They were all once living things. However, due to evolution, these have all adapted in many ways, or become extinct.

I hope this helps.

While biodiversity includes the number of species in a given area, it also includes phylogenetic lineages.

<h3>What is biodiversity, exactly?</h3>

The variety of animals, plants, fungi, and even microorganisms like bacteria that make up our natural environment are all included in what is known as biodiversity. These various species and critters collaborate in complicated web-like ecosystems to keep things in balance and support life.

<h3>What kind of biodiversity is that?</h3>

As a group of distinctive living entities having the capacity to reproduce with one another, biodiversity. Blue whales, white-tailed deer, white pine trees, sunflowers, and minuscule germs that are even too small to be seen with the eye are a few examples of species.

<h3>How can biodiversity be preserved?</h3>

Purchasing fewer products and ensuring that the ones you do purchase have a minimal impact on biodiversity investing in initiatives to advance biodiversity.

Match the following:Part A1. Transverse foramina present.2. No canals or foramen present. It articulates superiorly with the sac

Stels [109]

Answer:

1. Transverse foramina present: Cervical

2. No canals or foramen present. It articulates superiorly with the sacrum: Coccyx

3. Receive the most stress: Lumbar

4. Attach to ribs: Thoracic

5. Articulates with hip bones of the pelvis: Sacrum

Explanation:

The vertebral column is a series of 33 bones called vertebrae that play a key role in organ protection, movement of body, and overall support. The column has been divided into 5 different regions with the number of bones.

1. Cervical Vertebrate: These are the group of seven vertebrae of the neck, start immediately below the skull. Two cervical bones C1 and C2 are unique in function. They are responsible for the movement of the head. They have transverse foramina which gives passage to vertebral artery and vein.

2. Thoracic Vertebrae: They are a group of twelve small bones that form the vertebral spine in the upper trunk. The function of the thoracic vertebrae is to articulate with ribs to produce the bony thorax.

3. Lumbar Vertebrae: This is the largest segment of the vertebral column that consists of 5 bones between the rib cage and pelvis. They carry all of the upper body weight providing flexibility and movement to the trunk region. This is why it can receive the most stress easily.

4. Sacrum Vertebrae: There are 5 sacral vertebral fused bones. It connects to the hip bones and play role in forming a strong pelvis.

5. coccyx Vertebrae: These are a group of 4 fused bone. There is no vertebral canal due to a lack of vertebral arches. They provide an attachment site for muscles ligament and tendons. They also play a role in stabilization and support while sitting.

Answer:

According to the diagram, what is occurring in step 7 is cytokinesis, with the separation of two daughter cells, following cell division.

Explanation:

Cytokinesis is a process that occurs at the end of mitosis or meiosis, being the final step of cell division. This mechanism allows the separation of the two daughter cells, with equal distribution of cytoplasm and formation of cell membrane, differentiating into two independent cells.

In the diagram it can be observed (step 7) that after the division process —in yellow— two arrows pointing to two cells are evident, which implies the process of cytokinesis.

Prior to the cytokinesis process, karyokinesis occurs, which is the separation of nuclei and formation of the nuclear membrane.

In animal cells, karyocinesis occurs by the effect of a ring of actin and myosin that helps to force the separation. In the plant cell, the fragmoplast is formed, a septum that induces the separation of the daughter cells.

The other options are not correct because:

Cell growth occurs in G1 phase.
Cell preparation occurs in interphase.
DNA replication occurs in S phase.
Mitosis is represented in yellow, and involves 4 phases.

"In proteins, structural segments called ____ provide flexibility that allow parts of the protein to bend, fold, or move."

Rainbow [258]

Answer:

The correct answer is "random coils".

Explanation:

Random coil is a type of polypeptide secondary structure comprised of conformation that do not follow an established conformation but rather are oriented randomly. These random coils conformations provides flexibility to proteins, since the lack of a particular structure (such as alpha helices or beta sheets), allows the protein to bend, fold or move.
