population of squirrels live together in forest an event occurred that caused the population to diverge into two different species over a long period of time which of the following is most likely the event occurred

Answers

Answer 1

A natural disaster.

Explanation:

A natural disaster would most likely have occurred to have the population of squirrels completely diverge from each other in order for them to become two separate species.

If a tornado, flood, earthquake, or another type of a natural disaster were to happen, it may have caused drastic damage to the ecosystem and environment of the squirrels. This would most likely cause the squirrels to split up, or diverge from each other and go to separate places in search of a new home.

Over time, these squirrels will reproduce with their own group. Each new group of squirrels, as they are both in different environments now, will have different adaptations from each other. This will eventually make it so they will never be able to reproduce with each other again if they were to meet, as they are now completely different species of squirrel.

Describe the intermolecular interaction of the surface carboxylate groups of a micelle and the surrounding water.

Answers

Answer:

Hydrophilic portions are outside and hydrophobic regions are inside

Explanation:

A micelle is an assembly of amphiphilic molecules formed in a liquid solution, generally an aqueous solution. Micelles are formed due to the packing (aggregation-like) behavior in which single-tail lipids are organized in a bilayer. A typical micelle in aqueous solution forms a spheric assembly where carboxylate ions are organized in a mode that hydrophilic head regions enter in contact with the surrounding water, while hydrophobic (lipophilic) portions are disposed inside the micelle.

a. Autosomal dominant
b. Autosomal recessive
c. X-linked dominant
d. X-linked recessive
e. Mitochondrial

Answers

Answer:

e. Mitochondrial

Explanation:

This is a case of mitochondrial heredity so correct answer is e. Mitochondrial In this case, the mother transfers her mitochondria to her children. So the child is affected. The male does not pass this trait on to his children. We can see from the lineage that the mother has defective mitochondria so all their children will have defective mitochondria. One of his sons has mitochondrial, but is unable to pass it on to the next generation.

Butterflies can produce hundreds of offspring per cross. In a certain variety of butterflies, a maternally-imprintable gene is responsible for wing phenotype. Two possible alleles for this gene are w for normal wings and wc for crinkled wings. Which of the following pieces of information would be helpful in predicting the wing phenotype of a male offspring from a cross?

a. look at the father's phenotype
b. know the mother's genotype
c. look at the mother's phenotype
d. know the father's genotype

Answers

Answer: d. know the father's genotype

Explanation: Butterflies can produce hundreds of offspring per cross. In a certain variety of butterflies, a maternally-imprintable gene is responsible for wing phenotype.

The option that would be helpful in predicting the wing phenotype of a male offspring from such a cross would be to look at the father's phenotype.

Imprinted genes can simply be defined as genes that are expressed in parent-of-origin specific manner and result from a chemical modification of DNAs.  Such genes are differentially expressed depending on which of the two parents they are inherited from. Hence:

maternally-imprintable genes are only expressed when they are inherited from the father. paternally-imprintable genes are only expressed when inherited from the mother.

Phenotype refers to the physical appearance or expression of a gene. Therefore, if a gene is maternally imprintable, looking at the phenotype of the father would be helpful in predicting the phenotype of the male child in case a cross happens.

Applying the same principle to the butterfly, it will, therefore, be helpful to look at the father's phenotype in order to predict the wing phenotype of a male offspring from a cross.

The correct option is A.

The ion composition of perilymph is like that of interstitial fluid; high sodium and low potassium levels. If someone ruptured the vestibular membrane, the membrane between the vestibular duct (Scala vestibuli) and the cochlear duct (Scala media), what would be the effect of such a rupture on the concentration of potassium in the endolymph in the cochlear duct

Answers

Answer:

The concentration of potassium will decrease

Explanation:

The cochlear ducts are composed of two distict types of fluids: 1-perilymph, rich in sodium (140 mM) and low in potassium (5 mM), and 2- endolymph, rich in potassium (1 mM) and low in sodium (150 mM). The perilymph fluid has a similar composition to the rest of the extracellular fluids, while endolymph present a unique ion composition that is not found in other fluids of the body. It is believed that the cochlea can regulate potassium flow without using energy (i.e.,  without use ATP), since potassium enters into the cells through passive pathways, while this ion ion leaves the cells by an active mechanism.

Describe how protein functional groups can act as acid and base catalysts. How is it possible for a single amino acid side chain to function as both?

Answers

Answer:

By changing the transition state and pH of the medium

Explanation:

Enzymes are proteins that bind to their corresponding substrates at their active sites in order to form complexes that catalyze specific chemical reactions. A key feature of this process is the fact that both acid and base catalytic activities may be combined in the same reaction. The acceleration in the velocity of the enzymatic reaction due to the addition of acids and bases is known as acid–base catalysis, where the acid or base is not consumed during the reaction. For example, enzymes can partially transfer a proton to the medium, thus changing the transition state of the chemical reaction and also decreasing its pH.

What do enzymes do? Please answer real quick

Answers

Answer:

Catalyze biochemical reactions.

Explanation:

Hello,

In this case, it is widely known that enzymes are able to take substrates or reactants to their active sites, in order to catalyze a raft of biochemical reactions by which products that are not usually formed under typical conditions are formed, and then allow them to dissociate from the surface of the enzyme. Such combination formed by an enzyme and its substrates is called the enzyme–substrate complex which is further taken to the isolated product.

Answer:

prevents blood from clotting normally due to the body's inability to form fibrin proteins.

Explanation:

Haemophilia is a genetic disorder which could be inherited and it is characterized by constant bleeding and loss of blood when injuries occur. This is as a result of the inability of the body to form fibril proteins. The fibril proteins are responsible for the production of platelets . The platelets are responsible for the clotting of blood.

This validates haemophilia being a disorder which prevent blood from clotting normally due to the body's inability to form fibrin proteins.

Genes, Chromosomes, and DNA Quick Check
If one half of a DNA molecule has 8 thymine bases, what else is also true about the DNA molecule? ( point)
There will be 16 total bases.
There will be 32 total bases.
There will be 8 adenine bases.
There will be 8 cytosine bases.

Answers

Answer:

There will be 8 adenine bases.

Explanation:

There are total of 4 nitrogenous bases present in a DNA that includes Adenine, Guanine, Thymine, and Cytosine. These nitrogenous bases form complementary base pair in which, adenine form two hydrogen bonds with thymine and cytosine form three hydrogen bond with guanine.

So, if there are 8 thymine bases in a DNA (irrespective of half or full) then there will be 8 adenine bases, forming two hydrogen bond with each other.

Hence, the correct answer is "There will be 8 adenine bases."

What term is used to describe a retrograde flow of urine from the urinary bladder into the ureters that is the cause of recurrent urinary tract infections (UTIs)?

Answers

Answer:

Vesicoureteral reflux (VUR)

Explanation:

Answer:

The condition is known as Vesicoureteral reflux (VUR)

Explanation:

Vesicoureteral reflux (VUR) is a pathological condition caused by Urinary Tract Infections (UTIs) where urine flows back from the bladder into one or both ureters, and sometimes back into the kidneys. The condition is commonly seen in young children under 2 years of age, and infants.

Most children with primary VUR were born with an abnormal ureter, which is mainly seen as a defective valve between the kidneys and the ureters that does not close well, hence resulting in refluxes. Secondary VUR develops due to some pathological conditions affecting the urinary tract, like blockage of the urethra, causing reflux of urine. Defective bladder nerves can also lead to VUR.

What are the characteristics of prokaryotic cells?

The prokaryotic cells are the primitive karyons that are defined by the lack of the true nucleus and organelles. Unlike the eukaryotes, the organelles lack the membrane that covers them but has a tough cell wall.

The prokaryotes include archaea and bacteria which are unicellular and microscopic organisms that are simple and have their genetic material organized into nucleoids in the center of the cell. They have the ability to live in harsh conditions.

Correlation between Health education and HomeScience PLEASE HELP! From The Adventures of Tom Sawyer by Mark Twain There was a rustling of dresses, and the standing congregation sat down. The boy whose history this book relates did not enjoy the prayer, he only endured itif he even did that much. He was restive all through it; he kept tally of the details of the prayer, unconsciouslyfor he was not listening, but he knew the ground of old, and the clergyman's regular route over itand when a little trifle of new matter was interlarded, his ear detected it and his whole nature resented it; he considered additions unfair, and scoundrelly. In the midst of the prayer a fly had lit on the back of the pew in front of him and tortured his spirit by calmly rubbing its hands together, embracing its head with its arms, and polishing it so vigorously that it seemed to almost part company with the body, and the slender thread of a neck was exposed to view; scraping its wings with its hind legs and smoothing them to its body as if they had been coat-tails; going through its whole toilet as tranquilly as if it knew it was perfectly safe. As indeed it was; for as sorely as Tom's hands itched to grab for it they did not darehe believed his soul would be instantly destroyed if he did such a thing while the prayer was going on. But with the closing sentence his hand began to curve and steal forward; and the instant the "Amen" was out the fly was a prisoner of war. His aunt detected the act and made him let it go. The minister gave out his text and droned along monotonously through an argument that was so prosy that many a head by and by began to nodand yet it was an argument that dealt in limitless fire and brimstone and thinned the predestined elect down to a company so small as to be hardly worth the saving. Tom counted the pages of the sermon; after church he always knew how many pages there had been, but he seldom knew anything else about the discourse. However, this time he was really interested for a little while. The minister made a grand and moving picture of the assembling together of the world's hosts at the millennium when the lion and the lamb should lie down together and a little child should lead them. But the pathos, the lesson, the moral of the great spectacle were lost upon the boy; he only thought of the conspicuousness of the principal character before the on-looking nations; his face lit with the thought, and he said to himself that he wished he could be that child, if it was a tame lion. Read these lines from the excerpt again: In the midst of the prayer a fly had lit on the back of the pew in front of him and tortured his spirit by calmly rubbing its hands together, embracing its head with its arms, and polishing it so vigorously that it seemed to almost part company with the body, and the slender thread of a neck was exposed to view; scraping its wings with its hind legs and smoothing them to its body as if they had been coat-tails; going through its whole toilet as tranquilly as if it knew it was perfectly safe.
