Suppose you try to heat your house using a fireplace in one of the rooms. Would a fan be helpful?
Answer:
Yes it will
Explanation:
If You Have a Fireplace or Wood-Burning or Pellet-Burning Furnace. First, if you also have forced air, turn the fan on to help circulate heat. Make sure your ceiling fans rotate clockwise so they pull cool air up off the floor and push warm air down. And also keep them running at their lowest speed.

Difference between seedling and germination
Answer:
Explanation:
A seedling is a young plant grown from a seed in the nursery for the purpose of transplanting, while germination is the process of beginning growth from a seed or spore. In germination plants and fungal species, seeds sprouts to produce a seedling and the formation of spores. The stages of germination include, increase water imbibition into the seed, activation of metabolic activities, and protrusion of the radicle.

How would you finish the last sentence? What would you say to Sherman so he understands that velocity and force are different? Write a response and be prepared to share it with a partner.
Answer:
Velocity is a speed while force is a push or pull.
Explanation:
Velocity refers to the speed of an object in a specific direction whereas force is a push or pull in order to move an object one place to another. When we apply force on an object, the object moves in the direction of force applied so this moving is known as velocity. The unit of velocity is meter/ second whereas unit of force is newton which is equal to kilogram meter / second square.

If someone stole your DNA, could they steal your identity?
Yes
Criminals might steal DNA to use the genetic identity of their victim
Answer:
yes and no
Explanation:
if someone actually stole your DNA you wouldn't be alive right now,
but if someone stole "parts" of your DNA you would still be the same person because it doesn't matter what you look like you are your own person an example of this are identical twins, identical twins share the same exact DNA but they aren't the exact same person since they both can like different stuff and have different personalities. but if you mean in a biological stand point "if someone stole your DNA, could they steal your identity" of course not, at least not with our technology.

What is the function of each of these structures in the cell membrane? a) phospholipid bilayer b) peripheral protein c) integral protein d) glycolipid & glycoprotein e) cholesterol
Answer:
The correct answers are described in the Explanation section.
Explanation:
The function of the structures in the cell membrane are as follows:
a) phospholipid bilayer: comprised of fatty acids and alcohol, the phospholipid bilayer acts as a hydrophobic barrier to avoid the uncontrolled transport of molecules and ions.
b) peripheral protein: they are proteins present in the external surface of the cell membrane. This proteins form temporary bonds between the cells and other molecules, attaching and detaching at specific times.
c) integral protein: this proteins have one part of its structure in the surface and other part within the cell membrane. They have different roles, including: receptors, transporters, linkers, channels, among others.
d) glycolipid & glycoprotein: proteins that have carbohydrate-bearing portions in its extracellular environment. They maintain the stability of the cell membrane and facilitate cellular recognition.
e) cholesterol: cholesterol structure helps to the packing of the phospholipids, which restricts the passage of the molecules.

Answer:
Catalysts
Explanation:
Both catalyze the reactions
DNA polymerase and RNA polymerase are enzymes. They belong to the catalyst category.
What type of macromolecule is RNA polymerase and DNA polymerase?
RNA polymerase is an enzyme that creates RNA and catalyzes the initiation and elongation of RNA chains from a DNA template.
RNA is formed by a process known as transcription.
DNA polymerase is a type of enzyme that is responsible for creating new duplicates of DNA, in the form of nucleic acid molecules.
Nucleic acids are polymers, which are big molecules produced up of smaller, repeating units that are chemically related to one another.

which part of thr mitochondrion does an electron transport chain occur?
Answer:
Electron transport chain is the series of the cycle of the transfer of electrons from the one complex to other complex of the cycle. Both oxidation and redo reaction occurs in the electron transport chain.
The process of electron transport chain occurs in the inner mitochondrial membrane. All the complexes and the substrate of the cycle are embedded in the inner mitochondrial membrane. ATP is produced by this cycle located in the inner mitochondrial membrane.
Explanation:
Because molecules will move from one side to another to come to an equilibrium, or balance of concentration, the _________________________moves from side B to side A, so the water level on side A goes _____________________________.
Answer:
Water, up
Explanation:
In the process of movement water in the diffusion of water the net movement of water goes from higher concentration to the low concentration area. The movement of water move form one side to other side until it reaches an equilibrium and the level of water on the other side goes up.
Hence, the water molecule will move from from side B to side A until it reaches equilibrium and the water level on side A goes up.

5) Two Monsters, Hagatha and Urman, are expecting a child together. Hagatha is Hetero-zygous for Sharp claws, while Urman is Homo-zygous Recessive for Dull claws. Which of the following correctly identifies the Genotypes of both monsters? (use D or d to represent claw alleles)
a. Hagatha is Dd, Urman is dd
b. Hagatha is Dd, Urman is DD
c. Hagatha is DD, Urman is Dd
d. Hagatha is DD, Urman is dd
2 = d
3 = a
4 = a
5 = a
I am not so familiar with 1 and 3 sry
Homzygous means two identical alleles so a and c are both homzygous
recessive genes are not expressed if a dominant allele is present but with be expressed if the no dominant allele is present.
If you do a cross test you can determine the percentage.
Hagatha is heterozygous meaning non identical allele like Dd or dD and the other is homzygous recessive meaning that it has identical allele like DD or dd but it's recessive so it's dd.

what are the two main organs involved in the respiratory system?
Answer: The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are also part of the respiratory system.
Explanation: Your respiratory system is the network of organs and tissues that help you breathe. This system helps your body absorb oxygen from the air so your organs can work. It also cleans waste gases, such as carbon dioxide, from your blood. Common problems include allergies, diseases or infections.
What is the respiratory system?
The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.
