Answer:
1.33 dandelions per square meters
Explanation:
The correct answer would be 1.33 dandelions per square meter of land.
Size of quadrat = 1.5 square meters
Average number of dandelions per quadrat = 2
Total study area = 4500 square meter
Population density = number of organisms per unit area
There were 2 dandelions per 1.5 square meters
How many would be per square meter?
= 2 x 1/1.5 = 1.3333 dandelion per square meters
To 2 decimal places = 1.33 per square meters

Match each environmental change with its description.
Chemicals react with water and oxygen that enter water systems.
arrowBoth
Nutrients in excessive amounts enter water systems, causing algal bloom.
arrowBoth
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

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 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.

Which do you think is better for the environment: paper or plastic
Answer:
I think it is plastic
Explanation:
even though it take 400 years for a paper bag to decompose, people use more plastic.
Answer:
Paper is better for environment
Explanation:
Paper is because it decomposes much more quickly than plastic, and because of that it is less likely to be a source of danger and will not pose a risk to wildlife. Paper is also more recyclable, while plastic can take between 400 and 1,000 years to decompose.

How does the anaphase stage differ in the two phases of meiosis? A. Anaphase I separates sister chromatids and anaphase II separates homologous chromosomes into daughter cells. B. Anaphase I has homologous chromosomes attached to spindle fibres and anaphase II involves separation of these homologous chromosomes. C. Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells.
Answer:
The answer is Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells.
Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces two haploid cells. Meiosis II is analogous to mitosis, so in total, meiosis results in four haploid cells. So, in meiosis, there are two anaphases - the anaphase I in meiosis I and the anaphase II in meiosis II.
In anaphase I, the sister chromatids separate from each other to the opposite sides of the cells. In meiosis I there are 46 chromosomes in duplicate, which are present as pairs of sister chromatids. In anaphase of meiosis II, since the cell is haploid, there are 23 chromosomes in duplicate, which are present as sister chromatids.

Which two atoms form a covalent bond?
A. A sodium and chlorine atom
B. Two oxygen atoms
C. Two sodium atoms
D. An iron and oxygen atom
in a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.

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.
