Explanation:
The two (2) pieces of evidence that support the Big Bang Theory are: 1. red shift of light and cosmic background radiation.
The Big Bang Theory can be defined as an explanation by astronomers to describe how the universe was formed or started. These group of astronomers posited and argued that the whole universe stretched from a single point and then expanded to the way or manner it is right now.
Basically, Georges Lemaître was the astronomer that stated the Big Bang Theory and some of the principles of the Big Bang Theory include;
The universe stretched from a single point.The universe continues to expand.According to the Big Bang Theory, cosmic background radiation is typically a radiation that permeates our universe (space). Also, a red shift of light is a phenomenon which describes how light changes as physical objects in space move across the universe.
In conclusion, the two (2) pieces of evidence that support the Big Bang Theory are:
1. Red shift of light.

Why do scientists believe that life first emerged from the ocean and onto land well after the ancestors of modern-day cyanobacteria populated the Earth?
The cyanobacteria produced radiant energy from the nitrogen and carbon it absorbed from the shallow sea floor. Organisms needed this light energy to see on land.
These bacteria used visible light energy to create chemical energy, expelling oxygen that was converted to ozone. The ozone blocked the Sun's harmful UV radiation from reaching the ground.
The ancient cyanobacteria converted the Sun's radiant energy to heat, warming the ocean waters. They eventually drove many organisms from the oceans and onto land.
These bacteria provided a much needed chemical energy source for organisms living at the shoreline. Without this food source, the first land-dwelling organisms would not have survived.

Cattle and buffalo share a similar fundamental niche, the entire set of conditions under which a population can survive and reproduce. A realized niche is the set of conditions actually used by a given population. Explain what the data suggest about the realized niches of the cattle and buffalo and their ability to coexist. How can this data be used as an example of the competitive exclusion principle? Use evidence to support your explanation.
Complete answer:
You will find the table that provides data about the two species in the attached files.
Answer:
Because in the table provided you can see that, even when both species can use the same resources, certain vegetable species are eaten only by buffalo and not by cattle, while some other plants are eaten by cattle and not by buffalo.
Explanation:
The realized niche refers to the restricted conditions in which a species can live and survive as a result of environmental physic characteristics and the interaction with other species.
The competitive exclusion principle establishes that two or more species that share the same niche requirements and are in biological competition for the same resources, won´t be able to coexist indefinitely in the same space if the other ecological factors are constant. When the superior competitor occupies entirely the inferior competitor´s fundamental niche, the superior species has advantages over the other species and monopolizes all the resources. At this point, the inferior species is displaced and must adapt to use other resources changing its behavior, or must migrate to another area where it can get access to its needs, or get extinct.
Resources partitioning refers to one dominant species monopolizing the resources, and the other inferior species use other resources -partially or completely-, migrate or get extinguished. A way in which species can divide resources is by living in different habitat areas. These species might eat the same food, and can roost in different places within the habitat. This resource partitioning and differentiation in the function of their physical location allows both species to coexist more effectively.
In the exposed example, cattle and buffalo share the same fundamental niche, meaning that both of them can consume the same vegetable species, although in some cases, cattle eat certain species that buffalo does not, and vice-versa. Probably it occurred resource partitioning between these species, reflected in the fact that buffalo feeds on some species, while cattle feed on some other species.

7. Which of the following processes DOES NOT produce new genetic combinations?
crossing over during meiosis
b. fertilization in sexually-reproducing organisms
c. independent assortment in gamete production
d. replication of DNA in mitosis
Replication of DNA in mitosis does not produce new genetic combinations. The correct option is d.
In mitosis, DNA replication does not result in novel genetic combinations. Somatic cells go through a process called mitosis, which produces two identical daughter cells with the same genetic makeup as the parent cell.
The DNA is properly duplicated during mitosis while keeping the same genetic sequence. Therefore, during this procedure, no new genetic combinations or variants are introduced.
The other processes, including crossing over during meiosis, fertilisation in sexually reproducing organisms, and independent assortment in gamete formation, all help to produce novel genetic combinations by recombining genetic material.
Thus, the correct option is d.

How is the nitrogen cycle important to humans?
O It produces free nitrogen that humans can breathe.
O It converts nítrogen into a form that humans can obtain by eating other organisms.
O it produces nitrogen compounds that humans can breathe.
OIt converts nitrogen into a form that humans can obtain by absorbing it through their skin.
Answer: C
Explanation: it produces nitrogen compounds that humans can breath . It is the only logical choice.
It converts nítrogen into a form that humans can obtain by eating other organisms.
What is nitrogen cycle?The conversion of nitrogen between its different life-supporting forms, including nitrates and ammonia, occurs naturally as part of the nitrogen cycle. The nitrogen cycle creates free nitrogen that people can breathe, which is one of the most significant ways it is vital to people.
Humans cannot survive without nitrogen, which is necessary for all life. Additionally, the nitrogen cycle changes nitrogen into a form that people can consume by eating other living things like plants and animals. This is significant because it enables people to obtain the essential nutrients from their diet.
The nitrogen cycle also creates nitrogen molecules for human inhalation. These substances are crucial for preserving a healthy environment and can lessen the impacts of air pollution.
Last but not least, the nitrogen cycle also changes nitrogen into a form that people can absorb via their skin. This can lower the chance of developing specific medical disorders by preserving a healthy balance of nitrogen in the body.

Describe the function of the following
organelles:
a. Nucleus-
b. Cell membrane-
c. Chloroplasts-
d. Cell Wall-
e. Cytoplasm-
Answer:
Explanation:
The nucleus is the part of the cell that controls all other functions of the cell and the organelles. It also contains DNA.
The cell membrane acts as a semipermeable barrier between the cell and the outside environment to facilitate active and passive diffusion, and to maintain the concentration of solutes inside the cytoplasm. It also has receptors on its outer surface to communicate with other cells.
Chloroplasts use energy from photons of light from the sun to undergo photosynthesis, which helps the cells create glucose, or in other words, make its own food (in plants).
The cell wall protects plant cells from antigens and, due to its boxy shape, also helps the plant have a more rigid structure so that plants can stand upright.
The cytoplasm of a cell is the fluid within the cell membrane through which organelles in the cell move around. It is also the location where glycolysis typically takes place. The cytoplasm is mostly water with salts dissolved into it.

7. Which represents
an indirect economic value of
biodiversity?
A. food
B. clothing
C. flood protection
The answer is C. Flood Protection. Biodiversity provides numerous economic benefits, and one of the most important is flood protection.
What is the role of biodiversity ?Biodiversity helps to reduce the risk of flooding by providing natural barriers such as trees and vegetation that can absorb and store water, helping to reduce the amount of water that flows into rivers and streams.
Biodiversity also helps to reduce erosion by stabilizing the soil, which can help to prevent flooding by reducing the amount of sediment that can be washed away.
Additionally, biodiversity can help to reduce the impact of floods by providing habitats for wildlife that can help to reduce the impact of flooding on human communities.
For example, certain species of birds can help to reduce the impact of flooding by eating the insects that can spread water-borne diseases.
Biodiversity also helps to reduce the impact of flooding by providing habitats for aquatic species that can help to reduce the amount of damage caused by floods. All of these benefits help to make biodiversity an important indirect economic value.

Describe the modern model of the atom. Your discussion should include: the three main types of particles that make up an atom; the charge and location of each particle; and explain what the overall charge of the atom is. *
Answer:
See the answer below
Explanation:
The modern model of the atom sees it as a small structure with a dense, positively charged core called nucleus. The nucleus houses most of the masses of the atom and consists of the proton and the neutron. The positively charged proton is primarily responsible for the positiveness of the nucleus. At some distance away from the nucleus is a light, negatively charged particle called the electron that revolves around the nucleus in an orbit-like fashion .
For a neutral atom, the number of the positively charged proton balances that of the negatively charged electron which circulate rounds the nucleus. Atoms in which these two particles do not balance each other are no longer described as being neutral.
