CaHeK987 [17]

Answer:

The activity of speed up the process.

Explanation:

Reverse transcriptase is an enzyme encoded from the genetic material of retroviruses that accelerate or speed up the process of  transcription of retrovirus ribonucleic acid into deoxyribonucleic acid. Reverse transcriptase enzyme is also called RNA-directed DNA polymerase. Some retroviruses such as human immunodeficiency virus (HIV) and avian myeloblastosis virus used this Reverse transcriptase enzyme.

Several fish species became extinct millions of years ago. The graphs provided below show the distribution of fossils of these f
cestrela7 [59]
1. Explain why the distribution of fossils in Figure 1 supports the hypothesis that the extinction of these species was the result of a sudden environmental change.
This hypothesis can be supported because all the fossils accumulate almost at the same age of the rock layer. That is, all the fossils died almost at the same time.

2. Describe an environmental change that could have produced this type of fossil distribution.
Good examples of sudden environmental changes are volcanoes. When a rash occurs, the whole environment suddenly changes for different reasons such as ash or lava, and all living things can die immediately or in a few years by the change in the ecosystem.

3. Explain why the distribution of fossils in Figure 2 supports the hypothesis that the extinction of these species was the result of a gradual environmental change.
This is because the fossils accumulate at different ages of the rock layer, that means, the species dying over time. The gradual descent of the fossils is observed.

4. Describe an environmental change that could produce this type of fossil distribution.
For example, if a climate change occurs - the temperature increases or decreases - it can cause the trees or plants to die and all the animals in the ecosystem also die when they have no food. But this process is sequential, so the change can take years, centuries or even millions of years.

I hope this can help you.

Which of the following is/are common to chemiosmosis and the light-dependent reactions of photosynthesis? electron transport onl
blondinia [14]

Answer:

Both electron transport and a proton gradient

Explanation:

The process of oxidative phosphorylation in mitochondria and electron transport chain in photosynthesis undergo chemiosmosis to produce ATP molecules.

Chemiosmosis is a process where the energy utilized by the movement of proton and electrons produces ATP molecules.

Both the processes involve the movement of electrons through electron carriers where the reduced energy is utilized to drive the flow of protons through the plasma membrane. This creates a proton gradient across the plasma membrane which rotates the ATP synthase and converts the ADP molecules into ATP molecules.

Thus, the selected option is correct.
