The higher the temperature of a given quantity of a substance, more is its thermal energy. Similarly, for the same temperature, higher mass of a substance will contain more thermal energy.

Explanation:

Two factors that determine an object's thermal energy are Mass and temperature.

Mass:

The mass of an object influences its thermal energy. The greater the mass of an object, the more thermal energy it possesses. This is because a larger mass contains a larger number of particles that are in motion, contributing to the overall thermal energy of the object.

Temperature:

The temperature of an object is a measure of the average kinetic energy of its particles. The higher the temperature, the greater the average kinetic energy and thus the greater the thermal energy of the object. Temperature determines the intensity of the thermal energy and how vigorously the particles are moving.

Thus, mass and temperature, play significant roles in determining the thermal energy of an object.

Since a scratch was produced with Chalcopyrite, Pyrite and Orthoclase but not on Quartz, clearly Quartz was the hardest mineral of the minerals that were tested.  To prove this, we can search up the hardness of each mineral.  Quartz on the hardness scale is 7, Orthoclase on the scale is 6, Pyrite is 6 and Chalcopyrite is 4.  Quartz being the highest at 7 is the hardest of the minerals

What are the similarities and differences between a predator-prey relationship and a herbivore-plant relationship?

Answers

Answer:

Predator-prey relationship and a herbivore-plant relationship have some of the similarities and some differences.

Similarities:

In both relationship,  Predator-prey and a herbivore-plant, the interaction is between two species in which one organism or species fed over other organism. in predator-prey relationship, predator is the species that fed over prey and in herbivore-plant relationship, herbivores are the species that fed over plants. So, both are type of predation .In both relationship, one species dependent on other for their survival or food.Both relationship controls the size of recessive species such as prey and plants in the environment.

Differences:

herbivore-plant has mutual interaction as herbivores eat plants and also helps plants to spread their seed and when animals die it decompose to the soil which is beneficial for plant growth while this is not same with predator-prey relationship, they have symbiotic relationship.In herbivore-plant relationship, the plants are unable to move in order to defend themselves except some mechanical advantages while in predator-prey relationship, prey can move themselves and fight for their survival

Hence,  predator-prey relationship and a herbivore-plant relationship have some similarities and differences as well.

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.

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.

Answers

Answer:

Tectonic plate motion causes changes in the sizes, shapes, and the positions of the Earth's continents and oceans. Thus, the correct option is D.

What is Tectonic plate motion?

Tectonic plates are the gigantic pieces of the Earth's crust and the uppermost mantle of the Earth. These layers of the earth are made up of oceanic crust and continental crust. Earthquakes mainly occurs around the mid-ocean ridges and the large faults which mark the edges of the plates in the Earth.

The heat from radioactive processes within the planet's interior causes these tectonic plates to move, which sometimes results towards and sometimes away from each other. This movement of the tectonic plates is called as plate motion or tectonic shift.

Therefore, the correct option is D.
