Answer:
The correct answer will be option-
1. Carbon dioxide concentration
2. Light intensity
Explanation:
A limiting factor is a factor which when present in the limited amount limits the metabolic process.
Photosynthesis is a complex process which converts the light energy to the chemical energy converting the carbon dioxide in the presence of sunlight to useful chemical metabolites like glucose.
The photosynthesis process is limited by the concentration of carbon dioxide and light intensity.
The low concentration of carbon dioxide and low light intensity availability decrease the rate of photosynthesis.
Thus, the selected options are correct.
It's infinitely renewable.
While non-renewable energy sources like oil, gas and coal are becoming increasingly scarce, the sun's energy is limitless. Wherever sunlight shines, electricity can be generated.
Answer:
each with an area of 3 square kilometers and each containing 16 at-risk species unique to that preserve
Explanation:
I choose third choice of having each with an area of 3 square kilometers and each containing 16 at-risk species unique to that preserve because allocation of separate preserve provides good space and less competition in that preserve. Less number of at risk species in a large surrounding area increase in population with higher rate due to availability of resources such as habitat, food and water in large amount as well as low competitors for these resources.
Answer:
1/2
Explanation:
This question involves a single gene coding for feather color in chickens. The black allele (B) is incompletely dominant over the white allele (W). This means that the allele B will not mask the phenotypic expression of allele W, hence, a third intermediate blue phenotype (BW) will be produced.
According to the question, if two blue chickens are crossed i.e. BW × BW, the gametes B and W will be produced by each parent. Using these gametes in a punnet square (see attached image), the following offsprings will be produced:
BB, BW and WW in the ratio 1:2:1
BB is black, BW is blue, WW is white. Hence, the probability of producing a blue chicken from this cross is 1/2.
