Fungi join bacteria as the primary decomposers in different ecosystems. They feed on the organic remains of dead plants. They release special enzymes that break down lignin, a structurally complex substance in wood. Decomposing organic matter is considered by ecologists as the major ecological role of fungi.

Identify how the deletion of a single nitrogen base in DNA can cause a harmful mutation in an organism.
ra1l [238]

Answer:

B. Nearly every amino acid translated after the error will create the wrong protein after the deletion of a base.

Explanation:

Generally, mutations occur in two ways: 1) a base replacement, where one base is replaced for another; 2) insertion or deletion, where a base is either incorrectly inserted or deleted from a codon.

When a nucleotide is wrongly inserted or deleted from a codon, the effects of this change can be extreme. An insertion or deletion can affect every codon in a particular genetic sequence.  For example, given the code:

GAU GAC UCC GCU AGG. It is the codes for the amino acids aspartate, aspartate, serine, alanine, and arginine. If the A in the GAU were to be deleted, the code would become GUG ACU CCG UAG G. It won't produce any right amino acid.

So, if the code becomes changes, it won't produce any amino acid or will produce the wrong amnio acid.

Diffusing molecules move ________ until they are ________. Through channels of active transport proteins; evenly distributed up
koban [17]

Answer;

-Down the concentration gradients; evenly distributed

Diffusing molecules move down the concentration gradients until they are evenly distributed.

Explanation;

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.

-Whenever a substance exists in greater concentration on one side of a semipermeable membrane, such as cell membranes, any substance that can move down its concentration gradient across the membrane will do so. If the substances can move across the cell membrane without the cell expending energy, the movement of molecules is called passive transport.

-The mechanism of molecules moving across a cell membrane from the side where they are more concentrated to the side where they are less concentrated is a form of passive transport called simple diffusion.

The various taxonomic levels (e.g. genera, classes, etc.) of the hierarchical classification system differ
Westkost [7]

Answer:

(c) their inclusiveness.

Explanation:

The taxonomic classification has eight levels, they go from the more inclusive to the more exclusive.

The eight categories are: <u>Domain</u> which  is the most inclusive level, that is to say, that the largest number of individuals are included in this level. There are  three domains according to the cells types, and where they live. They are the Eukarya, Bacteria and Archaea. Domains are divided into <u>kingdoms</u>, they are the Plantae, protista, Eubacteria, Archaebacteria,  Animalia and Fungi. After kingdoms the <u>Phylum</u> category comes, following Phylum is <u>Class</u>, various classes that are related will form a Phylum. The next category is <u>Order</u>, order is divided into <u>Family,</u> families are broken into <u>Genus</u>, where species are closely related between each other and finally the last category is <u>Especies identifier,</u> in this group there are unique characteristics that will identify a specie. With this classification we can see that we go from global groups  to more specifics ones as the classification avances.
