Nutrient transport in the biosphere differs from energy transfer because, whereas energy travels through the biosphere and could be reused, elements continuously recycled.

The biosphere, often known as that of the ecosphere, is the totality of all ecosystems on the planet. It is also known as the zone sustaining life on Earth. In terms of matter, the biosphere is essentially a closed system with very few inputs and outputs.

Energy enters the environment from the Sun as well as exits when the organisms have consumed all of it. Heat is the form in which organisms transfer energy to the biosphere.. Energy additionally enters the biosphere from the Earth's interior. It is typically in the form of heat, rather than the electromagnetic energy emitted by the Sun.

The part of an amino acid that has the greatest influence on the overall structure of a protein is the side chains.

Proteins are one of the four basic macromolecules (the rest being carbohydrates, lipids and nucleic acids) that make up living things. It is made up of units of monomers called amino acids.

Each amino acid consists of an amino group attached to the alpha carbon of a carboxylic acid. In simpler terms, an amino acid is made up of a carboxylic acid, an amino group, a hydrogen atom and a side chain. The properties of the side chain determine the structure of the protein it forms.

Differences in properties of amino acids arise from the different size, shape, ionization properties and solubility of its side group. Depending on this, an amino acid can be polar, non-polar, polar but not charged, positively or negatively charged at neutral ph.

Mutations can affect chromosome number or structure. Among these last ones, deletion and duplication affect affect the number of genes. Translocation and inversion affect gene sequences. A) Translocation B) Deletion C) Inversion D) Duplication.

DNA suffers different mutations and changes. These mutations might affect chromosomes by altering a gene sequence or a chromosomal fragment.

There are two types of chromosomal mutations which depend on the mutation type,

-  If the mutation affects the number of the chromosomes (haploidy, polyploidy, aneuploidy)

- If the mutation affects the chromosome structure.

Among the mutations that affect the structure of the chromosome, we can mention,

- Deletion ⇒ Occurs a loss of genes

- Duplication ⇒ The number of genes increases

- Inversion ⇒ genes order or sequence is inverted

- Translocation ⇒ genes are interchanged between chromosomes

In the exposed example,

A) Translocation    

There was an interchange of genes between the two involved chromosomes.

One of them started with genes ABC and the other one with genes DE. After the interchage one of them ended with genes AC and the other one with genes DBC.

B) Deletion

The chromosome lost the A gene, which was deleted from the original sequence.

C) Inversion

The original sequence in this chromosome was ABC, and after the inversion the gene order was CBA.

According to the equation of the seismic waves, the earthquake's epicenter from the seismometer is approximately 5000km.

A seismic wave can be described as a vibration generated by an earthquake, explosion, or similar energetic source and propagated within the Earth or along its surface.

From the question, we have that

S-P interval = 0.001613 x distance

therefore distance =  s-p interval/0.001613

8/0.001613 = distance to epicenter

distance to epicenter =8÷0.001613

=4959.702

approximately 5000km.

Seismographs are devices that record the amplitude and frequency of seismic waves and yield information about the Earth and its subsurface structure.

There are several different kinds of seismic waves, and they all move in different ways.

The two main types of seismic waves are body waves and surface waves. Body waves can travel through the Earth's inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes send out seismic energy as both body and surface waves.

The equation for the mentioned set of points (2, -8), (6, 10) will be as follows:

Remember the slope-intercept equation: y =  mx = b

To solve this, first we will need to calculate the slope and y-intercept (b).

Equation for slope (m) is,

[tex]m =\frac{ (y_{2} - y_{1})}{(x_{2} - x_{1})}[/tex]

= [tex]\frac{10 - (-8)}{6-2}[/tex] = [tex]\frac{18}{4}[/tex] = [tex]\frac{9}{2}[/tex] = 4.5

Now, to write an equation for a line,

y = mx + b

where,

m = slope

b = y-intercept

So,

y = 4.5x + b

Putting the values of (x,y) = (6,10) to get the y-intercept,

10 = (4.5 x 6) + b

So, b = 10 - 27 = -17

Hence, the equation of line will be,

y = 4.5x - 17

or, y - 4.5x = -17

or, 4.5x - y = 17

or, 9x - 2y = 34

So, the correct equation for the mentioned two points will be 9x - 2y = 34.

Answer:

In order to perform karyotype analysis, chromosomes are obtained from actively dividing cells and treated with chemicals to keep them at the _metaphase_ stage of mitosis.

Explanation:

A phase of cell division known as "metaphase" (mitosis or meiosis). Many chromosomes are often spread throughout the cell nucleus. The cell's chromosomes compress and migrate toward one another, uniting in the center of the dividing cell, while the nucleus of such cell disperses during metaphase. All chromosomes may now be identified when examined under a microscope. During karyotyping, a clinical method for detecting chromosomal mutations, metaphase chromosomes are usually utilized. Several more years earlier we realized what kind of material was, the ability of the microscope to observe chromosomes during metaphase enabled us to recognise them as having genetic information.

Answer:your answer is haploidy. you are correct

Explanation:

In ionic bonds there is a transfer of electrons between two atoms having charge differences, whereas in covalent bonds there occurs an equal sharing of electrons between two atoms.

Ionic bonds is formed when transfer of electrons happen from one atom to other. The atom receiving the electron is electronegative whereas the atom donating the electron is electropositive. This, the two atoms are opposite in charge.

Covalent bonds are formed when electrons are shared between two atoms having no or negligible charge differences. Such atoms maintain an equilibrium between the attractive and repulsive forces. Covalent bonds cannot conduct electricity.

True is correct option.

Two alleles for a particular gene in a diploid organism are expressed and interact to produce a physical trait. The observable traits expressed by an organism are called its phenotype.

The underlying genetic make-up of an organism, consisting of both  physically visible and  non-expressed alleles, is called its genotype. Mendelian hybridization experiments demonstrate phenotypic and genotypic differences. For example, the phenotype that Mendel observed in  crosses between pea plants with different traits is associated with the diploid genotype of  plants in the P, F1, and F2 generations. As an example, we will use the second trait that Mendel studied, the color of a species. Seed color is determined by her one gene with two alleles. The yellow seed allele is dominant and the green seed allele is recessive. When a true breeding plant with one parent having yellow seeds and one  green seed was cross-pollinated, all his F1 hybrid progeny had yellow seeds. That is, the hybrid offspring were phenotypically identical to their purebred parents with yellow seeds. However, we know that the allele contributed by the green seed parent  was not simply lost, as it reappeared in some of the F2 progeny.

Therefore, F1 plants must have been genotypically different from their yellow-seeded parents.

Answer: Donates hydrogen ions to the solution

Explanation: According to Bronsted and Lowry, acids are the species that dissociate in water to give hydrogen ions.

Whereas bases are the species that dissociate into water to give hydroxide ions.

Also, like dissolves like. So, when an acid is polar in nature and dissolved in water then it will completely dissociate into ions.

As a result, it will tend to donate hydrogen ions into the solution.

For example, HCl ->H^+ +Cl

Thus, we can conclude that an acid is a polar substance that dissolves in water and donates hydrogen ions to the solution.

Lungs evolved from the extension of the esophagus rather than as a system of separate organs is the likely phylogenetic explanation for the crossing of food and air path routes in humans.

Evolving of lungs from the continuation of oesophagus makes an evolutionary sense for the nose along with lungs to have a path of their own whereas the mouth, as well as the stomach, consists of a separate system. This is created as if this would prevent the choking effect so that this can allow the breathing process while eating or drinking purposes.

In general, it might take a more logical sense of having a  separate passage route for air as well as food or water. This exactly did not happen as in evolutionary history due to the major peculiarity of the development of lungs. Outpouching of the gut tube is the development of lungs in vertebrates, due to a very long history of evolution in itself which might be homologous present among all deuterostomes.

So, lungs evolved from the oesophagus extension is the phylogenetic explanation for the crossing of food and air path routes in humans.

There are many evidences that might have helped scientists to be a cause for origin of water on earth . Possible reasons include:

A fraction of the water on Earth may have been created via gradual "dehydration melting"—leakage of water contained in the hydrate minerals of the planet's rocks. Water may have also come via volcanism: water vapor from volcanic eruptions in the atmosphere may have condensed into rain, which gradually filled Earth's marine basins.

These might be the possible evidence for the origin of water on Earth but it is still unclear where Earth's water came from or why there is unmistakably more liquid water on Earth than on the other stony planets in the Solar System.
