Answer: B. Blood dripping from the murder weapon.
Explanation: In bloodstain pattern analysis, blood spatters behave in accordance with some scientific laws in relation to what caused the bloodshed, the position of the victim and the perpetrators, and the velocity at which the blood is spattered. Since the blood trail is leading away from the stabbed victim, the blood trail is most likely created by the dripping of blood from the murder weapon
The endothermic process is any process which requires or absorbs energy from its surroundings, usually in the form of heat. It may be a chemical process, such as dissolving ammonium nitrate in water, or simply the melting of ice cubes.
Answer:
The correct answer is "In order to create a synthetic life form it would be necessary to know the function of every gene and include them in the organism".
Explanation:
The most common approach of studies using recombinant DNA technology is to insert a desirable gene from one organism into a host organism. This approach is much more feasible that creating a synthetic life form because, in order to create a synthetic life form, it would be necessary to know the function of every gene and include them in the organism. Even though the whole DNA sequence of many organisms is known (including humans), the function of the entire sequences of the genome is yet to be understood.
Answer:
option B) is correct
Explanation:
The all or none response means that if a muscle contracts, it will contract completely. Thus implying the all or none law which states:
The potential of a response of a muscle fiber or nerve cell is independent of the potential of the stimulus. If a stimulus is more than a certain critical value it will trigger muscle fiber or a nerve. Most importantly resulting in either an all-or-none response thus reducing possibility of any information loss.
Answer:
They are opened either by the binding of ligands or by changes in electric potential across the membrane
Explanation:
Ion channels are the integral membrane proteins that form pores or holes for the transport of specific ions, such as potassium ions (K+), Na+, etc. Most ion channels are selective and allow only a single type of ion to pass through. These ion channels facilitate the diffusion of ions down the concentration gradient and do not require ATP.
Ion channels are mostly gated. Some ion channels open in response to change in the concentration of ions and electric charges across the membrane. Some ion channels open and close in response to the binding of specific molecules called a ligand. For example, binding of two molecules of acetylcholine to the receptor on the motor endplate of a neuromuscular junction opens an ion channel in the ACh receptor through which Na+ can flow across the membrane.
