Directions: Select each correct answer. More than one answer may be correct.Rodrigo is using the design process to make a device that will cool a drink without ice or electricity. His first prototype was simply an airtight, watertight pouch containing 40 g of ammonium chloride (NH4Cl). He added 100 mL of water to the ammonium chloride, sealed the pouch tightly, and then wrapped the pouch around a small bottle of water. He tested his prototype by measuring the temperature of the bottle of water over time. Next, Rodrigo performed the same test with different amounts and different concentrations of the ammonium chloride solution. For each set of measurements, he found the lowest temperature reached by the bottle of water and calculated the total temperature change. The table below summarizes his results. Maximum Cooling Achieved ___________________________________________ trial 1 2 3 4 5 6 7 ___________________________________________ grams of NH4Cl 30 40 50 50 60 70 80 ___________________________________________ amount (mL) of water added 100 100 100 150 150 200 200 ___________________________________________ greatest temperature change (–°C) 3.6 4.3 4.3 4.8 5.2 5.6 5.8 ___________________________________________ Finally, Rodrigo held the amount and concentration of the solution constant while trying different amounts of insulation.

Cell growth occurs in interphase or mitosis?

Answers

Cell growth occurs in interphase.

The cell cycle is composed of interphase, mitosis, and cytokinesis. It can be described in five steps.

The first three steps of the cell cycle are called the interphase. This is where the cell grows, the cell matures, and where the cell carries out its life function. The fourth step is mitosis and the fifth step is cytokinesis.

The interphase has three stages. These are Gap 1, synthesis, and Gap 2.

Gap 1 or growth 1 - where the cell grows and functions normally. Cell growth is twice its original size.

Synthesis - where cell duplicates its DNA

Gap 2 or growth 2 - where cell resumes its growth in preparation for division.

Prairie soils (mollisols) are _______.a.
poor in organic matter
b.
easy to cultivate and fertile
c.
poor in mineral nutrients
d.
difficult to cultivate but fertile

Answers

Correct answer: B). Easy to cultivate and fertile

The prairie is grassland soils that possess a dark colored surface and these soil are highly fertile in nature. These soils are rich in minerals like calcium and magnesium.

The dark color of soil comes from the added organic matter to the soil that comes from the roots of prairie plants. They are formed in the areas that are too dry to be forested, but too wet to be desert.

Hence, the correct answer would be option B.

Answer:

B: easy to cultivate and fertile

Explanation:

A _______ is a segment of a chromosome that codes for a specific protein.A: gene
B: crossed out
C: amino acid
D: nucleotide

Answers

In the sentence "A _______ is a segment of a chromosome that codes for a specific protein", the word that correctly completes the sentence is A: gene. In other words, a gene is a sequence of a chromosome that holds the code for protein synthesis. In the transcription, the gene is transcribed into messenger RNA (mRNA). In translation, mRNA is translated into proteins.
A _______ is a segment of a chromosome that codes for a specific protein.
A: gene

The hot and humid weather in Texas during the summer is most likely due to what type of air mass?

Answers

Answer:

Maritime tropical Pacific air mass

Explanation:

The Maritime tropical air masses are originated in the tropical oceans of both the hemispheres. It generally forms in the region between 15° to 35° latitude. It is denoted by (mT). In the northern hemisphere, the places that lie in this region are the northern Pacific ocean and the northern Atlantic. They are characterized by high temperatures and rich in moisture content (high humidity). This air mass during winter moves towards the land areas in the form of wind breeze affecting places like Mexico and Texas, that experiences hot and humid weather during the summer season.
Maritime tropical, or mT. This type of weather is from a source region in the tropics and over water

What does the respiratory system eliminate when there is an excess of hydrogen ions in the body?

Answers

Answer:by breaking down carbonic acid into carbon dioxide and water.

The carbon dioxide is expelled from the body

Explanation:the body is able to maintain a constant internal environment through hoemostatis.one of such control is the acid-base balance in the body.

It does this by regulating the amount of hydrogen ions in the blood.A low pH indicates an acidic condition and a high pH indicates an alkaline condition.

The human blood has a pH of 7.35---7.45.it is slightly alkaline and needs to keep this range constant.

The lungs and kidneys involved in regulating the body pH.

When there is excess hydrogen ion in the blood, bicarbonate ions combine with the hydrogen ions to form carbonic acid . this carbonic acid breaks down into water and CO2 .the co2 is expelled from lungs through gaseous exchange.

When the accumulation of acid in the blood is high,the pH drops below 7.35 and this is called respiratory acidosis.

When there is excess alkaline in the blood,the pH goes beyond 7.45 and this is called respiratory alkalosis.
