The correct answers are: Archaea lack true peptidoglycan in their cell walls; The cytoplasmic membrane lipids of archaea have branched or ringform hydrocarbon chains.
The cell wall of all bacteria contains peptidoglycan. Archaeal cell walls do not contain this compound, though some species contain a similar one.
The Bacteria have membranes composed of unbranched fatty acid chains attached to glycerol by ester linkages. The Archaea have membranes composed of branched hydrocarbon chains attached to glycerol by ether linkages.
Answer:
There are 4 different fundamental states of matter: solid, liquid, gas, and plasma.
The atoms/molecules that make up a solid are packed <u>tightly</u> together and arranged in regular, repeating patterns. They are held firmly in place by their attractive forces and their <u>low kinetic energies</u> but do vibrate within a limited area. Solids, have a <u>fixed</u> shape and volume.
In liquids, the atoms/molecules have a moderate kinetic energy and flow easily around one another. They are kept from flying apart by attractive forces between them. Liquids have a fixed <u>volume</u> but assume the <u>shape</u> of their containers.
Atoms/molecules in gases fly in all directions at great speeds. Due to this <u>high</u> kinetic energy, attractive forces between them are <u>insignificant</u>. Gases assume the volume and shape of their containers.
Lastly, plasma is the state of matter with the highest thermal energy. It is made up of free electrons and the positive ions from which they came. The electrons freely move around within this system of positive ions in a similar way to <u>gases</u> . Plasmas are strongly influenced by electric and magnetic fields due to the charged particles.
Answer:
p=0.9
Explanation:
The frequency of the different genotypes is as follows:
- AA = 0.81
- Aa = 0.18
- aa = 0.01
There are 2 alleles for this gene, the dominant allele <em>A</em> appears twice in the homozygous dominant genotype and once in the heterozygous.
Then, the frequency of the <em>A </em>allele, <em>p</em>, can be calculated as:
p= freq(AA) + freq(Aa)/2
p= 0.81 + 0.18/2
p=0.9
A native species is a species that is born in an environment. Introduced species are species that are brought into an environment from other ecosystems. For Example the Pythons in south Florida
An object is in motion if its distance relative to another object is changing. To tell if an object is moving, you use a reference point. If an object's distance from another object [reference point] is changing. A place or object used for comparison to determine if something is in motion.
I'm not too sure if this is what you needed go know, I hope it helped
