Approximately one-quarter or 25% of the homeless population are adults with a severe mental illness, facing substantial health risks and a lower average life expectancy.
Adults with chronic mental illness account for approximately one-quarter of the homeless population. Specifically, about 25% of homeless individuals in U.S. shelters have a severe mental illness. This significant percentage indicates that the homeless population is at a much greater risk for a range of physical and mental health problems compared to the housed population.
Moreover, the homeless are more likely to experience hunger, food insecurity, and are up to twenty times more prone to chronic illnesses such as hepatitis, high blood pressure, and tuberculosis. Furthermore, the average life expectancy for homeless adults is around the mid-fifties, which is about twenty years shorter than that of housed adults.

Explanation:
When habitats are destroyed, specialized species are more likely than generalized species to _____.
adapt to change
migrate to new habitats
move into a new niche
become extinct
Answer: become extinct
A generalist species is able to thrive in a wide variety of climate and environmental conditions and have varied diets. When their habitats are destroyed, they can easily adapt to change, migrate or move into a new niche.
A specialist species can thrive only in a narrow range of climate and environmental conditions and has a limited diet. When this environment or habitat is destroyed, they are most likely to become extinct than the generalist species.
Answer:
become extinct

Two homologous sets of genes" can mean either two similar collections of genes coming from your two separate parents or two similar collections of genes arranged on two complete sets of chromosomes
Final answer:
Homologous chromosomes are pairs of chromosomes that contain the same genes in the same order, but may have different alleles, leading to genetic diversity. Individuals inherit one chromosome from each parent, which contributes to traits like blood type or dimples, and can result in homozygous or heterozygous genotypes.
Explanation:
Understanding Homologous Chromosomes
When we speak of 'two homologous sets of genes,' we are referring to two related sets of genes that define our hereditary traits. Each person receives 23 chromosomes from each parent, for a total of 46. These chromosomes come in pairs, one from the mother and one from the father, and thus are described as homologous. Homologous chromosomes have the same genes arranged in the same order; however, they may carry different alleles, which are variations of these genes.
These different alleles contribute to the genetic diversity in humans. For instance, if we consider the gene responsible for blood type, a person may inherit two identical alleles, which would make them homozygous (e.g., AA, BB, OO), or two different alleles, making them heterozygous (e.g., AB). Genetic inheritance plays a crucial role starting at conception when the sperm and egg cell unite, each donating 23 chromosomes.
A straightforward example is the trait for dimples; a child can inherit the allele for dimples from one parent and an allele for no dimples from the other parent. This demonstrates how homologous chromosomes can carry different genetic information that affects the same trait and how this variation results in the diverse characteristics we observe.

A. what role does mrna play in the flow of information in the cell? (hint: remember the central dogma of molecular biology.) please include the basic flow of information in the cell.
The tendency for one extreme phenotype, such as large size or extreme coloration, to be favored over average phenotypes is called
The answer is disruptive selection. The allelic frequency of the population shifts to the extreme traits that are being favoured by natural selection as opposed to the intermediate traits. The variance in the population increases and two species begin to emerge. Directional selection, on the other, favours one end of the extreme traits. Disruptive selection is a form of sympatric speciation.
Directional selection
A directional selection is the tendency for an extreme phenotype such as large size or extreme coloration to be favored over other phenotypes. Direct selection allows the favored or selected allele to increase as a result of differences in survival and reproduction among different phenotypes.

What events took place in anna's immune system when invaded by the s. marcescens infection? be specific in your response?
The immune system started to use its antibiotics to battle the infection. It also sent B-Cells to fight the infection while the T-cells kept that immune system strong. The immune system also inflamed the muscles to know where the antigens were so it knew where to kill them
When Anna's immune system was invaded by the s. marcescens infection, the immune system induces pro-inflammatory substance called Cytokinesis.
Explanation:
Apart from this it initiates the release of protein called as antibodies which are responsible for identification and elimination of disease causing pathogens from the body.
S. marcescens refers to gram negative bacteria which cause serious urinary as well as respiratory infections. Usually it is found in places such as hospitals, soil and water.
Which is a component of the modern cell theory that was not part of the original cell theory? All organisms are made of cells. All cells are similar in composition and metabolic activities. All cells come from preexisting cells. A cell is the basic unit of structure and function for all living things.
All organisms are made of cells. All cells are similar in composition and metabolic activities. Thus, the correct option is A.

Thermohaline circulation is movement of seawater due to differences in what two properties?
1)
density and temperature
2)
salinity and temperature
3)
temperature and depth
4)
salinity and density
Answer is 2. Salinity and temperature.
The movement of water in the ocean is called thermohaline circulation. This circulation is depends on temperature and salinity. These two factors together affect the density of seawater. More dense seawater sinks below less dense seawater and thus the oceans circulate partially based upon their temperature and salinity. Heat from the Sun affects temperature of seawater. Surface seawater gets more heat near the equator than near the poles, and similarly more in the summer than in the winter. Salinity of seawater is affected by evaporation, precipitation, ice formation, and ice melting. Evaporation increases the salinity of seawater because when seawater evaporates, the salts are left behind, thus increasing their concentration. Precipitation and river input decrease salinity because the input of freshwater dilutes the salts in seawater, thus decreasing their concentration.
