7. Imagine that all nations agreed to reduce greenhouse gas emissions by half in an effort to reduce global warming. In what ways could you revise this simulation, so it accounted for the influence of this solution on arctic habitat, and on the whale and seal populations?
If all nations agreed to reduce global warming then It would be good because the seals need icy conditions. So the less global warming then the more icy habitats there will be and the seals will have more places to live.
Hope this helps
The positive effect is that these greenhouse gases affect the arctic ecosystem, which also has a detrimental impact on the creatures that dwell there.
What is the effect of greenhouse gas?Because these greenhouse gases affect the arctic ecosystem, which also has a detrimental impact on the creatures that dwell there, having a positive effect.

Explanation:
The scientific method is an empirical methodology used by scientific disciplines to acquire knowledge. This method provides a standardized and objective approach to make investigations (and thus obtain knowledge). The scientific method consists of 1-to make a question in order to explore a phenomenon of the natural world; 2- to raise a hypothesis, i.e., a plausible explanation of the question and deriving predictions if the hypothesis is true, 3-to make experiments and/or observations and, finally, 4-to arrive conclusions, which are the answers derived from the experimental procedures.
What is a disadvantage of asexual reproduction?
Answer:
Asexually reproduced offspring would have no genetic variation from the parent, being a perfect copy. This makes it so there is no genetic variation and disease would easily spread, since there would be no chance of an immunity gene showing up.

What are the Layers of the Earth?
The Earth is made up of three different layers:
1.The Crust
2.The Mantle
3. The Core
1. The Crust
It is the outer layer of the earth which is mainly composed of solid rock of basalt and granite. There are two types of crust which are oceanic and continental.
2. The Mantle
The mantle lies beneath the crust and is up to 2900 km thick and consists of hot, dense, solid rock containing iron and magnesium. The crust and the upper part of the mantle divide the lithosphere into both major and minor plates.
3. The Core
The core is the center of the Earth made up of two parts: the liquid outer core and the solid inner core. The outer core is made of nickel, iron and molten rock.
Thus, the inner core is hotter than the surface of the sun. So, the correct option is (C).

Today, the common type of banana we eat is a Cavendish banana. They arose from chance mutants that were produced sexually from wild banana plants. The Cavendish banana is infertile and can only be produced by cloning root shoots. Large commercial growers worldwide now plant only the mutant type. Some information about both types of banana is recorded in the table.
Growers on large banana plantations that supply food commercially have chosen to limit their plantings exclusively to Cavendish banana plants. Why are scientists warning that exclusively growing this mutant type by asexual reproduction presents a serious disadvantage
1.The loss of an adequate Cavendish banana seed supply could result in extinction of both varieties of plants.
2. The changes in characteristics from a parent plant to a clone will produce inconsistent plants that are less healthy.
3.The lack of genetic variability among clones puts the whole species at increased risk of extinction through a catastrophic disease or pest.
4.The increasing number of homologous sets of chromosomes crossing over with each successive generation of clones will eventually result in widespread death of banana plants.
Answer:
The lack of genetic variability among clones puts the whole species at increased risk of extinction through a catastrophic disease or pest.
Explanation:
Every living organism, be it a plant or an animal, has its own way of reproduction and its own mechanisms of how to cope with dangers. In recent times though, we see that there are more and more organisms, mostly plants, that are not fertile, thus they can not reproduce on their own but need human assistance. This is the case with one of the most popular fruits in the world, the banana.
Virtually, all bananas that are produced commercially are not fertile, but they can only be reproduced by cloning them. While this may not seem like something that terrible, it actually is. Every single plant that is used for commercial production is exactly the same, thus the genetic variation is lacking totally. By having zero genetic variation, if only one plant gets diseased by a disease that spreads out easily and is fatal, it will affect every single banana plant, and by having no genetic variation, the effect will be the exact same at all of them. This kind of scenario can very easily lead to the rapid extinction of these bananas and the loss of one of the most consumed fruits in the world.

7. Pick two of Earth's spheres (biosphere, atmosphere, geosphere, hydrosphere), and draw a model showing how these two systems interact. Your model should show components of these systems, at least one way these components interact, and inputs and outputs that move from one system to another.
Answer:
alright, the answer is biosphere
Explanation:
The earth sphere that is the biosphere is a product of the interaction of atmosphere, lithosphere, and hydrosphere. Together they are called as the geosphere.
All these spheres interact with one another and their interaction leads to life on earth. The atmosphere consists of the most essential gases known to maintain temperature and sustain life on earth such as oxygen. The other component knows as the hydrosphere has water which when interacts with air through the processes of evaporation, condensation, and precipitation all driven by the solar mechanisms.Thus the air and water cycle interaction leads to the input and output of energy in the ecosystem.

O Biology is the science of exception, Justify it with
examples
Answer:
Biology deals with living organisms which show enormous variations and, therefore, numerous exceptions are found.
There are two reasons:
Each organism evolved in a different way to adapt to their environments the best way possible.
It is not really so. There are common rules to biology as in physics, but the problem is we study much more complex systems. More complexity results in more emergent properties, thus they appear to be exceptions.
Biology deals with living organisms which show enormous variations and, therefore, numerous exceptions are found.
justifying it with examples:
1. All living cells have a nucleus except mature red blood cells of mammals.
2. Red blood cells of all mammals are without nucleus except those of camel.
3. Stem is the part of plant above the ground but potato, corm and ginger are underground stems.
4. Blood of all vertebrates is red due to the presence of hemoglobin but a shark, Carcharhinus, has colorless blood.
by the above examples you can see that biology the science of exception.

Which of the following shows a correct base pairing in DNA?
A and G
T and G
C and A
Gand C
Answer: G and C
Explanation: DNA carries the hereditary information for organisms. W ithout DNA, our species would be unable to pass traits from generation to generation. DNA controls all aspects of an organism. It tells spiders how to spin webs, birds to lay eggs, and what color to make your eyes. The genetic information in DNA is stored as special chemical sequences, called chemical bases. The chemicals bases are adenine (A), guanine (G), cytosine (C), and thymine (T). Each base connects with another to form base pairs. Adenine always pairs up with thymine. Cytosine always pairs up with guanine

Stand and let your hands hang next to your sides for a few minutes. Then, look at the backs of your hands. Do you see any bumps on the surface on top of your veins? What might those be, and what are their function?
When you stand and let your hands hang next to your sides for a few minutes, the bumps you see on your veins are the valves that help move blood to the larger veins.
What we know about vein valves.There are valves located throughout the veins in our bodies. Most of these are located in points where smaller venules fuse with the larger veins.
Their function is to prevent blood from flowing back into the smaller veins, thus helping with the normal blood flow of the body.
Given that the veins in our bodies are littered with small valves to help the blood return to the heart correctly, we can confirm that these are the small bumps that we can see when letting our hands down for a few mins, as they fill with the blood they try not to let flow back into the smaller veins.
