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

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.

What is nucleotide base pairing?

There are five types of nucleotide bases adenine, cytosine, guanine, thymidine, and uracil. These divide into two classes of nucleotides pyrimidine and purine nucleotide bases. Pyrimidines are uracil, thymine, and cytosine whereas adenine and guanine are purines.

DNA consists of adenine, cytosine, guanine, and thymidine. In RNA, adenine, cytosine, and guanine are present but thymine is replaced by uracil.

Pyrimidine always binds with the purines through hydrogen bonding. Adenine binds with thymine. Cytosine binds with guanine. But when adenine pairs with uracil in RNA.

Therefore, these four bases are basic units of DNA.

Answers

Answer:

The RNA interference (RNAi) mechanism

Explanation:

RNA interference (RNAi) is a biological process by which endogenous non-coding RNAs (ncRNAs) sequences target messenger RNAs in order to inhibit gene expression and translation. The regulatory ncRNAs bind by complementary base pairing to specific mRNAs and thus promote gene silencing by both posttranscriptional (mRNA degradation, block translation, etc) and by transcriptional (recruiting of histone/DNA modifying enzymes) pathways. The most common types of evolutionarily conserved ncRNAs found in plant and animal cells are 1-small interfering RNAs (siRNAs), 2-microRNAs (miRNAs), 3-piwi interacting RNAs (piRNAs, only present in animal cells) and 4-long noncoding RNAs (lncRNAs).

2. Lac O or operator is a sequence situated just downstream to the sequence of the promoter at which binding of the repressor protein is done and ceases RNA polymerase enzyme from binding.  

3. Lac Z refers to the gene that encodes for protein beta-galactosidase, which further results in the formation of glucose and galactose from lactose.  

4. For high expression in E.coli IPTG is required. It attaches with the lac repressor and discharges the tetrameric repressor from the lac operator in an allosteric fashion, thus, permitting gene transcription in the lac operon.  

5. AmpR is also known as the ampicillin-resistant gene, which is utilized as a selective marker for selection against ampicillin antibiotic.

If an experimenter wants to use the GFP method but needs to detect the presence or absence of several proteins at the same time, he can take advantage of mutational variants of GFP that emit what light?

Answers

Answer:

different colors

Explanation:

The green fluorescent protein (GFP) is a type of protein widely used in molecular biology laboratories because this protein can be used to detect the expression of proteins and to identify cellular structures. This protein displays green fluorescence when it is excited by blue light and, in the last years, many variants of the GFP protein have been developed. The altered GFP proteins react to distinct wavelengths of light, thereby emitting light to different colors. The mutants forms of the GFP protein are produced by genome engineering techniques that generate modifications capable of altering the folding of the normal GFP protein.

You and your friends go to the beach for vacation. You all walk down to the beach to go swimming. When you get there, you see the water is murky and green, and there are algae blooms floating on top.

Reference: Ref 6-3

If it is excess nutrients which are feeding the algae blooms and lowering the oxygen content in the water, that process is called:
A. nutrient cycling.
B. nitrification.
C. eutrophication.
D. hypoxia.

Answers

Answer:

eutrophication

Explanation:

Eutrophication refers to a situation in which the aquatic environment becomes excessively enriched with nutrients. This leads to algal blooms in aquatic habitats such as lakes. These nutrients come from Fertilisers used in farming, which find their way into water bodies through run-off thereby increasing nutrient levels.

Excess nutrients causes phytoplankton to grow and reproduce at an alarming rate resulting in algal blooms. This bloom disrupts the balance in the ecosystem leading to many problems.

The algae may end up using all the oxygen in the water, causing oxygen shortage for aquatic life. Some of the algae may die, their decay may lead to further oxygen depletion. As oxygen is depleted, aquatic organisms may also begin to die.

If a mother is affected by an X-linked dominant condition and the father is not, which children can inherit the condition?
only males
neither males nor females
both males and females
only females

Answers

Answer:

both males and females

Explanation:

The sex chromosomes in male and female humans are X and Y chromosomes. X-linked traits are those traits which are associated with the X- chromosome.

According to the question, the trait is passed on a X-linked dominant condition, which means that the possession or not of the condition is dependent on the presence of the dominant X-chromosome. The dominant X-chromosome will always express itself even when in an heterozygous state with a normal X-chromosome i.e Xx. Hence, only a individual recessive for the X-chromosome will be normal.

A mother that is affected by the X-dominant condition will either possess a; XX or Xx genotype while a father that is normal (not affected) will possess a (xY) genotype. Since the mother passes one of her X chromosomes to her sons and the other to her daughters, both male and female children will be affected by the condition.

N.B: If the mother is heterozygous for the affected X-chromosome (Xx), half of her sons and half of her daughters will inherit the condition but if the mother contains two dominant X-chromosomes (XX), all of her sons and daughters will inherit the condition.

osteogenesis imperfecta is an inherited genetic disease that mainly affects the bones.  

Explanation:

Osteogenesis imperfecta is an inherited genetic disease associated with alterations in collagen synthesis, which have been shown to increase the risk to suffer bone fractures. This genetic disorder is characterized by different health problems including, among others, fragile bones, reduced skeletal mass, skin hyperlaxity, malformations in the central nervous system, etc. Clinically, osteogenesis imperfecta must be managed by an interdisciplinary medical team, since patients may present a clinical picture ranging from mild to lethal. In the first place, it is imperative to provide health care to avoid fractures, exercises to maintain muscle mass, exercise to improve motor skills, skincare by specialized dermatologists, etc.

The disease 'osteogenesis imperfecta' is caused by the neonate inheriting it

from either of the parent because it's a genetic disorder. The health care

provider should teach the parent about how to prevent the effect of having

such disease such as bone fractures.

Osteogenesis imperfecta is a genetic disorder inherited by offspring from

their parent. The disease involves individuals having very  brittle bones which are easily broken. The nurse should teach the parent to adopt bone strengthening steps such as adequate calcium intake and physiotherapy.

B) The repressor will no longer bind to the inducer.
C) The lac operon will be expressed continuously.
D) The lac operon will function normally.

Answers

Answer:

D) The lac operon will function normally.

Explanation:

The promoter area can be described as the area that causes the transcription to initiate for a particular gene. Promoters may be near the genes from which they initiate transcription or they may display multiple scenes upstream. The lock operon works normally because the promoter area can still enable transcription on many base pairs. Detects repression promoter and works normally.so correct option is D) The lac operon will function normally.

If a researcher moved the repressor gene of lac I, along with its promoter; the lac operon will function normally. Option D is correct.

Promotor:

It is the genetic sequence that is recognized by the RNA polymerase to start the transcription.

Answers

The correct answer is A. An infection that migrates via the bloodstream

Explanation:

Osteomyelitis is a serious condition, in which an infection develops in bones. This causes symptoms such as pain, inflammation, and can lead to the spread of the infection to other tissues or bone necrosis if it is not treated. In terms of causes, this condition develops when the bone is exposed to bacteria or similar that causes the infection, this can occur during surgeries or fractures. However, the most common source of infection is via bloodstream this means the bacteria or germ is in the blood and it enters the bone through the bloodstream. Also, once the bacteria or germ is in the bone it causes the infection.
