Answer:
response to stimuli / tropism
Explanation:
The plants and animals always respond to stimuli. It is an innate character of all living things. When a bright light falls on the eye, it closes immediately. This is responding to the stimuli. When someone touches the leaves of touch-me-not plants it closes its leaves due to the external stimuli.
The plants respond to the light. Because it does photosynthesis in the presence of light. Therefore, the leaves and branches of the plants always bend towards the light. This process is called phototropism.
Similarly, the roots of the plants move towards gravity under the ground. This is called geotropism.
Besides phototropism and geotropism, other types of stimuli are there - hydrotropism(response to the water), chemotropism(response to certain chemicals).
That's why the plants growing on the windowsill move towards outside where light comes.
Answer:
In conditions of low or no oxygen the process of anaerobic respiration occurs. The 'an' in 'anaerobic' means without. During anaerobic respiration, the oxidation of glucose is incomplete - not all of the energy can be released from the glucose molecule as it is only partially broken down.
Explanation:
DNA
1. Found in nucleus
2. Sugar is deoxyribose
3. Bases are A, T, C, and G
RNA
1. Found in nucleus and cytoplasm
2. Sugar is ribose
3. Bases are A, U, C, and G
Anaerobic means with out oxygen
Answer:
Tt Rr WW
Explanation:
Given:
1. tall (T) is dominant to short (t)
2. red flowers (R) is dominant to white flowers (r)
3. wide leaves (W) is dominant to narrow leaves (w)
4. Also, a tall, red, wide-leaved plant is crossed to a short, white, narrow-leaved plant
To find: genotype (with correct arrangement of alleles) of a tall, red, wide-leaved parent
Solution:
Genotype (with correct arrangement of alleles) of a tall, red, wide-leaved parent is Tt Rr WW
