Quade is studying for an exam, which will cover neurons and action potentials. He has drawn a diagram that shows the segments of an axon, and he has noted that every time a segment fires, the _____ flood in from the outside of the cell, while the prior segment returns to its resting potential. Please choose the correct answer from the following choices, and then select the submit answer button.
Answer: positive sodium ions
Explanation:
This relates to the Action Potential which is what a nerve cell goes through when it needs to send information down the nerve cell to another cell and so on till it gets to the destination of the message.
The information is transmitted when the segments of the axon fire and when they do, positive sodium ions come in from outside the cell to the inside thereby making the inside positive. The previous segment would return to a resting potential when potassium ions which are negative, rush into the cell.

What are chromosomes?
Answer:Chromosomes are thread-like structures found within the nucleus of both animal and plant cells. Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA). DNA is passed along from parents to children and carries the precise instructions that distinguish each living thing.
The word "chromosome" is derived from the Greek terms "chroma" and "body" (soma).

Why do plants need water, light, and carbon dioxide?
Answer;
these are used in photosynthesis altogether. light splits the water into hydrogen and oxygen. water is used to manufacture starch, soften the testa during germination, dissolve food as well. carbon dioxide is also used during photosynthesis.
Deforestation occurs when large Amounts of trees are cut down and not replaced which of the following would result from deforestation
A. Decrease carbon in the atmosphere
B. Increased carbon in the atmosphere
Answer:
The correct answer is (B).
Explanation:
Deforestation occurs when large Amounts of trees are cut down and not replaced, which of the following would result from deforestation...
Increased carbon in the atmosphere
This statement is true because when trees become less abundant, the amount of oxygen being released into the atmosphere by trees via photosynthesis.
The circumstance that would result from deforestation is the increased carbon in the atmosphere. Thus, the correct option is B.
What is Deforestation?Deforestation may be defined as the process of cutting down or eliminating trees in large numbers from our surroundings. This activity generally happens due to industrialization, wood extraction, urbanization, etc.
When the number of trees remains less in the environment due to deforestation or any other activity, the level of carbon dioxide in the atmosphere typically rises.
This is because carbon dioxide is considered the reactant of photosynthesis that is utilized by the plants along with water in the presence of sunlight and converted into oxygen.
But when the number of plants decreases, the level of carbon in the atmosphere increases, and the level of oxygen in the atmosphere decreases.
Therefore, the circumstance that would result from deforestation is the increased carbon in the atmosphere. Thus, the correct option is B.

What is a pioneer species? (Will give brainiest)
Answer:
The first species to colonize an ecosystem that is previously damaged or disrupted. Supplement. Pioneer species is the first to colonize an ecosystem previously disturbed or damaged. For example, sand that has become barren is colonized by a pioneer species of lyme grass (Leymus arenarius)
Explanation:
A scientist is comparing the sequences of related genes among three species. Two of the species have very similar sequences, while the sequence of the third species differs greatly from the others. T
Hi. The question you presented above is incomplete. This makes it impossible for this question to be answered. However, when searching for your question on the internet, I was able to find another question exactly like yours, which asked you to explain the evolutionary relationship between these three species. If that's the case for you, I hope the answer below will help you.
In a simplified way, we can infer that among the three species presented above, the third presented a faster evolution than the first two and this is what explains the difference between the gene sequences between the species. As the question presents, the three species have related genes, which indicates that they had a common ancestor, however the difference in the gene sequence of the third species shows that it evolved first, showing changes that cannot be noticed in the first two species that are evolving more slowly.
SO you hopefully selected that an Allele is a form of a gene. BUT what is this really...
A. an allele is a protein that causes hair no hair in the guinea pig
B. an allele is a length of DNA with a specific sequence of nitrogen bases that make a protein that results in Hair or No Hair on the guinea pig
Answer:
B. an allele is a length of DNA with a specific sequence of nitrogen bases that make a protein that results in Hair or No Hair on the guinea pig
Explanation:
An organism that has two different alleles of the gene is called heterozygous. Phenotypes (the expressed characteristics) associated with a certain allele can sometimes be dominant or recessive, but often they are neither.
B. an allele is a length of DNA with a specific sequence of nitrogen bases that make a protein that results in Hair or No Hair on the guinea pig

The dichotomous key below provides a way to classify some animals into groups according to their physical characteristics. The key can be used to classify each of the four animals represented below. Which answer choice shows the correct classification group for each animal? 1. Wasp = group D; Ant = group D; Tiger = group A; Bird = group B 2. Wasp = group B; Ant = group A; Tiger = group D; Bird = group C 3. Wasp = group B; Ant = group D; Tiger = group A; Bird = group C 4. Wasp = group D; Ant = group A; Tiger = group A; Bird = group B
Complete question:
The dichotomous key below provides a way to classify some animals into groups according to their physical characteristics.
Dichotomous Key
I wings------------------go to II
no wings------------- group A
II feathers---------------group B
no feathers----------go to III
III two legs------------- group C
six legs---------------group D
The key can be used to classify each of the four animals represented below ⇒ wasp, ant, tiger, bird
Which row in the chart shows the correct classification group for each animal?
Row Wasp Ant Tiger Bird
(1) group D group D group A group B
(2) group B group A group D group C
(3) group B group D group A group C
(4) group D group A group A group B
Answer:
Row Wasp Ant Tiger Bird
(4) group D group A group A group B
Group A: Tiger and Ant → They do not have wingsGroup B: Bird → It has wings and feathersGroup D: Wasp → It has wings, does not have feathers, and has six legsExplanation:
When analyzing a dichotomous key, you just need to pay attention to the given descriptions and carefully observe the organisms you have.
The key describes specific morphological traits of each organism that are useful to differentiate it from other organisms. So all you need to do is to follow the instructions given in each step, and the key will guide you directly to the answer.
In the exposed example you have four organisms: wasp, ant, tiger, bird
The provided key gives you three steps: I, II, III.
Step I:
wings------------------go to II
no wings------------- group A
Here the key tells you to separate, from your group of organisms, the ones that have wings from the ones that do not have wings.
wasp and bird have wings → So you need to go to step IItiger and ant do not have wings → So they belong to Group AStep II:
feathers---------------group B
no feathers----------go to III
Now you only need to consider the bird and the wasp, which are the two organisms that have wings.
Here the key tells you to separate the one that has feathers from the one that does not have feathers.
Bird has feathers → So it belongs to the group BThe Wasp does not have feathers → So you need to go to step IIIStep III:
two legs------------- group C
six legs---------------group D
In this last step, the key takes you to two possible groups. But you only have one left organisms, which is the wasp. So what you need to do is to observe how many legs your wasp has. It is an insect, so it has six legs. The wasp belongs to Group D.
You do not have any organism that belongs to group C.
To sum up, according to the given information you could group the group of organisms as follows:
Group A: Tiger and Ant → They do not have wingsGroup B: Bird → It has wings and feathersGroup D: Wasp → It has wings, does not have feathers, and has six legswhat is photo synthesis?
