After Pedro had breakfast, he went for a run. Identify at least three energy transformations that had to take place to allow Pedro to complete his run. Then use evidence to support the claim that energy in this system was conserved as it was transformed.​

Answers

Answer 1
I tried my best to answer.

1) Chemical to mechanical (calories -> muscle contractions)
2) mechanical to mechanical (muscle -> motion)
3) mechanical to thermal (motion -> heat from the body causes sweating)

The potential energy is stored in the body chemically (via food). That potential energy is then released when the body is put in motion.
Answer 2

Answer:

When Pedro ate breakfast, he consumed chemical energy. Chemical energy is a form of potential energy and that potential energy was stored in his breakfast. When he went out for a run, the chemical energy transformed into mechanical energy, which is a form of kinetic energy. The mechanical energy then transforms into thermal energy when he is running. While running his temperature started to rise which caused him to sweat. The energy in his system was conserved as it was transformed because the energy was constant. When the energy was being transformed between different types, the total amount of energy remained the same.

The nucleolus is a region of the nucleus where ribosomal RNAs are synthesized.

Ribosomes are protein synthesis factories made from the ribosomal RNAs that are synthesized in the nucleolus and ribosomal proteins.

Sometimes, ribosomes are found free in the cytoplasm, other times they are attached to the endoplasmic reticulum, forming the rough endoplasmic reticulum. The rough endoplasmic reticulum is the site of protein synthesis for proteins that are to be secreted from the cell

A . Nucleic acids and carbohydrates

B . Nucleic acids and proteins

C . Lipids and nucleic acids

D. Proteins and lipids

Answers

Answer:

D

Explanation:

The two types of biomolecules being described in the scenario would be nucleic acids and proteins.

Nucleotides are the building blocks of nucleic acids. Each nucleic acid in the form of DNA or RNA has its nucleotide sequence.

DNA is responsible for the storage of genetic information. In order for genetic information to be expressed, the information in DNA is transcribed into RNA. The genetic codes in RNA are translated to their respective amino acids and linked together by peptide bonds as proteins. Thus, genetic information are usually expressed in proteins and the RNA serves as an intermediate molecule.

Answers

Answer:

D. Folding and breaking of sedimentary rocks and erosion.

The two basic geologic processes that contributes to the formation of folded mountain ranges are ; ( D ) Folding and breaking of sedimentary rocks and erosion

Folded mountains are formed by the collision of two or tectonic plates, the movement and collision is mostly caused by massive erosion.

Tectonic plates are formed by the breaking down of the earth's outermost layer into large rock slabs which lies on a molten layer of rock these large slabs are components/make up the  sedimentary rocks

Therefore the folding and breaking of sedimentary rocks caused by massive erosion leads to the formation of folded mountain ranges.

Hence we can conclude that The two basic geologic processes that contributes to the formation of folded mountain ranges are ; Folding and breaking of sedimentary rocks and erosion

Autosomal alleles are the genetic inheritance by the variants that are passed from parent to child. From the cross between B+Bb Ww × B+Bb Ww, 3/16 bearded, black coat, and 1/16 bearded, white is not a correct phenotype. Thus, options b and e are correct.

Autosomal recessive = B+ (beardless ), w (white coat)

Yy ´ yy
YY ´ yy
Yy ´ Yy
yy ´ yy

Answers

Answer:

Its the first one

Yy is yellow (dominant) and heterozygous

yy is green (recessive)

with Yy and yy, you could only get 50% Yy(yellow) and 50% yy(green).  There is no way to make only yy or YY, and in order to make 100% Yy you would need one yy and one Yy

The cross between parent plants if one is heterozygous and has yellow-colored pods and the other is homzygous and has green-colored pods -  Yy yy

Heterozygous genotype:The presence of two different alleles at a particular gene locus.A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles.Y for yellow and y for green then the heterozygous parent would be - Yy with yellow phenotype

Purebred genotype:

consists of gene pairs with genes that are the same allele typealso called the hozygousY for yellow and y for green then the hemzygous parent would be - yy with green phenotype

Thus, the cross would be -  Yy yy

The atmosphere exerts a force on earth. Why does yhe atmosphere exert pressure on earth?

Answers

Answer:

The atmospheric molecules have energy because they have a quantifiable temperature. It vibrates and circulates, and bumps into other gas molecules. Most of them are elastic, which means that the molecules bounce off more than they stick together. The "bump" is a strength. It becomes pressure when applied over an area, such as your skin or earth's surface.

Explanation:

How much is the pressure of the atmosphere?

Pressures are determined by height (mostly by the volume of water vapor), temperature, and weather. The average air pressure, however, is 14.7 pounds per square inch, 29.92, or 1.01 to 105 paschal in regular conditions at the marine level. At 5 km altitude, atmospheric pressure is just about 50%. (about 3.1 miles).

Why is the Earth's surface under pressure so much higher? It's because the weight of all the air at that location really is measured. There's not much air around you to press down while you are high in the atmosphere. The whole atmosphere is heaped above you on the surface of the Earth. While the gas molecules are extremely light and distant, they are many!

Describe the overall trend in corn yield from 1988 to 2008. How does the trend in corn yield during the time compare to tends for total nutrients and nitrogen?

Answers

The trend in the corn productivity shows an increase from the year 1988 to 2008.

This is because of high yielding varieties of corn, new technology and application of optimum dose of fertilizer and other agronomic activities. The trend in corn yield for the nutrients and nitrogen increases because new high yielding varieties needs more nitrogen as well as other nutrients as compared to local or old varieties so it is concluded that productivity and nutrients uptake increase with the passage of time.

The cell wall provides rigid support and protection for the cell.


The cell wall is a network of fibers inside the cell that gives the cell its shape.


The cell wall is a barrier that allows certain substances into and out of the cell.


The cell wall is a series of folded membranes that produces and distributes proteins in the cell.

Answers

the cell wall provides rigid support and protection for the cell

The cell wall is a layer outside the cell membrane and provides rigid support and protection to the cell. So, the correct option is A.

What is a cell wall?

A cell wall is a thick and rigid layer composed mainly of polysaccharides present outside of the cell membrane that protects the cell. A cell wall is a part of a cell but it is not a living component. Unlike the cell membrane, a cell wall is totally permeable in nature.

The cell wall of different kinds is present in plants, fungi and prokaryotes. Animal cells do not have a cell wall.

The cell wall in fungi is made up of a polysaccharide called chitin. This component is also present in the exoskeletons of arthropods.

The cell wall in the case of prokaryotes is made of a polysaccharide called peptidoglycan. Prokaryotes have 2 layers in their cell wall.

Plants contain cell walls made of cellulose. The plant cell wall has 3 layers. These are pectin, cellulose and hemicellulose. It also contains a small number of minerals.

The materials required for the formation of the cell wall are a special kind of polysaccharide called structural polysaccharides. The monomer for these polysaccharides is glucose.

Therefore, the correct option is A.
