Answer:  

Cane toads were introduced intentionally in Australia in 1935 to combat cane beetles in the sugar cane crop fields. These toads exhibit higher feeding capacity. These can feed not only cane beetles but other insects which affecting agricultural yields. They are poisonous in nature, they kill any insect after ingestion. Therefore, they are useful biological insecticide which provides crops resistance against insects.

Suppose the volume of milk in a glass is 230 cubic cm. If 1 gallon of milk equals 3.79 liters, there are how many glasses of mil
balu736 [363]
Volume of milk that a glass can hold = 230 cubic cm
It is already given that
1 gallon of milk = 3.79 liters
W already know
1 liter = 1000 cubic cm
Then
3.79 liters = 1000 * 3.79 cubic cm
                = 3790 cubic cm
Now
Number of glasses needed to contain 230 cm^3 of milk = 1
So
<span>Number of glasses needed to contain 3790 cm^3 of milk = 3790/230
</span>                                                                                           = 16.48
From the above deduction, we can conclude that 17 glasses of milk are required to hold 1 gallon of milk.

A plasmid _____________________________ . A. can confer antibiotic resistance to a bacterium. B. is a single-stranded circular D
hodyreva [135]

Answer:

The correct answer will be option A.

Explanation:

The bacteria organize its genetic material in the single circular chromosome suspended in the cytosol along with additional circular double-stranded DNA molecule called plasmid.

The plasmid is present as a separate structure in the cytoplasm which performs important functions during stressful conditions in the bacteria like providing antibiotic resistance to the bacteria, formation of filial factors during conjugation and many others.

The plasmid which confers resistant to the bacteria is known as the R-plasmid. The R-plasmid consists of r-determinants which confers antibiotic resistance to the bacteria and resistance transfer factor (RTF) which helps in plasmid transfer.

Thus, option A is the correct answer.

A woman, S.R., had a maternal grandfather with hemophilia A (OMIM 306700), an X-linked recessive condition that reduces blood cl
Sidana [21]

Answer:

Hemophilia is a x-linked recessive inherited bleeding  disorder. in this disease blood does not clot properly due to the decreased level of blood clotting factor VIII (8) or factor IX (9).

In x-linked recessive condition, the disease is transmitted from father (affected male) to his daughter and mother (affected female) to her son and skip of generation getting affected is also occurs.

  • there will be 50% chance of her (S.R.) each son to be affected with hemophilia.

Explanation:

Hemophilia is caused due to mutation of one gene which is responsible for the making of proteins of  blood coagulation factor viii or ix. the affected person bleeds continuously from any injury and that can cause serious issues.

here,

grandfather of s.r is affected (xₐy) and grandmother is normal (xx) will produce

                                                   ↓

 s.r's mother who is a carrier (xₐx) [as xₐy and xx will produce 100% carrier xₐx daughter]

                                                    ↓

s.r's mother is a carrier (xₐx) but her father is normal (xy) will produce,

                                                   ↓

s.r who has 50% chance of being carrier (xₐx) and 50% chance of being normal (xx) [as she is the only child] and she has a normal (xy) partner, they will give,

                                                     ↓

  1. if s.r is a carrier (xₐx) then one of her son will be affected (xₐy)   [as xₐx and xy =xₐy]
  2. if s.r is normal (xx) then her son will be normal (xy) [as xx and xy will give xy]

here,<u> 50% chance of her son to be affected with hemophilia</u> [as S.R of being affected is more considerable].
