Differentiate between the geology of the continents of the Paleozoic, Mesozoic, and Cenozoic eras.
Answer:
The Paleozoic involved the appearance of fish, and eventually of life moving onto land. The Mesozoic was dominated by dinosaurs. The Cenozoic started with the extinction of the dinosaurs, and included the development of birds and mammals. ... The Mesozoic Era ended with another extinction.
The Paleozoic involved the appearance of fish, and eventually of life moving onto land. The Mesozoic was dominated by dinosaurs. The Cenozoic started with the extinction of the dinosaurs and included the development of birds and mammals. The Mesozoic Era ended with another extinction.
What is the difference between Mesozoic and Cenozoic?
The Mesozoic ended with a major extinction at the close of the Cretaceous Period. All dinosaurs except birds disappeared in this extinction. Another mass extinction occurred near the end of the Triassic Period. The Cenozoic Era was a time in which communities became more modern in appearance.

In the Hardy-Weinberg equation shown below, p is the frequency of the
dominant allele, and gis the recessive allele.
p'+ 2pq + 9 = 1
What does p2 represent in the equation?
A. The frequency of the heterozygous dominant genotype
B. The frequency of the homozygous dominant genotype
C. The frequency of the homozygous recessive genotype
D. The frequency of the heterozygous recessive genotype
In the Hardy-Weinberg equation shown below, p is the frequency of the
dominant allele, and is the recessive allele. p² in the equation represents the frequency of the homozygous dominant genotype.
Dominant allele: What is it?Usually, a dominant allele codes for a protein that functions. Because only one copy of the allele is required to produce enough enzyme to fully provide a cell with a specific product, the allele is dominant.
Describe genotype.An organism's phenotype, or observable traits, are derived from its genotype, or the chemical makeup of its DNA. All the nucleic acids in a DNA molecule that code for a specific trait are collectively known as a genotype.

2.They are allowed to function for an additional two hours per day during summers.
3.They are not allowed to employ children below the age of 18 as laborers.
4.Factories that emit higher amounts of pollution will be subject to penalties.
Answer:
1.Factories are entitled to tax credits if they adhere to pollution control levels stipulated by the concerned administrative body.
4.Factories that emit higher amounts of pollution will be subject to penalties.
Explanation:
Environmental policy is a term that refers to the guidelines established by governments or companies in order to preserve the environment in relation to the impacts that industrial activities can cause.
The two sentences above represent a specific environmental policy, because both refer to the reduction of pollution caused by companies during their activities. In addition, the phrases above show the punishments and reimbursements that compliance and non-compliance with this policy will bring to the company.
Pistol shrimps and gobies depend on each other for their shelter and protection,and they have a beneficial relationship with each other. What's this symbiotic relation called?
The given question is incomplete as it does not have the options which are:
A. commensalism
B. mutualism
C. parasitism
D. predator-prey
Answer:
B. mutualism
Explanation:
The species in the ecosystem interact with each other in many ways and one such type of interaction in which both the species are equally benefitted is known as the mutualism.
When one species provides benefit to second species whereas the second species provides benefit to the first species in a way that the evolution has transformed the relationship into an inseparable or highly dependent relationship.
In the given question, the shrimp provide a safe habitat to the goby fish whereas goby fish protect the shrimps from the predators. Since both the species are benefitting each other therefore the species form a symbiotic relationship.
Thus, Option-B is the correct answer.
Answer:
B: mutualism

Put the steps of transcription in order
The complementary RNA nucleotides are added.
RNA polymerase binds to the promoter.
DNA strands are unwound and separated
Answer:
1. RNA polymerase binds to the promoter.
2. DNA strands are unwound and separated
3. The complementary RNA nucleotides are added.
Take a look at the attached picture. First, the RNA polymerase must bind to the promoter region to initiate the whole process. DNA must be unwound by DNA helicase, then it will make the RNA transcript, which consists of adding the complementary RNA nucleotides to the DNA strand. Then the transcript leaves the nucleus and begins translation.
DNA strands are unwound and separated, RNA polymerase binds to the promoter, and the complementary RNA nucleotides are added. These are the steps of transcription in order.
What is transcription?Transcription is the process by which RNA molecules are synthesized from DNA templates. The first step in transcription is the unwinding and separation of the DNA double helix by an enzyme called RNA polymerase.
The enzyme binds to the DNA template strand separating the two strands and DNA template strand is further used for RNA synthesis, while the other strand is the non-template or coding strand. RNA polymerase then binds to the promoter region of the DNA template strand which is located at the start site of transcription.
After the binding, a complementary RNA starts synthesizing using the DNA template strand by adding complementary RNA nucleotides. As the RNA polymerase moves along the DNA template strand, RNA molecule starts growing which is complementary to the DNA template strand. This step is followed by elongation and termination of growing RNA molecule.
Therefore, transcription steps include DNA strands are unwound and separated, RNA polymerase binds to the promoter, and the complementary RNA nucleotides are added.

Summarize the flow of carbon, oxygen ,water, nitrogen, and phosphorus through an ecosystem. ( Minimum of three paragraphs please)
Answer:
Water is the basis of all living processes. More than half of the human body is made up of water, while human cells are more than 70 percent water. Thus, most land animals need a supply of fresh water to survive. However, when examining the stores of water on earth, 97.5 percent of it is non-potable salt water. Of the remaining water, 99 percent is locked underground as water or as ice. Thus, less than 1 percent of fresh water is easily accessible from lakes and rivers. Many living things, such as plants, animals, and fungi, are dependent on the small amount of fresh surface water supply, a lack of which can have massive effects on ecosystem dynamics. Humans, of course, have developed technologies to increase water availability, such as digging wells to harvest groundwater, storing rainwater, and using desalination to obtain drinkable water from the ocean. Although this pursuit of drinkable water has been ongoing throughout human history, the supply of fresh water is still a major issue in modern times.
Carbon, the second most abundant element in living organisms, is present in all organic molecules. Its role in the structure of macromolecules is of primary importance to living organisms. Carbon compounds contain especially- high forms of energy, which humans use as fuel. Since the 1800s (the beginning of the Industrial Revolution), the number of countries using massive amounts of fossil fuels increased, which raised the levels of carbon dioxide in the atmosphere. This increase in carbon dioxide has been associated with climate change and other disturbances of the earth’s ecosystems. It is a major environmental concern worldwide.
The carbon cycle is most easily studied as two interconnected sub-cycles: one dealing with rapid carbon exchange among living organisms and the other dealing with the long-term cycling of carbon through geologic processes.
Getting nitrogen into the living world is difficult. Plants and phytoplankton are not equipped to incorporate nitrogen from the atmosphere (which exists as tightly-bonded, triple-covalent N2), even though this molecule comprises approximately 78 percent of the atmosphere. Nitrogen enters the living world via free-living and symbiotic bacteria, which incorporate nitrogen into their macromolecules through nitrogen fixation (conversion of N2). Cyanobacteria live in most aquatic ecosystems where sunlight is present; they play a key role in nitrogen fixation. Cyanobacteria are able to use inorganic sources of nitrogen to “fix” nitrogen. Rhizobium bacteria live symbiotically in the root nodules of legumes (such as peas, beans, and peanuts), providing them with the organic nitrogen they need. Free-living bacteria, such as Azotobacter, are also important nitrogen fixers.
Phosphorus is an essential nutrient for living processes. It is a major component of nucleic acid, both DNA and RNA; of phospholipids, the major component of cell membranes; and, as calcium phosphate, makes up the supportive components of our bones. Phosphorus is often the limiting nutrient (necessary for growth) in aquatic ecosystems.
Phosphorus occurs in nature as the phosphate ion (PO43−). In addition to phosphate runoff as a result of human activity, natural surface runoff occurs when it is leached from phosphate-containing rock by weathering, thus sending phosphates into rivers, lakes, and the ocean. This rock has its origins in the ocean. Phosphate-containing ocean sediments form primarily from the bodies of ocean organisms and from their excretions. However, in remote regions, volcanic ash, aerosols, and mineral dust may also be significant phosphate sources. This sediment then is moved to land over geologic time by the uplifting of areas of the earth’s surface.

Which would most likely lead to reduced bird populations?
O A. Lack of land development
OB. Overplanting an area
O C. Introduction of non-native species
O D. Increased insect populations
Answer:
Introduction of non-native species
Explanation:
That would most likely lead to reduced bird populations is O C. Introduction of non-native species.Non-native predators may also prey on native birds and their eggs, leading to population declines.
What are non-native species?Non-native species, also known as alien, exotic, or introduced species, are organisms that have been introduced into a geographic area where they did not occur naturally, either intentionally or unintentionally, by humans.
C. Introduction of non-native species is most likely to lead to reduced bird populations.
Non-native species may compete with native species for resources such as food, nesting sites, and breeding territories, and may also introduce new diseases and parasites that the native species may not be able to cope with.
Non-native predators may also prey on native birds and their eggs, leading to population declines.

Explanation:
A farmer crossed a yellow maize plant (Yy) with another yellow maize plant (YY). He planted 200 seeds from this cross. How many of the plants would be yellow?
Answer: 200 seeds will be yellow.
Explanation: In this crossing, one parent will produce half of its gametes carrying allele Y and the other half carrying allele y. The other parent will have gametes with allele Y. After fecundation, the offspring could phenotype YY or phenotype Yy.
In genetics, Y is related to the dominant allele and y to the recessive one. In this case, having the Y dominant allele determine the color yellow. Therefore, as all of the offspring has the dominant allele Y for yellow, all of the seeds will be yellow, i.e., 200 seeds will be yellow.

The correct answer is A. How much energy does it take a bee to fly for 10 seconds?
Explanation:
When you make an observation you use a concise statement to describe a natural phenomenon you closely observed or measured. In the case presented the observations focus on the movement and size of the bee's wings.
According to this, an adequate question based on these observations need to focus on the movement and size of the bee's wings or the general mechanism they use to fly, thus, the best option, in this case, is "How much energy does it take a bee to fly for 10 seconds?" because this derives from the observations and focuses on the same phenomenon. Also, the fact bees have small wings and move them fast suggests it requires a lot of energy for bees to fly, which is exactly the key point in the question.

A. One of the late symptoms of MN is excessive edema, or build up of fluid within the interstitial space of tissue. Explain how loss of circulating blood protein (hypoalbuminemia) would cause edema with respect to hydrostatic and colloid osmotic pressure within capillary beds throughout the body.
Answer:
Albumin is a protein that attracts water in the compartment where it is found, that is why when circulating within the blood vessels the blood volume is maintained by this protein, so that the liquid or fluid that makes up the blood volume is retained within the capillaries due to hydrostatic forces and because the albumin protein is hydrophilic.
The albumin is decreasing, that is, in deficit or hypoalbulinemia, less water reaches the blood compartment, therefore the blood pressure or pressure will drop, the blood volume will decrease but not due to loss of it as in hemorrhages, but due to diffusion to other compartments. VASCULAR through the processes of OSMOSIS, in simple words, when this protein descends, water filters from the blood vessels to extravascular compartments, this phenomenon clinically manifests itself as EDEMA.
Explanation:
Hypoalbulinemia also occurs in severe nutritional disorders where ovalbumine is not consumed through the egg, since the person's diet is severely lacking, generating massive edema in the abdominal area or abdominal distension.
The effect that the plasma liquid has in spreading to extravascular spaces is called OSMOSIS, which draws water from the external environment by the oncotic pressure generated by other proteins.
The oncotic pressure is the pressure that is generated when the water diffuses from one compartment to another by attraction of a protein, it happens both with albumin and with other proteins of the organism that are characterized by being hydrophilic or attracting water.
Hypoalbulinemia destroys severe cardiac symptoms due to the high demand that an increase in edema and difficulty of venous return entail along with the fall in blood pressure.

In which type of cells would you find a permanent (Sap)vacuole: a plant or a animal cell
Answer:
The answer is plant cells they would be the type of cells you would find a permanent. an animal cell would not have that.
Explanation:
The reason plant is the answer is because plant cells contain a cell wall made of cellulose to strengthen the cell. They also have a permanent vacuole which is filled with cell sap to help keep the cell turgid.
The reason why animal cells don't have a permanent is because Animal cells may have more than one vacuole, and they are smaller than a plant cell's. Vacuoles are used to store materials in the cell that may be used by the cell or wastes that must be moved out of the cell.
