Which of the following materials is a good electrical conductor?
rubber
ceramic
plastic
copper
Answer:
copper
Explanation:
Copper has the best electrical conductivity of any metal, except silver. A good electrical conductivity is the same as a small electrical resistance. An electric current will flow through all metals, however they still have some resistance, meaning the current needs to be pushed (by a battery) in order to keep flowing.
________________________ 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.
From the THREE LAWS OF MOTION, choose 1 law then state the law and give an example.
Answer: The first low of motion states that an object at rest remains at rest and an object in motion remains in motion unless acted on by an unbalanced force. This is also knows as the law of inertia. One example of this is a ball. A ball stays put unless you push in which case it keeps on moving. However, it stops because of the force known as friction.

Answer:
Newton's first law of motion states that an object at rest remains at rest and an object in motion remains in motion with the same velocity unless acted upon by what we call an unbalanced force
Explanation:
For example, my cup of coffee is resting on my kitchen table as I make this lesson. The force of gravity pulling down is balanced by the force of my kitchen table pushing up on my cup of coffee. Now, if I am to move my coffee, I must apply an external force to disrupt the balance. Thank goodness my muscles are strong enough to apply such a force so I can enjoy my cup of coffee. Ah, now that's good joe! Newton's first law of motion is also referred to as the law of inertia

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.

Variation in offspring is important in maintaining genetic diversity within a population . Which of the answer choices indicates a mechanism of introducing genetic variation in a population? Select all that apply.
A crossing over during meiosis B ) fertilization of an egg by a sperm
C) independent assortment during meiosis
D) mitosis producing two new daughter cells
E) binary fission resulting in two bacterial daughter cells
Answer:
A B and C
Explanation:
Crossing over breaks, exchanges and rejoins chromosomes at corresponding points so introduces genetic variation. Because of crossing over offspring has characters of both parents.
Also independent assortment means that during separation of the chromosomes in anaphase, any chromosome can pair up with another. So for example if we have one parent plant with yellow and wrinkled seeds and other one with green and round seeds, then the gene responsible for round seed can pair up with either of the genes responsible for yellow seeds or green seeds. Hence the characters of offspring differ from the parents, it can have yellow round seeds or yellow wrinkled seeds and so on.
Mitosis will only produce 2 daughter cells which are exactly like their parent cells and are also identical to each other. Binary fission is a form of Asexual reproduction so it does not involve shuffling of genes from 2 parents.
Because of fertilization of egg with a sperm the maternal genes and paternal genes mix together. So it also produces genetic variations.
Tundra has mostly mosses, lichens, and grasses. What abiotic factors prevent other vegetation from growing in this biome?

Tundra is located on the artic zone. Therefore, permanently frozen soil and low precipitation is the reason of hindered plant growth.
What is a biome?A biome is an ecological unit that depicts the occurrence of a biological community in response to the particular climate and the environment.
Biomes support variety of habitats across the different continents. Various biomes together constitute a biosphere.
A biome is identified on the basis of temperature and precipitation it receives annually. The presence or existence of organisms is dependent on these two factors.
Based on topography, biomes can be classified into terrestrial, fresh water and marine biomes.
Some of the well known examples of biomes include tundra region, taiga region, grasslands, desserts and forests.
There are also special types of biomes known as ecotones where the two biomes merge. Salt marshes are the example of ecotone.
Thus, biome is the life supporting unit in ecology.

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.

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.
