Answer:
Due to different pigments.
Explanation:
The multicellular algae are red, green and brown because of the presence of pigments. The red algae are red in colour because of the presence of the phycoerythrin which is a type of pigment. This pigment reflects red light due to already presence in its body and absorbs blue light that is necessary for photosynthesis process. The brown algae contain fucoxanthin pigment and green algae contain xanthophylls pigments that are responsible for its colour so we can conclude that these different types of pigments are responsible for the different colour of algae.
It shows up in your stool. Specifically the undigested food includes material that cannot be absorbed by the vili found in the small intestine. Thereafter the material moves to the large intestine, goes through the bowel tract, turns into feces and exits the GI tract via the rectal cavity
Answer:
a. Biomagnification
Explanation:
Biomagnification is the name given to the progressive accumulation of substances from one trophic level to another along a food chain. Thus, the substance will have its highest concentration in individuals who occupy trophic levels furthest from producers.
For biomagnification to occur, substances must be fat soluble (lipid soluble) and thus adhere to living tissues. Another feature of substances that undergo biomagnification is that they are generally not biodegradable or metabolized by the body.
The phenomenon is quite common with heavy metals (lead; mercury) and certain chlorinated and aromatic organic compounds with higher molecular mass, such as the insecticide DDT.
Answer: Mitochondria
Explanation:
The Mitochondria.
The mitochondria produces energy for the cell to use by converting chemical energy from food into a form of energy in which is usable to the host cell through a process of oxidative phosphorylation
Although DNA is mainly packaged within chromosones confined in the nucleus, mitochondria also has a small quantity of unique DNA found within them called mitochondrial DNA. DNA found within the mitochondria differs from DNA found within the nucleus in the sense that it can self replicate.
Energy is released from ATP by the breaking of the phosphate bond. A<span>denosine triphosphate, or ATP, consists of a sugar called ribose, the molecule adenine and three phosphate groups. During the hydrolysis of ATP, the last phosphate group is transferred to another molecule, thus breaking the phosphate bond. This reaction causes energy to be released to power other activities within the cell.</span>
