In studying the brain of this monkey you discover that the brain is almost 10% larger than you would expect for primate of this size.

6. What parts of the brain do you most expect to be enlarged and why?

a) What are the disadvantages of this increase in brain size?

b) If the increase is primarily in the prefrontal cortex and V1 area, what advantage would it provide?

c) for increase in the ventral premotor area, what advantage would it provide for the monkey?

Expert Solution

6. It's the cerebrum. With evolution the brain development is marked by the enlargement of the cerebrum which make the organism more advanced than the preforms.

a) the increase in brain size has provided some disadvantage that the head size need to be increased for adapting a big brain. The pressure inside the brain also increases. So there are chances for an external injury to affect the brain so fast.

b) in frontal cortex enlargement will helporenin the emotion and expression. The memory will increase. Language, judgement and sexual behaviour increases.

In the development of V1 area the brain will make a correct coordination about the visual fields. It helps in understanding the size and depth of the image formed and helps in understanding the specif features of the image formed.

c) this helps the monkey too make exact movements with the muscle according to the motor stimulation. The muscle cordination increases.

You discover an organism with a new mutation in the gene that you are studying that...

You discover an organism with a new mutation in the gene that you are studying that changes the codon in the mRNA from a GCC (Ala) to a GAC (Asp) causing a mutant phenotype. You feed this organism a mutagen and find that in one of its progeny the phenotype has now reverted back to wild-type. When you look at your gene in this offspring you find the mutation GAC (Asp) has been changed back to the original GCC (Ala)....

25.You are studying a new type of cancer and you discover that there is a mutation in a gene that encodes a histone acetylase. You hypothesize that the mechanism by which this mutation causes cancer is: A – Introducing random mutations B – By altering the expression of a gene involved in the control a cell proliferation C – Mutating DNA repair genes D – By introducing a mutation in a gene involved in the control a cell proliferation 26.Often...

Suppose you wish to be outstanding in your field by studying plant cell biology. You discover a new strain of wild lima bean plants from Costa Rica that is resistant to being killed by a hydrophobic pesticide. Which one of the following states the most reasonable hypothesis that could explain the nature of the pesticide resistance? A) Many chloroplast proteins are encoded in the plant nuclear genome. A nuclear gene encoding an enzyme involved in the dark reactions might confer...

9. You are studying cuttlefish and you observe that females mate primarily with larger males. You suspect that sexual selection may be influencing male size. 9a. Place a check (√) next to the pieces of information provided by your existing observations and place an X next to missing information you still need to be certain sexual selection is operating: ____Trait variation in males ____Trait variation in females ____Fitness differences in males ____Fitness differences in females ____Variation in the male trait...

You are studying the part of the brain that mediates stress. You have treated some mice under stressed conditions and you also have control mice. You isolate the appropriate brain regions from both groups. Describe what you would do to identify changes in genes associated with acetylated lysine 9 on histone H3. What would you do to prepare the brain samples for analysis? Would technique would you use to purify genes associated with aceylated lysine 9 histone H3 and how...

Question 29 options: A researcher is studying the effectiveness of a new “brain training” game for Android phones, which the game’s developer says can improve memory. The game involves watching a series of cartoon animals run across the screen and tapping whenever the same animal appears twice. The researcher designs an experiment in which 20 participants (the memory group) play the game for 1 hour a day for a week. Another 20 participants (the non-memory group) plays a game with...

Is it possible for a monkey to create a 10-year portfolio return that exceeds the market rate of return? Explain. Is a portfolio return in excess of the market rate a signal of successful portfolio management? Explain.

10] You are studying the inheritance of three genes in the scorpion fly Panorpa communis. You have identified three different autosomal recessive traits, lavender eyes, green body and pointed wings. These phenotypes are caused by alleles in thee different genes, x, y, and z respectively. Wild type flies have red eyes, brown body, and straight wings (x+, y+ and z+). You cross two different pure breeding and obtain a wild-type F1. You then cross the F1 to a true-breeding line...

You are a researcher that is studying a population of dragons. You have been studying the dragons for many years and think that this population has some individuals that have some genetic abnormalities that could be the result of 1) DNA replication and repair errors, 2) chromatic packaging issues or 3) chromosomal mutations. These abnormalities seem to run in families and do not appear to be affected by seasonal or environmental changes but do cause the individuals to get ill...
