Answer:
B- False
Explanation:
Pesticides can contaminate soil, water, turf, and other vegetation. In addition to killing insects or weeds, pesticides can be toxic to a host of other organisms including birds, fish, beneficial insects, and non-target plants. Soil can be degraded and the community of organisms living in the soil can be damaged by the misuse or over use of pesticides. Some pesticides are more toxic to soil organisms than others.

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.

Explain how fossil fuels found in the Earth's crust are ultimately the result of biological processes.
Answer:
Fossil fuels are formed when organic matter such as the remains of animals and plants are buried and sequestered deep underground. The energy stored in these once-living things, as well as the process of being buried, causes the organic material to undergo a series of chemical transformations.

Which of the following is the most obvious sign of cluster distribution in termites? a. They are insects. b. They are detritivores. c. They are social insects. d. Many species of termites are considered pests.
Answer:
C
Explanation:
The most obvious sign of cluster distribution in termites is they are social insects. The correct option is c.
What is cluster distribution?In cluster sampling, a population is divided into clusters, which are smaller groups. They then choose a sample at random from these clusters. Often employed to investigate huge populations, particularly those that are extensively geographically distributed, cluster sampling is a probability sampling technique.
Termite colonies can contain anywhere between 100 and 1,000 individuals, with the larger species typically having a larger colony size. However, some termite colonies, including those with a large population, can reach millions of members.
Therefore, the correct option is c. They are social insects.

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.

50 points: write 3 paragraphs on the difference of asexual and sexual reproduction and why is asexual better
Answer:
When an organism makes more of itself without the exchang of genetic information with another organism through sex, the reproduction is asexual.while
In sexual reproduction, the exchange of dna and other genetic material is required as it involves two separate organisms.Finally
Asexual is better in terms of time, less energy and only one organism (the parent cell) is needed for the process.Phosphatidate (phosphatidic acid) is a precursor in the synthesis of some lipids. Phosphatidate (phosphatidic acid) is a branched molecule. The core of the molecule is a three carbon chain. Carbon one is single bonded to two hydrogens, and a side chain. The side chain is oxygen single bonded to carbon. The carbon is double bonded to oxygen and an R 1 side chain. Carbon two of the core chain is single bonded 1 hydrogen and to oxygen which is single bonded to carbon. The carbon is double bonded to oxygen and single bonded to an R 2 side chain. Carbon three is single bonded to two hydrogens and a phosphate group. P O 4 2 minus. Phosphatidate (phosphatidic acid) Identify the lipids that have phosphatidate as a precursor.

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.

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.
