Answer:
the number of individual organisms born into a population in a given year - Birth rate
the movement of individuals out of a population - Emigration
the number of individual organisms that die in a population in a given year - Death rate
the movement of individuals into a population - Immigration
Explanation:
The birth rate describes the frequency of live births in a population. In contrast, the death rate, also called the mortality rate is the number of deaths in a population. They are usually reported as a number per 1000 people, per year.
Migration is the movement of organisms. Immigration is used to describe the act of organisms in a population into a new destination. Emigration is the act of organisms leaving their current population

See explanation
Explanation:
We know that the momentum of a body is defined as the product of mass and velocity of the body.
Let us now obtain the momentum for each item on the list;
Football player = 100 * 10 = 1000 Kgms-1
Skier = 60 * 20 = 1200 Kgms-1
Frog = 0.9 * 12 =10.8 Kgms-1
Meteorite = 0.1 * 1000 = 100Kgms-1
Base ball = 0.14 * 30 = 4.2 Kgms-1
Satellite = 3000 * 8000 = 24000000 Kgms-1
Steel ball = 2.0 * 2.8 = 5.6 Kgms-1
Answer:
here.
Explanation:
17. antibiotics
18. reproduction (growth is increase in size and number)
19. cell walls (like penicillin. This mechanism is important because it will not harm the host as human cells don't have cell walls.)
20. 70S ribosomes (because this is where protein synthesis occurs in bacteria)
Honestly i know its the adult stage
