What are platelets and platelet adhesion?Platelets are specific types of blood cells that act in order to help blood clot.
Platelet adhesion is a fundamental cellular mechanism that occurs due to situations of vascular injury.
During this process (platelet adhesion) platelets bind via cell membrane receptors to both cell and extracellular matrix.

(d) A shopper in the seafood section of their market believes that purchasing farmed shrimp is a better choice for the environment than purchasing farmed scallops Make a claim using evidence that supports or refutes this assertion
He chooses farmed shrimp because pollution control in farms are more controlled for shrimp.
Farmed shrimp and farmed scallopsCaptive breeding of marine shrimp can only be done when the conditions in which they are cultivated are artificially reproduced.
Farmed scallops are located in the interior, or close to the bays, many of which can be influenced by estuarine waters due to the proximity of rivers, and most of them are shallow. These areas also have a high concentration of suspended inorganic particulate matter (IPM)
With this information, we can conclude that in addition to personal taste, it is necessary to visualize possible risks of contamination in Farmed scallops.

After many decades of being absent from yellowstone national park, gray wolves are being reintroduced. As the wolf populations have increased, elk and bison populations are beginning to decrease. Which is another consequence of the reintroduction of wolves that is likely to occur in yellowstone park?.
Given what we know about the relationships present in this ecosystem, we can confirm that the reintroduction of grey wolves, while causing the population of elk to decrease, will also permit the population of aspen trees and similar plants to increase.
Why would Aspen trees increase in population?The Elk is one of the primary consumers of the aspen tree.
When wolves were removed from the park, their absence caused a sharp increase in the elk population.
This increase in turn caused the elks to consume much more aspen trees and reduce their availability greatly.
The reintroduction of wolves will control the elk population and allow the aspen trees to regrow.
Therefore, given the predator and prey relationships present in the park, we can confirm that with the reintroduction of wolves to the park, we can expect the reduction in elk to allow for an increase in aspen tree populations.

Explanation:
Can modern phylogeny-based taxonomic systems ever produce a satisfactory phylogenetic tree based on DNA
Answer:
Phylogenetic (evolutionary) Tree
showing the evolutionary relationships among various biological species or other entities that are believed to have a common ancestor.
• Each node is called a taxonomic unit.
• Internal nodes are generally called hypothetical
taxonomic units
• In a phylogenetic tree, each node with
descendants represents the most recent
common ancestor of the descendants, and the
• edge lengths (if present) correspond to time
estimates.
Explanation:
Phylogenetic trees are usually based on morphological or genetic homology. A comparison of anatomical traits can reveal an evolutionary relationship among species. Taxonomy, the science of classifying organisms, is based on phylogeny. Early taxonomic systems had no theoretical basis; organisms were grouped according to apparent similarity.
What is the most accurate statement about the interaction between a tree and it’s physical environment

3. Why does an ecosystem with food webs indicate a healthier system than one with a few simple food chains? what do the different trophic levels indicate?.
Answer:
A food web consists of all the food chains in a single ecosystem. Each living thing in an ecosystem is part of multiple food chains. Each food chain is one possible path that energy and nutrients may take as they move through the ecosystem. All of the interconnected and overlapping food chains in an ecosystem make up a food web.
Trophic Levels
Organisms in food webs are grouped into categories called trophic levels. Roughly speaking, these levels are divided into producers (first trophic level), consumers, and decomposers (last trophic level).
