When the particles are equally spaced apart they have reached:
A. Hypertonicity
B. Dynamic Equilibrium
C. Homeostasis
D. Osmolarity
Answer:
B. Dynamic Equilibrium
Explanation:
Since the molecules are still in motion, but an equilibrium has been established, the end result of molecular diffusion is called a "dynamic equilibrium". The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane. At equilibrium, the movement of molecules does not stop.
Answer:
B. Dynamic Equilibrium
Explanation:
When the particles are equally spaced apart they have reached the dynamic Equilibrium.

Multicellular eukaryotes that have cell walls and are heterotrophic. _______________________[Text Wrapping Break] f. Multicellular eukaryotes that have cell walls and are autotrophic. ________________________
Answer:
A. Unicellular prokaryotes that live in dust. Monera.
B. Unicellular eukaryotes that line in pond water. Protist.
C. Multicellular eukaryotes that live all over the planet and consume food. Animals.
D. Unicellular prokaryotes that live in volcanic ash. Monera.
E. Multicellular eukaryotes that have cell walls and are heterotrophic. Fungi.
F. Multicellular eukaryotes that have cell walls and are autotrophic. Plants.
Explanation:
The 5 kingdoms are a way of classifying all living organisms on our planet, as each species inside a kingdom shares similarities with the other species in it.
Monera kingdom includes all of the prokaryotic organisms that exist, which includes bacteria and archaea. These beings are characterized by lacking a nucleus and membrane-bound organelles and having one single circular chromosome that is found in the center of the cell. They are unicellular. Example: escherichia coli.
Protists are the most primitive eukaryotes that exist, most of them are unicellular and microscopic, but possess a nucleus and specialized organelles like the rest of the eukaryotes have. Example: yeasts.
Fungi and Plants are quite similar, they are multicellular eukaryotes that have cell walls. Their main difference relies on the way they obtain nutrients: fungi are heterotrophs, they feed off living things; plants, however, are autotrophs and realize photosynthesis (they do not need to feed). Fungi and Plants also reproduce differently: fungi reproduce through spores; plants can reproduce sexually or asexually. Fungi example: amanita; plant example: cactus.
Animals are multicellular eukaryotic organisms that reproduce sexually and are heterotrophs (some feed off plants, some feed off other animals). They are characterized by their ability to move. Example: horse.

The offspring in binary fission are
identical
different
Answer:
Identical
Explanation:
Binary fission is a form of asexual reproduction. This is when only one parent is involved in creating offspring. Since there is only one parent, two sets of DNA cannot be combined into a new offspring; so, it must be identical.

PLEASE ANSWER THE QUESTION BELOW
Answer:
Explanation:
A diagram of a Punnett Square showing the chromosomes involved in the inheritance of sex-linked traits.
The female had the genotype XHXh, and produced the two gametes seen at the left side of the diagram.
The male had the genotype XHY0, and produced the two gametes seen at the right side of the diagram.
The genotypes seen in the center of the square represent the possible genotypes of the F1 generation.
Two female offspring are produced for every two male offspring.
One male and one female offspring inherit normal genes.
One female is heterozygous for the hemophilia trait and is considered a carrier.
One male receives a damaged X-chromosome and inherits the condition known as hemophilia.

Explain why DNA Sequencing proves that all species have a common ancestor
Answer:
Below
Explanation:
The reason why we can conclude that all species have common ancerstory is that all the species have several same base pairs. Here are a few listed:
