Answer:
<u>B) decreased rates of photosynthesis</u>
Explanation:
Plants, phytoplankton, algae, and other microorganisms photosynthesize using energy in the form of solar radiation. Photosynthesis is a chemical process that's integral to these organisms, which are called producers.
They combine light energy from solar water and carbon dioxide, in a complex process that produces chemical energy in the form of glucose.
Photosynthesis is a rate-limited reaction; it depends on various factors including carbon dioxide availability and light intensity. When light is limited, the rate of photosynthesis decreases due to its slowing effect on the light-dependent reaction in photosynthesis, occurring in the chlorophyll.
Answer: cellular report occurs in the respiratory system or the lungs and nasal cavity
explanation: it happens because when we intake oxygen, it reacts with glucose present in our body. this reaction gives out carbon dioxide, water and energy as products.

I think your answer is
They dvelop from 2 separate eggs
Fraternal twins each come from their own egg and sperm. The term for this is dizygotic , while identical twins are monozygotic.
Explanation:
hope this helps
A is hypertonic so water is leaving the cell going into the solution, the cell shrinks. B is isotonic so there is no net transfer of water. C is hypotonic so water is entering the cell from the solution, the cell expands and can rupture.
Answer: 3
Explanation:
The polymerase chain reaction, known as PCR, is a technique in molecular biology developed in 1986 by Kary Mullis. Its objective is to obtain a large number of copies of a particular DNA fragment, starting from a minimum; in theory it is sufficient to start from a single copy of that original fragment, or mold.
<u>This technique builds on the natural property of DNA polymerases to replicate DNA strands by using alternating high- and low-temperature cycles to separate newly formed DNA strands from each other after each phase of replication, and then allowing the DNA strands to re-assemble so that they can be duplicated again</u>.
Since the temperatures of the cycle (95°C in the DNA denaturation phases) imply the immediate denaturation of any protein, thermostable DNA polymerases are used, extracted from microorganisms adapted to live at these temperatures, which are restrictive for most living beings. Today, the whole PCR process is automated by an apparatus called a thermal cycler, which allows the reaction tubes to be heated and cooled to control the temperature required for each stage of the reaction.
Once the first cycle is completed, we have 2 copies of the original sample. Because there are 2 strands of DNA and each of one is copied. At the end of the second cycle, there are 4, and at the end of the third cycle 8... If the cycles occur a number "n" of times and assuming that the number of DNA copies doubles in each cycle, we obtain a DNA quantity of 2^n, so the amplification is done in the form of geometric progression.
So, three cycles are needed to increase eight times in quantity, because 2^3= 8.
