Which procedure will determine if water temperature affects the weathering of sedimentary rocks?
A. Test 3 identical sedimentary rocks, 1 each in 3 different water temperatures.
B. Test 3 identical sedimentary rocks in 1 water temperature.
C. Test 1 crushed sedimentary rock and 1 whole sedimentary rock in water.
D. Test 3 identical sedimentary rocks, 1 each in acid, 1 in a base, and 1 in water.
Answer:
The correct option is A
Explanation:
To determine if water temperature has an effect on weathering of sedimentary rocks, different number (perhaps three) of identical sedimentary rocks should be obtained and then individually placed in different water temperatures (with at least one of the "water volumes" used for each having a temperature close to the room temperature so as to be used as the control).
Thus, each of the identical sedimentary rock can be broken into three and placed individually; as in one part of the rock in 20 °C of water (control), another part of the rock in 40 °C and another in 60 °C of water.
This above procedure should be repeated for the remaining two other identical sedimentary rock to confirm if there is any effect.

Answer:
There is 8 choromatids
There are 8 chromatids and 16 chromosomes.
Relation between chromosome and chromatids:A chromosome is made up two Identical Sister Chromatids. And each sister chromatids are joined at the centromere
A chromatid is one of two identical halves of a replicated chromosome. Following DNA replication, the chromosome consists of two identical structures called sister chromatids, which are joined at the centromere.Each chromosome consists of 2 sister chromatids.Before replication, one chromosome is composed of one DNA molecule.

It is unethical for a doctor to _____.
release patient information without consent
use genetic testing to diagnose genetic disorders
release patient information with the consent
treat patients with genetic disorders
Answer: release patient information without consent
Explanation:
The information obtained from patient during the process of diagnosis should be kept under confidentiality between the hospital staff or doctor and the patient. The information can be disclosed without patient's consent in two conditions- if the disclosure is necessarily required by law or in case of public interest. Except these two conditions if the information is disclosed without the patient's then the practice will be considered as unethical.

Most enzymes are proteins. Many cells make and use an enzyme called catalase to facilitate the decomposition of hydrogen peroxide (H2O2). The products of the decomposition are hydrogen (H2) and oxygen (O2). Stephanie is investigating the structure and function of catalase, and she is comparing catalase to other proteins. What can Stephanie predict will distinguish the structure of catalase from the structures of the other proteins she is studying? A. many regions made entirely of hydrogen and oxygen B. the chemical properties of the peptide bonds C. the types of amino acids it contains D. the sequence of amino acids it contains
Answer:
The correct answer is - B. the chemical properties of the peptide bonds.
Explanation:
The difference between the structures of catalase from other proteins depends on the chemical properties of the peptide bonds present in between the amino acids which decide the pH and temperature by their disruption. These bonds present between two alpha-amino acids when carboxyl of one amino acid interacts with the amino group of the other to form an amide-type covalent bond.

On any given day, the weather forecast might say that rain, snow, and sleet are expected. Which of the following statements is describing this area’s climate?
Group of answer choices
A. Last January it snowed for 17 days in a row.
B. Sleet is a combination of rain and snow.
C. The rain turned to sleet and snow later that afternoon.
D. Rain, snow and sleet are common during the month of December.
Answer:
C
Explanation:
Because it makes more sence
Frozen raindrops that hit the earth's surface are known as sleet (Ice Pellets). When sleet first forms, snow will be the precipitation that falls upwards. Thus, option C is correct.
What weather forecast rain, snow, and sleet are expected?Both sleet and freezing rain develop using the same fundamental mechanism: liquid droplets in a layer of warm air above the surface descend into a layer of freezing air close to the ground.
When snowflakes fall through a thin layer of warm air, they only partially melt, resulting in sleet.
These slushy drops then refreeze as they fall through a thick layer of icy air above the surface, and when they finally make it to the ground, they do so as frozen raindrops that bounce as they hit the ground.
When rain falls through a chilly layer and directly on the ground, it freezes on contact and forms a layer of ice. This is known as freezing rain.
Therefore, Snow that falls from a cloud and melts as it passes through an upper layer before falling back through a lower layer below freezing is known as sleet.

Write about an experience, either real or imaginary using these words chemical energy, electric energy, kinetic energy, mechanical energy, nuclear energy, potential energy, radiant energy, seismic energy, sound energy, and thermal energy
Answer:
I stopped to think for a moment, and realized chemical energy is found in food. Then, I thought about how the other day when I saw lightning, that is an example of electric energy. Then I thought about how when throw a ball, that is a form of kinetic energy. The other day, when I was hammering a nail into a piece of wood, that was a form of mechanical energy. An example of nuclear energy would be the nuclear power plant by our house. Before my book fell off my table, this is an example of potential energy. The energy from the sun is an example of radiant energy. Volcanoes and earthquakes around the world are an example of seismic energy. Sound energy would be the balloon that I popped the other day. Thermal energy would be the heat I feel from the heater.

B. glycolysis
C. cellular respiration
D. dehydration synthesis
Answer:
C. cellular respiration
Explanation:
Yeast produces the carbon dioxide responsible for bread rising by CELLULAR RESPIRATION
WHICH ORGANISM IS CALLED YEAST?
Yeast is an eukaryotic unicellular organism that belongs to the kingdom fungi. Cellular respiration is the metabolic process by which living organisms obtain energy in form of ATP by breaking down organic and inorganic substances.HOW DOES YEAST RESPIRE?
Yeast respires anaerobically via a kind of cellular respiration called FERMENTATION. In the process of fermentation, glucose is broken down to produce ethanol and carbon dioxide (CO2). In bread making, yeast is used to make dough rise. The carbon dioxide (CO2) produced during cellular respiration is what is responsible for the rising of bread.Learn more at: https://brainly.com/question/3126347

What type of organic compound is used to store and release large amounts of energy?
Answer:
A carbohydrate is an organic compound such as sugar or starch, and is used to store energy. Like most organic compounds, carbohydrates are built of small, repeating units that form bonds with each other to make a larger molecule. In the case of carbohydrates, the small repeating units are called monosaccharides.

Answer:
B. Paternity
Explanation:
Edge 2020
The career that combines DNA technology and forensics is paternity testing. The correct option is B.
What is paternity testing?DNA testing examines an individual's DNA banding patterns to determine the identity or mutations of a specific gene.
Paternity testing is a type of DNA testing that is used to determine paternity and the true nature of a relationship.
The lab compares tissue samples from the mother, the child, and the man to determine what unique characteristics known as genetic markers the child shares with the mother and the man who may be the father.
The chromosomes that determine the gender of the baby (X and Y chromosomes). The mother's egg typically contributes an X chromosome, while the father's sperm contributes either an X or a Y chromosome.
These tests are extremely accurate in determining whether a man is the biological father of a child.
Thus, the correct option is B.
