spiders
Explanation:
While humans and many other species have red blood, due to the iron in their hemoglobin, other animals have different colored blood.

Explanation:
Infants’ bodies contain more water (75%) than those of older humans. Their kidneys are not fully mature yet thus they excrete more diluted urine. This cause easy dehydration and a higher risk of illness for infants. Infants are less resistant to heat since their thermoregulatory systems are not as developed. Parents and caregivers must see to it that infants are provided water for their hydration.
Answer:
The rate would increase.
Explanation:
Activation energy is the energy needed for a chemical reaction to start while the rate of reaction is how a reactant turns into the product. Catalysts are used to speeden up the rate of a chemical reaction.
The catalyst do this by lowering the activation energy needed for the reaction to occur, leading to the increase in the rate at which the same reaction occurs. It should be noted that a catalyst is not a reactant, neither does it get used up in the chemical reaction. It just provides an alternative energy pathway with a reduced activation energy, hereby, helping the reaction to proceed faster than it would without the catalyst.
Answer:
D. all of these.
Explanation:
All of these are the questions that involves ethical considerations because the method used in these questions are not doing naturally. Vitro fertilization is the fusion of woman's egg with the sperm of male outside the uterus of women which is unethical.
