1) B
(I'm not so sure of this one) All of the other options have a steady impact on population regardless of the density of organisms except competition
2) D
Increased carbon dioxide levels would not hinder plant growth, and tsunamis aren't really linked to carbon dioxide levels. Increased carbon dioxide is unlikely to lower the air temperature so only D is left.
3) A
4) Three properties of water that allow it to sustain life are that it is adhesive, it is a good solvent, and cohesion. Adhesion is important in situations such as water travelling up xylem tubes in plants so that the water is not pulled down by gravity and can reach parts of the plant that need water. Cohesion allows the water being pulled up the xylem to stay together and for water molecules to be pulled when a neighbouring one is moved. Water being a good solvent allows inorganic minerals to be taken with water through vascular tissue, such as in the previous example.
There are many benefits provided by biodiversity. It can be in our biological resources, ecosystem services and also social benefits. The three social benefits provided by biodiversity would be the following:
1. Research, education and monitoring
2. Recreation & tourism
3. Cultural values
Explanation:
Biodiversity is “the variability among existing animals from all causes including temporal, marine and other aquatic ecosystems, and the environmental complex.
Pollinators, including bees and butterflies, contribute meaningful environmental and economic advantages to agricultural and essential ecosystems, including adding heterogeneity and productivity to food crops. As many as one-third of the world's food production relies directly or indirectly on insect pollination.
No Spanish sorry about that
Answer:
the correct answer is: chloroplasts
Explanation:
Chloroplasts are the cellular organelles that in photosynthetic eukaryotic organisms take care of photosynthesis.
The characteristic shared by both algae and seed plants is the presence of chloroplasts. Algae and seed plants both have chloroplasts.
