Question:
Use the following dichotomous key to identify an irregular blue flower with five petals and a fruit that is a ripened flower ovary or follicle.
Dichotomous Key of Ranunculaceae
#1.
a. Fruit is a group of alkenes.............................. go to step 2
b. Fruit is a group of follicles..............................go to step 4
#2.
a. Petals are not present.....................................go to step 3
b. Petals are present............................................Ranunculus
#3.
a. The flower has 4 sepals.................................. Clematis
b. The flower has 5 sepals................................... Anemone
#4.
a. The flowers are regular..................................... Aquilegia
b. The flowers are irregular................................... Delphinium
The flower is a: A. Anemone B. Clematis C. Delphinium D. Ranunculus
Answer:
The species belongs to Delphinium genera.
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.
In the example, we have a plant species with irregular blue flowers and five petals. The fruits are a ripened flower ovary or follicles.
Irregular flower: Term that refers to asymmetrical flowers that only have one plane. Follicle: Term that refers to dry dehiscent fruits originated from a flower with only one carpel. When mature, they open by the ventral suture.So, let us begin, step by step. For each number, we are going to have two options (a and b). By knowing our organism, we need to decide which one is correct and follow indications.
#1.
a. Fruit is a group of alkenes.............................. go to step 2.
b. Fruit is a group of follicles..............................go to step 4.
We know that our fruit is a follicle. Option a is not correct (it is not a group of alkenes). Option b is the correct one. Knowing this, we must go to step four. ***Note: In the hypothetical case that the fruits were a group of alkenes, and option a was correct, we should go to step two, as indicated***.
#4.
a. The flowers are regular..................................... Aquilegia
b. The flowers are irregular................................... Delphinium
We know that our flower is an irregular one. So the correct option is b. This option leads us to Delphinium genera. Our species belongs to this taxonomic group. ***Note: In the hypothetical case that the fruit was actually a regular flower, and option a was correct, our species would belong to Aquilegia genera***

A certain mutation in the gene for hemoglobin results in the red blood cells becoming sticky,
rigid, and irregularly shaped. These irregularly shaped red blood cells block the flow of blood
throughout the body. A single base mutation is responsible for these irregularly shaped blood cells.
Which of these mutations most likely results in the mutated hemoglobin gene?
F. Insertion
G. Deletion
H. Duplication
J. Substitution
Answer:J
Explanation:Substitution
Mutation in genes can result in different types of abnormalities. In gene related to hemoglobin makes RBCs sticky, irregular shaped, this is because of substitution.
What is substitution?Mutation is a type of replication error during formation of new DNA.
In substitution mutation, incorrect nucleotide is placed at incorrect position during DNA replication, a point mutation occur in which a single nucleotide is substituted.
It actually does not add or remove any nucleotide from the sequence, just it substitute it.
In gene related to hemoglobin, the amino acid glutamic acid gets replaced with the valine amino acid at position 6 in beta-globin, which results in sticky, irregularly shaped red blood cells.
Thus the correct option is J.

O Analyze the patient's family history regarding heart disease
O Analyze the patient's diet to quantify cholesterol intake
O Determine the exact amount of cholesterol in the patient's blood
O Determine if the cholesterol will lead to high blood pressure
Answer:
Analyze the patient's diet to quantify cholesterol intake
Explanation:
This is because since the patient family consumed more of red meat, it should be analysed. Because researches find out that red meat either processed or unprocessed contain more protein than fish, milk, and it can raise cholesterol levels. Red meat contain high cholesterol and increaee in cholesterol levels can lead to coronary heart diseases.

The phylogenetic tree shown shows the evolutionary relationships among finches
What can be concluded from this diagram?
A. Warbler finches and cactus finches are the most closely related.
B. Tree finches and warbler finches are the least closely related.
C. No finches have a common ancestor.
D. Tree finches and cactus finches have a common ancestor.
The phylogenetic tree shown shows tree finches and cactus finches have a common ancestor. So, the correct option is D.
What is Phylogenetic tree?A branching diagram that depicts the evolutionary relationships between a set of creatures, species, or genes is called a phylogenetic tree, sometimes referred to as an evolutionary tree. On the basis of the similarities and contrasts in their physical or genetic traits, it depicts the evolutionary history of these groups.
We can draw the conclusion that cactus and tree finches are more closely connected to one another than they are to any other finch species on the tree. The diagram does not indicate if tree finches and warbler finches are more or less closely related to one another, or whether cactus finches and warbler finches are.
Therefore, the correct option is D.

what ways do we use patterns of classification in science? give examples
Answer:
Classification is the way scientists use to categorize and organize all of life. It can help to distinguish how similar or different living organisms are to each other
Explanation:
Patterns are used in science to classify objects or phenomena into groups. There are patterns of both similarity and difference.
What is classification?Classification is the way scientists use to group and categorize objects, phenomenon or life forms. It can help to distinguish how similar or different living organisms are to each other based upon the pattern of their structure and organization.
Patterns are regular and intelligible forms , sequences, or structure that found throughout nature. Scientific questions may be generated when scientists observe a pattern of events or when something does not match an established pattern.
For example, the frozen water in an iceberg is arranged into a regular, repeating crystal structure—a pattern of similarity. Young children can observe a common pattern of difference, the differences between adult animals and their offspring.
Thus, it is clear from above explanation, the ways to use patterns of classification in science.
