Why is it necessary for a cells to have nucleus acids in its nucleus
Answers
It is necessary for cells to have nucleus acids in their nucleus because they carry the genetic blueprint of a cell and carry instructions for the functioning of the cell.
A nucleic acid is a chain of nucleotides that biological systems use to store genetic information. It produces the DNA and RNA molecules, which hold the data necessary for cells to produce proteins.
A "polymer" of "nucleotides," or a long molecule made up of them, is referred to as nucleic acid. All life on Earth needs nucleic acids to store genetic information; in other words, nucleic acids serve as the "source code" or fundamental blueprint for the creation of cells.
Your genetic information, which you acquired from your parents, is stored and transmitted by nucleic acids. Genes are unique pieces of nucleic acids that are in charge of creating every protein in your body.

Figure 1 represents a plasma membrane and molecules present on either side.
Part A: Describe the biological need for cells to be surrounded by a membrane that is selectively permeable for different materials.
Part B: Explain how the model shows selective permeability of the membrane to specific ions.
Part C: Describe the characteristics of the phospholipid bilayer that permit small hydrophobic lipid molecules to pass directly
Part D: Based on the model, explain whether the molecules shown crossing the membrane require energy to do so.
Answers
Answer:
A. Cell membrane is the outer layer of the cell that plays a role as the barrier between the internal and outer environment of the cell by regulating by allowing particles or substances to enter or exit the cell. It helps in maintaining the internal environment of the cell by allowing certain molecules to enter and stop other molecules.
B. Phospholipids bilayer is the part of the plasma membrane that makes it selective permeable. The plasma membrane does not allow ions with charges on the side of the molecules directly sodium, potassium, and many other ions are examples of this. Ions can enter or exit the cell with the help of the transporters or complexes.
C. There is hydrophilic-head and hydrophobic-tail present in the phospholipid bilayer in the structure of the cell membrane which makes it selectively permeable.
D. For active transport of molecules, the movement of molecules is always against the gradient which means movement from lower concentration to a region of higher concentration that requires energy (ATP).
Which statement describes prey?

Explanation:
They are killed by predators for energy.
Check all that are true of the following scenario.
An archer strings an arrow on a bow and draws the string back. Aiming the bow
upwards at a 45 degree angle, the archer pauses with arms locked into position and
then releases the string. The arrow flies upwards making an arc and then sticks into
the trunk of a tree with an audible thud.
At least four different types of energy are illustrated in this example.
The first energy transformation in the scenario is chemical energy to kinetic.
From the time the archer draws the bow until the thud us heard, entropy increases in
the universe.
The energy of the arrow at the end of the scenario is equal to the energy exerted by the
muscles of the archer.
When the arrow sticks into the tree the original energy has all been used up.
Answers
Statements 1 and 3 are true, while statements 2 and 4 are false.The first energy transformation in the scenario is chemical energy to kinetic. - True.
The archer converts chemical energy stored in their muscles into kinetic energy when they release the string and propel the arrow forward.From the time the archer draws the bow until the thud is heard, entropy increases in the universe. - False. Entropy is a measure of disorder or randomness in a system. In this scenario, the archer's actions do not necessarily lead to an increase in entropy.
The energy of the arrow at the end of the scenario is equal to the energy exerted by the muscles of the archer. - False. Energy is conserved in a closed system, but some energy is lost as heat and sound during the process. Therefore, the energy of the arrow at the end may be less than the energy exerted by the archer's muscles.
When the arrow sticks into the tree, the original energy has all been used up. - False. Energy is not created or destroyed but rather transformed from one form to another. Some of the initial energy from the archer's muscles is transferred to the arrow's kinetic energy, but it is not entirely used up.In summary, statements 1 and 3 are true, while statements 2 and 4 are false.

Briefly tell about the cells life cycle
Answers
Answer:
Cell cycle is the name we give the process through which cells replicate and make two new cells. Cell cycle has different stages called G1, S, G2, and M. G1 is the stage where the cell is preparing to divide. To do this, it then moves into the S phase where the cell copies all the DNA. So, S stands for DNA synthesis. After the DNA is copied and there's a complete extra set of all the genetic material, the cell moves into the G2 stage, where it organizes and condenses the genetic material, or starts to condense the genetic material, and prepares to divide. The next stage is M. M stands for mitosis. This is where the cell actually partitions the two copies of the genetic material into the two daughter cells. After M phase completes, cell division occurs and two cells are left, and the cell cycle can begin again.

What does the energy pyramid demonstrate?
OA. A great amount of energy is gained moving up the energy pyramid.
OB. Energy is not transferred between organisms in an ecosystem.
OC. The same amount of energy is available at every level of the energy pyramid.
OD. A great amount of energy is lost traveling up the energy pyramid.
Answers
The energy pyramid demonstrate a great amount of energy is lost traveling up the energy pyramid.
The energy pyramid demonstrates that as you move up from the producers (bottom level), which convert sunlight into energy through photosynthesis, to the primary consumers (herbivores), to the secondary consumers (carnivores that eat herbivores), and finally to the tertiary consumers (carnivores that eat other carnivores), there is a decrease in available energy.
This is because energy is lost at each level through processes such as respiration, heat loss, and waste. Therefore, the top predators of an ecosystem have access to the least amount of energy.

HELP! What happens to an object's mass as the object's acceleration increases but the force stays the same?
Question 1 options:
The mass is zero
The mass increases
The mass stays the same
The mass decreases
Answers
Answer:
The mass decreases
Explanation:
As the acceleration of an object increases, and the force stays the same, the mass decreases in retrospect.
This is because of newton's second law of motion which posits that, "force is the product of mass and acceleration".
In a body, acceleration and mass are inversely proportional to one another. As the mass increases, acceleration reduces and vice versa.
