Answer:
D) lowering the energy for activation.
Explanation:
Just like chemical catalysts that accelerate the rate of chemical reactions, enzymes are biological catalysts that accelerate the rate of biochemical reactions.
Majorly, a catalyst works by lowering the activation energy required for a specific reaction. The lower the activation energy for a reaction, the faster the rate of that particular reaction.
Hence, an enzyme accelerates the rate of reaction by lowering activation energy of the reaction.
Answer: the cuticle slows down the rate of water loss.
Explanation: the spongy layer contains chlorophyll although few. Photosynthesis occurs in the chloroplast.
Plants need chlorophyll because it captures sunlight which helps in the splitting of water molecule during photosynthesis ,thus they need it to manufacture their food.
The correct answer is A. Type I
Explanation:
In biology, a survivorship curve is a type of graphic that shows the rate of survival of individuals of one species along time. This type of graphics includes three types of curves. The first one or Type I occurs when individuals can survive during the first ages but by the middle and end of life, the survival rate falls. The second one or Type II occurs in species in which survival rate slowly declines as time passes. Finally, in the third curve or Type III, there are species that experience difficulties for surviving at the beginning of life by then survival rate stay the same. In the case of humans, most scientists classified our species in Type I because at early age survival rate is mainly high as only a few percentages of the population dies at a young age, but after middle age and in elderly the death rate sharps and therefore survival rate falls.
In this case, the full medical history of the patient is not endorsed. A patient undergoing treatment of benign prostatic hyperplasia with tamsulosin, an alpha receptor antagonist, will not usually present with deranged clotting mechanisms. From the choices, only warfarin; which actions to antagonize the action of vitamin K thereby significantly reduce vitamin K dependent clotting factors such as factor II, factor VII, factor IX, and factor X. In reducing the levels of vitamin K dependent clotting factors, clotting time; both intrinsic (prothrombin time) and extrinsic (activated thromboplastin time) pathways will be deranged.
A type of learning in which a stimulus acquires the capacity to evoke a response that was originally evoked by another stimulus is known as classical conditioning.
In classical conditioning, a stimulus gains the ability to elicit a response that was first elicited by another stimulus. Almost by accident, Pavlov made this type of learning discovery while studying the canine digestive system.
He had surgically inserted a tube into a dog's salivary gland, which was used to collect the saliva the dog made after being given food powder to chew on. Before they were given food, several of Pavlov's dogs started to salivate.
