Answer:
sea water contains a salt
Biologists who work in the fields of genomics and molecular biology study DNA genome content and analyze genetics on a molecular level. They do it to map DNA and use it to prevent diseases or anything similar.
Answer: A. In the electron transport chain, a series of reactions move electrons through carriers.
B. The products of the electron transport chain are H2O and either NAD or FAD.
E. The electron transport chain is a series of oxidation-reduction reactions that occur in the inner mitochondrial membrane.
Explanation:
the best suitable statement is it transfers energy stepwise from one compound to another, The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria. Electrons are transferred from one member of the transport chain to another in a series of redox reactions.
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made up of protein and a single molecule of deoxyribonucleic acid (DNA).
The unique structure of chromosomes keeps DNA tightly wrapped around spool- like proteins, called histones. Without this kind of packaging, DNA molecules would be too long to fit inside the cells.
DNA molecules in a single human cell if unwound from their histones and placed end to end, they would measure 6 feet in length.
Chromosomes play a key part in ensuring that DNA is accurately copied and distributed to new daughter cells as the parent cell divides to form new cells.
Answer:
The five types of interactions between species are
1) Competition: In such a type of interaction, organisms interact by competing for resources such as water, food resources, shelter etc.
2) Predation: In such a type of interaction, organisms of a species known as predators feed on organisms of the other species known as prey. For example, a lion feeding on a deer.
3) Commensalism: In such a type of interaction, an organism of a species benefits from the other organisms and the other organisms neither gains benefit nor loss. For example, Tree frogs using plants for protecting themselves from predators.
4) Mutualism: In this type of interaction, both the organisms of different species gain benefit from each other. For example, insects carry pollen when they move from one plant to another and in turn they use plant as a source of food.
5) Parasitism: It is a type of interaction in which one organism benefits whereas the other one is harmed. For example, Malaria is caused by anopheles mosquito feeding on the blood of humans.
