The right optic tract carries information from the lateral half of the retina (right eye) and the medial half of the retina (left eye).
The optic tract is a continuation of the brain's optic nerve. It starts where the signals from the left and right eyes cross (or "decussate") to produce a whole visual image.The left and right optic tracts make up the optic tract, which is actually made up of two independent tracts. Information from the temporal retinal fibers in the left eye and the nasal retinal fiber in the right eye is sent by the left optic tract. The temporal retinal fibers from the right eye and the nasal retinal fibers from the left eye transmit information to the right optic tract.Homonymous hemianopsia, a disorder that results in a partial loss of sight affecting either the right or left eye, can be brought on by damage to the optic tract.learn more about optic tract here: https://brainly.com/question/7283580

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?
The lack of adaptations to the habitat most likely caused the walleye to move to a different river.
Adaptation
It is a biological mechanism that increases the chance of its survival in a new environment or the changes in the existing environment. Adaptation occurs as a result of evolution and allows the organism to survive and reproduce efficiently in its environment.
Physical adaptations include accumulating changes in the physical characteristics of an organism that help them to survive and reproduce better. Example: evolution of long necks in giraffes.
Behavioral adaptations are changes in the behavior or habits of organisms that help them to sustain in a changing or new environment. Example: Hibernation.
Due to some reason, the walleye were not able to adapt to the environment of the east river which is why they must have moved to a new river despite the presence of a lot of prey.

While doing field research, two scientists discover a new species of plant. They take the plant back to their lab to watch how it grows and reproduces. Soon, the plant begins to produce a small purple flower. Upon further investigation, the scientists discover that the plant's seeds contain two embryonic leaves.
Which group could the plant belong to? Check all that apply.
As the new species of plant produced purple flowers, so, the plant belongs to the angiosperms group. Also, the seeds of the plant contain two embryonic leaves, so, the plant must be a dicot.
Out of all five divisions of plants, only the plants that come under the Division Angiosperm can bear or form flowers. That's why angiosperms are also called flowering plants. Angiosperms are further divided into two groups based on the number of embryos that are produced from seeds on germination. If the germinating seeds contain only one embryo leaf, then we call them monocots while the seeds that contain two embryo leaves during their developing seeds, then they are called dicots.Thus, the plant that is discovered by scientists comes under the angiosperm group and further into the dicot group. Dicots have two embryo leaves on germination of their seeds and they also form flowers.

In an active muscle cell, aerobic cellular respiration generates about less than 50 ATP from one glucose.
What is aerobic cellular respiration ?During aerobic cellular respiration, glucose and oxygen combine to create ATP, which the cell can utilise. As byproducts, carbon dioxide and water are produced. The general equation for aerobic cellular respiration is: ATP is produced when glucose and oxygen combine in cellular respiration. The 5 stages that have to take place are glycolysis, oxidation of pyruvate, Krebs's cycle, electron transport chain, and chemiosmosis.
In the presence of oxygen, organisms can employ aerobic cellular respiration to generate up to 38 ATP molecules from a single glucose molecule. Without oxygen, organisms must manufacture ATP by anaerobic respiration, which yields just two ATP molecules for every glucose molecule.

Reptiles are better suited to dry land than their amphibian ancestors because
Group of answer choices
their watertight skin minimizes moisture loss.
amphibians must lay eggs in water or in moist soil to reduce moisture loss.
reptile egg shells are harder than amphibians' eggs.
all of the choices
Answer:
All of the above.
Explanation:
1. Their watertight skin minimizes moistures loss: Reptiles have a reputation that they are “slimy” when we touch and hold them; however, they have dry skin, which has even fewer glands than mammals or amphibians. The main special feature of their skin is that the epidermis is heavily keratinized with a layer, which also prevents water loss.
2. Amphibians must lay eggs in water or in moist soil to reduce moisture loss: Because amphibian eggs don't have an amnion, the eggs would dry out if they were laid on the land, so amphibians lay their eggs in water.
3. Reptile egg shells are harder than amphibians' eggs: Reptile eggs are coated with a leathery or brittle coating, and the animals that hatch from them are miniature versions of the full-sized animal parent. In contrast, amphibian eggs are transparent and jelly-like. The animals that hatch from them still must go through metamorphosis.

Explanation:
The type of rocks in which dinosaur fossils (and almost all other fossils) are found is called sedimentary rock. Sedimentary rock generally occurs as flat layers called strata (single layers called stratum). Imagine you have a handful of both coarse and very fine sand and a bucket of water. If you were to drop the sand into the water two things would happen. First, the sand would settle to the bottom of the bucket. The coarse sand would settle faster and then the fine sand would slowly settle out. Secondly, when the sand reached the bottom of the bucket it would spread out forming two flat layers, a layer of coarse sand covered by the layer of fine sand. The process of settling is called sedimentation from the Latin, sedimentum, meaning the act of settling. The layers formed across the bottom of the bucket are called strata, from the Latin word stratum, meaning covering.
Virtually the identical process occurs in nature. Imagine a river carrying lots of sand and other material worn from rocks emptying into a large body of water like a lake or ocean. Flat layers are created on the bottom of the body of water. Dinosaur bones carried by the river would also settle out and be found in one of the layers on the lake or ocean bottom. Eventually it would be covered by subsequent layers. Over time, the soft layers would be turned into rock, the bones would be preserved within the layers, and finally they might be raised to the surface where a lucky paleontologist might recover them for a museum.
Looking for bone layers is much like playing detective. Using 4.6 billion years as the age of the Earth and 164 million years for the tenure of dinosaurs on the planet, it is easy to determine that dinosaurs existed on Earth for only a very short part of the Earth's history (only 3.6% of the time). Holmes (see References below) lists a maximum total thickness of 452,000 feet of rocks that are known to contain fossils of animals with hard parts; only 125, 000 feet of which were deposited when the dinosaurs existed. If only 28% of the fossil-bearing rock thickness may contain dinosaur fossils, how do we search for them?
The first thing we must do is narrow the search. We must first locate the 28% of sedimentary rocks in which dinosaur fossils may be found. Let's consider an ideal situation. A paleontologist from Texas went on vacation to Montana where he discovered dinosaur bones in a particular layer of rock. He wondered if the same layer existed in Texas so he could find bones closer to his home. If that particular rock layer appeared on the Earth's surface, continuously, all the way from Montana to Texas he would be able to walk along the layer to follow it. That would be easy, but, unfortunately, the easy way never seems to work. In many cases the bonelayer would be covered by layers of younger rocks, and in other cases the bone layer could be worn away by erosion. Both covering and erosion would make it impossible to follow the layer from Montana to Texas. Clearly, another method must be found. One of the most reliable ways to locate fossils is with other fossils. Certain widely found fossils represent animals that only lived on Earth for a very short time. Such fossils are called index fossils. When found in two geographically separated layers, they allow scientists to say, with some confidence, the layers are the same. Index fossils can be used to track a layer from Montana to Texas, or from Montana to France. The process of determining if layers in different places are the same is called correlation.
Return to top
Once the layer is found, more work needs to be done. Dinosaurs probably did not live everywhere in that layer. We know that dinosaurs did not live in the oceans. We can avoid searching in areas that fossils tell us were oceans at the time of the dinosaurs. Fish and marine reptiles (such as plesiosaurs) did not live in the same places as dinosaurs. If paleontologis ts find the former, they won't find the latter. Index fossils allow us to not only determine what layers contain other fossils, but also where in that layer certain fossils may be found

anaphase II
telophase II
The image shows the phase of cell division called telophase II.
What is Telophase II?It is the last phase of mitosis, the sister chromatids separate, the chromosomes decondense, the achromatic spindle breaks down and the karyotheca, and consequently the nucleoli, reappear. With cytokinesis, in telophase I two daughter cells are formed and continue in the process of division until telophase II.
In this case, we can see in the image that the chromosomes decondense so we have telophase II.
