Answer:
20 ( B )
Explanation:
Given data:
a and b are 10 map units apart
b and c are 20 map units apart
a and c = 30 map units apart
<em>condition </em>; Triple heterozygote testcrossed
number of progeny = 1000
<u>Determine the number of double crossover result </u>
P( crossover between a and b ) = 10/100 = 0.1
P( crossover between b and c ) = 20/100 = 0.2
p( double crossover ) = 0.1 * 0.2 = 0.02
hence number of double crossovers = number of progeny * 0.02
= 1000 * 0.02 = 20
Answer:
C. capillaries connect arteries and veins.
Explanation:
A is false, veins carry blood towards the heart.
B is false because arteries are the thickest blood vessel.
C is completely true
D is false, heartbeat is controlled by electric impulses
1) Aerobic Respiration 2) Photosynthesis
Aero means Air, or in this case Oxygen, so Aerobic Respiration needs air, Photosynthesis uses Carbon Dioxide, Water, and sunlight to create Oxygen and sugars
Answer:
the sunlight one will thrive
Explanation:
a lamp is artificial light.
Answer:
1. adaption
Explanation:
Salmon have special adaptation behavior that allows them to live in both freshwater and saline water during their lives.
<u>Salmons are born in freshwater where they spend few months and then move to saline water. For laying eggs, they again move to freshwater because eggs are unable to survive in saline water due to a process known as osmoregulation.</u>
Moving from freshwater to ocean water, salmon adapt according to the environment for their survival.
Hence, the correct answer is "1. adaption"
