1. Which statement is correct regarding the cells and DNA?
a. All the cells have identical DNA
b. The DNA of the fertilized egg differs from the DNA of all of the other cells
C. The DNA of the fertilized egg differs from some, but not all, of the other cells
d. Only the fertilized egg contains DNA.
DNA stands for deoxyribonucleic acid. It carries all the genetic information of an individual. All the cells have identical DNA.
What is the role of DNA?DNA has an important role in processing genetic information. It is responsible for the transmission of characters from one generation to other.
DNA is a double helical structure that has two strands running opposite each other in an antiparallel direction. It gives DNA a ladder-like appearance.
All cells have DNA and are identical.
Thus, the correct option is a.

Compare and contrast (three differences and three similarities) between density-independent and density-dependent limiting factor. (8th grade level)
Answer:
The correct answer is - similarities and differences are as follows:
Explanation:
Similarity 1: density-independent and density-dependent factors can limit population growth
Similarity 2: density-independent and density-dependent factors are abiotic and biotic factors
Similarity 3: both are affected by the factors that affect the birth rate and death rate. competition and predation are the density-dependent factors that affect the birth and death rates and severe weather and conditions such as fire are factors that change the rate of death and birth in the population.
The differences are as follows:
Difference 1:
Density-dependent limiting factors - results in a change of carrying capacity of the population whereas density-independent limiting factors - results in a change of both logistic and exponential growth of the population
Difference 2:
Density-independent factors take place due to overgrowth and density-dependent factors do not result due to the change in the population size and occurs randomly.

1. Binary fission is observed in (a) Hydra (b) yeast (c) Amoeba (d) human being
Answer:
Amoeba
Explanation:
Binary fission is a type of asexual reproduction in which a cell divides to form two cells. It occurs in organisms that are protozoans. This means that two new daughter cells are formed in the process.
During the process of binary fission, the cell Is divided into two, this means that the DNA is replicated in both parts so that each of these cells becomes an independent organism, this means that they would be able to survive and function on their own.
Hence from the options listed, binary fission is observed in Amoeba
