unique quantum numbers.

Answers

Answer:

Principal,subsidiary,magnetic,and spin quatum numbers

The given statement "The location of an electron in an atom can be described by  unique quantum numbers." is true.

Quantum numbers, a series of specific numbers to describe the location of an electron of a particular atom. Quantum numbers define the features of the atomic orbitals and the electrons filled in those orbitals.

An electron in an atom or ion has four quantum numbers to describe its state are principal quantum number, azimuthal quantum number, magnetic quantum number, and spin quantum number.The electrons filled in the associated atom in the order of increasing energy of orbitals.

 1s 2s 2p 3s 3p < 4s <3d <4p < 5s < 4d <5p < 6s <45 < 5 < 6p...

Principal quantum number: explains the energy level of an electron. It is denoted by n. Azimuthal quantum number: explains the sub-shell of an electron. It is denoted by l.  Magnetic quantum number: explains the energy levels of the sub-shell of an electron. It is denoted by -[tex]m_{l}[/tex]. Spin quantum number: explains the spin of an electron. It is denoted by [tex]m_{s}[/tex].

Please help

Answers

Answer:

Succession occurs after sudden catastrophic change.

Explanation:

In communities, organisms occupy specific niches. These gradually evolve over time as these organisms interact with their geosphere. In ecological succession, a community may undergo several dynamic changes. These include primary succession and secondary succession- these communities eventually try to achieve equilibrium over time.

After catastrophic events, the microorganisms, primary succession occurs. Here, a colonizing species exploits a non-habitable region. These eventually make the region more habitable through nutrient cycling, weathering, etc. which ushers in secondary succession. Here, the communities become more complex with time, becoming more varied and an increasingly large food web.

Bananas (and other fruits) change as they ripen.



What happens to the carbohydrate molecules in the fruit as they ripen?



1. Use the tests to identify how the 2 different carbohydrate molecules change in the banana from unripe to ripe. (You will need to run both the Carbohydrates tests - One that tests for glucose and one that tests for starch for BOTH the unripe banana AND the ripe banana and record the results below).



2. Based on how you like your fruit (ripe or unripe), make a claim about how each of the different molecules tastes (sweet or unsweet-- think about which carbohydrate tastes more sweet starch or glucose?).


HELPPPPPPPPPP

Answers

Answer:

What happens to the carbohydrate molecules in the fruit as they ripen?

During ripening, there is an increase in the breakdown of starch inside the fruit, and a corresponding increase in the amount of simple sugars which taste sweet, such as sucrose, glucose, and fructose. This process is particularly obvious in bananas as they ripen. Green bananas do not taste sweet at all, and the riper they get, the sweeter they taste. There is also a decrease in acidity as the fruit ripens and a decrease in bitter plant substances, such as alkaloids. Last, as fruits ripen they produce complex compounds that are released into the surrounding air, giving a ripe fruit its pleasant aroma.

The breakdown of complex carbohydrates in the fruits increases in the fruits as they ripen.

What happens to ripened fruits?

When fruits are growing on the plants, the plant is constantly providing them with water and nutrients for their development. Initially, the growing fruits are protecting the seeds inside them.

In the growing stage, fruits are not edible and do not attract predators. This allows the fruit and the seed inside it to develop properly.

After completion of seed development and the growth of fruit, it changes in appearance to attract consumers including birds, humans and animals.

The fruit also starts to get softer as the cell wall begins to break down. The cell wall is made up of complex carbohydrates with glucose as its monomer.

The cell wall is broken down by the protein enzymes that accompany the fruits as they ripen.

Therefore, the breakdown of complex carbohydrates in the fruits increases as they ripen.

Describe how the available energy in the marine ecosystem of the pacific northwest could be different than that of the african savanna

Answers

Savannah is located near the equator has more energy availability.

Maine ecosystem of the pacific northwest consists of open ocean and is influenced by the seasonal upwelling events and has freshwater and saline water bodies. It has an average temperature of 39 °F but is warmer near the equator.
While the African savanna is a tropical grassland ecosystem and has warm temperature year-round is characterized by grasses and dispersed trees.
The sunlight easily reaches the ground and the vegetation is dense and the climate usually warm with 20 to 30° C with an annual rainfall of 30 inches per year.

The available energy in the African savanna is  Higher than  the available energy in the Marine ecosystem

The African savanna is located closer to the Equator and maintains a temperature of around 20 to 30° C due to the availability of enough sunlight reaching the soil and the vegetation found in the African savanna. also there is enough rainfall all year round.

The availability of sunlight and rainfall year round makes the energy levels in the African savanna higher than the energy available in Marine ecosystem.

The Marine ecosystem which consists of Freshwater water and salt water bodies have less sunlight penetrating through them and this negatively affects the available energy ( chemical / heat ) present in the marine ecosystem.

Hence we can conclude that The available energy in the African savanna is Higher than the available energy in the Marine ecosystem.

Scientist claims that Elysia chlorotica, a species of Sea slug, is capable of photosynthesis. which of the following observations provides the best evidence to support the claim?
A) Elysia chlorotica will die if not exposed to light
B) Elysia Chlorotica grows when exposed to light in the absence of other food sources
C) Elysia chlorotica grows faster when exposed to light than when placed in the dark
D) Elysia chlorotica grows in the dark when food sources are available.

Answers

Answer:

The correct answer is - B) Elysia Chlorotica grows when exposed to light in the absence of other food sources

Explanation:

If placing Elysia Chlorotica in presence of the food sources in the presence or absence of light it still grows as normal. However, if placing in the light in absence of the food sources it should not grow if it is not able to perform photosynthesis but it does which means there is a photosynthesis process also involve in the Elysia.

Photosynthesis is the process that involves the production of energy and nutrition in presence of light with water and atmospheric carbon dioxide.

Elysia chlorotica is a mollusc that belongs to the species of green slugs. It is generally found in the coastal zones of the United States including New Jersey, New York, Texas and Florida.

The correct answer is:

Option B) Elysia Chlorotica grows when exposed to light in the absence of other food sources.

The explanation for the option is:

Some of the chloroplasts are stored in the digestive system, which sustains and keeps them alive for months for later use.

After some years these chloroplasts get deeply buried in the cells of the gut facilitating the slugs to remain green without feeding further.

This merger of mitochondria into the cells enables the slugs to capture the energy and allows them to make their food just like plant makes food from the process of photosynthesis.

Therefore, Elysia Chlorotica grows when exposed to light in the absence of other food sources as it makes its own food and energy.

Answer:

It is harmful because it obviously affects the plant’s ability to survive

Explanation:

Mutations are alterations in the genetic code that may occur due to environmental or chemical mutagens. Mutagens, are substances or agents that induce changes in the genetic code.

Photosynthesis is a complex biochemical process; plants convert solar energy into chemical energy as sugars like the polysaccharide glucose. They also use inorganic carbon from [tex]CO_{2[/tex] along with [tex]H_{2}O[/tex].

Plants photosynthesize in their leaves- these organs contain tissues for  [tex]CO_{2[/tex] intake, along with the chloroplasts and mitochondria, the sites of photosynthesis and respiration. If the number of leaves are reduced, this reduces the amount of tissue capable of carrying out this essential process, limiting the plant's chance for meeting its energetic needs, and thus survival.

Answers

Answer:

Explanation:

This is just Central Dogma. DNA (deoxyribonucleic acid) is transcripted into mRNA which goes to the Ribosomes where it is turned into polypeptides/protiens which code the body.

DNA is a molecule made up of  Deoxyribonucleic acid that is composed of two chains that coils are around themselves and form the double helix.

Within eukaryotic cells, DNA is organized into a strong structure called as chromosomes. These are duplicated in the cell formation process. Most organisms store their DNA in the cell nucleus. DNA is a long polymer made of repeating units. DNA is capable of coiling into tight loops and other shapes. As the genetic information is held within genes the genome encodes protein. Thus the DNA is a nucleus and can be transcribed in the mRNA which later eaves the nucleus and forms proteins. Hence the option A is correct.

Answers

Answer:

The open area where the substrate is attached to an enzyme is called the active site.

Explanation:

The active site of an enzyme corresponds to the place where the tertiary structure of this molecule leaves a free space to couple the substrate and be able to catalyze a chemical reaction.

Since the enzyme-substrate complex functions as a key lock system, the active site has a three-dimensional configuration that only admits certain molecules as substrate, which determines its specificity.
