Answer:
apical growth is the growth that occour on plants that is responsible for height. it is present in the top of the plant . if it were cut then the plant cant grow
1. ___1___ : ____1____ is the ratio of homozygous to heterozygous offspring.
The answer is 1:1. It could also be expressed in percentage which is 50% : 50%. This is derived by dividing the number of a particular genotype against the whole offspring population. In this case, each genotype is 2/4 * 100 in percentage.
2. ___50____ % are the homozygous recessive.
The answer is 50%. Homozygous recessive means that, in the genotype of the offspring, both alleles of the gene are recessive. In this case, it is rr. As indicated above, this is derived by 2/4 * 100 since there 2 out of 4 of the offspring are recessive homozygous.
Yes you can write a report about rocks and minerals. Use compare and contrast in the report. Perhaps describe how minerals and rocks came from.
Answer:
The biological concept of species states that if 2 organisms can interbreed and produce fertile offspring they belong to the same species.
Scientist could observe them under natural conditions and check if they can reproduce to produce fertile offspring.
Answer:
There is no change, the lac l gene is constitutively expressed, regardless of the presence of lactose.
Explanation:
Lacl gene codes for the lac repressor hence is always expressed to produce lac repressors which may or may not be bounded dependent on the presence of lactose. Lacl gene expression is not regulated, thus is constitutively expressed.
