Answer:
fixed action pattern, key stimulus; key stimulus, fixed action pattern
Explanation:
- An innate behavior which specific to a species and is highly stereotyped is termed as a fixed action pattern.
- This behavior occurs due to a neuronal network that is hard-wired in the species and the response is said to be generated following a key stimulus.
- A key stimulus is the one that generates a fixed action pattern and this is also called a releaser.
- A key stimulus can be in the form of shape, sound, color, or a combination of these.
- In this case, the red spot is a stimulus for the chicks which causes them to peck at their parent's bill, and hence, the red spot is a key stimulus, and pecking of the chicks is a fixed action pattern.
- The parents regurgitate the food only when the chicks peck at their bills, so pecking is a key stimulus for the parents which causes them to regurgitate the food which is a fixed action pattern.
Answer:
Methionine- Serine- Histidine- Aspartate- Glycine- stop
Explanation:
Translation, which occurs in the ribosomes, is the second stage of protein synthesis where mRNA transcript is used to synthesize a peptide chain that eventually forms a protein. The mRNA sequence is read in a group of three nucleotide called CODON. Each codon specifies a particular amino acid, which is read and added to the growing peptide chain.
In this question, a DNA sequence reds 3'- TACAGGGTGCTACCCACT-5, the
mRNA sequence from this DNA during transcription will be:
AUG UCC CAC GAU GGG UGA
From this mRNA sequence, the peptide chain that will result following translation is:
Methionine- Serine- Histidine- Aspartate- Glycine- stop
Answer:
<h2>
A. precipitation</h2>
Explanation:
because the after evaporation and condensation
it rains which is precipitation
Explanation:
Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.
