Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.
Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as much as 29 kilometers (18 miles) wide, and 1,600 meters (1 mile) deep.
Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time. The length of exposure often contributes to how vulnerable a rock is to weathering. Rocks, such as lavas, that are quickly buried beneath other rocks are less vulnerable to weathering and erosion than rocks that are exposed to agents such as wind and water.
For example, certain kinds of air pollution increase the rate of weathering. Burning coal, natural gas, and petroleum releases chemicals such as nitrogen oxide and sulfur dioxide into the atmosphere. When these chemicals combine with sunlight and moisture, they change into acids. They then fall back to Earth as acid rain.

Which statement about human population growth is FALSE?
Choose: c) The global population is expected to peak at 7 billion, then begin decreasing.
The false statement is: The global population is expected to peak at 7 billion, then begin decreasing.
What is meant by population growth?
Population growth is the increase in the number of humans on Earth. For most of human history, our population size was relatively stable. But with innovation and industrialization, energy, food, water, and medical care became more available and reliable.
Was there population growth in 2020?Population gains attributable to natural increase rose as high as 1.1 million in 2016-17, but dropped to 677,000 in 2019-20 and then again to 148,000 in 2020-21.

Most chemical reactions within cells do not occur spontaneously. Instead, they need a catalyst to get them started. Why do you think this is so?
Answer:
A catalyst is a chemical involved in, but not changed by, a chemical reaction. Many enzymes function by lowering the activation energy of reactions. By bringing the reactants closer together, chemical bonds may be weakened and reactions will proceed faster than without the catalyst.

A hypothesis is a plausible explanation for a particular fact, observation, or process. Write a hypothesis about how the various concentrations of acid will affect the amount of limestone that is dissolved from each jar.
The hypothesis will state as follows: IF the concentration of acid increases, THEN, the amount of limestone dissolved will also increase.
WHAT IS A HYPOTHESIS?
A hypothesis is a crucial part of the scientific method. It is a testable explanation of an observation or a proposed answer to a scientific question. A hypothesis, which must be testable via experimentation, can either be accepted or rejected depending on the outcome of the experiment. A hypothesis is an IF, THEN statement that must include the independent and dependent variables of the experiment i.e. it must show how the dependent variable (effect) is affected by the independent variable (cause).In this case regarding the dissolution of limestone with respect to different concentrations of acid, a possible hypothesis will state as follows:
"IF the concentration of acid increases, THEN, the amount of limestone dissolved will also increase".

energy capture
A. where light energy is not available.
B. in oxygen-rich environments.
C. when water has a pH of 7.
Answer: the answer would be a
Explanation: because I had the same question too on acellus and got a right
Photosynthesis makes use of light energy while chemosynthesis is the main source of energy capture where light energy is not available.
What is photosynthesis?It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

Explanation:
Ricky has been struggling to sleep due to the loud noise of police sirens at night, but has noticed that the sirens have been disturbing his sleep less as he gets used to the noise. Ricky is experiencing habituation.
What is habituation?habituation is a type of response where complete elimination of a particular response or zero frequency of occurrence occur.
If the stimulus continues for an additional number of trials, although no changes occur but the response will exhibit lower levels of recovery.
Habituation is a non-associative learning in which an automatic decrease in the intensity of a response occur which is repetitive, weak stimulus, without serious consequences, for example, ignoring stimuli
Habituation defines as the fading of the response over the course of monotonous stimulation, and sensitization refers to processes of increased response.

What does science tell us
Carbohydrates stored in the liver are in the form of starch.
True
False
Answer:
It is false. carbohydrates are stored in form of glycogen.
When glycogen is formed from monosaccharides, it occurs by a process called hydrolysis.
True
False
Answer:
yes its true. it occurs by a process called hydrolysis
The formation of glycogen from monosaccharides happens through the process of dehydration. So the statement is false.
What is the process of glycogen formation?
The process of formation of glycogen is called glycogenesis. Glycogen is the storage form of glucose, a primary carbohydrate in the liver and the muscle cells of animals
The process of Glycogenesis happens when the levels of glucose in the blood are high enough to allow the excess glucose to be stored.
The process of glycogenesis is stimulated by the insulin hormone. It helps the muscle cells to uptake glucose into themselves. Insulin is not required for the transport of glucose into the liver cells.
However, insulin has very important effects on the metabolism of glucose inside the liver cells. Insulates stimulates the process of glycogenesis and inhibit the process of glycogenolysis, which is the breakdown of glycogen into glucose.
Therefore the statement is false.

Which of the following statements about eukaryotic RNA is true?
O -A small cap of extra nucleotides is added to both ends of the RNA.
O -The modified RNA molecule is transported into the nucleus.
-Exons are spliced together.
-Introns are not transcribed from DNA to RNA.
Answer:
A small cap of extra nucleotides is added to both ends of the RNA
Hope you like it
Thank you ❤️
The statement 'exons are spliced together' is TRUE. The exons are the coding regions of genes.
RNA splicing is a eukaryotic mechanism by which non-coding sequences of genes called 'introns' are removed from the precursor messenger RNA (pre-mRNA), whereas protein-coding sequences called 'exons' are spliced together.These gene coding sequences (exons) are spliced together by a macromolecular complex known as the spliceosome.In consequence, a pre-mRNA is converted into a mature mRNA, which is subsequently used for protein synthesis.In conclusion, the statement 'exons are spliced together' is TRUE.
