Answer:
The researchers add a compound to the cell growth medium that both binds and releases protons (H+) and also pass through lipid membranes. The effect that the added compound will have on the ATP production by the cells is that ATP synthase will stop.
Answer:
Hilda and her family are going on a sailing trip this summer, and Hilda is especially interested in spotting dolphins. In which zone of the ocean is Hilda most likely to spot dolphins? Hilda and her family are most likely to spot dolphins in the PELAGIC zone. To view shorebirds and crabs, Hilda should move towards the INTERTIDAL zone.
Explanation:
The Pelagic Zone
It is any water in an ocean or lake that can not be said to be positioned in proximity to the shore or in proximity to the bottom (the shore and the bottom are two distinct zones with a completely different properties.
Divisions of the Pelagic Zone
It can be grouped into subzones based on depth, we have the epipelagic, close to the top of the zone which as light been present, and the abyssopelagic, is nearer to the bottom with light being absent.
The intertidal zone
Its found between the high tide (upper limit) and low tide lines (lower limit), majorly on the beach at the water's edge.
The major attribute of the intertidal zone is that it is immersed with water at high tide and is in exposure to the air at lower limit. The intertidal zone is usually undergoing alterations leading to organisms that are uniquely adapted to strive there.
Organisms found in this zone are sea stars, crabs, mussels, barnacles, and various corals as they well situated to strive immersed in water and a region of their lives open air at lower limit.
Answer:
Option D
Explanation:
Cyanobacteria preserve its photosynthetic pigments in the thylakoids which allows masking of green of chlorophyll a and other accessory pigment i.e phycobiliproteins (phycocyanin, allophycocyanin and phycoerythrin).
Chlorophyll a is mainly responsible for harvesting light for photosynthesis. Phycocyanin is blue in color, allophycocyanin is blue in color and phycoerythrine is red in color. These together harvest light in the green, yellow and orange part of the spectrum which cannot be used by other phytoplankton species
Hence, option D is correct
Answer:
The correct answer would be Both types of fingerprints can often be easy to obtain from the crime scene.
DNA fingerprinting is a technique used for a paternity test and in establishing a link between the biological evidence and suspect in the crime, identification of dead bodies et cetera.
It is based on the similarities and differences associated with the DNA sequence of organisms especially the non-coding or junk DNA.
The DNA fingerprints are developed in labs, they are not found at crime scenes.
At the crime scene, pieces of biological evidence such as blood, skin, hair et cetera are taken from which DNA could be extracted.
1. Nucleic acids are the molecules that code the genetic information of organisms.
2. The two nucleic acids used in the repair, reproduction and protein synthesis are deoxyribonucleic acid (DNA, shown) and ribonucleic acid (RNA)
3. DNA and RNA are polymers made up of monomers called nucleotides
