Answer:
The correct answer is - A. phototropic and gravitropic.
Explanation:
A plant seedling grows usually two-direction shoots or stems towards light and roots towards the soil or in the direction of gravity. The movement of the plant toward a specific stimulus or effect parts is called tropism and different parts move in a different direction.
The movement of the roots of the plant is usually towards the direction of soil or gravity and this is called gravitropic. The shoot or stem grows from the seedling towards the direction of light and it is called phototropic.
Answer:
A stream channel is the physical confine of a stream consisting of a bed and stream banks. Stream channel development is controlled by both the water and sediment movement.
Deforestation leads to fewer plants being available to conduct photosynthesis. Less oxygen is available for cellular respiration is a possible effect on the remaining plant populations.
<u>Explanation:</u>
- Deforestation and Photosynthesis are related to each other. Because if Deforestation occurs more photosynthesis will reduce.
- Cutting and burning down of the trees causes deforestation as it affects photosynthesis. Plants prepare food using photosynthesis.
- The plant takes carbon-di-oxide for the preparation of food and releases oxygen. Oxygen is required for every living thing in the world.
- As now World goes on deforestation and it should be seriously stopped.
Thorndike's law of effect is described below.
Explanation:
- Operant Conditioning. A form of associative learning in which the consequences of a behavior change the probability of the behavior's occurance. According to Thorndike's Law of Effect. Behaviors followed by bad results are less likely to occur and behaviors followed by good results are more likely to occur again.
- The law of effect is a psychology principle advanced by Edward Thorndike in 1898 on the matter of behavioral conditioning (not then formulated as such) which states that "responses that produce a satisfying effect in a particular situation become more likely to occur again in that situation, and responses that produce
- Thorndike's Law of Effect states that a response followed by a pleasant consequence is more likely to be repeated, whereas a response followed by an unpleasant consequence is more likely to be diminished. ... This special stimulus has the effect of increasing the behavior occurring just before the reinforcer.
- Law of effect. Law of Effect. The law of effect states that if a response in the presence of a stimulus is followed by a satisfying event, the association between the stimulus and the response is strengthened.
18% because C pairs with G. A pairs with T. T and C are not complementary base pairs, but we do know that if a molecule consists of 32% T, it must have 32% A as well.
32 + 32 = 64
100 - 64 = 36
36 ÷ 2 = 18
There must be 18% of C.
