Antibody binding to the receptor may cause the two parts of the receptor to dimerizeantibody binding to the receptor may cause the two parts of the receptor to blank, which normally occurs when a blank binds. this would result in the activation of the cell response even in the absense of the signalling molecule.
a) true
b) false

The correct answer would be -

Blank 1) dimerize,

Blank 2) signaling molecule, and option a) true.

Explanation:

Dimerization takes place after the signaling molecules attach to the receptor. Dimerize of antibody takes place when the antibody bind to the two parts of the receptors.

Even in the absence of a signaling molecule, signal transduction occurs. It could be possible due to mimicking the interaction and activate the receptor.

Thus, the correct answer is-

Blank 1) dimerize,

Blank 2) signaling molecule, and option a) true.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.

in the year 2850, humans successfully colonized mars. the martian modules that were constructed could hold only a small population of people. it is now a century later, and the population on mars has grown to 600 people. of the current mars population, 45 people express the recessive phenotype for phenylketon- uria (pku) syndrome (pp genotype).
