Looking at the image of the freshwater lake ecosystem in the reading, can you name biotic and abiotic factors in this specific ecosystem? What changes in this ecosystem would impact the biotic factors?
Answer:
Biotic: Fish, Plants, Animals, Some bacteria in the water
Abiotic: Water, Sunlight, Rocks
Changes to any ecosystem can affect the way organisms live. It can be a big change like having to adapt to their surroundings. An example is being camouflaged, or having an increase in population. Bad changes can lead to population decline, or maybe even being extinct.
Explanation:
There isn't really an image to see, but I put what I could think would be in a lake ecosystem.

Myasthenia Gravis is a disease characterized by the production of antibodies against nicotinic acetylcholine receptors resulting in a decrease of functioning receptors at Motor end plates. Physiologically, what might you expect to happen as a result?
a. clonus
b. increased frequency of motor neuron firing
c. chorea
d. paralysis of skeletal muscle
Answer:
The correct answer is - option d.
Explanation:
Myasthenia gravis is an autoimmune condition in which nerve endings are targeted due to the body produces antibodies against receptors of nicotinic acetylcholine which results in less or no functioning of nerve endings of motor neurons mostly.
Options A, B, and C all three conditions are all due to an increase in muscle movement which is not the case as it causes weakness in the muscles due to less functioning in motor end plates.

Answer:
yes it is
Explanation:
people need goals!
Two parents, both with brown eyes, have four children. One child has brown eyes, like his parents, but the other three all have blue eyes. One of the children has been learning about genetics in science class and knows that brown eyes are dominant to blue eyes in humans. The student developed the following model of a Punnett square to predict the genotypes of his parents and his siblings.
Based on his model, the student claims that only one of the four children should have blue eyes. Which of the following explanations best describes why the Punnett square does not model the traits in the student’s family? (DOK 3)
Answer:
Punnett squares are not exact answers, they are only used to predict traits.
A.
The student is forgetting that a Punnett square is used to predict the outcomes of a genetic cross. The actual results do not always match up to the predicted outcomes.

Why do waves move faster at higher temperatures and in a solid phase?
O There is more energy and the particles are farther apart.
O There is less energy and the particles are closer together.
O There is less energy and the particles are farther apart.
There is more energy and the particles are closer together.
Answer:
B
Explanation:I took the test if u need help follow me
Waves move faster in higher temperature and in solid phase because there is more energy and the particles are closer together.
What is meant by intermolecular force ?Intermolecular force is defined as the force of attraction experienced between the neighboring molecules in the same state.
Here,
During higher temperature and when in a solid phase, the waves exhibit movements very faster than in other phases.
This is because, when the temperature of the system is increased, the energy of the molecules in the system will be increased to a higher level. This energy formation is in the form of kinetic energy of the molecules.
Molecules in the solid phase have a greater intermolecular force of attraction with their neighboring molecules. Therefore, the molecules in the system will be more closer to each other.
As the kinetic energy of the molecules in the system increases, the molecules will start vibrating. These vibrating molecules induces the vibration to their neighboring particles, since they are closer together.
As a result, more and more highly energetic molecules are set to vibrate, which causes the wave to move faster in the system.
Hence,
Waves move faster in higher temperature and in solid phase because there is more energy and the particles are closer together.

are there exits alloted for emergency escape plan? how many?
Answer:
The correct answer is - yes, multiple exits but a minimum of 2 is a must.
Explanation:
An emergency escape plan is a documented map or plan of a building that is created for the safe evacuation in an emergency such as fire, smoke, natural disaster, or any panic situation.
In an emergency escape plan, there must be easy exits for faster and safe evacuation even in low visibility or smoke condition. Multiple exit routes are allowed to any escape plans, however, two is the minimum number of exits is compulsory.
Yes, there are exits alloted for emergency escape plans. It should be multiple in number but a minimum of 2 must be necessary.
What is an emergency escape plan?An emergency escape plan is the urgent immediate egress or escape of people away from an area that contains an imminent threat of destruction, an ongoing threat, or a hazard to lives or property.
An emergency escape plan provides a path for the people of a particular area to move away from the risky or threatened places immediately. So, emergency exits play a significant role when there is any natural disaster, fire, smoke, etc. has occurred.
Therefore, there are exits alloted for emergency escape plans. It should be multiple in number but a minimum of 2 must be mandatory.

Metamorphic rocks are a bit harder to identify because they can share traits with the other rock types. Again, thinking about the formation process can help. Metamorphic rocks have been heated and squashed. This can lead the minerals in them to line up, creating ribbon-like layers called bands. These rocks are called foliated metamorphic rocks. You can see these bands in gneiss. If a metamorphic rock has fossils, you know it was formed from a sedimentary rock. Because of the heat and pressure, the fossil will be hard to recognize and out of shape.
Which of the following best describes foliated metamorphic rocks?
A
There are easily recognizable fossils.
B
The rock has ribbon-like layers of bands.
C
They have crystals like igneous rocks.
D
Different sized sediments can be see
Answer:
b
Explanation:
the fourth sentence in the passage: "This can lead the minerals in them to line up, creating ribbon-like layers called bands."
Dark and light bands may alternate due to the separation of mafic (dark) and felsic (light) minerals. Having different grain sizes in the same mineral can also result in banding. Thus, option B is correct.
What are the ribbon layer present in the rock?Under the surface of the earth, metamorphic rocks are formed. The extreme heat and pressure cause them to alter. Their layers resemble ribbons. Some of them are covered in bright crystals.
Under the earth's surface, metamorphic rocks are created as a result of the transformation brought on by extreme heat and pressure (squeezing).
These processes produce rocks that frequently have layers that resemble ribbons and may have glittering crystals on their surface that were created by minerals slowly growing over time.
Therefore, This can lead the minerals in them to line up, creating ribbon-like layers called bands
