Answer:
Decrease
Explanation:
Acceleration is inversely proportional to the mass of an object.
Acceleration decrease as the mass of the object increase
If u use the formula F=ma to calculate, you will get
a=0.5m/s2 for the first situation (m=10kg) and a=0.25m/s2 for the second situation (m=20kg)
Answer:
the vaccine causes the immune system to produce antibodies to the virus that causes the measles
Answer:
- Interruption in the genetic flow between separated groups
- The emergence of new mutations in each of the groups, and their accumulation in time. Slow and gradual differentiation between populations.
- Genetic divergence by natural selection and reproductive isolation
- Prezigotic isolation mechanisms
Explanation:
Allopatric speciation consists of the geographic separation of a continuous genetic background that can give place to two or more new geographically isolated populations. These separations might be due to migration, extinction of geographically intermediate populations, or geological events. In this speciation, some barriers impede genetic interchange, or genetic flux, as the two new groups that are separated can not get together and mate anymore. These barriers might be geographical or ecological.
The process of allopatric speciation involves different steps that affect organisms:
- The emergence of the barrier.
- Interruption in the genetic interchange
- The occurrence of new mutations and their accumulation in time in each population. Slow and gradual differentiation.
- Genetic divergence by natural selection and reproductive isolation makes it impossible for the two groups to mate even if the barrier disappears.
- Prezigotic isolation mechanisms will be favored by selection if occurs a secondary contact between the new species in formation.
Earth’s axis passes through the North and South Poles. It takes Earth 24 hours to rotate once around its axis. Earth revolves once around the Sun in 365 days during a non-leap year.
Answer:
Explanation: Deforestation leads to climate change. The fewer trees in environment, the more carbon emmsision there is which warms up the earth. As the earth gets warmer the glaciers and ice caps in the artic and antarctic melt which leads to more water in the ocean. Think of ice melting in a glass of water, the ice melts and turns to water creating more water.
