Intraspecific competition can be described as an interaction between organisms of the same species in which they compete for resources like food, water, shelter etc.

In contrast, interspecific interactions are they type of interactions which occur in different species. For example, a fox and a lion and fighting for the same prey.

Explain how gene expression is more complicated than it looks.

Answers

A cell typically expresses only a fraction of its genes, and the different types of cells in multicellular organisms arise because different sets of genes are expressed. Moreover, cells can change the pattern of genes they express in response to changes in their environment, such as signals from other cells. Genes can't control an organism on their own; rather, they must interact with and respond to the organism's environment. Some genes are constitutive, or always "on," regardless of environmental conditions. Such genes are among the most important elements of a cell's genome, and they control the ability of DNA to replicate, express itself, and repair itself. These genes also control protein synthesis and much of an organism's central metabolism.

Name the two stages of respiration that are aerobic

Answers

Aerobic cellular respiration uses oxygen and yields many more ATP molecules than anaerobic cellular respiration, which does not use oxygen and yields only two ATP molecules. There are three stages in the process of transforming glucose to ATP: glycolysis, the citric acid cycle, and the electron transport chain.
