A 1500 kg car sits on top of a car carrier truck 2.5 meters above the ground how much potential energy does the car have
Answer:
36,787.5 Joules
Explanation:
Potential Energy = mass * acceleration due to gravity * height
U = mgh
We know the following:
mass = m = 1,500 kg
acceleration due to gravity = g = 9.81 m/[tex]s^{2}[/tex]
height = h = 2.5 m
When we substitute each value into the formula we get the following:
U = 1,500 kg * 9.81 m/[tex]s^{2}[/tex] * 2.5 m = 36787.5 kg[tex]\frac{m^{2}}{s^{2} }[/tex] = 36,787.5 Joules

Human red blood cells can live from two to four months without a nucleus, and yet they continue to synthesize hemoglobin. This Group of answer choices is a chemical process that does not require continued living pathways; the red blood cells are essentially dead after they lose their nuclei. suggests that there is a low level of RNA polymeraseto degrade the mRNA. means that the necessary ribonucleases are continually translating DNA. means that both the necessary mRNAs must persist and there must be a low level of RNA-degrading enzymes present.
Answer:
means that both the necessary mRNAs must persist and there must be a low level of RNA-degrading enzymes present
Explanation:
Mature red blood cells (also known as erythrocytes) don't contain nuclei. The red blood cells that enter the bloodstream eject their nuclei in order to have more space for transporting hemoglobin, a protein whose main function is to bind molecular oxygen. Erythrocytes have a life span period of three (3) to four (4) months. During this period, the mRNA of the hemoglobin genes must remain intact in order to synthesize hemoglobin proteins (i.e., their subunits). Moreover, in mature red blood cells, the levels of the enzymes involved in the degradation of cytoplasmic mRNA (ribonucleases) must also be low to avoid bulk mRNA degradation.

C. chromatin and interphase
d. centromere and mitosis

Explanation:
But if you can describe the picture I can answer it
The nucleus is the major and the central organ of the cell. The structure inside of the nucleus is chromatin and the phase is interphase.
What is chromatin and interphase?Chromatin is a complex structure present only in the eukaryotic cells that are composed of protein and DNA. It is required for the packaging of the long DNA threads into a compact and dense form.
Chromatin makes up the chromosome and is the packaging element of the genetic material. The basic and smallest unit of the chromatin is the nucleosome.
Interphase is one of the cell cycle periods that contain the non-dividing phase. The G1, S and the G2 phase of the cell cycle are part of the interphases.
In this phase, the cell undergoes the process of replication or duplication and cell growth. Not the actual division of the cell occurs instead it prepares the cell for the division.
Therefore, option c. interphase and chromatin are the phases and the structures present inside the nucleus.

- Which occurrence is the result of the cell cycle in unicellular organisms?
A. cell repair
B. cell growth
C. cell replacement
D. cell reproduction
Answer:
D
Explanation:
Cell reproduction is the result of the cell cycle in unicellular organisms. The correct option is D.
What is cell reproduction?Cells split to produce multiple cells with similar, if not identical, contents. This process is known as cellular reproduction.
Nuclear division during mitosis produces two somatic cells that are genetically identical to the parent cell and have the same genetic complement.
Asexual reproduction in prokaryotes takes the form of cell division in unicellular organisms.
When an organism splits in half, it creates two totally distinct daughter cells, a process known as binary fission. The daughter cells are identical to the parent cells genetically.
Most of the time, Paramecium reproduces asexually via budding, however in poor circumstances, they produce sexually.
Unicellular organisms have a variety of asexual reproduction strategies, including multiple fission, fragmentation, and budding.
Thus, the correct option is D.

I NEED HELP PLZ ITS DUE TODAY. The sun produces a great amount of energy with sound and lights. We enjoy the sun's light and heat waves on Earth, but cannot hear any sound of the sun. Explain this phenomenon in terms of mechanical waves and electromagnetic waves. (10 Points)
Answer:
See explanation
Explanation:
First of all, we have to know the difference between a mechanical wave and an electromagnetic wave.
A mechanical wave requires a material medium for propagation. It does not travel through space. An electromagnetic wave does not require a material medium for propagation and it can travel through space.
Light and heat are electromagnetic waves. They both belong to the electromagnetic spectrum. On the other hand, sound is a mechanical wave.
While heat and light can travel through space, sound can not because it is a mechanical wave. Sound has to pass through gas molecules and there is no gas in outer space.
Hence, we enjoy the sun's light and heat waves on Earth, but cannot hear any sound of the sun.

Which of the following statements about metabolism are true? 1) Catabolism is the process in which complex substances are broken down, yielding a net output of energy. 2) Metabolism is an integrated system in which many of the same reactions participate in degradative (catabolic) and biosynthetic (anabolic) pathways. 3) Anabolism involves the synthesis of polymeric biomolecules and complex lipids from monomers such as fatty acids and nucleotides. 4) All organisms require an external source of energy, such as glucose or sunlight, for metabolic energy.
Answer:
the answer is 1), 2) and 3)
Explanation:
Metabolism can be defined as all the chemical reactions inside a cell that are required to carry out cellular functions (e.g., reproduction, growth, development). The metabolic reactions can be divided into anabolic and catabolic reactions. Anabolic reactions refer to metabolic reactions that require energy in order to construct new molecules from smaller ones (i..e., biosynthesis). Anabolism comprises endergonic metabolic pathways which are fueled by the use of energy (e.g., cellular ATP). On the other hand, catabolic reactions refer to metabolic reactions where larger molecules are separated to form smaller ones. Catabolic reactions are exergonic because they do not require energy (for example, reactions involved in cellular respiration).

Explanation:
Quantity, information content, packing and replication of chromosome are the major differences that is present between the organization of DNA in viruses and bacteria as compared to eukaryotes. The quantity of DNA in bacteria and virus is less than eukaryotes. In virus and bacteria, DNA is arranged into a single circular chromosome while on the other hand, in eukaryotes, DNA is arranged into several linear chromosomes.
