The answer is C) 9:3:3:1
This looks like a dihybrid cross where the expected phenotypic ratio is 9:3:3:1. However, in nature, the numbers cannot be absolut. Let's check it out:
242 purple wrinkled
84 purple smooth
70 yellow wrinkled
24 yellow smooth
Divide all by the smallest number:
242 purple wrinkled / 24
84 purple smooth / 24
70 yellow wrinkled / 24
24 yellow smooth / 24
We have
10.1 purple wrinkled which is near to 9
3.5 purple smooth which is near to 3
2.9 yellow wrinkled which is near to 3
1 yellow smooth
Plants can make their own food by photosynthesising however, animals need to consume plants for energy/as food if their were no plants animals would starve. plants also provideanimals with oxygen as a waste product of photosynthesis which animals need to survive
An ecosystem is the biotic and abiotic factors which are responsible for the survival of an animal
Air passes through is: Nostrils → nasal cavity →Pharynx → Larynx →Trachea → Bronchi (with cartilaginous rings) →Bronchioles (without rings) → Alveoli (air sacs). Alveoli are the seat of exchange of O2 / CO2 between lungs and blood.
Answer:
The incorrect statement is -C. They are ALL parasites that harm their host by living in or on it.
Explanation:
Protists are organism shows the vast difference and have a single cell microscopic eukaryotic cell. These are based on their characteristics similar to plants or animals divide them into two groups called plant-like protists and animal-like protists.
Animal-like protists are also a eukaryotic unicellular organism that depends on other organisms for their food so they are called heterotrophs. Some of these organisms also parasites and affect their host negatively. These are also organisms that are live symbiosis and help other organisms.
