mention for comparisons among taxis,nastism and tropic ​

Answers

Answer 1

Tropism is the term used to describe the directional movement of plants, whereas taxis is used to describe the directional movements of animals in reaction to a stimulus.

What exactly is nastism?

Nastisms, also known as nastic motions, are typically found in plants and are non-directional reactions to stimuli (such as temperature, humidity, and light irradiance). Movement in plants can be caused by changes in turgor or growth, hence K+ ion concentration often regulates such movement in plants.

What distinctions exist between tropism and taxis?

Tropism is defined as the directional movement of plants, whereas taxis is defined as the directional movement of animals in response to a stimulus. The most prevalent taxi types are chemotaxis and phototaxis, which react to light (in response to chemicals).

You do a serial dilution in the same manner as the one in the video. A plate with a sample volume of 10-6 mL produced 43 colonies. What was the original cell density (CFU)?

Answers

Answer: 43 x 10^6  CFU.

Explanation:

Plate count is a method used to determine the number of viable microorganisms in a sample. When the bacterial concentration is high, serial dilutions are carried out in a 1:10 sequence. Then, the dilutions are successive dilutions keeping the dilution factor constant at each step. Small aliquots of these dilutions are seeded in medium contained in a Petri dish where the bacteria grow forming colonies. Then the plates are incubated and colonies develop both within the agar and on the surface.

If the concentration of the seeded aliquot is too high, the bacteria will grow too much and it will not be possible to distinguish the colonies. However, if the concentration is very low, the number of colony forming units (CFU) may be very low and thus can be counted.

Colony forming units are calculated:

CFU = Number of colonies / (volume seeded on the plate * dilution).

The dilution is 10^-6, the number of colonies counted is 43, and usually the volume plated is 0.1 mL, so we replace that in the equation:

CFU= 43 / (0.1 mL * 10^-6)

CFU= 43000000 = 43 x 10^6

Answers

Answer:

They typically have a tough, spiny surface, which inspired their name (in Greek, echinos means “spiny” and derma means “skin”). They also have the unusual ability to regrow lost body parts, and sea stars and brittle stars can regrow arms if broken off or eaten

Explanation:

Sea stars and brittle stars both use tube feet to catch prey. Therefore, option C is correct.

What are sea stars and brittle stars?

Echinoderms with a star form that belongs to the class Asteroidea are known as starfish or sea stars. These terms are frequently used incorrectly to refer to ophiuroids, which are properly called brittle stars or basket stars in common usage. Due to their membership in the class Asteroidea, starfish are also referred to as asteroids.

The benthic (bottom-feeding) fauna of the maritime environment includes brittle stars. They belong to the Phylum Echinodermata, which includes marine organisms with radial symmetry, five components, and frequent spines. They are commonly referred to as echinoderms.

Sea stars and brittle stars both use tube feet to catch prey. Therefore, option C is correct.

Find 2 ways that natural gas forms. List the steps of the two carbon pathways below. Label each location with A for atmosphere, B for the biosphere, G for geosphere, or H for hydrosphere. Use P for the anthroposphere.

Answers

Answer:

Biogenic and thermogenic

Explanation:

Biogenic and thermogenic are the two ways or mechanism that is responsible for formation of natural gas. Biogenic gas is formed with the help of methanogenic organisms that is present in marshes, bogs, landfills, and shallow sediments. Thermogenic gas is formed from organic matter that is buried in the deeper earth where the temperature and pressure are very high.

The organic pathway of the carbon cycle is the pathway in which carbon moves from atmosphere, through producers, herbivores and other organisms in the ecosystems, and converted back to the atmosphere.

In geological pathway, carbon moves from the atmosphere, through the ocean to rocks and the mantle, and then back to the atmosphere.

Answers

Velocity is the variable which is changing during motion of skater.

Impact of velocity on energy

Velocity is the variable which is changing when the skater moves up and down the track because moving upward on the slope decrease the speed of the skater while on the other hand, velocity increases when moving downward on the slope.

Mass of the body which is skating remain constant or can't change with height. Mass is the amount of matter present inside the body so we can conclude that velocity is the variable which is changing during motion of skater.

what do the arguments for and against the use of stem cells in medical research share?​

Answers

Answer:   Stem cell research can potentially help treat a range of medical problems. It could lead humanity closer to better treatment and possibly cure a number of diseases:

Parkinson’s Disease

Alzheimer’s Disease

Heart Diseases, Stroke and Diabetes (Type 1)

Birth Defects

Spinal Cord Injuries

Replace or Repair Damaged Organs

Reduced Risk of Transplantation (You could possibly get a copy of your own heart in a heart-transplantation in the future

Stem cells may play a major role in cancer

Better treatment of these diseases could also give significant social benefits for individuals and economic gains for society

Cons

"We should not mess with human life."

"Humans should not be trying to play God"

Some argue that stem cell research in the far future can lead to knowledge on how to clone humans. It is hard to say whether this is true, but we have seen devastating consequences of other research-programs, even with good intentions, such as nuclear research.

Stem cells are cells, which have the ability to transform into many different types of cells. The stems cells have the potential to specialize in any type.

The stem cells are extensively used for research, curing diseases, and especially in developing prosthetics. The stems cells provide new cells for the growth and development of the replaced and damaged cells.

The arguments for and against the use of stem cells are:

Arguments for the use of stem cells in medical research are:

1. The stem cells enhance the growth and development of healthy skin tissue.

2. The cells can be used to enhance the production of collagen.

3. The study of stem cells helps in understanding the causes of disease.

Arguments against the use of stem cells in medical research are:

1. The use of stem cells for research harms human life and dignity.

2. People believe that killing blastocysts or stem cells is equal to taking a human life.

3. However, the transplant of stem cells can be rejected by the patient's body, therefore, can cost the life of the patient.

Therefore, the use of stem cells for research can be fruitful or disadvantageous.
