<span>Gene Expression is the progression wherein the
information from a gene is used in the combination of a functional gene
product. In eukaryotic cells, genes are delimited by repressors as well as by transcriptional
activators. The repressors will muddle to the specific DNA sequences and will constrain
transcription.</span>
Birds
Birds are organisms which utilize a one-way air flow through their lungs to maximize air flow efficiency and <span>oxygen consumption
</span>The process of respiration is essential in the oxygen/carbon dioxide cycle. Respiration removes OXYGEN <span>from the atmosphere and produces and releases </span>CARBON DIOXIDE to the atmosphere.answer is letter D.
<span>Respiration driven by a mechanical series called inhalation and exhalation. We inhale or breathe in oxygen and exhale or breathe out carbon dioxide. </span>
The correct answer is:
Plants close their stomata during times of intense heat or drought in order to prevent water loss and maintain homeostasis.
Explanation:
Guard cells tend to open stomata within the day when there are lots of day and close stomata at night when the sun is not present and photosynthesis is not happening. They will also close stomata if the air is dry or hot, which minimizes water waste indoors evaporation.
Potassium is just below the sodium in periodic table in s group !
so the valence electron of sodium and potassium is same and that is 1 !
