Answer:
the answer would be B maybe
Explanation:
The wavelengths of ultraviolet, X-ray, and gamma-ray regions of the EM spectrum are very small. Instead of using wavelengths, astronomers that study these portions of the EM spectrum usually refer to these photons by their energies, measured in electron volts (eV). Ultraviolet radiation falls in the range from a few electron volts to about 100 eV.
Answer:
D.The light-dependent reactions absorb sunlight and transfer the energy to electrons.
Explanation:
Firstly, the organelle that was described as small green organelle inside a cell as noticed by Quinlin is the CHLOROPLAST. Chloroplast is an organelle present in the cells of green plants, in fact, it makes plants green. Chloroplast is the organelle where the unique process of PHOTOSYNTHESIS occurs in plant cells.
However, the photosynthetic process is divided into stages namely: light-dependent and light-independent stages. The light dependent stage, which involves the production of ATP (energy carrier) and NADPH (electron carrier), must PRECEDE the light independent stage or Calvin cycle. Chloroplast contains a pigment called CHLOROPHYLL, which absorbs light energy from the SUN in order to power the light dependent stage of photosynthesis.
Hence, the light-dependent reactions, which absorb sunlight and transfer the energy to electrons must occur first in the organelle.
Answer: D, lifeguard
Explanation:
A social worker is concerned with individuals, families and groups and communities in an effort to enhance social functioning and wellbeing and could be exposed to cancer over time in a bid to work. This depends on the nature of job he is doing.
Cadmium is cancerous so the artist is at risk.
The technician at the nuclear power plant is also exposed to cancerous elements.
The lifeguard is not at risk because his job is to primarily rescue people who are in danger or are drowning in the beach, swimming pool etc.
Answer:
The correct answer would be transcription.
Transcription is the process by which information in the form of a nucleotide sequence of DNA (deoxyribonucleic acid) is copied into the nucleotide sequence of RNA (ribonucleic acid).
The whole process is catalyzed by an enzyme RNA polymerase.
RNA polymerase copies template strand of DNA into RNA.
mRNA then transfer to the ribosomal site for protein synthesis.
