Answer:

A lesion in the Broca's area of the brain would most likely result in a disruption of language comprehension and expression.

Explanation:

There are two parts of the brain that are linked to speech.

Wernicke's area also called Wernicke's speech area and
Broca's area.

Wernicke's Area is wired for the comprehension of written and spoken language while Broca's area adapted for in the production of language.

Broca's area, which is located in the frontal lobe of the brain, is connected to the production of speech.

A recent study showed that it also plays a significant role in the comprehension of language. Working memory and the Broca's area both function simultaneously to allow a person to express themselves verbally.

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>

A hypothesis is a general principle or explanation that is derived from observations. Suppose you make the following observation

mr_godi [17]

Question continued

For each statement below, mark "True" if it would be a valid hypothesis, based on these three observations alone, and mark "False" if it would not be a valid hypothesis.

1. The onion cells I looked at have a nucleus.

2. All onion cells have a nucleus.

3. All cells have a nucleus.

4. Some cells have a nucleus.

5. Only onion cells have a nucleus.

6. If I look at 10 skin cells from my hand, each one will have a nucleus.

Answer:

1. The onion cells I looked at have a nucleus. false - this is not a hypothesis, it is an observation of the evidence you collected.

2. All onion cells have a nucleus. true - this is a valid hypothesis based on the evidence you have gathered from looking at onions

3. All cells have a nucleus. true - this is a hypothesis based on you looking at 3 cell types, several samples of each, and finding that they all have a nucleus

4. Some cells have a nucleus. false - this is not a valid hypothesis. Your evidence so far suggests all cells have a nucleus

5. Only onion cells have a nucleus. - false, you know this to be false as other cell types you analysed had a nucleus

6. If I look at 10 skin cells from my hand, each one will have a nucleus. false - a hypothesis is supposed to be a general principle that is backed up by evidence, this is too specific.

Advantage amoeba has over a cell of a lizard in relations to their levels of organism

nignag [31]

Amoebas are single-celled organisms, which means that they are composed of just one cell. Each amoeba is a cell capable of performing all living functions by itself. They can reproduce asexually. They are protozoans with no fixed shape. Most have no hard parts and look like blobs of jelly.

Ilya [14]

Answer:

A. Cystic fibrosis deaths should be more common in the regions with tuberculosis.

Explanation:

Cystic fibrosis is a type of genetic disorder which affects the lungs mostly. Its long-term symptoms include uneasy breathing and coughing up mucus from lung infections. Therefore, In a place where tuberculosis is predominant, cyctic fibrosis death will rise.

Billy and Johnny are brothers, but they do not look alike. Which one of the following pairs of factors contributed to this genet

jekas [21]

Answer:

C- Crossing Over

Explanation:

Crossing over is essentially the gene shuffling and swapping around of genetic information.

A- is false because mitosis describes the building of nonsexual cells. So in terms of genetics, meiosis is the one you're looking for in this scenario.

B- Brothers are not clones.

D- Your parents had to have sex to produce a child. This is not Asexual.
