Explanation:
Meiosis I has one diploid parent cell and ends with two haploid daughter cells, splitting the number of chromosomes in each cell. Meiosis II starts with two haploid parent cells and ends with four haploid daughter cells, maintaining the number of chromosomes in each cell.
Explanation:
Answer: The higher animals needs and internal transport system so that the innermost cells can get nutrition which cannot be left on diffusion and osmosis to transmit. They also needed an internal transport system and so that they get oxygen to the internal cell...
I hope you help :)
Answer:
Voltaire was a French Enlightenment writer, historian, and philosopher, who attacked the Catholic Church and advocated freedom of religion, freedom of expression, and separation of church and state.
Intelligence is the answer.
Humans are superior to every animal when it comes to intelligence, but there are many animals that are far more superior when it comes to speed and strength (a tiger for example) and there are animals that are far superior in sensory sensitivity as well (like a dogs sense of smell).
So your answer is intelligence.
Answer:
The abiotic characteristics of an ecosystem that affects man includes: Land surface, rainfall and relative humidity.
Explanation:
In the ecosystem, man occupies the terrestrial habitat which is affected by the abiotic factors listed above.
Abiotic (non- living) factors determine the type of biotic (living) community that is found in an ecosystem. These factors include Land surface, rainfall and relative humidity, just to mention a few.
--> LAND SURFACE: This is responsible for the marked variation in the vegetation of a place. For example, a mountain in the tropics may have a rain forest vegetation at it's base and an afroalpine vegetation near its peak. The gradient of the slope affects the growth of organisms. A steep slope encourage fast run - off of water and therefore encourages erosion, which results in shallow and infertile soil. This in turn AFFECT man's farming activities as there would be little to no crop yield.
--> RAINFALL: Water is a very important abiotic factor that affects life. The main source of water to terrestrial habitat is rainfall. When rain falls, a greater percentage of it sinks into the soil while the rest run- off into water bodies. Water is absorbed by root hairs into the plant and used for photosynthesis to produce food. The absence of rainfall in the environment of man could lead to drought which AFFECTS man negatively.
--> RELATIVE HUMIDITY: This is a measure of the amount of moisture in the atmosphere. It's usually high in hot wet regions. It affects the rate at which water evaporates from the body surfaces of organisms. Low relative humidity cause more water (sweat) to evaporate from body surfaces giving the human body a cooling effect. But in high relative humidity, the sweat cannot evaporate leaving the body feeling hot and sticky. This AFFECTS man as the body tries to cool off in a harder way by increasing rate of respiration and depth of blood circulation.
