Answer:
Introduction Purpose: Explore the interdependence of organisms by
performing an experiment with lima bean plants and earthworms. Question: How can the presence of one species benefit another in
the same ecosystem?
Hypothesis: If plants grow in soil containing worms, then the
plant growth will be greater, because worms help decompose organic matter and distribute it through the soil in a form that plants can use.
Explanation:
Answer:
Transcription factors
Explanation:
This is because Eukaryotic gene expression is regulated by transcription factors and RNA processing, which occur in the nucleus, and during protein translation, in the cytoplasm.
Transcription in eukaryotic cells is controlled by proteins . These proteins then bind to some specific regulatory sequences and try to control the activity of RNA polymerase. The Gene expression is regulate by transcriptional regulatory proteins . Also ,the packaging of DNA into chromatin and methylatiin indicate levels of complexity to the control of eukaryotic gene expression.
Reduces carbon monoxide emissions from gasoline and improves fuel octane
Answer:
A
Explanation:
For a recessive gene to affect the child they must inherit two recessive alleles because if a dominant allele is inherited than the dominant trait will be the one that is expressed in the child. The only way to get two recessive alleles is to inherit one from both parents so the father must also carry the recessive allele. This means A must be the correct answer.
