Answer:1
1. It can be use as source of energy and fuel.
2. It can be use to build body tissues and bones.
3. To fight pathogens or fight infections.
4. It can be use for bones development.
Explanation:
Biomass are Renewable source of organic matter that can be use for energy. These includes wood, seaweeds, crops and animal wastes. Biomass get it's source of energy from sunlight. All biomass contained stored energy from sun which is gotten from the process of photosynthesis where green plants uses carbondioxide and water with light energy to produce sugars. Animals get their energy from consuming sugars.
Biomass eaten by animals can be use in four ways.
. It can be use as source of energy and fuel.
2. It can be use to build body tissues and bones.
3. To fight pathogens or fight infections.
4. It can be use for bones development.
The correct answer is: b. It is free to bind to another promoter and begin 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.
RNA polymerase is also released and can transcribe some other gene by binding to its promotor. RNA polymerase will transcribe just the genes whose products are needed at a particular moment.
A) One species always outcompetes the other until only one species remains.
Answers
The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.
Digestive System gets nutrients (good) from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go.
The excretory system removes waste from the body. remove waste from the blood. The digestive system breaks down the food you eat into nutrients that provide energy and building materials for cells. The digestive and excretory sytems work together to process the food that you eat.
