This question doesn't make since. it could mean its death rate is lower than its birth rate or it could mean just expansion
Answer:
The correct answer is - 50%
Explanation:
In the heterozygous condition, there is always one allele of dominant and one allele of recessive present together and during gamete formation, they assort independently. The probability of the pink flower that is RW can be found by punnet square:
R W
R RR RW
W RW WW
here, out of four two cases is of heterozygous or pink flower so the ration would be 2/4 or 1/2 or 50%
Answer:
(b)- zone of hypertrophy
Explanation:
Hypertrophic cells synthesize alkaline phosphatase by calcifying the surrounding area; prevent the diffusion of substances, this causes chondrocyte death; therefore, the matrix degrades and the lagoons converge, then the blood vessels proliferate in the collarete to vascularize the cavity. The primitive periodic cells migrate to the vascular borders to become osteoprogenitor cells which are attached to the cartilaginous spicules leaving the degradation of the calcified cartilage, then they become osteoblasts. The combination of cartilage and bone matrix forms a mixed spicule.
Endochondral bone growth begins in the second trimester of fetal life and goes to adulthood, in it there is presence of epiphyseal cartilage.
The epiphyseal cartilage has several areas including:
<u>Hypertrophy zone</u>: it is composed of large chondrocytes that accumulate glycogen. The matrix is compressed between the hypertrophied cartilaginous columns.
