How are cladistics and cladograms related? + Example - Socratic
Nov 11, 2017 · A cladogram is a diagram used in cladistics to show how organisms are related to one another. A cladogram is a diagram used in cladistics to show how organisms are related to one another. Cladograms are constructed so that there are as few changes from one organism to the next as possible. An example of a cladogram is shown below. Remember, cladistics is a method of classifying organisms that ...
Protists - Biology - Socratic
May 20, 2018 · Explanation: Protoctista is a kingdom in the taxonomic hierarchy that falls under the Eukarya domain. They are mostly unicellular but some are multicellular such as algae and seaweed. They share the same characteristics as eukaryotic cells; 80s ribosomes, membrane bound organelles including a nucleus etc. Most protoctists are autotrophic (make ...
What do the "nodes" in a cladogram represent? - Socratic
Feb 2, 2017 · The nodes in cladograms represent divergences or speciation events. Explanation: The nodes on the trees indicate the common ancestors of descendants. At each node a splitting event occurs. The node therefore represents the end of the ancestral taxon and the stems , the species that split from the ancestor. The two taxa that split from the node ...
Cladistics - Biology - Socratic
A cladogram is a phylogenetic tree that concentrates on branches stemming from common ancestoral lines.
How would you compare cell organelles to parts of a car?
Sep 23, 2016 · Specialised organelles; Cell wall : Chassis (tough outer shell that provides protection) Chloroplasts : Solar panels (convert solar energy into energy for the cell / cars features) Flagellum : Spoilers (behind the body of the cell, related to speed - even though spoilers are more for downforce etc.) Answer link.
How do you integrate x^2(sinx)dx? - Socratic
Jul 26, 2016 · Explanation: Use integration by parts, which takes the form: ∫udv = uv − ∫vdu. For ∫udv = ∫x2sin(x)dx, we let: u = x2 ⇒ du dx = 2x ⇒ du = 2xdx. dv = sin(x)dx ⇒ ∫dv = ∫sin(x)dx ⇒ v = − cos(x) Thus, substituting these into the integration by parts formula, we see that: ∫x2sin(x)dx = −x2cos(x) − ∫(− 2xcos(x))dx ...
Percent Concentration - Chemistry - Socratic
Percent concentration by mass is defined as the mass of solute divided by the total mass of the solution and multiplied by 100%. So, #c% = m_ (solute)/ (m_ (solution)) * 100%#, where. #m_ (solution) = m_ (solvent) + m_ (solute)#. There are two ways to change a solution's concentration by mass. Adding more solute - making the solution more ...
How do you integrate csc^3x? - Socratic
Aug 19, 2016 · Explanation: We have: I = ∫csc3xdx. We will use integration by parts. First, rewrite the integral as: I = ∫csc2xcscxdx. Since integration by parts takes the form ∫udv = uv −∫vdu, let: {u = cscx ⇒ du = −cotxcscxdx dv = csc2xdx ⇒ v = − cotx. Applying integration by parts:
Isotope Notation - Chemistry - Socratic
Isotope notation, also known as nuclear notation, is important because it allows us to use a visual symbol to easily determine an isotope's mass number, atomic number, and to determine the number of neutrons and protons in the nucleus without having to use a lot of words. Additionally, N = A −Z. Example 1: What is the isotopic notation for ...
Integration by Parts - Calculus - Socratic
Integration by Parts is like the product rule for integration, in fact, it is derived from the product rule for differentiation. It states #int u dv =uv-int v du#. Let us look at the integral #int xe^x dx#. Let #u=x#. By taking the derivative with respect to #x# #Rightarrow {du}/ {dx}=1# by multiplying by #dx#, #Rightarrow du=dx#. Let #dv=e^xdx ...
