Solids are usually more dense than liquids. There are few cases where solids are less dense than liquids, one being water. This is why ice floats in water :)

Based on the role of ubiquitin in protein deconstruction as stated in the passage, the correct options are as follows:

to tag waste proteins for recycling in the proteasomes; option A.
Wastes will build up in vital organs, and the organism will experience disease; option D
the neurons affected by the ataxin-1 protein buildup are in a region of the brain that manages muscle control; option D.

<h3>What are phrases?</h3>

Phrases refers to a group of words which contains a verb but which on their own do not make complete sense.

In the description of the role of Ubiquitin, it is described as a small polypeptide chain containing 76 amino acids. The main tole of ubiquitin is to tag proteins for deconstruction in the proteasomes.

Therefore, the phrase describes the purpose of ubiquitin is to tag waste proteins for recycling in the proteasomes; option A.

Based on the passage, the statement that describes the overall consequence of proteins containing mutations is: Wastes will build up in vital organs, and the organism will experience disease; option D

Individuals with spinocerebellar ataxia experience loss of muscle control, even though the ataxin-1 protein builds up only in the brain and spinal cord because the neurons affected by the ataxin-1 protein buildup are in a region of the brain that manages muscle control; option D.

In conclusion, mutations in ubiquitin-tagged proteins will result in accumulation in the body since they cannot be deconstructed in the proteasomes.

Moderate alcohol consumption is no more than ________ alcoholic drink(s) daily for adult women and up to ________ drink(s) daily

liberstina [14]

Moderate alcohol consumption is no more than $One$ alcoholic drink(s) daily for adult women and up to $Two$ drink(s) daily for adult men.

What is an alcohol?

Alcohol is an organic compound containing a hydroxyl group and a carbon atom; Alcohol can be an intoxicant found in alcoholic beverages.

An alcoholic drink (also called an alcoholic beverage, adult beverage, or simply a drink) is a drink that contains ethanol, a type of alcohol that acts as a drug and is produced by fermentation of grains, fruits, or other sources of sugar.

The consumption of alcoholic drinks, often referred to as "drinking", plays an important social role in many cultures. Most countries have laws regulating the production, sale, and consumption of alcoholic beverages.

So, according to the scientific studies, the alcoholic consumption for women in a day is not more then one and for men is not for two drink(s)

1 Drink includes:

For beer: 355 ML

For Wine: 148 ML

Suppose an ice cube weighing 36.0 g at a temperature of 10°C is placed in 360 g water at a temperature of 20°C. Calculate the te

Scilla [17]

Answer:

10.44 °C

Explanation:

When the thermal equilibrium is reached, both of the substances have the same final temperature (T). The liquid water will lose heat, and the ice cube will absorb this heat. The temperature of the ice will increase until it reaches 0°C, at this temperature, it will change of phase for liquid, absorbing heat, but without a change in the temperature. Then the temperature will increase until the equilibrium.

By the energy conservation, the total amount of heat must be equal to 0:

Qice + Qmelting + Qliquid1 + Qliquid2 = 0

Liquid 1 is the ice after melting, and liquid 2 the liquid that was already at the flask. When there's a change of temperature:

Q = n*c*ΔT, where n is the number of moles, c is the heat capacity and ΔT is the temperature change (final - initial). The temperature variation in °C is equal in K, so the temperature may be used in °C.

The melting heat is:

Q = n*Hfus, Hfus = 6007 J/mol

The molar mass of the water is 18 g/mol, so the number of moles of the water and the ice are:

nwater = nliquid1 = 360/18 = 20 moles

nice = 36/18 = 2 moles

Qice + Qmelting + Qliquid1 + Qliquid2 = 0

2*38*(0 - (-10)) + 2*6007 + 2*75*(T - 0) + 20*75*(T - 20) = 0

760 + 12014 + 150T + 1500T - 30000 = 0

1650T = 17226

T = 10.44 °C
