<span>Endothermic reactions take in heat from the environment in order to react while exothermic reactions release heat during the reaction. For this, D must be true as the products have less energy because they have released heat during the reaction. A and C are incorrect because they products and reactants are equal and B is wrong because the energy of the products would be more as the reaction took in heat.</span>
Answer:
The volume occupied by molecules becomes a significant part of the total volume.
Attractions between molecules cause a reduction in volume.
Explanation:
C is wrong. The masses of molecules are constant.
In sexual reproduction the offspring has similar genetics and look of those of the parents. In asexual reproduction, it will look like the one parent, but it won't have the parent. The parent would have split in two and created two daughter cells, but when they make buds of them they have one child and on parent. Hope I helped! ;)
Answer:
S. aureus strain is less infectious, but its alpha-toxin is highly-toxic.
Explanation:
Given data:
LD50 for S. aureus alpha toxin 0.45 \mu g/kg
ID50 for same mouse density found to be 200,000
From the data information given above Staphylococcus aureus was done on mice. The result show that LD50 is found to be 0.45\mu g/kg and ID50 found to be 200,000 on same mouse population
the result taken together mean that S. aureus strain is less infectious, but its alpha-toxin is highly-toxic.
