1. Which activity is an example of exercise?

swimming
listening to music
reading a book
sleeping

Answers

Answer 1

Swimming is an example of exercise. Exercise is defined as any physical activity that is planned, structured, and repetitive and that has the goal of improving or maintaining physical fitness. Hence option A is correct.

Swimming is a low-impact, aerobic exercise that can help improve cardiovascular health, build endurance, and strengthen muscles.

When swimming, the body is engaged in a physical activity that requires the use of large muscle groups, such as the arms, legs, and core. This activity increases heart rate and breathing rate, which provides cardiovascular benefits.

Additionally, swimming can help build muscle strength and endurance, as the resistance of the water provides a challenging workout.

In contrast, listening to music, reading a book, and sleeping are not examples of exercise. While these activities may be enjoyable and have other benefits, they do not involve the physical exertion required for exercise.

Hence option A is correct.

Both have tentacles.

Answers

Answer:

They typically have a tough, spiny surface, which inspired their name (in Greek, echinos means “spiny” and derma means “skin”). They also have the unusual ability to regrow lost body parts, and sea stars and brittle stars can regrow arms if broken off or eaten

Explanation:

Sea stars and brittle stars both use tube feet to catch prey. Therefore, option C is correct.

What are sea stars and brittle stars?

Echinoderms with a star form that belongs to the class Asteroidea are known as starfish or sea stars. These terms are frequently used incorrectly to refer to ophiuroids, which are properly called brittle stars or basket stars in common usage. Due to their membership in the class Asteroidea, starfish are also referred to as asteroids.

The benthic (bottom-feeding) fauna of the maritime environment includes brittle stars. They belong to the Phylum Echinodermata, which includes marine organisms with radial symmetry, five components, and frequent spines. They are commonly referred to as echinoderms.

Sea stars and brittle stars both use tube feet to catch prey. Therefore, option C is correct.

Answers

Answer:

Biogenic and thermogenic

Explanation:

Biogenic and thermogenic are the two ways or mechanism that is responsible for formation of natural gas. Biogenic gas is formed with the help of methanogenic organisms that is present in marshes, bogs, landfills, and shallow sediments. Thermogenic gas is formed from organic matter that is buried in the deeper earth where the temperature and pressure are very high.

The organic pathway of the carbon cycle is the pathway in which carbon moves from atmosphere, through producers, herbivores and other organisms in the ecosystems, and converted back to the atmosphere.

In geological pathway, carbon moves from the atmosphere, through the ocean to rocks and the mantle, and then back to the atmosphere.

B.Convection currents in magma are a result of density differences.

C. Convection currents play a role in the movement of Earth’s inner core.

D. Convection currents in magma are caused by temperature differences.

Answers

Answer: C....Convection currents play a role in the movement of Earth’s inner core

The statement which is not correct with regard to convection currents is as follows:

Convection currents play a role in the movement of Earth’s inner core.

Thus, the correct option for this question is C.

What is Convection current?

Convection current may be defined as a procedure that significantly involves the movement of energy from one place to another. It is basically the existence of current in a fluid through convection.

The inner core of the earth has appeared as solid as compared to other parts like the crust and mantle. Most liquid particles are definitely found on the mantle of the earth's surface.

Due to the presence of excessive liquid particles and compounds, the convection current is significantly noticed there.

Apart from this, magma is also a fluid that derives current through convection. It produces in a number of ways like magma driving plate tectonics, density differences in the magma, and temperature differences.

Convection currents are basically the movement of fluid with respect to temperature or density difference within the material.

Therefore, the correct option for this question is C.

what do the arguments for and against the use of stem cells in medical research share?​

Answers

Answer:   Stem cell research can potentially help treat a range of medical problems. It could lead humanity closer to better treatment and possibly cure a number of diseases:

Parkinson’s Disease

Alzheimer’s Disease

Heart Diseases, Stroke and Diabetes (Type 1)

Birth Defects

Spinal Cord Injuries

Replace or Repair Damaged Organs

Reduced Risk of Transplantation (You could possibly get a copy of your own heart in a heart-transplantation in the future

Stem cells may play a major role in cancer

Better treatment of these diseases could also give significant social benefits for individuals and economic gains for society

Cons

"We should not mess with human life."

"Humans should not be trying to play God"

Some argue that stem cell research in the far future can lead to knowledge on how to clone humans. It is hard to say whether this is true, but we have seen devastating consequences of other research-programs, even with good intentions, such as nuclear research.

Stem cells are cells, which have the ability to transform into many different types of cells. The stems cells have the potential to specialize in any type.

The stem cells are extensively used for research, curing diseases, and especially in developing prosthetics. The stems cells provide new cells for the growth and development of the replaced and damaged cells.

The arguments for and against the use of stem cells are:

Arguments for the use of stem cells in medical research are:

1. The stem cells enhance the growth and development of healthy skin tissue.

2. The cells can be used to enhance the production of collagen.

3. The study of stem cells helps in understanding the causes of disease.

Arguments against the use of stem cells in medical research are:

1. The use of stem cells for research harms human life and dignity.

2. People believe that killing blastocysts or stem cells is equal to taking a human life.

3. However, the transplant of stem cells can be rejected by the patient's body, therefore, can cost the life of the patient.

Therefore, the use of stem cells for research can be fruitful or disadvantageous.

Find the laplace transform of f(t) = t^2 e^ 2t cos(3t) On January 2, Wabash Construction Company, a general contractor, executed a written contract with Anderson Brick, Inc., a subcontractor. The contract relates to a major "strip mall" building project in Morgantown, and Wabash faces a deadline of October 31 in its contract with The Mackie Consortium, L.L.C., the owners of the new mall. In the agreement between Wabash and Anderson, the parties stipulate that "time is of the essence" in terms of performance of the bricklaying work, and that the deadline for Andersons completion of the bricklaying work is July 15. There is also a "liquidated damages" clause in the contract between Wabash and Anderson, indicating that if the work is not completed by July 15, Anderson will pay $2,000 in damages for every day the bricklaying is not completed beyond July 15.Anderson does not complete the bricklaying work by July 15. In fact, the project is not finished until August 30, and Wabash now claims liquidated damages from Anderson in the amount of $92,000 (representing 46 days beyond the July 15 deadline, multiplied by $2,000 per day.) Anderson refuses to pay the $92,000, and Wabash sues.At trial, Andersons attorney seeks to introduce the following evidence: 1) the testimony of Henry Anderson, Andersons owner, who is willing to testify under oath that at the time of the signing of the contract, Wabashs general manager, Fred Stein, said "Pay no attention to the July 15 deadline in the contract; if you need more time, all you have to do is ask;" and 2) a crumpled index card, purportedly in Fred Steins handwriting, indicating "no hard and fast deadline on Anderson brick work."Should the trial court judge admit the foregoing evidence?
