The Galapagos Islands were formed from underwater volcanic activity. The islands initially were barren, supporting no life, and then they went through a series of colonization stages. The equilibrium model of island biogeography states that the species composition on an island will constitute a balance between the immigration and extinction rates. Based on the equilibrium model of island biogeography, indicate if the following statements concerning succession on the islands are predicted to be true or false.

a. Species arriving later might outcompete earlier arriving species, driving them to extinction.
b. The number of species on an island decreases as a function of the distance from the source-pool (in this case, mainland South America).
c. The number of immigrants will increase the closer the island is to the source.
d. The rate of extinction will be lower on smaller islands due to small population sizes and less competition.

Answers

Answer:

a. Species arriving later might outcompete earlier arriving species, driving them to extinction. (True)

b. The number of species on an island decreases as a function of the distance from the source-pool (in this case, mainland South America). (True)

c. The number of immigrants will increase the closer the island is to the source. (True)

d. The rate of extinction will be lower on smaller islands due to small population sizes and less competition. (False)

Explanation:

The equilibrium model of island biogeography, from the question, states that the species composition on an island will constitute a balance between the immigration and extinction rates.

The succession on the island would be how the species composition on an island develops gradually with time.

So, species arriving later might outcompete earlier arriving species. As the Islands continue to develop, major players like the primary producers and other factors that aid ecological development would support the growth of species that would previously have struggled to live on the island.

The number of species on an island can also be determined by the distance from the source-pool (in this case, mainland South America).

The more the island gets food from a near source, the more the influx of those organisms to the island.

So many factors contribute to extinction, some include, natural disasters, evolutionary changes, loss of habitat. Small population sizes and less competition do not mean a lower rate of extinction.

g To use an electron microscope to view Corona Virus particles of 50 nm diameter, what can you say about the wavelength of the electrons

Answers

Answer:

The wavelength of the electrons are smaller than the wavelength of virus.

Explanation:

The wavelength of the electrons are smaller than the wavelength of virus that is responsible for the corona disease. Due to smaller wavelength, we can able to see view Corona Virus particles having diameter of 50 nm. Electrons have very lower wavelength as compared to light i.e. 100000 times shorter up to 0.004nm due to which we are able to see viruses through it so we can conclude that the wavelength of the electrons are much smaller than the wavelength of viruses.

If a region on earth has a TEMPERATE climate, which of the following
statements will be true about that region?
O The temperature is usually warm and it rains often.
O
The temperature is usually cold and it rains or snows often.
The temperature and rainfall change at different times of the year.
The temperature is usually cold and there is very little rainfall.

Answers

Answer:

The temperature and rainfall change at different times of the year.

Explanation:

A temperate climate region is a territory in which the climate cannot be classified as completely hot or cold, nor rainy or dry, but these characteristics are variable according to the season of the year in which it is found. Thus, these climates do not have extreme heat or cold temperatures, but rather moderate climatic conditions. An example of a region with a temperate climate is the Mediterranean region, the State of Georgia in the USA or Uruguay.

Nuclear hormone receptors form a complex with their ligands, other proteins, and DNA control elements in order to regulate the expression of specific genes. These nuclear hormone receptors have four principal domains. Categorize each trait according to the appropriate nuclear hormone receptor domain with which it is associated.

Answers

Answer:

Explanation:

Nuclear receptors are a type of protein that functions as an intracellular steroid and thyroid hormone receptor. The interaction of these hormones in conjunction with nuclear receptors changes the pattern of gene expression, allowing certain genes to be transcribed while others are silenced.

As a consequence, unique mRNA translation products, proteins, and, in most cases, enzymes are generated. Nuclear receptors connect to DNA directly and control the expression of certain genes, regulating the organisms growth, homeostasis, and metabolism.

The following domains are found in a normal nuclear receptor:

The amino-terminal activation domain contains the transcriptional activation mechanism and is strongly variable in sequence (AF1). The recruiting of coregulators is the domains key feature.

⇒ Activation function 1 (AF1); Coregulator recruitment

DNA binding domain: It is amongst the most closely conserved centrally located domains, with two zinc fingers that attach to specific DNA sequences known as hormone reaction components (HRE).

⇒ nine conserved cysteine residues; zinc finger domain; center of the receptor.

The hiinge domain serves as a versatile connection between the DNA binding and ligand-binding domains. It has a nuclear localization signal in it. ⇒ Nuclear localization signal

Ligand binding domain:  The sequence of the ligand-binding domain is moderately conserved throughout nuclear receptors. It denotes the carboxyl-terminal end of a ligand domain. It has hydrophobic steroid-binding pockets that draw the hormone and AF2 activation domains. It also attaches to proteins that serve as coactivators and corepressors.

⇒ binding of corepressor proteins;  steroid-binding hydrophobic pocket; AF2 activation domain; binds coactivators; carboxyl-terminal end

The sequence of DNA ACTGGGCGTAAG part of a gene. How many CODONS can be found in the segment

Answers

Explanation:

First, think about which base pairs arise in complementary strands of DNA:

DNA → DNA

adenine → thymine (A → T)

thymine → adenine (T → A)

cytosine → guanine (C → G)

guanine → cytosine (G → C)

However, mRNA does not consist of the same four bases as DNA. While DNA has the ATCG nitrogenous bases, RNA replaces thymine with uracil, making its bases AUCG.

So, that means that whenever DNA has adenine, instead of pairing this with thymine, RNA will use uracil instead.

DNA → RNA

adenine → uracil (A → U)

thymine → adenine (T → A)

cytosine → guanine (C → G)

guanine → cytosine (G → C)

Explain why serine proteases do not catalyze hydrolysis if the amino acid at the hydrolysis site is a D-amino acid. Trypsin, for example, cleaves on the CC-side of L-ArgArg and L-LysLys, but not on the CC-side of D-ArgArg and D-LysLys.

Answers

Answer:

Explanation:

A protease is an enzyme that catalyzes the hydrolysis of the peptide bonds that tie polypeptide chains together, releasing individual amino acid subunits. The L and D nomenclature for amino acids defines the structure of the glyceraldehyde isomer through which the amino acid can be produced.

SEE BELOW FOR THE APPROPRIATE STRUCTURES.

We need to figure out why swine proteases hydrolyze L-amino acids but not D-amino acids in any way. we know that enzymatic catalysts act as polypeptides if you can recall. They must retain a very precise three-dimensional structure for a catalytic activity to occur. Substrates that do not quite match the required configuration at the active site will not be reacted to — this is a "lock and key" style.

The present exercise may be explained by the fact that the configuration and structure of D-amino acids prevent them from binding properly to the active site of the protease enzyme. Perhaps they're pointed in the wrong direction, or perhaps there happens to be missing electrical interaction that's needed to keep the substrate in position.

Nonetheless, L-amino acids, on the other hand, seem to have the right configurational aspects in the active site and are hydrolyzed.

g In the mid-1800s, overhunting of Northern Elephant Seals reduced their population size to fewer than 40 individuals. However, the population has since rebounded to over 100,000 animals. The population went through a _________, which makes it more susceptible to ___________.

Answers

Answer:

In the mid-1800s, over-hunting of Northern Elephant Seals reduced their population size to fewer than 40 individuals. However, the population has since rebounded to over 100,000 animals. The population went through a _bottle neck event (genetic drift)_, which makes it more susceptible to _developing a genetic disease_.

Explanation:

Genetic drift is the random change that occurs in the allelic frequency of a population through generations. The magnitude of this change is inversely related to the size of the original population. These changes produced by genetic drift accumulate in time. Eventually, some alleles get lost, while some others might set. Genetic drift affects a population and reduces its size dramatically due to a disaster or pressure-bottleneck effect- or because of a population split -founder effect- . The bottleneck effect most likely affects smaller populations.  

In the exposed example, extensive hunting acted as a pressure that reduced the number of Northern elephant seals to fewer than 100. This population experienced one or many generations of small size since these animals were affected by hunting. As the survivors did not have the whole genetic pool of the original population, the population size might have recovered to a current population size of 100,000 individuals, but the genetic pool might have not. When the small population increases in size, it will have a genetically different composition from the original one. In these situations, there is a reduced genetic variability, with a possibility of developing a peculiar allelic component. If the survivors in the population carried or developed a mutation, probably this mutation passed from generation to generation. It will involve more individuals each time and increase the probability of developing a genetic disease.

(MC)Read the following passage and answer the questions that follow:Doctor Pascalby Emile ZolaIn the heat of the glowing July afternoon, the room, with blinds carefully closed, was full of a great calm. From the three windows, through the cracks of the old wooden shutters, came only a few scattered sunbeams which, in the midst of the obscurity, made a soft brightness that bathed surrounding objects in a diffused and tender light. It was cool here in comparison with the overpowering heat that was felt outside, under the fierce rays of the sun that blazed upon the front of the house.Standing before the press which faced the windows, Dr. Pascal was looking for a paper that he had come in search of. With doors wide open, this immense press of carved oak, adorned with strong and handsome mountings of metal, dating from the last century, displayed within its capacious depths an extraordinary collection of papers and manuscripts of all sorts, piled up in confusion and filling every shelf to overflowing. For more than thirty years the doctor had thrown into it every page he wrote, from brief notes to the complete texts of his great works on heredity. Thus it was that his searches here were not always easy. He rummaged patiently among the papers, and when he at last found the one he was looking for, he smiled.For an instant longer he remained near the bookcase, reading the note by a golden sunbeam that came to him from the middle window. He himself, in this dawnlike light, appeared, with his snow-white hair and beard, strong and vigorous; although he was near sixty, his color was so fresh, his features were so finely cut, his eyes were still so clear, and he had so youthful an air that one might have taken him, in his close-fitting, maroon velvet jacket, for a young man with powdered hair.Which word, if substituted for "capacious" in the second paragraph, would best retain the meaning of the passage?
