There are no PHOTORECEPTORS in the OPTIC DISC located where the nerve fibers of the RETINA leave the eye and enter the OPTIC NERVE. This region is commonly called the BLIND SPOT.
The retina is an important layer of nervous tissue that covers the inside of the eye, in which the sensation of vision initiates.
Photoreceptors are specialized cells within the retina that respond to light stimuli. In the retina, there are two types of photoreceptor cells: cones and rods.
The blind spot is a small portion of the visual field of the eye that localizes in the optic disk within the retina.
There are no rods or cones (i.e. photoreceptor cells) within the optic disk.

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.

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.
