Answer:
B. They are very sensitive to environmental change
Explanation:
Certain organisms like plants, animals and microbes are used to monitor pollution status of the environment. These organisms are called indicator species or bioindicators. They are widely used for pollution monitoring due to their sensitivity to environmental changes i.e. in the presence of a pollutant, they undergo morphological or physiological changes.
A common example of indicator species is the proliferation of algal species in a water body known as ALGAL BLOOM. They tend to grow excessively in the presence of pollutants in form of nitrates and phosphates which they use as nutrient.

Explanation:
properties that virus have on life are virus are infectious agents with both living and non living characteristics.
the property that they lack is they don't grow, they lack hamoestasis, and they don't metabolize.
the viruses are alive when they enter inside the body and not alive when they are outside the body hence u can say both.

James was sick, went to the doctor, and was diagnosed with a bacterial throat infection. His infection was treated with antibiotics. In a few days, James felt much better, but some resistant bacteria survived and, overnight, James was sick again. This time, he had to take a much stronger antibiotic.
Answer:
See the answer below
Explanation:
The complete question reads: James was sick, went to the doctor, and was diagnosed with a bacterial throat infection. His infection was treated with antibiotics. In a few days, James felt much better, but some resistant bacteria survived and, overnight, James was sick again. This time, he had to take a much stronger antibiotic. The resistant bacterial cells illustrate what characteristic of life?
All living things respond to stimuli.
All living things maintain homeostasis.
All living things adapt to changes in their environment.
All living things contain genetic material and reproduce.
The correct answer would be that all living things adapt to changes in their environment.
Generally, all living organisms try to adapt to changing environments. Those that are able to successfully adapt survive in the environment and are able to produce offspring that are also able to survive in the same environment. Organisms that are not able to adapt to a changing environment end up dying from the population. This is an example of evolution by natural selection - the survival of the fittest.

Which action would most likely increase the amount of carbon in the environment? A. Choosing to burn coal to generate electricity B. Using energy-efficient appliances in place of older, traditional appliances C. Reusing shopping bags instead of using disposable plastic bags D. Recycling paper and plastic instead of throwing it in the trash
Answer:
Choosing to burn coal to generate electicity
Explanation:
Burning coals to generate electricity is most likely to increase the amount of carbon in the environment because it emits carbon dioxide, hence option A is correct.
Why does burning coals increase the amount of carbon?When coal burns its carbon is combined with oxygen to produce more amount of carbon dioxide, for generating electricity coal burns is producing a large amount of carbon.
If fuel burns its oxygen reacts with carbon in the air forming carbon dioxide or reacts with hydrogen to form water vapor.
Using energy-efficient appliances in place of older, traditional appliances, has less chance to produce excess amounts of carbon in the environment. Recycling things also reduces the amount of carbon in the environment.
Therefore, choosing to burn coal to generate electricity is the correct option.

Botany Professor. Dr. Noa Nkembe. is conducting research over how temperature effects the toxicity of Toxicodendron diversilobum (poison oak). He grows the plant in controlled environments that are kept at temperatures that vary by just 0.05 degrees Celsius. Which of the thermometers would be the BEST choice for him to use for this experiment? Justify your answer. Glass thermometer Temperature probe Temperature strip
Answer:
Glass Thermometer
Explanation:
Glass oral thermometers typically have markings every 0.1 °C or 0.2 °F. Basal temperature is stable enough to require accuracy of at least 0.05 °C or 0.1 °F, so special glass basal thermometers are distinct from glass oral thermometers.
Compare the inputs and outputs of humans and robots in terms of matter and energy.
Answer: In contrast to human stance control, robot stance control is at an early stage of evolution. The need for some form of stance control system has been recognized during the recent rapid development of humanoid robots (see Mahboobin et al., 2008). However, the design of most robot balance systems has not taken advantage of existing knowledge of human stance control systems. A possible reason for this is that engineers focused on the obviously important interaction that occurs at the interface between the robot’s feet and the ground

Answer:
edge enhancement
Explanation:
Edge Improvement is an image processing filter that enhances the edge contrast of an image or video in an effort to improve its sharpness. Edge enhancement does not enhance subtle details found in more uniform areas of the image, such as texture or grain appearing in flat or smooth areas of the image. The filter works by marking the sharp edge boundaries of the image, the edge between a subject and the contrasting color background, and increasing the image contrast in the area around the edge.Experimental Scenarios

Science
Directions: Read the given scenarios below. Identify each required component for
each scenario.
Scenario 1:
A student is studying how far room temperature water would squirt out of a plastic
milk carton when 4 mm holes are punched at different heights from the bottom of
the container
Describe which are the independent and dependent variables as well as indicates
the constants involved within the experiment and why those are the constants.
Independent Variable:
Dependent Variable:
Constants:
Answer:
Independent variable: height of holes
Dependent variable: distance of squirting water
Constant: size of holes punched into the milk carton
Explanation:
The independent variable is one whose value is often manipulated during the course of experiments and the effects produced by the manipulation is measured on the dependent variable.
The dependent variable is the actual variable that is being measured in the course of experiments. The value of the dependent variable is affected by changing the values of the independent variable.
Constants are variables whose values remain unchanged throughout the course of experiments.
Hence, in the illustration:
Independent variable: the height of holes on the milk carton
Dependent variable: distance of squirting water
Constant: the size of holes punched into the milk carton
why are white blood cells unable to transport gases
Answer:
The majority of oxygen in the body is transported by hemoglobin, which is found inside red blood cells.
Explanation:
Although oxygen dissolves in blood, only a small amount of oxygen is transported this way. Only 1.5 percent of oxygen in the blood is dissolved directly into the blood itself. Most oxygen, 98.5 percent, is bound to a protein called hemoglobin and carried to the tissues.

Do you have reason to suspect that they should become isolated on the same dilution plate
Answer:
Please see below
Explanation:
Since the bacteria Serratia marcescens kept on growing even with higher dilution levels, it can safely be concluded that no, E. coli and S. marcescens would not become isolated on the same plate. The inoculum used should roughly contain 300 cells in order for it to not grow in clumps, rather make separate colonies.
A sequence of base pairs that codes information for a specific trait is called a ________. A. Nucleotide B. Gene C. Chromosome D. Enzyme
Base pairs are nucleotides that are the structural unit of the genetic material. Bases code for the traits that are in the form of genes. Thus, option B is correct.
What are genes?Genes are the primary unit involved in heredity and are composed of nucleotides that make the DNA. They are involved in the production of proteins through the process of translation.
Genes are made of alleles that code the traits inherited from the parents through the method of reproduction. The dominant alleles are expressed whereas the recessive are masked and not visible in the phenotype.
The alleles are made of chromosomes and DNA that are in turn made of nucleotide sequences, sugar, and a phosphate group.
Therefore, the base pairs code for the traits called genes.
