The local police have provided you with some missing persons reports. Look at the information for each missing person and compare it to your findings. Could the bones belong to any of these missing persons? If so, which ones, and why? Keep in mind that 1 inch = 2.54 cm. (2-3 sentences)
Answer:
That person whose height resembles the dead body.
Explanation:
The bones belong to any of these missing persons if we do analysis and compared the length of the dead bodies with the information of each missing person. If the height of the missing person resembles to the height of the dead bodies, we can send it for evaluation and confirming other information about that person such as gender or any fracture in the body. If these information are found correctly so we can conclude that this body resembles to the missing person who is separated.

What happened during the Pleistocene to cause global cooling?
low solar activity
breakup of Pangaea
fossil fuel consumption
a shift in earth’s orbit
Answer:
D) a shift in earth’s orbit
Explanation:
^^^^^^^^^
A shift in Earth's orbit caused global cooling during the Pleistocene. This period, which began around 2.6 million years ago and lasted until about 11,700 years ago, was marked by a series of glacial cycles, with ice sheets advancing and retreating across much of the Northern Hemisphere. Hence the correct option is D.
What is Global cooling?Global cooling refers to a long-term trend of decreasing temperatures across the Earth's surface and atmosphere over an extended period of time. This can lead to changes in climate patterns, including changes in precipitation, sea levels, and weather events.
Global cooling can occur due to a variety of factors, such as changes in solar radiation, volcanic activity, or shifts in the Earth's orbit. In recent decades, global warming has been the predominant trend, with temperatures rising due to human activities such as the burning of fossil fuels and deforestation.
The cooling is thought to have been caused by changes in Earth's orbit, including changes in the tilt and orientation of its axis, as well as variations in its elliptical path around the sun. These changes affected the distribution of sunlight and solar radiation across the planet, leading to cooler temperatures and the growth of ice sheets.

a.those that can change themselves to fit their environment
c.those that produces the fewest offspring
b.those that are the largest and produce the most offspring
d.those that have the variation best suited to their environment
Answer:
D
Explanation:
Darwin believed that the species with the best variation to their environment had the biggest chance at surviving.
Darwin believed that the species with the best variation to their environment had the biggest chance at surviving.
What is Natural selection?
The process by which species adjust to their habitats is known as natural selection. It is the force behind evolution.
The process through which populations of living things adapt and change is known as natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways.
This variety indicates that some people have characteristics that are more environment-appropriate than others. People that possess advantageous qualities, or adapted traits, are more likely to live and procreate.
Therefore, Darwin believed that the species with the best variation to their environment had the biggest chance at surviving.

Explanation:
The term eutrophication refers to the enrichment of surface water with nutrients. This process is related to human pollution activities.
Eutrophication is the biological process that generates in water by an oversupply of nutrients or organic matter. This matter, mainly compounded with nitrogen or phosphorous, favors the phytoplankton multiplication (microscopic plants growing on the water surface) and other aquatic plants. This overgrowth leads to an enhance in primary productivity. Nitrogenated compounds might come from human and animal wastes, while phosphorated compounds might come from fertilizers and other chemicals used in agriculture, that penetrates the soil and reaches water bodies.
Little by little begin sedimentation is caused by the death of some vegetable organisms that sink in the bottom. These sediments rich in organic matter suffer decomposition in the presence of oxygen.
When oxygen disappears, anaerobic bacteria act and produce fermentation.
On the surface, plants and phytoplankton keep growing, creating a mantle that impedes the light reach deeper areas. The phytoplankton overgrowth on the water surface and the fermentation processes in the bottom originate toxic compounds that damage the animals. Animals die, creating more sediments in the bottom where there are anaerobic conditions.
Decomposition and fermentation processes increase, producing a bad smell.
The result of eutrophication is the stratification of the water mass:
• First superficial layer, the overgrowth of blue-green algae, produces toxins and interrupts the pass of light to deeper areas. The surface then becomes warmer.
• The second layer might have oxygen available for the animals.
• In the third layer, there is no oxygen, so life is impossible for animals or plants.
• In the fourth layer, there are animals and plant remains in the process of sedimentation.
• At the bottom, there are organic matter and anaerobic bacteria in charge of decomposition and fermentation, through which they produce toxic gases and smell.

the price of a book is thrice that of an exercise book. of a student spend #9600 on book and #8000 on exercise book, he has 56 items altogether:
(a) what is the price of an exercise book?
(b) what is the difference between the price of a book and an exercise book?
Answer:
a) price of an exercise book = #200
b) #400
Explanation:
Let x represent the price of the book
Let y represent the price of the exercise book
- According to this question, the price of the book is thrice that of an exercise book i.e. x = 3y
- Also, the question states that if a student spend #9600 on book and #8000 on exercise book, he has 56 items altogether. This means that to get how many books and exercise books he bought, we divide the price of book and exercise book he bought by the price of each book (x) and exercise book (y) respectively. Mathematically, this means:
- Student bought 9600/x books
- Student bought 8000/y exercise books
So, 9600/x books + 8000/y exercise books = 56 item
9600/x + 8000/y = 56
Since x = 3y
We can say;
9600/3y + 8000/y = 56
Find the L.C.M of 3y and y = 3y and solve using fraction method (see attachment).
9600 + 24000/3y = 56
33600/3y = 56
Cross multiply
33600 = 56 × 3y
33600 = 168y
Divide both sides by 168
33600/168 = 168y/168
200 = y
y = 200
Since, x = 3y
x = 3 × 200
x = 600
Therefore, the price of book (x) and exercise book (y) are #600 and #200 respectively.
b) The difference between the price of a book and an exercise book i.e. x - y
= #600 - #200
= #400
