A scientist is studying three different plant species that appear to be closely related. All three are found in a wide variety of environments and are very similar in appearance. Which of the following would provide the best evidence regarding the evolutionary relationship of these three species?
Comparing the different climates in which the species can be found
Comparing the genomes of each species to see which are most similar
Determining whether the plants are capable of both sexual and asexual reproduction
Determining which types of animals eat each species
Determining the genomes of each species to see which is similar will provide the best evidence regarding the evolutionary relationship of these species. So the correct option is B.
What are evolutionary relationships?The relationships of different species with each other based on their history of evolution are called evolutionary relationships.
The study of the relationships between organisms by categorizing them into various kinds of groups is called systematics.
All the species of organisms, from bacteria to mammals have evolved from some kind of ancestral species by the process of evolution.
Determination of these evolutionary relationships is the key to understanding the process of evolution. Evolutionary relationships are determined by using evolutionary trees which are diagrammatic representations of ancestral species and their descendants.
The study of genomics to identify the similarity between organisms is yet another useful tool to determine the relationship between them.
Therefore the correct option is B.

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.

At Weeks Bay there was a population of 200 alligators. In May of 2006 a new species of catfish was released into the Mississippi. These catfish reproduce very fast and soon become a rich food source for the alligator population. This provides the alligators with the energy needed for more successful reproduction. The following summer of 2007, 100 babies were born and a total of 40 gators died that year. However, the next year in early 2008 there was a terrible drought, causing 100 alligators to die.

Explanation:
A denisty of a bottle weighs 0.25N when empty & 0.75N when filled with water & 0.65N when filled with alcohol. Calculate;. 1) the volume of the bottle 2) the denisty of the alcohol (denisty of water is 1000kg/m & g is 10m
Answer:
[tex]0.05\times 10^{-3}\ \text{m}^3[/tex]
[tex]800\ \text{kg/m}^3[/tex]
Explanation:
[tex]W_b[/tex] = Weight of bottle = 0.25 N
[tex]W_w[/tex] = Weight of water = [tex]0.75-0.25=0.5\ \text{N}[/tex]
g = Acceleration due to gravity = [tex]10\ \text{m/s}^2[/tex]
[tex]\rho_w[/tex] = Density of water = [tex]1000\ \text{kg/m}^3[/tex]
Mass of water
[tex]m_w=\dfrac{W_w}{g}\\\Rightarrow m_w=\dfrac{0.5}{10}\\\Rightarrow m_w=0.05\ \text{kg}[/tex]
Volume is given by
[tex]V_w=\dfrac{m_w}{\rho_w}\\\Rightarrow V_w=\dfrac{0.05}{1000}\\\Rightarrow V_w=0.05\times 10^{-3}\ \text{m}^3[/tex]
Volume of the bottle is [tex]0.05\times 10^{-3}\ \text{m}^3[/tex].
This means that the alcohol will take the same amount of volume.
[tex]W_a[/tex] = Weight of alcohol = [tex]0.65-0.25=0.4\ \text{N}[/tex]
Mass of alcohol
[tex]m_a=\dfrac{0.4}{10}\\\Rightarrow m_a=0.04\ \text{kg}[/tex]
Density is given by
[tex]\rho=\dfrac{m_a}{V_w}\\\Rightarrow \rho=\dfrac{0.04}{0.05\times 10^{-3}}\\\Rightarrow \rho=800\ \text{kg/m}^3[/tex]
Density of alcohol is [tex]800\ \text{kg/m}^3[/tex]
The volume of the bottle is 50 mL and the density of alcohol is 0.8 g/c[tex]m^{3}[/tex]
The weight of empty bottle is 0.25N
the weight of bottle filled with water is 0.75N
therefore, the weight of water in the bottle is 0.75N - 0.25N = 0.50N
we know that weight, w =mg , where m is the mass of substance and g is acceleration due to gravity. Here we will take g= 10 m/[tex]s^{2}[/tex] for simplicity.
⇒ m = w/g = 0.5/10 = 0.05 kg
⇒ mass of water is 50g
now, the density of water ρ(w) = 1g/[tex]cm^{3}[/tex] = 1g/mL
relation between mass, density and volume is:
V = m/ρ = 50/1 = 50mL
Hence the volume of the bottle is 50mL.
Now it is given that the weight of bottle filled with alcohol is 0.65N
⇒ weight of alcohol = 0.40N
⇒ mass of alcohol = 0.40/g = 0.40/10 = 0.040kg = 40g
The volume of the bottle remains the same, so to calculate the density of alcohol we use the above mentioned relation between mass, density, and volume on alcohol.
That is, V = m/ρ
⇒ ρ(al) = m/V = 40/50 g/c[tex]m^{3}[/tex]
ρ(al) = 0.8 g/c[tex]m^{3}[/tex] or 0.8 g/mL

Neurons make up the communication network in your body called ______
Answer:
Nerve Cells
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.In some carnations, red is co-dominant with white.

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.
