Answer:
Faciliated diffusion, which requires a carrier protein but no cellular energy. The energy for this process is provided by the concentration gradient of the substance being transported.
Answer:
The flowers which contain both male and female reproductive organs are known as full or bi flowers. They will self-pollinate themselves. Examples: Tulip, Sunflowers and Lily
Explanation: did it awhile ago hope this helps you pass!
Enhancers are eukaryotic DNA sequences that can be used to elevate transcription and have variable positions and orientations.
The correct answer is - Its electrons are used to form NADPH.
On receiving light energy, electrons are expelled from the reaction center of photosystem II. The expelled electrons finally reduces oxidized NADH⁺ to NADH. The oxidized reaction center of photosystem II split water into protons, electrons and oxygen. The electrons released from water reduces oxidized reaction center of photosystem II. Thus, oxidized reaction center of photosystem II gets back its expelled electrons. Therefore, electrons from water forms NADH.
Multicellular organisms do this by assigning specific roles to specific cells. This enables various cells within a larger organism to collaborate in order to preserve homeostasis. Since they are made up of just ONE type of cell, unicellular organisms do not need cell specialization to maintain homeostasis.
