A large population of Yellow perch lives in the East river. The Walleye is a larger fish that eats the Yellow Perch. Despite lots of prey all the Walleye have moved from the East river to a new river. What most likely caused the Walleye to move to a different river?
(A)There is a lack of food in the East river which caused the Walleye to move to a different area.
(B) The Walleye are no longer able to catch the Yellow Perch and need to move to a different area.
(C)There is climate change which has caused the resources to decline in the East river.
(D) There is pollution in the East river that the Yellow Perch are adapted to but the Walleye are not.
Answer:
(D) There is pollution in the East river that the Yellow Perch are adapted to but the Walleye are not.
Explanation:
To ensure survival and cntinurd sustenance in an environment, there is need for an animal to posses certain features which would enable her cope with the conditions of the environment. The ability of animals to successfully live and survive in an environment is made possible through adaptation as the animal's adaptive features ensures the animal is able to live through and cope. If the adaptive features aren't suitable for such environment, then migration has to occurs, leading the animal to find a more suitable environment for survival. In the scenario above, the East river was presumed to be a good habitat for the Walleye and Yellow Perch, in spite of the available and abundance of food, the Walleye migrated, which is most likely due the fact that the Walleye lack the adaptive features to survive in the East river probably due to pollution which the Yellow Perch is well adapted to.
(b) Using the template of the phylogenetic tree, circle the lineages that share node
Complete question:
(b) Using the template of the phylogenetic tree, circle the lineages that share node A. You will find the tree in the attached files.
Answer:
The Lineages that share node A are
Chinese river dolphinAmazon river dolphinLa Plata river dolphinDolphinsNarwhalPorpoisesExplanation:
The phylogenetic tree is composed of,
Lineages → These are the taxonomic groups of interest placed in the extremes of the lines called branches. Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor. Root → This is the older common ancestor that all lineages share. The first one in the tree.- Two or more lineages are more related to each other if they share a recent common ancestor. This means that they all diverge from the same node.
- Two or more lineages are less related to each other if they lack a recent common ancestor. This is, the node from which these lineages diverge is placed far away in the tree.
There are also different phylogenetic relationships between lineages.
Apomorphies → Occur when the involved lineages share a trait that they inherited from their most recent common ancestor. This trait evolved for the first time in this ancestor. → This relationship is a homology.Plesiomorphies → occur when the involved lineages share a trait inherited from a common ancestor, but that is older concerning the present traits exhibited by other descendants of the same common ancestor. → This relationship is a homology.Homoplasy → Lineages share a trait that evolved independently in each group. → This relationship is an analogy.Firstly the question is incomplete the image is not attached with it which shows the phylogenetic tree.
The Lineages that percentage node A are
Chinese river dolphin river dolphinLa Plata river dolphinDolphinsNarwhalPorpoisesThe phylogenetic tree consists of:
Lineages → These are the taxonomic companies of hobby located withinside the extremes of the traces referred to as branches.Nodes → These are the ramification points, that are additionally called divergence points. They constitute the area of the maximum latest not unusual place ancestor.Root → This is the older not unusual place ancestor that every one lineages percentage. The first one withinside the tree.- Two or extralineages are extra associated with every difference in the event that the percentage a latest not unusual place ancestor. In this manner, all of them diverge from the equal node.Two or extra lineages are much less associated with every difference in the event that they lack a latest not unusual place, ancestor. This is, the node from which those lineages diverge is located a long way away withinside the tree.
There also are one-of-a-kind phylogenetic relationships among lineages.
• Apomorphies → Occur while the worried lineages percentage a trait that they inherited from their maximum latest not unusual place ancestor. This trait developed for the primary time on this ancestor. → This dating is a homology.
• Plesiomorphies o( while the worried lineages percentage a trait inherited from a not unusual place ancestor, however, this is older regarding the prevailing developments exhibited via way of means of different descendants of the equal not unusual place ancestor. This dating is a homology.
• Homoplasy → Lineages percentage is a trait that developed independently in every group. → This dating is an analogy.

The purpose of Phase II in rehabilitation is to control inflammation.
O a. True
O b. False
The correct answer is False.
Explanation
Rehabilitation has three main phases, the first of which is the first response to an injury, so the main objective in this phase is to defend the body against harmful substances, eliminate dead or dying tissue and promote the renewal of normal tissue. as well as alleviating pain, controlling the inflammatory response to injury and protecting the affected anatomical area. So you have to clean the wound, disinfect it, cover it, and in cases where it is required to put ice to reduce inflammation.
In the second phase the recovery of functional losses, so it is necessary to start making small movements in the affected area to reactivate its functions progressively.
The third phase is advanced rehabilitation in which functional training work begins with the aim of strengthening and putting the affected area back in a movement directed towards sports practice.
Therefore, the correct answer is False, because the inflammation control is done in Phase I and not in Phase II.

Which property (quality) of fossils allows scientists to determine the relative ages of rock layers?
A.Fossils show change over time as species evolve.
B.Fossils form from the remains of living organisms.
C.Fossils are usually found only in sedimentary rock.
D.Fossils can be analyzed to determine their exact age
The property (quality) of fossils allows scientists to determine the relative ages of rock layers are fossils show change over time as species evolve.
What is the minimum age of a fossil?A living being that lived more than 11 thousand years ago is considered a fossil, that is, before the Holocene, which is the current geological epoch. Ancient remains or evidence, but less than 11,000 years old, such as sambaquis, are classified as subfossils.
Chemistry is present in this process, more precisely the element Carbon. The dating of a fossil can be done based on the already known percentage of Carbon-14 (C14) in relation to Carbon-12 (C12) of living matter (without decomposition).

In an energy pyramid, which level has the most available energy?
A.Producer level
B.First level consumer
C.Second level consumer
D.Third level consumer
Answer:
The correct answer is -A. producer level.
Explanation:
the first trophic level is the level of photosynthetic organisms they produce their food and energy on their own from the ultimate source of energy, the Sun. This is why they are called producers.
Producers have the most energy in any ecological ecosystem as all other organisms get food from these directly or indirectly. Only 10 percent of total energy is transferred from one trophic level from producers to the next tropic level through consumers of different trophic levels.

Transitional fossil evidence shows intermediate steps in the evolution process. So, the correct option is A.
What do you mean by Fossil?Fossils may be defined as the preserved remains, or traces of remains, of ancient organisms. They are dead and organic remains of past organisms.
Transitional fossil evidence would show intermediate forms of a species and they changed and accumulated adaptations at a slow pace. These are remnants of an organism that came in the version of the current species.
Therefore, Transitional fossil evidence shows intermediate steps in the evolution process.

Explanation:
An animal with a larval form that disperses by drifting in ocean currents and an adult form that is attached to a surface is most likely to exhibit ______ as a larva and ______ as an adult. bilateral symmetry . . . bilateral symmetry bilateral symmetry . . . be asymmetrical radial symmetry . . . radial symmetry radial symmetry . . . bilateral symmetry bilateral symmetry . . . radial symmetry
Answer:
Bilateral symmetry as a larva
Radial symmetry as an adult
Explanation:
Bilateral symmetry refers to the division of the animal through a longitudinal plane, int two mirror-image, right and left halves, as seen in organisms such as insects, reptiles or in man. Animals with bilateral symmetry have anterior and posterior halves (head and tail), dorsal and ventral (front and back), and right and left sides. Most animals are bilaterally symmetrical. Animals with bilateral symmetry are best suited for active lifestyles involving streamlined and directional motion.
Radial symmetry refers to the arrangement of body parts around a central axis, just like rays on a sun, ie.they have bodies that seem to radiate outwards from a central point. Animals that are radially symmetrical have top and bottom surfaces only but no left and right sides, or front and back sides. Animals that have radial symmetry are best suited for sedentary lifestyles and are usually attached to some surface (sessile)
An animal with a larval form that disperses by drifting in ocean currents and an adult form that is attached to a surface is most likely to exhibit bilateral symmetry as a larva and radial symmetry as an adult.
