does aerobic and anaerobic respiration have the same number of carbons, hydrogens and oxygens? Explain.

Answers

The fundamental difference between aerobic and anaerobic respiration is the usage of oxygen in the process of cellular respiration. Aerobic respiration, as the name suggests, is the process of producing the energy required by cells using oxygen. The by-product of this process produces carbon dioxide along with ATP – the energy currency of the cells. Anaerobic respiration is similar to aerobic respiration.

Photosynthesis uses energy from the Sun to make sugars such as glucose. What has to happen to the glucose before it can be used by plant cells?


A The glucose combines with another sugar to make usable energy.
B The glucose combines with oxygen to make usable energy.
OC The glucose combines with carbon dioxide to make usable energy.
OD Nothing has to happen to the glucose. Plant cells can use it as is.

Answers

Answer:

Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy. This energy is used to fuel growth and all of the normal cellular functions.

D Nothing has to happen to the glucose. Plant cells can use it as is.

What happens to the glucose produced by plants?

Glucose produced by photosynthesis is a simple sugar that is used by plant cells as a source of energy and as a building block for other organic compounds. The glucose can be transported within the plant and used directly by cells as a source of energy through cellular respiration.

In cellular respiration, glucose is combined with oxygen to release energy in the form of ATP (adenosine triphosphate), which is used to fuel various cellular processes. So, there is no need for glucose to undergo any additional chemical reactions before it can be used by plant cells.

Answer:

B. Chromosomes are threadlike structures that carry genetic information

Explanation:

Normally developed humans carry about 46 chromosomes in each cell, so A is false.

The numver of chromosomes is equal from the mother and the father, so C is false.

Chromosomes are arranged in 23 distinct pairs, so D is false.

The statement that best describes chromosomes is: Chromosomes are the threadlike structures that carry the genetic information.

What is a chromosome?

It is a structure that is present in both prokaryotes and eukaryotes and is composed of nucleic acid (DNA) and proteins. It is responsible for genetic information.

Facts about chromosomes:Humans have 46 chromosomes in all somatic cells, and the reproductive cells except in the sperm and ova, which are haploid  with 23 chromosomes only. Humans receive one set of 23 chromosomes from their mother and the other set from their father.Chromosomes are arranged in 23 distinct pairs in the human body.

All of the following are characteristics of proteins EXCEPT:
A They contain genetic information
B They can catalyze chemical reactions.
c They can transport materials.
D They can repair tissues.​

Answers

Answer: A.

Explanation: Proteins are made by decoding genetic information carried by DNA, but contain no genetic information themselves. Although the sequence of amino-acids in a protein matches the code in DNA, there is no process for using protein as a template for DNA.

Proteins may be structural, like collagen in tendons or keratin in hair and fingernails, or enzymes active in metabolism, or in transport, such as haemoglobin that transports oxygen, or in transporting ions into and out of cells against a concentration gradient.

Answer:

the answer is protons

Explanation: Atoms of each element contain a characteristic number of protons. In fact, the number of protons determines what atom we are looking at (e.g., all atoms with six protons are carbon atoms); the number of protons in an atom is called the atomic number. In contrast, the number of neutrons for a given element can vary.

Certain cells, such as those along the digestive tract, need to absorb a lot of materials. What unique features do you notice about the shape of these cells? How might this improve their ability to absorb materials?

Answers

Answer:

Microvilli are typical of these cells. These projections increase the absorptive area on the cell surface.

Explanation:

Epithelial cell surfaces show different structure shapes that allow the cells to adapt to and accomplish their functions. Most of these structures are related to the absorption surface and the need to move substances.

The development of microvilli is very common in epithelial cells. These are folds or finger-like projections emerging from the apical surface of the cell. Their principal function is to absorb. The microvilli of the intestinal epithelium are very uniform in size and distribution.

Which of these is the direct result of an error in the transcription of a DNA nucleotide
Amino acids do not bond to tRNA.
The nuclear membrane is ruptured.
A codon sequence is incorrect.
Transportation of mRNA does not occur.

Answers

The direct result of an error in the transcription of a DNA nucleotide is that a codon sequence will be incorrect. So the correct option is C.

What is transcription?

The first step in the expression of a genetic code is called transcription. During gene expression, the information stored in the DNA is expressed in the form of proteins.

In transcription, DNA is utilized to produce RNA. The RNA molecule is the copy of the DNA's genetic sequence. The RNA copy produced by the process of transcription is called an RNA transcript.

This transcript has the required information for the construction of a polypeptide chain. But before the formation of proteins, a eukaryotic RNA transcript requires processing to be converted into mRNA.

The mRNA thus produced has codons for the formation of proteins. Each amino acid is a result of the translation of three codons.

Therefore, if there is an error in the transcription of DNA nucleotides, the codon sequence will be incorrect. The correct option is C.

The Devils Hole pupfish is one of the world's rarest fishes, spending most of its life in the top few meters of very warm waters of a cavern located in the middle of the Mojave Desert. Devils Hole,
a geologic pool, is the only naturally occurring habitat for the endangered Devils Hole pupfish. This fish's habitat is one of the smallest natural ranges known for any vertebrate. Devils Hole is an
extreme environment, with water temperatures and dissolved oxygen concentrations near the lethal limits for most fish species.
Which of the following statements best explains why the Devils Hole pupfish are able to live in this environment?

Answers

Answer:

Thermal invasive

Explanation:

Devils Hole pupfish can live in this environment because they have adapted genes, which offer resistance to their bodies to the harsh environment where they live.

We can come to this answer because:

A living being can only live in an inhospitable environment if its organism allows for an adaptation.In this case, we can say that Devils Hole pupfish had a population with different genetic compositions, where some had genes adapted to this environment and others did not have these genes.Devils Hole pupfish that didn't have the adapted genes didn't resist the environment and died.The Devils Hole pupfish that possessed the genes survived and passed those genes on to their descendants.

In this case, Devils Hole pupfish that received the genes adapted to the environment developed resistance that allows them to live amidst extreme resources.

The components that make up the genetic code are common to all organisms. If a segment of a gene contains 27 nucleotides, none of which are stop or starts codons, how many amino acids does this segment code for?

Answers

Answer:

9 amino acids

Explanation:

A segment of a gene that has 27 nucleotides will code for 9 amino acids.

Each codon on the gene potentially represents an amino acid and a codon is made up of 3 nucleotides each. Hence, in order to find out the total number of amino acids that a gene segment with 27 nucleotides can code for, the number of nucleotides should be divided by 3.

    number of amino acids = number of nucleotides/3

                     27/3 = 9 codons/amino acids
