Answer:
Sexual Reproduction.
Explanation:
Genetic variety in a population makes the population better able to cope with changes in the environment.
The two individuals which are having the name Pinus palustris and Pinus elliottii belong to the same genus but are different species as their second name is unique.
Binomial nomenclature is a system of naming living organisms such as plantsand animals in which each of the species is given a name which consist of two terms of which the first name is the genus name and the second name is the species name itself.
All the living organisms have two names by which they are called, one is the common name and the other is scientific name. Here, the individuals which have the name Pinus palustris and Pinus elliottii belong to the same genus but are different species as their second name is different.

Answer:
The Binomial nomenclature is the method by which the naming of the organism is done. Each and every organism is known by two names. One is the local name and other is global name which is used by all.
Explanation:
Explanation: The plants and animals are named according to the binomial nomenclature in which the first word of the name describes the genus of the organism and the second word represents the species of the organism.
Here, the individual having the name Pinus palustris and Pinus elliottii belong to the same same genus but different species as their first name is same.
-be inorganic
-be organic
-be made naturally
-have a crystalline structure
-be a solid
-have a homogenous composition
Answer:
Mineral refers to the substance naturally formed in the environment.
They usually have homogenous with a definite however not fixed chemical composition.
They are solid and inorganic in nature.
They are required by our body in a trace amounts in order to maintain normal physiology of the body.
Examples: aluminium, zinc, magnesium, sodium, potassium etc.
Hence, all options are correct except organic.
b: Arteries always carry oxygenated blood.
c: Veins always carry deoxygenated blood.
d: Arteries carry blood away from the heart.
e: Veins carry blood toward the heart.
Answer:
a: There is a unidirectional blood flow.
d: Arteries carry blood away from the heart.
e: Veins carry blood toward the heart.
Explanation:
The human circulatory system includes three main types of blood vessels: arteries, veins, and capillaries. Arteries are the blood vessels that carry the oxygenated blood from the heart to various body tissues. Veins are the blood vessels that pick the deoxygenated blood from body tissues and deliver to the heart. Vena cava is the largest vein that reaches the right atrium of the heart and delivers the deoxygenated blood.
The blood from the right atrium is carried to the right ventricle and finally lungs via the pulmonary artery for oxygenated. The oxygenated blood from the lungs is carried to the left atrium of the heart by a pulmonary vein. The oxygenated blood from the left atrium is carried to the left ventricle and finally to the body tissues by branches of the aorta. This unidirectional blood circulation of the human body ensures efficient delivery of oxygenated blood to body tissues.
In general, blood follows a unidirectional flow in the body with arteries carrying blood away from the heart and veins bringing it back. Though it's typical for arteries to carry oxygenated blood and veins to transport deoxygenated blood, there are noteworthy exceptions, like in the case of pulmonary arteries and veins.
Characterizing blood flow in the human body involves understanding the function and direction of blood movement in arteries and veins. a: There is a unidirectional blood flow is correct; blood does flow in a single direction, moving out from the heart, delivering oxygen and nutrients to tissues, then returning the blood to the heart. d: Arteries carry blood away from the heart and e: Veins carry blood toward the heart are both accurate characterizations of blood flow as well.
However, b: Arteries always carry oxygenated blood and c: Veins always carry deoxygenated blood are not completely true. While it's generally correct that arteries carry oxygenated blood and veins carry deoxygenated blood, there are exceptions. For example, the pulmonary arteries carry deoxygenated blood from the heart to the lungs to pick up oxygen and expel carbon dioxide, while the pulmonary veins carry oxygenated blood back to the heart.
