Answer:

Since the origin of humans on this planet, they have been trying their best to make their lives easier on this planet. In doing so, human activities have some how heavily damaged the Earth. Many day to day activities of humans are dangerous for the Earth.

Some of the consequences of human activities on the Earth's fresh water are :

Extinction of many aquatic species:

The water consumed by humans comes from the fresh water oceans. As the population of humans is increasing enormously, the water from the oceans is being consumed at dangerous levels. This has caused many species of aquatic animals to become extinct or to be at a verge of extinction as they do  not have a habitat to survive or reproduce.

Pollution:

Many heavy industries, house sewage, farmers dispose waste into the fresh water. Hence, killing aquatic animals and polluting the fresh water ecosystems.

Answer:

In the lab, I observed how pollutants affect the pH of lakes and groundwater. Pollutants that result from human activity such as using soap and citric acid can change the pH of water. If the pH of the water changes, it might not be safe for people to drink that water or for organisms to live in it. I also learned that the pollution in a lake can end up in groundwater. Even though the soil can filter some pollutants and the water may look clean, its quality may not be good.

What are some viable ways of lessening the effect that increased carbon has on the following?
Art [367]
<span>The ways for lessening the effect of increased carbon include reducing the components of the carbon footprint (the amount of carbon dioxide and other carbon compounds emitted due to the consumption of fossil fuels).</span> Air travel is one of the main components of the carbon footprint. <span>The solution for reducing the amount of carbon dioxide in the air is to burn fewer fossil fuels, but it is very difficult because the burning of fossil fuels is necessary for heating, electricity generation and transport.</span>

Power stations that burn fossil fuels to produce electricity are one of the main contributors of carbon dioxide in the atmosphere and the way to reduce it is to use less electricity which can be done by turning down the heating at home, insulating home, <span>using low-energy lamps etc.</span>

When you get your haircut, which type of protein is being cut off? Is it Globular or Fibrous? A. Keratin, Fibrous B. Transport,
marusya05 [52]

Hairs are mostly fibrous proteins and are composed of keratin, and also the main constituent of skin, nails, wool, woof, feathers etc.

Keratin is the essential fibrous protein which has a structural and protective functions in the epithelium.

.Proteins can be visualized in many ways, each of which highlights a specific aspect of the protein. Drag the terms on the left
ANTONII [103]

Answer:

1. Space-filling

2. Ribbon model

3. Wire frame

4. Simple shape

5. Simplified diagram

Explanation:

"attached is the question"

A protein can be visualized using different types of models. The models you use will depend on what you want the viewer to understand. A space-filling model would show all the atoms that composes a protein. This type of model makes use of spheres, emphasizing the globular structure of the atoms. They are proportional to the actual size of the atom they represent.  Each type of atom is a different color. Even the distances of the spheres are proportional to its size to help viewers better see the actual shape of the protein. Ribbon model is also a 3D representation of a protein. It shows the only the backbone of the protein. It highlights the folds and coils in a protein, generally the organization. Some versions show the α-helices as ribbons and β-strands are shown as arrows. Wire frame model is like the ribbon model but it also shows the side chains. It shows the different atoms that are involved. Thin wires show the bonds made between the atoms and the wires bend show the relative location of the atoms. A simple shape focuses more on the function of the protein overall rather than the internal structures. The shape does not represent a particular protein, merely using a general shape to represent a protein. A simplified diagram shows more detail than the simple shape. It shows the internal structures as well but like the simple shape model, it focuses more on the function of the protein. A version of it is a solid shape, which does not show the internal structure.

If two organisms show a developmental homology you would also definently expect them to?
san4es73 [151]

If two organisms show a developmental homology you would also definitely expect them to share genetic homologies.

Homology is the similarity between two organisms. This similarity can be of body structures, physiology, etc. This homology is generally due to shared ancestral history between two organisms. For example, the wings of a bird and bats are homologous structures, this is because they have a common anatomy.

Genetic homology refers to the arrival from the same gene from a common ancestor. The same gene is shared between two organisms who may not be related in any other matter. Genetic homology can even be depicted by the sequences of a protein.
