She postulates that this is due to primarily to coevolutionary relationships that are different in different areas due to the distribution of various parasites and mutualistic partners of the lobster species. If this hypothesis is correct it would be a clear example of mosaic coevolution.
According to the mosaic hypothesis of coevolution, geographic location and community ecology influence the different coevolution between closely related species in various populations. These populations might be divided in terms of time or location. Interspecific relationships can be mutualistic or hostile depending on the ecological circumstances. In mutualisms, both individuals gain from the encounter, whereas in antagonistic interactions, one partner typically has decreased fitness.Arms races involve two species figuring out how to "one up" each other. These correlations are influenced by a number of variables, such as trait mixing, hot regions, and cold places.

These populations may be separated based on time or place. Depending on the ecological context, interspecific relationships might be friendly or hostile.
In mutualism, both parties benefit from the interaction, whereas one party often has worse fitness in hostile interactions.
Arms races occur when two species try to outdo one another.

What is unique about how fish live in groups?
Answer:
Fish generally prefer larger groups over smaller groups. They prefer groups with similar species.
Explanation:
Offspring inherit _________________; if one or both parents passes on a gene with DNA that does not code for functional proteins, disorders like phenylketonuria can result.
Offspring inherit one copy of each gene from both parents if one or both parents passes on a gene with DNA that does not code for functional proteins, disorders like phenylketonuria can result.
How do parents pass on one copy of each gene to their children?Their mother passes one copy on to them through the egg, while their father passes the other one along (via the sperm). Each egg and sperm have a single set of 23 chromosomes. Two copies of each chromosome and two copies of each gene are present when the sperm fertilizes the egg, resulting in the formation of an embryo.
An autosomal recessive metabolic genetic condition called phenylketonuria (PKU) is defined by a mutation that renders the gene for the hepatic enzyme phenylalanine hydroxylase (PAH) inactive.

What will happen to blood flow if the resistance to flow increases, while the pressure gradient across a blood vessel remains constant
Answer:
As resistance to flow increases, blood flow will decrease
Explanation:
Resistance is a force that opposes the flow of a fluid. In blood vessels, most of the resistance is due to vessel diameter. As vessel diameter decreases, the resistance to flow increases and blood flow decreases.
One problem with eradicating invasive species is that sometimes the disturbed area is unable to be colonized by native species. For example, in forests where the invasive plant garlic mustard has been removed, native plants and animals do not recolonize because they are extinct in that patch of forest. How should restoration ecologists increase species diversity and recover ecosystem function
In forests where the invasive plant garlic mustard has been removed, native plants and animals do not recolonize because they are extinct in that patch of forest. Restoration ecologists should Develop movement corridors for primary producers to increase species diversity and recover ecosystem function.
Patches are connected by corridors, which improves the watershed's overall habitat quality. They offer relatively risk-free access for wildlife to a variety of habitat resources that are often distributed throughout the terrain and may fluctuate with the seasons and temperature. Instead of being linear habitats, movement corridors, also known as dispersal corridors or landscape links, serve as a link between at least two key habitat areas.According to certain theories, corridors for primary producers facilitate the movement of species between different habitat areas, fostering genetic exchange and lowering population fluctuations.learn more about invasive plant here: https://brainly.com/question/1542287

Native plants and animals do not recolonize in forests where the invasive species garlic mustard has been eradicated because they are extinct in that area of the forest. To boost species variety and restore ecosystem function, restoration ecologists should create movement corridors for primary producers.
What are primary producers?Primary producers are organisms that can make their own food, such as plants and phytoplankton, through photosynthesis or chemosynthesis.
Patches are connected by corridors, which enhances the overall habitat quality of the watershed.
They give wildlife reasonably risk-free access to a variety of habitat resources that are frequently dispersed over the landscape and may change with the seasons and temperature.

what are the cause of thrombosis
Answer:
Injury to the vain.
Explanation:
Thrombosis is affected by virchows triad of stasis, turbulence and coagualability of the blood. An increase in any of these three can cause thrombosis.
The blood pools in the legs when we stand or sit and we very rarely are in a situation where gravity aids in draining blood from the legs. The body forces the blood up the legs by squeezing it up when we contract our leg muscles. We have one way valves in these veins to prevent the blood from falling back down the vein. So if we are in a situation where we are vertical for long periods of time or not moving our muscles or have had a previous thrombosis that has damaged our venous valves this can further increase the stasis already present in the legs and precipitate a thrombosis. It is this predisposition to stasis that causes dost thrombosis to occur in the legs.
Flying causes DVTs for this reason as we are sitting still for long periods of time. Also the recycled air can cause dehydration which increases the coagulability of the blood.

What type of cytotoxic T cells respond to foreign antigens only in association with class I MHC glycoproteins
CD8+ type of cytotoxic T cells responds to foreign antigens only in association with class I MHC glycoproteins.
What are cytotoxic T cells?
Cytotoxic T cell is a particular class of immune cell that is capable of eliminating specific types of cells, such as virus-infected cells, cancer cells, and alien cells. To destroy cancer cells, cytotoxic T cells can be isolated from other blood cells, cultured in a lab, and then administered to a patient.
Helper T cells binding to a processed antigen on the same dendritic cell as the MHC-class II presenting a processed cancer cell antigen enhances cytotoxic T-cell complete activation. Cytotoxic T cells release two cytokines in particular, TNF-alpha and IFN-gamma, which facilitate the activation of macrophages.
