Im pretty sure its cell, species, biosphere. Hope i can help :)
The mode of nutrition of animal-like protist are holozoic or parasitic. Holozoic mode is a method of nutrition that involves the intake of liquid or solid organic material and utilizing it. Parasitic, on the other hand, involves the an organism feeding on a host organism.
The different DNA sequence for a gene shows that same character can be expressed in 2 or more forms. Alleles are present on homologous chromosome.
Explanation:
The gene is the DNA sequences on the chromosome coding for the particular trait in an organism.
The alleles are the variant of the gene. In a homologous chromosome the variant of the gene or allele is present. The homologous chromosome is present in progeny one from each parent.
For example the allele for tall as homozygous is present on one of the parent and shortness on the other parent in homologous chromosome. The trait of height is the gene and the way it expresses itself is the trait from either parent. The DNA sequence will also be different for the alleles because they will code for different proteins like short or tall phenotype.
The genotype will be different hence DNA sequence is also changed.
Connective tissue: holds the heart in place while the body moves
muscle and nervous tissue: pump the heart
epithelial tissue: protects the heart from the damage other parts can do
