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 legsSO 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
Answers
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.

The arrows in a food chain show: a Who eats who b Heat energy being lost c The movement of energy between organisms d The route of food to the shops
Answers
Answer:
c The movement of energy between organisms
Explanation:
Pyramid of energy is a model used to depict the flow of energy from one trophic level or feeding level to the next in an ecosystem. It's a diagram that compares the energy used by organisms at each trophic level of the food chain. The pyramid of energy must never be inverted or turned upside down.
The units used in the construction of pyramids of energy is kilocalories (kcal) or energy per area per time (Jm-²year-¹).
This ultimately implies that, the arrows in a food chain show the movement of energy between organisms such as from producers which are autotrophs or self-feeders such as plants to the tertiary consumers.
Furthermore, a list of the types of organisms in an eco pyramid are;
I. Producers: these are autotrophs or self-feeders such as plants.
II. Primary consumers: these are herbivores that typically feed on plants such as a goat or deer.
III. Secondary consumers: these consists of carnivores that typically feed or eat flesh such as lion, tiger, cheetah, etc.
IV. Tertiary consumers: these are higher predators such as humans that aren't normally fed on by other organisms in the ecosystem.
Answer: The arrows in a food chain show (The movement of energy between organisms). The correct option is C.
Explanation:
In an ecosystem, a food chain shows the transfer of energy and nutrients ( food) from organisms to organisms in a feeding pathway. Instead of giving functional group names such as primary producer, primary consumer and so on, in a good chain, the organism at each step is identified. Thus,
Grass-------> Zebra ---------> lion
(Primary (Primary ( secondary
producer). consumer) consumer)
this is an example of a simple food chain in a grassland ecosystem. This ARROWS represented above shows the direction of energy flow through an ecosystem.
Furthermore, the grass traps solar energy and stores it as chemical energy in the food made during photosynthesis. When eaten by Zebra, which is the primary consumer, the energy stored in the grass is transferred to the consumer. This transfer is inefficient as some of the stored chemical energy is lost as heat. When the zebra is eaten by a Lion,which is the secondary consumer.

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.
Answers
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.

С
The change in amino acids shortens the polypeptide sequence.
D
The alternation of a single nucleotide encodes for a different amino acid.
Answers
Answer:
A . The entire sequence of amino acids is changed.
Explanation:
The entire sequence of amino acids is changed when the mutation occurs in the protein because amino acid is the building block from which protein is made. Mutation is the sudden change that is occur in the genetic makeup i.e. DNA when the cell is exposed to radioactive radiation of chemicals. So due to this change, the sequence of amino acids changed and they work differently.
