The wind, or bees and butterflies carry the pollen to places where it is obsolete.
Answer:
In a cell it is called the VACUOLE.
Explanation:
The vacuole typically stores liquid enclosed by a membrane.
Answer:
C
Explanation:
<em>The correct answer would be the group that was given a placebo.</em>
A control group in an experimental study is the group that is subjected to all other conditions except the variable whose effects are being determined during the course of the experiment.
<u>Since the main goal of the research is to evaluate the effectiveness of the HPV vaccine, the difference between the experimental and the control group would be the vaccine.</u> Instead, the control group would be given a placebo - a substance that is designed not to have any effect but looks like the vaccine itself.
<em>Correct option: </em><em>C</em>
<h2>
Answer:</h2>
I believe the correct answer is D. React to stimuli from outside the body.
<h2>
Explanation:</h2>
Hormones are types of proteins that produce responses hand in hand with neurons but they are much slower and longer lasting. They can act on the same cells and in that instance they will be called autocrine hormones. Those that act on neighbouring cells are called paracrine hormones while those that act on far away cells are called endocrine hormones.
<h2>Further Explanation:</h2><h3>a. Initiate behavior and reproduction:</h3>
This is a function of hormone(s). Hormones such as testosterone can initiate both behavior of an organism and also stimulate reproduction. Testosterone causes maturation of sex features and sperms in males to initiate reproduction. Other hormones with such functions include: Estrogen and adrenaline.
<h3>b. Coordinate the production and use of energy:</h3>
Some hormones conduct this function by regulation metabolism in the body. These include: Insulin in intake of glucose for energy and glucagon in maintaining blood glucose levels. Corticosterone also responds in stress to maintain energy.
<h3>c. Maintain nutrition and metabolism:</h3>
Nutrition can be maintained by hormones such as ghrelin that stimulates appetite, insulin in intake of glucose, leptin and glucagon.
<h3>d. React to stimuli from outside the body</h3>
This is not a function of a hormone but rather the function of a neuron. Neurons have specific structures called denrites that recieve signals/stimuli from outside the body then convert them to nerve impulses that are transmitted to the brain which produces another impulse to be taken to a specific site to produce a desired response.

Answer:
the correct answers are as follows
12:
b. Testcross- an organism with dominant phenotype but unknown genotype is crossed with homozygous recessive organism for the same trait. Based on the results obtained, if all offsprings have the same phenotype, then the parent is homozygous, but when a 1:1 ratio is observed in the offsprings, then the parent is heterozygous.
13.
e. Watson and Crick- they both used the crystallographic images from Franklin, analyzed them to first elucidate the 3D structure of the DNA and propose it to the world.
14.
c. Intracellular and commonly found in the cytoplasm- the receptors of steroid hormones are generally present within the target cell either in the cytoplasm or nucleus, since they alter gene expression.
15
e. Certain prokaryotes/bacteria- this is a process that will enable disease-causing pathogens to communicate and cooperate with their group, by the release of autoinducers that increase their cell density.
