iodine test

We can test for starch with the help of an iodine test. Soak any food items, namely potato, in drops of iodine for some time. If it turns blue-black afterwards, it contains starch. The liquid used for testing starch is an iodine solution.

The typical human chromosome has about 150 million base pairs that the cell replicates at the rate of 50 pairs per second.

A chromosome is a thread-like structure present in the nucleus of cells such as plant, animal and human cells and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.

It is composed of three components, DNA, proteins and RNA,  amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.

Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).

The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome  is present in two forms such as Euchromatin and Heterochromatin.

Answer:

the gas starts to bow

Explanation:

The flow rate through capillaries affect the gas exchange rate between the blood in capillaries and interstitial fluid by gas starts to blow.

In terms of nutrition, interstitial fluid serves as a sort of refueling station for our cells. Salt, fatty acids, glucose, and minerals like calcium, magnesium, and potassium are all present in interstitial fluid.

Blood capillaries are where the nutrients in interstitial fluid are obtained. Additionally, metabolic waste products can be stored in interstitial fluid.

A continuous glucose monitor will use a formula to offer a near estimate of what our blood glucose level is likely to be at that particular moment because the glucose level in interstitial fluid is not exactly the same as that in our blood.

Therefore, The flow rate through capillaries affect the gas exchange rate between the blood in capillaries and interstitial fluid by gas starts to blow.

Answer:

Blood in the urine is correct

Explanation:

Answer:

negative, salt

Explanation:

ADH functions via a negative feedback mechanism that responds to blood salt concentration to maintain homeostasis.

In order to maintain a constant state between internal conditions and the external environment, a cell's response to its environment is known as homeostasis.

Because of their complexity and uniqueness to living things, the coordinated physiological responses that keep the majority of the body's dynamic equilibrium in place have been given the name "homeostasis."

Ex: When it's cold outside, we start to shiver and use energy to stabilize our body temperature. This is where the cell regulates cell temperature, fluid balance, sugar balance, etc. through it.

Therefore, there is negative feedback that responds to blood salt concentration.

The movement of water across cellular membranes through aquaporins is known as osmosis. Water moves down the concentration gradient. The fourth option is the correct answer.

Molecules can pass the cell membrane both actively and passively. In passive transport, no energy or ATP is required. Molecules can move from a higher concentration to a lower concentration.

Diffusion and osmosis are examples of passive transports. In diffusion, gases and other small molecules pass the cell membrane from a higher to a lower concentration. Water is a polar molecule, so it doesn't pass the membrane due to its nonpolar nature. Cells have aquaporin channels that are made for water.

Through aquaporins, water passes into the cell. This is called osmosis. In active transport, energy is required. When a molecule passes from a lower concentration to a higher concentration, energy is needed. An example is sodium-potassium ATPase.

Hence, the correct answer is osmosis. The fourth option is the correct answer.
