Why are few large invertebrates found living on land

1 answer:

8 0

Almost all invertebrates happen to be insects, worms, or other small critters that we usually consider as pests. There aren't many relatively "large" invertebrates that live on land.
Nonetheless, here are some examples.
1. Ants
2. Beetles
3. Grasshoppers
4. Slugs / Snails

Where in the cell was the ATP produced?

WITCHER [35]

This energy gets trapped in the ATP as it converts from ADP to ATP by the addition of phosphate. There are 3 main pathways for harvesting energy from glucose: Glycolysis - begins glucose metabolism in all cells to produce 2 molecules of pyruvate. Occurs outside of mitochondria, usually in cytoplasm

1. What environmental issue are you most concern about? Why?

True [87]

Answer:

1. Global warming (as we pass a threshold, it may be irreversible)

2. Reduce the emission of greenhouse gases

Explanation:

Climate change is a general phenomenon associated with the effects of global warming caused by anthropological activities, especially the emission of greenhouse gases (e.g., carbon dioxide, methane, nitrous oxide, etc). It has been shown that global warming is causing an increase in the temperature on the planet at a speed unprecedented since the beginning of the Industrial Revolution. The increase in greenhouse gases in the atmosphere is a direct consequence of human activities, especially from the use of fossil fuels in electricity, heating, transportation, etc. In consequence, it is possible to reduce the impact of global warming by using renewables climate-friendly energy resources, for example, by using solar panels for electricity, solar water for heating and eolic energy for industry (electricity). In this context, it should be taken into account that global warming may be irreversible, and we have the tools to stop it before it is too late.

The cladogram shown below describes the evolutionary relationship among several species, labeled A to F. The five dots represent

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 tree-type graph based on cladistic analysis. 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 -sequencing- represents their phylogeny.

The sequencing 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.
