Thad rolls his bowling ball down the lane with a
force of 63 Newtons. If his ball has a mass of 7 kg,
what is the resulting acceleration of the ball?
35.
Answers
The acceleration of the ball is, 9m/s.
How, explain your answer briefly?Given data:
The mass of the bowling ball is, m = 7 kg.
The magnitude of force offered by ball is, F = 63 N.
The above problem is based on the Newton's second law of motion. According to the Newton's Second law of motion, the applied force is equal to the product of mass and acceleration of the body.
So,
F = ma
Solving as,
a = F/m
a = 63/7
Thus, we can conclude that the acceleration of the ball is, 9m/s.

Predict what will happen when a piece of algae (simple plant) from the ocean is placed in a beaker of fresh water. Be sure to include the appropriate vocabulary while you are explaining your answer including the salt and freshwater environments compared to the algae. (Hypertonic, hypotonic, isotonic).
Answers
When an algae from the ocean is placed in fresh water, the water environment around the algae will become hypotonic in comparison to the algae's cytoplasm.
What makes the ocean water hypotonic?The high concentration of salt and other solutes in the ocean water creates a hypertonic environment for the algae, while the low concentration of solutes in the freshwater creates a hypotonic environment.
This change in osmotic pressure will cause water to move into the algae cells, causing the cells to swell. If the water uptake becomes excessive, the cells may burst and the algae may die.
However, if the algae is able to adjust its internal salt concentration, it can survive in freshwater. This process is called osmoregulation.

Being nervous interferes with sexual arousal. Explain why, with reference to the sympathetic and parasympathetic nervous systems.
Answers
Answer:
When one is nervous activates the sympathetic system and the irrigation towards the cardiac and muscular zone is increased, increases the arterial tension and the respiratory rate.
That is why the blood or blood volume is dispersed in these organs to be able to render efficiently in a moment of stress or flight for the human.
When we have sexual intercourse and there is sexual excitement, a large part of the blood volume goes to the reproductive organs to be able to irrigate the area and produce said excitement, if we are stressed in an alert situation, it will be harmed by the priority body to irrigate the main areas like heart and muscle.
Explanation:
It is important to clarify that the physiological stress in humans is a normal situation, thanks to the presence of cortisol and it is what keeps us active, but if it increases due to anxiety or overwork, psychological problems, etc., it will no longer be physiological due to that is in excess.
Thus, sexual arousal will also be affected by the psychological impotence generated by excess mental stress outside the vascular pattern.
Asian carp is an invasive species of fish causing serious damage to native fish populations in the United States. Asian carp was initially imported to help control weeds and parasites incommercial ponds. A few years later, Asian carp began appearing in the Mississippi River and soon became well established throughout the river and in various bodies of water throughoutthe country. Residents of one particular town have observed a decrease in the bass population since the appearance of the Asian carp in their lake. They claim that the recent increase inAsian carp population has changed their aquatic ecosystem. What additional evidence would be needed to support this claim?A.Data on changes in the population of other aquatic species and abiotic factors after the appearance of the Asian carpB.Data on a change in the Asian carp population after a decrease in the bass populationC.Data on changes in the water level of the lake after the appearance of the Asian carpD.Data on a change in the land life population and abiotic factors after the appearance of the Asian carp
Answers
The correct answer is A. Data on changes in the population of other aquatic species and abiotic factors after the appearance of the Asian carp. Invasive species can change ecosystem function. To prove it, it is needed to record data on population abundance of native species, and abiotic parameters related to the invasive species. If there is a change in both issues after the introduction of the invasive species, we could say it is changing the ecosystem functioning.

Consider how lettuce or spinach placed in water becomes firm and crisp. Use what you have learned about cell membranes to explain this observation. Be sure to include homeostasis in your explanation.
Answers
Cell membrane is semi-permeable outer covering of an animal cell. Cell membrane allows the transport of substance into and out of the cell. When the spinach and lettuce are placed in water they become firm and crisp due to endo-osmosis of water.
What is a Cell Membrane?A cell membrane is the outermost covering in the animal cell and it is covered by the cell wall in the plant cells. Cell membrane is responsible for the transport of materials into and out of the cell.
Cell membrane is semi-permeable in nature that means it only allows some substances to pass through the membrane and block others. Osmosis and diffusion are the processes through which substance pass. When a cell is placed in water, the concentration of water is low inside the cell as compared to the solution. In this case, water travels from its high concentration to its low concentration into the plant cell and the leaves swell and become crisp.

Mutualistic Relationships
Mutualistic relationships are interactions where both organisms are benefitted. One example is bees and flowers. In this relationship, the bees get food in the form of nectar and the flowers are pollinated by the bees. Both organisms are benefitted mutually; the bees can make honey and the flowers can reproduce.
Other Symbiotic Relationships
There are 2 other forms of symbiotic relationships. The first is commensalism: where one organism benefits but the other is unaffected. The other is parasitism: where one organism benefits and the other is harmed.

How does skeletal muscle respond to the nervous signals to result in
movement?
Answers
Skeletal muscle responds to nervous signals by contracting and relaxing in a coordinated manner, which results in movement. When a nerve impulse, or action potential, travels to a skeletal muscle fiber, it triggers the release of a chemical called acetylcholine from the nerve ending. Acetylcholine then binds to receptors on the muscle fiber, causing the muscle to contract.
The process of muscle contraction begins with the sliding of thin filaments called actin and myosin past each other. The myosin filaments have small, knob-like structures called cross-bridges that bind to the actin filaments and pull them along, causing the muscle fiber to shorten. As the muscle fiber shortens, it generates force, which can be used to move the body or an external object.
When the nervous signal to the muscle is turned off, the muscle relaxes and the actin and myosin filaments return to their original positions. This process allows skeletal muscles to respond to nervous signals and produce movement in a controlled and coordinated manner.

explain how parasitism help shape biodiversity
Answers
Answer: parasitism can help shape biodiversity by exerting selective pressure on host populations and by contributing to the diversity of parasitic organisms themselves.
Explanation: Parasitism is a form of symbiotic relationship where one organism, the parasite, benefits while the other, the host, is harmed. Parasites can have a significant impact on the biodiversity of an ecosystem by selecting and shaping the characteristics of their host species.
Parasites have evolved to infect specific hosts, which means that their survival and reproduction are tied to the existence of their host. As a result, parasites can exert selective pressure on the host population, favoring certain traits and characteristics that make the hosts more resistant or susceptible to infection.
This selective pressure can lead to evolutionary changes in the host population, which can lead to increased genetic diversity. For example, if a parasite infects a population of fish and selects for fish that have more effective immune systems, then those fish will be more likely to survive and reproduce, passing on their advantageous traits to their offspring. This can ultimately lead to the development of new species.
Furthermore, parasites themselves can be incredibly diverse. Studies have shown that parasites can account for a significant percentage of the total biodiversity in an ecosystem. By infecting different hosts and adapting to different environments, parasites can influence the evolution of their hosts and contribute to overall biodiversity.
Answer:
Parasitism, in common with competition, facilitation, and predation, could regulate BD-EF relationships. Parasitism affects host phenotypes, including changes to host morphology, behavior, and physiology, which might increase intra- and interspecific functional diversity.
