Hills go up and back down again. Plateaus go up and stay at a maximum level. For example, If you were measuring the elevation of certain points on a hill, it would look something like (in units): (1, 2, 3, 4, 5, 6, 6, 5, 4, 3, 2, 1). If you were measuring the elevation of certain points on a plateau, it would look something like (in units): (1, 2, 3, 4, 5, 6, 6, 6, 6, 6, 6, 6, 6).
Species Diversity is a number of different species
The correct answer is 'If molecules are small enough, then they can pass through the semipermeable membrane because they can cross the semipermeable membrane from their small pores or openings'.
The semipermeable membrane is permeable to few molecules, and the smaller molecules pass through the molecules from small pores present in the semipermeable membrane. The size of the big molecules are large, so, they cannot cross through semipermeable membrane.
Answer:
The correct answer is : Overconfidence.
Explanation:
A person who thinks his or her sense of direction or judgement is more accurate than it is actually is is known as overconfident, and this phenomenon is known as the overconfidence.
In this case, Jonah and Cathy attempted most of the question of the exam and secured less than 60% on the exam which suggests they have less knowledge than they thought they know, it is a sign of overconfidence.
Thus, the correct answer is overconfidence.
Answer:
Among others, two adaptations might be
- Avoiding corporal heat loss
- Increasing oxygen absorption
Explanation:
Up in the mountains, there is low oxygen, food is scarce, and adverse meteorological conditions. Animals and plants need to develop different strategies to survive. These adaptations involve not only physical and physiological changes but also behavioral changes. To mention a few adaptations, we can name:
- Avoiding heat loss. Temperature tends to be very low at highs, so, to <u>avoid heat loss,</u> animals develop shorter legs, tails, and ears. By doing this they reduce the area or surface of heat loss and also avoid getting frozen. In mammals, the coat is also very important. A thick coat helps them maintain a constant body temperature and keep warm. Some amphibians might also develop a thicker skin as they can not regulate their temperature, and it also helps them not to dehydrate.
- Camouflage: Coat is also helpful in camouflaging. Mammals´ hair color depends on their environment. Some animals, such as hares, can also change their fur color depending on the season. During snow seasons they turn white, and during the warmer season, they turn yellow or brown.
- Size and metabolism: Small mammals lose heat very fast, so they need to keep active and feeding most of the time. They have an elevated metabolism to keep warm. On the contrary, big animals, such as bears, need to hibernate to reduce their metabolism and get to survive, otherwise, they would need many reserves to cover their energetic requirements.
- Oxygen absorption: Some animals have adapted to the lack of oxygen by increasing their heart and lungs capacity as well as their capability to absorbing more oxygen from the blood.
