The correct option is this: HAS THE CLAIM BEEN TESTED NUMEROUS TIMES BY MORE THAN ONE SCIENTISTS.
For a claim to be accepted has been valid in the science world, it must have been tested several times by many scientists who obtain the same results. Having a uniform result about a phenomenon is usually considered an important factor when examining the validity of a claim.
Answer:
Option A. can reproduce by budding.
Explanation:
Sponges is a multicellular organism which consists of pores that allows water to move through the body. Sponges belongs to kingdom animalia and phylum porifera. Sponges can reproduce by budding. Sponges are placed in kingdom animalia because they are unable to make their own food, made of more than one cell and absence of cell wall.
Answer:
D. A silent variant near the 5' end of the TBX1 gene.
Explanation:
TBX1 gene is wild type human being. It gives instructions for making protein called T-box 1. It plays an important role in tissue formation and organs during embryonic development.
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.
