Which describes gas exchange in the respiratory system?
Answer:
The alveolar membrane- is where gas exchange between the blood and the atmosphere takes place. The gas molecules must diffuse across the alveolar epithelium and the capillary endothelium. ... Thus, the alveolar surface (as well as the respiratory bronchioles) have no cilia or mucus layer.
Explanation:

Answer:
A - Gas exchange happens through diffusion.
Name the tissue which allows buoyancy to aquatic plants? * a) chlorenchyma b) collenchyma c) aerenchyma

Can light cause changes to metal
Answer:
yes it can cause changes to metal
Answer:
No.
Explanation:
The metal can't change because light is not a physical thing. the metal can change by getting warm and/or changing color, because different types of light can cause different changes to a material when they are absorbed.

Identify the strengths and weaknesses of Mendel’s Law of Independent Assortment.
Answer:
Explanation:
Mendel propel two laws The law of inheritance and that of independent assortment of gene.
Independent assortment of gene explain that alleles of a gene assort independently and that different Allele can show different phenotypic effect and differences. This means that in a gene where we have 2 allele they can both show individual difference where one can have a dominant effect over the other and the other allele is recessive.
This law does not take care of linked gene where alleles don't separate after crossing over sister chromatids but are rather inherited together given rise to complex inheritance.
Pleiotrophy effect of a gene where a gene is having many effects.

What are some ways that the nitrogen cycle overlaps with or influences the oxygen and carbon cycles?
Are any of these interactions between the cycles positive?
Are any negative?
What about when the nitrogen cycle is thrown off balance by the Haber-Bosch process and others like it?
How can that influence the oxygen and carbon cycles?
Are there other cycles involved that have not been mentioned in this question?
What does this discussion suggest about the nature of the Earth as one large system?
Answer:
1. Nitrification occurs when soil microbes convert ammonium into nitrate. Much of the overlap between the carbon cycle and the nitrogen cycle occurs in the soil, in processes conducted by soil microbes. Microbes break down nutrients, build new compounds for their own growth, and eventually die.
The second question im not sure sorry- the positive and negative one ;(
3. Many human activities have a significant impact on the nitrogen cycle. Burning fossil fuels, application of nitrogen-based fertilizers, and other activities can dramatically increase the amount of biologically available nitrogen in an ecosystem. As nitrogen makes up 78% of the atmosphere, there is no shortage of it – it just isn't in a form plants and animals can use.
4. Carbon makes its way through living things as carbon-based compounds, like energy molecules, fats and proteins, eventually cycling its way back into the atmosphere. Nitrogen is mainly found in the atmosphere as well and enters the ecosystems as nutrients for plants. Water, nitrogen and carbon cycles. Carbon moves from the atmosphere and back via animals and plants. Nitrogen moves from the atmosphere and back via organisms. Water moves on, above, or below the surface of the Earth.
5. Carbon cycle, Nitrogen cycle, Nutrient cycle, Oxygen cycle, Phosphorus cycle, Sulfur cycle, Rock cycle, Water cycle.
6. Wind, water, and ice erode and shape the land. Volcanic activity and earthquakes alter the landscape in a dramatic and often violent manner. And on a much longer timescale, the movement of earth's plates slowly reconfigures oceans and continents. Each one of these processes plays a role in the Arctic and Antarctica.
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. Earth's surface is the only habitat available to the human race. Understanding the processes by which that habitat has been created and continually altered is important to determine the causes of environmental degradation.
Where are metamorphic rocks likely to form?
Answer: deep in planets crust
Explanation:
Although metamorphic rocks typically form deep in the planet’s crust, they are often exposed on the surface of the Earth. This happens due to geologic uplift and the erosion of the rock and soil above them. At the surface, metamorphic rocks will be exposed to weathering processes and may break down into sediment.

How are the process by which animal and plants obtain energy different
Answer:
Plants absorb sunlight and turn it into energy. Animals eat other animals or plants for energy.
Hope this helps
Explanation:
Answer:
The process by which animals and plants obtain energy are different because animals get energy from eating food and plants get energy from sunlight.
Explanation:
Plant get it because they collect energy from the sun and use carbon dioxide and water in the process called photosynthesis to produce sugars.
AND
Animals get it because Animals can make use of the sugars provided by the plants and they can also eat meat or plants to get energy from them so that means when you eat food animals get energy.
ANSWER:- Plants get energy from sun.
Animals get energy from food.

Carbohydrates,Lipids (fats),Proteins,Vitamins,Minerals,Water.How can selective breeding "force" evolution
to occur?
Answer:
Domestication accounts for a significant influence on the evolution of a species. ... Through selective breeding, we may have influenced aid to the survival of a species. Adversely, we may be leading some species to negative results. Indeed, great changes have been implemented because of selective breeding.
Polar bears feed on seals. So, polar bears and seals share a . Climate change has caused ice caps to melt in colder regions where polar bears live. This change has caused them to hunt less. This situation will lead to .
Polar bears and seals are animals that share a prey-predator relationship, whereas climate change causes less biomass at the quaternary level.
What is the prey-predator relationship?The prey-predator relationship is s type of ecological association where one species is hunted (the prey) by another species.
Moreover, climate change is well known to produce global warming and melting ice on the Earth's poles.
In conclusion, polar bears and seals are animals that share a prey-predator relationship, whereas climate change causes less biomass at the quaternary level.
