A.weathering
B. Erosion
C. Deposition
Answer:
A. Weathering
Explanation:
Water expands when it freezes, which can cause the rocks to break apart. This is known as ice wedging and is a form of mechanical weathering. The expanding ice forces apart the pieces of the rock, causing them to crack and break. This process is especially effective in rocks with many cracks and crevices, such as limestone or sandstone.

2.It is not a fossil, because only whole organisms are fossils.
3.It is a fossil only if Hiroto finds actual parts of the organism in rocks nearby.
4.It is a fossil because footprints of organisms from million of years ago are considered to be fossils.
PLEASE HELP
Answer:
4. It is a fossil because footprints of organisms from million of years ago are considered to be fossils.
Explanation:
A geologic column can be defined as a collection of rock layers that are typically grouped based on their relative ages in a descending order i.e from oldest to the youngest.
Generally, the layers of the rock that are found in various parts of the world are known to be different because they all comprises of distinct Earth's geological history.
In this scenario, while exploring a rock formation, Hiroto finds a rock that has footprints pressed into it. A geologist tells Hiroto that the rock is millions of years old. Therefore, the claim about Hiroto’s finding that is correct is; it is a fossil because footprints of organisms from million of years ago are considered to be fossils.
A fossil can be defined as the mineral impression or remains of living organisms such as plants and animals that are prehistoric in nature.
Answer: 4) It is a fossil because footprints of organisms from million of years ago are considered to be fossils.

The one issue that the Pacific coastline is facing due to climate change is referred to as the rising sea level.
What is Climate change?This is referred to as the long-term shifts in temperatures and weather patterns and is usually caused by human activities such as the burning of fossil fuels. The burnt fossil fuel results in the production of gases which have a high tendency to trap heat.
This affects water bodies such as Pacific coastline due to the melting of continental ice sheets and the expansion of sea water thereby leading to an increase in the sea level.
There is an increase in temperature also which threatens to drown low-lying islands within the area and is therefore the reason why climate change is an important topic in today's world.

if the ecosystem is a closed system do you think the total amount of matter in an ecosystem changes?
Any ecosystem is an example that describes the open ecosystem, if the ecosystem is a closed system, it exchanges energy but does not matter.
What happens to matter in the closed ecosystem?Based on the movement of total matter into or outside the entire system, ecosystems can be divided into two general categories: open and closed. Closed systems exchange only energy, not matter, and are incredibly self-contained.
Physical and chemical changes can cause matter to change into different forms, but no matter what happens, the matter is always conserved.
Therefore, there is no creation or destruction of matter; the amount of matter is the same before and after the change.

Police arrive on the scene of a suspicious death at 11:00 am. When the medical examiner arrives, he takes the rectal temperature of the corpse and finds that it is 89.4° F. Using the Glastier equation, calculate the approximate time of death.
Using the Glastier equation, the approximate time of death of the victim is 4:53 am.
Glastier equationThe Glaister equation is a method for estimating the time of death based on the body's core temperature.
It states that the body temperature drops at a rate of about 1.5 degrees Fahrenheit per hour after death, until it reaches the ambient temperature.
To use the Glaister equation, we can subtract the rectal temperature of the body from the normal core body temperature of 98.6°F (37°C) and divide the result by 1.5°F per hour to estimate the number of hours since death.
In this case, the rectal temperature of the body is 89.4°F, so we can calculate the time of death as follows:
Time since death = (98.6°F - 89.4°F) / 1.5°F per hour
Time since death = 6.07 hours
Therefore, based on the Glaister equation, the approximate time of death would be around 4:53 am.

which is not true about the first 22 pairs of chromosomes in a karyotype
they determine the gender of the individual
each pair has one chromosome from the father and one from the mother
they are called autosomes
they are homologous meaning each pair has the same size shape, and collection of genes
Answer:
The correct answer is - they determine the gender of the individual.
Explanation:
Autosomes are the chromosomes that are numbered or non-sex chromosomes. In humans, there are 22 pairs of autosomes that are numbered from 1 to 22. These chromosomes regulate or control the pattern of inheritance of every characteristic or trait of an organism other than present on the sex chromosomes.
These are homologous chromosomes which means each pair has the same genes and has a similar shape. The gender of an individual depends on the sex chromosome only.
