Answer:
Explanation:
Narrow sense heritability - h2
selection differential - S
Selection differential is calculated from the difference between the population average and the parental population.
Breeder's equation:
Response to selection - R = h2S
Mean milk production of 10% cows for experiment = 8.9L/hr
Mean milk production of parental population = 5.1L/hr
Selection differential S= 8.9 - 5.1 = 3.8 L/hr
Response to selection = 0.587 × 3.8 = 2.23
As a leaf cell is a plant cell contains chloroplasts for photosynthesis which the root hair cell does not have, leaf cell also contains larger vacuoles and the presence of a cell wall.
Answer: 2. endospores
An endospore is a structure that remains in the dormant state in some bacteria. The term endospore refers to the seed like form, but actually it is not a true spore. Endospore allows bacteria to restrain it's biological activities like obtaining food and reproduction under harsh environmental conditions like freezing and drying. Under favorable conditions these endospores reactivates. The endospore consist of bacterial DNA and ribosome.
Answer:
A
Explanation:
Intrusive igneous rocks cool from magma slowly because they are buried beneath the surface, so they have large crystals. Extrusive igneous rocks cool from lava rapidly because they form at the surface, so they have small crystals.
