The correct statement describing environmental consequence of unsealed Landfills is : ( A ) Landfills can produce carbon dioxide that leak into the atmosphere

A landfill is composed of 4 essential components and some are ;

  • bottom linear
  • hydrogeologic component and
  • A cover ( seal )

Given that a landfill constitutes of about 40 to 60 percent of C0₂ the environmental consequence of not providing a proper seal for the landfill will be the leakage of C0₂ into the atmosphere. while

The release of Heavy metals as leach ate into the surrounding can be controlled with the provision of a system in the landfill, materials in landfill undergo decomposition for a long period of time.

Hence we can conclude that Landfills can produce carbon dioxide that leak into the atmosphere.

max2010maxim [7]

(You will find the cladogram in the attaches files)

Answer:

C. The genomes of species C and D are nearly identical because neither species has a derived character.  

Explanation:

A Cladogram is a<em> tree-type graph</em> based on <em>cladistic analysis</em>. It represents the common ancestral relationships among the involved groups.

  • The tree-type graph is a ramified diagram that represents the relationship between the involved taxa.
  • The cladistic analysis follows the maximum parsimony criterium. Explains the character state from the point of view of the fewest changes through history. Explains evolution with the minimal amount of evolutive changes. It recognizes the monophyletic groups as natural groups. These groups are the clades, and their classification -<em>sequencing</em>- represents their phylogeny.
  • The<em> sequencing</em> term refers to lists of groups according to their relation. One group is the brother-group of the following one.

So the cladogram represents the relationship between groups according to a derived character.

The derivated character is any trait that a group passes to the descendants. Through evolution, the characters change, and new changes are added. When referring to a derivate character, we mean that all the subsequent species in the cladogram carry the trait.

A cladogram provides an image of how new species keep characters that were inherited from older species.  

So, in the exposed example, the five dots represent derived characters, representing traits 1 to 5. Branches A to F, represent groups. (See the cladogram in the attached files). Group A inherited trait 1, group B probably still carries trait 1, but also trait 2. Groups C and D equally inherited trait 3. Group E inherited character 4, and finally, group F inherited character 5.

Groups C and D inherited trait 3 and probably also still have traits 1 and 2. So they are very similar to each other. At a certain point, they diverged, probably due to a new mutation that was not passed to the rest of the group.  

C. The genomes of species C and D are nearly identical because neither species has a derived character. Correct.

Distinguish between voluntary and involuntary actions.

<h2>GREETINGS!</h2><h2>_____________________________________</h2>

<u>ANSWER</u><u>:</u>

<h2><u>DEFINITIONS</u></h2><h2>_____________________________________</h2><h3><u>VOLUNTARY MUSCLES:</u></h3>

Voluntary muscles are those muscles which work under our conscious control and can be controlled at will also we can choose choose them when to use and when not to use. These are simply SKELETAL MUSCLES attached to the bone, so all the movements of hand and legs and whatever u do are because of voluntary muscles.

<h3><u>__________________________________________________</u></h3><h3><u>INVOLUNTARY MUSCLES:</u></h3>

the muscles in the human body that do not work under our will and we cant control them. They are mainly controlled by the autonomic nervous system in the body. So, involuntary muscles include all the muscles whose activity which is not controlled by our NERVES. They are also called SMOOTH MUSCLES since they are present as the visceral layer over the organs.

<h2>_____________________________________</h2><h2>DIFFERENCES</h2>

1)      VOLUNTARY MUSCLES are under our control but INVOLUNTARY                 MUSCLES are not under our control

2)      VOLUNTARY MUSCLES are also known as skeletal muscles but INVOLUNTARY MUSCLES are also known as smooth muscles

3)      VOLUNTARY MUSCLES are attached to the bones in the body, but INVOLUNTARY MUSCLES are attached to the soft hollow internal organs.

4)      VOLUNTARY MUSCLES are controlled by the somatic nervous system. INVOLUNTARY MUSCLES are controlled by the autonomic nervous system.

5)      VOLUNTARY MSUCLES  require more energy. INVOLUNTARY MUSCLES require less energy.
