Cell membrane - the thin layer of protein and fat that surrounds the cell, but is inside the cell wall. The cell membrane is semipermeable, allowing some substances to pass into the cell and blocking others.

Select the correct days.
san4es73 [151]

Answer:

Monday, Saturday, and Sunday

Explanation:

To decide which days would be okay for her team to conduct the experiment that involves, canopy fogging, here are some information and facts that we should have in mind:

1. Canopy fogging is a technique employed in the collection of insects in the study of forest insects. It basically involves the use of a chemical that would only affect only insects, such as pyrethrine.

2. A sprayer, which may be in the form of a machine is used in spraying this chemical in the form of aerosol with the aid of a blower.

3. Living insects are mostly collected this way for research and studies.

4. Canopy fogging is not usually done when the weather is windy and/or raining. Wind and rain would disrupt the effectiveness of the chemical used in fogging. Wind would blow away the tiny particles of the chemicals being sprayed. Rain may also wash away the particles, and rain might come with storms, hence wind would be present also.  

5. Canopy fogging can be done in a sunny and windless weather with no storm.

<em>So therefore, </em><u><em>Monday, Saturday and Sunday</em></u><em> should be ideal days for carrying out canopy fogging since rain and/or wind are absent in these days. </em>

Explain how the chemical properties of water affect the solubility of inorganic and organic molecules and how is this so importa
Delvig [45]

Explanation:

Water molecules are polar, meaning they have dipole polarities. The Hydrogen end is partially positive while the Oxygen end is partially negative. This is due to the fact that oxygen has a higher atomic mass and hence attracts most of the electron cloud of the molecule towards its end.

This property of water is very important because it is able to dissolve polar molecules while non-polar molecules do not dissolve. This is an important property in the body of organisms because, for example, water helps in the folding of proteins (by interacting with polar motifs of a protein) hence ensuring the protein maintains their functional structural forms.

Water also dissolves significant polar molecules that are utilized by the body, such as glucose, and helps in their transportation within the body. Water is also significant in the diffusion of hormones used in cell signaling, e.t.c.  

Water is also able to dissociate ionic compounds, such as sodium chloride, that are important in the osmotic pressure homeostasis of cells.

Most proteins in present-day mitochondria are made by cytoplasmic ribosomes from mRNA transcribed from nuclear genes. Can this f
igor_vitrenko [27]

Answer:

Yes; this difference from bacteria is unimportant, because the many similarities between bacteria and mitochondria provide sufficient evidence in favor of the hypothesis.

Explanation:

The passage speaks about the protein synthesising ability of bacteria and mitochondria. The bacteria are single-celled microorganism and they are prokaryotic. They lack membrane bound organelles such as mitochondria. But both mitochondria as well as the bacteria has certain similarities.

The structural similarities between the cell organelle and the organism shows favourable evidence that most proteins in present-day mitochondria are made by cytoplasmic ribosomes from mRNA transcribed from nuclear genes.
