Given their unique regenerative abilities, stem cells offer new potentials for treating diseases such as diabetes, and heart disease. Research on stem cells continues to advance knowledge about how an organism develops from a single cell and how healthy cells replace damaged cells in adult organisms.
Yes. Without stem cell research there would be alot more sick people. There would be alot more sick people because Stem-cell research is an area of research that studies the properties of stem cells and their potential use in medicine. As stem cells are the source of all tissues, understanding their properties helps in our understanding of the healthy and diseased body's developmental and homeostasis. Stem cells originate from two main sources: adult body tissues and embryos.

How does heat flow? Provide an example.
Explanation:
Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. ... Metal is a good conduction of heat. Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more. These molecules then bump into nearby particles and transfer some of their energy to them.
Answer:
Heat Flow. At one time heat was defined as "that which flows when two objects at different temperatures are placed in contact." Heat flows from high values to low values in an attempt to bring the two objects into thermal equilibrium. ... Heat will flow so as to equalize the temperature throughout the object.
Explanation:
Conduction: Heat transfers into your hands as you hold a hot cup of coffee. Convection: Heat transfers as the barista “steams” cold milk to make hot cocoa. Radiation: Reheating a cold cup of coffee in a microwave oven.
Lucy is traveling to the top of Pike's Peak. The elevation is 14,000 feet. At the base, her respiration rate is 12 breaths per minute. At the top of Pike's Peak, her respiration rate increases to 20 breaths per minute. Why does Lucy's respiration rate most likely increase at the higher elevation
Answer:
Lucy's respiration rate increases because of the decrease in the atmospheric pressure and the partial pressure of O₂.
Explanation:
As Lucy ascends, the atmospheric pressure decreases. The decrease in this pressure decreases the partial pressure of inspired O₂, which causes less oxygen saturation in the blood. As oxygen is essential for the vital functions of the body, the respiratory rate increases to valance the loss of oxygen. In other words, the oxygen that the body had in one inspiration, now it has to obtain with multiple breaths. The same happens with the CO₂ that Lucy expels from her body.

Idk this one is give u a brainlist if u answer right with explanation
Answer: the answer is A
Answer: A. Store the genetic instructions needed to specify traits
Explanation:
The answer would be A. because chromosomes contain genetic information in the form of genes, which helps to code for certain traits in an observed organism.
None of the other functions apply to DNA, thus A. would be the best option.

What is an example of phototropism?
Answer:
Explanation:
Positive phototropism is growth toward a light source, and negative phototropism is growth away from a light source. ... Sunflowers are a great example of positive phototropism, because not only do their stems curve toward the light but their flowers turn to face the sunlight as well.
A scientist studying fossils, found that identical freshwater reptiles about 1 meter long were found in both South America and Africa. Since, these animals couldn’t have swum hundreds of miles across the Atlantic Ocean, what is the best explanation for how fossils of this creature were found in both places?
options:
A:The animals evolved to become the same exact species even though they lived in different environments.
B:The animals walked from Africa to South America because there used to be large valley that separated the continents, which has now been filled by the Atlantic Ocean.
C:The ancestors of this creature used to be able to fly. They flew from Africa to South America and then evolved into the freshwater reptiles the scientist discovered.
D:South America and Africa used to form a single landmass that later split apart. The fossils found on both continents shared a single habitat.
GIVE BRAINLIEST IF RIGHTTTTT
Answer:
D
Explanation: this would make sense because they could not have evolved to become the same. Evolution does not work like that . The animals would not walk or fly they are water creatures and if they did that they would not evolve back down to fish .
The first trilobites found in China were discovered in a layer of rock called the Devonian Shale. If you were hunting for trilobites in Canada, what sort of rocks would you look for?
Answer:
Rocks which were underwater long time ago.
Explanation:
If we were hunting for trilobites in Canada, we look for those types of rocks where once water present on it because trilobites are the organisms which lived in the marine ecosystem so if they are present in marine so we have to look those rocks which were underwater millions of years ago. Trilobites are the extinct marine arthropods that were present around 521 million years ago.
The sort of rocks that will be looked at during hunt for trilobites in Canada is
in deep ocean floor.
Trilobites are referred to as marine invertebrates which went extinct and was
discovered in China in a layer of rock called Devonian Shale. Subsequent
search for them have been found in Limestone shales also.
Limestone shales have layers of limestone present and they can be found in
deep ocean floors, basins and floodplains. The trilobites however will most
likely be found in deep ocean floors as a result of them being fossilized.

A doctor is looking at a patient's blood under a
microscope. She notices several cells with
malfunctioning mitochondria. Why is this
important? Check all that apply.
Because unhealthy cells can lead to
unhealthy tissue and organs.
Because mitochondria carry oxygen around
the body.
Because unhealthy cells usually form healthy
tissue and organs.
Because malfunctioning organelles can lead
to diseased tissue.
Answer:
- Because unhealthy cells can lead to
unhealthy tissue and organs.
- Because malfunctioning organelles can lead to diseased tissue.
Explanation:
Cells are the basic and fundamental unit of life. In the organization of life, cells are the precursors of tissues. This means that a collection of cells with similar function gives TISSUES, which subsequently gives rise to ORGANS. Also, organelles are structures with specific function within the cell. A faulty organelle will result in a faulty cell, thereby, affecting the other levels of organizations.
According to this question, a doctor is looking at a patients blood under a microscope where she notices several cells with malfunctioning mitochondria. This is important because:
- Unhealthy cells can lead to unhealthy tissue and organs.
- Malfunctioning organelles in a cell can lead to a deficient cell, which in turn can lead to a diseased tissue.
Answer:
A and D
Because unhealthy cells can lead to unhealthy tissue and organs.
Because malfunctioning organelles can lead to diseased tissue.
