When a person has linked a neutral stimulus and an unconditioned stimulus so that now the neutral stimulus triggers the conditioned response, <u>acquisition</u> has occurred.
<u>Explanation:</u>
A trigger that in the beginning causes no specific answer other than attention concentration is understood as "a neutral stimulus". In operant conditioning the neutral stimulus becomes a conditioned stimulus when used in combined way with an unconditioned stimulus.
Now let us say, for instance, you need to take your child to the pediatrician for a shot. The pediatrist hits a buzzer before the shot to call her nurse to come in and help her conduct the vaccine. Here the buzzer's noise is the neutral stimulus, as it generates no reaction from the infant, but the child knows that.
<span>Plant species are dying out; seeds and nuts have all but vanished. Of these four finch species, but Finch 4 is most likely to survive under these conditions. So the answer would be letter D.</span>
Seminal vesicles
prostate gland
<span>bulbourethral glands
</span>The male reproductive system is designed to make sperm or male gametes and is adapted to provide for the delivery of these gametes to the female to allow for fertilization. It consists of:1. Testes- produces sperm and the hormone testosterone2. Scrotum- pouch enclosing the testes keeping the sperm at an optimum temperature.3. Vas deferens- tube that carries sperm away from the testes.4. Prostate gland- adds lubricating and other fluids to the sperm.5. Urethra- tube through the penis carrying sperm to the outside of the body.<span>6. Penis- adaptation for internal fertilization of the female.</span>
The question is incomplete as it does not have the options which are:
-Can the plant survive with few nutrients and little water?
-How large does the plant grow?
-What color is the plant?
-Does this plant have small or large leaves?
-How many offspring does this plant produce at one time?
Answer:
Can the plant survive with few nutrients and little water?
Explanation:
Pioneer species are considered those species of plants which are the first to colonize the habitat in ecological succession.
They are considered the pioneer as they grow in the limited resources either on the barren lands or on the rocks. These plant species plays an important role in succession as they enrich the soil with the nutrients as they can produce acidic compounds which can degrade the rocks or them upon degradation and decomposition enrich the soil with nutrients.
Since they are the first species to colonize an area without nutrients therefore whether the species will grow in the limited nutrients and the water will be most relevant.
Thus, the selected option is correct.
Through photosynthesis by cyanobacteria and plants containing chlorophyll pigment
this is the only natural process which releases the life supporting gas oxygen into the atmosphere
