From the deepest to most superficial: pia mater, arahnoid, dura mater
Answer:
The tall parent was heterozygous
Explanation:
If tall height is dominant to short height the only genotype possible for short height is hh, while there are two possible genotypes for tall height, Hh and HH. When HH is crossed with hh all the offspring are Hh, but if Hh is crossed with hh, a quarter of the offspring is HH, a quarter is hh and half is Hh. If the tall pea plants were HH there would only be tall offspring, but because there are some short offspring we know that the tall pea plants must have a genotype of Hh.
Answer:
A. Lipid A
Explanation:
The outer membrane of Gram-negative bacteria is present outside to the thin peptidoglycan layer. The outer membrane consists of lipopolysaccharide (LPS) which is the molecule having both carbohydrates and lipids.
The lipopolysaccharide has three parts out of which lipid A is the toxin one. Lipid A is embedded in the outer membrane through its fatty acids. When lipid A enters the blood stream of the host cell, it leads to septic shock. Lipid A is heat stable and highly toxic.
The correct answer is A. 20.2 s
Explanation:
The table shows there were three trials to measure how much time a toy car needs to move 1 meter on different surfaces. Now, to find the average time on a surface simply add the results of the three trials and divide this by number 3 (number of trials). The process to know the average time on dirt is shown below:
20 + 19.2 + 21.5 = 60.7 - Results of each of the trials
60.7 ÷ 3 = 20.2 s - Divide the total by the number of trials
This means the average time for the toy to move on dirt was 20.2s
Answer:
D. Fungi
Explanation:
Fungi does not contain the green pigment chlorophyll and therefore are incapable of photosynthesis.
