When electrons are transferred to a neutral object from another, neutral object might then become negatively charged. moving electrons from either negative charges object to a neutral object to negatively charge it.
What is an electron example?The smallest elemental component of an atom, the electron has a negative charge. In a neutral atom, there are an adequate amounts of protons and electrons. One proton and one proton are all that the hydrogen atom has. In contrast hand, the uranium atom possesses 92 protons, which means 92 electrons.
What materials make up electrons?Quarks make up protons and neutrons, but not electrons. We believe that quarks and electrons represent fundamental particles that are not composed of lesser subatomic particles. Saying that everything is composed of particles is one thing.

1. You have set up a cell-free transcription system in a test tube. By mixing DNA, RNA polymerase, sigma factors, ribonucleotides and other essential substances you are able to make mRNAs identical to those made under a variety of conditions in the cells from which these components were isolated. What would happen if you were able to remove the sigma factor first added to the tube and replace it with another sigma factor
Answer:
Different messenger RNAs (mRNAs) would have been produced
Explanation:
Sigma factors are protein subunits that form bacterial RNA polymerases and they are responsible to initiate RNA synthesis. The number of sigma factors is variable between different bacterial species. For example, Escherichia coli contains seven sigma factors, while Bacillus subtilis has at least 17 sigma factors, which control the transcription of different genes. These factors determine the specificity of the RNA polymerase to the target gene promoter regions and then control transcription initiation.

B. A change in the DNA sequence of a gene
Explanation:
Why would you expect to find a great deal of
parenchyma tissue in the roots of plants such as the
carrot, beet, and radish?
Answer:
Parenchyma tissue makes and stores food. Because the roots of carrots, beets, and radishes store food for plant, one would expect to find large amounts of parenchyma tissue in these parts.

Due to its location, Hawaii does not have very many land birds. The Hawaiian honeycreepers are a favorite for many ornithologists. There are over 50 species of honeycreepers that can all be traced back to one ancestor. The level of diversity in an ecosystem can be determined by the frequency of speciation and extinction.
Describe speciation and identify two possible prezygotic barriers of the Hawaiian honeycreepers that contribute to speciation.
If the Hawaiian honeycreepers became extinct, explain how the newly available niches could lead to speciation.
Answer:
In speciation, organisms evolved with the passage of time.
Explanation:
Speciation is the evolutionary process in which populations of species evolve with the passage of time to become different species from the original one. Temporal isolation and gametic isolation are two possible prezygotic barriers of the Hawaiian honeycreepers that contribute to occur speciation. The newly available niches could lead to speciation of that organisms that tolerate the Hawaiian climatic conditions when the extinction of Hawaiian honeycreepers occurs. The new organisms used the available resources such as food and space etc and increase its population.

What type of organism really spread and diversified during the Cenozoic?
reptiles
fish
amphibians
mammals
Mammals really spread and diversified during the Cenozoic era. So, the correct option is D.
What was Cenozoic era?The Cenozoic Era is defined as the third of the major eras in Earth's history that began about 66 million years ago and extends to the present. This epoch was the interval of time during which the continents assumed their modern configurations and geographic positions during which the Earth's flora and fauna evolved towards the present.
The Cenozoic Era is called the "Age of the Mammals", while the typical landscapes of North America began to develop during the Cenozoic. Birds and mammals rose to prominence after the extinction of giant reptiles.
Thus, Mammals really spread and diversified during the Cenozoic era. So, the correct option is D.

Do the plants and animals on a farm make up an ecosystem? Why or why not?
Answer:
Yes they do
Explanation:
Animals and plants make up a ecosystem because the animals feed off the plants and the animals feed off of other animals.
Answer:
All living things in ecosystems are part of a food chain. A food chain is how energy is passed between things. farms are ecosystems. Farmers work with crops, animals, soils, and the weather to grow our food.
Explanation:
Which statement about how geologists study the ages of rock layers is true?
The law of superposition means that older rocks are on top.
Geologists can find the exact age of a rock by looking at its relative position.
The principle of original horizontality provides the basis for the law of superposition.
Relative age can be determined by using the concept of unconformity.
Answer: The principle of original horizontality provides the basis for the law of superposition.
Explanation:
The law of superposition in geology suggests that the rocks or sediments which are newly formed due to erosion and sedimentation of the original rocks lie above the old material. This law is supported by the principle of original horizontality according to which the newly formed sediments suspend horizontally in the layers of rocks and sediments under the effect of gravity. Thus an horizontal strata distinguishes the old and the new material.

What is one of the biomolecules for which nitrogen is needed (hint: they help build muscles)?
One of the biomolecules for which nitrogen is needed and that build muscles are the proteins, and the nitrogen is also found in the DNA and RNA that are present in the cells.
What is the significance of the nitrogen in the protein?Proteins play many important roles in the body, including building and repairing tissues, and nitrogen is a critical component of proteins, as it is incorporated into the molecule as a part of the amino acids. Without nitrogen, proteins would not be able to form and perform their many important functions so a diet that is rich in protein is important for athletes and bodybuilders to build and repair muscle tissue.
