Answer:
a. an example of a transgenic tomato (also called GMO tomato)
Explanation:
Genetic modification is the process by which an organim's genome is manipulated in order to achieve a desirable feature in such organism. Also called genetic engineering, genetic modification involves using biotechnology to alter an organims genetic composition. The organism whose genome is manipulated is called GENETICALLY MODIFIED ORGANISM (GMO) or TRANSGENIC ORGANISM.
In this case, a tomato with a gene from a fish that helps the tomato resist frost damage is said to be an example of GMO or transgenic organism because the genome of the tomato plant has been manipulated by inserting a desirable gene (resistance to frost) into it.
<span>Mitochondrion a singular word for mitochondria is a "powerhouse" organelle of the cell. </span>
<span>Mitochondrion is an important organelle in most living organisms because it is where biochemical processes of living organisms such as respiration takes place. The mitochondrion has a smooth outer membrane but a larger inner membrane. The inner membrane is about 70% protein and is very convoluted because that can even fit inside the outer membrane. Mitochondrion is the carrier of the Kreb's cycle in the matrix and it is responsible for the transfer of electron chain found in the cristae of the inner membrane.</span>
Answer:
C. Scavenging of dead animals and gathering of plants (just as Homo <em>habilis</em> had done), and perhaps the hunting of smaller animals
Explanation:
Homo <em>erectus</em> (erect man): Homo erectus is believed to be appeared about 1.5 million years ago. It was in the middle Pleistocene age when they evolved from homo habilis. Homo erectus probably ate meat, was around 1.5-1.8 meters tall and males were probably larger than females. As the name suggests they has erect posture. His skull was flatter than that of modern man and he had protruding jaws. Other features includes projecting brow ridges, small canines and large molar teeth. Their cranial capacity was 900 cc. Cranium was dome shaped to accommodate the large brain. Homo erectus was omnivorous and he made various tools using stones and bones. He made use of fire for hunting, defense and cooking. Homo erectus inculdes three fossils: Java Ape-man, Peking man and Heidelberg man.
Answer:
Humans lack DNA in their brain cells.
Explanation:
Answer: Density dependent
Explanation: It is a density dependent because there has is a direct correlation between the ratio of predatory animals to prey animals for an ecosystem to function properly. Otherwise the ecosystem begins to die.
