Answer: changes in climate
Change in climate information that fossils in samples from Earth's crust reveal about Earth's history. So, the correct option is (A).
What are Fossils?A fossil is defined as the preserved remains, impression, or trace of a once-living thing from a past geological age, including bones, shells, exoskeletons, fossilized traces of animals or microbes, amber, hair, petrified wood, and DNA. The totality of fossils is known as the fossil record.
There are five types of fossils which are as follows:
Body FossilsMolecular FossilsTrace FossilsCarbon FossilsPseudo fossilsThe fossil record shows that the types of living things on Earth changed over time which reveals the Earth's history.
Thus, change in climate information that fossils in samples from Earth's crust reveal about Earth's history. So, the correct option is (A).

For this cell division, you can see that 4 daughter cells are made that have half the genetic information as the original. What type of cell division is this?
a) Diffusion
b) Mitosis
c) Meiosis
d) Photosynthesis
Answer:
The cell division where 4 daughter cells with half of the genetic information of the original are obtained is meiosis (option c).
Explanation:
Meiosis is a type of cell division through which sex cells or gametes are obtained. It is a reductive division, since the daughter cells resulting from the process contain half of the chromosomal charge with respect to the original one.
In the process of meiosis, four haploid cells are obtained from a diploid cell, each of which is involved in the reproduction of the species. This mechanism of division occurs in two stages, called meiosis I and II.
The other options are not correct because:
a) Diffusion: it is a passive trans-membrane transport mechanism.
b) Mitosis: is the cellular division of somatic cells, where the result is two daughter cells identical to the original.
d) Photosynthesis: is the mechanism by which plants obtain energy and nutrients, from solar energy.

List down 5 evidence of exogenic processes and show how it affects or how it is affected by human activities.
Answer:
Mass wasting has drastic effects on human and animals life in the form of landsliding , earthquakes . Deposition is the pres in which sediments , rocks and soil are added land mass . A positive effect of deposition is that it creates new land . And negative effect is it takes away new lands .
The five (5) evidence of exogenic processes on Earth's surface include the following:
1. Weathering.
2. Stripping.
3. Erosion.
4. Mass wasting.
5. Deposition.
Exogenic processes can be defined as the processes that occur at or near the surface of planet Earth due to the action (influence) of exogenic forces or geomorphic agents.
The five (5) evidence of exogenic processes on Earth's surface include the following:
1. Weathering: the removal of various minerals from rocks causes depletion in oil and gas reserves that may be available for human consumption.
2. Stripping: it involves the removal of essential chemical elements and components from precious stones and landform such as a mountain.
3. Erosion: this causes flooding and washing away of various soil nutrients and as such affects agriculture.
4. Mass wasting: it moves rock debris, soil nutrients, and regolith downward, which are substances that are useful for certain human activities such as during mining.
5. Deposition: it is a consequence of erosion and it result in the laying down of sediment on a landform or landmass.
This sometimes make the foundation of buildings stronger to withstand stress.

The leaves of a plant absorb sunlight in order to help the plant undergo photosynthesis.
A plant with large, broad leaves would likely be able to absorb more sunlight than a plant with small, narrow leaves. The broad-leafed plant would therefore be better suited for living in an area that does not receive much sunlight.
Which plant would likely live in a shady area which only receives sunlight for a small portion of the day?
A.
none of these
B.
plant Z
C.
plant Y
D.

Which of these changes to fuel consumption would lessen human
impacts on global climate?
Select one:
A) Decreasing research of all wind or water-based electricity generation technologies
B) Switching from coal to natural gas or nuclear energy to generate electricity
C) Increasing electricity production from coal
D) Banning any form of carbon emissions trading programs
Switching from coal to natural gas or nuclear energy to generate electricity will lessen human impacts on the global climate.
What is climate change?It is the changes to climate brought about by anthropological emission of greenhouse gases.
Greenhouse gases are emitted from human actions such as the burning of coal, removal and burning of forest layers, etc.
Thus, in order to lower human impacts on climate, replacing activities such as the burning of coal with clean technology such as nuclear energy to generate electricity would go a long way.

Akshay decides one day to run a marathon without any training. After 10 minutes your lapsed and akashay, has run half a mile, he begins to get cramps in his thigh he's also breathing very rapidly what is causing the cramps on his legs?
Answer:
Lactic acid accumulation in the leg muscles
Explanation:
Muscle cramps are painful feelings caused by sudden contractions of the muscle. Cramps are caused by several reasons, however, based on the description of Akashay's activity, it is caused by ACCUMULATION OF LACTIC ACID in the leg muscles due to strenuous exercise.
According to this question, Akashay decided to run a marathon without any prior training. However, he started to get cramps on his thigh coupled with rapid breathing. There is a lack of oxygen in his cells, hence, anaerobic respiration was used leading to the formation of lactic acid. The buildup of lactic acid is what causes the painful sensation called CRAMP.

Explanation:
how does water get into the aquifer? i will mark branliest if you answer correct!
Answer:
Water gets into an aquifer from the land surface
Answer:
Water gets into an aquifer from the land surface. Typically, precipitation falling onto the Earth's surface soaks into the ground and flows down to the water table.
Explanation:
Most wells do not get their water from underground rivers, but instead get the water from aquifers. Aquifers are layers of rock and soil with water flowing through their small pores. ... New water, such as from rain or melting snow, drips down into the ground through the pores and cracks in the rocks and soil. Groundwater is transported through aquifers because of two main reasons: gravity and pressure. In unconfined aquifers, which we concentrate on because they are more likely to be contaminated, water always flows from high points to low points because of gravity.
