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.

What kind of genetic factors affect algae growth?
ANSWER :
Algae prefer stable conditions. Low water levels create slower, more uniform conditions that encourage algae growth. Warmer water leads to increased algae growth. The temperature of the water may even favor the growth of certain types of algae over others. Nutrients, like nitrogen and phosphorus, fuel algae growth; however, excess nutrients from human activities can exacerbate algae blooms.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.
Why are plants unable to grow at the bottom of lakes ?
Answer:
I think its because of the water pressure
Explanation:
Answer:
I'm guessing that it's because there isn't enough sunlight at the bottom of a lake. The water reflects light, and plants need enough sunlight since they use photosynthesis to get their energy.

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.
