Which is not a similarity between terrestrial and aquatic pyramids? a. both have producers as the base that can harvest the sun’s energy to make food b. both types still consist of producers, herbivores, and carnivores c. both types of energy pyramids contain the same species of organisms d. both types contain a decreasing number of organisms going from the bottom to the top of the pyramid please select the best answer from the choices provided a b c d
The option that is not a similarity between terrestrial and aquatic pyramids is c. both types of energy pyramids contain the same species of organisms.
The organisms living on land and those living in water are different from each other. As specific adaptations are required for organisms to survive on land and water hence these organisms are completely different from each other and do not belong to the same species.
The structural differences such as the presence of gills, having a streamlined body, no legs, etc are some of the qualities that are found in aquatic organisms. On the other hand, terrestrial organisms have to breathe through their lungs, and usually have legs along with various other adaptations to survive on land.
Hence, as both aquatic and terrestrial organisms have completely different adaptations to survive in their environments, they do not belong to the same species of organisms.

Water covers over two-thirds of Earth’s surface. Yet water shortages are a major problem for many people around the world. Why do you think this is the case?
Freshwater scarcity and global temperature and weather variations are to blame for the lack of water on land because they receive so little rain to replenish ground water, rivers, lakes, and other water bodies, temperate regions appear to suffer more.
Reason for the shortage of water may include:
Seawater has the ability to evaporate before condensing into clouds.A cloud's gaseous water can condense, then freeze to form a glacier.Oceans contain the majority of the planet's water. In actuality, the U.S. Geological Survey estimates that only 2.5% of the world's water is freshwater. That water is also not regularly accessible or distributed evenly. Streams, rivers, lakes, and wetlands only hold roughly 0.3% of the freshwater or Seawater has the ability to evaporate before condensing into clouds.So these are the reasons why the shortage of water is there on earth inspite of the fact that two-third of its surface is covered with water.

) you are decellularizing a porcine artery for use as a small diameter vascular graft. what in vitro assay(s) could you use to determine whether the resulting decellularized xenogeneic tissue would be rejected by a human host
Decellularized porcine saphenous artery for small diameter tissue engineered conduit grafts.
Overview:
Decellularized xenografts have been identified as potential scaffolds for small-diameter vascular grafts. The purpose of this study was to biomechanically transform the porcine decellularized saphenous artery (DPSA) by a modified decellularization process using a Triton X-100/NHOH solution and serum-containing medium.
The goal was to develop and explore functional, biocompatible acellular conduits. Histological and biochemical analyzes showed a high degree of cell clearance and extracellular matrix preservation. Burst pressure tests showed that DPSA can withstand pressures of 1854 ± 164 mm Hg.
In vitro cell adhesion and biocompatibility evaluations showed that porcine pulmonary artery endothelial cells can adhere and grow on DPSA in static and rotary cultures. After implantation into the rabbit carotid artery in vivo, DPSA showed a patency rate of 60% at 1 month and 50% at 3 months.
No aneurysm and intimal hyperplasia were observed with any of his DPSA. All patented grafts showed regeneration of vascular elements and thrombotic occlusion was found to be the major cause of graft failure.
This is probably due to residual xenoantigens. In summary, this study demonstrated the development and evaluation of a decellularization process that could be used as a small-diameter graft.

Antibiotic resistance enhances the reproductive success of bacteria that have it.
a. true
b. false
True, Antibiotic resistance enhances the reproductive success of bacteria that have it.
Reason for Reproductive success- The bacteria achieved the antibiotic resistance by the resistance gene only which pass on the next bacteria (by vertical gene transfer), or by horizontal gene transfer which again provide the resistance to the antibiotic which finally leads to the reproductive success and ultimately the bacterial colony will survive.
Horizontal Gene Transfer- The transmission of antibiotic-resistant genes amongst bacteria (apart from those that are passed from parent to child) is a result of horizontal gene transfer (HGT), which also promotes the development of pathogens.
Vertical Gene Transfer- Genetic material is passed on from parents to children. Through sexual or asexual reproduction is a possibility.

Lionfish have extremely few predators because they are not endemic to Atlantic seas.The biggest issue with lionfish is its wide appetite, which has had a significant impact on the local environment despite the fact that they have easily adapted into Atlantic waters.

A model is a three-dimensional representation that is scaled down, a simplified description of a system, a figure that can be replicated in any material, a specific design or style of a structure or convenience, a model person, thing, or ideal, an example of a person or thing that can be copied or imitated, or a person to pose or be shown, according to the English language dictionaries.
The term is difficult to define and reconcile because it has so many different connotations. The qualification of new information is one of the oldest problems in experimental research. Because of this, one of science's main goals has been to discover an experimental model in order to develop knowledge more uniformly.
Finding a model for knowledge generation is important since it is necessary to fully understand the procedures that result in this fact. The greatest strength of the experimental model is its capacity to concurrently comprehend assumptions, control results, and technique.

The compounds glucose and galactose that has a free alpha carbonyl group are the ones that give a positive test for glucose.
What is the test for glucose?We know that glucose is a reducing sugar. The glucose molecule contains the -CHO group or the aldose group which is free in the open chain structure of the compound. The fact that this alpha carbonyl group is free in glucose is the reason why glucose is able to react with the Benedicts solution and give a positive test.
On the other hand, the sucrose and the lactose molecules are dimers hence the alpha carbonyl is not free. Given the fact that the alpha carbonyl in these structures are not free, they do not give a positive test for glucose though they contain glucose monomers.
Fructose is not a reducing sugar. The fact that it is not a reducing sugar explains why it does not give a positive test for with the Benedicts solution.

3. Summarize the reproductive strategies of r-strategists and k-strategists
for ensuring continuation of their species.
R stands for the slope of the graph depicting exponential growth in the equations that describe the growth of different organisms. The capacity factor of an ecosystem for individuals belonging to a specific type of creature is symbolised by the letter K.
Ecologists have also used the phrases "r-selection" and "K-selection" to refer to diverse organisms' growth and reproduction processes. Larger, more enduring, producing fewer progeny at a time, and displaying logistic growth are characteristics of K-selected species. R-selected taxa are those that live shorter lives, are typically smaller, have a large number of offspring, and have exponential growth. The terms "r-strategy" and "K-strategy" come from population biology mathematics and designate two points on a continuum where gamete production and longevity engage in a compensating exchange (the K-strategy). Depending on the local conditions at any particular time, many species choose an intermediate strategy or even other strategies altogether. In reality, an organism that can switch between a r- and a K-strategy may be the most suitable organism overall because of its capacity for adaptation, which enables survival under a wider range of circumstances.
