Agriculture is the science and practice of growing crops and rearing animals for human consumption. ... Farming is a more individual practice involving an area of land with buildings on it (as well as fencing, water facilities, etc.), that is used to grow crops and/or rear animals for human consumption.
Answer:
B, exoskeleton and antennae
Explanation:
I took vet prep, we learned about this. The bilateral symmetry is when you take two half's of an organism and each side looks the same. Both are like that with a bird and an insect is the answer is B.
Answer/Explanation:
(1) a mutation in the coding region, resulting in an inactive protein
To check to see if there is a mutation, you could extract the DNA from the cancer cells and then perform PCR to amplify the gene of interest. You could then perform sanger sequencing and compare the sequence to the normal gene to see if a mutation is present. To test the effect of the mutation, you would want to see if an active protein has been formed.
To see if a normal sized protein has been formed, you could perform a western blot, comparing the protein band to the WT protein band. If the protein is absent or much smaller, it is likely not a functional protein.
(2) epigenetic silencing at the promoter of the gene, resulting in reduced transcription.
To check for changes in the epigenetic landscape of the promoter, you could perform chromatin immunoprecipitation by extracting the chromatin from the tumour cells and using antibodies for different chromatin marks to see what has changed between the normal cells and the tumor cells. E.g. H3K9me3, H3K27me3. You would perform a pull down with the antibody of interest and then PCR for your promoter to specifically look at changes at that gene compared to normal cells. To test DNA methylation, you could perform bisulfite sequencing.
To see how transcription is affected, you could extract RNA from the tumor and normal cells, and compare the levels of RNA between the two samples by qRT-PCR
A Punnett square summarizes how the processes of meiosis and fertilization contribute to inheritance of different alleles of a gene. So one major advantage is it can help determine certain things about a child by looking at the dominant and recessive genes and gives a percent of how likely they are to get that thing for example a punnet square may show what color a child’s eye color is likely to be upon birth
A small town is located near a body of water and enjoys cooler temperatures than other areas in the same climate zone. This is an example of a microclimate
Explanation:
- The microclimate is nothing but experiencing a different temperature, which is restricted to a certain area only. It might be experiencing a lower temperature in comparison with the surrounding regions.
- The dry climate is experiencing a very high temperature and polar climate is nothing but a region where there are no warm summers and the temperature would be less than 10 degree Celsius.
- Climate zones are characterized by distinct parameters and these are found near the poles
