Answer:a) Where is the plasma membrane located on an animal cell? 

Explanation:

Answer:

Carbon dioxide and energy from the Sun is converted into sugar molecules(glucose)  and oxygen; ATP molecule

Explanation:

The deamination of cytosine, resulting in the formation of uracil, leads to a transition during DNA replication.

Deamination is a process where an amino group is removed from a nucleotide base, altering its chemical structure. In this case, cytosine undergoes deamination and is converted to uracil. During DNA replication, uracil pairs with adenine instead of guanine, which would have been the pairing in the case of cytosine. This forms a U:A base pair instead of the original C:G base pair.

A transition refers to a nucleotide substitution where one purine base (adenine or guanine) is replaced by another purine base, or one pyrimidine base (cytosine or thymine) is replaced by another pyrimidine base. In this scenario, the deamination of cytosine to uracil results in a pyrimidine-to-pyrimidine transition (C to U) since both cytosine and uracil are pyrimidine bases.

The functions of the erector spinae muscles include extension, flexion, lateral flexion, and rotation of the spine.

The erector spinae muscles are a group of muscles located in the back. They consist of three main muscles: the iliocostalis, longissimus, and spinalis. These muscles play a crucial role in maintaining posture and facilitating movement.

One of the primary functions of the erector spinae muscles is extension of the spine. They help us stand upright and maintain an erect posture. When these muscles contract, they pull the spine backward, allowing us to extend our back.

The erector spinae muscles also assist in flexion of the spine. When we bend forward, these muscles contract to help us flex our spine and bring our torso closer to our legs.

In addition to extension and flexion, the erector spinae muscles enable lateral flexion of the spine. This means they allow us to bend our torso sideways, facilitating movements such as side bending.

Furthermore, the erector spinae muscles contribute to the rotation of the spine. They allow us to twist our torso, enabling movements like turning our upper body to the left or right.

Overall, the erector spinae muscles provide stability and support to the spine, enabling us to perform various movements and maintain proper posture.

The erector spinae muscles play a crucial role in the movement and stabilization of the spine.

They are a group of muscles located on either side of the vertebral column, extending from the base of the skull down to the pelvis. The functions of the erector spinae muscles include:

Spinal Extension: The primary function of the erector spinae muscles is to extend the spine, allowing you to stand upright and maintain an erect posture. These muscles work together to counteract the forward bending (flexion) of the spine and promote extension.

Spinal Flexion: While their primary function is extension, the erector spinae muscles also contribute to spinal flexion, especially in the lower back region. They control the movement of the spine during forward bending, such as during activities like bending down to pick something up.

Spinal Lateral Flexion: The erector spinae muscles also assist in the lateral flexion of the spine, allowing you to bend or tilt sideways. When one side of the erector spinae muscles contracts more than the other, it results in lateral bending or side-to-side movements.

Spinal Rotation: The erector spinae muscles provide some rotational control of the spine. They assist in rotating the torso to the left or right, helping with movements like twisting or turning the upper body.

Postural Support: These muscles contribute to maintaining proper posture and spinal alignment. They work to stabilize the spine and prevent excessive movement or misalignment during various activities, including sitting, standing, and lifting objects.

Core Stability: The erector spinae muscles are part of the deep core muscles, along with the abdominal muscles, pelvic floor muscles, and other muscles of the trunk. Together, these muscles provide stability and support to the spine and help transfer forces between the upper and lower body.

Overall, the erector spinae muscles are vital for maintaining proper spinal alignment, supporting posture, and facilitating various movements of the spine, including extension, flexion, lateral flexion, and rotation.

                                           The Rock Cycle

                                      by _________________

The rock cycle is a process in which rocks are continuously transformed between the three rock types igneous, sedimentary and metamorphic .Conversion to metamorphic rocks requires conditions of increased temperature and/or increased pressure, conversion to sedimentary rocks occurs via the intermediate stage of sediments, and conversion to igneous rocks occurs via the intermediate stage of magma. Increased temperature and pressure occurs in subduction zones and in areas where two plates of continental lithosphere collide to produce a mountain range, while increased pressure without increased temperature is produced when sedimentary rocks are deeply buried under more sediments. Sediments are produced when rocks are uplifted, weathered and eroded, and the resulting detrital material deposited in marine or terrestrial basins. If the sediments are buried under further layers of sediment, they can become lithified to produce a sedimentary rock. Magma is produced when rocks are melted. This melting can occur when a lithospheric plate descends into the Earth’s crust at a subduction zone, or when a mid-ocean ridge opens up and produces decompression melting in the athenosphere under the ridge. When the magma solidifies, it becomes an igneous rock.

The rock cycle has many alternative pathways. The following diagram illustrates one of these and gives an indication of the plate tectonic setting where it occurs:
