Answer:

Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved. Fossils provide evidence of long-term evolutionary changes, documenting the past existence of species that are now extinct.

To give one classic example, the forelimbs of whales, humans, and birds look quite different on the outside. That's because they're adapted to function in different environments. However, if you look at the bone structure of the forelimbs, you'll find that the organization of the bones is remarkably similar across species. It's unlikely that such similar structures would have evolved independently in each species, and more likely that the basic layout of bones was already present in a common ancestor of whales, humans, and birds.

Respiration (both aerobic and anaerobic) begins with glycolysis in the cytoplasm of a cell;

1 glucose molecule (C₆H₁₂O₆) is converted into 2 molecules of pyruvate in a 10-step process, consuming 2 ATPs and yielding 4 ATPs;

Additionally, 2 NAD+ molecules are reduced to NADH molecules;

In aerobic respiration, each pyruvate molecule then goes through the link reaction, getting converted to acetyl co-A in the mitochondrial matrix, producing 1 CO₂ molecule and 1 reduced NADH molecule;

Acetyl co-A then enter the Krebs or tricarboxylic acid cycle (TCA) where 2 CO₂, 1 ATP, 3 NADH (by reduction of NAD+) and 1 FADH₂ molecules are produced;

The NADH and FADH₂ molecules produced are electron carriers required for the electron transport chain (ETC);

The electron transport chain consists of 4 proteins within the inner mitochondrial membrane which are involved in the production of ATP by oxidative phosphorylation;

The first protein (C1) is responsible for oxidising NADH to NAD+, releasing energy used to generate the proton motive force (PMF) by pumping the protons (H+ ions) into the intermembrane space and the electrons released are transferred to a ubiquinone molecule;

The second protein (C2) is responsible for oxidising FADH₂ to FADH, also releasing energy used to generate the proton motive force (PMF) and, similarly to C1, the electrons released are transferred to ubiquinone;

The third protein complex (C3) transfers the electrons from ubiquinone to cytochrome C;

Finally, cytochrome C transfers these electrons to the fourth complex (C4), where they combine with free protons in the matrix and O₂ to to produce H₂0;

The PMF is then harvested via an ATP synthase protein where H+ flood back into the mitochondrial matrix, and the energy released is used to generate ATP from ADP and Pi;

ATP is now ready for use for bodily processes requiring it.

Answer:

through a tiny hole or slit in a metal plate to isolate light from a single area or object.

The light from the lightbulb, as it passed through the spectroscopy telescope, underwent a process of dispersion. This resulted in the separation of the light into its component colors, forming a spectrum.

When light from a source like a lightbulb passes through a spectroscopy telescope, it encounters a prism or a diffraction grating. These optical components disperse the light based on its wavelengths. As a result of dispersion, different colors that make up the light are bent by varying amounts, causing them to spread out.

This separation of colors forms a spectrum, known as a continuous spectrum. This spectrum acts as a fingerprint, revealing the unique composition of the source's light, enabling scientists to analyze the elements or molecules present in the source material.

From the distances between genes and their order, it is possible to get recombination frequencies per region (simple and double recombination frequencies). The probability of obtaining a unc-32 vab-7 + offspring is 0.09 = 9%.  

---------------------

We are usually asked to get the order of genes in a chromosome. To do so, we need to get the distances between genes. And to get distances between genes, we need to get their recombination frequency.

When three genes are involved, we get the distances by taking the recombination frequency, P, per region.

We talk about regions, R, when we are making reference to the space between two genes.

                Gene 1 -----(R1)----- Gene 2 --------(R2)------ Gene 3

                                    P1                               P2

⇒  P1 = (SR + DR) / N

⇒  P2 = (SR + DR)/ N

Where:

The genetic distance will result from multiplying that frequency by 100 and expressing it in map units (MU). One centiMorgan (cM) equals one map unit (MU).  

In the exposed problem, we need to do the inverse way. We already have the order and distances between genes, and we need to get the recombination frequency, P.

We know that the order of genes is as follows,

unc-32 ------------- vab-7----------------- dpy-17

Distances are:

We need to get the probability of obtaining a phenotypic unc-32 vab-7 + offspring from a cross between a heter0zyg0us fly (unc-32 vab-7 dpy-17/ + + +  ) and the triple recessive nematode (unc-32 vab-7 dpy-17 / unc-32 vab-7 dpy-17).

Cross:  

unc-32 vab-7 dpy-17 / + + +     x     unc-32 vab-7 dpy-17 / unc-32 vab-7 dpy-17

To get the genotype unc-32 vab-7  + , a simple recombination, SR, must occur in region 2.

So we need to get the simple recombination frequency in Region 2.

To do so, first we need to clear the following equation

Distance between vab-7 dpy-17 = P2 x 100 = 20 MU

20MU = P2 x 100

P2 = 20  / 100

P2 = 0.2

The recombination frequency in region 2 (P2) is 0.2.

Now, we need to get the simple recombination frequency in this region.

P2 = (SR + DR) / N

P2 = Simple recombinants Frequency + Double recombinants Frequency

P2 = Simple recombinants Frequency + Double recombinants Frequency

0.2 = Simple recombinants Frequency + 0.02

Clearing the equation,

Simple recombinants Frequency = 0.2 - 0.02 = 0.18

Simple recombinant frequency in region 2 will produce the following two chromosomes,

So half of this frequency will produce one chromosome, and the other half will produce the other chromosome.

So, the probability of obtaining a phenotypic unc-32 vab-7 + offspring is 0.09 = 9%.

Explanation:Carrying capacity is characterized as the maximum populace size that a domain can continue inconclusively.  For most species, there are four factors that factor into figuring the carrying capacity of an individual population: food accessibility, water resources, habitat, and ecological conditions.

In a graph representation of population size in a time period increases until it reaches carrying capacity, carrying capacity is representing in the graph where the increase in curve becomes stable and makes a plateau.

Explanation:

Answer:auditory tube

Explanation

The structure that regulates air pressure between the external atmosphere and the middle ear cavity is known as the Eustachian tube.

The ear is a type of organ of hearing and balance which consists of a cavity in the skull structure lined with soft tissue. It surrounds three distinct spaces filled with air or fluid i.e. the outer, middle, and inner ear. These specialized spaces host both the sound transmission apparatus and the sensory apparatus.

Types of bones present in the ear are

1. Hammer shaped bone known as malleus which is attached to the eardrum.

2. Anvil shaped bone known as incus present in the middle of the chain of bones.

3. Stirrup shaped bone known as stapes is attached to the membrane-covered opening which connects the middle ear with the inner ear (oval window).

The cavity of the middle ear is a narrow air-filled space which is a slight constriction divides it into an upper and a lower chamber known as tympanic cavity proper below and the epitympanum above. The main function of the Eustachian tube is to equalize the air pressure between the environment and the middle ear.

Thus, the structure that regulates air pressure between the external atmosphere and the middle ear cavity is known as the Eustachian tube.
