Bear in mind the biological definition of a species and also the appearance and distribution of the named populations of Ensatina. Which populations could be considered a species separate from E.e. eschscholtzii?

Answers

Answer 1

Answer:

E.e. oregonesis

E.e. platensis

E.e. xanthoptica

E.e. croceater

E.e. eschscholtzii

E.e. klaubori

Explanation:

The species mentioned above are probably separate species from E.e. eschscholtzii. this separation occurred due to geographic isolation, where each group of E.e. eschscholtzii evolved creating new species. This type of speciation is called "ring species" and refers to an evolution that is capable of providing species with extremes of variation that are not intercrossed, due to geographic isolation.

A young woman, who was adopted at birth, comes into your office asking you to help her identify her birth father. She already knows that the blood type of her birth mother is A positive. She knows her birth father is one of three men who are willing to help in her search. Your first step is to do a blood test on the daughter. Your results show that she is type AB negative. You make some phone calls and have the three possible fathers come in to give a blood sample. Here are the results:
Man #1 – O negative
Man #2 – B negative
Man #3 – AB positive
From this information, can you conclude who the father is? Is there anyone you can exclude? What tests could you do further to confirm your analysis about who the father is?

Answers

Answer:

Man no.3

Explanation: Mother A positive and daughter AB negative means that the dad would be AB positive.

If Tom Harris had type AB blood and Mary had type O, could the type O child they brought home be their child? * No, the baby would have to have inherited a gene for O from both parents and Tom has only a gene for A or B. Yes, both parents had the recessive hidden gene for O blood in their genotype which they passed on to the baby. No; the baby would have to have Type AB blood that it inherited from the father since A and B are dominate to O. Yes; the baby inherited type O blood from the mother Mary Harris which is dominant to the genes for both A and B.

Answers

Explanation:

No, the baby would have to have inherited a gene for O from both parents and Tom has only a gene for A or B.

The study of blood is called hematology. The component of blood is RBC, WBC, platelets, and plasma.

The correct answer to the question is option B.

What is a blood group?A blood type is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells. These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system.

The genes A and B are dominant over O therefore the O blood group can not be seen in offspring.

Hence, the correct answer to the question is option B is Yes, both parents had the recessive hidden gene for O blood in their genotype which they passed on to the baby. No; the baby would have to have Type AB blood that it inherited from the father since A and B are dominant to O.

AZT works by interfering with HIV's production of offspring inside a host cell. It does so by interacting with a molecule called reverse transcriptase.

a. True
b.False

Answers

Answer:

a. True

Explanation:

AZT is an abbreviation for azidothymidine and it is the first effective drug against the human immunodeficiency virus (HIV). Thus, azidothymidine is considered to be the first anti-retroviral drug used for the prevention and treatment of the human immunodeficiency virus (HIV).

AZT works by interfering with HIV's production of offspring inside a host cell. It does so by interacting with a molecule called reverse transcriptase.

Basically, the shape and composition of the reverse transcriptase plays a significant role in the interaction. Therefore, this anti-retroviral drug known as AZT may not work effectively if the shape and composition of the reverse transcriptase changes.

Furthermore, the high mutation or replication rate of the human immunodeficiency virus (HIV) owing to its enormous genetic diversity has made it extremely difficult to develop an effective and accurate vaccine against the virus.

Hence, the human immunodeficiency virus (HIV) possesses a high error rate.

Bloom syndrome is an autosomal recessive disease that exhibits haploinsufficiency. A recent survey showed that people heterozygous for mutations at the BLM locus are at increased risk of colon cancer. Suppose you are a genetic counselor. A young woman is referred to you whose mother has Bloom syndrome; the young woman's father has no family history of Bloom syndrome. The young woman asks whether she is likely to experience any other health problems associated with her family history of Bloom syndrome. What advice would you give her?

Answers

Answer:

The correct answer is - she is heterozygous for a mutated BLM allele and will have an increased risk of colon cancer.

Explanation:

Autosomal recessive disease expresses itself in next-generation only if there is both alleles are recessive for the gene. In haploinsufficiency, the dominant allele fails to express itself in the phenotype due to insufficiency. So, if even one allele of the recessive gene present in the haploinsufficiency case, it will affect and express its trait.

She is heterozygous for a blood syndrome, as her mother had but her father has no disease, allele and will have an increased risk of colon cancer.

F. There is always just one ozone hole in the Earth's atmosphere.

Answers

Answer:

Ozone holes have more ozone than usual.

Correct Answer

Ozone holes allow ultraviolet light to reach the Earth's surface.

Ozone holes don't have any ozone in them.

Chlorofluorocarbons make an ozone hole larger.

Explanation:

Ozone has been the atmospheric layer that protects the earth. It allows the ultraviolet rays to enter the earth, and there is one ozone hole due to the Chlorofluorocarbons. Thus, options B, C, and F are correct.

What is an ozone hole?

An ozone layer is defined by the presence of the ozone gas that is present in the atmosphere of the earth. The ozone hole is the hole in the ozone layer that is due to the depletion of the ozone gas in the layer due to increased global warming and pollution.

The increased concentration of Chlorofluorocarbons (CFCs) generated from aerosols, air conditioners, and refrigerants have resulted in a hole in the ozone layer. This lead to increased exposure of the organism to the harmful UV radiations emitted from the sun.

Also, this has resulted in increased climatic changes because of the global warming and heating of the atmosphere due to the entrapment of the UV and Sun rays. This leads to various diseases including cancer and eye irritation.

Therefore, the ozone hole is due to increased Chlorofluorocarbons. options B, C, and F are correct.

Black mice and tan mice are native species that are observed in a particular region. Human habitation in the region caused an invasive mouse species to enter the region. These mice are brown and share the same food requirements as black mice. Tan mice have different food requirements. How will this change affect the food web in the region? A. The availability of food resources for black mice and brown mice will decrease. B. The population of tan mice will decrease. C. The black mice and tan mice will compete for food resources. D. The tan mice and brown mice will compete for food resources.

Answers

Answer:

A

Explanation:

The correct answer would be that the availability of food resources for black mice and brown mice will decrease.

Since the food requirements of the black mice are the same as that of the invasive brown mice, the available food supply that used to be only for the black mice would now be shared by the two strains of mice. Hence, the available food for the two groups of mice will naturally decrease.

There is no sufficient information to conclude that the population of tan mice will decrease, hence, option B is incorrect.

The black mice and tan mice have different food requirements going by the information available in the illustration, hence, both cannot compete for food resources. Option C is, therefore, incorrect. In the same vein, option D is incorrect because the tan mice have different food requirements from the brown mice.

The only correct option is A.
