Answer:

a. ATP and NADPH

Explanation:

Light-dependent reactions of photosynthesis include splitting of water in the presence of sunlight and release of electrons. The electrons move from the reaction center of the PS-II via electron carriers to the PS-I. From the reaction center of PS-I, the electrons finally reach NADP reductase and reduce NADP into NADPH.

During this electron transfer via electron carriers, a proton concentration gradient is generated across the thylakoid membrane. The energy of this gradient is used to drive ATP synthesis. ATP and NADPH formed during the light-dependent phase of photosynthesis are then used during the reactions of the Calvin cycle.

A population of salamanders lives near a stream. A severe drought dries up the flow of the stream. What is this effect on the sa
sertanlavr [38]

Answer:

limiting factor

Explanation:

In an ecosystem, certain factors hinder the growth or abundance of the population of organisms. These factors are called LIMITING FACTORS. Limiting factors, which can be biotic, food, drought, predation, disease etc, are factors that inhibits a population of organism from becoming enlarged. There are two types of limiting factors viz: density dependent (depends on size) and density independent (not dependent on size).

This is the case of a drought that dries up the stream that inhabits a population of salamanders. The drought causes the unavailability of water, which will ultimately have an effect on the growth of the salamander population. Hence, the DROUGHT is considered a LIMITING FACTOR.

maxonik [38]

Those changes in an individuals' genotype that ensure genetic variation begin to be done in Metaphase, where chromosomes are aligned to the equatorial axis of the cell, and eventually, each chromosome is pulled to each pole of the cell during Anaphase I. After this process, follows telophase I, where we can say that each chromosome is given to each of the two daughter cells. We can say then that the creation of different versions of alleles begins with Telophase I.

Which is a step of the scientific method in environmental science? A. Testing a hypothesis B.Carrying out research C.Collecting
atroni [7]

Answer:

The correct answer is Option B (Carrying out research). The step that follows this step involves forming B.a conclusion

Explanation:

The Natural environment  around us is a function of both the living things and the non-living things. So, environmental science is the study of the natural environment around us. This study includes how to tackle environmental problems and further study on how humans could be impacted by the interactions with their environment. The scientific method is a step taken towards ensuring development in a field by bringing new discoveries and challenging existing beliefs through scientific tests and research. Generally, for most scientific methods of many fields, it starts with:

1. Observations

2. Making inquiry which involves asking questions

3. Forming a hypothesis, which means making untested assumptions

4. Conducting an experiment to check the hypothesis

5. Analyze the results

6. Publish the results

The correct answer is Option B (Carrying out research). Because it involves the scientific method highlighted above. The step that follows this step involves forming B.a conclusion
