- The illustration is a representation of the different ways molecules are transported across a cell membrane, that represents active transport is IV.
- Active Transport is described as a process that involves the movement of molecules against a gradient or an obstruction from a location of lower concentration to a region of greater concentration.
- A protein pump uses ATP, which is a form of stored energy, to move molecules during active transport.The process of active transport, which moves molecules using ATP as an external energy source.
- Some examples of active transport include the absorption of glucose in the human intestine and the uptake of minerals or ions into the root hair cells of plants.
- Active transportation comes in two flavors:
- Primary active transport
- Secondary active transport.

<span>The appropriate response is A. Lamarck is best known for his Theory of Inheritance of Acquired Characteristics, first exhibited in 1801. In the event that a life form changes amid life with a specific end goal to adjust to its condition, those progressions are passed on to its posterity.</span>
Answer:
within the cartilage divide and secrete new matrix
Explanation:
Chondroblasts also called as perichondrial cells form chondrocytes which are the cells of cartilage. They also secrete the cartilage matrix which forms the cartilage. This matrix consists of collagen, fibers, proteoglycans, hyaluronic acid, water and glycoproteins.
They divide within the formed cartilage too to secrete new matrix. They are called chondrocytes when they become a part of cartilage matrix. Here they grow the cartilage matrix by secreting more extracellular matrix rather than dividing. Once the cartilage formation is completed it is composed 10-20% of collagen fibers, 65-80% of water and rest is made by proteoglycan-hyaluronic acid aggregates.
Answer:
RNA is Ribonucleic acid
mRNA
rRNA
tRNA,
Explanation:
mRNA, or messenger RNA, that serve as temporary copies of the information found in DNA; rRNA, or ribosomal RNA, that serve as structural components of protein-making structures known as ribosomes; and finally, tRNA, or transfer RNA, that ferry amino acids to the ribosome to be assembled
