The Sun is the basic source of energy for the Earth which affect the growth of all living things and the Sun also affect the all the biochemical processes. We know that the amount of radiation from the Sun changes day by day due to the distance of the Earth from the Sun. The rate of Solar energy affects the Earth in two ways.
The rate of solar heating which directly affects the processes like the evaporation and condensation and indirectly it affects the cloud forming processes of the Earth. The rate at which the solar energy reaches the Earth is called as the Total Solar Irradiance or TSI. This affects the climate of the Earth in many ways.
The change in rate of cloud formation increases of decreases with the distance of the Sun from Earth and hence a warm, moderate or cold climate is formed
It also affects the formation of winds due to the low or high pressure in the water bodies and hence affect the climate in the coastal areas.
The tropical areas have hot and humid climate due to the equator which has maximum exposure to the Sun’s heat.
Hence, the Sun is one primary feature that affects the climate in the Earth.
Answer:
The dominant phenotypes are Long flagella and one vacuole, and the recessive phenotypes are small flagella and two vacuoles.
Explanation:
As you can see in the attached table
1. For the size of the flagella we gave that:
- 241 organisms have long flagella
- 79 organisms have short flagella,
As there are more organisms with long flagella we can conclude that this is the dominant phenotype while the short flagella is the recessive phenotype.
2. For the number of vacuole we have:
- 247 organisms have one vacuole
- 73 organisms have two vacuole
As there are more organisms with one vacuole we can conclude that this is the dominant phenotype while having two vacuoles a is the recessive phenotype.
Then
Dominant phenotypes = Long flagella and one vacuole
Recessive phenotypes = Short flagella and two vacuoles
The answer will be A because mitosis usually separate the sister chromatids to sister chromosomes to form two diploid cells. In meiosis, the goal is to have four haploid cells. To form that, cells need to undergo cell division two times. In the case of meiosis I, sister chromatids stay joined together until it reaches meiosis II. Then, the sister chromatids will separate starting at anaphase II in meiosis II. For example, if you start with 92 chromosomes (46 chromatids) during meiosis I, at meiosis II you will have two cells with 46 chromosomes (23 chromatids). By the end of meiosis II, you should form 4 haploid cells that contains 23 chromosomes.
Answer:
During the process of translation, the codon UAC sets up the open reading frame in the mRNA (messenger Ribonucleic acid). The codon UAC corresponds to ATG in the DNA. It codes for the amino acid methionine.
Explanation:
The determination of the open reading frame is important in the process of translation and protein formation. The start and stop codons determine the open reading frame. In DNA (deoxyribonucleic Acid), there are typically six reading frames. The correct frame is determined and the translation is started.
The ATG codon in the DNA sets the reading frame in most of the eukaryotes. Different frames can be started by beginning with either 'A', 'T', or 'G'.
