which statement provides the best argument against making major changes to the atmosphere to help protect Earth's resources
Answer:
The options are
A. There will be less soil and dust in the air as construction increases.
B. The atmosphere will improve as more people move to large cities.
C. Making major changes to the atmosphere can be a costly process.
D. It is more important to protect land and water resources than the atmosphere.
The answer is C. Making major changes to the atmosphere can be a costly process.
Explanation:
Making major changes to the atmosphere to the atmosphere to help protect Earth's resources is costly because no one knows the effects of what the changes will have when effected. Another angle is effecting the changes will be a very expensive one as the atmosphere is very large and will be difficult having it happen.
This however validates making major changes to the atmosphere can be a costly process as the right option.

A colorimeter is an instrument used for chemical analysis by comparing a liquid’s color with standard colors. In an experiment, a scientist used two colorimeters and noted the readings. The first colorimeter showed consistent readings that were five points lower than the actual reading. The second colorimeter provided readings that were the same as the actual reading. Which two statements are implications of these readings?
1). The first colorimeter is reliable but not valid.
2). The second colorimeter is valid and reliable.
3). Both the colorimeters are reliable and valid.
4). The readings of the first colorimeter can be used without repeating the experiment.
5). The readings of the second colorimeter aren’t reliable and can’t be used for the experiment.
Answer:
The correct answers are option A and B
Explanation:
The first colorimeter is reliable because the the reading it is showing is same for all the times the experiment is done. Though the result obtained is wrong but it is reliable.
The second colorimeter is valid and reliable because it is showing the correct results again and again. This is valid result as it is giving the result same as that of actual readings.

1) Sucessão ecológica é o nome dado a uma série de mudanças que ocorrem nas comunidades de um determinado ecossistema. Sobre a sucessão primária, marque a alternativa correta: A sucessão primária ocorre em uma área que já foi ocupada por uma comunidade anteriormente. A sucessão primária pode acontecer em áreas desmatadas, por exemplo. A sucessão primária ocorre em ambientes estéreis, onde nunca houve a ocupação por seres vivos. A sucessão primária é o último estágio da sucessão ecológica.
Answer:
A sucessão primária ocorre em ambientes estéreis, onde não havia vestígios de organismos vivos que a ocupassem antes. Esse ambiente pode ser um local vulcânico em que a lava derretida destruiu o meio ambiente ou foi causada por dunas. A comunidade inicial de organismos para habitar esses ambientes é conhecida como sucessores primários ou colonizadores primáriosrimários
Explanation:
Primary colonisers initiate primary succession as such they are important to the future of such environments. They are though breeds of organisms that make use of scarce resources to survive in harsh environments. Without their ability to survive, there will be little or no way other forms of succession can take place. Reasons, why they may not persist, maybe too much stress imposed on them by the environment and above all their inability to compete when other successors come on board.
A human baby is born with one X chromosome and one Y chromosome. What
must be true about this baby?
A. The baby is female
B. The baby is haploid
C. The baby is prokaryotic
D. The baby is male
Answer: d) the baby is male
Explanation: Ovules contain X chromosomes whereas sperms come in two types: one type contains x chromosome and the other contains Y chromosome.
When a sperm containing X chromosome fertilises with an ova, the zygote will have two X chromosomes. This zygote would develop into a female child. When a sperm containing Y chromosome fertilises with an ova, the zygote will have one X and one Y chromosome. This zygote would develop into a male child.

How is the cytokinesis of plant cell different from the animal cell during mitosis?
Answer:
a plant cell has a rigid cell wall however an animal cell does not. (more info below)
Explanation:
Because a plant cells are surrounded by the rigid cell wall, it cannot use microfilaments to go through cytokinesis. Instead, it builds a cell plate in the middle of the cell to represent the division. An animal cell does not have this rigid structure, so it forms a cleavage furrow by pinching the cell in the middle with microfilaments. This will successfully divide the cell into two.
hooe this helped!
Answer:
Cytokinesis is the final stage of cell division in eukaryotes as well as prokaryotes. In animal cells, the plasma membrane of the parent cell pinches inward along the cell's equator until two daughter cells form. In plant cells, a cell plate forms along the equator of the parent cell.

Answer:
They are: substrates, template, primer and enzymes. Four deoxyribonucleotide triphosphates (dNTP's) are required for DNA synthesis (note the only difference between deoxyribonucleotides and ribonucleotides is the absence of an OH group at position 2' on the ribose ring). These are dATP, dGTP, dTTP and dCTP.

A and B are biotic in nature, C, D, and E are abiotic in nature. In an open system, A produces D and E while B could not produce anything rather depend totally on the D and E produced by A. As the number of A increases, it favours the growth of B, the production of D and E also enhances the growth and development of B.
Answer:
A: Plants
B: Consumers
C: Sun
D: Oxygen
E: food
Explanation:
Abiotic factors refer to non-living things int he ecosystem, whereas the biotic factors are the living things in the environment.
A, in this case, is referring to the plants in the ecosystem, the producers. Plants produce D and E, that is, oxygen and food respectively. B are the consumers in the environment, the herbivores in particular that feed on the plants and rely on it as the only food source. C refers to the sun as the source of light energy for the plants.

Chemicals react with water and oxygen that enter water systems.

Nutrients in excessive amounts enter water systems, causing algal bloom.

A high concentration of toxic chemicals is present in the bodies of animals at the highest trophic levels.
arrowBoth
Answer:
The question is incomplete, the missing part i.e. the environmental change is:
(A) biomagnification
(B) acid rain
(C) eutrophication
The answers are:
1. Acid rain- Chemicals react with water and oxygen that enter water systems.
2. Eutrophication- Nutrients in excessive amounts enter water systems, causing algal bloom.
3. Biomagnification- A high concentration of toxic chemicals is present in the bodies of animals at the highest trophic levels
Explanation:
1. Acid rain is an environmental disorder in which rainfall becomes acidic due to pollution. The pollution is as a result of the release of gaseous chemicals e.g sulfur, nitrogen oxide, which are produced by industries, into the atmosphere. These chemicals then react with water in the atmosphere to form acidic solutions, which then falls back as rain. Hence, chemicals reacting with water and oxygen that enter water systems describes ACID RAIN.
2. Eutrophication is the pollution of water bodies with substances containing chemicals like nitrogen, phosphorus etc. The chemicals, which are in excess, serve as nutrients to algae, which uses them to grow excessively forming a bloom called ALGA BLOOM. Hence, nutrients in excessive amounts entering water systems, causing algal bloom describes EUTROPHICATION.
3. Biomagnification refers to the build up or accumulation of toxic chemical substances in the body systems of living organisms higher up in the food chain. Pollutants like pesticides, herbicides flow into water bodies and are absorbed by certain aquatic organisms. When these organisms are fed on by consumers, the harmful substances accumulates in their tissues until it reaches a maximum concentration. Hence, a high concentration of toxic chemicals present in the bodies of animals at the highest trophic levels describes BIOMAGNIFICATION.
Answer:
1. Acid rain- Chemicals react with water and oxygen that enter water systems.
2. Eutrophication- Nutrients in excessive amounts enter water systems, causing algal bloom.
3. Biomagnification- A high concentration of toxic chemicals is present in the bodies of anima
