The different chromosomal combinations would be calculated using the formula;
2^n; where n is the number of different chromosomes. \
Using this formula ; when the diploid number is 14 (for 7 pairs ) will be given by; 2^7 = 128 different combinations.
It means that a barley plant which has seven pairs of chromosomes will have 128 different combinations.
Answer:
The correct options are A,C and E.
Explanation:
In geology, plateaus can be described as uplifted areas that are generally flat from the upper surface. The formation of plateaus takes millions of years. They are also called as tablelands due to their structure.
A plateau might form when the magma inside the Earth cooled and is raised above the surface of the Earth's crust. It can also be caused due to an erosion of a mountain generating lava.
Answer:
organisms are very numerous and diverse
Intrapleural pressures must remain negative to prevent lung collapse.
<u>Explanation:</u>
The intrapleural pressure is the taking place within the cavity of pleural, whose pressure is marginally lower than the atmospheric pressure in what is understood as a negative pressure. The intrapleural pressure is equivalent to or exceeding the atmospheric pressure if the plural cavity is impacted, thus pneumothorax increasing occur.
This negative pressure is at resting mode and brings us a lung-expanding transpulmonary sensation. Put an easier way, if even when exhaling we didn't sustain a mildly negative pressure, our lungs would collapse on themselves as all the air would stream into the lower pressure area. The pressure intrapleural is subatmospheric, which is related to the lungs and chest recoil apart from each of the other.
The interaction between red-billed oxpecker and impala is mutualism. The interaction between titan triggerfish and smaller fishes is commensalism.
<h3>Mutualism and Commensalism</h3>
Mutualism is a form of symbiotic interaction between two organisms in which both organisms benefit from the interaction without being negatively affected in any way.
Commensalism, on the other hand, is a form of interaction between two organisms in which one (the commensal) gains and the other neither benefits nor lose from the interaction.
The red-billed oxpecker gets its food off the fur of the Impala. The tick that serves as food for red-billed oxpecker is a parasite that harms the impala. Thus, the red-billed oxpecker gets its food while the impala gets the ticks that can harm it removed. A mutually beneficial relationship.
The activities of the Titan triggerfish benefit smaller fishes. The Titan triggerfish neither benefits nor gets harmed in the interaction. A form of commensalism.
