Answer:
Inertia is directly proportional
Explanation:
Inertia increases as the mass of an object increases. Inertia is directly proportional to the mass, that is, inertia increases with the increase in the mass and decreases with the decrease in the mass. The SI unit of the mass is kg and the SI unit of the inertia is also kg.
Answer:
Objects with more mass have more inertia. Consequently, a very large rock will be harder to move than a small pebble. The same way, once the large rock starts to move, it will be harder to stop than the small pebble. MOMENTUM is a measure of inertia of motion. Then momentum relies on mass and velocity. We define momentum as the product of mass and velocity: m * v.

.Which muscle trait is the ability to be stretched and lengthened?
A. Excitability
B. Contractability
C. Extensibility
D. Elasticity
The muscle trait that refers to the ability to be stretched and lengthened is C. Extensibility.
Muscle is a tissue that is mostly made up of specialised cells and fibres that may contract to cause movement. There are three types of muscles found in the human body : Skeletal Muscles, Smooth Muscles and Cardiac Muscles. The muscles exhibit four muscle traits : excitability, contractability, extensibility, elasticity. The muscular system as a whole carries out various crucial tasks thanks to these characteristics. These include the generation of motion and force, maintenance of body posture and stature, stability of joints, generation of body heat (to maintain a normal body temperature), and giving the body shape. Extensibility allows a muscle to be stretched without being damaged and to return to its original length after the stretching force is removed i.e, to get lengthened.

A cultured colony of E. coli bacteria is doubling every two hours. A microbiologist estimated that the original population was just one cell which weighed 9.5 x 10-15 Kg. What is the mathematically predicted mass of this colony after three full days of growth?
A cultured colony of E. coli bacteria is doubling every two hours and the original population was just one cell which weighed 9.5 x 10-15 Kg. The mathematically predicted mass of the E. coli colony after three full days of growth is 3.78 x 10-5 Kg.
First, we need to determine the number of doublings that will occur in three days. Since the bacteria double every two hours, there are 12 doublings per day (24/2). Therefore, there will be 36 doublings in three days (12 x 3).
Next, we can use the formula M = M0 x 2^n, where M is the final mass, M0 is the initial mass, and n is the number of doublings. Plugging in the given values, we get:
M = (9.5 x 10^-15 Kg) x 2^36
Simplifying this equation, we get:
M = 3.78 x 10^-5 Kg
Therefore, the mathematically predicted mass of the E. coli colony after three full days of growth is 3.78 x 10^-5 Kg, which is the answer we were looking for.

Which diagram number below represents the liquid layers in the cylinder?
(K) Karo syrup (1.4 g/mL), (V) vegetable oil (0.91 g/mL,) (W) water (1.0 g/mL). Support your answer with a brief explanation.
Answer:
Diagram 1
Explanation:
The correct diagram that depicts the liquid layers in the cylinder would be diagram 1.
The density of a substance is a measure of how heavy the substance is. Hence, a liquid that is heavier than water (with higher density) would sink in water while a liquid that is less dense than water would float on it.
Therefore, based on the density of the karo syrup (1.4 g/mL), it would take the bottom space in a cylinder, followed by water (1.0 g/mL) while vegetable oil with 0.91 g/mL would float on the former two.
The correct diagram is 1.
Which of the following is a correct sequence of events in cellular respiration?
The correct sequence of events in cellular respiration is option a: glycolysis, citric acid cycle, electron transport chain.
During cellular respiration, glucose is broken down to produce energy in the form of ATP. The process starts with glycolysis, which occurs in the cytoplasm and involves the breakdown of glucose into pyruvate molecules. Glycolysis generates a small amount of ATP and NADH.
The pyruvate molecules produced in glycolysis enter the mitochondria, where the citric acid cycle, also known as the Krebs cycle, takes place. In this cycle, the pyruvate is further broken down, releasing carbon dioxide and generating NADH and FADH2 as electron carriers. The citric acid cycle also produces a small amount of ATP.
The electron carriers NADH and FADH2 then participate in the electron transport chain, which is located in the inner membrane of the mitochondria. In the electron transport chain, the electrons from NADH and FADH2 are transferred through a series of protein complexes, creating a flow of electrons that drives the synthesis of ATP. This process is known as oxidative phosphorylation.
Therefore, the correct sequence of events in cellular respiration is glycolysis, citric acid cycle, and electron transport chain, as stated in option a.

true/false: below the lithosphere, terrestrial planet mantles are primarily melted rock (magma).
True, below the lithosphere, terrestrial planet mantle is the layer of interior that lies beneath the crust and outer core.
Above the lithosphere, terrestrial planet mantles are primarily melted rock (magma) is because there aren't many SiO2 molecules that could be converted into glass by heat and pressure at great depths in the mantle—only CaO molecules can do so under these conditions (and they don't do it very well)..
The mantle has a thick upper mantle and a thin lower mantle. The upper mantle is where most of the crust forms, because it contains relatively large amounts of silica from which the crust can grow. The lower mantle has a much higher proportion of iron and magnesium than the upper mantle does, and it also contains small quantities of silicon-30 (SiO2) and calcium-40 (CaO).

why are there no chloroplasts contained within the cells of the onion, even though they are plant cells?
There are no chloroplasts contained within the cells of the onion, even though they are plant cells because energy is stored in the onion fruiting body (bulb) rather than through photosynthesis.
A specialized organelle that is not found in animals is present in plants. Chlorophyll, a pigmented chemical, is found in these chloroplasts. This makes photosynthesis in plants easier and gives plants their typical green color.
Because the onion grows underground, the bulb does not contain chloroplasts. These organelles are not required if chloroplasts are not going to be exposed to sunlight because they are used to make sugar in the presence of sunlight. Instead, the onion begins its growth with energy reserves before producing a stem. The only chloroplasts in the plant are found in this greenery.

In noncyclic photophosphorylation, electrons flow in a one-way path from water to?.
In noncyclic photophosphorylation, electrons flow in a one-way path from water to NADP+.
Photophosphorylation refers to the phosphorylation of ADP to produce ATP during the photosynthesis process. Under aerobic and anaerobic conditions, cyclic photophosphorylation takes place, with sunlight serving as the primary source of energy for living things. The universal energy unit of life is a phosphate molecule called ATP, which is produced by all organisms. In photophosphorylation, protons are pumped across a biological membrane using light energy. This process is mediated by the movement of electrons through an electron transport chain. Proton gradient energy is stored in this way. ATP is produced from ADP and inorganic phosphate as the protons return through the enzyme ATP synthase. The Calvin cycle relies on ATP to help with the production of carbohydrates from carbon dioxide and NADPH.
Cyclic photophosphorylation is the name given to the photophosphorylation procedure that leads to the cyclic movement of electrons during the synthesis of ATP molecules. In this procedure, plant cells only convert ADP to ATP to provide the cells with immediate energy. Non-cyclic photophosphorylation is the name given to the photophosphorylation procedure that causes the electrons to move non-cyclically in order to synthesise ATP molecules using the energy from excited electrons supplied by photosystem II.

which one of the types of proteins interacts directly with a stop codon?
Release factor types of proteins interacts directly with a stop codon.
A release factor is a protein that allows for the termination of translation by recognizing the termination codon or stop codon in an mRNA sequence. They are named so because they release new peptides from the ribosome.
A stop codon (also known as a termination codon) is a codon (nucleotide triplet within messenger RNA) that indicates the end of the current protein's translation process in molecular biology, more specifically in protein biosynthesis. A stop codon signals the end of this process by binding release factors, which cause the ribosomal subunits to dissociate and release the amino acid chain. The majority of messenger RNA codons correspond to the addition of an amino acid to a growing polypeptide chain, which may eventually become a protein.
