Biology

Answer:

DNA packaging contributes to the compaction of the genetic material into cells that are many times smaller and also regulates gene expression and cell replication in living systems.

Explanation:

DNA is a fundamental molecule that contains instructions that make each organism unique. Each chromosome is composed of a very long linear DNA molecule associated with histone proteins that compact the genetic material, which is known as DNA packaging. Transcription and replication require that both strands of the DNA separate. Nonetheless, during DNA packaging, nucleosomes and the folding into chromatin fibers ensure chromosomal DNA is correctly packaged inside smaller nuclei. In consequence, DNA packaging not only enables the compaction of long linear DNA into the cells but also is involved in key biological processes such as gene regulation (transcription) and cell replication.

Usimov [2.4K]

The question is incomplete as it does not have the options which are:

A. Phloem

B. Xylem

C. Apical meristem

D. Root cap

Answer:

The correct answer will be option- Root cap

Explanation:

The plant growth takes place not only above the surface but below the surface also in the roots. Roots continually grow to absorb more water and nutrients to support the growth of the plant.

The roots are protected by a layer of protective cells forming a structure called root cap below the root. The root cap protects the roots, secretes a substance which helps the growth of the root and the sense gravity.

In the given question since the roots are not able to grow therefore the damaged part will be the root cap.

Thus, the root cap is the correct answer.

The coracobrachialis muscle originates on the __________.
Travka [436]

Answer:

Option C, coracoid process of the scapula

Explanation:

Coracobrachialis muscle is one of the essential muscles that is responsible for the movement of elbow along with biceps brachii and triceps muscles.  

The coracobrachialis arises from the coracoid process of the scapula. It assists the elbow in flexion and internal rotation. Musculocutaneous nerve passes through the Coracobrachialis muscle and terminates at the lateral end of the cutaneous nerve of the forearm. However, the Coracobrachialis terminates at the humerus and its medial surface

Hence, option C is correct

Como aseguramos que en la mitosis la nueva célula es idéntica a la célula madre ?!!!
lozanna [386]

Answer:

The daughter cells are genetically identical because mitosis is a process that ensures the equal distribution of the replicated genetic material between these cells

Explanation:

During mitosis, the DNA is duplicated during the interphase (S-phase). Subsequently, the replicated chromosomes are arranged in the center of the parent cell (metaphase) to be finally separated and equally distributed between the daughter cells.
