Full synthetic and synthetic blend refer to types of engine oils used in vehicles. Full synthetic oil is made entirely from chemical compounds and has no natural or conventional base oils. This type of oil is designed to provide the highest level of protection and performance for modern engines.

Full synthetic oil offers better viscosity performance in extreme temperatures, better fuel efficiency, and longer oil change intervals. It also resists breakdown better than conventional oils and provides better engine cleanliness.

Synthetic blend oil, also known as semi-synthetic oil, is a combination of synthetic and conventional base oils. The ratio of synthetic to conventional oil varies depending on the brand and product.

Synthetic blend oil is designed to provide some of the benefits of full synthetic oil while being more affordable than a full synthetic oil change. It has improved performance compared to conventional oil, but not as much as full synthetic oil.

Overall, full synthetic oil is the highest quality and provides the best performance and protection, while synthetic blend oil offers some benefits of synthetic oil at a more affordable price point.

The choice between the two ultimately depends on the specific needs of the vehicle and the driver's preferences.

The net working capital for the firm is $1,500, calculated by subtracting current liabilities from current assets, the correct option is (e).

To calculate the net working capital, you need to subtract the current liabilities from the current assets.

In a company's financial statements, the formula for calculating current assets can be expressed as the sum of inventory, accounts receivable, and cash.

Current Assets = Inventory + Accounts Receivable + Cash

Current Liabilities = Accounts Payable

Using the given values:

Current Assets = $820 (Inventory) + $1,210 (Accounts Receivable) + $360 (Cash)

= $2,390

Current Liabilities = $890 (Accounts Payable)

The formula to calculate Net Working Capital is derived by subtracting Current Liabilities from Current Assets.

Net Working Capital = Current Assets - Current Liabilities

Net Working Capital = $2,390 - $890

= $1,500

Therefore, the amount of net working capital is $1,500.

Hence, the correct option is (e).

Substitutions are base mutations where occurs replacement, insertion refers to the add bases and deletion is when nucleotide bases are removed.

A mutation is the alteration of the linear order of nucleotides in the genome of a given organism. Deletion occurs when nucleotides are eliminated from the chain, insertions refer to the emergence of new nucleotides that enlarges the chain and substitution refers to the replacement of nucleotides such as for example adenine for thymine.

Therefore, with this data, we can see that mutations can produce different phenomena which include insertions, deletions and substitutions.

Like any cladogram, we have traits that will mark differences among groups and will allow us to solve phylogenies, in this case, each dot is a trait, so if we look at the point where amphibians diverge from the rest of the groups we have four limbs, therefore the correct answer is option 1.

The removal of the RNA primer and addition of DNA nucleotides to the 3' end of Okazaki fragments in its place is carried out by DNA polymerase I.

During DNA replication, RNA primers are synthesized by primase to initiate DNA synthesis. These RNA primers are then removed by the exonuclease activity of DNA polymerase I, and the resulting gap is filled in by DNA polymerase I, which adds the appropriate DNA nucleotides to the 3' end of the adjacent Okazaki fragment. DNA ligase then seals the nick between the adjacent fragments. This process is known as DNA lagging strand synthesis or the Okazaki fragment processing. DNA polymerase I also has a 5' to 3' polymerase activity, which helps in filling gaps that are created when the RNA primers of the leading strand are removed.

Answer:

The banding pattern on a stained gel.

Explanation:

If we take point C closer towards point B, then  ∠ABC will remain the same, the measurement of ∠BAC will decrease, and the measurement of ∠ACB will increase. Similarly, If we take point C far from point B, ∠ABC will remain the same, the measurement of ∠BAC will increase, and the measurement of ∠ACB will decrease.

Angle is formed by two lines or rays which have a common endpoint. Angle has two sides.

Here Given in the question that Point C is movable and it moves towards point B.

If we change the position of C nearer to point B keeping points B and A fixed in angle ∠ABC the side BC length will decrease but the gap between AB and BC will remain the same.  Therefore ∠ABC will remain the same.

If we change the position of C nearer to point B keeping point B and A fixed in angle ∠BAC, point C will get closer to point B for which the gap between AB and AC will decrease. Therefore the measurement of ∠BAC will decrease.

If we change the position of C nearer to point B keeping points B and A fixed in angle ∠ACB, point C will get far from point A as point A is fixed for which the gap between AC and CB will increase. Therefore the measurement of ∠ACB will increase.

Therefore if we take point C closer towards point B, then  ∠ABC will remain the same, the measurement of ∠BAC will decrease, and the measurement of ∠ACB will increase.

If we take point C far from point B, then the thing will be reversed except ∠ABC.

Therefore If we take point C far from point B, ∠ABC will remain the same, the measurement of ∠BAC will increase, and the measurement of ∠ACB will decrease.

The water potential given the ionization constant for NaCl = 2.0 will be 16.66986 bars.

In a solution or liquid, the equilibrium between ions and non-ionized molecules determines a constant known as an ionization constant (with the symbol K). It is either the ratio of the product of concentration to the reactant or the ratio of products and reactants increased to the proper stoichiometric powers.

The best approach to describe a solute concentration within a solution is by molar concentration. The total number of moles of solute dissolved in one liter of solution is referred to as molarity

The water potential will be:

Water potential = - iCRT

i = ionization constant = 2 (given)

C = molar concentration = 0.34M

R = Pressure constant = 0.0831 Litre bars/mole-K

T = Temperature in Kelvin = 22+273 = 295 K

Therefore, the water potential will be:

= -2 x 0.34 x 0.0831 x 295

Overheating and dehydration during marathon can be prevented by wearing pre-cooling vests and drinking adequate amounts of fluids.

Dehydration is the excessive loss of water in the body. This can happen due to less intake of water, due to some disease or during heavy workouts.  During workouts the body produces heat to burn the calories and therefore to cool down the body, water is released in the form of sweat.

Pre-cooling vests are the type of vests that can be wore some time before any physical activity. In these vests, there are various pockets present where ice packs can be stored. This delays the production of excessive heat in the body and sweating. The vests can be wore during warm-up but must be removed during excessive physical activities.

The correct order of structures as you move from the outside a muscle cell to deep inside is, Fiber, Myofibril, Myofilament.

Myocytes, also known as muscle cells, are the cells that comprise muscular tissue. There are three types of muscle cells in the human body: cardiac, skeletal, and smooth.

Skeletal muscle cells are multi-nucleated, long, cylindrical, and striated. Each nucleus is in charge of the metabolic requirements of the sarcoplasm that surrounds it. Skeletal muscle cells require a lot of energy, so they have a lot of mitochondria to make enough ATP.

Sarcoplasm is composed of myofibrils that are composed of thick and thin myofilaments.

Cardiomyocytes have a small, thin, rectangular shape. They have a single nucleus, cell organelles similar to skeletal muscle cells, and a large number of sarcosomes that provide energy for contraction. Intercalated discs, which have gap junctions for diffusion and communication, connect cardiomyocytes structurally.

Smooth muscle cells are striated, spindly in shape, and have a single nucleus in the center. Smooth muscle cells are stacked in sheets, allowing them to contract at the same time. They have poorly formed sarcoplasmic reticulum's and no T-tubules due to their small size.

The results have been different if you had used a cell type different from your cheek cells because of the absence of a cell wall in the cheek cell.

Like other animal cells, the cheek cells in humans lack a cell wall. A cell membrane that is partly permeable surrounds the cytoplasm. In comparison to plant cells, animal cells have denser, more granular, and bigger cytoplasms. The cheek cells are shaped irregularly because they lack cell walls. Animal cells typically have unusual shapes since only plant cells have cell walls.

 Animal cells, like those seen in the human cheek, lack a cell wall. The outer barrier of the human cheek cell is thus the cell membrane, a semi-permeable barrier. In contrast to onion cells, human cheek cells have a rich cytoplasm. It is granular and takes up a lot of space inside the cell.
