Answer:
Skin, tears and mucus are part of the first line of defence in fighting infection. They help to protect us against invading pathogens.
Explanation:
can I have brainliest
Answer:
Punnet squares for maximum white mice are above, but H e t e r ozygous white mice aren't possible if black is dominant. Because black will be expressed, rather than white.
If white can be dominant and black can be recessive then h e t e r ozygous white mice are possible. (Punnet squares for this situation are also attached)
Answer:
Heterozygous (AB) for the STR locus = Allele (A) x allele (B) = 0.02 x 0.03 = 0.0006
Explanation:
The probability of the heterozygous genotype AB is equal to the product of the probabilities of these two independent events (i.e., independent events represented by allele segregation)= 0.02 x 0.03 = 0.0006
The horse and mouse are endotherms among them rat will have high mass-specific metabolic rate.
The shark and fish are endotherms among them fish will have high mass-specific metabolic rate.
Explanation:
The endotherm (heat requires in them to maintain internal temperature of the body) organism have high metabolic rates to maintain homeostasis, this requires the large amount of energy. Smaller animals have the greater surface area to volume ratio, hence more heat loss and higher metabolism. In larger animals body volume increases, surface area increase is also very slow, hence less heat loss and lower Metabolic rate. Smaller animals exchange oxygen to tissues at a high rate.
Same goes with ectotherms the larger the animal the smaller is the metabolic rate. During winters their activity slows down as they cannot adjust with the temperature of the surrounding.
However metabolic rates of ectotherm and endotherm cannot be compared.
Answer:
Decrease in large sharks; over fishing is a big concern; population in shark species declining; chopping off shark fins; sustainability is a challenge.
