DM occurs when the body cannot produce enough insulin or cannot respond appropriately to insulin. Insulin is a hormone that the body needs to absorb and use glucose (sugar) as fuel for the body’s cells. Without a properly functioning insulin signaling system, blood glucose levels become elevated and other metabolic abnormalities occur, leading to the development of serious, disabling complications.
Many forms of diabetes exist. The 3 common types of DM are:
Type 2 diabetes, which results from a combination of resistance to the action of insulin and insufficient insulin production
Type 1 diabetes, which results when the body loses its ability to produce insulin
Gestational diabetes, a common complication of pregnancy. Gestational diabetes can lead to perinatal complications in mother and child and substantially increases the likelihood of cesarean section. Gestational diabetes is also a risk factor for the mother and, later in life, the child's subsequent development of type 2 diabetes after the affected pregnancy.
Answer:
B.
Explanation:
I think it's because protons are the ones that circle, neutrons stay in the middle becuz they're neutral, and electron are negatively charged?
Answer:
150
Explanation:
According to the given information, the pink-flowered plant (Rr) is crossed with a red-flowered plant (RR). The pink-flowered plant would make two types of gametes: 1/2 with "R" and 1/2 with "r".
The red-flowered plant would make all gametes with "R" allele. The random fusion of these gametes gives pink and red-flowered progeny in 1:1 ratio.
Since 50% of plants of the progeny are red-flowered, out of 300 offspring, the total red-flowered plants would be= 50 % of 300 = 150.
Answer:
There are different evidences for evolution that includes anatomy, fossils, molecular biology and biogeography.
Molecular biology uses DNA and protein sequences that the genetic code reflect the shared ancestry of life. DNA comparisons used for the anatomical evidence.
All living cells are organized in the same basic DNA and use the same genetic code. Proteins derived from genes, all originate from the same set of amino acids. Comparing parts of DNA in various species has shown that even very different organisms still have significant parts of similar DNA. For example, in chimpanzees and humans have some precent of same genetic structure. In the amino chain, chimpanzees and humans have only one position, while humans and moths have 31 different positions.
<u>There are different advantages and disadvatages of each type of evidences are:</u>
Advantages:
- Anatomy share information about the similar physical structures shared by common ancestor (homologous structures)
- Fossils provide information about the extinct species.
- Molecular biology provide genetical relationship between organisms.
- Biogeography share global organism distribution and island species unique characteristics reflect evolution and geologic change.
Disadvantages:
- some of the structures such as forelimbs of human and birds seems homologous in structure as per comparative anatomy but they have evolved independently in each species.
- Fossils are impressions of past living organism and buried in earth surface rom long geological past, hence during this geological time there can be many changes in the fossil structure and can manipulate the evidences.
- Molecular biology has disadvantage of lack of assay specificity and sensitivity.
- organism can evolve and adapt according to different condition, hence Biogeography can not exactly tell the exact changes in the characteristics of organisms on the basis of particular geology.
