Answer:
The researchers' experimental hypothesis was that changes in actin and myosin overlap would alter the number of myosin cross- bridges that could form within a sarcomere, and specifically that (Primer Section Key Terms O)
A. Increases in overlap favor more cross-bridges to form, increasing muscle force. muscle force. effect on muscle force. fiber) lengths.
Explanation:
Physiologists Alfred Gordon and Fred Julian and Andew Huxley investigated on the strianed muscle´s contraction properties, to demonstrate the way the muscle lenght is affected by changes in overlap between myocin and actin causing the number of cross-bridges increase , increasing muscle´s force as well.
No cross-bridge disruption is caused, nor litlle differences or minimal overlap so B, C and D options are not correct.
Answer:
A DNA sequence codes for the same proteins in different species
Explanation:
All living organisms store their genetic information in DNA (genetic material). The manner through which information in the genes are encoded is the GENETIC CODE. The genetic code comprises of all the codons that specifies amino acids in living organisms. The genetic code has several characteristics, which includes that the GENETIC CODE IS UNIVERSAL
The genetic code is said to be universal because all known living organisms use the same genetic code to encode their genetic information. This means that a DNA sequence codes for the same proteins in several different species. For example, codon AUG encodes the amino acid METHIONINE in every living organism.
Answer:
Land use goes up as human population goes up. This is because the more people there are alive, the more land that people will be using. Hope this helps :)
