A biologist is using a dichotomous key to identify fish.
1. (a) Has a single dorsal fin ® 5
(b) Has a double dorsal fin ® 2
2. (a) One fin is spiny, the other is smooth ® 3
(b) One fin is not spiny or smooth ® 4
5. (a) Has small fin on back near tail ® 6
(b) Has no fin on back near tail ® 7
6. (a) Has barbs near the mouth ® Catfish
(b) Does not have barbs near the mouth ® 10
7. (a) Tail is asymmetrical ® 8
(b) Tail is symmetrical ® 9
10. (a) Scales are small ® Trout
(b) Scales are large ® Whitefish
What is the next step to take to identify a fish that has a single dorsal fin and no fin on the back near the tail?
step 5
step 2
step 7
step 6
Answer:
The next step to take to identify the fish is step 7.
Explanation:
A dichotomous key is relatively simple to interpret. All you need to do is to:
carefully observe your organism, know some technical terms or have a biological dictionary, and follow the descriptions.The dichotomous key is going to lead you to the answer. Each step states two descriptions -a and b-, that are the potential answers. You need to observe your specimen and see which of the descriptions matches the organism. Once you choose the correct description, the key leads you to the next step. In the next step, the procedure is the same. You have to repeat it until you reach the name of your organism.
So, in this example, our organism is a fish, and we know that it has a single dorsal fin and no fin on the back near the tail. So,
1. (a) Has a single dorsal fin ---------------- step 5
(b) Has a double dorsal fin ----------------step 2
We have two options, single dorsal fin or double dorsal fin. Our fish has a single dorsal fin, so the correct option is (a). By choosing (a), the key sends us to step 5. Note: In the hypothetical scenario of having a double dorsal-finned fish, the correct option would be (b), which would lead us to step 2.
5. (a) Has small fin on the back near tail ---------- step 6
(b) Has no fin on the back near tail -------------- step 7
Again, we have two options, with a back fin near the tail, or without. Our fish does not have any back fin near the tail, so we choose option (b). This option leads us to step number 7. Note: In the hypothetical scenario of having a fin in the back near the tail, we should choose option (a), which leads us to step 6. But this is not the case. So we go to step 7.
7. (a) Tail is asymmetrical --------------- step 8
(b) Tail is symmetrical ----------------- step 9
Once in 7, we need to see if our specimen has a symmetrical or asymmetrical tail. Depending on the answer, we go to step 8 or 9. And so on until we get to know the name of the fish.
Answer: The correct answer is step 7
Explanation: Confirmed correct.

Explanation:
Beginning at the synapse of a neuron, place the events in neuronal signaling in the correct sequence. 1. Ion channels bind the ligand and open. 2. Na is pumped out of the cell, and the membrane potential is restored. 3. Acetylcholinesterase breaks down acetylcholine. 4. Na enters the postsynaptic cell, and the membrane potential changes. 5. Acetylcholine is released into the synapse. 6. Na ion channels close. 4, 5, 1, 2, 6, 3 6, 4, 3, 1, 2, 5 3, 4, 6, 1, 5, 2 1, 2, 3, 4, 5, 6 5, 1, 4, 3, 6, 2
Answer: 5, 1, 4, 3, 6, 2
Explanation:
The synapse is an intercellular approach between neurons or between a neuron and a muscle or glandular effector cell. At the synapse, the transmission of the nerve impulse takes place. This is initiated by a chemical discharge that causes an electrical current in the membrane of the presynaptic cell (sending cell). Then, once this nerve impulse reaches the end of the axon (the connection with the other cell), the neuron secretes a chemical compound called neurotransmitter that is deposited in the cleft or synaptic space (intermediate space between this transmitting neuron and the postsynaptic or receiving neuron). These secreted substances or neurotransmitters (noradrenaline and acetylcholine among others) are responsible for exciting or inhibiting the action of the other cell called postsynaptic cell.
The events are:
Acetylcholine is released into the synapse (5): Acetylcholine is a neurotransmitter that is released at synapses in response to a specific stimulus. The secreted neurotransmitter acts on specialized receptor sites on the postsynaptic cell, which causes changes in the metabolism of the postsynaptic cell, modifying its cellular activity. Ion channels bind the ligand and open (1): The channels control the transmission between neurons because they bind neurotransmitters and open in response to a ligand. So the neurotransmitters diffuse across the cleft and bidn to receptors.Na enters the postsynaptic cell, and the membrane potential changes (4): Sodium channels open and allow an inward diffusion of sodium ions (Na+) from the outside to the inside. This causes the membrane potential to become less negative or more positive or to approach the threshold potential. Next, this triggers an excitatory potential (EPSP) so it causes the postsynaptic membrane to depolarize and fire an action potential. which spreads along the membrane of the post-synaptic neuron. This means an impulse is transmitted.Acetylcholinesterase breaks down acetylcholine (3): Acetylcholinesterase is an enzyme that breaks down the neurotransmitter so it causes the inactivation of acetylcholine into acetic acid and choline. Na ion channels close (6): Na channels open and close according to different signals. The peak voltage causes them to close, and potassium channels open. So sodium ions stay inside the cell while potassium ions move outside of it. When this happens, repolarization (change in membrane potential that retunrs it to a negative value) takes place. Potassium channels remain open after the potential reaches the resting level causing hyperpolarization (the membrane potential becomes more negative) and it alters the ability of certain of ions to enter the cell. At the end, the cell has more K+ ions on the outside.Na is pumped out of the cell, and the membrane potential is restored (2): The sodium-potassium pump moves sodium ions to the outside and potassium ions to the inside.How are organisms in the kingdoms Fungi and Animalia similar?

A plant biologist is asked to develop strawberry plants with larger, sweeter berries. Through selective breeding, the biologist successfully produces the new strawberry plant.
What is one method the biologist can use to produce many identical strawberry plants of the same kind
Answer: Clonal progagation
Explanation:
Clonal propagation involves the production of identical individual without the fusion of germ cells. It can be multiplication through stem and other plants part such as leaves.
Strawberry as a fruits can be multiplied using the stems thus preventing the germ cells from genetic recombination that could lead to the formation of entirely new plants. It does not involve the union of male and female germ cells.

In an area where trees are growing taller, the giraffe population must adapt if it is to survive. Which statement BEST explains how the giraffes would be able to survive and reproduce?
F The genetic material for neck length within the offspring must mutate.
G The trait for longer legs would have to be a response to the change in the environment.
H The genetic material for smaller, shorter hind legs must exist within the giraffe population.
J The trait for longer necks must exist within the population and be inherited by the offspring.
Answer:
J. the trait for longer necks must exist within the population and be inherited by the offspring
Lamarckism was the theory was given by Lamarck and is based on physical changes. Giraffes would be able to survive when the traits of the long necks are inherited. Thus, option J is correct.
What is inheritance?Inheritance is the passing of the genetic material down the generation so that the beneficial traits that are essential for survival are passed from one generation to another.
When the trait essential for the giraffes to survive like long necks and legs are passed from one generation to another through reproductive methods then they will be able to survive.
Therefore, option J. trait for the longer neck must pass or be inherited by offspring.

What biome is Alabama in
Answer:
Deciduous forest biome
Explanation:
Deciduous forests are found in the following states in the U.S: Florida, Georgia, South Carolina, Alabama, Virginia, parts of Texas and Tennessee. Among the countries in Europe that have Deciduous forest biome include Italy, Spain, France, Bulgaria, Poland and much more.
Miss Emily's hometown in Alabama is the town in which William Faulkner's story "A Rose for Emily" is set, while Woodstock is a small community in Bibb County, Alabama. Despite the fact that the two places are distinct, there are a few similarities between them.
First and foremost, both towns are situated in Alabama, which means that they share a geographic location. Both towns are in the Deep South, a region known for its sultry climate, and both are located in rural areas. This implies that the two towns are exposed to comparable weather patterns and experience similar seasons throughout the year.
Second, both towns have a rich history, which is reflected in their architecture and cultural traditions. For example, Miss Emily's hometown has a beautiful but decaying old Southern mansion, which is symbolic of the town's former glory. Similarly, Woodstock, like many other small towns in the region, has numerous old homes and buildings that are over a century old.

1. explain how body plan and anatomy enables invertebrate to perform essential functions it needs to survive.
2. explain how body plan and anatomy enables chordate to perform essential functions it needs to survive.
3. explain how body plan and anatomy enables primate to perform essential functions it needs to survive.
Answer:
1)Invertebrates are known as creatures that do not have backbones. Even though these creatures do not have backbones, they have been uniquely designed in order to survive. According to studies, most of these creatures are found in the sea and one of them is the Star Fish or also called as the Sea Star. Starfish's functions and ability to survive is not the same like other animals which make them unique in a different way. The starfish's body is hard and bony for protection purposes and they exist in a variety of colors for camouflage. Their essential functions in order to survive are as follows:
-The Ability to Regenerate: Starfishes have the ability to grow damaged and lost limbs or even their entire body as long as the center part is still present and intact. And this is their way of reproduction as well.
-Having Tube Feet: Its arms are covered with a suction-like tiny cups of tube feet. This unique design of the starfishes enables them to move and secure themselves, especially on rocks and ocean floors.
-Unique Feeding Ability: Sea Stars don't have mouths nor teeth to ingest food. Rather, these creatures have the ability to push open or turn their stomachs out and digest its food. After digestion, their stomachs retract back to their bodies.
-Vascular System: How starfishes survive does not rely on having hearts, brains and blood. Rather, they use the seawater. The seawater serves as the one the circulates inside the sea stars' bodies and this is when nutrients and oxygen are being transported and absorbed.
2)Keep in mind invertebrates are those who have exoskeletons (outside skeleton) or are hydrostatic (no skeleton). This make up 95% of all animals for example an ant or sponge. For a sponge, all it has is tissues that enable it to allow water to flow out the tops.
Chordata are anything with vertebrates so a simple fish could suffice. THEY HAVE 4 SPECIFIC CHARACTERISTICS: 1.Notochord 2.Dorsal, hollow nerve cord 3.Pharyngeal slits 4.Muscual, an.al tail
This is us, we have thumbs, and vertebrates.
3)The bipedalism of primates puts their heads on a higher elevation and this allows them to see predators or prey from afar hence giving them advantage. Opposable thumbs on the hand and feet allow primates to grasp and handle objects effectively hence are able to make use of tools for hunting and etcetera
