Oligogenic traits are those that have a discrete distribution and whose expression is driven by a few genes with enormous impact.
What are genes ?A gene is the most fundamental physical and functional element of heredity. DNA is the building block of genes. Some genes serve as blueprints for the creation of proteins. Many genes, however, do not code for proteins. Genes in humans range in size from a few hundred DNA bases to over 2 million bases. The Human Genome Project, an international research effort that aimed to discover the sequence of the human genome and identify the genes that it contained, concluded that humans have between 20,000 and 25,000 genes.
Every individual has two copies of each gene, one from each parent. The majority of genes are the same in all persons, although a small number of genes (less than 1% of the total) deviate somewhat.
What is DNA ?Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries genetic information for the development and functioning of an organism. DNA is made of two linked strands that wind around each other to resemble a twisted ladder — a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases: adenine (A), cytosine (C), guanine (G) or thymine (T). The two strands are connected by chemical bonds between the bases: adenine bonds with thymine, and cytosine bonds with guanine. The sequence of the bases along DNA’s backbone encodes biological information, such as the instructions for making a protein or RNA molecule.

Would it make a difference if the photographer of
this image intended to hang it in a gallery as "art?"
What if the goal of the artist was to make viewers
mad or uncomfortable? What if the artist created
this image as a way to engage viewers in
critiquing both Native American and non-Native
American cultures?
Answer:
The intentions of the photographer or artist may influence how viewers interpret the image and the context in which it is presented. If the photographer intended to hang the image in a gallery as "art," this could signal to viewers that the image is intended to be viewed in a particular way, and may prompt viewers to consider the image's artistic or aesthetic qualities.
If the goal of the artist was to make viewers mad or uncomfortable, this could influence the viewer's emotional response to the image and potentially prompt them to think more critically about the issues raised by the image.
Similarly, if the artist created the image as a way to engage viewers in critiquing both Native American and non-Native American cultures, this could prompt viewers to consider the image in the context of broader cultural and political issues, and may encourage them to think more critically about the ways in which different cultures are represented and understood.
In short, the intentions of the photographer or artist can play a significant role in how viewers interpret and respond to an image, and can shape the context in which the image is viewed and understood.

What was the climate like prior to the extinction ?
Answer:
The extinction you are referring to is unclear, as there have been several mass extinctions throughout Earth's history. However, it is generally accepted that climate has played a significant role in many of these events. Prior to some of the mass extinctions, such as the Permian-Triassic extinction and the Cretaceous-Paleogene extinction, the climate was warm and tropical with high levels of carbon dioxide in the atmosphere. This warm climate was likely a contributing factor to the extinction, as it may have led to changes in sea level, ocean circulation, and weather patterns that disrupted ecosystems and caused widespread extinction of species. However, it is important to note that climate is just one of many factors that can contribute to mass extinction events, and there are often multiple causes involved.

Answer:
Natural selection is a theory originally popularized by Charles Darwin. According to this theory, animals in the natural environment change over time as beneficial traits are preserved, and traits which do not advance the species are slowly weeded out. Natural selection, a concept first theorized by Charles Darwin, is the adjustment of genes throughout generations based on factors that help it survive. Sometimes this is survival of the fittest or the organisms that are better suited to the environment in other ways.

D. 10 times less acidic than tomato juice.
Based on the pH scale, Milk has a pH of 6 while Tomato juice has a pH of 4, milk is 100 times less acidic than tomato juice.
The correct answer is B.
What is pH?The pH scale is logarithmic, meaning that each number on the scale represents a tenfold difference in acidity or basicity.
A pH of 4 is 10 times more acidic than a pH of 5, and 100 times more acidic than a pH of 6. Therefore, to compare the acidity of milk (pH 6) and tomato juice (pH 4), we can say:

Theoretical frame:
Hardness is one of the physical properties of minerals and is a significant one when identifying and recognizing them.
Hardness measures the resistance level of a surface to abrasion. In the specific case of minerals, it measures how minerals resist being scratched or penetrated.
The hardness level is determined by an attempt to scratch or produce a mark on an unmarked surface using sharp elements, such as nails, copper coin, glass, or a steal knife. Notice that these elements also vary in their hardness.
There are different methods used to define hardness, and they are not comparable to each other. The Mohs hardness method defines an ordinary qualitative scale that characterizes the mineral according to their resistance to being scratched by a harder element.
According to the Mohs hardness scale, the level in which the given minerals are placed is as follows,

sort the following items according to whether they are reactants or products in the anaerobic reduction of pyruvate during lactic acid fermentation. Drag each item to the appropriate bin.
A. NAD+
B. NADH+
C. lactate
D. pyruvate
1. reactants
2. products
In the anaerobic reduction of pyruvate during lactic acid fermentation, the reactants will be NADH and pyruvate and the products will be NAD+ and lactate.
Anaerobic reduction is the conversion of pyruvate into lactate in the absence of oxygen. Thus reaction occurs in the anaerobic organisms as well as in the muscles oh humans during intense exercise. For this to happen, the NAD+ is reduced to NADH.
Pyruvate is the product formed due to the breakdown of glucose in the reaction glycolysis. It is a 10 step process that requires ATP as well as yields some ATP. The net gain of ATP in the reaction is of 2. The process can occur in both aerobic and anaerobic organisms.

If the half life of an element was 430 years and you had 2000 atoms of this element, how long would it take to undergo complete radioactive decay? What year would it be when the element finished decaying?
part a.
it would take an estimated 2984 years for the element to undergo complete radioactive decay.
How do we calculate?N = N₀ * (1/2)\(^(^t ^/^ T^)\)
N = final number of atoms remaining
N₀ = initial number of atoms
T = half-life of the element
0 = 2000 * (1/2)^(t / 430)
(1/2)^(t / 430) = 0
log₂((1/2)= log₂(0)
(t / 430) * log₂(1/2) = log₂(0)
0.01 = (1/2)^(t / 430)
log₂(0.01) = (t / 430) * log₂(1/2)

Subthreshold summation happens when two or more presynaptic inputs that are sub-threshold (i.e., they cannot create an action potential) combine their effects on the postsynaptic neuron.
Here, the postsynaptic neuron has an RMP of -70mV and a typical threshold of -55mV. When neuron X is stimulated, it depolarizes by 0.5 mV.
When X and Y are stimulated simultaneously, the postsynaptic neuron depolarizes by 1 mV, which is sub-threshold (below -55mV).
