What are the abiotic factors that could affect a population?
Which region of the Ig molecule interacts with the antigen? What makes the region suited for this purpose?
Answer and Explanation:
Immunoglobulins (Ig) are proteins that are composed of 4 polypeptidic chains: 2 heavy chains (H) and two light chains (L). They assemble in a structure with a 'Y' form. This structure has two regions: the Fab region and the Fc region.
The region of Ig which interacts with the antigen is the Fab region. That is possible because the Fab region presents variability in the amino acid sequence which determines the specific complementary shape with the antigen structure (like a lock and the key).
According to the endosymbiotic theory of the origin of eukaryotic cells, how did mitochondria originate?
a) when a protoeukaryote engaged in a symbiotic relationship with a protocell
b) from infoldings of the plasma membrane, coupled with mutations of genes for proteins in energy-transfer reactions
c) from the nuclear envelope folding outward and forming mitochondrial membranes
d) by secondary endosymbiosis
e) from engulfed, originally free-living proteobacteria
Answer:
e) from engulfed, originally free-living proteobacteria
Explanation:
The bacterium was captured by a eukaryotic cell and then the cell evolved into the mitochondria we know today!
According to the endosymbiotic theory of the origin of eukaryotic cells, mitochondria formed from engulfed, originally free-living proteobacteria. The correct option is e.
What is proteobacteria?Proteobacteria are a major phylum (group) of bacteria. Pathogens such as Escherichia coli, Salmonella, Vibrio cholerae, Helicobacter pylori, and many others are among them.
Others are free-living, and they include many of the bacteria that fix nitrogen.
Proteobacteria, which includes mesophilic and neutrophilic bacteria, is the second largest phylum of hydrogenogenic CO oxidizers. Members of this phylum can be found in a variety of classes.
According to the endosymbiotic theory, mitochondria and chloroplasts were once free-living bacteria that were phagocytized but not digested by another cell.
According to the endosymbiotic theory of eukaryotic cell origin, mitochondria evolved from a rickettsia that was phagocytized but not digested by the larger cell.
Thus, the correct option is e.

Fisherman in a certain region have noticed a significant decrease in the biodiversity of fish species present in a local body of water. This has caused a decrease in the variety of fish available for consumers in the region. Which of the following changes has most likely caused this change in biodiversity?
A.
an increase in fish reproduction rates
B.
the introduction of an invasive species
C.
a decrease in water pollution
D.
a prolonged period of increased rainfall
Answer:
B
Explanation:
The introduction of an invasive species makes sense, because invasive species can wipe out mulitple native species leaving less resources for the native fish, and thus, decreasing biodiversity. A great real life example of this would be the Lionfish.

What happen to the brain and the brain cavity?
Answer: OK so The ventricles of the brain are a communicating network of cavities filled with cerebrospinal fluid (CSF) and located within the brain parenchyma. The ventricular system is composed of 2 lateral ventricles, the third ventricle, the cerebral aqueduct, and the fourth ventricle (see the images below).Survival in untreated hydrocephalus is poor. Approximately, 50% of the affected patients die before three years of age and approximately 80% die before reaching adulthood. Treatment markedly improves the outcome for hydrocephalus not associated with tumors, with 89% and 95% survival in two case studies

The cranial cavity, also known as intracranial space, is the space within the skull that accommodates the brain. The skull minus the mandible is called the cranium. The cavity is formed by eight cranial bones known as the neurocranium that in humans includes the skull cap and forms the protective case around the brain.
