D) where water covers the land
<span>Air pollution is the presence of harmful substances in the earths atmosphere </span>
<u>Answer:</u>
Organisms C and D are more closely related than
Organisms A and B
<u>Explanation:</u>
Organisms A and B are not related much as the distance between them is more than the organisms C and D so the C and D are closer than A and B. The phylogenetic tree shows the biological evolutionary relationship among various biological species. So the given tree shows the relationship as mentioned above.
It also show the physical and genetic relationship among the various biological species. The phylogeny is generally shown by using a particular phylogenetic tree. For example, the simple one below which describes the different evolutionary relationships between the great apes. The genus Pongo includes orangutans, Pan includes chimpanzees and bonobos, and Homo includes humans, while Gorilla is self-evident.
Answer:
The correct answer is cell organelles.
Explanation:
A unique membrane-bound composition, which is found inside the eukaryotic cell's cytoplasm, that is, in plants and animal cells is termed as cell organelle. Some of the examples of cell organelles found within the cells of eukaryotes are endoplasmic reticulum, Golgi complex, mitochondria, chloroplast, etc.
All these organelles play an essential function for the proper functioning of the cell, like chloroplasts found in plants play an essential role in the process of photosynthesis, and mitochondria both in plants and animals are regarded as the powerhouse of the cell.
Answer:
Chromosomal Mutation
Explanation:
The development and function of an organism is in large part controlled by genes. Mutations can lead to changes in the structure of an encoded protein or to a decrease or complete loss in its expression. Because a change in the DNA sequence affects all copies of the encoded protein, mutations can be particularly damaging to a cell or organism. In contrast, any alterations in the sequences of RNA or protein molecules that occur during their synthesis are less serious because many copies of each RNA and protein are synthesized.
Geneticists often distinguish between the genotype and phenotype of an organism. Strictly speaking, the entire set of genes carried by an individual is its genotype, whereas the function and physical appearance of an individual is referred to as its phenotype. However, the two terms commonly are used in a more restricted sense: genotype usually denotes whether an individual carries mutations in a single gene (or a small number of genes), and phenotype denotes the physical and functional consequences of that genotype.
