Answer:
Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. Many processes or methods are there to form new organism like binary fusion, budding, spore formation etc.
Explanation:
Binary fusion is one of the asexual reproduction. Example: Bacteria, Amoeba.
In the graph below, which letter represents the activation energy of a catalyzed reaction and why?
Choose 1 answer:
(Choice A) Y; the activation energy is reduced in a catalyzed reaction
(Choice B) X; the activation energy is greater in a catalyzed reaction
(Choice C) X; the activation energy is greater in an uncatalyzed reaction
(Choice D) Y; the activation energy is greater in an uncatalyzed reaction
Report a problem
Answer: Choice C) X; the activation energy is greater in an uncatalyzed reaction
Explanation: I got this question on khan academy.
The option that represents the activation energy of a catalyzed reaction is C. X; the activation energy is greater in an uncatalyzed reaction.
Activation energy simply means the minimum amount of energy that should be provided for compounds that'll result in a chemical reaction.
It should be noted that the activation energy for uncatalyzed conversion to the products will be more than that of the catalyzed reaction. In this case, X; the activation energy is greater in an uncatalyzed reaction.

Help! In which stages of meiosis are the cells considered diploid?
Answer:
The cell is diploid because the homologous chromosomes are still located within the same cell membrane.
Explanation:
Answer:
homologous chromosomes are still located within the same cell membrane. Only after the first cytokinesis, when the daughter cells of meiosis 1 are fully separated, are the cells considered haploid
Explanation:
what is the primary difference between diffusion and osmosis
Long answer here!
In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.
The movement of particles (such molecules or ions) from a region of higher concentration to a region of lower concentration is known as diffusion.
Thus, It happens in a variety of media, including gases, liquids, and solids. The inherent propensity of particles to travel down their concentration gradient in search of equilibrium is the driving force underlying diffusion.
On the other hand, osmosis is a particular kind of diffusion that entails the passage of water molecules over a membrane that is only permeable in certain places. It happens when the solute concentrations on opposite side of the membrane differ.
Thus, The movement of particles (such molecules or ions) from a region of higher concentration to a region of lower concentration is known as diffusion.

Some tools contain permanent magnets. What two types of materials could these tools pick up?
A. Materials that contain a magnetic material, such as iron
B. Materials that contain glue or other adhesives
C. Materials that contain other magnets
D. Materials that contain a ceramic, such as glass
Permanent magnets are the objects producing the invisible magnetic field. The tools containing the permanent magnets will pick the magnets and iron. Thus, options A and C are correct.
What are permanent magnets?Permanent magnets are the magnetic field-producing materials that pull or repel the ferromagnetic materials towards or away from themselves. The magnetic field is produced from the internal magnetic material.
They are formed when the ferromagnetic objects are heated at high temperatures and have those properties for a very long time. These magnets can attract objects that have magnetic fields around them like iron and other magnets.
Therefore, a permanent magnet will attract magnets and magnetic materials like iron.

In general, how do sensory systems function?
Answer:
Sensory nervous system detects and encodes stimuli and then sends signals from receptors. (evidence below for a clearer answer)
Explanation:
"As a whole, the sensory nervous system detects and encodes stimuli and then sends signals from receptors, that is, sense organs or simple sensory nerve endings, to the central nervous system, that is, it transduces environmental signals into electrical signals that are propagated along nerve fibers."

How would a small, uncharged lipid move across the cell membrane?
o through simple diffusion, down the concentration gradient
O through simple diffusion, against the concentration gradient
o through facilitated diffusion, down the concentration gradient
O through facilitated diffusion, against the concentration gradient
Answer:
Through simple diffusion, down the concentration gradient.
Explanation:
The phospholipids of the membrane are amphipathic with hydrophillic heads and hydrophobic tails. Other polar molecules cannot go through this hydrophobic interior. Since small uncharged lipids are non polar and hydrohobic, they are able to go through the membrane without the help of transport proteins. Therefore, the last two options can be ruled out because facilitated diffusion includes the use of a protein. Diffusion involves molecules moving down the concentration gradient so the second option can be ruled out.

Explanation:
During winter's freezing temperatures, some plants can remove water from their cells to reduce the amount of water that will freeze inside them. Why would plants need to do this
Answer:
The expansion of excess water as it turns to ice inside the cells would break the cells apart
Explanation:
We know that water expands anomalously. It expands between 4- 0°C.
Hence water expands upon freezing. Ice has more volume than liquid water and takes up more space in plant cells.
The expansion of excess water as it turns to ice inside the cells would break the cells apart
