The correct answer is: c. Transcription
Transcription is the first step of gene expression in which DNA molecule is copied (transcribed) into RNA (mRNA) by RNA polymerase. The process of transcription is divided into three phases:
1. Initiation
• RNA polymerase with transcriptional factors bind to gene promoter
• RNA polymerase unwinds DNA double helix (transcription bubble is formed)
2. Elongation
• RNA polymerases adds nucleotides complementary to DNA
3. Termination
• RNA polymerase gets to stop codon (transcribes a sequence of DNA known as a terminator)
• Formed complementary RNA strand is released from DNA-RNA complex
Complete question:
___BLANK___ system contains glands that secrete hormones into the bloodstream, whereas the ___BLANCK__system secretes substances through ducts.
Answer:
The ENDOCRINE system contains glands that secrete hormones into the bloodstream, whereas the EXOCRINE system secretes substances through ducts.
Explanation:
Those tissues that produce hormones might be classified as:
- endocrine glands (produce hormones exclusively),
- exocrine glands (produce hormones and other secretions),
- non-glandular tissues that secrete hormones but are not glands.
- Endocrine organs, also known as ductless glands or endocrine glands, release their secretion directly to the bloodstream. Blood transport hormones to target cells, tissues, and organs, where they stimulate a change in metabolic activities
- Exocrine glands release their secretions to a duct of different tissues where they act, such as the internal or external surface of cutaneous tissues, stomach mucose, or pancreatic ducts.

The manila grasshopper has several benefits to ecosystem and humans.
- In general it facilitates decomposition and regrowth of plants by creating a balance between the types of plants that grow well.
- Like other animals, grasshopper eats and excretes in the soil. Its waste increases the fertility of the soil and promotes plant growth.
- Grasshopper body is rich in protein, on its death microorganisms break down its body and enrich the soil and helps plants to grow.
- Grasshoppers prevent over growth of plants as it consume about 10% of the available plant biomass, thus maintain ecological balance.
Answer:
A magnet keeps a cabinet door closed. The Sun pulls on Earth as Earth moves around the Sun. The protons in the nucleus of a carbon atom are held together.So this is an example of the strong force in action.
