Answer:
(-) sense single-stranded RNA
Explanation:
Negative sense refers to viruses that use the negative sense single stranded RNA as their genetic material.
It is essential for the negative viral strand is complimentary to the mRNA so it is converted to a positive RNA by RNA polymerase.
Negative sense single stranded RNA virus require an RNA dependent RNA polymerase for transcription. This is because it essential in encoding proteins by catalyzing the complimentary RNA strand to the given RNA tempelate.
<span>The structure of the feet and legs varies greatly among frog species, depending in part on whether they live primarily on the ground, in water, in trees or in burrows. Frogs must be able to move quickly through their environment to catch prey and escape predators, and numerous adaptations help them to do so. Most frogs are either proficient at jumping or are descended from ancestors that were, with much of the musculoskeletal morphology modified for this purpose. The tibia, fibula, and tarsals have been fused into a single, strong bone, as have the radius and ulna in the fore limbs (which must absorb the impact on landing). The metatarsals have become elongated to add to the leg length and allow the frog to push against the ground for a longer period on take-off. The illium has elongated and formed a mobile joint with the sacrum which, in specialist jumpers such as ranids and hylids, functions as an additional limb joint to further power the leaps. The tail vertebrae have fused into a urostyle which is retracted inside the pelvis. This enables the force to be transferred from the legs to the body during a leap </span>
<span>The muscular system has been similarly modified. The hind limbs of ancestral frogs presumably contained pairs of muscles which would act in opposition (one muscle to flex the knee, a different muscle to extend it), as is seen in most other limbed animals. However, in modern frogs, almost all muscles have been modified to contribute to the action of jumping, with only a few small muscles remaining to bring the limb back to the starting position and maintain posture. The muscles have also been greatly enlarged, with the main leg muscles accounting for over 17% of the total mass of the frog.</span>
Answer:
Resistance = 30 Ω
Explanation:
The resistance of an electric circuit =
voltage = 24V
current (I) = 0.80A
Therefore, R =
R = 30 ohms
<span>The ocean affects the earth’s climate by utilizing the sun’s
energy. Based on the amount of the Sun’s
energy that is absorbed by the ocean, multiple things can happen. For example in
California, the sun heats the Pacific Ocean which heats the winds, which brings
the warm climate to the state. Also, the ocean’s play a major role in the water
cycle. The amount of precipitation falling on an area can affect its weather
and climate. hope this helps!!!! </span>
Heterotrophs eat Autotrophs & depend on them for their energy supply
Hope this helps!
