Answer:
you can find the volume of an irregular object by immersing it in water in a beaker (or other container) with volume marks and see how much the level goes up.

Answer:
Immunity to Small Pox
Explanation:
Over the years, Europeans had built up an immunity to smallpox because many had contracted the disease and still survived. As the population grew children were born with some immunity to the disease. When the Europeans arrived in the Americas, and smallpox spread around the native peoples, the Europeans did not contract the disease because they were immune. However, since the natives were not immune, they slowly died of due just to the disease as well as some parts of the war between the europeans.
Answer:
Bacteria do not possess the tendency to withdraw sequences of introns from a gene, thus, if the gene for the human growth hormone were transcribed, it would translate into a non-functional protein.
When the expression of a gene takes place in eukaryotes, the budding mRNA comprising introns are removed consequently at the time of post-translational processing to produce mature mRNA. Also, the human growth hormone is produced by the pituitary gland in the form of a pre-hormone comprising a leader peptide of about 20 amino acids in length, which need to get removed post-translationally to produce a mature functional protein.
Bacteria do not possess the biochemical machinery either to effectively withdraw the leader peptide after translation or to splice out the introns. Thus, when an unchanged human growth hormone is cloned, the bacteria cannot produce the functional human growth hormone.
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.
Answer:
It can be hypothesized that fungal pathogen is responsible for decreased yield.
Explanation:
As the extensive heavy rain changed the climate of that area the soybean plant was effected by pathogenic fungus grown in the field. As we know that fungi makes spores that can withstand harsh environment. Humid and moist environment is favorable for fungi growth. So when spores find a suitable environment they grow rapidly. In the given example, the fungi was pathogenic that produced toxic compounds and effected the growth of soybean plant by damaging its root system and water supply to plant.
