C. both biotic and abiotic factors in earth most ecosystems have both abiotic and biotic systems. They actually need both in order to survive.
Answer:
Option A, 30 C
Explanation:
Plants are able to produce oxygen through the process of photosynthesis and photosynthesis is well carried in the presence of light at a warm temperature of 28 degree Celsius. The rate of photosynthesis falls if the temperature rises above 28 degree Celsius and with falling rate of photosynthesis, rate of oxygen production also falls.
The rate of photosynthesis and hence the oxygen produces also falls when the temperature falls below 28 degree celsius.
Since, the nearest temperature range is 30 degree celsius thus option A is correct
Answer: its wrapped around the proteins, and those proteins make a nucleosome
Explanation:
Answer:
1. 50% of the genome comes from each parent because it is crucial otherwise if the ratio changes, the zygote may not form and if formed the fetus may have some other kind of chromosome number related syndromes etc.
2. Sexual reproduction produces greater genetic variability than asexual methods. This is because of the process of crossing over during meiosis that exchange the segments of chromosome that is necessary for producing mutations and genetic variability.
3. 50% of chromosomes match with each parent because both of the parents contributed 23 chromosomes and exactly 50% of their genome.
4. The gametes must be produced by two different individuals cause that is the main purpose of sexual reproduction and give better survival like this to the forming next generation. Not to mention produces greater genetic variability among species.
5. Plants always produces both eggs because they are hermaphroditic in nature.
