3. Which of the following apply to skeletal muscle? (Choose all that apply) 1: striated 2: involuntary 3 : voluntary 4 : used for movement
Answer:
striated
voluntary
used for movement
Explanation:
Skeletal muscle is:
→ striated - they are marked with long, thin parallel streaks
involuntary - they aren't done without will or conscious control.
→ voluntary - they are done out of one's own free will.
→ used for movement - they allow you to perform a wide range of movement
Drag each label to the correct location on the diagram.
Identify the structures of skeletal muscle.
fascicle
muscle
myofilament
muscle fiber
myofibril
The skeletal muscle, responsible for voluntary contraction is composed of 1) Myofilaments 2) Myofibrilles 3) Muscle fibers 4) Muscle (from the left to the right in the image)
What is the composition of the skeletal muscle?
The elements composing the skeletal muscle are,
Myofilaments ⇒ Actine and miosineSarcomere ⇒ It is the functional unit with the contractile apparatus. Composed of the Z band, A and I bands, and H zone.Myofibrilles ⇒ They have the Functional unitsMuscle fibers ⇒ Surrounded by endomysiumFascicle ⇒ Group of fibers surrounded by perimysium.Muscle ⇒ Group of fascicles surrounded by epimysium.The sarcomere is the contractile unit in a skeletal muscle. The thick myosin myofilaments are located in the central region of the sarcomere, which corresponds to the A band.
Thin filaments united to the Z lines, extends to the interior of the A band until they reach the border of the H band.
The I band is formed solely of thin actin filaments, belonging to two sarcomeres adjacent to a Z line.
When the muscle contracts, the muscular fiber gets shorter and thicker due to the reduction in length of the sarcomere.
The H line and the I band get shorter. The Z lines get closer to the A band, meaning that they get closer to each other. The A band keeps constant in length.This change is produced by movement mechanisms that involve a change in the relative position of actin and myosin filaments.For a better understanding about muscle contraction, look at the attached files.

importance of protein in metabolism
Answer:
Protein is also used for growth and repair. Amid all these necessary functions, proteins also hold the potential to serve as a metabolic fuel source. Proteins are not stored for later use, so excess proteins must be converted into glucose or triglycerides, and used to supply energy or build energy reserves.

Bona has started reaction to the sound of a loud "POP". immediately before the pop,a light flashes.after several times.bona has started reaction the flash of light.
A. what is unconditional stimulus
B, what is confidential stimulus
C, what is NS
D, what is unconditional response
The flash of light thus associated can now be called the conditioned stimulus.
What is stimulus?The term stimulus has to do with response to particular occurrence. This is well captured in the area of behavioral psychology. We know that the organism can be trained to respond to a certain stimulus when it is presented.
Now if a stimulus elicits a particular reaction and then another stimulus is presented immediately after the first one such that the organism learns to associate the second stimulus with the first, the organism would over time begin to respond to the second stimulus in the same manner as the first.
Now we can see that in this case, the light flash follows the POP sound. This implies that organism would overtime associate the sound and the light. This flash of light thus associated can now be called the conditioned stimulus.

Storm winds knock down trees in part of a forest. Which of these effects of
the storm winds is a negative consequence?
A. A new clearing attracts new animals.
B. The fallen trees become food for decomposers.
C. Organisms living in the fallen trees lose shelter.
D. More light reaches shorter plants.
Answer:
C. Organism living in the fallen trees lose shelter.
Explanation:
talking about the effects of storm winds falling trees, it creates more light to reach shorter plant which will help the plants to do photosynthesis well, which will even facilitate their fast growth; that's positive.
Fallen trees becoming food for decomposers can also be positive cause this will help the soil or earth of that forest have fertility
New Clearing attracting animals such as man can lead to extinction of forest which to conservators they feel like no-no-no-no that's they'd see it as a negative consequence of the wind storm effect, yes this can lead to de-sheltering of organisms inhabiting that niche(trees)

The probability that the offspring of the parents who are both heterozygous in a dihybrid cross are also heterozygous for both genes is 0.25
What is a dihybrid cross?A dihybrid cross is a cross in which two different traits are involved in the crossing.
For example, the trait for height and color of hair in two parents being crossed is a form of a dihybrid cross.
Assuming two two traits are Ss and Yy, where the dominant traits are S and Y and the recessive traits are s and y.
The two individuals are heterozygous for both genes means that their genotype are both SsYy.
The dihybrid cross is shown in the attached image;
Based on the attached image, the heterozygous offspring for both genes SsYy are 4 out of the possible 16 offspring.
The probability of offspring that are heterozygous for both genes = 4/16 = 0.25
In conclusion, in a dihybrid cross, two traits or genes are involved in the cross and a possible number of 16 offspring are produced from the cross.

Explain the structure and function of tissue systems in plants.
Answer:
Key Takeaways: Plant Tissue Systems
Epidermis is a thin cell layer that covers and protects underlying cells. The outer periderm, or bark, is a thick layer of nonliving cork cells. Vascular tissue is composed of xylem and phloem. These tube-like structures transport water and nutrients throughout the plant.
Answer:
function of tissue system:
Dermal tissue covers and protects the plant, and vascular tissue transports water, minerals, and sugars to different parts of the plant. Ground tissue serves as a site for photosynthesis, provides a supporting matrix for the vascular tissue, and helps to store water and sugars.
Explanation:
structure of tissue system:
Vascular tissue transports water, minerals, and sugars to different parts of the plant. Vascular tissue is made of two specialized conducting tissues: xylem and phloem. Xylem tissue transports water and nutrients from the roots to different parts of the plant, and also plays a role in structural support in the stem.

When blood glucose levels is too high, insulin is secreted and is responsible for increasing the absorption of glucose into the body cells for its own use which decreases the blood glucose level to normal levels. Insulin regulates blood glucose levels.
On the flip side, if blood glucose levels are too low, glucagon is secreted and is responsible for converting stored glycogen into glucose which are then secreted into the blood, thus increasing blood glucose levels.

how is the process of photosynthesis taking place thru Calvin Cycle?
This is the ideal question! Thanks for asking!
Before we start, let's go through a mini-review.
Photosynthesis:
The complex process by which carbon dioxide, water, and certain inorganic salts are converted into carbohydrates by green plants, algae, and certain bacteria, using energy from the sun and chlorophyll.
Calvin Cycle:
A series of biochemical reactions that take place in the stroma of chloroplast in photosynthetic organisms.
Now that we have gone through what these two terms are and their definitions, let's head onto the actual questions.
So the question asks, how is the process of photosynthesis taking place through Calvin Cycle?
In plants, carbon dioxide (CO2[tex]CO2[/tex]CO2C, O, start subscript, 2, end subscript) enters the interior of a leaf via pores called stomata and diffuses into the stroma of the chloroplast—the site of the Calvin cycle reactions, where sugar is synthesized. Because they are not primarily fueled by light, these reactions are often known as the "light-independent reactions."
Carbon atoms from CO2 [tex]CO2[/tex] CO2 C, O, start subscript, 2, and end subscript are fixed (incorporated into organic molecules) and utilized to create three-carbon sugars in the Calvin cycle. ATP and NADPH produced by the light reactions are used to power and support this activity. Calvin cycle reactions occur in the stroma, as opposed to light reactions, which occur in the thylakoid membrane (the inner space of chloroplasts).
