How can scientists measure the amount of carbon in soils?

Answer: (A) Narrowing of the artery causes the velocity to increase and the hydrostatic pressure to decrease.

Explanation:

Atherosclerosis is a disease which allows plaque to build up inside the arteries of a person. Arteries are responsible to carry oxygen-rich blood to heart and other areas of the body.  

Plaque consists of cholesterol, calcium, fat, and other substances which are present in the blood. Through time, the plaque hardens the arteries and narrows them. That restricts the oxygen-rich blood flow to your organs and to other parts of your body.  

Atherosclerosis can cause serious problems, including stroke and heart attack.

Hence the correct option is  (A).

Answer:

I can confirm that the answer is less and the answer to the question before that is Only glucose (smaller molecules)

Starch has a larger molecule size than glucose so you can conclude that larger molecules are less likely than smaller molecules to diffuse across a semipermeable membrane. The correct option is A.

One of the main sources of dietary energy for people is starch, a type of carbohydrate that is frequently found in nature.

Selectively permeable, a semipermeable membrane permits some molecules to pass through while obstructing others.

The presence of particular transport proteins controls the kind and size of molecules that can flow through a membrane, which determines its permeability.

Therefore, even if starch has a bigger molecular size than glucose, this does not necessarily entail that it will diffuse more slowly through a semipermeable barrier.

The gradient of starch content and the membrane's permeability to starch, both of which can be altered by transport proteins, will determine whether starch can diffuse over a semipermeable membrane.

Thus, the correct option is A.

Environmental science

Environmental science is defined as study of relationships of the natural world and organisms and their environments.

Environmental science considered an interdisciplinary field?

Environmental science is interdisciplinary because each and every scientist should know the concepts of population dynamics, biology, economics, and energy, chemistry, etc. to handle the environmental issues.

What is scientific inquiry?

Scientific inquiry defines the diverse ways in which the scientists study about the natural world and provide the explanations for their work.

What does CONPTT stand for?

CONPTT stands for consistent, Observable, Natural, Predictable, Testable, And Tentative.

“science is and science is not”

A non- science is the study that is not scientific and that is not a natural science or a science that is an object of scientific inquiry.

Inference is the act of inferring and observation is the act or instance of noticing .

What is a food web? What is a food chain? How are they different?

A food web consists of many food chains and the food chains has one path as animals find food.

explain the 10% rule.

The 10 % law states that the transfer of energy from one trophic level to the other.

If you 600 million calories were available to the primary consumers, approximately how many calories would be available to the quaternary consumers?

The primary consumers obtain only a fraction of solar energy about 10% that is captured by the producers they eat.

Environmental science is the study of interactions between humans and the environment. It is an interdisciplinary field that incorporates knowledge from various scientific disciplines. The 10% rule states that only 10% of energy is transferred between trophic levels in a food chain or food web.

Environmental science is the study of the interactions between humans and their environment. It involves studying topics such as natural resource management, pollution control, and conservation of biodiversity.

Environmental science is considered an interdisciplinary field because it incorporates knowledge and methods from various scientific disciplines, such as biology, chemistry, physics, and geology, to understand and address environmental issues.

Scientific inquiry is the process of asking questions, conducting experiments, and gathering evidence to understand natural phenomena.

CONPTT stands for Consistency, Observation, Natural Cause, Prediction, Testability, and Tentativeness, which are the key principles of scientific inquiry.

The difference between an observation and an inference is that an observation is something directly observed or measured using the five senses, while an inference is a logical interpretation or conclusion based on observations and prior knowledge.

A food web is a network of interconnected food chains that shows the flow of energy from one organism to another in an ecosystem, while a food chain is a linear sequence of organisms where each organism is eaten by the next organism in the chain.

The 10% rule states that only about 10% of the energy from one trophic level is transferred to the next trophic level. This means that as energy flows through a food chain or food web, there is a decrease in the amount of energy available at each successive trophic level.

Based on the 10% rule, if 600 million calories were available to the primary consumers, approximately 60 million calories would be available to the quaternary consumers. This is calculated by multiplying the energy available at the previous trophic level by 0.1.

Final answer:

The telescope is the instrument scientists invented to study the night sky, enabling significant advancements in astronomy since its invention around 1600. It allows for greater magnification and resolution to observe previously unseen celestial bodies. Galileo was among the first to use it for such studies, leading to groundbreaking discoveries.

Explanation:

Scientists invented the telescope to study the different objects in the night sky. The telescope was created around 1600 and was pivotal in advancing our understanding of astronomy. It gathers more light than the human eye can, allowing us to see dim objects with greater magnification and better resolution. The Greeks and Romans laid the foundation of astronomy which was enhanced significantly with the invention of telescopes.

Before telescopes, ancient civilizations observed the night sky to keep track of time and seasons, giving names to patterns of stars known as constellations. These constellations still help astronomers today. Ancient observatories were sites dedicated to monitoring celestial objects but were limited to the human eye's capabilities. The invention of the telescope allowed for the observation of celestial bodies that were previously beyond our sight.

Famous astronomer Galileo was one of the first to use a telescope to study the heavens, leading to critical discoveries such as the moons of Jupiter and the intricate details of the Milky Way. Today, although the night sky has been obscured for many by artificial lighting, telescopes continue to play a crucial role in the exploration of the universe.

Answer: A. tunneling nanotubes

Explanation:

A tunnelling nanotube (TNT) also called membrane nanotube is a concept that has been applied to protrusions extending from the plasma membrane that enables different animal cells to interact over long distances, often over 100 μm between T cells.

There are two types of tunneling nanotube including one type of smaller than 0.7 micrometres in diameter which contains actin, and carries parts of plasma membrane in both directions between cells. The second type is larger than 0.7 μm that contains both microtubules and actin, and may carry cytoplasm components such as vesicles and organelles, including whole mitochondria, between cells.

TNT functions in the development of various diseases by allowing the movement of protein, pathogens aggregates and mitochondria.

Hence, the correct option is A. tunneling nanotubes.

Answer: Food storage

Explanation:

Stomach is a small pouch like structure which has the ability to store food temporarily.The storage of the food temporarily takes place in the stomach. The food that we eat reaches to the stomach by the help of food pipe.

Here, the food is stored until it is completely broken down into simpler form and enzymes act on them.

The food is then absorbed in the small intestine. But before this food is temporarily stored in the stomach where all the digestive juices and enzymes come to act on the food.

Answer: food storage

Explanation:

The stomach is one of the important parts of the digestive system. It has three main functions to be performed in the animal or human body. It acts as a temporary storage organ for food which passed from the esophagus to the stomach, facilitates the breakdown and mixing of food components with the digestive juices by contraction and relaxation of the stomach muscles and finally aids in digestion of food.

Based on above description, the mechanical and chemical digestion of food by the stomach the other function includes the food storage.

Answer: 16.7%

Explanation: Children and adolescents (ages 6 to 17 years) engage in 60 minutes or more of moderate-to-vigorous physical activity daily as described by the CDC in The Physical Activity Guidelines for Americans (second edition).

However, elementary and high schools usually run from 8 a.m to 3 pm (or 3.30pm in some cases) daily. High school students take six one-hour classes or four 90-minute classes and an hour lunch break daily.

Thus, the CDC recommends 60minutes of physical activities daily, which account to 16.7% of the total class duration (6 hours) per day.

Answer:

The renin angiotensin aldosterone system.

Explanation:

We would be speaking from time to time that Aldosterone would be in charge of increasing blood volume by increasing water consumption.

Aldosterone, a steroid hormone from the mineralocorticoid family, produced by the external section of the glomerular zone of the adrenal cortex in the adrenal gland, acts to conserve sodium, both secreting potassium and increasing blood pressure, the blood pressure is through the increase in blood volume, therefore through the increase in water consumption

Increased levels of antidiuretic hormone (ADH) stimulate the thirst mechanism, driving increased water intake.

Increased levels of antidiuretic hormone (ADH) stimulate the thirst mechanism, driving increased water intake. ADH is released by the hypothalamus in response to increased osmolality of the extracellular fluid, which indicates dehydration. When ADH levels rise, it signals the kidneys to retain water, and it also stimulates the thirst center in the brain, leading to the sensation of thirst and increased water consumption.

Pablo suffers from vertigo and dizziness, but he does not have any hearing problem. He went to his family doctor, who sent him to the otorrino. Why do you think this specialist should examine him, if he hears correctly?

Vertigo is a sensation of movement or spinning that is often described as dizziness.

Explanation:

There are two types of vertigos: the peripheral ones, that affect the vestibular system of the inner ear and the central ones, which are the ones that affect the brain; and the central vertigo, which is due to a problem in the brain, usually in the brain stem or the back of the brain or cerebellu. This is the reason why the peripheral should be treated by specialists in otorhinolaryngology and the central by neurologists.

Answer:

Shark is hyperosmotic relative to sea water.

Explanation:

The sharks that live in the marine environment do not need to drink sea water unlike others.

This is because the concentration of the urea and oxide is trimethyl amine gets deposited in the tissues of the shark which is hyper osmotic condition to the outside environment( sea water).

There is an adequate amount of potassium, sodium and chloride in the body of shark.

This is how the shark maintains the osmoregulatory mechanism in marine environment.

Explanation:

Answer:

Autosomal Recessive mode of inheritance

Explanation:

If both parents can roll their tongue and their child cannot, it means they are both heterozygote for the trait and since this trait skipped a generation, it can be said to be an autosomal recessive mode of inheritance and not an autosomal dominant mode of inheritance as the later does not skip generations.

Final answer:

In simple Mendelian inheritance, if both parents can roll their tongues (a dominant trait) but their child cannot, each parent must be heterozygous. The Hardy-Weinberg formula can be used to calculate the numbers of homozygous dominant, heterozygous, and homozygous recessive individuals in a population based on phenotype frequencies

Explanation:

When both parents have the ability to roll their tongues, but their child cannot, we're looking at a situation involving simple Mendelian inheritance of a dominant trait. Tongue rolling is expressed when an individual is either homozygous dominant (TT) or heterozygous (Tt), and the inability to roll the tongue is a recessive trait (tt). For the child to be unable to roll their tongue, each parent must have been heterozygous (Tt), thereby giving a 25% chance for any of their children to be homozygous recessive (tt) and unable to roll their tongues.

To apply this understanding to a population genetics problem, the Hardy-Weinberg formula can be used. In a small town of 1,500 people, with 500 able to roll their tongues, the formula can determine the frequency of the alleles and subsequently, the expected numbers of homozygous dominant, heterozygous, and homozygous recessive individuals. By knowing the frequency of the dominant phenotype, calculations can reveal the genotype frequencies.

C. Enables lymphocytes to develop into mature T cells.

Explanation:

The thymus gland is located behind the sternum between the lungs.

The hormone secreted by the thymus gland is known as thymosin which stimulates the development of T cells.

These T cells are disease fighting cells. They play a vital role in the lymphatic system protecting the body against autoimmunity, this is when the immune system turns against itself. T cells are otherwise known as T lymphocytes.

Answer:

C. ENABLE LYMPHOCYTES TO DEVELOP INTO MATURE T CELLS

Explanation:

Thymus gland is a gland that produces thymosin hormone which is necessary for the production and development of T cells which are essential in immune response against diseases and infections. Thymus gland is located anterior to the chest, behind the sternum and is not found functioning throughout lifespan but mostly at puberty. After puberty it shrinks and replaced by fats in the body. Thymus gland produces thymosin which converts white blood cells into T cells. White blood cells called lymphocytes pass through thymus in which they are transformed into developed T cells which are then released into lymph nodes from which they execute their immune functions.

Answer:

Only the cue ball lost energy, because when you think about it when the cue ball strikes the others it shoots from the triangle it was formed and the 15 balls shoot across the table until they stop but the cue ball is still at the hit position

Explanation:

Upon impact, kinetic energy and momentum from the cue ball are transferred to the ball it collided with in an elastic collision, where the total energy is conserved but redistributed. Some energy is lost to friction, heat, and sound, making answer B the most accurate.

When Barry struck the cue ball with his cue stick, the cue ball moved with a certain amount of kinetic energy and momentum toward the other stationary balls on the pool table. As the cue ball hit another ball, according to the conservation of momentum and energy in an elastic collision, the kinetic energy and momentum are transferred from the cue ball to the ball it hit. This means that the cue ball loses some of its energy to the other ball, but the total energy in the system is conserved; it is just redistributed among the two balls. In an ideal elastic collision on a frictionless table, no energy is lost; however, in the real world, some energy is always lost to sound, heat, and friction. Therefore, in response to the student question, the closest answer would be B. The cue ball and the ball it hit lost some energy to forces such as friction and sound, not to the other stationary balls.
