Answer:
A. DNA polymerase pairing A with G
Explanation:
Adenine (A) always pairs with thymine (T), and cytosine (C) always pairs with guanine (G).
DNA polymerase pairing A with G would cause an error in DNA replication. The correct option is A.
An error in DNA replication occurs when an incorrect nucleotide is inserted during the replication process.
DNA polymerase is responsible for synthesizing a new DNA strand by adding complementary nucleotides to the existing template strand.
It ensures the accuracy of replication by matching each nucleotide with its complementary partner (A with T and G with C).
If DNA polymerase pairs A with G instead of A with T, it results in a mismatched base pair.
This is considered an error in DNA replication since it introduces a mutation in the newly synthesized DNA strand.
The fidelity of DNA replication relies on the correct base pairing and proofreading mechanisms of DNA polymerase to minimize errors and maintain the integrity of the genetic information.
Thus, the correct option is A.

“How might an energy requirement affect an individual who has a cancerous tumour?”
Answer:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function. Energy is stored in the bonds of glucose (like a stretched rubber band), and when glucose is broken down, much of that energy is released. Some of it is captured in a form that can be used to do work in cells - a molecule called adenosine triphosphate or ATP. The energy that is not captured in ATP is usually given off as heat (one of the things that helps us maintain our normal body temperature).

Kamar is looking for his birth mother. Kamar knows that his blood type is AB and his father’s blood type is heterozygous A. What can Kamar assume about his mother’s blood type?(1 point)
-Kamar’s mother must be either AB or B because blood types AB is considered codominant.
-Kamar’s mother must be AB because blood type AB is inherited from one parent.
-Kamar’s mother must be O because the recessive allele allows for Kamar to get type A from his father.

What color would the bby and water turn with plants in the dark
Answer:
The water is drawn in the xylem through capillary action and is dispersed through out the entire plant from stem to tips of the leaves and petals. When the water is colored, the color from the water can stain the plant, especially if it is a light colored plant, such as the white petals on our flowers.

What is the function of erythrocytes?
What is the term for all the components of the blood?
What is blood?
Answer:
1. The main physiological role of red blood cells (RBCs), or erythrocytes is to transport of gases (O2, CO2) from the lung to the tissues and to maintain systemic acid/base equilibria. In addition, RBCs are well equipped with antioxidant systems, which essentially contribute to their function and integrity.
2. In humans, it includes plasma (the liquid portion), blood cells (which come in both red and white varieties), and cell fragments called platelets. Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in.
3.Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.

why is the late Cambrian thought of as the period of the greatest evolutionary change in life forms on earth's history?
Answer:
The Cambrian Period marks an important point in the history of life on Earth; it is the time when most of the major groups of animals first appear in the fossil record. This event is sometimes called the "Cambrian Explosion," because of the relatively short time over which this diversity of forms appears.

Which structure does the immune system target in type 1 diabetes?
a. beta cells of the pancreas
b. liver cells that release glucose
c. insulin receptors on fat cells
d. red blood cells in the bloodstream
Answer:
The thymus plays an important role in deletion of potentially autoreactive T cells. However, the presence of islet-specific T cells in the circulation of type 1 diabetes patients and healthy subjects indicates that the thymus is not capable of efficiently deleting all autoreactive T cells (Mathis and Benoist 2009).

Humans burn fossil fuels and wood, releasing carbon dioxide into the atmosphere. This carbon dioxide is then absorbed by trees for photosynthesis. These processes are contributory to which chemical cycle?
Carbon cycle controls the amount of carbon dioxide in the atmosphere. These processes are contributory to the carbon cycle in the environment.
What is a carbon cycle ?
The carbon cycle is nature's method of recycling carbon atoms, which repeatedly go from the atmosphere into Earth's living things and back into it. The majority of carbon is preserved in rocks and sediments; the remainder is preserved in the ocean, the atmosphere, and living things.
Life on Earth is reliant on the carbon cycle. The quantity of carbon that is naturally released from reservoirs is equal to the amount that is naturally absorbed by reservoirs because nature tends to maintain carbon levels in balance. This carbon balance must be preserved for the earth to continue to support life.
Therefore, the carbon cycle is an important chemical cycle.

Bobcats are generally solitary and establish territories of a certain size where they hunt for food. What type of population dispersion would you expect bobcats to have?
Answer:
Uniform dispersion.
Explanation:
The bobcats' population distribution would be a uniform dispersion because they are distributed in an area in a balanced way. That is to say, that there is space between them and that each bobcat establishes its personal space when hunting and for their daily life. As they are solitary animals, they do not live in groups and only associate with other bobcats to reproduce themselves.

4. What are sensory organs and what type of stimuli do these receptors respond to?
5. What is an explanation of how the information from stimuli is communicated to the brain?
6. What is a description of the two things that can happen when the brain processes the information from stimuli?
Hello, 3Coli Here!
Here are your answers:
1. What is a stimulus?
Stimulus is a natural body reaction caused by changes in the environment around or inside the organism. This is a response from the brain.
2. Why does the body respond to stimuli?
The body responds to stimuli, because it needs to protect itself.
3. What are some different types of stimuli?
The two main types of stimuli are external stimuli and internal stimuli. External stimuli are reactions triggered by changes that occur outside of the body, while internal stimuli are reactions triggered by changes inside of the body.
4. What are sensory organs and what type of stimuli do these receptors respond to?
The most commonly used sensory organs include Eyes, Ears, Tongue, Nose, and Skin. Eyes respond to light and motion, because they are used to see. Ears respond to sound, because they hear. The tongue is used to taste, so it senses flavors. The nose is used to smell, so it responds to scents. Finally, the skin is used to feel, so it responds to whatever it feels.
5. What is an explanation of how the information from stimuli is communicated to the brain?
Neuron receptors convert internal and external environments into electrical signals, and then is sent to the brain through nerves.
6. What is a description of the two things that can happen when the brain processes the information from stimuli?
After the brain receives the signal, it will provide a response. One type of response is that the body will physically react to the change. The second type of response is to avoid the change.
