The structure of an atom is best described as: 



1. neutrons in orbit about a nucleus of protons bound to electrons.

2. electrons and neutrons in orbit about a nucleus of protons
 

3. protons and neutrons in orbit about a nucleus of electrons .

4. electrons in orbit about a nucleus of protons and neutrons


Answers

Answer 1
Electrons in orbit about a nucleus of protons and neutrons
Answer 2

Answer: Option (4) is the correct answer.

Explanation:

An atom consists of three types of sub-atomic particles which are electrons, protons, and neutrons.

Protons have a positive charge and neutrons have no charge. Whereas electrons have a negative charge.

Protons and neutrons are placed inside the nucleus of an atom. On the other hand, electrons revolve around the nucleus of the atom.

Thus, we can conclude that the structure of an atom is best described as electrons in orbit about a nucleus of protons and neutrons.

what is the central dogma of molecular biology

Answers

It is a two step process transcription and translation by which the information genes flow into proteins DNA to RNA protein. Transcription is the synthesis of a RNA copy of a segment of DNA. RNA is synthesized by the enzyme RNA polymerase.




The central dogma of molecular biology describes the process by which genetic information flows from DNA to RNA to proteins. It involves transcription and translation. Understanding this process is key to understanding how cells function and regulate activities.

The central dogma of molecular biology explains the flow of genetic information within a biological system. First articulated by Francis Crick, it states that genetic information is stored in DNA, which is then transcribed into RNA. This RNA is subsequently translated into proteins, which perform most cellular functions.

This fundamental principle involves two main processes:

Transcription: DNA is used to make RNA.Translation: RNA is used to synthesize proteins.

Understanding the central dogma is crucial as it encompasses how genes encoded in DNA result in functional proteins, allowing for cellular activities and regulation.

Answers

The Rhodophyta are red in color and Phaeophyta are green in color but Phaeophyta’s body may be filamentous or may show root like hold fast, stemlike stipe and leaf like blades. Many of them have air bladders which keep them afloat

We can differentiate between two algae type that contain similar pigments by paper chromatography.

Rhodophyta and Phaeophyta

Rhodophyta are red algae and are the oldest eukaryotic algae. In red color algae, phycobiliprotein is present as pigment.They are found abundantly in marine areas.Phaeophyta are brown algae in which the chlorophyll is covered with a pigment called fucoxanthin.

Thus, by chromatography we can find out which pigment is present in the species and easily find out the species of the algae.

in order to continually use the same area of land for agriculture, some farmers apply fertilizers to improve the level of nitrates in the soil. an alternative to this intensive use of fertilizer is to plow the roots of the leguminous plants back into the soil and leave the area unplanted for a season. why would a farmer use this alternative method and what would be the benefit of turning over the soil and leaving the old pant roots?

Answers

Ploughing and turning over the soil aerates the soil so the roots of plants are able to thrive well. Ploughing the roots of leguminous plants back to the soil returns nutritents and organic matter to the soil organically rather than using synthetic fertilisers which are potentially hazardous to the environment.
Final answer:

Farmers might choose to plow leguminous plant roots back into the soil and leave the area fallow to naturally replenish the soil's nutrients. This practice uses rhizobia, bacteria that fix nitrogen from the atmosphere into a usable form for plants. This alternative to synthetic fertilizers aids soil fertility and promotes sustainable farming.

Explanation:

To maintain the fertility of farming lands without a constant use of fertilizers, farmers can resort to an alternative method, such as plowing leguminous plant roots back into the soil and leaving the area fallow for a season. Leguminous plants interact with soil bacteria, known as rhizobia, in a symbiotic relationship to influence nitrogen fixation. This is the transformation of atmospheric nitrogen into ammonia, a compound that plants can easily utilize. The incorporation of legume roots into soil not only provides a natural and sustainable supply of nitrogen but it also improves the overall soil fertility due to the nitrogen left behind by the root system.

Shifting toward this practice of extensive or shifting cultivation involving various plots of land serves both the environment and the farmer. For one, it minimizes the use of chemicals and thus promotes the sustainability of agricultural practices. Moreover, leaving a plot fallow for a certain period allows the soil to regenerate and accumulate fresh nutrients naturally. Furthermore, turning over the soil and leaving the old pant roots enhances the nutrient content of the topsoil, making it more fertile for the next planting season.

What is one function of roots

Answers

to take in the minerals from soil

Answer: The correct answer is-

To take in minerals form soil.

Roots are the significant organs of vascular plants that are located below the surface of soil.

They have specialized adaptation in their structures that enable them to absorb mineral ions ( such as sodium, potassium, phosphates, nitrates, magnesium that are very essential for plant growth) and water from the ground.

For instance, some plants possess fibrous roots that increase the surface area for absorption of minerals and other plants have tap root system ( that penetrates deep down to access water reservoirs) with lateral branches.

wo events in space are described below. Event 1: The moon travels between the sun and Earth and prevents the sunlight from reaching Earth during daytime. Event 2: The moon moves into the shadow of Earth at night, and this makes it difficult to see the moon from Earth. Which event or events represent(s) a solar eclipse on Earth

Answers

The answer is Event 1. A solar eclipse occurs when the moon gets between the sun and Earth and blocks the sunlight from reaching Earth's surface during daytime, thus casting a shadow over Earth. A lunar eclipse as represented by Event 2 happens when the moon passes into the shadow of Earth at night and we can see the moon darken.

viruses do not have the ability to reproduce on their own, they need a blank

Answers

The sentence should read "Viruses do not have the ability to reproduce on their own, they need a host cell"

Final answer:

Viruses require a host cell to conduct replication, as they cannot reproduce on their own due to the lack of essential components and metabolic machinery. They use the host cell's resources to produce viral particles and exhibit specificity in infecting cells that possess the required viral receptors.

Explanation:

Viruses do not have the capability to reproduce on their own; they need a host cell to facilitate the process known as replication. Viruses are not considered living organisms since they lack essential components like a plasma membrane, cytoplasm, and ribosomes. Unlike cellular life forms, they cannot perform metabolic activities or maintain homeostasis independently. Therefore, they must infect a living host, which provides the necessary cellular machinery and metabolism for the virus to produce new copies of itself.

Once inside the host cell, a virus commandeers the host's ribosomes, enzymes, ATP, and other resources to produce viral particles. Viruses show specificity in the cells they can infect, which is often determined by the presence of specific viral receptors on the surface of the host cell. This specificity depends on the host's metabolic processes and gene expression, which ensure the necessary substances for replication are available.

Where is a subduction zone most likely to from?

Answers

Answer


At a convergent boundary.Explanation:

A subduction zone is the largest wreck scene on Earth. These lines indicate the crash within two of the planet's tectonic plates. The plates are pieces of crust that slowly move across the planet's cover over millions of years. Where two tectonic plates meet, if one or both of the plates are oceanic lithosphere, a subduction zone will form. An oceanic plate will soak back into the mantle. Remember, oceanic plates are made from mantle material at midocean ranges.

Final answer:

Subduction zones form at convergent plate boundaries, particularly where an oceanic plate meets a continental plate. They are areas of high seismic and volcanic activity. Examples include the Marianas Trench and the Chile-Peru trench.

Explanation:

A subduction zone is most likely to form at convergent plate boundaries, specifically where an oceanic plate meets a continental plate. In this scenario, the denser oceanic plate is forced under the lighter continental plate, creating a subduction zone. Subduction zones are sites of high seismic and volcanic activity. Notable examples include the >Marianas Trench in the western Pacific Ocean and the Chile-Peru trench in the eastern Pacific Ocean.

1. Describe the plants and animals that would be found at the “Young Forest Stage” of a forest ecosystem?


2. Crocodiles are one of the oldest species on the planet. They have adaptations that allow them to exploit many niches. Explain what behavioral and structural adaptations have contributed to their success.

Answers

Answer to question no. 1:

A forest is at its young stage when it’s hardly touched by human or any external or harmful intervention, leaving it as natural as it is. That means it is filled with healthy vegetation, saplings everywhere, mature trees, vines and shrubs.

In this very rich forest environment, many species of animals thrive.  Most of them would be endangered species of migratory songbirds, mammals like white-tailed deers or rare insects.

Answer to question no. 2:

Crocodiles are able to adapt in most areas and can live for a long period of time due to several factors:

1)     They are cold-blooded.  A cold-blooded animal would have very slow metabolism so they can live without food for many months.  One big meal can keep them full for a long time.

2)     They can survive both on land and water.

3)     Just like mammals, the crocodile’s heart has four chambers that allows them to control their body temperature at a constant level. This is why they are able to adapt in many places.

4)     Crocodiles have strong senses which makes them good hunters / predators

a.     Sense of sight: they can see underwater and have night vision

b.     Good sense of smell

c.      Sensory buds in their jaws that help them detect vibrations and movements
