Answer:
The protists refer to the unicellular eukaryotic species, which comprise algae, fungi, and protozoa. Of these some are autotrophs and some are heterotrophs. They exhibit the tendency to survive in aquatic surroundings because of their feeding habits.
In older approaches, protists are categorized on the basis of their morphology. However, by using novel approaches like molecular genetics, they are being categorized on the basis of their genetics.
It is like when you take a medicine you don't need, it becomes useless when you need it because your body can fight it off. So, I would have to say that the pesticides have been used on the bugs so much that they can finally fight it off. I really hoped I helped :D
Prescription medication is the least likely to affect the results and interpretation of a functional MRI.
Here are some of the factors that is most likely to affect the results of MRI :
- Caffeinated soda. Caffeinated soda tend to constrict the blood vessels in the brain, which will affect MRI results.
- cancerous growth, will create a huge shadow on MRI results
- sprained ankle, especially if it was fixed with metal bandage, will cause harm during MRI
Answer:
Proportion of the F2 male with red eyes and forked bristle will be 1/4
Explanation:
forked bristles are caused by an allele (Xf) that is X linked and recessive to an allele for normal bristles (X+).
Brown eyes are caused by an allele (b) that is autosomal and recessive to an allele for red eyes (b+)
A female fly that is homozygous for normal bristles and red eyes mates with a male fly that has forked bristles and brown eyes
X+X+b+b+ x Xfbb
the F1 gives 1/2X+Xf 1/2b+b
1/2X+Y 1/2b+b
intercross of F1
Proportion of the F2 male with red eyes and forked bristle will be
forked bristle= Xfy = 1/2 and for red eyes 2/4= 1/2 = 1/2x1/2 =1/4
Answer:
1. Location: Histosols are the soils which are found in the grasslands, swamps and marshes, whereas the aridosols are soils that are found in desert regions.
2. Color: Histosols are soils which are rich in organic matter therefore, are dark colored, whereas the aridosols are soils that lack organic matter, hence are light in color.
3. Water retention capacity: Histosols exhibit higher water retention capacity as compared to the aridosols.
4. Rate of decomposition: Rate of decomposition is higher in the histosols as compared to aridosols.
