The rock cycle describes the way that rock material cycles through Earth's crust. All
rocks start out as lava or magma that cools into igneous rock. An igneous rock must then
be weathered into sediments for the next stage of the cycle. Sediments are compressed
and cemented to become sedimentary rock. Metamorphic rock forms when rocks are
heated and squeezed deep in Earth's crust. New igneous rock forms when metamorphic
rock is heated so much that it melts into magma, which cools into igneous rock. All rocks
go through this cycle over and over again.

Answer:
The rock cycle describes the way that rock material cycles through Earth's crust.
All rocks start out as lava or magma that cools into igneous rock.
Explanation:
The Rock Cycle is a process in Earth's crust of creating and forming different types of rocks. Through this process, three primary rocks are formed: Igneous rock, Sediment rocks, and metamorphic rocks.
From the given statements, the statements which are not true about the rock cycle are:
First one, the rock cycle does not desrcibe the way rock material cycles through Earth's crust but it is a process which creates and transforms different types of rocks.
Second statement is also wrong, because only igneous rocks starts out as lava or magma.
Therefore, statement first and second are not true.
how does the gulf stream affect the air masses above ocean water
Answer:
Locally, particularly off the coast of North Carolina, the Gulf Stream can affect water temperatures, providing warmer ocean waters and balmy days, even in the height of fall and winter.
Explanation:
The Gulf Stream affects the air masses above ocean water by:
Providing the ocean with warmer waters even during cold seasonsThe Gulf Stream is known as the strong current which occurs along the coast of Florida where there are warmer temperatures in the cold seasons and cooler temperatures in the warm seasons.
As a result of this, the Gulf Stream affects the air masses which are above the ocen water by making sure that the weather is more pleasant no matter the season of the year and it has also extended to parts of Europe.

Other than shape, what characteristics are used to identify the various bacterial species?
Answer:
Explanation:
One major characteristic used to identify bacterial species is by Gram staining. This makes bacteria to be classified into two broad classes; Gram positive bacteria (appear purple after stain) and Gram negative bacteria (appear pink after stain).
Another characteristic used is the presence or absence of capsule.
Other characteristics include there motility (which can be due to the presence of flagella), bonding tendency (which can be individually or in pairs) and also pathogenic bacteria can be classified as intracellular or extracellular bacteria.
What are the atomic masses of
protons, neutrons, and electrons?
Answer:
Protons, neutrons, and electrons: Both protons and neutrons have a mass of 1 amu and are found in the nucleus. However, protons have a charge of +1, and neutrons are uncharged. Electrons have a mass of approximately 0 amu, orbit the nucleus, and have a charge of -1.
Explanation:
The nucleus contains protons, neutrons, and electrons, each of which has a mass of 1 amu. Neutrons are uncharged, while protons have a charge of 1.
Thus, Electrons circle the nucleus, having a mass of about 0 amu, and a charge of -1.
Atomic mass of a proton: A proton's atomic mass is about equal to 1.007276 atomic mass units (u), or 1.007276 amu.
Neutron: A neutron has a slightly larger atomic mass than a proton. About 1.008665 u or 1.008665 amu is what it is. Electron: Compared to a proton or neutron, an electron has a substantially lower mass. An electron has a mass of roughly 0.00054858 u or 0.00054858 amu.
Thus, The nucleus contains protons, neutrons, and electrons, each of which has a mass of 1 amu. Neutrons are uncharged, while protons have a charge of 1.

Answer:
Allison and Robert should request a No-Knock Warrant.
Explanation:
A search warrant is a legally binding document that must be acquired by law enforcement officers or investigators before they can open up, enter and search a building. There are various types of search warrants.
Standard search and seize warrants require that law enforcement officers have to identify themselves and allow the occupant a significant amount of time to react. They'd have to knock or ring the doorbell in this situation.
Because law enforcement agents began to see the continued destruction of evidence before they got in, it necessitated the design of another kind of search warrant - the No-Knock Warrant.
By comparison, Allison and Robert will enter the suspect's house violently without advance warning with a No-Knock Warrant, so that if there is any evidence that can be used against the suspect, they will confiscate and protect it to prevent it from being destroyed.
Other types of warrants are:
Warrant to Arrest Warrant for Bench Arrest Warrant for Child Custody etcCheers

In the natural selection simulation we set the fitness of rr individuals to 0. Why does the r allele persist in the population?
Answer:
In the clarification section elsewhere here, the definition of the concern is mentioned.
Explanation:
The notion of fitness seems to be the basic phenomenon of Fisher. Fitness is a dynamic term since it is the calculation by a person in his lifetime of the cumulative production of viable progeny. The fitness of an organism is zero even though no offspring is created. With a growing life span as well as the amount of order to promote innovation, flexibility increases. Members of an organization that are very well-adapted to that certain range of environmental factors have had a benefit in the mechanism of selective breeding over others who might not be as possibly the best adapted. The benefit falls throughout the form of genetic diversity and longevity. Those people who are much more able to easily find and use food supplies, for example, would live considerably longer and have more offspring than someone who is less reliable at seeking food. Inherited features that increase human fitness are then passed on to their descendants, thereby providing this very same value to the descendants. The disappearance of fewer adapted varieties seems to be the most drastic alternative. Unless the best-adapted variant doesn't adjust even though it is as when the optimum balanced local, so for the ideal characteristic, less drastic will delete both-new variant.Since less drastic selection has become too inadequate to aggressive edge mutations, the aggregation of missense mutations will happen and even the outcome would be a progressive deterioration of genomic integrity. If it maintains you prolonged enough, this should contribute to disappearance for certain species; nevertheless, the subsequent widespread presence of the deleterious mutations just seems like such a genome would then inevitably also contribute to backward mutation incidence. Extinction could result if the intense choice has become too high for the entire world, because if the world is saved in time.Assume that plant height is determined by a pair of alleles at each of two loci (A and a, B and b) that are additive in their effects. Further assume that each allele represented by an uppercase letter contributes 6 feet to height and that each allele represented by a lowercase letter contributes 2 foot to height. If a plant with genotype AaBB is crossed to a plant with genotype aaBb, what heights are expected in the progeny
Answer:
16 feet, 20 feet, and 12 feet
Explanation:
Uppercase allele = 6 feet
Lowercase allele = 2 feet
First, let us look at the outcome of the cross between AaBB and aaBb.
AaBB x aaBb
Progeny:
4 AaBB = 6+2+6+6 = 20 feet
4 aaBB = 2+2+6+6 = 16 feet
4 AaBb = 6+2+6+2 = 16 feet
4 aaBb = 2+2+6+2 = 12 feet
The heights expected in the progeny are 16 feet, 20 feet, and 12 feet.

The deletion of a single base in a gene would alter the structure of the gene’s protein more than the substitution of one base for another
Answer:
True
Explanation:
Mutation is any change that occurs to the nucleotide sequence of a gene. Mutations can be of different types including: deletion, insertion, substitution etc.
Deletion mutation refers to the removal of one or more base from the nucleotide sequence while substitution mutation refers to the replacement of one or more nucleotide bases.
DELETION of a single base in a gene would alter the structure of the gene’s protein more than the substitution of one base for another. This is because deletion mutation can cause the reading frame of the nucleotide sequence to change, leading to a SHORTER STRUCTURE of protein.

Unmyelinated axons do not exhibit action potentials.
Answer:
The correct statement is - option B.
Explanation:
Unmyelinated axons are the axon that lacks the covering of scwann cells that form the myelin sheath which helps in the transfer or transmit the signals faster and more effectively in neurons. It acts as the insulating layer.
In absence of the myelin sheath, the action potential found everywhere along the length of the axon which leads to slow propagation than in myelinated axons.
Thus, the correct answer is - option B.
The net amount of carbon in the atmosphere between 1750 and 2012 ___________.
Answer:
From 280 ppm to 393 ppm.
Explanation:
In 1750, the amount of carbondioxide in the atmosphere was 280 ppm which increases by 393 ppm in 2012. This is because of the pollution occurs due to industrialization and number of vehicles increased in the world. More carbondioxide gas is released due to the smoke produced from burning of fossil fuels in industries and vehicles. So we can say that pollution is the main reason for increasing carbondioxide concentration in the atmosphere.
Explain why habitats with high biodiversity tends to contain narrow ecological niches and white habitats?
Answer:
because they reduce interspecific competition
Explanation:
Narrower niches are known to be more specific and limited compared to broader niches, which are generally less specific and less limited. The species that live in broad niches are named generalists because they are able to withstand different conditions. A narrow niche is often correlated with reduced overlap and thus tends to reduce interspecific competition. For example, coral reefs consist of a wide variety of species (including anemones, sea sponges, sea fans, brain corals, etc) which have narrow niches, thus showing high biodiversity.
