395.2kcal
Explanation:
Given parameters:
Energy required to break one C-H bond = 98.8kcals
Unknown:
Energy required to break methane = ?
Solution:
The bond dissociation energy is the heat energy absorbed in breaking a covalent bond in the gas phase to its constituents elements.
Solving
CH₄ has 4 C-H bonds
To break 1 C-H bond, 98.8kcals of energy was used,
To break 4 of the bonds; 4 x 98.8kcals will be used = 395.2kcal

Large brain size, small and flat face, small jaws and teeth, exploitation of diversity are some common features of <em>homo </em>species. <em>Different</em><em> </em><em>homo </em>species have different shapes of skulls.
Homo, genus of the family Hominidae (order Primates), is distinguished by a relatively large cranial capacity, limb structure adapted to a habitual erect posture and a bipedal gait, well-developed and fully opposable thumbs, hands capable of power and precision grips, and the ability to make standardized precision tools by combining one tool with another.
<em>Different </em><em>Homo </em>species are differentiate from skull shapes. Their body shapes also tends to vary. This is due to different environment conditions in different time zones.
However,<em> Homo</em> species show many common characteristics such as Large brain size, small and flat face, small jaws and teeth.

. I think that bivalves have evolved to have smaller head regions because they have also evolved to have bigger shells or valves than cephalopod
Long term: I could either help a species have more genetic variation or wipe out an entire species. Short term: it could decrease food resources for other species.
The alula is a small structure that is found on birds. It is located at the joint between the hand wing and the arm wings of birds and it is the freely moving, first digit of a bird's wing. It is normally used by birds in slow flight. In humans, the structure that is comparable to the alula is the thumb.
