The dichotomous key is a classification tool based on morphological characteristics. The correct option is B. Dichotomous keys can only be used to classify organisms based on their observable traits.
What is a Dichotomous key?A dichotomous key might be considered a significantly useful tool to classify organisms.
The key provides an easy and fast way for identification by describing different morphological observable traits, leading you to the correct taxonomic classification.
The term dichotomous refers to how information is provided. You will always have two options (a and b, or 1 and 2), and you will have to choose one of them according to the characteristics of your organism.
Each time you choose an option, it leads you to the following description, which gets more specific each time.
Probably you might need an atlas or a dictionary to understand some of the technical terminologies.
You will also need to carefully observe your specimen, to get to distinguish different traits. If the specimen is too small you might need a loup.
The correct statement is B. Dichotomous keys can only be used to classify organisms based on their observable traits.

Which abiotic factor is necessary for animals to survive in an aquatic
ecosystem?
Answer:
It's Oxygen.
Explanation:
Some abiotic factors, such as oxygen, are important in aquatic ecosystems as well as terrestrial environments. Terrestrial animals obtain oxygen from the air they breathe. Oxygen availability can be an issue for organisms living at very high elevations, however, where there are fewer molecules of oxygen in the air.

Answer:
Explanation:
Hydrogen cyanide (HCN)
The molecular geometry of HCN is linear. The compound is polar in nature.
As Carbon is bonded to two atoms, it follows the molecular geometry of AX2. And as per VSEPR theory, molecules covered under AX2 have a linear molecular geometry.
Hence Hydrogen Cyanide has linear molecular geometry.
Which of the following is an extremely dense form of connective tissue?
Answer:
the breast tissue
Explanation:
Tendons and Ligaments are the extremely dense form of connective tissue.
What are dense connective tissues?Dense connective tissue is also known as dense fibrous tissue which is a form of connective tissue composed mostly of fibers. These fibers are made of type I collagen which are rows of fibroblasts, the fiber-forming cells that make up the fibers, filled in between the collagen strands.
Tendons and ligaments are strong, rope-like structures which is formed by dense connective tissue where tendons connect skeletal muscles to bones, while ligaments connect bones at joints.
Ligaments have more elastic fibers which are more extensible than tendons. This connective tissue is found in the lower layers of the skin known as Dermis, where it is structured in sheets.
Thus, Tendons and Ligaments are the extremely dense form of connective tissue.

C. 0.9420/s north
d. 56.67 m/s north
e. 1.34 m/s north
f. 0.56 m/s north
[tex]\\ \sf\longmapsto Avg\: Velocity=\dfrac{Total\: displacement}{Total\:time}[/tex]
[tex]\\ \sf\longmapsto Avg\: Velocity=\dfrac{6800}{7200}[/tex]
[tex]\\ \sf\longmapsto Avg\: Velocity=0.9420m/s[/tex]
Answer:
0.9420m/s north
Explanation:
Given,
Displacement (Total) = 6800 metres(m)
Time = 2 hours
We need to convert hours to seconds.
2 hours = 7200 seconds
We know,
[tex]\sf\longmapsto \: Average \: velocity = \frac{Total \: Displacement}{Total \: time} [/tex]
Let's start solving!
[tex]\sf\longmapsto \: Average \: velocity = \frac{6800 \: metres}{7200 \: seconds} [/tex]
[tex]\sf\longmapsto \: average \: velocity = 0.9420\: m/s[/tex]
if a red plant is crossed with a white plant and the offspring is pink, what is it called ?
Answer:
Incomplete dominance is an example of a non-mendelian trait (doesn't follow the genetic rules established by Gregor Mendel). When two parents mate and produce offspring, the offspring is a blend of the two parents. So, a red flower and a white flower would make a pink flower.
What are the four different variations of bacteria?

Answer:1).A nonrenewable resource is a natural substance that is not replenished with the speed at which it is consumed. It is a finite resource.
2)Rocks are made of minerals, like quartz, calcite, feldspars, and micas. Most rocks are made from more than one mineral, but there are quite a few kinds that are made from only one mineral. Minerals are not rocks, rocks are made of minerals.
3)Coal is a very useful rock that formed over millions of years from the ... No, coal is not a mineral because coal is made of dead plants.
4)The relatively cheap cost of fossil fuels is a major positive aspect. They are in abundant supply, which makes them inexpensive to drill or mine for. In particular, coal is one of the most widely available fossil fuels.
5)High initial costs for material and installation and long ROI (however, with the reduction in the cost of solar over the last 10 years, solar is becoming more cost feasible every day) Needs lots of space as efficiency is not 100% yet. No solar power at night so there is a need for a large battery bank.
