Ozone definitely protects us from various harmful radiations and prevent the direct entry of UV rays falling on Earth. There is a case in which if ozone is present at the ground level it is considered as a pollutant. the correct answer is option C.
What is the hole associated with the ozone layer ?It is the black hole that is continuously rising and getting bigger in size though the more study about it is still unsolved.
Ozone high in Earth's atmosphere protects from the sun's dangerous radiation. But on the ground level, ozone is definitely an air pollutant that spoils people and plants. Ground-level ozone formed when nitrogen oxides along with the volatile organic compounds reacts to each other in sunlight and more hot temperatures.
Ozone at ground scale is a harmful air pollutant because of the effects on people and the related environment and it is main ingredient in “smog."

A classmate has asked you to help them determine the concentration of DNA in their solution. Their A260 reading was 1.69. What was the concentration of their DNA
Answer:
Acid , phenol or protein
Explanation:
The ratio of absorbance at 260 and 280nm is what is usually used to assess the purity which a DNA or RNA posses. A ratio of 1.8 is generally accepted as being pure for a DNA sample and a ratio of 2.0 is generally accepted also as being pure for RNA. when the ratio is significantly lower in each case, it indicates that there is presence of protein, phenol or other contaminants.
Do neritic nones have sudden changes
Answer:
They face pounding waves as well as sudden changes in water levels and temperature that occur with high and low tides. Why is the neritic zone particularly in living things? It is rich in organisms because sunlight passes through its shallow water enabling photosynthesis to occur.

A student wants to know what effect temperature will have on the germination rate of radish seeds. To test this, she obtains 3 petri dishes and 60 radish seeds. She places 20 seeds in the first petri dish and stores it at room temperature. She places another 20 seeds in the second dish and places it in the freezer. She places 20 seeds in the third petri dish and places the dish in an incubator. Over the next two weeks, she waters the dishes daily and records the number of seeds germinate. At the end of the experiment she calculates the germination rate for the seeds at each temperature.
Hypothesis: ____________________________
Experimental Group: ____________________________
Control Group: ____________________________
Manipulated Variable (IV): ____________________________
Responding Variable (DV): ____________________________
Constants: ____________________________
Answer:
Hypothesis: IF the temperature is high, THEN the germination rate of radish seeds will increase.
Experimental Group: 20 Seeds in petri-dishes placed in the freezer and incubator each
Control Group: 20 seeds stored at room temperature
Manipulated Variable (IV): TEMPERATURE
Responding Variable (DV): GERMINATION RATE
Constants: Amount of water, same amount of time (2 weeks)
Explanation:
- The hypothesis is a testable explanation given to an observed problem. A possible hypothesis is IF the temperature is high, THEN the germination rate of radish seeds will increase.
- Independent or manipulated variable is the variable that is changed or manipulated variable in an experiment. The TEMPERATURE is the independent variable in this case.
- Dependent or responding variable is the variable that is measured in an experiment. In this case, the dependent variable is the GERMINATION RATE
- The experimental group is the group that receives the experimental treatment. In this case, the experimental group is the 20 Seeds in petri-dishes placed in the freezer and incubator each.
- The control group is the group that does not receive the experimental group. In this case, the control group is the 20 seeds stored or placed at room temperature.
- Constants are the variables that are kept unchanged throughout the experiment. In this case, the constants are Amount of water, same amount of time (2 weeks)

Cane toads are large, nonnative, poisonous toads in Australia. After cane
toads entered Australia, scientists observed that the average head size in a
population of toad-eating snakes was getting smaller. Snakes with smaller
heads are not able to eat the large cane toads. What type of situation is this?
O A. Disruptive selection
B. Species richness
C. Directional selection
D. Genetic variation
The answer you are looking for is C
Natural selection is a process by which the organisms adjust to the variation in the environmental conditions so they can endure and thrive in the altered conditions.
The correct answer is:
Option C. Directional selection
This can be explained as:
Directional selection is a negative form of natural selection in which the inhabitants of one species is favoured over another.The species with better trait characteristics will be favoured over the organism with less preferred attributes.The allele recurrence in directional assortment shifts over time.Therefore, toads with better traits (head size) are favoured over snakes with smaller mouth sizes.

I NEED HELP ASAP Sensors on a spider's legs feel the vibrations of a trapped insect and relay the information to the spider's brain through nerve electrical signals. For nerve cells to maintain these electrical potentials, sodium must be removed from the cell and potassium must be moved into the cell. Describe why this process is a form of active transport and what is required for active transport to occur?
Answer:
Please find the explanation below
- Energy (ATP) is needed for active transport to occur
Explanation:
According to this question, sensor's on a spider's legs relay information via nerve electrical signals to the brain when the vibrations of a trapped insect is felt. However, for nerve cells to maintain this electric potential, ACTIVE TRANSPORT must be carried out by removing sodium from the cell and potassium must be moved into the cell.
This is a form of ACTIVE TRANSPORT because pottasium ions are moved into the cell against concentration gradient i.e. from a region where it is in low concentration to where it is in high concentration. This active transport process is usually accompanied by the use of energy in form of ATP.

Answer:
The nucleus of a dividing cell is dense and spherical. It is comparatively larger in size during synthetic phase of cell cycle. Nuclear envelop also remain absent in many stages of nuclear division.
Explanation:
scientists determined that organisms of the genus spinoloricus we eukaryotes and not prokaryotes because spinoloricus cells have --
A. flagella
B. hereditary material
C. Cell walls
D. Nuclear Membranes
Scientists determined that organisms of the genus spinoloricus we eukaryotes and not prokaryotes because spinoloricus cells have cell walls. Thus, option C is correct.
What are the difference between eukaryotes and prokaryotes?Eukaryotes are distinguished from prokaryotes in that they organelles enclosed within a nuclear membrane. The organisms of spinoloricus are radically different from other known eukaryones in that they lack mitochondria and are able to exist in the absence of oxygen. However, their genetic material is contained within a nuclear membrane and they are therefore eukaryotes rather than prokaryotes.
Taking into consideration the main characteristic of each group, prokaryote, and eukaryote. In the first case, we have that it laks nucleus and has no sexual reproduction, meanwhile, the eukaryote has organelles and has sexual reproduction. Taking this into account we can proceed to answer each part.
Therefore, Scientists determined that organisms of the genus spinoloricus we eukaryotes and not prokaryotes because spinoloricus cells have cell walls. Thus, option C is correct.
