Answer:
Blood
Explanation:
Connective tissue consists of extracellular matrix and cells. The main function of connective tissue is to bind the other tissues together, provide them support and strength. Blood is one of the liquid connective tissue that does not perform such functions. The presence of liquid extracellular matrix (plasma) and formed elements (blood cells) makes it a connective tissue. It serves in the transport of nutrients, gases, wastes, hormones, etc. It also takes part in immune responses but does not strength or support other body tissues.
When studying an earth worm, we could see all the amazing things God gave this creature and how it survives. If we dissect an earthworm, we will probably find out that it has multiple flexible parts that allow it to move around under ground. We could test this by filling a see through tank of some sort with dirt and water. We find an earthworm and let it stay in. We could examine that the worm stays on the surface for a little and than proceeds to its hole making. After a while, we could examine the tank and find that the dirt has many holes around it. Eventually let the worm go! This project could teach you something about worms. Worms are also helpful creatures. They provide the plants all the nutrients they need.

Answer:
A silent mutation is a mutation that is not observable effect on the organism's phenotype.
Explanation:
For example, if a base pair on a strand of dna got switched with another but the amino acid sequence remained the same, it is a silent mutation. Attached is a picture example. I hope this helped!
The astonishing similarity in the appearance of embryos from different animal species was observed as far back as the 19th century by scientists such as Karl von Baer, Charles Darwin and Ernst Haeckel. Such observations prompted the hypothesis that the individual development of an organism reflects its evolutionary history or phylogeny. Two groups of scientists, including researchers at the Max Planck Institute of Molecular Genetics in Dresden and the Max Planck Institute for Evolutionary Biology in Plön, have now succeeded in demonstrating, for the first time, that parallels exist between individual development and phylogeny on the level of gene expression.
Answer:
The development of refrigeration and frozen-food technology has benefited society in the following ways.
1) Refrigerator helps the people to protect the food substance from the infection of microorganisms such as bacteria and fungi.
2) Refrigerator helps in increasing the shelf life of many food materials. Some food substance have very short shelf life which can be increased by placing in the refrigerator.
Chicken sausages, nuggets and meat boll are the products that developed because of frozen -food technology.
