Answer:
Explanation:
Science process skills are the things that scientists do when they study and investigate. Observing, classifying, communicating, measuring, inferring and predicting are among the thinking skills used by scientists, teachers and students when doing science.
Answer:
The first male was bb Ee, and the second male was bb EE.
Explanation:
In Labradors coat colour is controlled by two genes. Suppose the two genes are B and E. B produces black colour and recessive form bb gives brown colour. Gene E is epistatic over gene B in its recessive form which means that ee will produce yellow colour regardless of the genotype present of B gene.
The first case is possible if the female lab is bbee (yellow) and the male lab is bbEe (brown):
bbee X bbEe
bE be
be bbEe bbee
So half of the offspring will be brown (bbEe) and half of them will be yellow (bbee)
The second case is possible if the same female bbee mates with a brown male of different genotype which can be bbEE:
bbee X bbEE
bE
be bbEe
So all offspring will be brown (bbEe)
Hence, the first male was bbEe and the second male was bbEE.
200J
Explanation:
Given parameters:
Force on boulder = 100N
Distance moved = 2m
Unknown:
Work done = ?
Solution:
Work done on a body is the force applied to move such body in the direction of the force.
Work done = force x distance
Input the parameters in the equation:
Work done = 100 x 2 = 200Nm or 200J
The work done in lifting the boulder is 200J

Answer:
b. adding butter. increasing the ripeness of fruit.
Explanation:
The addition of whole kernels helps to reduce the glycemic index (GI), because the larger the carbohydrate particle, the longer it takes the body to absorb it, decreasing the blood glucose peaks.
In addition, the addition of <u>lean</u> <u>protein</u> to meals helps to lower glucose spikes by reducing digestion time.
The addition of a fat like butter would not reduce the glycemic index due to its energy load (9 kcal per gram). In addition, increasing the ripeness of the fruit will also increase the GI.
