Answer:
Chlorophyll's job is to obsorb sunlight into the plant to be able to use the process of photosynthesis! Answer is C
The answer is purple and smooth.
It is known that the in dihybrid cross (a cross between two
different traits), the phenotypic ratio between the offspring of two heterozygous parents in the F2
generation is 9:3:3:1.
<span>purple and smooth = 75 (</span><span>≈ 9 </span><span>· 8)</span>
<span>white and smooth = 28 (</span><span>≈ 3 </span><span>· 8)</span>
<span>purple and wrinkled = 24 (= 3 </span><span>· 8)</span>
<span>white and wrinkled = 8 (= 1 </span><span>· 8)</span>
<span>
</span>
So, the ratio between the offspring is close to 9:3:3:1 in F2 generation.
This means, that the only heterozygotes are present in the F1 generation, and they must be purple and smooth.
Answer:
B
Explanation:
It has membrane-bound organelles. Mitochondria and chloroplasts are structures found in the eukaryotic cells.
Answer: Reptiles include snakes, turtles and lizards, while amphibians include toads, frogs and salamanders. One difference between reptiles and amphibians is their relationship with water.
Explanation:
Amphibians:
- Skin is smooth and highly porous.
- The webbed feet help them to swim.
- Their eggs are covered with gel.
Reptiles:
- Skin is dry, hard and scaly.
- They have limbs to facilitate running and swimming.
- Their eggs are covered with a hard protective covering.
Answer:
B, E are true
Explanation:
The process of respiration produces energy for organisms by combining glucose with oxygen from the air. During cellular respiration, glucose and oxygen are changed into energy and carbon dioxide. Therefore, carbon dioxide is released into the atmosphere during the process of cellular respiration.
A is false because respiration also happens in plants and is best at night (light not present)
B is true because during the reaction co2 is produced as waste
C is false because co2 is a waste product not a reactant
D is fals because o2 is a reactant not a product
E is true because the whole point of respiration to to produce energy (ATP)
F is false because this occurs in plants aswell
