Answer:
c. They grow in different climates.
Explanation:
Answer: By Hormonal action and Nervous coordination
Explanation:
Hormones are substances produced by one tissue and conveyed by the bloodstream to another to effect physiological activity. Homeostasis is the maintenance of a stable internal environment in the body.
Body systems such as digestive, circulatory, excretory systems etc, all are coordinated to achieve a STABLE INTERNAL ENVIRONMENT by the aid of HORMONES AND/OR NERVOUS COORDINATION.
For Example: the vasodilation of blood vessels during hot weather, and the opposite action of vasoconstriction during cold weather are both controlled by Hormonal action and nervous coordination which leads to a stable body temperature preventing excess heat accumulation.
Also, Nervous system controls the body systems, such that the muscle contractions are joined to actions like sweating, breathing, respiration etc
So, to maintain homeostasis hormonal action and Nervous coordination is necessary.
Embryonic stem cells have the potential to produce regenerated tissues, such as skin. They could provide means of healing diseases such as type 1 diabetes where a particular cell has been lost or is malfunctioning.
Answer:
Natural selection is least likely to occur in this population if:
- The resources are continuously available
For a species to survive in an area, it is essential that the place has enough resources like nutrients, space, water etc. If these resources are available then there will be less chances of competition which will lead to lesser chances of natural selection.
- The number of of death rates is equal to the number of of birth rates
In an balanced ecosystem, the number of birth rates is equal to the number of death rates for a population. If the number of death rates is lesser to the number of birth rates then the competition for resources will lead to natural selection.
Carbon cycle, one of the most important elements that make up the structure of living things in an ecosystem carbon. Carbon is found in the structure of all organic compounds in living things.
Earth is important warehouses;
Atmospheric CO2In the waters of CO2 and HCO3-Land, usually coal, is the structure of the oil and limestone.<span>Photosynthesis by plants using airborne CO2 and O2 is converted to organic compounds. By participating in CO2 carbon all live in the structure of the building is used as a raw organic food energy and structure. In respiratory events again returned to the atmosphere as CO2. If a portion of the carbon is deposited on the ground layer mineral or dead plants and animals through the soil into the organic waste. Here are separated by saprophytes live or coal goes back into the atmosphere through the use of fossil fuels such as oil. However, excessive use of fossil fuels in the atmosphere the CO2 greenhouse effect climate change will bring about in the world, raises a few degrees increase and the consequent danger of melting glaciers at the poles of the temperature.</span><span />
