Answer: C) density-dependent inhibition of growth.
Explanation:
Cancer cells divide rapidly and grow in number abnormally at a rapid rate. These cells are poorly differentiated and they have abnormal membranes, morphology and cytoskeletal proteins.
In density dependent inhibition the cell growth is inhibited and the density of the cells becomes low. The cancerous tumor cells usually loose the density-dependent inhibition.
Answer:
The correct option is B
Explanation:
The <u>biomolecule used in comparing lizards A and B is the mitochondrial DNA while that used to compare the same lizard B to another lizard C is the ribosomal RNA (rRNA)</u>. <u>They should have compared the same biomolecules throughout</u> by extracting the mitochondrial DNA of the three lizards and then proceed to sequence the whole genome of the lizards. After which they can now do a Global alignment (comparison) of the three sequences together. This procedure would have given them a more accurate information on there identity and similarity.
Answer:
a) Individual 1
b) Overall, the higher the number of mutant alleles, the greater is the concentration of cysteine in urine relative to normal values.
c) The hypothesis may be correct. If number of mutant allele in SLC7A9 is higher than number of mutant allele in SLC3A1, then concentration of cysteine in urine is lower. This means that transportation of cysteine is affected by a greater extent if mutant allele in present in SLC7A9 genetic sequence
d) concentration of cysteine is affected by mutant allele which is a complex protien. If complex protien is low cysteine is not transported back and its concentration in urine is higher
Explanation:
a) Can be inferred easily from table. Higher the mutant allel that is negative, higher is the concentration of cysteine. Hence greater the chances of cystinuria.
b) As explained in part a
c) Observe the pattern on concentration of cycteine and number of - allele. If cysteine is not transported back then its concentration in urine will be higher.
d) The complex protien helps in transportatino of cysteine by binding to it. In the absence of the ocmplex protien, cysteine tends to behave like polar molecule and stay in water that is in excess in urine.
The main reason is because they are heavy, and because they don't have to chase their food. They're not predators and their shells give them protection like running away gives protection to other herbivores.
The answer is d. prevention of muscle strains. Other benefits
of flexibility are Joint health, prevention of low back pain injuries, temporary
reduction of post-exercise muscle soreness, relief of aches and pains, relief
of muscle cramps, maintenance of good posture and balance, relaxation.
