According to the theory of plate tectonics what drives the motion of the contenients

Answers

The theory of tectonic plates explains that large convectional currents occuring in the mantle(as a result of magma) are the reasons plates,and so continents,are moved. Note movement occurs in the boundary in between the plates.

Answer:

The theory of plate tectonics is what brings together continental drift and seafloor spreading. Plates are made of lithosphere topped with oceanic and/or continental crust. The plates are moved around on Earth's surface by seafloor spreading. Convection in the mantle drives seafloor spreading. Oceanic crust is created at mid-ocean ridges. The crust moves outward from the ridge over time. The crust may eventually sink into the mantle and be destroyed. If a continent sits on a plate with a mid-ocean ridge, the continent will be pushed along.

It is difficult to define Primates according to the presence or absence of certain distinguishing anatomical or behavioral traits. What *really* defines Primates is that they all are descended from a single common ancestor approximately 65 million years ago.

Answers

Answer:

The correct answer is - true.

Explanation:

Primates are the third diverse group of mammals after rodents and bats. It is considered that it has diverged from other terrestrial mammals about 65 million years ago.

Defining and identifying the primates on the basis of certain anatomical and behavioral traits is not an easy task. There are almost 400 living species of primates are known.

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.

does the presence of introns exons in eukaroytic cells provide more potentia diversity in gene products than is possible in porkatroi cells

Answers

Answer: Yes. Splicing can be done in different ways to yield different mRNAs wich will create different proteins. Prokaryotes are not able to do this.

Explanation:

DNA (deoxyribonucleic acid) is a molecule that contains the genetic information for synthesizing amino acids that form proteins. To do this, DNA must first be transcribed into RNA (ribonucleic acid) and this is the molecule used for protein synthesis (translation). The newly transcribed RNA (called primary messenger RNA) from DNA results in a very long molecule and also has regions that do not code for anything, called introns, which are removed by a process called splicing. Exons are segments in the RNA that do code for amino acids and remain in the mature mRNA after splicing.

Splicing is a process by which introns are cleaved from the primary messenger RNA and exons are joined to generate mature messenger RNA. In addition, alternative splicing occurs which allows different mRNA isoforms and thus different proteins to be obtained from a primary mRNA transcript. This is because the exons will be joined or spliced in different ways, giving rise to different mature messenger RNA sequences. This process occurs mainly in eukaryotes, although it can also be observed in viruses. But it does not take place in Prokaryotes (Bacteria).

In summary, exons/introns can be spliced together in different ways to yield different mRNAs sequences. Each different mRNA sequence will code for a different protein.

An effective and intricate mechanism has been evolved in the immune system to fight off invading invaders. These systems also contribute to the refusal of the transplanted bodies that are recognized by the immune system of the receiver as foreign.

What is a technique that aims to reduce viable spoilage microorganisms so they are unlikely to cause disease?

Answers

Answer:

Pasteurization

Explanation:

Food products such as milk, wine and beverages may be subjected or placed on a heat treatment process with the aim of reducing active microorganisms present in them. This will improve the quality of food materials and also prolong its life span. This heat treatment process help destroy pathogenic microorganisms and those which are responsible for food spoilage. Once this food spoilage microorganisms are destroyed, the good products will have enhanced or prolonged life span of the food product and also reduces their risk of causing disease.

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.
