andriy [413]

Answer:

Explanation:

$\text{We are to fill in the blanks with the correct words that best suit the blanks}$

$\text{Nuclei with an} \ \mathbf{odd} \ \text{number of protons and neutrons possess a property }$

$\text{called spin. Nuclear spin can be thought as either up or down with the spin }$

$\mathbf{magnetic \ field.}$

$\text{When a molecule is placed in an NMR, a large} \ \mathbf{magnetic} \ \text{field is applied making the }$ $\text{spin states become of unequal energy, with the spin that generates a magnetic field }$ $\text{in the same direction of the applied magnetic field being}\ \mathbf{ lower} \ \text{ in energy. The NMR }$ $\text{then uses} \ \mathbf{ radio \ frequency}\ \text{ to 'flip the spin' of each nuclei, wherein each nuclei will }$ $\text{require a specific energy level of radiation that corresponds to its difference in }$ $\text{energy of spin states, this is often called the nuclei's}\ \ \mathbf{resonance } \ \text{frequency, }$ $\text{which is measured by the NMR and translated to teh final spectra.}$

During a study testing a new screening tool for a chronic disease, an individual is screened for the disease and the test comes

katrin [286]

Answer:

False negative

Explanation:

If the test result comes out to be negative for a condition that is actually existing in reality, then such a test result is said to be false negative.
This means when the negative test result is incorrect, it can be called as a false negative.
Thus, the result would have been correct if the result would have come out to be positive.
In statistics false negative is considered as a type II error in which a test is conducted to check for a single condition and the result comes out to be negative even when the condition exists.
In the given situation, the person has a chronic disease but the screening test shows that the person does not have the disease and hence, this is an example of false negative.

How do aggregate fruits develop

Pani-rosa [81]

Aggregate fruits are created from several carpels that was from the same flowers. Strawberries and raspberries are examples of this type of fruit. Aggregate fruits are made from a compilation of flower blossoms. Many ovaries from a single flower would develop a fruit once they are merged.

Match the description to the part of bone.

Nikitich [7]

Answer:

strong, dense outer layer of a bone- compact bone

tissue in the hollow part of the bone- bone marrow

lightweight, inner layer of a bone that

contains many small spaces- spongy bone

Explanation:

Compact bone is also known as cortical bone and is a major property and source of skeletal frames in the body due to its strong, dense outer layer.

Bone marrow is the tissue in the hollow part of the bone. It is important as it helps in the production of blood cells

Spongy bone is also known as cancellous bone. It is the lightweight, inner layer of a bone that contains many small spaces which contains a high proportion of bone marrow.
