Which statement BEST describes the effect of human urbanization on biodiversity in the Amazon
rainforest?
A
Human urbanization increases biodiversity because cleared land attracts more
species into an area
B
Human urbanization decreases biodiversity because habitats and resources are
lost to native species
С
Human urbanization increases biodiversity because of non-native species
introduced to the food web.
D
Human urbanization decreases biodiversity because limiting factors of the forest
ecosystem are reduced.
Human urbanization would generally decrease the biodiversity of any forest because habitats and resources are lost during the process of urbanization.
Urbanization refers to the process through which cities are created out of urban areas.Cities are created by removing vegetation and erecting infrastructures such as buildings, roads, bridges, etc. The removal of vegetation means that habitats of organisms would be lost as well as the biodiversity that constitutes the vegetation itself.Thus, urbanization would automatically lead to a loss of biodiversity in the Amazon forest.

What is an essential characteristic of members of a given species?
the ability to produce eggs or live offspring without sexual reproduction
the ability to reproduce with members of another species
the ability to reproduce with one another and have fertile offspring
the ability to reproduce with organisms outside of their local gene pool
Answer:
the ability to reproduce with one another and have fertile offspring.
Explanation:
An essential characteristic of the members of a given species is the ability to reproduce with one another and have fertile offspring. Thus, the correct option is C.
What are the characteristics of a species?A species is a group of organisms which are living in an area with similar characteristics which are capable of exchanging genes and chromosomes and produce new organism similar to itself. The species are important as it maintains the equilibrium in the ecosystem.
A species can be defined as the largest group of organisms with the two individuals of the appropriate sexes can produce a fertile offspring, typically through sexual reproduction. The species can also be defined on the basis of their karyotype, DNA sequence, morphology, behavior or ecological niche.
Therefore, the correct option is C.

In hummingbirds feather color is incompletely dominant. A rather large population of hummingbirds has 396 red-sided individuals (RR), 257 brown sided individuals (Re) and 557 tan-sided individuals orr). Calculate the following:_______.
a. What is the allele frequency of the Rallele (o)?
b. What is the allele frequency of the rallele (a)?
Migration season comes and 200 of the red-sided individuals leave the nosulation before mating occurs.
c. After migration season what is the new allele frequency of the Rallele (0)?
d. After migration season, what is the new allele frequency of the rallelelo?
e. Which mechanism of evolution (natural selection, genetic drift, or gene flow) caused the allele frequencies to change?
Answer:
a) Frequency of the R allele: [(396 x 2) + 257] / (396 x 2) + (257 x 2) + (557 x 2) = 1049 / 2420 = 0.433
b) Frequency of the r allele: [(557 x 2) + 257] / (396 x 2) + (257 x 2) + (557 x 2) = 1371 / 2420 = 0.567
c) Frequency of the R allele: [(196 x 2) + 257] / (196 x 2) + (257 x 2) + (557 x 2) = 649 / 2020 = 0.321
d) Frequency of the r allele: [(557 x 2) + 257] / (196 x 2) + (257 x 2) + (557 x 2) = 1371 / 2020 = 0.679
e) migration is gene flow
Explanation:
Gene flow (also referred to as gene migration) is the movement of genes that acts to change allele frequencies in local populations by transferring genetic material from one population to another. Gene flow may be caused either by the movement of organisms that reproduce in new populations (migration), or by the movement of gametes (for example, pollen dispersal in plants).

What are chromosomes?A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones.
Chromosomes allow DNA to be accurately copied during these cell divisions. So one more time. Chromosomes are found in the nuclei of our cells and allow DNA to be accurately copied during cell division.
Chromosomes are arranged in ordered haploid sets around the centre of the metaphase plate at mitosis in several grass species and hybrids.

a. withdrawing large quantities from streams, lakes, and aquifers.
b. increasing runoff by clearing vegetation from the land.
c. altering weather patterns by clearing vegetation.
d. increasing flooding by disturbing natural flood controls.
Answer:
Water Withdrawal: it has happened in some lakes in Minnesota
Explanation:
The water cycle is influenced by seasonal-climatic fluctuations and human activity. Water withdrawal is one of the human activities that most seriously affect the amount of water in lakes and aquifers by reducing water storage, thereby altering the flow in streams, lakes and wetlands. Concerning this situation, the state of Minnesota incorporated 1- the use of a US database (State Water Use Database, SWUD) with useful water use information on withdrawals and consumptive uses and 2- an index based on the sum of permitted water withdrawal from surface and groundwater. This index estimates the use of water as a percent of the surface water runoff to define and predict the vulnerability of lakes, using data from 54 stream gages recorded from 1988-2007. The catchment scores are scaled from 0 to 100 depending on the percent of runoff used.

What are the two most important driving forces of metamorphism?
A. High heat and pressure
B. Melting and cystallization
C. Deposition and lithification
D.Weathering and accumulation
E.Magma and lava
ne questions
Answer:
Heat and pressure
Explanation:
Metamorphic rocks are found deep underground
The two most important driving forces of metamorphism are high heat and pressure (option A).
These two factors play a significant role in transforming rocks into metamorphic rocks. When rocks are subjected to high temperatures and pressures, the minerals within them undergo changes in their composition, structure, and texture. This process leads to the formation of new minerals and the recrystallization of existing minerals, resulting in the development of distinct metamorphic textures and structures.
The course of transformation doesn't dissolve the stones, however rather changes them into denser, more conservative rocks. Rearrangements of mineral components or reactions with fluids that enter the rocks produce new minerals.

Whales, birds, snakes, and fish need oxygen to survive. Even though they share this trait, these animals are not related because they do NOT —
A. inherit genetic instructions passed down from the same parents.
B. lives in the same type of environment.
C. eat the same types of food.
D. need oxygen to survive in their environments.
Answer:
A. inherit genetic instructions passed down from the same parents.
These animals are not related because they do not inherit genetic instructions passed down from the same parents. The correct option is A.
What is inheritance?The transmission of traits and otherwise information through one generation of individuals or cells to the next is referred to as inheritance.
Inheritance can occur through one of two mechanisms: genetic inheritance or epigenetic inheritance.
Deoxyribonucleic acid is another name for DNA. It is the genetic structure that is in charge of storing information.
A nitrogen base, sugar, and phosphate backbone make up DNA. Inheritance occurs when genetic information is passed from a parent to a child, and thus from one generation to the next.
A gene pair's two alleles are inherited, one from each parent. Alleles interact with one another in various ways. These are referred to as inheritance patterns.
Thus, the correct option is A.
