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.

Answer:

1. Submit your observations of the chicken leg dissection.

The first thing that I saw was the skin. This one has bumps on it. Underneath, when I carefully cut it, I could see a yellow layer which is fat. Under the fat, there is a thick pink tissue, the muscles. The muscle is in contact with the bones and attached to them by the tendons. They look thin and white and are at the muscles' ends since they attach them to the bones.

2. Were you able to determine how the chicken moves?

Yes, muscles work in pairs, so when I pull from a specific tendon, the leg bends since the muscle contracts to do this movement. Then this muscle will relax, another muscle will contract itself, and a tendon will pull the bone to return the leg to a straight position.

When one of these muscles contracts, the other relaxes to allow the bone's movement in a specific direction. Then this muscle relaxes and allows the leg's movement in the opposite direction since the muscle that was lax before now is contracting itself to extend the leg. There are a flexor and an extensor muscle.

3. What characteristics of muscles help you determine the direction of the movement?

The characteristics that help me determine the movement's direction were:

By following the muscle, the tendon, and where it is in the joint, I could determine the movement's direction.

Explanation:

When we observe a chicken leg dissection, we can determine the components that it has and how all the elements work together to move the leg. Even though the mechanism and structure are not the same as in a human body, we can see how muscles, bones, tendons, and joints work not only in animals but also in humans to allow movement.

Explanation:

Ant breed faster than any other organism on earth, 20% of earth mass have land animals. Many ants are on the earth. Thus, option D is correct.  

Ants belongs to Formicide family  which is related to so called eusocial insects like bees and termites. It is appeared in the Cretaceous period that is more than 90 million years ago.

The diversity of ants is every where except Antarctica.

The body has three parts such as  a head, a meso-some and metasoma or gaster.

Ants are mostly omnivorous but can be scavengers , predators or herbivores based on ecological context.

The reproduction in which young, queens  fly during mating time, fertilize with male, this flight is called as nuptial flight.

Then queen lay eggs, then larvae emerge to become pupae, then adults such as workers, soldiers, males or other queens are produced.

Thus, option D is correct.

Answer:

The birds do not breed with each other where their territories overlap.

Explanation:

The correct answer would be that the birds do not breed with each other where their territories overlap.

A species consists of organisms that are phenotypically similar and are capable of mating to produce fertile progeny.

Hence, the first thing to establish that two organisms are not of the same species is the inability to breed with each other. If an eventuality occurs and they are able to breed, the resulting progeny would be invalid.

Therefore the fact that the golden-cheeked warbler and the black-throated green warbler do not breed with each other where their territories overlap is enough information to determine that the birds are separate species.

Answer:

Enzymes help speed up chemical reactions in the human body. They bind to molecules and alter them in specific ways. They are essential for respiration, digesting food, muscle and nerve function, among thousands of other roles.

What is the function of an enzyme? They allow chemical reactions to occur at normal body temperature fast enough to sustain life. They reduce the activation energy needed to start a chemical reaction.

There are four steps in the process of an enzyme working. (1) An enzyme and a SUBSTRATE are in the same area. The substrate is the biological molecule that the enzyme will work on. (2) The enzyme grabs onto the substrate with a special area called the ACTIVE SITE.

Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life. The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.

Hope you get done. friend me back. and can I have brainliest

Explanation:

To get diversity in individuals, genetic differences are required, and different phenotypes must be expressed. Since sexual reproduction is more conducive to driving evolution than asexual reproduction, much more genetic diversity is available for natural selection to work on. Evolution can happen over time.

Plutonium

Neptunium

osmium

let me know if it's correct or not, these were the only ones I could think of.

Few natural elements have a greater density than gold are plutonium, neptunium, and osmium.

An element is define as a type of substance that is impossible to  break into smaller pieces by the help of chemical process. There are several rules that should be followed at the time of assinging name of the elements. The first rule is name of the element is not a proper noun. The second rule is the symbols of the element that must be of one or more than one symbol.

Density is define as the mass per unit volume it means that 1 kg mass present in 1 meter cube is called density, density is also states that the how compact an material.

Mathematically

Density = mass/volume

S.I unit of density is kg/m^3

Density is higher in solid as compare to liquid and density of liquid is higher than gas so density is in order of SOLID>LIQUID>GAS. So we know that solid is compact in nature as compare to liquid and gas.

Therefore, Few natural elements have a greater density than gold are plutonium, neptunium, and osmium.
