Explain why a gene pool cannot be made up of only one individual
Answer:
All the possible alleles for a gene with multiple alleles cannot be expressed by single individual
Explanation:
Gene pool refers to the sum total of all the alleles of all the genes which are present in a population. Human beings are diploid organisms. One individual can have only two possible alleles for a gene. A gene can have two or more than two alleles. Since all the possible alleles for a gene with multiple alleles cannot be expressed by single individual, a gene pool cannot be made of one individual.
Describe the differences in biodiversity between the tropical rainforest and the arctic tundra.
Answer:
Explanation:he differences between the forest and the tundra are the climates,animals and plants.The tundra's climate is very cold while the forest is warmer and the tundra receives little sunlight whereas the forest receive direct and constant sunlight.the animals living in the tundra includes the arctic fox,snowy owl,caribou,ermine and polar bear and some tropical forest animals are the howler monkeys,sloths,jaguars,parrots and toucans.there are only a few plants that grow in the tundra.Some of them are the arctic moss,arctic willow,bearberry and pasque flower.These are the differences between the tropical forest and the tundra.
The two most diverse biomes are the tropical rain forests and the tundra biome.
The following are the differences in biodiversity between the tropical rainforest and the arctic tundra:
• The arctic tundra is classified as the cold icy desert, while the tropical rainforest is the wet climate group.
• In the Arctic tundra, the plains do not support trees, however, one can witness some bushes here and there, while the tropical rainforests are lush green comprising all the major kinds of trees and vegetation.
• The prime difference in biodiversity in the tropical rainforests and the Arctic tundra is the warmer temperatures and more rainfall, which allows more species to survive. While the Arctic regions exhibit the least vegetation and life due to extreme weather conditions that are temperature below the freezing points.
• Some of the species found in the Arctic regions are arctic moss, polar bear, arctic fox, arctic willow, and arctic hare. While the tropical rainforests comprise tall trees and animals like anteaters, sloths, lemurs, and others.
Thus, there is a vast difference in the biodiversity of the tropical rain forests and the Arctic tundra.

other than the number of species, what factor has the greatest effect on species diversity in an area?
Answer:
Habitat loss or change.
Explanation:
If an ecosystem is destroyed, or altered, the organisms in that specific area may struggle to survive, or have to relocate to a suitable habitat. When this happens it may result in a butterfly effect where species die or migrate away. The Species diversity will then decrease in that ecosystem.
Loss of habitat or geographical isolation has the greatest effect on species diversity in an area.
How does loss of habitat affect the species diversity?Habitat loss or change has direct negative impact on species diversity.

Hope this helps;)
Answer:
The small polar molecule enters a cell with help from a membrane protein by a process known facilitated diffusion.
Explanation:
The facilitated diffusion also known as passive diffusion. It allows movement of molecules along the concentration gradient whereas the process of active diffusion involves energy as it is against the concentration gradient.
The facilitated diffusion involves carrier protein and channel protein. Thus small molecules can easily pass through channel proteins.
how can the central dogma help us understand the process by which dna is turned into protein? what are the two steps involved in the process of gene expression?
Answer:
Read Below
Explanation:
The central dogma is the process of creating a protein from DNA.
Steps:
DNA->Transcription->mRNA->Translation->Polypeptide
Gene expression is done through the central dogma steps. The two steps would be transcription and translation
Answer:
The central dogma states that DNA contains the genetic code needed to make proteins—a process known as gene expression. Transcription and translation are the two steps involved in gene expression. In transcription, the DNA code is turned into RNA. In translation, the RNA sequence provides instructions to the cellular machinery to manufacture polypeptides, which become proteins.
Explanation:
What is the result of a mutation during meiosis?
The result of mutation during meiosis is that the offspring of the organism will have a mutation.
Meiosis is a proces by which cells divide in order to produce four other cells, each with half the full complement of DNA. Meiosis aims to produce gametes (eggs and sperm cells). Errors may take place during meiosis giving way to gametes with an extra or missing chromosome.
During the process of meiosis, chromosomes are replicated once in S phase (just like mitosis) into sister chromatids, but the cell divides twice.
The meiotic mutations are associated with genetic recombination and depend on double-strand breaks that initiate crossing over.
In biology, a mutation is an alteration in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal DNA. Viral genomes contain either DNA or RNA. Mutations result from errors during DNA or viral replication, mitosis, or meiosis or other types of damage to DNA (such as pyrimidine dimers caused by exposure to ultraviolet radiation), which then may undergo error-prone repair cause an error during other forms of repair,or cause an error during replication .
Mutations may also result from insertion or deletion of segments of DNA due to mobile genetic elements.Meiotic mutations cause genetic recombinations and are dependent on the breaks which occur on the double strands.
Thus,the result of a mutation during meiosis is genetic recombination.

Evolution is a process by which species change over the years. Various views explaining how evolution takes place have been proposed by scientists across the decades. Though most of these theories have been discarded, those of two scientists have been supported by different segments of the scientific community.
Jean-Baptiste Lamarck proposed the theory of inheritance of acquired characteristics to explain the process of evolution. It suggests that an organism can change itself willfully and pass on the acquired characteristics to the next generation or its offspring. Individuals develop traits that are useful and discard others that are not according to a predefined plot. Lamarck combined these two thoughts in his theory and substantiated them by evidence. One piece of evidence cited by him was that of the giraffe’s long neck. He said that giraffes stretched their necks to reach leaves on branches of high trees, and this gradually lengthened their necks over time. This acquired trait of a long neck was inherited by their offspring, and thus all giraffes now have long necks.
If you were to debate Lamarck today about his theory, what core concept in biology would you rely on?
A) Organisms lacking favorable traits will become extinct.
B) Mutations do not result in beneficial genetic variation.
C) Traits cannot be chosen willfully, but are randomly inherited from our parents.
D) Environmental stresses cause organisms to change, regardless of their genetic make-up.
Answer:
C) traits cannot be chosen willfully, but are randomly inherited by our parents
Final answer:
To debate Lamarck, I'd argue that traits are inherited through genetic information and changes are due to random mutations and natural selection, not the inheritance of acquired traits. Current scientific consensus disproves Lamarck's ideas, which conflict with the random and non-purposeful nature of evolutionary change.
Explanation:
If I were to debate with Jean-Baptiste Lamarck today about his theory of evolution, the core concept in biology I would rely on is C) Traits cannot be chosen willfully, but are randomly inherited from our parents. Lamarck's idea that traits acquired during an organism's life can be passed on to its offspring has been largely discredited by modern genetics and the understanding of heredity mechanisms. Instead, traits are inherited through genetic information contained in the DNA, and changes in traits from generation to generation are often due to random mutations and the process of natural selection, not the inheritance of acquired characteristics.
Moreover, Lamarck's assertion that species evolve according to a predefined plot suggests a purposeful direction in evolution, which contradicts the random nature of mutations that drive evolution in the theory of natural selection. Current scientific consensus maintains that while the environment can affect how genes are expressed (epigenetics), the idea that physical changes acquired during an organism's lifetime can be directly inherited is incorrect. This foundational principle in evolutionary biology, demonstrated through extensive research and experimentation, would be the basis of my argument against Lamarck's hypothesis of the inheritance of acquired traits.

Answer:

Explanation:
Having a high biodiversity can help an ecosystem to survive a disturbance it doesn't decrease the chances of one happening.
High biodiversity increases the chances of an ecosystem surviving a disturbance and contributes to ecosystem stability.
Explanation:Answer:
Biodiversity refers to the variety of living organisms in an ecosystem, including different species, genetic diversity, and ecological diversity. It plays a crucial role in maintaining the stability of ecosystems. High biodiversity increases the chances that an ecosystem will be able to survive a disturbance, such as a natural disaster or human activities. This is because different species have different roles and functions, and a diverse ecosystem is more resilient and adaptable to changes.
For example, in a forest ecosystem, a diverse community of plants, animals, and microorganisms interact and depend on each other. If there is a disturbance, such as a forest fire, a diverse ecosystem can recover more quickly because different species have different strategies for survival and can fill in the vacant ecological niches left by the disturbance.
In contrast, low biodiversity makes an ecosystem more vulnerable to disturbances. If an ecosystem has low diversity and one species is severely affected by a disturbance, such as a disease outbreak, the entire ecosystem can be destabilized. This can lead to a chain reaction, affecting other species that depend on the affected species, and ultimately leading to a collapse of the ecosystem.

Which is an adaptation that helped plants survive on land
A) diploid forms
B) Photosynthesis
C)Development of backbones
D) production of seeds
Answer:
D
Explanation:
In water, an embryo can exist without desiccation hence remain viable until it is able to develop into another plant. On land, however, the embryo will be prone to desiccation and seeds are a plant’s adaption to survive life on land. The seeds have a pulp that provides the moist environment enclosing the embryo. In addition, seeds have a testa/seed coat that drastically lowers the rate of loss of water from the inside of the seed to the environment.
The production of seeds is the adaptation that allowed plants to exist on land. Therefore, the correct option is D.
The development of seeds enabled plants to reproduce and disperse their offspring without the need for water. The protection and nutrition provided by seeds to the growing embryo allows plants to settle and thrive in a wide variety of terrestrial habitats. This adaptation has helped plants to successfully colonize a variety of terrestrial ecosystems and has contributed significantly to the success and diversity of plant species on Earth.
Therefore, the correct option is D.

A. keep populations of plants under control.
O
B. store excess carbon underground.
O
c. build up the amount of carbon dioxide in the air.
DD. preserve organisms that are extinct.
Answer:
B. store excess carbon underground
Explanation:
The fossil fuels have been formed on the basis of organisms that have died, mostly producers. These organisms have carbon stored in them. As they died and got covered by sediments, the carbon has been stored in the lithosphere. Since more and more sediments have been covering the stored carbon, it has been isolated and stored into the lithosphere for tens or even hundreds of millions of years, thus contributing to lowering the amount of carbon in the atmosphere for quite some time, and removing it from its natural cycle.

When the solution concentration on the outside of the cell is greater than the solution concentrate on the inside of the cell what type of solution is the cell within
The solution would be hypertonic.
A hypertonic solution is one where the concentration of solutes is greater outside the cell than inside.
Answer:
Outside it is hypertonic, whereas inside it is hypotonic solution.
Explanation:
We can classify the solution into three types:
Hypertonic, hypotonic and isotonic.
If a cell is placed in a solution where the concentration of solutes is more outside than inside, then the cell is said to be hypotonic with respect to cell exterior.
If a cell is placed in a solution where the concentration of solutes is less outside than inside, then the cell is said to be hypertonic with respect to cell exterior.
If the solute concentration is same both inside and outside the cell then the cell is said to be isotonic with the exterior solution.
Water always moves from low solute concentration to higher solute concentration across the semipermeable membrane to bring it to equilibrium.
