Explanation:
A Recessive trait is the situation in which a trait is expressed, this occurs when an organism has two recessive alleles.
The answer is A because cells take in glucose and oxygen and make energy, with the waste products of CO2 and H2O
Answer:
make up genes and chromosomes
Explanation:
Darwin is known for his theory of evolution which explained how the organism evolved on the planet and the Mendel is known for his explanation that how the traits are passed on to the generation.
But both were unaware of this that the factors which control the traits are composed of DNA.
The DNA was discovered in 1869 in the nucleus of the white blood cells but it was not established that the genetic material is the DNA as it was discovered later in 1944. The later studies on the DNA showed that the DNA forms the genes which control the trait and are present on the chromosomes.
Thus, makeup genes and chromosomes is correct.
The plant cells are more complex because it has more structures like the cell wall and chloroplast.
Plant cells can be larger than animal cells. The normal range for an animal cell varies from 10 to 30 micrometers while that for a plant cell stretches from 10 to 100 micrometers. Beyond size, the main structural differences between plant and animal cells lie in a few additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles.
Hope this helps.
