Snakes can live up to 9 years. They slither up to 18 mph. Snakes are reptiles that are elongated, limbless, and carnivorous. Another interesting thing about snakes is that they don’t have eyelids. The last fact is that snakes can open there mouths up to 150 degrees so they can swallow there prey.
Answer:
4.
Explanation:
Synteny oe syntenic gene is defined as the physical co-localization of genetic loci on the same chromosome within a speciesand inidvidual.
In the beginning of the meiosis process, when genes are present in the same chromosomes but very far, they undergo indepedent assort due to homologous recombination and the random exchnage of matching fragment in homologous chromosomes takes place. During the crossing over there are very less chances that all types of gametes are produced accurate frequency.
Hence, the correct answer is 4.
What you meant must be the adaptive advantage of the frogs' lungs. Frogs are considered as amphibians wherein the have this unique ability to reside either on land or in water. Their specialised lungs could be responsible to these which makes them capable of breathing oxygen in water and land.
Answer: It is approximately the membrane potential at which the electrochemical gradient for Na+ is zero.
Explanation:
The charge in plasma membrane occurs with diffusion and electric fields.
For example, if there are two solutions, let's assume solution X and Solution Y are separated by a porous barrier (to diffuse in equal proportions).
The fundamental principle of diffusion states that solution from a high concentration diffuses to a lower concentration.
For instance, if the X solution contains 40 sodium ions and 40 chloride ions, the Y solution only has 30 sodium and 30 chloride ions. Due to the diffusion, these two solutions will mix and reach a steady-state.
The like charges repel, and opposite charges attract.
