________________________ happen when pairs of bonded bases in a double strand of DNA get replaced with different pairs.
_________________________ 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
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.
The ability to taste the chemical PTC is determined by a single gene in humans with the ability to taste given by the dominant allele T and the inability to taste by the recessive allele t. Suppose two heterozygous tasters (Tt) have a large family.
QUESTION A: Predict the proportion of their children who will be tasters and non-tasters. Use a Punnett square to illustrate how you make these predictions.
QUESTION B: What is the likelihood that their first child will be a taster?

Explanation:
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.
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.

Explanation:
True or False: Because the microbiome is important for fitness, many organisms have developed specific strategies for passing the microbiome on to progeny.
The statement 'because the microbiome is important for fitness, many organisms have developed specific strategies for passing the microbiome on to progeny' is TRUE. It is natural selection in action.
According to the evolutionary theory proposed by Darwin, natural selection is the mechanism by which species change (evolve) to adapt to particular environmental conditions.
In this case, the microbiome represents an evolutionary adaptive mechanism, thereby natural selection will tend to favor individuals that have a beneficial microbiome.
In consequence, individuals having a beneficial microbiome will have more chances to reproduce and survive (i.e., they have higher adaptive fitness), thereby they also have more chances to pass this adaptive trait to the next generation.

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.
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.

Predator/prey web relationship is found in all ecosystem. A rise in the snowy owl population would have what effect on the snow goose in that The snow goose population would rise due to lemming, and subsequently fox, populations declining.
Food webs often has predator/prey relationships. They show the direct relationships in ecosystems such as the predator-prey relationships. Predators includes big cats such as cheetahs and lions.

how do amphibians breathe on land and in water
Answer:
Most amphibians can breathe both through cutaneous respiration (through their skin) and buccal pumping - though some also retain gills as adults. Some aquatic salamanders (and all tadpoles) have gills and can breathe underwater thanks to them. The Mexican axolotl, for example, never loses its gills.
