Why does cell size need to be limited?

Where does the DNA come from that is in the parent cell?

Answers

Answer 1

Answer:

Your genome is inherited from your parents, half from your mother and half from your father. The gametes are formed during a process called meiosis. Like your genome, each gamete is unique, which explains why siblings from the same parents do not look the same.

The need to be able to pass nutrients and gases into and out of the cell sets a limit on how big cells can be. The larger a cell gets, the more difficult it is for nutrients and gases to move in and out of the cell. As a cell grows, its volume increases more quickly than its surface area.

Answers

Answer:

10m/s

Explanation:

Given parameters:

Frequency of wave  = 2Hz

Wavelength = 5m

Unknown:

Speed of the wave  = ?

Solution:

The speed of a wave is derived from the product of wavelength and frequency;

     speed  = frequency x wavelength

Insert the parameters and solve;

    speed  =2 x 5 = 10m/s

A student collects a sample of water from a pond near her home. She
examines a drop of the water under a microscope and sees four very
differently shaped single-celled organisms. Which of the following
can she reasonably conclude as the reason the organisms look so
different?

Answers

Answer:

A. Each organism had a different parent that passed on a set of unique genetic instructions.

Explanation:

Organisms can either be single-celled or multicellular. According to this question, a student collects a sample of water from a pond near her home. She then examines a drop of the water under a microscope and noticed it contains four very differently shaped single-celled organisms.

The single-celled organisms are of different shapes because they are from different parents, which passed on a set of unique genetic instructions via their genes to them. Organisms of the same species from the same parent will possess the same shape because they contain same gene which makes them look and behave similar.

However, in this case, the four different shaped single-celled organisms are of DIFFERENT SPECIES and hence, contain individual unique genes that makes them so

Fecal coliform is an indicator of what type of disease?

Answers

Answer:

Explanation:

Some waterborne pathogenic diseases include typhoid fever, viral and bacterial gastroenteritis and hepatitis A. The presence of fecal contamination is an indicator that a potential health risk exists for individuals exposed to this water.

Answer:

Thermotolerant coliform bacteria (commonly referred as fecal coliforms) are the group most frequently used as indicators of fecal pollution because they behave in a similar way to most pathogenic bacteria in the environment, and, during treatment, they are abundant and easy to determine.

What is cellular respiration ?

A series of chemical reactions known as cellular respiration break down glucose into ATP, which can be used as energy to power numerous body processes. Cellular respiration has three main stages: the citric acid cycle, glycolysis, and oxidative phosphorylation. The citric acid cycle takes place in the mitochondrial matrix, glycolysis takes place in the cytosol, and oxidative phosphorylation takes place on the inner mitochondrial membrane. Glucose, ATP, and NAD+ are the cellular respiration starting reactants, the rate-determining enzymes for cellular respiration are phosphofructokinase-1, pyruvate dehydrogenase, and isocitrate dehydrogenase, and the final products include ATP and water. One or more enzymes involved in cellular respiration, like succinyl-CoA-synthase or pyruvate kinase, are typically disrupted by diseases that affect this process.Glycolysis is the only process that can take place without oxygen, and only two ATP molecules can be produced for each glucose molecule. ATP and H2O are the two final end products of cellular respiration. Glycolysis produces two pyruvate molecules, four ATPs (a net of two ATP), two NADH molecules, and two H2O molecules.One acetyl-CoA, one NADH, and one CO2 are produced for each pyruvate molecule when oxygen is present. One GTP, three NADH, one FADH2, and two CO2 are the products of the TCA cycle. GTP is an energy-rich compound similar to ATP that is typically used in environments with lower pH. The electron transport chain can then use NADH and FADH2 to make more ATP as part of oxidative phosphorylation.

How does deforestation affect coral reefs?

Answers

The world's coral reefs are being damaged by harmful runoff, which new research shows is being caused by the clearing of forests. Preventing soil erosion may help protect the reefs, which shield coastlines from ocean waves, draw tourists with their brilliant colors and provide a habitat for fish.

For centuries, humans around the world have been clearing away forests to make room for livestock, farming, and other uses. Scientists say that when the forest cover is lost, soil washes away into rivers that flow into the oceans and, they believe, onto coral reefs.

That runoff adds nutrients to the ocean water. It's essentially too much of a good thing, and scientists have long suspected it can kill the coral. Runoff also clouds the water, blocking light from reaching the reef.

Answer: When the forest cover is lost, soil washes away into rivers that flow into the oceans and, they believe, onto coral reefs. That runoff adds nutrients to the ocean water.

Explanation: Basically, when this occurs, the roots are no longer attached to the soil, letting all the nutrients get ruined in the ocean water instead of feeding plants/animals/trees.

What is a nucleotide base?

A nucleotide is the monomer constituting DNA or RNA biopolymer molecules.

Each nucleotide consists of a nitrogenous heterocyclic base (or nucleobase), which can be either a double-ringed purine or a single-ringed pyrimidine; a five-carbon pentose sugar (deoxyribose in DNA or ribose in RNA); and a phosphate group.

The two classes of nitrogenous bases are purines and pyrimidines and they are as follows;

Purines - Adenine and GuaninePyrimidines - Cytosine, Uracil, Thymine

How would you demonstrate that all cells come from preexisting cells

Answers

Answer: The generally accepted parts of modern cell theory include: ... All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms. The activity of an organism depends on the total activity of independent cells.

Explanation:

To demonstrate that all cells come from pre-existing cells, you should: Observe a bacterium performing binary fission to form clones of itself.

A cell can be defined as the basic functional, structural and smallest unit of life which is found in all living organisms.

According to cell theory, the following statements are true about cells;

All living organisms comprises small structural units called cells.A cell is the fundamental (basic), functional unit of life.Every living organism is made up of one or more cells: unicellular or multicellular.All cells are produced from existing (other) cells i.e pre-existing cells produce new ones through a process called cell division.

Binary fission is an asexual reproduction wherein the body of a prokaryotic organism such as bacterium, is divided into two (2) new identical bodies.

In order to demonstrate that all cells come from pre-existing cells, you should observe a bacterium performing binary fission (dividing) to form clones of itself.

In conclusion, the chromosome (pre-existing cell) of a bacterium containing deoxyribonucleic acid (DNA) and associated proteins replicates and then divides in half to form clones of itself (identical daughter cells).

What is cell?All living organisms are made up of cells, which are the basic building components. There are billions of cells in the human body. They support the body's structure, absorb nutrients from meals, transform those nutrients to energy, and perform specific activities. Cells also carry the body's genetic material and have the ability to replicate themselves.A cell is a cytoplasmic mass that is outwardly bound by a cell membrane. Cells are the smallest structural units of living matter and make up all living things. They are usually tiny in size. Most cells have one or more nuclei, as well as additional organelles that perform various functions.In unicellular and multicellular organisms, cells act differently. A unicellular creature relies on only one cell to conduct all of its duties. A multicellular organism contains cells that specialize in distinct roles and work together to maintain the organism.
