Answer:
4
Explanation:
The correct answer would be <u>hydrotropism</u> and <u>thigmotropism</u>.
Hydrotropism is defined as the movement of a plant or its organs to or away from moisture. The deep root growth of plants is a way of seeking or growing towards moisture that is present deep in the soil. Hence, <u>the root is said to exhibit positive hydrotropism.</u>
Thigmotropism, on the other hand, is the growth or movement of plants or their organs to or away from touches. In this case, <u>the tendrils of the plant that wraps around objects they come in contact with are showing positive thigmotropism.</u>
The correct option is, therefore, option 4.
Let's start with "human." True. The earliest fossils we have of human are recognizably our species, but do not belong to any extant racial type.
Since humans are an extant species, that would make "modern" also true.
Arguably, human fossils that are 195,000 years old would be "ancient" which would make "ancient" true too.

Answer:
a.)It will rise faster in cooler air
a.) heat
Explanation:
i
A hot air balloon rises faster if cold air were to surround it due to density differences between the air in the two medium.
- Hot air is less dense as the average kinetic energy of the molecules is greater.
- Cold air is denser.
- This density contrast causes the balloon to move up at a high pressure.
ii. Heat
The average kinetic energy of the molecules in a substance is termed heat.
Heat is a form of thermal energy measured by the kinetic energy possessed by molecules in a substance.
Answer:
The front term is associated with an area where two air masses met and as it is usually the condition with heavy rain, fierce wind, snow and other violent weather like a war situation. The front could be warm, cold, occluded or stationary depends on the type of weather.
The cold front is associated with lots of thunderstorms and other intense weather while the warm front changes with drizzly rain and warmer weather due to the fact that in a cold front, replacement of warm air by the cold air is faster while in a warm front, the replacement of cold air by warm air is gradual
