Answer:
The sugar molecules thus formed contain carbon, hydrogen, and oxygen: Their hydrocarbon backbones are used to make amino acids and other carbon-based molecules that can be assembled into larger molecules (such as proteins or DNA), used for example to form new cells.
The cell membrane's main trait is its selective permeability, which means that it allows some substances to cross it easily, but not others. Small molecules that are nonpolar (have no charge) can cross the membrane easily through diffusion, but ions (charged molecules) and larger molecules typically cannot.
Answer:
All the statements are true and the correct option is;
D. All of these are true
Explanation:
Ecosystems change over time. ... Sudden disruptions such as volcanoes, floods, or fires can affect which species will thrive in an environment. Other disruptions are caused by human activities
An ecosystem ecosystem is an area where a community living (biotic) and non living (abiotic) things such as plants, animals, other organisms, landscape, natural sources and weather interact to create an apparently sustainable system
An ecosystem undergoes several changes over time due to environmental disturbance which results in the variation of the ecosystem's structure and change rate due to the natural disturbance and/or human activity
Therefore all the statements are true.
In a dipstick urinalysis, red blood cells, glucose, and proteins all indicate abnormality but urea does not.
<h3>Abnormality urine</h3>
The components of normal urines include urea, chlorine, creatinine, and nutrients such as potassium, sodium, and other dissolved ions.
Proteins can also be present at a very minute level. However, the presence of red blood cells, glucose, and too much proteins is usually an indication of abnormality with an underlining health problem.
