A bird catches and tries to eat a caterpillar. The caterpillar has a bad taste, so the bird lets the caterpillar go. The next ti
NNADVOKAT [17]

Answer:

The correct option is trial and error learned behavior

Explanation:

A trial and error learned behavior is a type of behavior in which an organism attempts to or tries something new which makes it (the organism) accept the reality of that thing or situation. This means that if the attempt is successful or pleasurable, the organism will attempt it again and if it's not, the organism will avoid that thing.

This is what was described in the question with the bird trying to eat the caterpillar but found it unpleasurable which made it to start avoiding it afterwards.

If polar is positive and non-polar is negative then why can’t a polar molecule pass through the non-polar phospholipid membrane
Ierofanga [76]

Answer:

Because of the chemical and structural nature of the phospholipid lipid by layer the lipid soluble molecule can just pass the lipid membrane and some small molecules can also pass freely.

Explanation:

as we know that the homeostasis is an important process for a  living cell to maintain it self so for the the exchange of materials between the external and internal environment is must so for that it exchange material with the outside environment of the cell.as the cell membrane is semipermeable(mean allow some molecule to pass(lipid soluble) and not others(lipid non soluble) to pass through the membrane.the cell membrane is selectively permeable due to its nature and chemical composition the chemical composition is lipid and  phosphate and glycerol(head) with fatty acid that may b saturated or unsaturated(tail).so finally all those molecule which are polar can not pass through the membrane and  non polar can pass the membrane.The size of the molecule is also a factor on which the permeability depends.

____________ is translated by the ribosomes and contains the code that specifies the sequence of amino acids in a polypeptide ch
HACTEHA [7]

mRNA (Messenger RNA) is translated by ribosomes and contains the code that specifies the sequence of amino acids in polypeptide chain.

A single-stranded ribonucleic acid molecule is known as messenger RNA(mRNA) plays a major role in <u>translation</u>.

Translation is the method by which an mRNA codes for a certain protein. mRNA provides the template for<u> protein synthesis</u>.

The ribosome translates the mRNA that is produced from the DNA into a chain of certain amino acids and<u> protein synthesis</u> is facilitated by this <u>amino acid</u> sequence.

<u>The genetic code</u>, which connects the DNA sequence to the amino acid sequence of proteins, is used to "read" the mRNA. Each group of three nucleotides in mRNA forms a codon, and each codon corresponds to a particular amino acid (triplet code).

Thus mRNA contains the code that specifies the<u> sequence of amino acids</u> in a polypeptide chain.

Readme [11.4K]

Answer:

3/8

Explanation:

Martha has a widow's peak (dominant trait) and attached earlobes (recessive trait).

Martha's dad had a straight hairline (ww) and unattached earlobes (Ee, because she has the recessive alleles ee and both parents give us one allele).

This tells you that martha has a mother with at least one of both alleles dominant for widow peak and at least one recesive allele of attached earlobes

So, martha's alleles are: Ww and ee.

If she marries a man that is heterozygous for both traits (Ww and Ee) the probabilitys are

Ww Ee x Ww ee: WWEe, WwEe, wWee, and wwee

Jonathan used the following soil triangle to identify a sample of soil as sandy clay.
sineoko [7]

The description of soil according to Jonathan is as follows:

  • Mostly large grains, with a gritty texture, 45% sand, 5% clay, and 45% silt ---- Silty loam soil.
  • Mostly large grains, with a sticky texture, 55% sand, 40% clay, and 5% silt ----- Sandy clay soil.
  • Mostly small grains, with a sticky texture, 30% sand, 50% clay, and 20% silt ----- Clay soil.
  • Mostly small grains, with a smooth texture, 30% sand, 5% clay, and 65% silt ----- Silty loam soil.

<h3>What is Soil Texture?</h3>

Soil texture may be defined as a classification of soil on the basis of its physical appearance, texture, and properties.

In this question, the texture and composition of other soil are illustrated briefly with respect to each common soil type.

Therefore, it is well described above.
