Answer:
Intraspecific competition is when organisms within the same species compete for resources. <u>Interspecific competition is when competition for resources happens between different species of organisms.</u>
Answer: Neurogenic Shock
Explanation:
The main function of brain is to control and communicate with the body and controls the normal functioning of the body.
The brain sends signals to the various parts of the body for the proper movement and coordination.
This occurs by the help of neurons and if there is any interruption in the coordination between body and brain then it can be termed as neurogenic shock.
Chloroplast and cyanobacteria are thought to be related as it is the only eukaryotic algae having chloroplast because they synthesise food by photosynthesis
Answer: the development of the enzyme Rubisco and evolution of oxygenic photosynthesis.
Explanation: One can pick many key steps in early evolution: the development of the first cells, oxygenic photosynthesis, endosymbiosis leading to eukaryote organisms.
One important step was the mutation to the enzyme ribulose bisphospate carboxylase oxygenase (Rubisco) which enabled oxygenic photosynthesis.
The cyanobacteria that had Rubisco changed the planet’s atmosphere by producing oxygen as a by-product of photosynthesis. They were the most successful organisms of the time and have continued as a successful and ubiquitous group of organisms for billions of years.
The production of oxygen changed the direction of evolution profoundly. Later endosymbiosis led to the evolution of plants, with cyanobacteria the ancestors of chloroplasts, making Rubisco one of the most common enzymes on the planet.
These are called evaporites!
