How do you think genomics and genetic engineering will contribute to the development of more productive food crops and what ecological implications should be considered? Be sure to include examples of existing and future GMOs that are contributing to the debate. What are the main criticisms of the Green revolution, and how can we mitigate some of the negative aspects? Cite your work

Answers

Answer:

The importance of optimal nutrition for human health and development is well recognised. Adverse environmental conditions, such as drought, flooding, extreme heat and so on, affect crop yields more than pests and diseases. Thus, a major goal of plant scientists is to find ways to maintain high productivity under stress as well as developing crops with enhanced nutritional value. Genetically-modified (GM) crops can prove to be powerful complements to those produced by conventional methods for meeting the worldwide demand for quality foods. Crops developed by genetic engineering can not only be used to enhance yields and nutritional quality but also for increased tolerance to various biotic and abiotic stresses. Although there have been some expressions of concern about biosafety and health hazards associated with GM crops, there is no reason to hesitate in consuming genetically-engineered food crops that have been thoughtfully developed and carefully tested. Integration of modern biotechnology, with conventional agricultural practices in a sustainable manner, can fulfil the goal of attaining food security for present as well as future generations.

The solutions in the two arms of a U-tube are separated by a membrane that is permeable to water and glucose but not to sucrose. Side A is filled with a solution of 4M sucrose and 2M glucose. Side B is filled with 2M sucrose and 3M glucose. Initially, the solution in side A, with respect to side B is______________.

Answers

Answer:

hypertonic

Explanation:

The solution in side A is hypertonic with respect to side B.

A hypertonic solution is a solution with a higher concentration of solutes in comparison with a neighbouring solution separated by a selectively permeable membrane.

In terms of both sucrose and glucose concentrations, the solution in side A is higher than the solution in side B of the U-tube. Hence, side A is hypertonic to side B.

A hypertonic solution is as opposed to a hypotonic solution with the latter having a lower concentration of solutes as compared to a neighbouring solution. Isotonic solutions have equal solute concentrations with their neighbouring solutions.

In 1980, scientists suggested that the great mass extinction of 65 million years ago (which ended the reign of dinosaurs) may have been caused by a large impact from space. What discovery gives a big boost to this idea

Answers

Answer: the discovery of a buried crater (about 200 km across) near Chicxulub, Mexico

The discovery of a buried crater (about 200 km across) near Chicxulub, Mexico.

What is extinction?

Extinction is defined as the disappearance of an organism or a group of organisms as a result of environmental factors or changes in the members' evolutionary processes.

It can also be defined as an evolutionary process that causes a species or population to go extinct.

When there are no longer any living members of a certain animal or plant species anywhere in the globe, the species has become extinct.

Generally speaking, species disappear for the following reasons:

Genetic and demographic phenomena.Habitat destruction in the wild.Species introduction that are invasive.Global warmingHunting and illicit trade.

Answers

Answer:

They do not undergo sexual reproduction.

They form arbuscular mycorrhizae.

Explanation:

Glomeromycota form arbuscular mycorrhizae and they do not undergo sexual reproduction.

Glomeromycota is one of the divisions of fungi that can be found in soils where they form symbioses(association where both glomeromycota and the plant benefits) with the roots of the plants. They can also be found in wetlands. An example of glomeromycota is Acaulospora.

They are also called mycorrhiza. They reproduce through asexual reproduction.

why do wild plants need to reproduce sexually as well as asexually ?

Please answer correctly​

Answers

Answer:

Wild plants would need to reproduce sexually so that there can be variation throughout the species to reduce the number of plants being at risks to certain diseases if the environment is changing. However, the wild plants need to produce asexually if the environment is stable.

Wild plants need to reproduce sexually as well as asexually in order to create variation within a species and lower the number of plants that are susceptible to specific illnesses in a changing environment.

What are wild plants?

Wild plants would need to reproduce sexually. However, if the environment is stable, wild plants must reproduce asexually. Since male and female gametes are not mixed, asexual reproduction produces plants that are genetically similar to the parent plant and increases survival.

A seedling formed from a seed matures more slowly and is less robust than a cutting or bud is taken from an older plant.

Therefore, in order to diversify within a species and reduce the number of plants susceptible to specific diseases in a changing environment, wild plants must reproduce both sexually and asexually.

Some broad-spectrum proteases (protein hydrolyzing enzymes) and nucleases (nucleic acid hydrolyzing enzymes) that function in eukaryotic cells have an optimum pH close to 5.0, whereas the cytosol of most cells is closer to pH 7.0. Which part of a eukaryotic cell might you predict to have a low pH suited to maximizing the activity of these enzymes

Answers

Answer:

lysosome

Explanation:

The lysosome is a membrane-bound organelle found in nearly all eukaryotic cells. The lysosome contains different types of enzymes (i.e., proteases, nucleases, glycosidases, lipases, phosphatases) which are required for the digestion of macromolecules and microorganisms, and recycle macromolecules in the cell. These enzymes are only active in acidic (lysosome) conditions, and they can be deactivated in case of lysosomal rupture because in the cytosol the pH is neutral to slightly alkaline (∼7.3–7.4).

Fenotipo: Parte de la información genética que se manifiesta en el individuo.

Puede definirse como la forma de expresión de uno o mas caracteres por parte del individuo. Muchos factores externos al individuo pueden moldear el fenotipo para hacerlo mas apto al medio. Asimismo el fenotypo y el ambiente actuan en forma conjunta para determinar el destino de los genes en el espacio y en el tiempo.

Cromosoma: Conjunto de ADN con forma de bastón o de X.

Todas las unidades genéticas que llevan información de herencia y que regulan los procesos celulares. Pueden distinguirse claramente durante la división cellar, durante la cual los cromosomas se condensan. La molécula de ADN en eucariotas es lineal y larga, y se asocia a proteinas llamadas histonas y a otras que no son histonas, formando la cromatina. Anted de la division celular la cromatina es laxa, y durante la división se condensa y se define en cromosomas. Cada cromosoma porta diferentes genes.  

Alelo: Variante que determina un caracter (dominante or recesivo)

Los alelos son las distintas formas en las que un gen puede expresarse. Son las formas alternativas de un mismo gen. Resultan d la mutación de un gen original. Estas formas codifican para la misma caracteristica, pero exresando un fenotipo distinto al original.

Genotipo: Contiene el paquete completo de información genética

El conjunto de dos o mas alelos que un individuo tiene en un locus particular. Puede ser

HOMOCIGOTA, si el individuo tiene alelos iguales  HETEROCIGOTA, si el individuo tiene alelos distintos

Gen: Información genética específica localizada en el núcleo de la célula. Fragmento de ADN.

How does the experiment relate to what you've learned about submersible technology suck as submarines and ROV's?

Answers

Answer:

A submersible technology designed to operate the  submarines underwater.

Explanation:

We have learned about submersible technology suck as submarines and ROV's is that pumping system is used to remove water from the submarines and ROV's in order to make it lighter. A submersible is designed to push water to the surface. When a pressure switch is turned on, the impeller started to spin drawing water into the pump. The water is then pushed through the pump and brought it to the surface. Due to removal of water, the submarines and ROV's become lighter and they will come to the surface of water.

What are the functions of saliva?

Saliva is the medium that bathes the taste receptors in the oral cavity and in which aroma and taste compounds are released when food is eaten.

It is composed of water, mucus, proteins, mineral salts, and amylase. As saliva circulates in the mouth cavity it picks up food debris, bacterial cells, and white blood cells.

Saliva moistens the mouth for comfort, lubricates as you chew and swallow, and neutralizes harmful acids. It also kills germs and prevents bad breath, defends against tooth decay and gum disease, protects enamel, and speeds up wound healing.
