Answer:

d your heart beating faster

The correct option is A. leg jumping when it is hit by a reflex hammer is the only brain-free option. It's a spinal reflex - a quick response through the spinal cord without needing the brain to process information.

Only the leg jumping when it is hit by a reflex hammer skips the brain. It's a spinal reflex for a quick response, while the others (B, C, D) rely on the brain to receive info and tell your body what to do (breathing, temperature, heart rate).

The other options (B, C, and D) require the brain's involvement and are not spinal reflexes:

B. Deeper breathing when you need more oxygen: When your body senses low oxygen levels (through blood chemistry changes), the brain receives these signals and triggers deeper breaths to increase oxygen intake.

C. Body temperature rising when you have an infection:  During an infection, the immune system releases chemicals that signal the brain to increase the body's core temperature, a defense mechanism.

D. Heart beating faster when you are in danger: When you perceive danger, sensory information reaches the brain, which activates the nervous system, causing your heart rate to increase to prepare for action.

In all these options (B, C, and D), the brain plays a crucial role in interpreting signals and sending commands to organs for adjustments.

Digestion of a light meal typically takes 3 to 5 hours, starting from the stomach where it breaks down into chyme and passes through the ileocecal sphincter to the large intestine. The sphincter's relaxation is controlled by nerves and hormones triggered by stomach activity.

A light meal will typically digest within about 3 to 5 hours. The process starts in the stomach, where food is broken down into a substance called chyme. The food then passes through the ileocecal sphincter, a gate between the small and large intestines. This sphincter relaxes through the action of nerves and hormones, allowing food residue into the first part of the large intestine, the cecum.

The ileocecal sphincter is relaxed through two main factors. First, the digestive activity in the stomach provokes the gastroileal reflex, which increases ileal segmentation force. Second, the stomach releases the hormone gastrin, enhancing ileal motility and thus relaxing the ileocecal sphincter. After chyme passes through, backward pressure closes the sphincter, preventing backflow into the ileum.

Overall, the transit time and processing of the food through the stomach and small intestine usually takes 3 to 5 hours. However, retention time of food over the length of the whole intestine can be between 24 to 72 hours.

Answer:

It can either be instinctual or learned.

Explanation:

An Instinctual behavior is one that a living being knows from the moment of birth, such as breathing or eating, but a Learned behavior is a behavior or habit acquired by personal experience, like speaking, walking, or playing video games.

Behavioral adaptation in animals can be instinctual or learned.

Instinctual behaviors, not influenced by the environment, include innate responses such as mating systems or methods of communication. This kind of behavior is genetically embedded and could include actions like human babies grabbing a finger or birds migrating.

On the other hand, learned behaviors are influenced by environmental changes and previous experiences. Learning involves acquiring knowledge and skills through experience which enable an organism to adapt to its living conditions. Instances of learned behavior could include a creature's specific reactions to threats based on past encounters.

Therefore, instinctual behaviors provide a solid base of survival skills, while learned behaviors allow for versatility and adaptability in changing environments.

When the coal reaches its hardest and the darkest form then it is termed as anthracite.

Answer: Option D

Explanation:

The hardest among the coal is called as the anthracite. It has large amount of carbon atoms and it is also regarded as the best quality of coal that is being mined.

This is mostly prevalent in South Korea, North Korea, United states, United Nations, Canada etc. This is mainly used in the steel making process and is combined with many alloys for enhancing their property.

To find the price of bituminous coal per million BTU's, we need to follow these steps:
1. Convert the price from tons to pounds:
  - Since there are 2,000 pounds in a ton, we can multiply $52/ton by 2,000 to get the price per pound.
  - $52/ton * 2,000 pounds/ton = $104,000/pound
2. Convert the heat content from BTU/pound to BTU:
  - Since there are 12,000 BTU/pound, we can multiply the price per pound by 12,000 to get the price per BTU.
  - $104,000/pound * 12,000 BTU/pound = $1,248,000,000/BTU
3. Convert the price to per million BTU's:
  - Since there are 1,000,000 BTU's in a million BTU's, we can divide the price per BTU by 1,000,000 to get the price per million BTU's.
  - $1,248,000,000/BTU / 1,000,000 BTU = $1,248 per million BTU's
Therefore, at $52/ton, the price of bituminous coal per million BTU's is $1,248.

Answer:

most will have a cleft chin and some will have a non cleft.

Explanation:

Answer: 5 would have brown hair.

Explanation:

In the cross between two heterozygous black guinea pigs, out of 20 offspring, we can expect approximately 15 to have black hair and approximately 5 to have brown hair, following Mendelian genetics principles.

In genetics, a dominant allele masks the effect of the recessive allele making it less likely to appear in the offspring. In the cross of two heterozygous black guinea pigs, the four possible combinations of their alleles are BB, Bb, bB, and bb. The first three combinations will produce black offspring, while bb will give a brown guinea pig. This results in a 3:1 ratio, hence in the case of 20 offspring, about 15 would be expected to have black hair while 5 would have brown hair.

B) particulate matter!

Sunny~ ☺

Particulate matter is not involved in the chemical reaction, which produces smog.  

• The air pollution, which diminishes visibility is smog.  

• The majority of the smog that one sees today is the photochemical smog.  

• It is generated when sunlight reacts with atleast one volatile compound and nitrogen oxides in the atmosphere.  

• The nitrogen oxides come from coal power plants, factory emissions, and car exhaust.  

• The volatile compounds are discharged from paints, gasoline, and many cleaning solvents. When sunlight react with these chemicals, they produce ground level ozone or smog and airborne particles.  

• The mixture of solid particles and liquid droplets found in the air is known as the particulate matter.  

• The particulate matter has no role in the production of smog.  

Thus, the correct answer is option b, that is, particulate matter.

B) limiting factors

Explanation:

Phytoplankton, also known as microalgae, are similar to land-based plants in that they contain chlorophyll and require sunlight in order to live and grow. Most phytoplankton are buoyant and float in the upper part of the ocean, where sunlight penetrates the water. Phytoplankton also require inorganic nutrients such as nitrates, phosphates, and sulfur which they convert into proteins, fats, and carbohydrates.

In a balanced ecosystem, phytoplankton provide food for a wide range of sea creatures including krill, shrimp, snails, and jellyfish, that are in turn food for larger animals like sea turtles, fish and whales. However, under certain environmental conditions, such as the introduction of too many nutrients from land based sources of pollution, phytoplankton may grow out of control and form blooms.

These blooms can be problematic because the excess algae can block out sunlight, which is bad for plants like seagrasses that need sunlight to make food. Zooxanthallae, or symbiotic algae that live in the tissue of coral and supply coral with food, can also be impacted by algal blooms. Excess algae can also smother other critters living on the ocean floor.

The factors such as sunlight, nutrient, and water to survive all cinditions that for algae bloom which are called: B. limiting factors.

Limiting factors can be defined as those constrains that slows or stop the growth of a population. They may include food, biotic factors, or even competetion from other organisms in the environment for limited available resources.
