how does engineering impact the medical field give at least three examples
Answer:
Engineering has allowed for advancments in medicine far beyond what we thought was ever possible. One example is the ability to genomap, and from that new treatments and possibly cures for cancer are created. New tools are made that help in the everyday life of a medical provider, such as new clamps that can better grasp a vein or artery. Lastly, the development of new medicine through BioMed engineers has allowed for the treatment of kidney disease, and liver issues.

Answer: Is the level of genetic variation in the gametes related to the amount of DNA methylation observed?
Explanation:
The question 'is the level of genetic variation in the gametes related to the amount of DNA methylation observed?' is the MOST appropriate question raised by this observation.
Epigenetics refers to all changes in gene expression that are not associated with the DNA (nucleotide) sequence.Epigenetic modifications include DNA methylation, histone modifications (e.g., acetylation methylation, etc) and regulatory non-coding RNA pathways.The variation in the DNA methylation pattern may be associated with suppression (or activation) of gene expression.In conclusion, the question 'is the level of genetic variation in the gametes related to the amount of DNA methylation observed?' is the MOST appropriate question raised by this observation.

What kinds of data do scientists use to study climate?
Answer:
When scientists focus on climate from before the past 100-150 years, they use records from physical, chemical and biological materials preserved within the geologic record. Organisms (such as diatoms, forams and coral) can serve as useful climate proxies. Other proxies include ice cores, tree rings, and sediment cores.

What are the environmental and economical
uses of soil?
Answer:
Agriculture
Soil has vital nutrients for plants. As a result, it is used in agriculture to nourish plants. The roots of a plant receive nutrients from the soil to help it grow. The North Carolina Department of Agriculture and Consumer Services notes that 13 essential plant nutrients come from the soil.
Building
Soil is an important part of the building process. Soil compaction, which increases the density of the soil, is done as part of the building process. The purpose of the compaction is to improve the load support. If not done, structural failure can result. Soil can also be used as building materials such as adobe and red bricks.

Element Q is an element that has a metallic shininess, has good heat conductivity, and is very brittle. To which of the following categories does Element Q most likely belong? O A. compounds B. metalloids C. metals D. nonmetals
Answer:
C. metals
Explanation:
Elements in the periodic table are grouped into metal and non-metals depending on their characteristics. Metals usually possess the following characteristics:
- High melting and boiling point
- Brittle i.e. ability to break
- lustre i.e. ability to shine when polished.
- Good conductor of heat and electricity
Based on this above characteristics, element Q in this question is a METAL because it posseses the same qualities that a metal does.

Using the ecosystem model above, develop a constructed
response of whether energy can flow from each example listed
below. If energy does transfer, give an example
• animal to animal
•plant to animal
• animal to plant
•plant to plant
Answer:
Energy transfer in ecosystem follows the 10 % law.
Explanation:
In an ecosystem model, the transfer of energy starts with the base level that is from the grass level to the grasshopper that is the primary consumer. This is a plant to animal. The energy transferred from grasshopper to snake is an example of the animal to animal. The dead and decaying animal may transfer this energy back to the plant through the soil.Protein breaks down into
Answer:
amino acids
Explanation:
Proteins ingested in the diet are digested into amino acids or small peptides that can be absorbed by the intestine and transported in the blood.
Answer:
Mostly into carbohydrates and fats.
Explanation:
"They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. Amino acids are joined together by peptides, which are broken by proteases" - Protein Digestion: Enzymes, Absorption, and Ways to Improve

What is a dihybrid cross?Dihybrid is defined as the cross observed between two characters, in which two different gene is responsible for the two particular characters.
In the given question plant height and flower color are observed. A tall pea plant with red flowers (TtRr) is crossed with another tall pea plant with white flowers (Ttrr).
Gametes: TtRr - TR, Tr, tR, and tr
Ttrr - Tr, Tr, tr, and Tr
Genotypes: Tall, Red (T_R_) = 6
Tall, white (T_rr) = 6
Dwarf, red (ttR_) = 2
Dwarf, white (ttrr) = 2
Therefore, the probability of getting dwarf plants with red flowers in the F1 progeny is 1/8 or 12.5%.

Which amino acid sequence is coded for by the mRNA segment AUG-CCC-CAC-GAA-UAC?
Answer:
Met-Pro-His-Glu-Tyr
Explanation:
To discover what each amino acid sequence codes for, we have to look at a codon chart, a chart with all the possible amino acid combinations and what they code. After analyzing it, we can see that the sequence AUG codes for the amino acid methionine, CCC codes for the amino acid proline, CAC codes for the amino acid histidine, GAA codes for the amino acid glutamine, and UAC codes for the amino acid tyrosine.

When your drawings are complete, add any additions to make them like a comic strip you find in a newspaper. You can include dialogue between the cells or headlines for each picture. You can make your strips funny, dramatic, scary, or any other appropriate style you want.
Binary fission is a type of asexual reproduction observed in bacteria, in which one cell divides into two daughter cells.
What is binary fission?During binary fission, there is no involvement of two parents and also there is no gamete formation occurring, so it is categorized into asexual reproduction.
There are several steps during binary fission, firstly bacteria replicates its DNA, secondly, it grows and increases the number of a cell organelle, now it segregates DNA into two parts, at the end splitting this large cell.
In DNA replication bacteria uncoils its chromosome and copy this genetic information to transfer it to subsequent generations.
Therefore, replication, cell growth, segregation, and splitting of the cell are stages of binary fission.
