Answer: Migration, because species move to other places for food or a better or more suitable habitat and sometimes their is other species there.
Different ecological and biogeographical causes lead to different populations of the same species living in different environments. Ecological factors include intraspecific competition, migration, resource searching, habitat destruction, among others. Biogeographical dispersion involves wider areas and time factor. Human action is also a cause of dispersion.
-----------------------------------
Dispersion can be defined as the dissemination and distancing process of some individuals from others. It refers to the change in an organism's range or distribution area.
Different ecological and biogeographical processes might be involved in organisms' dispersion.
Ecological processes involve intraspecific competition for resources, habitat destruction, lack of resources -food or water-, among others. This is an intra-area, moderate dispersion that reduces competition and increases niche findings. It involves daily and seasonal migration and territoriality. Biogeographical processes refer to bigger changes that involve wider areas and time. It includes the historical factor, besides migration. This is an extra-area dispersion process.→ Jumping dispersion refers to a few individuals, in a short time, that can cross a barrier and occupy a new area. In this situation, the establishment is not always for sure. They must reproduce and start a new population of a certain size that can survive the new conditions.
→ Diffusion refers to populations that, through many generations, explores and expands in new regions with favorable conditions.
→ Secular migration is the diffusion through thousands of generations.
Dispersion is also caused by human actions, following different interests and goals.When two populations of the same species migrate to new areas and adapt to different environmental pressures, they will probably suffer from the speciation process with time, becoming two different species.

Spend one minute writing an explanation of
the FUNCTION of enzymes. YOU MUST USE
THE WORDS CATALYST, ACTIVATION
ENERGY, RECYCLABLE
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.

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

Select all that apply. The birds breed with each other where their territories overlap. The birds breed with each other where their territories overlap. The birds show differences in mating songs and behaviors. The birds show differences in mating songs and behaviors. The birds do not breed with each other where their territories overlap. The birds do not breed with each other where their territories overlap. The birds compete for food and nesting sites. The birds compete for food and nesting sites.
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.

#2
Sharks may be one of the most important species on Earth. They have been maintaining our oceans for over 400 millions years.
#3
Sharks have evolved and changed much over millions of years. However many sharks today still share some of the features as sharks from millions of years ago.
#4
Sharks have been in our oceans for over 400 million years. Some of the earliest sharks were discovered dating back to the Devonian age.
#5
Sharks have survived five massive planet extinction events. These extinction events killed most life on earth and the last one around 65 million yeas ago killed the dinosaurs.
#6
There are over 500 species of shark.
#7
It is believed that each whale shark's pattern is unique, like a human's fingerprint.
#8
Sharks do not have bones. Instead, they have cartilage, that's what makes up human noses and ears
#9
According to the Smit.hsonian, there are over 500 known shark species, though many are endangered or declining due to various factors like overfishing.
#10
Your odds of getting attacked and killed by a shark are 1 in 3,748,067. In a lifetime, you are more likely to die from fireworks or lightning. Whereas over 100 million sharks are killed every year by humans.
#11
Whale sharks are the world’s biggest fish.
#12
Sharks mature slowly and reach reproductive age anywhere from 12 to 15 years.
#13
Hammerhead sharks' eyes are on the sides of their heads, so they have nearly a 360-degree sight line. Their panoramic view of the undersea world is inhibited by two blind spots, one in front of the snout and the other directly behind the head.
#14
Sharks predate the dinosaurs by 200 million years.
#15
Great whites can detect one drop of blood in 25 gal (100 L) of water and can sense even tiny amounts of blood in the water up to 3 mi (5 km) away.
