11.Explain why the newly created bacteria are considered genetically modified
Answer: Genetically modified bacteria are used to produce large amounts of proteins for industrial use. Generally the bacteria are grown to a large volume before the gene encoding the protein is activated. The bacteria are then harvested and the desired protein purified from them.
Explanation:
If only one species is considered the 'fittest', why do we still have so many variation among species?
Answer:
Variation occurs in species with the genes resulting in the traits and physical characteristics that make it possible for them to be among the fittest for a number of reasons:
1. Mutation
2. Recombination and
3. Migration
Explanation:
Mutations: A mutation is a deviation from the norm in a DNA sequence. It can be stimulated by errors during the DNA replication process which happens as the cell is dividing, or by exposure to ionizing radiation, chemicals, or viral infection (whether artificial or natural).
It is noteworthy that naturally, without any human intervention, the possibility of a spontaneous mutation is very low.
Recombination: This refers to the creation of new fusion of genes in the offspring that did not occur in the parents by the processes of crossing-over and independent assortment. Independent assortment meaning that the allele the gamete received for one gene was not influenced by the allele received for another gene.
Migration: Variation by migration here refers to the introduction of new genes from into one population by another. This could happen when a new population arrives at an existing one or when an existing one migrates to another population.
We can say for example that, genes from Americans have “migrated” into the population of African origin in America given the continuous immigration of Africans into America.
So in both populations, there are very fit species, but when their genes are mixed during cross-reproduction, variation arises.

Use the words flexor and extensor to explain how muscles work in pairs.
By contracting, muscles pull on bones and allow the body to move. ... Each muscle in the pair works against the other to move bones at the joints of the body. The muscle that contracts to cause a joint to bend is called the flexor. The muscle that contracts to cause the joint to straighten is called the extensor

What is ecosystem?Ecosytem is defined as a community that is biological by nature and the organism in that community attract with each other as well as their physical environment. Ecosystem is consist of both biotic as well as abiotic factor. The living components of ecosystem comes in category of biotic factor and non living components of ecosystem comes in category of abiotic factor.
Biodiversity is all the different kinds of life living in a particular area like the varity of animals, plants, fungi and microorganisms like bacteria and virus that plays a major role in framing of natural world usually three levels of biodiversity are observed and these are genetic species, and ecosystem diversity.
Biodiversity is very important for the process that's support all life present on earth including human.
Therefore,Biome that receives a lot of rain, moderate temperatures, and a long growing season is grassland. Thus, option D is correct.

Surface mining for coal involves removing all the vegetation and rock above the coal being mined. Which two of Earth's subsystems are most immediately affected by surface mining? Select one: A. Biosphere and hydrosphere. B. Geosphere and biosphere. C. Hydrosphere and atmosphere. D. Atmosphere and geosphere.
Answer:
B. Geosphere and biosphere.
Explanation:
Earth as a planet can be subdivided into subsystems called "spheres". The spheres that make up the Earth are as follows; geosphere or lithosphere, hydrosphere, atmosphere, biosphere etc.
As related to this question:
- The GEOSPHERE refers to the solid part of the Earth, which involves rocks, minerals etc. of the Earth crust. It can be regarded to be the physical land.
- The BIOSPHERE refers to a collection of all the living organisms inhabiting the Earth. This includes plants, animals, microbes etc.
According to these question, surface mining for coal is an act that involves removing all the vegetation and rock above the coal being mined. This means that the physical land/rocks (geosphere) and vegetation of plants (biosphere) covering the coal beneath are affected. Hence, based on the explanation above, GEOSPHERE and BIOSPHERE are two of Earth's subsystems most immediately affected by surface mining.
In 1859, Charles Darwin proposed that differential survival and reduction of individuals would produce changes in species population over time. In other words, the environment acting on variation of individuals within a population would result in an adaptation (an evolutionary process that results in morphological, physiological or behavioral changes at the population level and that increases the probability of the members of that population to survive and their reproductive success). Using a specific example, explain how natural selection explains the theory of evolution. Also include in your explanation and within your example, what are the 4 factors needed for natural selection to act
Answer:
Reproduction, heredity, variation in fitness or organisms.
Explanation:
Evolution occurs in organisms due to natural selection process because natural resources are limited. Evolution is the change in the characteristics of a species over several generations. If evolution occurs in the organisms so these evoluted organisms can survive rate more than those organisms where no evolution occurs because the evoluted organisms can adopt successfully the features of environment. Reproduction, heredity, variation in fitness or organisms are the four factors needed for natural selection to act.

What enzyme opens up in the DNA into two single strands ?
Answer:
DNA helicase
Explanation:
The image of this question shows the replication of DNA into two identical copies. However, before this occurs, the double-stranded DNA needs to be unwound or separated so that each single strand can serve as a template for a new strand.
An enzyme called DNA helicase is responsible for the separation of the DNA molecule into single strands. After which, DNA polymerase begins to add nucleotides to each single strand of DNA.

Melinda and Bart are sitting beside each other in the third car of a roller coaster.
From whose reference point are Melinda and Bart moving away from the observer?
A. a person sitting in the first car of the roller coaster
B. a person standing on the ground behind the roller coaster
C. a person sitting in the last car of the roller coaster
D. a person standing on the ground in front of the roller coaster
Answer:
The answer option that you are searching for today is the option "B."
From the reference point of a person standing on the ground in front of the roller coaster, Melinda and Bart are moving away from the observer. Therefore, option (D) is correct.
What is the reference point?A reference point is a fixed location or object used to determine the position, speed, and direction of motion of an object or person in motion. It is used in physics and other sciences to describe the motion of objects.
This is because the roller coaster is moving forward along the track, and the third car, where Melinda and Bart are sitting, is behind the first and second cars. As the roller coaster moves forward, the distance between the third car and the person standing on the ground in front of the roller coaster increases, indicating that Melinda and Bart are moving away from that observer. Therefore, the correct option is D, "a person standing on the ground in front of the roller coaster."

Name any three specifications that reduce carbon dioxide expenditure and promote biodiversity in the neighborhood you chose.
Hello. You have not shown the neighborhoods to which the question relates, which makes it impossible for your question to be answered accurately. However, I will try to help you in the best possible way.
The best way to reduce spending on carbon dioxide and increase biodiversity in a neighborhood is to provide tree planting through urban afforestation. A well-wooded neighborhood, it has a lower concentration of carbon dioxide because the plants absorb this gas releasing oxygen in place. In addition, some animals such as birds would attract them, in addition to promoting fruit and shade for the neighborhood.
Answer:
The most ideal way to lessen spending on carbon dioxide and increment biodiversity in an area is to give tree establishing through metropolitan afforestation. A well-lush area, it has a lower centralization of carbon dioxide in light of the fact that the plants assimilate this gas delivering oxygen set up. Likewise, a few creatures, for example, birds would draw in them, as well as advancing products of the soil for the area.

Sand for beaches comes from rocks in the area that are weathered down, and
their sediment is deposited in the area beaches. The beaches are then eroded,
and the sediment is moved away from the beaches. If rocks stopped weathering,
how would the beach change?
Answer:
Beaches would shrink until they were no longer there because the sediment is pulled away from the shores by the tide and there would be no new rock sediment to replace the old rock sediment.
