The correct answer is
D) gathering food.<span>Caching or hoarding food, is a behavior characteristic for squirrels during winter. They usually do this by putting their food in a shallow hole which will serve as food when resources are scarce in winter. Also, squirrels maximize their food consumption and body mass making the reserves that will help the animals survive.</span>
The two sources of information used to direct the expression of genes during various stages of development are Transcription and Translation.
<h3><u>Explanation:</u></h3>
Both of them combined is called gene expression.Transcription is the process of sharing information stored in a DNA to RNA.
The process of translation is carried out in cytoplasm. Here, the mRNA, in which stands for messenger, send messages to a more complex and specialized molecule called the ribosome. The sequence present on the mRNA base is read by the ribosome.
Transcription takes place in nucleus and translation takes place in Cytoplasam. The products of transcription are mRNA, tRNA, rRNA. The products of translation are Proteins.
Metallic bonding is the type of bonding for metallic elements. Ex.) Lead, Mercury, Tin, Cobalt, etc. (Check periodic Table)
Generally, 10% of total available energy is transferred to the next trophic level in any food chain. Rest about 90 % of the stored chemical energy is lost as heat, a by-product of respiration. Let’s assume a 10% transfer rate, starting from producer (100%), primary consumer (10% ), secondary consumer 1%) and tertiary consumer have (0.1%). Therefore, quaternary consumers will have less than 0.1% of energy. Thus, statement is true.
Answer:
hydrophilic- attracts water
hydrophobic- repels water
Explanation:
A cell membrane is a bilayer of phospholipids. They have a hydrophilic phosphate heads, and hydrophobic fatty acid tails.
so in the cell membrane they would arrange like this:
The heads are point outwards as they attract water, and tails inwards as they repel water.
Hope this helps!
