The salt concentration in a cell's cytoplasm is 0.9%. The cell is placed in a 10% salt solution. Which term best describes the 1
fenix001 [56]

The term that best describes the 10% salt solution relative to the cytoplasm of the cell is ' Hypertonic'

Explanation:

When the concentration of two solutionare compared they can be described as hypertonic, hypotonic or isotonic with relation to one another.

When two solutions have same concentration and osmotic pressure they are said to be isotonic solutions.

The solution which has higher molecular concentration and higher osmotic pressure than the other solution is called hypertonic solution.

The solution which has lower molecular concentration and lower osmotic pressure with respect to other solution is called hypotonic solution.

Here the solution of salt has a higher concentration than cell sap so it is a hypertonic.

Can the use of badger control (including culling) be justified in the
bonufazy [111]

Answer:

no. badger vaccination is better

Explanation:

spreading mostly happens cattle to cattle

"killing badgers will not solve the problem. Badgers are not the primary cause of the spread of bTB in cattle: the primary route of infection is cattle-to-cattle contact[2]. The Government's badger cull is flying in the face of science. It should be putting more resources into speeding up the development of an effective cattle vaccine, amongst other measures"

Which pattern of inheritance results from individual organisms having many different genes working at the same time to control a
saw5 [17]
The answer is polygenic inheritance.
Many physical characters (traits) depend on many different factors, each of which is determined by different genes. This is called polygenic inheritance.


For example, the color of the skin in humans. The color of the skin results from the interactions of several factors determined by different pairs of genes:-Certain genes could affect the metabolism of skin melanocytes.-Other genes can determine the distribution of melanin in the thickness of the skin.-Some genes could determine the relative amounts of each of the two possible types of melanin.-Others may affect the production of certain hormones involved in the activity of melanocytes.

I just need help understanding the question a bit more
mash [69]

Answer:

D

Explanation:

So basically genes are made of DNA molecules. DNA molecules are the building blocks of genes.... if you think about legos for a second the building blocks of legos would be plastic right? because without plastic you don't have legos which is same here... genes are legos and DNA molecules are the plastic that make them (if you get my analogy).

So genes are the information carriers because they carry information on how to make a certain protein or express certain characteristics. Gene directs the cell to make certain proteins and proteins are the key players that are involved in many cellular process because they carry out major functions hence, the protein determine the function of cell because without protein the cell would have no function

The stethoscope is a device commonly used by doctors to monitor heart function. When listening to a heart beating using a stetho
Effectus [21]

Answer:

The correct answers are:

1. closing

2. the ventricles and arteries,

3. a constricted trachea

Lub is the first sound of a heartbeat and is mentioned as S1. It is usually produced due to the closing of tricuspid and and mitral or bicuspid valves present between atria and ventricles.

Tricupsid is located between atrium and ventricle of the right hand side and mitral valve is located between atrium and ventricle of the left hand side. They prevent the back flow of blood from ventricles to their respective atria.

Dub, being the second sound is written as S2. It is produced due to the closing of pulmonary (located between right ventricle and pulmonary artery) and aortic valves (located between left artery and aorta).

These valves prevent the back flow of blood from arteries into the ventricles.

The time between the two sounds is often taken as the measure of the diastole i.e. ventricular filling.

Wheezing refers to a high-pitched sound produced when a person breathes, especially during exhale. It is caused by constriction of the airways or inflammation. It is considered as a symptom of various diseases such as asthma, COPD, allergies, bronchitis etc.
