Answer:
as low as possible and using scanning objective (4x). ... then low power, you won't be able to focus anything under high power.
Answer:
8 amino acids differ between the monkey and the human sequences.
Explanation:
The genome mapping has now made it possible to identify genes that are present on a chromosome. Genetic mapping is also being used to study the similarities between organisms which has helped a lot to understand the evolutionary history among organisms and to assemble the phylogenetic lineages.
Scientists have found the genome of the monkeys to be the most similar to humans with a difference of just 8 amino acids between them. Hence, justifying the hypothesis that humans have evolved from monkeys.
Answer:
Valley lizard = Oviparous
Mountain lizard = Viviparous
Explanation:
In Darwin's theory survival of the fittest, he believed species adapt or change within their environment. So I believe lizards living in a valley would be more safe to lay their eggs but lizards living in the mountains would be viviparous because of the non-predicted and unsafe environment which could harm the better chances of development of the offspring.
Answer:
All are true of the movement of Earth's atmosphere except :
d. Warm air is less dense than cool air so it tends to sink towards the Earth's Surface.
Explanation:
- When gases heat up, their volume increases and density decrease.
- A decrease in density causes a substance to become lighter.
- Thus, when air warms up due to heat from the sun its density decreases and it gets lighter.
- So, it will move up.
- The Cooler air in turn is denser and heavier so it will sink towards the Earth's surface.
- Hence, the statement d , which states that 'warm air is less dense than cool air so in tends to sink towards the Earth's Surface' is FALSE.
