Answer:
45
Explanation:
Both parents are hetero-zygous, so each has alleles Ll.
When Ll crosses with Ll, we have
LL 25%
Ll 50%
ll 25%
So out of 180 offspring, we expect about 25% to have short wings, or
25%*180 = 45

At transform fault boundaries plates moving in opposite directions have a tendency to get stuck resulting in the build-up of large amount of what?
Answer:
The correct answer is - energy.
Explanation:
Transform fault boundaries are the plates that move one past another without causing damage or destruction to the crust, these form when two plates move in the opposite direction or in the same direction.
At transform fault boundaries plates moving in opposite directions have a tendency to get stuck which leads to a high amount of energy formation. There is no damage or destruction that takes place nothing occurs but earthquakes along with the fault.

The products of photosynthesis (glucose and oxygen) are used in cellular respiration. The products of cellular respiration (water, and carbon dioxide ) are used in photosynthesis.
A. True
B. False
Answer:
A. True
Explanation:
The processes of photosynthesis and cellular respiration are extremely correlated because they are part of the same cycle. They are both in the carbon cycle. This works because they each produce what the other needs. It is a constant back and forth reusing the same atoms and cycling all of the molecules. This allows the world to never run out of carbon or other important elements.
Answer:
A. True
Explanation:
Yes, the products of photosynthesis (glucose and oxygen) are used in cellular respiration. The products of cellular respiration (water, and carbon dioxide ) are used in photosynthesis.

Why is it important for geologists to use both relative and absolute ages to determine the age of rocks?
Answer:
to help and determine the exact age of the rocks
Explanation:
The study of rocks strata is known as stratigraphy. It is useful and helps the scientist and the researcher to study the earth's crust and its past.
Scientist could age the rock using two methods. They are :
Relative ages
Absolute ages
Early scientist could determine the exact age of the rock of the earth's crust. They use to find the relative ages of the layers of the rocks and then determine how one rock layer is older or younger than the other. But with advancement and development of carbon dating, scientist could tell the exact age of the rocks found on the earth's crust.
The Scientists uses the relative as well as the absolute dating technique to date the rock layers. They organize the rock layers based on their age and scale from the oldest to the youngest on a geologic time scale. So an exact date of the rocks can be determine by using the two methods of relative age and the absolute age.

A. stimuli
B.impulses
C.responses
D.sense cells
A. Stimuli
WHAT IS STIMULI?
A stimuli is anything that can trigger a physical or behavioral change.The changes in the environment to which living things respond are called stimuli. The living things show response to external stimuli such as heat, light , touch, sound, smell, taste, water and chemicals.It can be internal or external both.When diverse organs works collectively in a scientific way to supply a reaction to the stimulus, this is known as coordination.Stimuli is essentially anything that triggers a receptor for one of those senses.You can understand this with an example that would be the receptors on our skin which sense a stimulus like pain. Sense organs contain groups of receptors that respond to specific stimuli.

Loni makes a diagram to help organize what she has learned about the gas laws.
Which label belongs in the region marked X?
involves changes in temperature
has a constant volume
shows an inversely proportional relationship
does not describe pressure changes
Answer:
Shows an inversely proportional relationship.
Explanation:
The Boyle's law belongs in the region marked X whereas the other circle belongs to Charles law. There is inverse relationship between the two circles or these two laws because in Boyle's law, temperature is constant while on the other hand, in Charles law pressure is constant instead of temperature. In Boyle's law, pressure of a gas is inversely with its volume whereas in Charles law, the volume of a gas is directly proportional to its absolute (Kelvin) temperature.
