Answer: Primary
Explanation: The primary level of protein structure explains the sequence of amino acid linked together by peptide bonds to form polypeptide chains . A slight change in the amino acid sequence of Hemoglobin can alter hemoglobin function.
The primary level of protein structure is essential in the function of the protein any alteration in the amino acid sequence can disrupt the function of the protein.
Based on the information above, the correct answer to the question would be a. Percy will likely make an external attribution. Since he does not remember anything that would cause him to think that he can be a reason why one of his windows is broken, then he most probably will attribute it towards an external event.
A sperm cell and an egg cell fuse to form which structure?
zygote
zygote = a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum
NOT FETUS
Answer:a. Rods and cones, bipolar cells, ganglion cells, optic nerve
Explanation:
The bipolar cells are present in between the rod and cone and ganglion cells.
The function of bipolar cells is to transmit signals from the photoreceptors (rod and cones cells) to the ganglion cells. The signals are then transferred to the brain via optic nerves where visual image is created.
Answer:
The humans use this limb to grab things, body language, and sign language.
The dogs use this limb for all kinds of weight-bearing activities like walking, jumping, running et cetera.
Birds use this to fly and whales use it as flapper.
The limbs of all these four animals are the example of homologous organs that is, they all are similar in structure but adapted to perform different functions during the course of evolution.
For example, in all four organisms, the limb is made up of the same set of bones such as humerus, radius, ulna, carpals, metacarpals, and phalanges.
Homology in structure shows that they must have evolved from a common ancestor and diverge to perform different functions as an adaptation to the contrasting environment.
