Answer:
The correct option is;
7:32 AM
Explanation:
The information given are;
The time at 45 degrees W and 72 degrees N = 9:32 AM
The variation of time with lines of longitude is given as 15 degrees for each 1 hour variation, therefore, where we have the other location at 75 degrees W and 45 degrees S, the difference in the longitude = 75 - 45 = 30 degrees west of the initial location
Moving west is in the opposite direction of the Earths rotation, therefore, we subtract 1 hour for every 15 degrees giving 30/15 = 2 hours subtracted
The time at 75 degrees W and 45 degrees S is therefore, 9:32 AM - 2 hour = 7.32 AM
The latitude of a place left out in the calculation of the relative time of a place.
Answer:
I would say that its they are descendant of a common ancestor. DNA shows that our species and chimpanzees diverged from a common ancestor species that lived between 8 and 6 million years ago.
Explanation:
Answer: Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose.
Explanation:
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
