Subtle anatomical differences between each hemisphere in the brain is called:
a) lobular specialization
b) global differentiation
c) hemispheric lateralization
d) cranial integration
e) apraxia
Answers
The subtle anatomical differences between each hemisphere in the brain is called hemispheric lateralization.
This means that each hemisphere has its own specific functions, such as the left hemisphere being responsible for language and logical reasoning, while the right hemisphere is more involved in creativity and spatial awareness. This lateralization allows for efficient processing and specialization of different cognitive tasks.
On the other hand, apraxia is a disorder that affects the ability to plan and execute purposeful movements, usually caused by damage to the brain's motor centers. It is not directly related to hemispheric lateralization but can impact both hemispheres depending on the location and extent of the damage.

Answers
People's basic survival instincts such as fear, aggression, hunger, and sex are associated with the primal part of our brain known as the limbic system.
The limbic system is responsible for regulating our emotions, motivation, and instincts necessary for our survival and propagation as a species. Fear and aggression are two instinctual responses that help us protect ourselves from danger and potential harm, while hunger and sex are crucial to our survival as they drive us to seek food and reproduction.
The limbic system interacts with other parts of the brain, such as the prefrontal cortex, to regulate and balance our emotional responses. It is important to note that while these instincts are necessary for survival, they can also be influenced and modified by social and cultural factors. Thus, our behavior is not solely driven by our primal instincts but also shaped by our environment and experiences.
Understanding these basic survival instincts can help us better comprehend human behavior and motivations, and how they can influence our decision-making processes.

Which of the following organisms is a heterotroph? a) Rose b) Pine tree c) Deep-sea tubeworm d) None of these
Answers
Since the given organisms prepare their own food, hence none of the organisms mentioned are heterotrophs. Thus, the correct answer is Option D.
Heterotrophs are organisms that depend on other species (plants and animals) for food since they are unable to prepare it for themselves. They are dependent on these producers for food, either directly or indirectly.
The rose and the pine tree, two of the choices given, are both autotrophs since plants can make their own food through photosynthesis. On the other hand, the deep-sea tubeworm is a chemoautotroph, meaning it gets its energy from inorganic substances in its surroundings.

Decide whether sarcodines are more like ciliates or sporozoans. Explain
Answers
Answer: Sarcodines are more like ciliates than sporozoans. Sarcodines are a diverse group of single-celled organisms that are characterized by their ability to move using pseudopods, which are temporary extensions of their cytoplasm. This feature is similar to ciliates, which also move using cilia or pseudopods.
On the other hand, sporozoans are a group of parasitic single-celled organisms that are characterized by their lack of ability to move on their own. Instead, they rely on a host organism for transportation. This lack of mobility sets sporozoans apart from both ciliates and sarcodines.
Another difference between sarcodines and sporozoans is their method of reproduction. Sarcodines reproduce through binary fission, which is a type of asexual reproduction. In contrast, sporozoans reproduce through sexual reproduction that occurs within the host organism.
In conclusion, sarcodines are more like ciliates in their ability to move using pseudopods and their method of asexual reproduction. This makes them distinct from sporozoans, which are parasitic and lack the ability to move on their own.
Explanation:
Answer:
Sarcodines are more similar to ciliates than sporozoans. Sarcodines are a group of single-celled organisms that move using pseudopodia, which are temporary extensions of their cytoplasm. Ciliates are also single-celled organisms that move using cilia, which are hair-like structures on the surface of the cell. Both sarcodines and ciliates are similar in that they move using extensions of their cytoplasm and they both belong to the kingdom Protista.
On the other hand, sporozoans are a group of parasites that do not move using pseudopodia or cilia. Instead, they are immotile and rely on vectors such as insects to move from host to host. Sporozoans belong to the phylum Apicomplexa and have a very different life cycle compared to sarcodines and ciliates.
In summary, sarcodines are more similar to ciliates than sporozoans because they both move using extensions of their cytoplasm and they belong to the same kingdom (Protista).

a. Primula kewensis, with its 36 chromosomes, likely formed from chromosome quadrupling of P. floribunda with its 9 chromosomes.
b. Primula kewensis likely formed from the hybridization and subsequent chromosome doubling of a cross between the other two species.
c. Primula kewensis, with its 36 chromosomes, likely formed from chromosome tripling of P. floribunda with its 12 chromosomes.
d. Primula kewensis likely formed from the hybridization from a cross between the other two species.
Answers
The statement that best describes how P. kewensis likely arose from P. floribunda and P. verticillata is that "Primula kewensis likely formed from the hybridization and subsequent chromosome doubling of a cross between the other two species."
Explanation:
Primula kewensis is a sterile hybrid of Primula floribunda and Primula verticillata. It is a hybrid of two diploid species with 18 chromosomes, each containing two haploid sets (2n = 18). The resulting hybrid, Primula kewensis, is sterile and triploid, with 36 chromosomes (3n = 36).Primula kewensis, with its 36 chromosomes, likely formed from the hybridization and subsequent chromosome doubling of a cross between the other two species. P. kewensis, with its three sets of chromosomes, is sterile, and it arose as a result of the hybridization of P. floribunda and P. verticillata. The hybridization produced a sterile offspring that was initially a tetraploid, with four sets of chromosomes. Chromosome doubling in the sterile tetraploid hybrid would have resulted in a fertile triploid hybrid with three sets of chromosomes, which is Primula kewensis.The chromosome number for Primula floribunda (2n = 18) and P. verticillata (2n = 18) is diploid, whereas the chromosome number for Primula kewensis (3n = 36) is triploid. Chromosome doubling in the sterile tetraploid hybrid would have resulted in a fertile triploid hybrid with three sets of chromosomes, which is Primula kewensis.Therefore, the statement that best describes how P. kewensis likely arose from P. floribunda and P. verticillata is that "Primula kewensis likely formed from the hybridization and subsequent chromosome doubling of a cross between the other two species."

(b) To genetically engineer the original cell so that it would glow, the scientists had to obtain a suitable
gene.
(i) Describe the stages that a scientist would complete to obtain this gene.
Answers
Answer: See Below
Explanation:
1. The scientist would need to identify the gene for a protein that would make it glow. For example Aequorea victoria, the jellyfish that produces green fluorescent protein (GFP) is the most common type of fluorescent tag use in biotechnology. This would be done by completing genetic sequencing to identify the gene of interest from the jellyfish cell.
2. The gene could then be amplified through PCR. Assuming this is a bacterial cell, a vector such as pUC19 could be used. The vector and the PCR amplified product would have to be digested. A double digest is recommended to ensure the gene inserts in the proper conformation.
3. Heat shock the plasmid into the cell and proceed on to Blue/White screening to identify which cells contain the gene of interest. You can then isolate and grow the culture containing the GFP gene and induce with IPTG to produce the protein that would make it glow.
Alternatively you could buy a pre-made plasmid from AddGene containing the GFP gene for 75$, complete a miniprep on the cells and heatshock. Either way works.

Explanation:
A population of butterflies has an intrinsic rate of increase of 0.64 but a growth rate of 0.36.
Calculate the carrying capacity of the butterflies when they start with 30 of them.
Answers
Answer:
-2.28
Explanation:
The intrinsic rate of increase is the maximum rate of population growth that can be sustained by a species in the absence of limiting factors, such as competition for resources or predation. The growth rate is the actual rate of population growth that is observed in a population. The carrying capacity is the maximum population size that can be sustained by a given environment.
To calculate the carrying capacity of the butterfly population, we need to use the formula:
K = r / (K - r)
Where K is the carrying capacity, r is the intrinsic rate of increase, and K is the growth rate.
In this case, the intrinsic rate of increase is 0.64 and the growth rate is 0.36. Plugging these values into the formula, we get:
K = 0.64 / (0.36 - 0.64)
K = 0.64 / (-0.28)
K = -2.28

Answers
The dissolution of an eggshell in an experiment typically takes several days rather than just 24 or 48 hours. However, after 24 hours, you might observe some changes, such as the appearance of bubbles or a slight softening of the shell. After 48 hours, further softening and visible degradation of the shell might be evident.
How to explain the experimentIn the first portion of the experiment, the two molecules involved in dissolving the eggshell are acetic acid (vinegar) and calcium carbonate. Vinegar contains acetic acid, which reacts with the calcium carbonate in the eggshell, resulting in the formation of carbon dioxide gas and calcium acetate.
When the egg is placed in tap water, the concentration of water is greater outside the egg. The tap water has a higher concentration of water molecules compared to the interior of the egg.
When the egg is placed in corn syrup, the concentration of water is greater inside the egg. Corn syrup has a lower concentration of water molecules compared to the interior of the egg.
