what are 4 phrases describing osmosis
Answer
The phrases would be;
-A passive transport
-Movement of water molecules
-Through a semipermeable membrane
-From a higher concentration to a lower concentration
Explanation;Osmosis is the process by which water moves from its higher concentration to a region of its lower concentration through a semipermeable membrane. Osmosis is an example of passive transport, since it does not require energy like the case of active transport.For example, when a cell is put in a hypotonic solution, a solution with more solvent concentration, the cells absorbs water from the solution through osmosis and increases in size.Suppose that Louisa is cut by broken glass during a lab accident. Which is the proper place to dispose of the paper towels that are used to clean up the blood?
broken glass container
hazardous waste container
spilled chemicals container
classroom waste container
Answer: hazardous waste container

Too much logging in the Oyamel fir forests could lead to the eastern monarch butterfly going extinct because _______. a. the entire population of the species spends winter in Oyamel c. the winters are too cold in Oyamel b. the butterflies breed in the Oyamel fir trees d. the butterflies feed on the Oyamel fir tree
Answer: a. the entire population of the species spends winter in Oyamel.
Monarch butterfly cannot survive in extreme climatic conditions. These butterflies spend winter months in Oyamel fir forest of Mexico. Oyamel forest situated in mountain hills provides an ideal climate for their survival. Here, the temperature ranges from 0 to 15 degree Celsius. If the temperature is low, the monarch butterflies uses their fat reserves. The dense canopy of trees in Oyamel fir forest drives heat from the ground at night and protect these butterflies from rain, wind and snow. The supply of excess of water as in the case of water logging condition can make trees susceptible to diseases and pests. In winter majority of monarch butterfly concentrate over the same region of Oyamel fir forest. Such water logging conditions will make the forest unsuitable for survival and further may lead to extinction of these butterflies.
Answer:
A
Explanation:
A group of students has performed an experiment to study the ideal temperature for the maximum activity of biological enzymes. Enzymes are specific to their environment; in other words, they work best at a specific pH and specific temperature. Which graph represents optimum enzyme activity at approximately 37 degrees Celsius?
Please refer to figures below.
Answer;
The first graph represents such an enzyme.
Explanation;
This is because the enzyme demonstrates greatest activity at approximately 37 °C but then the activity starts to decrease due to the denaturing of the enzyme.
As the temperature increases, so does the rate of reaction. But very high temperatures denature enzymes. The graph shows the typical change in an enzyme's activity with increasing temperature. The enzyme activity gradually increases with temperature up to around 37 ºC, or body temperature. Then the activity decreases above 37 ºC, because above this temperature the enzymes will denatured.

Explain how independent assortment occurs in cells and explain its importance.
Answer: Independent Assortment is the second law of inheritance.
Traits are passed from parents to offspring independently of one another.
Independent assortment is random and occurs during Metaphase 1 of meiosis.
These are two possible alignments for the chromosomes.
Since the alignments are random and not assigned, genetic variation occurs.
Explanation: On Ed
Independent assortment occurs during meiosis when homologous chromosomes line up randomly, allowing for genetic variation. Recombination through crossover events further contributes to independent assortment. This ensures that alleles on a given chromosome are not always inherited together, promoting genetic diversity.
Explanation:Independent assortment occurs during meiosis when homologous chromosomes line up in random orientations during metaphase I. Each gamete can contain any combination of paternal and maternal chromosomes, resulting in genetic variation. Recombination through crossover events also contributes to independent assortment by exchanging genetic material on homologous chromosomes. This ensures that alleles on a given chromosome are not always inherited together, allowing for more genetic diversity.

Answer:
The MOST accurate way to determine the evolutionary relationship between two animals is through the examination of DNA.
Explanation:
The diversity of life forms on Earth originated from mutations selected by greater reproductive capacity over time. From the DNA of the original cell came the infinity of life forms with which we share the earth through the mechanisms of mutation and recombination.
Evolutionary history shows us how all living beings are more or less related to each other. Some percentages of similarity between the sequences of the human genome and other species are striking: we have 95% in common with chimpanzees, 89% with mice; 45% with fruit flies and up to 9% with Escherichia coli, the bacteria in our intestines. This similarity is an indication of the common origin of all living beings and enables the analysis of divergences from one species to another.

Which component of blood protects us from invading foreign material?
The components of blood that protect us from invading foreign materials are White Blood Cells, certain proteins in the plasma such as antibodies, antigens, and platelets.
Explanation:The component of blood that protects us from invading foreign material is primarily the White Blood Cells (WBCs), or leukocytes, as part of the immune response. WBCs identify and target invading bacteria, viruses, and other foreign organisms. Not only do they combat foreign invaders, but they also recycle waste components such as old Red Blood Cells.
In addition to WBCs, certain proteins in the plasma, such as antibodies and cytokines, defend the body against infection and other threats. For instance, when damage occurs to blood vessels resulting in bleeding, blood platelets and coagulation factors present in the plasma interact to seal the ruptured areas, preventing further blood loss and protecting the body.
Another important component, called antigens, triggers an immune response when foreign antigens appear in our blood. Proteins known as antibodies, produced by certain B lymphocytes called plasma cells, attach to these foreign antigens to neutralize them.

Scientists use observations and data to form and test
Scientists use observations and data to form and test hypotheses. They observe a phenomenon, form a hypothesis about why it occurs, and use data to test its validity through experiments, making observations and data the backbone of the scientific method.
Explanation:Scientists use observations and data to form and test hypotheses. These hypotheses are proposed explanations for specific phenomena that have been observed. A scientist makes an observation, forms a hypothesis about why that phenomenon occurs, and then uses data to test the validity of the hypothesis.
For example, a scientist may observe that certain plants grow better in certain types of soil. They might form a hypothesis that the nutrients in the soil are causing this difference. To test this hypothesis, they would conduct an experiment comparing plant growth in different types of soil, carefully recording and analyzing the data from this experiment.
In this way, observations and data form the backbone of the scientific method, which is a systematic and logical approach to discovering how things in the universe work.

An experiment in which only one variable is changed is a(an) __________ experiment.
A. randomized
B. natural
C. double blind
D. controlled
Answer;
D. controlled
An experiment in which only one variable is changed is a controlled experiment.
Explanation;
-A control experiment is an experiment where the researcher only changes one variable at a time in order to isolate the results.
In a controlled experiment, most conditions are constrained so that they do not change. One or two other conditions are then changed and measured by the experimenter. These are known as the independent variables.
For example; An experiment where all subjects involved in the experiment are treated exactly the same except for one deviation.
An experiment that is only one variable that has changed is a controlled variable experiment.
the independent/controlled variable
is a variable that can be changed according to the purpose of the experiment
Further explanation
The development of chemistry begins with experiments that consist of chemical stages/processes. This method is a form of the scientific method that is commonly used by scientists in carrying out experiments.
Several experiments, trials, and errors will be carried out to test the hypothesis until the expected results are in the predetermined problem at the outset.
Variables, which can be determined in 2:
1. independent variable, which is a variable that can be changed according to the purpose of the experiment
2. fixed variable, i.e. variable whose value is constant and observed to determine changes in independent variablesWe can control independent variables according to the results of the experiments to find conditions that have the most optimal results so that the goals of the problems that have been set will be achieved.
The continuous investigation is so that the control variables are not out of the problem boundary
So the right choice is a controlled variable
