Joe has suffered a massive stroke. Since then, he has started repeating many of his actions through the day. He brushes his teet

h many times in the morning and takes a shower many times before bedtime. This is because he is unable to retain any memories of his actions. In the context of the organization of the brain, these behavioral symptoms are most likely due to a damaged _____________.

Answer:

The given blank can be filled with hippocampus.

Explanation:

One of the components of the brain, the hippocampus, is found in the bottom middle part of the brain's inner folds, known as the temporal lobe. The primary functions of hippocampus comprise memory and human learning. It is the component of the limbic system that is related to the functions of reacting and feeling.  

In case if one or both the components of the hippocampus get destructed due to an accident or due to an illness like Alzheimer's disease, the person can encounter the loss of memory or with the loss of the tendency to produce new and long-term memories. Destruction to the hippocampus can make it tough to remember things.

n the Meselson-Stahl DNA replication experiment, if the cells were first grown for many generations in 15N containing media, and
nirvana33 [79]

Answer:

50%

Explanation:

DNA replication is a semi-conservative process. It means that after DNA replication, the newly formed DNA molecules have one parental strand and one newly formed strand. The cells in the experiment have DNA with 15N. After one round of DNA replication, each DNA molecule would have one parental DNA strand with 15N and one newly formed DNA strand with 14N.

However, after the second round of DNA replication, each hybrid DNA with strand having 15N and the other with 14N would be unwound. The parental heavy DNA strands would be present in the 50% of the newly formed DNA while the rest 50% of DNA molecules would have both strands with 14N (both light strands).

A Xw+m+Xwm female was mated to a XwmY male. Out of 1000 total F1 progeny there were 230 flies that were otherwise wild type with
deff fn [24]
In order to calculate the distance between two alleles/genes that are found in the same chromosome, we need to know how often crossing-over happened (recombination frequency). We know from the text that white eyes were linked to miniature wings and that wild type eyes were linked to wild type wings, so any phenotype that's contrary to these parent combinations are a result of crossing-over. We know then that 230 flies + 240 flies were a result of such recombination. To calculate the recombination frequency we only need to divide these flies (total of recombinant flies) by the total of flies in the offspring and turn it into percentage.
\frac{230+240}{1000}=0.47
0.47*100%=47%
47 map units is the distance between the genes <span>for eye color and wing length.</span>

Which freshwater source is a permanent shallow body of water with plant life throughout? lake pond reservoir wetland
Svetllana [295]

Answer:

Pond

Explanation:

Ponds are inland water bodies that are usually smaller in surface area than a lake and nonflowing in contrast to rivers or streams. However, a pond is a shallow freshwater source that inhabits organisms' life (plants and animals alike).

Due to the shallow state of a pond, light penetrates to the bottom, hence, allowing the constant growth of plant life. Therefore, PONDS are freshwater sources that contains a permanent shallow body of water with plant life throughout.
