Answer: Genes are transcribed into RNA molecules, which are then translated into proteins.

Explanation: Genes are sections of DNA that contribute to certain traits, characteristics or functions. Genes code for proteins or parts of proteins that influence things like the immune system, skin pigmentation, hormone production, and eye color.

Answer:

Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes.

Answer:

answer to question 37 is false.

Explanation:

Efficiencies may not exceed 100%, a good example is a perpetual motion machine(machine with moving parts). However, other effectiveness measures that can exceed 1.0 are used for heat pumps and other devices that move heat rather than convert it.

In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.

Maybe they might use that math thing for Science.

We divide our energy use among four economic sectors: residential, commercial, transportation, and industrial. Heating and cooling our homes, lighting office buildings, driving cars and moving freight, and manufacturing the products we rely on in our daily lives are all functions that require energy.

Explanation:

Hope this helps :\

A renewable resource is a substance of economic value which can be replenished or replaced either through natural recurring processes or biological reproduction.

This happens due to the renewable energy. Now let us understand the renewable energy are those energy that can be used again and again and it re-new after a short period of time. it is generally defined as that kind of energy resources that can be renewed naturally.

Renewable sources of energy can replace conventional sources of energy which produce harmful gasses which is harmful as well as costly.

We divide this energy in few sectors like: residential, commercial, transportation, and industrial. People use these resources for many different things which are used daily.

One of the major resource is the UV rays and people use it to produce the electricity. Many of such resources are also used in different chores like cooking, driving vehicles, etc.

Example: biomass is a biological material taken from plants or plant-based materials.

Biomass is considered a renewable resource because plants and plant-based materials can be found everywhere and once used these plants will continue to grow and supply the demand for biomass consumption.

Therefore, these resources are the most useful resources which can be renewed easily and thus used in different ways.

The print fossil, original-remains fossil, petrified fossil, carbonized fossil, landform, igneous, metamorphic, sedimentary, cleavage, and geology are the respective matches as given in the question.

Print fossil is imprint of plant or animal and basically known as fossil impression. Original-remains fossil comprises of the original tissues and parts of  organism and undecayed plant or animal part. Petrified fossil is replaced by a mineral. Carbonized fossil is only carbon remains. Landform is a mountain. Igneous is from magma.

Metamorphic is from physical and chemical changes. Sedimentary rocks are sandstone. Cleavage helps to identify rocks. Geology is the study of science of earth.

Answer: D and it should be C or A I'm second guessing-

Explanation:

Because the Earth is round, the frigid polar regions never get a high sun, and because of the tilted axis of rotation, these areas receive no sun at all during part of the year. The Earth revolves around the sun in an elliptical orbit and is closer to the sun during part of the year. When the sun is nearer the Earth, the Earth's surface receives a little more solar energy. The Earth is nearer the sun when it is summer in the southern hemisphere and winter in the northern hemisphere.

Earth is described as an open system and due to gravity matter cannot move freely and the correct options are option B and D.

Earth can be described as an open system due to its interactions with its surroundings. It receives solar radiation from the sun, which provides energy to sustain various processes on Earth. This energy drives the Earth's climate, weather patterns, and the cycling of substances such as water, carbon, and nutrients. However, Earth is not a closed system because it exchanges matter with its surroundings.

For example, it gains meteorites and cosmic dust from space and loses gases, such as hydrogen and helium, from its upper atmosphere.

Additionally, Earth's gravity holds its atmosphere and prevents the escape of gases and most solid materials into space. Thus, Earth's system is characterized by the exchange of energy and matter within the constraints of gravity.

To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.
