Answer:

The waves erode seashells and rocks on the shore into small granuels called sand.

Explanation:

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of the diagram illustrating the growth chamber. However, since insects also produce/exhale carbon dioxide (CO₂) as a waste product, the level of CO₂ in the growth chamber will increase since insects will serve as an additional source for the production of CO₂.

This model shows how carbon is been cycled though the earth's systems. The CO₂ released/exhaled by animals is been inhaled by plants and used for the production of food substance like glucose (through the process of photosynthesis). Animals eat these plants and then release carbon from these food sources as CO₂ which is taken up from the environment again by plants.

Answer:

Density is the degree of consistency

Explanation:

volume x mass = density

Answer:

Density can be defined as the mass per unit volume of a substance.

Explanation:

Density is simply the mass per unit volume of a substance. When you are finding the density of the substance;

You first need to know the volume of a substance and the mass of that substance.

The S.I unit of density is;

Kg/m³ or Kgm³( Kilogram per cubic metre )

The correct answer is true.

Most oil and natural gas formed where forces within Earth are folded and tilted thick rock layers, and they are also formed with plankton in which is concealed with sediment (a natural & solid material that is fertile to enrich nutrients in soils).

I hope this helps you, have a great day. :)

Answer:

Procyon B's progenitor star most likely had around 2.59 solar masses. Estimates suggest that the star spent about 680 million years on the main-sequence, fusing hydrogen in its core. It evolved into a giant and lost much of its mass due to stellar winds

Heterotrophs/ or consumers

Explanation:

Heterotrophs, or consumers, are organisms that must obtain energy by consuming other organisms (autotrophs or other heterotrophs) as food.

Answer:

Typically, the nucleus is the most prominent organelle in a cell (Figure 1). The nucleus (plural = nuclei) houses the cell's DNA in the form of chromatin and directs the synthesis of ribosomes and proteins.

Explanation:

Nucleus is the potential organelle directs cellular activity and stores chromatin.

Nucleus is the most integral component, a double membraned cell organelle which carry all genetic material of the cell.

It regulates the growth and reproduction of the cell as it contain the genetic information.

It involve in duplication of DNA in the nucleus called as  DNA Replication by producing the copies of DNA .

It has a major role in cell division like mitosis and meiosis.

It is the site of transcription which produces different types of RNA from DNA.

A special site in the nucleus called the nucleolus a non-membrane-bound condensed region of chromatin involved in active ribosomal RNA synthesis.

Common knowledge

Answer:

D. Mesosphere

Explanation:

Answer: Rosalind Franklin discovered the density of DNA and, more importantly, established that the molecule existed in a helical conformation. Her work to make clearer X-ray patterns of DNA molecules laid the foundation for James Watson and Francis Crick's suggestion that DNA is a double-helix polymer in 1953.

Explanation:

Rosalind Franklin made numerous contributions to science in addition to helping to discover the structure of DNA, and in the field of virology, in coal-based materials, by using X-ray crystallography, in agriculture, etc.

She was one of the greatest scientists who made significant contributions to the field of DNA by using X-ray crystallography, and apart from that, she also made contributions to the field of virology. As X-ray diffraction facilitates the study of the structure of viruses such as the tobacco mosaic virus and the polio virus and helps in understanding the replication of viruses, it is also helpful in the study of the structure of coal and other carbon-based materials.

Hence, Rosalind Franklin made numerous contributions to science in addition to helping to discover the structure of DNA, and in the field of virology, in coal-based materials, by using X-ray crystallography, in agriculture, etc.

Answer:

glycolysis in the cytoplasm

Explanation:

~ Fermentation and cellular respiration are alike in that they both begin with a series of reactions known as glycolysis, which breaks glucose molecules into smaller pyruvate molecules. They are also similar in that during both processes, ATP is produced for the cell to use.

Answer:

f = 7.87×10¹⁴ Hz

Explanation:

Given data:

Speed of light = 3×10⁸ m/s

Wavelength of light = 3.81 ×10⁻⁷ m

Frequency of light = ?

Solution:

Formula:

Speed of wave = wavelength × frequency

Now we will put the values in formula.

3×10⁸ m/s = 3.81 ×10⁻⁷ m × f

f = 3×10⁸ m/s /  3.81 ×10⁻⁷ m

f = 0.787 ×10¹⁵ s⁻¹

   s⁻¹  = Hz

f =  0.787 ×10¹⁵ Hz

f = 7.87×10¹⁴ Hz

Explanation:

Answer:

Enzymes are not used up in a chemical reaction. Usually, the enzyme will “reset” and be ready to use in another reaction. This is due to the fact that enzymes are proteins, and their shape is what they use in a chemical reaction.

Explanation:

Enzymes serve a similar purpose for chemical reactions in an organism's body, which is to lower the amount of "activation energy" needed for a particular chemical reaction to occur. Without enzymes, many chemical reactions would occur at a much slower rate because the amount of activation energy required would be far greater.

Answer:

15 km/h

Explanation:

If it takes 30 minutes to run 7.5 km/h if you double the time to 60 minutes (an hour) 7.5 doubled is 15.

DNA is essentially a storage molecule. It contains all of the instructions a cell needs to sustain itself. These instructions are found within genes, which are sections of DNA made up of specific sequences of nucleotides. In order to be implemented, the instructions contained within genes must be expressed, or copied into a form that can be used by cells to produce the proteins needed to support life.

The instructions stored within DNA are read and processed by a cell in two steps: transcription and translation. Each of these steps is a separate biochemical process involving multiple molecules. During transcription, a portion of the cell's DNA serves as a template for creation of an RNA molecule. (RNA, or ribonucleic acid, is chemically similar to DNA, except for three main differences described later on in this concept page.) In some cases, the newly created RNA molecule is itself a finished product, and it serves an important function within the cell. In other cases, the RNA molecule carries messages from the DNA to other parts of the cell for processing. Most often, this information is used to manufacture proteins. The specific type of RNA that carries the information stored in DNA to other areas of the cell is called messenger RNA, or mRNA.

How does transcription proceed?

Transcription begins when an enzyme called RNA polymerase attaches to the DNA template strand and begins assembling a new chain of nucleotides to produce a complementary RNA strand. There are multiple types of types of RNA. In eukaryotes, there are multiple types of RNA polymerase which make the various types of RNA. In prokaryotes, a single RNA polymerase makes all types of RNA. Generally speaking, polymerases are large enzymes that work together with a number of other specialized cell proteins. These cell proteins, called transcription factors, help determine which DNA sequences should be transcribed and precisely when the transcription process should occur.
