The environment includes abiotic (nonliving) and biotic (living) factors. An ecosystem consists of all the biotic and abiotic factors in an area and their interactions
Answer:
have curved protofilaments at their plus ends
Explanation:
Microtubules are polymers of tubulin proteins that function as the cytoskeleton of eukaryotic cells. Microtubules are dynamic structures that can grow and shrink at a rapid rate. During this process, tubulin subunits can associate and dissociate at the plus end of the protofilament. Tubulin subunits bind to two GTP molecules, one of which is hydrolyzed to GDP after assembly. When microtubules are unstable, protofilaments curl outwards because GDP-bound tubulin has a weak affinity (thereby curving it) and disassemble. The dynamic stability of microtubules is regulated by a feedback loop: when microtubules shrink, free tubulin concentration increases and microtubules start to grow. As microtubules grow, free tubulin concentration decreases and the rate of GTP-tubulin addition also decreases.
Answer:
The probability of obtaining a "goober" butterfly is 6.25%
Explanation
If there are three possible combinations of butterflies, with yellow and blue being dominant, green is supposed to contain a recessive pattern, so according to Mendel's law of character independence, the pattern RR and BB manifest the dominant phenotype yellow, blue or yellow and blue in spots, the green pattern must be recessive is represented by the letter a, the punnett graph is made, obtaining that 56% present a dominant pattern, 37.5% will be spotted and the pattern recessive must match to generate 6.25% of butterflies “goober”.
Explanation:
Combine like terms.
-2y + 7y = 5y
-4 - 5 = -9
So the answer would be <u>5y - 9</u>
Answer:
Sam is correct. It is a chemical change and the contents should be in D. for compound.
Explanation:
This answer is correct because I just took the USA test prep
Good Luck!
