PLS ANSWER FAST! Which of these descriptions best contrasts safety knowledge for cows and horses? Horses have a definite flight zone, whereas cows do not Cows will startle at sudden movement or noise. but horses do not. Cows have 360-degree vision, but horses do not Cows have a definite flight zone, whereas horses do not.
Answer:
the descriptions best contrasts safety knowledge for cows and horses is the description that says "Cows have 360-degree vision, but horses do not Cows have a definite flight zone, whereas horses do not"
Explanation:
For horses, the size of the flight zone depends primarily on the tameness or familiarity of the horse with the handler. With frequent handling, the flight zone decreases in size and may even disappear. A horse that is approached head-on has a larger flight zone than if it is approached from the side.
When moving groups of cattle in open spaces. The flight zone is the animal's personal space, and the size of the flight zone is determined by the wildness or tameness of the animal. Completely tame animals have no flight zone and people can touch them.

Explain the contribution of antigenic determinant in false negative and false positive test
Answer:
The contribution of the antigenic determinant is given below:
Explanation:
Antigenic determinant or epitope is the part of the antigen that is recognized by the immune cells or antibodies such as the B- cells by binding to these cells and evokes the response in the host. The antibodies bind to the epitope segments only not to the entire antigen protein.
A false-positive test is a test where the result suggests that an individual has a specific condition but in reality not having such condition. opposite in the false-negative So, the antigenic determinant binds to the specific antibodies and shows wide significance to reduce the false-negative or false-positive.

What is the primary use of the sugars that the algae produce?
There are many reasons why all humans do not perceive sounds similarly in our environment, including adaptation, hearing loss and/or deafness.
For 2A-2D, first determine whether the scenario is an example of sensory adaptation, conduction deafness, sensorineural deafness, and/or central deafness.
Second, for the scenarios that are examples of deafness, explain briefly how the scenario leads to deafness (i.e., how does the scenario alter normal auditory processing). If you have selected sensory adaptation as an answer, explain briefly why the scenario does not fall under the categorization of deafness. Use your own words to briefly explain - simply listing definitions is not sufficient. (2.5 points each for matching, 5 points each for correct justification)
2A. Listening to excessive loud noises everyday over years that causes loss of stereocilia
2B. Hearing construction outside when it first begins, but no longer noticing the sound minutes later
2C. Difficulty understanding speech, but no damage to ears or ability to understand nonverbal sounds
2D. A hole in the tympanic membrane caused by an ear infection
Answer:
2A. central deafness
2B. sensory adaptation
2C. sensorineural deafness
2D. conduction deafness
Explanation:
2A. Listening to excessively loud noises every day over the years that causes loss of stereocilia is an example of central deafness.
Central deafness could lead to deafness either partially or completely of one or both ears due to persistent exposure of the eardrum to loud noise every day for years. when it happens in years that is gradual damage which is usually common compared to sudden deafness. Stereocilia can be damaged with a persistent loud noise.
2B. Hearing construction outside when it first begins but no longer noticing the sound minutes later is an example of sensory adaptation.
In sensory adaptation, the sensory system tends to get adapted to a change in the sound that comes from the environment usually with that sound remaining constant over time. The sensory system get used to the constant stimuli, in this case, the construction outside and with time the system tends to make the stimuli less sensitive.
Sensory adaptation does not fall under the categorization of deafness because, though prolonged exposure of the hears to loud noise could lead to deafness, Sensory adaptation is just an adaptive feature of the hearing system and it could be a loud or low sound or noises.
2C. Difficulty understanding speech, but no damage to ears or ability to understand nonverbal sounds are an example of sensorineural deafness.
Sensorineural deafness involves the ability to hear sound but not to understand speech. Sounds may not be clear but the sufferer could hear a loud noise and it is usually caused if the part of the hearing that collects impulses and sends them to the brain become damaged.
2D. A hole in the tympanic membrane caused by an ear infection is an example of conduction deafness.
The tympanic membrane is also known as the Eardrum, the vibration of this membrane after being hit by stimuli from sounds is part of the fore process to allow the interpretation of sound by the brain. So when there is a hole in the eardrum conduction deafness would occur as the sound wave from the environment is blocked failing to be conducted through the eardrum.

Explanation:
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)

Explanation:
Define “isotope” using mass number, atomic number, number of protons, neutrons and electrons. (PLEASE HURRY!)
Isotopes have different mass numbers due to different number of neutrons but same atomic number due to same number of electrons and protons.
What are isotopes?
Isotopes are defined as substances having same number of protons but different number of neutrons.Number of protons is characteristic for determining position of elements in the periodic table.
Since,all isotopes have the same number of protons and hence have same position.They have similar chemical properties as they have same number of electrons.
They find applications in the field of nuclear medicine and oil and gas research . There are 2 types of isotopes : stable and unstable
Unstable isotopes are radioactive and are called as radioisotopes.Some of these isotopes are man -made and hence also called as artificial isotopes.Every element has an isotope which is either man-made or natural .
Many properties of isotopes depend on mass which is measured in atomic mass unit. The difference in actual mass and mass number is called mass defect.

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.

The total volume of plant cells is often significantly greater than the total volume in animal cells. The most reasonable explanation for this observation is that
A) animal cells are spherical, whereas plant cells are elongated.
B) plant cells are capable of having a much higher surface-to-volume ratio than animal cells.
C) plant cells have a much more highly convoluted (folded) plasma membrane than animal cells.
D) plant cells contain a large vacuole that occupies much of the volume of the cell.
Answer:
D
Explanation:
In plant cells, the vacuoles are much larger than in animal cells. When a plant cell has stopped growing, there is usually one very large vacuole. Sometimes that vacuole can take up more than half of the cell's volume. The vacuole holds large amounts of water or food.
