Answer:
i would say A. Both are needed as a reactant of cellular respiration.
Explanation:
While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. ... Without oxygen, much less ATP would be produced.Aug 31, 2018
1. Temperatures are extreme; mostly high or very cold temps (only winter and summer it feels like). They have changed over years.
2. Polar ice caps (glaciers) are melting drastically.
3. Habitats/ecosystems such as the coral reef are suffering and are expected to disappear over the course of 10-20 years
Answer:
The correct answer will be option-A.
Explanation:
Recombination is a process in which the DNA sequences get exchanged between two homologous chromosomes. It occurs during gamete formation and is the basis of genetic diversity.
The process requires many enzymes, the key enzyme of which is Recobinase A or RecA protein which catalyzes the homologous recombination using ATP as an energy molecule.
RecA binds to the single-stranded DNA at the break site and forms pre-synaptic structure. Thus, it initiates the reaction of strand exchange and is the correct answer.
Answer is b. flux
Different types of micro-organisms either live in on the human body. Microorganisms live on the skin or in the gastrointestinal tract. Collectively these microorganisms are called microbiota. An individual's microbiota is in a constant state of flux (state of flowing)
Answer:
Natural selection is a process where organisms that are better adapted to an environment will survive and reproduce.
This means that the advantageous alleles of this variant organism are passed on to offspring. Over many generations, the process of natural selection leads to evolution occurring. Charles Darwin was a famous English naturalist.
