Question 9 of 25
Carbon dioxide can build up as waste and disrupt a cell's homeostasis. Which
statement best describes how a cell gets rid of excess carbon dioxide?
A. Carbon dioxide molecules pass through the phospholipid layers to
exit the cell by diffusion.
OB. The cell forms vesicles around carbon dioxide molecules, which
merge with the cell membrane.
C. Mitochondria use carbon dioxide to make simple sugar molecules.
OD. Osmosis allows water to enter the cell, forcing some of the carbon
dioxide out.
Carbon dioxide molecules pass through the phospholipid layers to exit the cell by diffusion is the correct statement that describes how a cell gets rid of excess carbon dioxide (Option A).
What is transport by simple diffusion?Transport by simple diffusion refers to a type of trsnpor across the cell membrane which does not require energy and functions to move substances in favor of a concentration gradient.
Carbon dioxide moves across the cell membrane by using the process of simple diffusion since the external media contains lower concentration of this element, which in the cell is a byproduct of the chemical aerobic reactions (i.e. chemical reactions performed in presence of oxygen) collectively known as cellular respiration .
In conclusion, carbon dioxide molecules pass through the phospholipid layers to exit the cell by diffusion is the correct statement that describes how a cell gets rid of excess carbon dioxide (Option A).

b. Cooling it.
c. Dropping it repeatedly on the ground.
d. Heating it.
The magnetic field of a magnet is strongest
a. at its north pole.
b. at its south pole.
c. in the middle.
d. at both of its poles.
The answers include the following:
The following which is "not" likely to cause a magnet to lose its magnetism is cooling it and is therefore denoted as option B.The magnetic field of a magnet is strongest at at both of its poles and is denoted as option D.What is a Magnet?This is referred to as a material or object that produces a magnetic field and it has two poles which are the North and south poles in which the magnetic field of a magnet is strongest.
Cooling a magnet will not cause a magnet to lose its magnetism but instead the magnetism will increase because the molecules within the magnet will move slower because they have less kinetic energy so there is less vibration within the magnet's molecules thereby resulting in more concentrated magnetic field that strengthens the magnet.

how does the number of = bonds change the melting point?
The number of double bonds in a molecule generally decreases its melting point.
How is the melting point affected ?The presence of double bonds in a molecule generates a more planar structure, reducing its capacity to tightly bundle molecules in the solid state.
Consequently, this yields lower intermolecular forces between them and leads to a commensurate decrease in melting point. On the other hand, single bonded molecules tend to take on a three-dimensional contour, thereby facilitating their denser packing that spawns greater intermolecular forces thus yielding higher melting points.

Single division of chromosomes.
Two divisions of chromosomes.
Crossing over and independent assortment occurs.
Mitosis and Meiosis include Duplicate DNA, Meiosis includes make genetically different cells, crossing over and independent assortment occurs., and two divisions of chromosomes and Mitosis includes a single division of chromosomes.
What is the cell process of mitosis?The cell process of mitosis is a cell division phenomenon that generates two genetically identical daughter cells as the parental cell, while meiosis generates four daughter cells that have half genetic material when compared to the parental cell which are called gametes or germinal meiotic cells that fuse during the process of fecundation in order to develop a diploid cell and thus restore the normal number of chromosomes in somatic cells.
Therefore, with this data, we can see that the cell process of mitosis and meiosis are different in the sense mitosis involve one division cycle while meiosis involves two division cycles and it generates 4 daughter cells.

He uses a calorimeter to accurately measures the transfer of thermal energy by measuring changes in the temperature of the system. The calorimeter allows him to study how the temperature changes when mixing liquids at different initial temperatures as well as how it changes when adding objects at different temperatures to water. In both cases, the warmer substance transfers thermal energy to the cooler until the substances reach equilibrium.
What is the transfer of thermal energy about?Investigating the transfer of thermal energy when two components of different temperature are combined within a closed system involves studying how heat flows between the two components until they reach thermal equilibrium.
Hence, In a closed system, the total energy remains constant, but the energy can be transferred between the components in the form of heat. This process is governed by the laws of thermodynamics, which describe the relationships between heat, energy, and work.

Describe the mechanism of glycolysis in detail
The process of Glycolysis is a catabolic process in which two molecules glucose goes through a ten- step pathway and yield two molecules of pyruvate . It is a major part of carbohydrate metabolism .
Mechanism Of Glycolysis
The glycolysis is also known as EMP pathway and it is involved in both aerobic and anaerobic conditions .There are two phases in the mechanism of glycolysis in which 5 reactions takes place in each phase and the process of glycolysis takes place in cytosol
Preparatory phase refers to the generation of two molecules of glyceraldehyde 3-phosphate from one molecule of glucose which further goes into the payoff phase . In this phase two molecules of ATP are used and two regulatory enzymes were involved in this reaction .
Payoff phase refers to the further break down of two molecules of glyceraldehyde3-phosphate to two molecules of pyruvate . In this phase four molecules of ATP and two molecules of NADH are generated . In this phase only one regulatory enzyme is involved which is the breakdown of PEP to pyruvate .

Suppose the half-life of an isotope is 10 years. After how many years will half of this isotope have decayed into its daughter element? 5 years 20 years 10 years
Answer:
the answer is 10 years
Explanation:
An atom may contain an unstable nucleus that spontaneously transforms into a more stable form by emitting particles and energy. Half-life is a measure of the time needed for one-half of the atomic nuclei of a given radioactive substance to decay in its radioactivity. This time is a constant and can be estimated as an exponential unit which is dependent on the type of radioactive isotope. For example, Carbon-14 (C14) is a radioactive isotope of carbon that has a half-life of 5730 years.
Answer:
The answer would be 10 years.

(b) Parasitism is a relationship of creatures where one life form is benefitted to the detriment of another. For instance, human lice on the scalp.
(c) Mutualism is a relationship between organisms in which both parties benefit. Legumes and Rhizobium are two examples.
(d) Competition between organisms of two distinct species for a common resource is referred to as interspecific competition. Take, for instance, the competition between leopards and lions over common prey.
(e) Predation occurs when one organism devours and kills another.
