Due to collisions between particles in the spinning cloud, the solar nebula begins to flatten. The particles in the gas cloud first have all different speeds in different directions. As they start colliding with each other, their final velocity is the average of the two initial velocities before collision.
Answer:
The flowers can be divided into two identical parts along any imaginary axis through the center. These are further classified as funnel shaped, tubular shaped and campanulate (a bell like shape). Poppy family, cruciform and rose family are few notable examples of actinomorphic morphology.

3/4
Explanation:
If we assume simple dominance and independent assortment for each trait, we can use Mendel's Law of Segregation to predict the phenotypic proportions in the offspring of the parental cross AABBCc x AabbCc.
<h3><u>Gene A</u></h3>
AA x Aa
- F1 genotypes: 1/2 AA, 1/2 Aa
- F1 phenotypes: all A
<h3 /><h3><u>Gene B</u></h3>
BB x bb
- F1 genotypes: 1 Bb
- F1 phenotypes: all B
<h3 /><h3><u>Gene C</u></h3>
Cc x Cc
- F1 genotypes: 1/4 CC, 2/4 Cc, 1/4 cc
- F1 phenotypes: 3/4 C, 1/4 cc
We want to know the proportion of progeny with all dominant phenotype (A_B_C_). Since the genes are independent, we can multiply the probabilities of each gene to obtain the overall probability of having a ABC progeny:
<h3>1 A_ x 1 B_ x 3/4 C_ = 3/4 A_B_C_</h3>
Answer:
There can be alternate explanations for the same evidence
Explanation:
The geology and the biology are two different scientific fields, thus the geologists and biologists have different focus and viewpoints when examining something. When a same experiment is done by scientists from two different fields, it is very likely that the conclusions would be different. The main reason for this is that both of them will have different view and methods to come to the conclusion, as their focus is on different things, or at least the approach is different.
