Students observe several slides of tissue cross-sections under the microscope. They are asked to develop a key system to classify the slides as coming from either monocot or dicots. What key system should the students develop
As students observe several slides of tissue cross-sections, one simple key they can use to determine if the slides come from dicots or monocots is to analyze the vascular bundles.
A vascular bundle is described as a portion of the transport system of vascular plants. These bundles are microscopically different in Monocots than they are in Dicots, which will allow students to tell them apart through the tissue slides.
The difference is that monocots contain randomly scattered bundles located throughout the stem. On the other hand, dicots have their vascular bundles more neatly organized in concentric circles. These microscopic differences can serve as a key to be used by the students to classify the tissue samples they are studying.

What are some of the posible signals of male quality in widowbirds and what information might they convey? What are the females choosing and why
Male produces signals of bright red, yellow epaulets and long tails.
Males produce bright red and yellow epaulets as well as chevrons on their wings. These bright epaulets attracts the female of this species and helps in the sexual activity of widowbird species.
The males of several widowbird species also grow long tail feathers about half a meter in length. The long tail is favored by sexual selection through female choice of mates. Female prefer long tails red-collared widowbird so we can conclude that male produces signals of bright red, yellow epaulets and long tails.

1) The biological levels of organization range from a single cell all the way up to the biosphere in a highly structured hierarchy. The biological hierarchy includes cells, tissues, organs, organ
systems, and organisms. Muscle is a type of tissue meaning it is made of groups of cells working together. However, the three types of muscle tissue are specialized for different functions.
What do all three types of muscle tissue have common? Select ALL that apply
A) Muscle cells all contract.
B) Muscle cells are all striated
Muscle cells all cause movement
D) Muscle cells are all cylindrical
E) Muscle cells all have one nuclei.
Answer:
A C D
Explanation:
Got it right
All three types of muscle tissue have three things in common: Muscle cells all contract; muscle cells all cause movement, muscle cells are all cylindrical; that is, they have the same similarities as options A, C, and D.
What are muscle cells?All three types of muscle tissue—skeletal muscle, smooth muscle, and cardiac muscle tissues have some common features, such as being composed of elongated cells and having the ability to contract and generate force that enables muscle tissue to cause movement, such as the movement of a limb, the beating of the heart, etc. Skeletal and cardiac muscle cells are striated, meaning they have alternating bands of dark and light regions, while smooth muscle cells are not.
As a result, muscle cells all contract; muscle cells all cause movement; and muscle cells all have cylindrical shapes, i.e., options A, C, and D.

Describe how gravity is associated with many erosional agents.
Answer:
Gravity is associated with many erosional agents, because the force of gravity tends to pull all material down the slope. is when a rill channel evolves to become deep and wide. glaciers are dense so they can carry large rocks and debris for a long distance.
Role of gravity in erosion, because gravity tries to draw everything down the slope, gravity is linked to numerous erosional agents.
What are erosional agents?Glaciers and running water both erode due to gravity. This is a result of gravity pulling water and ice downward. These are examples of indirect effects of gravity on erosion.
Due to the force of gravity, mass movement is an erosional process that carries rocks and sediments down slope. The material is moved from higher heights to lower elevations, where it can be picked up and moved to even lower levels by other carrying mechanisms like streams or glaciers.
Therefore, glaciers and running water both erode due to gravity. This is a result of gravity pulling water and ice downward. These are examples of indirect effects of gravity on erosion.

Two phosphoanhydride bonds, which have high energy, connect these three phosphate groups, hence c and d store energy within the molecule.
How does energy store in an ATP molecule?An adenine base is joined to a ribose sugar, which is joined to three phosphate groups, to form the nucleotide ATP. Two phosphoanhydride bonds, which have high energy, connect these three phosphate groups.
At the cellular level, energy is used and stored as adenosine triphosphate (ATP). Adenine, ribose sugar, and three serially bound phosphate groups make up the structure of ATP, which is a nucleoside triphosphate.
Therefore, the structure of ATP is a nucleoside triphosphate having Two phosphoanhydride bonds, hence c and d store energy within the molecule.

At a fair or circus, some performers and clowns take long balloons and fold them into animals and objects as toys for children. Which statement explains why the balloon can fold, twist, and bend without bursting?
A. There is no matter that exists inside a balloon, so there is nothing that can cause the balloon to burst when it is folded, twisted, and bent.
B. The balloon is filled with air, which is a mix of gases. Air is fluid and can move around the inside of the balloon as it is folded.
C. The balloon is made of a flexible material so it can be changed into different shapes without ever bursting.
D. The balloon is filled with air, which is a mix of gases. The pressure of the air inside the balloon makes it rigid enough to look like an animal.
Good Luck :D ! Subject: Science
The statement which explains why a balloon can fold, twist, and bend without bursting is: B. The balloon is filled with air, which is a mix of gases. Air is fluid and can move around the inside of the balloon as it is folded.
A balloon can be defined as a flexible rubber bag that can be inflated with a gas such as air.
Generally, air can be trapped in a balloon by sealing its neck tightly.
Hence, this makes it possible for performers and clowns to fold, twist, and bend an inflated balloon into animals and objects as toys for children.
A inflated balloon can be folded without it bursting simply because air is fluid and as such, it would move around the inside of the balloon as it is folded.
In conclusion, air, which is a mixture of gases would move around the inside of the balloon as it is folded because it is also a fluid.
