Which selection from the article "Scientists study Persian Gulf reefs for coral survival clues" identifies the biggest threat to coral reefs?

Question 5 options:

Warming waters spark bleaching events. Along with the bleaching, the ocean is becoming more acidic.


The researchers demonstrated that this new organism was the most commonly found algae throughout the gulf's coral reefs. They say it probably adapted as a result of the gulf's harsh conditions.

Answers

Warm and acidic water leads to bleaching of coral reef and the new algae can survive due to mutation in its gene.

The biggest threat to coral reefs in the Persian gulf is the warming of waters due to climatic change as well as acidification of water. Algae present on coral reefs can't tolerate acidic water as well as warm water which leads to the death of algae and the coral looks white or colorless.

A new organism was the most commonly found algae throughout the gulf's coral reefs due to change in the genetic makeup due to harsh climatic conditions so we can conclude that warm and acidic water leads to bleaching of coral reef and the new algae can survive due to mutation in its gene.

_________________________ happen when extra base pairs are included in an existing DNA sequence.

_________________________ happen when base pairs in an existing DNA molecule get removed from it.

Fill in the blanks correctly

Answers

Answer:

Explanation:

A base pair is two chemical bases bonded to one another forming a "rung of the DNA ladder." The DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.

Which type of mutation reverses the direction of parts of a chromosome?

Deletion
Duplication
Inversion
Translocation

Answers

Answer:

Its "C"  Inversion

Explanation:

I took the test and got it correct

Type of mutation reverses the direction of parts of a chromosome is inversion. The correct answer is option C.

What is the basic structure of chromosome ?

The chromosomes are thread like structures present in the nucleus and the  these chromosomes carry the genetic information in them from one generation to another.

Inversion inverts the structure of chromsome and it basically turns the chromsomes inverted.

Inversion is the process where one arm of the chromosome gets detached from the basic structure and it gets attached in the inverted direction.

This  creates multiple copies of DNA turning it into genetic material and one of the X linked recessive disorders is haemophilia in which same type of mutation caused by the chromosome at the 8th position takes place.

Therefore, Mutation that reverses the directions of the part of the chromosome.

A student named Janine says that the measure of side b is 64 ft. Please state whether this is correct or incorrect. If this is incorrect, state the length of b. Explain your answer in complete sentences. Use vocabulary such as Pythagorean Theorem, side, hypotenuse, square root etc.

Answers

The measure of side b as 64 ft is incorrect. The accurate measure would be 8 ft.

According to the Pythagorean theorem, the square of the hypotenuse of a right-angle triangle is the sum of squares of the opposite and the adjacent sides. Mathematically:

[tex]hypotenuse^2 = opposite^2 + adjacent^2[/tex]

In this case, the hypotenuse = 10 ft, the opposite = 6 ft and the adjacent = b

Hence,

b^2 = 10^2 - 6^2

       = 100 - 36

          = 64

b = √64

     = 8 ft

Thus, the side b is 8 ft and not 64 ft.
