If intelligence is so useful, why do so few species have it?
Explanation:
Could intelligence simply be unlikely to evolve? Unfortunately, we can’t study extraterrestrial life to answer this question. But we can study some 4.5 billion years of Earth’s history, looking at where evolution repeats itself, or doesn’t.

Once an experiment is complete,
which of the following is NOT a step to
be taken with the data?
A. incrpreting it
B. plotting it on a graph to find correlations
C. analyzing it with statistical analysis
D. altering it to fit within the hypothesis
Answer:
D. altering it to fit within the hypothesis
Explanation:
An experiment is carried out to fill an inquisition i.e. to answer a question. According to the scientific method, prior to experimentation, there must be a HYPOTHESIS. The hypothesis is tested for rejection or approval via experimentation.
After the experiment has been conducted, several things can be done with the data obtained. For example:
- Data can be interpreted
- the data can be plotted in a graph to find correlations
- It can be analyzed it with statistical analysis.
One thing that should never be done is; altering the data from experimentation to fit in the hypothesis.
What conditions need to be present for an atom to form hydrogen bonds?
For an atom to form hydrogen bonds, it needs to be bonded to a highly electronegative atom (such as nitrogen, oxygen, or fluorine) and have a hydrogen atom attached to it.
Hydrogen bonds are intermolecular forces that occur between a hydrogen atom bonded to a highly electronegative atom and another electronegative atom nearby. The highly electronegative atom, often nitrogen (N), oxygen (O), or fluorine (F), attracts the shared electrons in the covalent bond towards itself, creating a partial negative charge. This leaves the hydrogen atom with a partial positive charge.
The conditions necessary for hydrogen bonding to occur are:
Presence of a Hydrogen Atom: There must be a hydrogen atom (H) bonded to an electronegative atom (N, O, or F) in the molecule or adjacent molecules.Highly Electronegative Atom: The electronegative atom (N, O, or F) must have a strong attraction for electrons, creating a significant partial negative charge.Close Proximity: The electronegative atom with the partial negative charge must be close enough to another electronegative atom in another molecule or nearby region to allow for electrostatic attraction.These conditions are essential for the formation of hydrogen bonds. The hydrogen bond itself is a relatively weak force compared to covalent or ionic bonds, but it is significant in biological systems and plays a crucial role in many biological processes. Hydrogen bonding contributes to the unique properties of water, the stability of protein structures, the binding of DNA strands, and various other molecular interactions.
In summary, for an atom to form hydrogen bonds, it must be bonded to a highly electronegative atom (N, O, or F) and have a hydrogen atom attached to it, with another electronegative atom in close proximity to allow for the formation of electrostatic interactions.

What changes can occur in an aquatic ecosystem as a result of nutrient loading? (Site 1)
Answer/Explanation:
Essential nutrients such as nitrogen, phosphorus, at specific moderate level are needed for the overall functionality of the aquatic ecosystem. However, when excess of these elements infiltrates the aquatic ecosystem, the nutrient overload causes a surge in the growth of aquatic plant. For example, algal bloom. These increased growth of aquatic plant further takes up space and oxygen, prevents sunlight and later leads to what is known as "dead zone". It is a condition of an ecosystem having little or no biological activity. Aquatic life is impacted negatively when this occurs.
These are the changes that occurs as a result of nutrient loading.

Appropriate Question:-
The output for a 60kg woman who runs up a 3m high flight of stairs in 3.5 sec.starting from rest but having a final speed of 2 m/s.
Given:-
Mass of woman=m=60kg.
Height=h=3m
Time=t=3.5secs.
To find :-
Here we want to calculate the output for a woman
Here first we should calculate work done first.
work \: done = mghworkdone=mgh
Applying the values,
work \: done = 10 \times 60 \times 3workdone=10×60×3
Work done= 1800Joule.
Now , lets calculate power,
power = \frac{workdone}{time \: taken} power=
timetaken
workdone
Now,
Applying the values ,
power = \frac{1800}{3.5} power=
3.5
1800

A geologist finds some tilted sedimentary rock layers.
Which conclusion can the geologist draw by looking at the rock layers?
1.Their absolute age is 600 million years.
2.They were tilted before they were deposited.
3.They were originally deposited horizontally.
4.The youngest layer was originally deposited as the bottom layer.
Answer:
Angular unconformity also causes geologic tilting. Angular unconformity occurs when parallel strata of sedimentary rocks are deposited on layers that are tilted, perhaps as a result of erosion. So the answer I think is B/2.

How does the natural process of meiosis support evolution?
A. Each daughter cell mutates its own DNA during Reduction Division to produce more variation.
B. Each daughter cell is unique, providing natural variation.
C. Each daughter cell is identical, providing natural variation.
D. It does not support evolution.
During meiosis, each daughter cell tends to undergo mutation of its own DNA and leads to more variation. The correct option is A.
What is meiosis?Meiosis is a sort of cell division that occurs in organisms which reproduce the fusion of gametes and results in a diminution in the number of chromosomes in gametes. Body cells in humans are diploid, with two sets of chromosomes.
Meiosis is a process of cell division that produces 4 gamete cells while reducing the number of chromosomes in the parent cell by half.
This process is essential for the generation of egg and sperm cells for reproduction.
Meiosis reduces the number of chromosomes in a cell by half while also generating new allele pairings that are dispersed across daughter cells via segregation and recombination.
This genetic reshuffling, which is thought to be the basis of reproduction success, reduces genetic affiliations within and between loci.
Thus, the correct option is A.

The displacement of the object is 303.75m.
What is displacement?Distance covered by a body in a particular direction is called displacement. To calculate displacement from a velocity-time graph, we calculate the area under the curve.
The displacement is covered by drawing perpendiculars on the time axis. Let AB be the first and CD be the second perpendicular.
Extend A to CD at E.
Now, area of ABCD trapezium
= (AB + DC)/ 2 × AD
= (10.5 + 30)/2 m/s × 15 s
= 303.75 m is the area under the curve.
Therefore, 303.75 m is the displacement of the object.

What is oxygen ?
Oxygen is the chemical element with the symbol O and atomic number It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. Oxygen is Earth's most abundant element, and after hydrogen and helium, it is the third-most abundant element in the universe. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula O
Diatomic oxygen gas currently constitutes 20.95% of the Earth's atmosphere, though this has changed considerably over long periods of time. Oxygen makes up almost half of the Earth's crust in the form of oxides.
Many major classes of organic molecules in living organisms contain oxygen atoms, such as proteins, nucleic acids, carbohydrates, and fats, as do the major constituent inorganic compounds of animal shells, teeth, and bone. Most of the mass of living organisms is oxygen as a component of water, the major constituent of lifeforms. Oxygen is continuously replenished in Earth's atmosphere by photosynthesis, which uses the energy of sunlight to produce oxygen from water and carbon dioxide. Oxygen is too chemically reactive to remain a free element in air without being continuously replenished by the photosynthetic action of living organisms.
