Answer:
Scientists need instruments to measure the world. Instruments and sensors are needed to collect data - that takes engineering to design and build them.
Explanation:
The body needs calcium and phosphorous because phosphorus works with calcium to help build bones
Answer:
No
Explanation:
Matter can not be created or destroyed it can only change form. For example two Oxygen atoms can react with one hydrogen atom to form water but the oxygen and hydrogen is not destroyed,
Answer:
- 25 tall individuals, TT
- 50 medium individuals, Tt
- 25 short individuals, tt
Explanation:
<u>Available data</u>:
- The size of this species was determined by a single gene
- TT- Tall
- Tt- Medium
- tt- Short
- Total number of individuals in the progeny, N = 100
There are three phenotypes and only one gene, so it seems that this is an example of incomplete dominance, where the medium-size is the intermediate form between tall-size and short-size.
Cross: between two medium Gazorps
Parentals) Tt x Tt
Gametes) T t T t
Punnett square) T t
T TT Tt
t tT tt
F1) 1/4 = 25% TT, tall
2/4 = 1/2 = 50% Tt, medium
1/4 = 25% tt, short
100% of the progeny ------------ 100 individuals
25% Tall, TT ------------------------X = 25 individuals
50% Medium, Tt -------------------X = 50 individuals
25% Short, tt ------------------------X = 25 individuals
Lady Bug A is a higher percentage because they are CAMOUFLAGED from predators. They SURVIVE and are able to reproduce. This TRAIT is passed on to the offsprings. This process is called NATURAL SELECTION
