Which has a bigger effect on who we are:our genes or the way we are raised
Answer:
The correct answer is option a. "the cells will shrink due to water loss by the cell".
Explanation:
Cells placed in a hypertonic solution will shrink due to water loss by the cell. An hypertonic solution has a high content of solutes dissolved, which makes it a solution with high tonicity. Water tends to move from a solution of low tonicity to a solution with high tonicity. As a result, cells placed in a hypertonic solution will start to loss their inner water and shrink, which causes its death.
Keystone species are species
whose roles have a large effect on the types and abundance of other species in
an ecosystem. Keystone species are important in the ecosystem as they help to
determine the whole ecosystem and without them, the ecosystem would be different
or stop to be in existence. Almost all animals that have a significant impact
on the food webs are examples of keystone species.
Answer:
Genetic modifications to livestock would most likely suit to increase their longevity and marketability.
Explanation:
One of the bigger problems facing livestock is disease. Genes for bacterial resistance would likely increase the yield of livestock over time. Additionally, livestock raised in hot/cold climates could benefit from genes that adapt them better to these conditions. For example, cattle raised in hot conditions would benefit from genes that increase sweating or decrease passive water loss like through defecation.
Additionally, tailoring livestock to consumer desires would increase marketability, and therefore profit. For example, an ideal steak has a set fat content. Genetically modifying cows to maintain this fat content would increase the value of its meat.
