why do scientists use binomial nomenclature to name organism
Answers
Answer:
Binomial nomenclature is used to avoid confusion among the names the organisms. ... If we call all these organisms by different names, no organism can ever be identified globally.

Answers
Answer:
Implantation is the mechanism by which a blastocyst, which is passing through the uterus as a developing embryo, makes contact with the uterine wall and remains bound to it before birth. The uterine lining (endometrium) undergoes several internal modifications in order to allow for the emerging blastocyst to bind to it.

When environmental conditions change, selection can cause a change in the distribution of phenotypes of that species. Which of the following trends would provide evidence of disruptive selection in response to environmental change?
A shift in a population's frequency curve from an intermediate phenotype to an extreme phenotype
A shift toward equal distribution of all phenotype frequencies, including intermediate and extreme phenotypes
An increase in the frequency of extreme phenotypes and a decrease in the frequency of intermediate phenotypes
An increase in the frequency of intermediate phenotypes and a decrease in the frequency of extreme phenotypes
Answers
Answer:
One of the extreme phenotypes has the highest fitness. The bell curve shifts towards the more fit phenotype.
so I think w ould say the second one
Explanation:

An increase in the frequency of extreme phenotypes and a decrease in the frequency of intermediate phenotypes

Snapdragons show incomplete dominance for the flower color trait. A cross between snapdragon plants with red flowers and plants with white flowers produces F1 offspring with pink flowers.
When an F1 plant is self-pollinated, what percentage of its F2 offspring will be expected to have red flowers
Answers
Based on inheritance laws, it is expected none of the offspring will have red flowers.
What is incomplete dominance?This occurs when a specific trait or allele is not completely expressed. In this case, the colors red and white are not completely expressed but they mix in the offspring.
What would be the dominant trait of the F2 generation?Considering the pink flower will self-pollinate, it is expected the F2 generation has exactly the same traits as the F1 generation because there are no new genes or traits being combined. This means none of the F2 offspring will have red flowers, instead all plants will have pink flowers.

Prozac, Zoloft, and Paxil are called SSRIs because they a decrease the release of oxytocin in the endocrine system in anxiety disorders. b slow the normal reuptake of excess serotonin from synapses in depression. c successfully level the emotional highs and lows of bipolar disorder. d stimulate the release of norepinephrine into the bloodstream in depression. e increase the number of receptor sites for dopamine in schizophrenia.
Answers
Answer:
b slow the normal reuptake of excess serotonin from synapses in depression
Explanation:
Serotonin is a neurotransmitter that transports signals or messages between neurons.
Although other neurotransmitters are involved in depression affection, alteration in serotonin levels is an important cause of the disease.
Affected people that express depression show an alteration of the normal serotonin levels in the interneuronal space. There is a noticeable decrease in molecule concentration due to an increase in its reuptake.
The substances used in the depression treatment belong to the SSRI group. SSRI means Serotonin Selective Recapture Inhibitor. It means that these substances inhibit the reuptake of serotonin that usually occurs in affected patients.
ISSR treats depression by enhancing serotonin levels and its transmission by blocking the reuptake in neurons. In this way, there is more serotonin available to improve communication between neurons.
ISSRs are selective because their principal target is the serotonin molecule and not the other neurotransmitters.

16. The elements in group_
are very unreactive.
17. The elements in group_
react very violently with water.
Answers
Answer:
14 Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.
15 The halogen group of elements is the most reactive of the nonmetals. It is also the most reactive group of all chemical elements. Fluorine is the most reactive element in this group. Halogens are highly reactive because they are all electronegative.
16 Group 8A — The Noble or Inert Gases. Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.
17 Group 1: Alkali Metals
Group 1 elements are called alkali metals because of their ability to displace H2(g) from water and create a basic solution. Alkali metals are also known to react violently and explosively with water.
