Answer:

10 m/s/s or m/s²

Explanation:

Acceleration can be calculated by using the formula;

a = v - u/t

Where;

a = acceleration (m/s²)

v = final velocity (m/s)

u = initial velocity (m/s)

t = time (s)

In other terms, acceleration (a) can be represented as ∆V/t.

According to this question, a ball accelerates from 10 m/s (u) to 30 m/s (v) in 2 seconds. Hence, the acceleration of the ball is as follows:

a = 30 - 10/2

a = 20/2

a = 10m/s².

Answer:

\(\boxed {\boxed {\sf C. \ 2.5 \ grams }}\)

Explanation:

We are asked to find how much of a 40 gram sample remains after 12 years.

Iron-55 has a half-life of 3 years. Therefore, after 12 years, 4 half-lives have been completed.

Every time a half-life is completed, half of the sample's mass decays. Remember we start with a 40 gram sample.

There is also a formula that can be used to solve this problem.

\(A= A_o(\frac {1}{2})^{\frac{t}{hl}\)

Where A₀ is the initial amount, t is the time, and hl is the half-life.

We know 40 grams is the inital amount, 12 years is the time, and 3 years is the halflife.

\(A= 40 \ g (\frac{1}{2})^\frac{12}{3}\)

\(A= 40 \ g (\frac{1}{2})^4\)

\(A= 40 \ g * 0.0625\)

\(\bold {A= 2.5 \ g}\)

After 12 years, 2.5 grams of Iron-55 will remain.

In the past, some populations who consumed mostly corn (masa, corn tortillas, grits) avoided developing pellagra because of the use of limewater.

The populations who consumed mostly corn-based foods like masa, corn tortillas, and grits were able to avoid developing pellagra, a disease caused by niacin deficiency, due to the use of limewater. Limewater, also known as calcium hydroxide solution, was traditionally used in the processing of corn-based foods. When corn is soaked in limewater, it undergoes a process called nixtamalization, which increases the bioavailability of niacin (vitamin B3) and other nutrients in corn.

The alkaline nature of limewater helps to release niacin from the corn, making it more accessible for absorption by the body. By incorporating limewater in the preparation of corn-based foods, the populations were able to prevent or alleviate the symptoms of pellagra, which include dermatitis, diarrhea, and dementia.

AMD stands for Acid Mine Drainage. It is formed when sulfide minerals in rocks are exposed to air and water, resulting in the generation of sulfuric acid and dissolved metals. This acidic and metal-rich drainage can have detrimental effects on the environment, including water pollution and damage to aquatic ecosystems.

To manage dump construction and minimize the impact of AMD on the environment, several measures can be implemented:

Prevention: One of the primary approaches is to prevent or minimize the formation of AMD in the first place. This can be achieved by implementing proper waste management practices, including selecting suitable waste rock materials, limiting the exposure of sulfide minerals to air and water, and employing effective cover systems.

Neutralization: Implementing neutralization techniques can help mitigate the acidity of AMD. This involves treating the drainage with alkaline substances, such as lime or limestone, to raise the pH and reduce its harmful effects on the environment.

Containment: Constructing and maintaining effective containment systems is crucial to prevent AMD from infiltrating surrounding soils and water bodies. This can include using impermeable liners, such as clay or synthetic materials, to prevent the leaching of acidic drainage.

Water management: Proper water management is essential to control the movement and accumulation of AMD. This may involve implementing diversion channels, collection systems, and treatment facilities to contain and treat the acidic drainage before it enters the environment.

Monitoring and maintenance: Regular monitoring of water quality, pH levels, and metal concentrations is necessary to detect any potential AMD issues and take appropriate corrective measures. Ongoing maintenance and management of dump sites are crucial to ensure the effectiveness of preventive and mitigation measures.

AMD, or Acid Mine Drainage, refers to the acidic and metal-rich drainage that is formed when sulfide minerals, typically found in rocks associated with mining activities, come into contact with air and water. The exposure of sulfide minerals to oxygen and moisture leads to chemical reactions, resulting in the generation of sulfuric acid. This acid then dissolves metals present in the rocks, such as iron, zinc, and copper, which further contributes to the contamination of water bodies and soil.

The management of waste rock dumps is essential to minimize the impact of AMD on the environment. Dump construction should incorporate measures that aim to prevent the formation of AMD, neutralize its acidity, contain its spread, and manage water flow effectively. These strategies help to minimize the release of acid drainage and metals into the environment, protecting water quality and ecosystems.

The management of waste rock dumps is critical in mitigating the formation and impact of Acid Mine Drainage (AMD). By implementing preventive measures, neutralization techniques, containment systems, effective water management, and regular monitoring, the environmental impact of AMD can be minimized. Adhering to best practices and regulations ensures responsible waste management and helps safeguard water resources and ecosystems.

Answer:

When a muscle relaxes,

crossbridges stop forming and muscle elasticity returns the muscle to rest length.

Explanation:

Relaxation occurs when stimulation of the nerve stops. Calcium is then pumped back into the sarcoplasmic reticulum breaking the link between actin and myosin. Actin and myosin return to their unbound state causing the muscle to relax. Alternatively relaxation will also occur when ATP is no longer available.

The mean arterial pressure (MAP) is not equal to (systolic pressure - diastolic pressure)/2 due to the non-linear pressure waveform. Systolic pressure represents the maximum pressure in the arteries during ventricular contraction, while diastolic pressure represents the minimum pressure during ventricular relaxation. MAP calculation takes into account the fact that the pressure during systole lasts longer than during diastole, resulting in a higher overall pressure.

why mean arterial pressure (MAP) is not equal to (systolic pressure - diastolic pressure)/2.
Mean arterial pressure is an important measure of the average blood pressure in a person's arteries during a single cardiac cycle. It's calculated using both systolic pressure (the pressure in the arteries when the heart is contracting) and diastolic pressure (the pressure in the arteries when the heart is relaxed). However, MAP is not a simple average of these two values because the heart spends more time in diastole (relaxation) than systole (contraction) during a cardiac cycle.
To calculate MAP, you can use this formula:
MAP = Diastolic Pressure + (1/3)(Systolic Pressure - Diastolic Pressure)
The reason for this formula is that the heart spends approximately 2/3 of the cardiac cycle in diastole and 1/3 in systole. Therefore, the diastolic pressure has a greater influence on the mean arterial pressure than the systolic pressure, which is why you don't simply average the two values.

Sun provides energy to producers. Energy flows from producers to consumers, and decomposers recycle nutrients.

Energy flow in an ecosystem begins with the Sun, which provides the primary source of energy. This solar energy is captured by the producers, such as plants and algae, through the process of photosynthesis. The energy is then transferred from the producers to the consumers, which include herbivores, carnivores, and omnivores, through consumption.

As the energy flows through different trophic levels, some of it is lost as heat during metabolic processes. Decomposers, such as bacteria and fungi, play a crucial role by breaking down dead organic matter and returning nutrients to the ecosystem through the process of decomposition. This nutrient recycling ensures the continuation of the energy flow and sustains the overall functioning of the ecosystem.

The protein acting as a hormone that regulates blood glucose is a) insulin.

Insulin is a hormone produced by the beta cells of the pancreas and plays a crucial role in regulating blood glucose levels. When blood glucose levels rise, such as after a meal, insulin is released into the bloodstream. Insulin acts on various tissues, particularly the liver, muscle, and adipose (fat) cells, promoting the uptake and storage of glucose. It helps lower blood glucose levels by facilitating the movement of glucose from the bloodstream into these cells, where it is either used for energy or stored as glycogen.

Insulin also suppresses the production of glucose by the liver. In individuals with diabetes, either insufficient insulin is produced (type 1 diabetes) or the body's cells become resistant to the effects of insulin (type 2 diabetes), leading to elevated blood glucose levels. Insulin therapy or other treatments are used to manage and control blood glucose in individuals with diabetes.

Answer:

The inner ear has two openings into the middle ear, both covered by membranes

Explanation:

The oval window lies between the middle ear and the vestibule, whilst the round window separates the middle ear from the scala tympani (part of the cochlear duct)

❈ The internal ear —

➥ The inner ear (also called the labyrinth) contains 2 main structures — the cochlea, which is involved in hearing, and the vestibular system (consisting of the 3 semicircular canals, saccule and utricle), which is responsible for maintaining balance.

➥ The cochlea is filled with fluid and contains the organ of Corti — a structure that contains thousands of specialised sensory hair cells with projections called cilia. The vibrations transmitted from the middle ear cause tiny waves to form in the inner ear fluid, which make the cilia vibrate.

➥ The hair cells then convert these vibrations into nerve impulses, or signals, which are sent via the auditory nerve to the brain, where they are interpreted as sound. The round window (fenestra cochlea) is a membrane that connects the cochlea with the middle ear. It helps dampen the vibrations in the cochlea.

➥ The semicircular canals also contain fluid and hair cells, but these hair cells are responsible for detecting movement rather than sound. When you move your head, the fluid within the semicircular canals (which sit at right angles to each other) also moves. This fluid motion is detected by the hair cells, which then send nerve impulses about the position of your head and body to the brain to allow you to maintain your balance.

➥ The utricle and saccule work in a similar way to the semicircular canals, allowing you to sense your body’s position relative to gravity and make postural adjustments as required.

❈ The middle ear —

➥ The middle ear is an air-filled space that contains 3 tiny bones (known as ossicles), called the malleus (hammer), incus and stapes (stirrup). Sound waves that reach the tympanic membrane cause it to vibrate.

➥ This vibration is then transmitted to the ossicles, which amplify the sound and pass on the vibration to the oval window (a thin membrane between the middle and inner ear). The Eustachian tube is a narrow tube that connects your middle ear to the back of your nose and throat (known as the nasopharynx). Its function is to allow air into the middle ear as well as drain mucus from the middle ear into the nasopharynx.

➥ When you swallow, your Eustachian tube opens up to allow air into the middle ear, so that the air pressure on either side of the tympanic membrane is the same. In situations when there is a sudden change in air pressure (e.g. during take-off and landing when travelling on a plane), the pressure in the middle ear is not the same as the outside air pressure.

➥ This can make your eardrum bulge or retract and less able to transmit vibrations, causing temporary hearing problems. By swallowing or ‘popping’ your ears, you can equalise the pressure.
