Answer:
C
Explanation:
When researching on the lineage of 2 animals from a common ancestor, one can deduce it accurately from DNA samples and various bodily characteristics from the body of the 2 animals in comparison to the common ancestor.
A) Strands of DNA allows for scientist to deduce the percentage similarity between 2 animals. The more similar means that the closer the relatedness is between 2 species.
B) Bones and muscle structure gives one a rough gauge on similarity of both organisms. E.g. Compare human bone, muscle to chimpanzee bone muscle.
C) Comparison of food items is the worst methods as different species may feed on different types of food due to natural selection. E.g. Finch bird example on the galapegos island or sth.
D) growth of embryos of similar animals would have similar developmental stages and changes that is quite distinct to each species, allowing one to deduce the closeness of the 2 animals to a common ancestor.
Crab in Rocky shore By rock pools - deep in ocean as they get older
Typical day - just shuffle along the rocks
To get food - from rock pools use claws to get fish
As they get bigger, they eat protozoa, diatoms and smaller crabs that live on the ocean floor. When the crabs reach 2 to 4 years of age, they move to deeper water where they join the adult crabs that eat worms, clams, mussels, snails and sea urchins. They also eat sand dollars, barnacles, fish parts and algae.
Hard shell is their protection and claws as a defends mechanism
PredAtors - possibly birds while on shore but bigger fish on ocean floor
Answer:
1. Wind moves horizontally because of differences in air pressure. These differences in air pressure are a result of __differential______ heating of earth’s atmosphere from the _sun____.
2:This pressure moves from an area of __high___pressure to an area of__low___ pressure, creating the wind.
Explanation:
The sun rays ‘hit’ the earth's surface with increased obliquity with increasing latitude. In addition, the density of the sun rays per sq meter also decreases with increasing latitude. This is all due to the spherical nature of the earth.
However, there are also local differences that cause the earth's surface to heat differentially such as terrain and cloud cover, etc. This creates regions of warmer air mass (low-pressure zones) and cooler air mass(high-pressure zones). These differences cause winds because of air rushes from high to low-pressure zones due to differences in air masses’ temperature-related densities.
