Answer:
C. Downward social drift hypothesis
Explanation:
In the scenario, being described Leon's story lends credibility to Downward social drift hypothesis. This hypothesis states that there is a clear relationship between mental illness and social class, in which the illness leads the individual to have a downward shift in social class. This is the case with Leon, since he was an upper-class individual until he developed schizophrenia, which ultimately caused him to drop lower and lower in social classes. All the way down to homeless.

In an organism, X, it is found to be impossible to generate loss-of-function mutants for most genes. There is an alternative method of introducing random mutations that can later be screened for the gene(s) in question. This can be accomplished by using insertions due to what genetic entities?
Answer:
Transposable elements (TE)
Explanation:
A transposon, also known as 'jumping genes', is a particular sequence of DNA that can relocate inside of the genome. It affects the genetic identity and can be made use of to either reverse a mutation or create one - it duplicates that genetic sequence. Retrotransposons is a class of TE found in viruses.

Predict what would happen if we had no system of lymphatic vessels, and tissue fluid was moved directly back into the circulatory system throughout the body.
Answer:
If there was no system of lymphatic vessels, there would be no drainage of excess fluid from the tissues and the lymphatic fluid would accumulate in the tissues, causing them to swell.
Explanation:
The lymphatic vessel is made up of tiny vessels that are closed at one end and can be found in the spaces in the cells, except the central nervous system and the non-vascular tissues.
The main function of the lymphatic vessel is to move lymph which is a fluid that contains infection-fighting white blood cells to every part of the body.
So, if there was no system of lymphatic vessels, and tissue fluid was moved directly back into the circulatory system throughout the body. the lymphatic fluid would accumulate in the tissues, causing them to swell.

The frequency of spear grasses in different locations of an abandoned field is 40 After throwing a quadrant 80 times. Calculate its population size using a quadrant dimension of 1 square meter.
Answer:
40
Explanation:
The population size refers to the total number of individuals in a population. It can be obtained by counting the total number of individuals in a population. In a typical plant field where it is almost impossible to count the number of individuals, the population size can be mathematically estimated using the quadrat method:
Population size = (A/a) x n,
where A = area of the field, a = area of quadrat, and n = number of plants per quadrat.
In the illustration, the area of the abandoned field was not given. Hence, it is assumed that the area of the field is equivalent to the number of quadrat thrown. Since the size of the quadrat is 1 square meter:
Area of the field = 80 x 1 = 80 square meters.
Number of plant per quadrat = 40/80 = 0.5
Population size = 80/1 x 0.5 = 40
Therefore, the population size is 40 spear grasses.

Instructions on how to control your cells are contained in what part of the DNA?
Answer:
Genes
Explanation:
The genes are specific fragments of the DNA molecule that contain the information necessary to synthesize different types of RNAs, including messenger RNAs (mRNAs) which are subsequently translated into proteins required for different cellular functions including replication, cell cycle, proliferation, apoptosis, etc. Genes are first transcribed to RNA during transcription. In eukaryotic organisms, the genes contain both exonic and intronic sequences that are jointly transcribed into the primary mRNA, and then the introns are removed during RNA splicing. The genes have a specific initiation signal sequence known as start codon (AUG) and termination codons (UGA, UAA, UAG) that terminates the translation of the mRNA.

PLEASE ANSWERR
Answer:
a) i) Xylem
ii) Upper epidermis
iii) Stoma
iv) Chroloplast
v) Palisade cell layer
b) By a waxy layer on the cuticle of the leaf
Explanation:
The plant's leaves have a large surface area that is capable of absorbing sunlight. The plant's waxy layer in the surface of the leaf protects it from the loss of water, as well as of diseases caused by the entry of microorganisms. The palisade cell's surface is a single layer of cells underneath the upper epidermis that is adapted to absorb light energy.
The waxy layer is a primary physical barrier composed of insoluble polymers and lipids whose function is to protect the leaves against the entry of harmful organisms including virus, bacteria and fungus. Moreover, the plant's waxy cuticle is also a barrier that prevents the loss of water and solutes.

Describe under what conditions you might expect your cells to undergo anaerobic respiration. Be specific as to why these conditions would prevent normal cellular respiration to proceed. What product is produced under anaerobic conditions and is it harmful?
Answer:
Explanation:
Cells start undergoing anaerobic respiration when energy requirement is high and there is not sufficient availability of oxygen to produce required energy .
For example , when we we run fast , energy requirement by muscle cell is high but available oxygen level is not sufficient so cells start anaerobic respiration which produces lactic acid and this product creates tire-ness.
For normal respiration , oxygen is required . If there is lack of oxygen , aerobic respiration is not possible .
In yeast cells , alcohol is produced by anaerobic respiration. Alcohol is not harmful . In muscle cells , lactic acid is produced which is harmful .

One primary advantage of light microscopy over electron microscopy is that ________. light microscopy provides higher contrast than electron microscopy light microscopy provides for higher magnification than electron microscopy light microscopy allows the visualization of dynamic processes in living cells light microscopy provides for higher resolution than electron microscopy
Answer:
light microscopy allows the visualization of dynamic processes in living cells light
Explanation:
Light microscopy has a biggest advantage over electron microscopy because it all the visualisation or ability to observe living cells and biological activity such as the uptake of food, cell division and movement. Light microscopy can be use in-vivo staining techniques to visualise the uptake of colored pigments by the cells which cannot be observed with electron microscopy because in electron microscopy the element must be fixed, dehydrated or dead before been visualised . Electron microscope cannot observe living cells and can only observe dead or dry specimens so that electrons can pass through the specimen to be able to observe.
Light microscope has higher penetrating power than electron microscopy thus allows the visualization of dynamic processes in living cells. Therefore, option c is correct.
Microscopy is the technical field of using microscopes to view samples & objects that cannot be seen with the unaided eye.
Light microscopes can also be used to visualize dynamic processes in living cells because it has greater penetrating power than electron. Electron microscopes uses high-energy electrons that would damage the cells.
Electrons have shorter wavelength than visible light, so provide higher resolution than light microscopes.
Electrons have much a shorter wavelength than visible light, and this allows electron microscopes to produce higher-resolution images than standard light microscopes.
Therefore, option c is correct that light microscopy allows the visualization of dynamic processes in living cells.

A researcher interested in the disappearance of fallen leaves in a deciduous forest carried out a field experiment that lasted nearly a year. She collected all the leaves from 100 plots scattered throughout the forest. She measured the amount of leaves present in November, May and August. The percentages reflect the number of leaves found, using the November values as 100 percent.
Answer:
Elm: 50 %; 1 %
Hazel: 69 %; 4 %
Explanation:
Assume the table looked like this.
[tex]\begin{array}{crrr}\textbf{Month} & \textbf{Ash} & \textbf{Elm} &\textbf{Hazel}\\\text{Nov} &\text{4271 g}& \text{3481 g} & \text{1723 g}\\ & 100\, \% & 100\, \%&100\, \%\\\text{May} & \text{2431 g} & \text{1739 g} & \text{501 g}\\& 100\, \% & x \, \% &z \, \%\\ \text{Aug} & \text{1376 g} &\text{35 g} & \text{62 g}\\& 100\, \% & y \, \% & w \, \%\\\end{array}[/tex]
To get the percentages for each species for May and August, you divide that month's mass by the November mass and multiply by 100.
[tex]x = \dfrac{\text{1739 g}}{\text{3481 g}} \times 100 \, \% =50 \,\%\\\\y = \dfrac{\text{35 g}}{\text{3481 g}} \times 100 \, \% = 1 \,\%\\\\z = \dfrac{\text{501 g}}{\text{1723 g}} \times 100 \, \% = 69 \,\%\\\\w = \dfrac{\text{62 g}}{\text{1723 g}} \times 100 \, \% = 4 \,\%\\\\[/tex]

The Black Death was a pandemic spreading across Europe between 1348 and 1350. Estimates states that 30% to 60% of Europe's population died from the Black Death. If we look at Europe's population before the pandemic and compare it to the population several generations later, what are we likely to find?
A. More genetic diversity in later generations.
B. Less genetic diversity in later generations.
C. Less genetic diversity in earlier generations.
D. The same degree of genetic diversity in later as in earlier generations.
Answer:
The correct answer is option B, that is, less genetic diversity in later generations.
Explanation:
A pandemic that spread across Europe between 1348 and 1350 was named as the Black Death. It has been predicted that of the total population of Europe at that time 30 to 60 percent died due to the pandemic. The geneticists are still trying to document the influence of Black Death on the population of Europe today.
It has been found that in England, the genetic diversity is found much lower in comparison to what it was in the eleventh century, and is primarily due to so many people dying in the 1300s. However, the rest of Europe does not demonstrate a dropped amount of genetic variation, which maybe because of the enhanced patterns of migration in other places.
