Answer:
Combined parenting leads to faster reproduction
Explanation:
Genetic diversity or variations in the physical appearance of organisms is caused by genetic or environmental factors. Reproduction brings about variation through gamete formation, fertilization and mutations.
During prophase 1 of meiosis, homologous chromosomes pair to form bivalents. The crossing over at the chiasmata results in new gene combination and variations.
Fertilization permits parental genes to be brought together. This causes variations in members of the same family.
Mutation is the spontaneous change in genetic make-up. These changes may be inherited by offspring bringing variations. However, combining parenting does not increase genetic diversity.
Answer:
Meiosis
Explanation:
Mitosis creates an identical set of daughter cells to the parent cells through asexual reproduction but meiosis creates a set of sex cells that are identical to each other but not to the parent cell and this is through sexual reproduction.
Answer:
Statement B is false.
Explanation:
PKA and PKG is both have binding domains to attach with nucleoside monophosphate and help in modulating these enzymes that explains that PKA is more related to the PKG than PKC at the level of amino acid.
At the level of polypeptide chain level PKG has single polypeptide chain whereas in PKA modulatory domains are located on different poly peptide chain. Both are activated by the nucluoside triphosphate, more precisely PKA by cAMP and PKG is by cGMP respectively, whereas PKC is activated by DAG or Ca or both depending on the isofom.
Thus, the correct answer is - option B.
Monthly mean temperature of oceanic climates should be below 22°C in the warmest months. Hottest month is on July. From the options, the location most likely situated near the ocean should be A. It's not B or D since it has 18°C. Not C as well as the interval of temperatures seems to be offset, and it should be colder as it approaches October.
Answer:
Bees are perfectly adapted to pollinate, helping plants grow, breed and produce food. They do so by transferring pollen between flowering plants and so keep the cycle of life turning.
The vast majority of plants we need for food rely on pollination, especially by bees: from almonds and vanilla and apples to squashes. Bees also pollinate around 80% of wildflowers in Europe, so our countryside would be far less interesting and beautiful without them.
