I would recommend at least 10 pounds because average baby weight is 7 lbs
I'm not sure how exactly you wanted this question to be answered. You're either talking about the symmetry where animals would have two legs or two arms for example and thus producing a pair of each muscle on both sides of the body, or you're refering to the development of agonistic and antaonistic muscles where each of them served a different purpose; either extending or contracting.
Answer:
a. Damage is caused by free radicals that slow down the cell-duplication process.
c. Aging may be caused by the inevitable loss of the ability of cells to duplicate perfectly.
Explanation:
The free radical theory of aging states that aging is caused by accumulation of damage inflicted by reactive oxygen species (free radicals). It proposes that organisms age because they accumulate oxidative damage, Now,this damage comes from reactive oxygen species (ROS), which are partially reduced metabolites of molecular oxygen (free radicals) generated as products of metabolic reactions. Thus, these free radicals cause damage that slow down the cell-duplication process.
Also, Aging may be caused by the inevitable loss of the ability of cells to duplicate perfectly. (SENESCENCE).
When senescence occurs (i.e inevitable loss of the ability of cells to duplicate perfectly) there is progressive deterioration of physiological function, an intrinsic age-related process of loss of viability and increase in vulnerability of cells.
Answer:
The correct answer is A.
Explanation:
If i were assigned the task of producing a cladogram (a diagram used by scientists to compare different species and the relationships between them) that represents the evolutionary relationship between the given species, as the shared derived trait for the cladogram i could use the presence of a jaw which all of the mentioned species possess.
Shark and Lizards do not have hair, give birth to live young does not apply to lizards and sharks as well which lay eggs, production of milk is also not present in any other than humans, gorillas and tigers.
I hope this answer helps.
