Answer:

perform functions that tissues cannot carry out on their own

Explanation:

In the hierarchy of living system organs come after tissues and before organ systems. Hence, organs are complex then tissues and perform functions that tissues wont be able to perform on their own.

A organ is made up of various types of tissues. They can be divided into two categories, main tissue and sporadic tissue. Main tissue or parenchyma is unique to that organ and defines the function of the organ. For example: Cortex and medulla together form the main functional tissue in kidney. Similarly, myocardium is the main tissue of the heart. Sporadic tissue has blood vessels, nerves and connective tissues.

ycow [4]

Answer:

Cardiac muscle tissue

Explanation:

Myocardium or heart muscle is a special type of muscle (differ than striated and smooth) and it is the main tissue of the walls of the heart.

Heart muscle consists of individual heart muscle cells (cardiomyocytes) which are joined together by intercalated discs. It also contains  collagen fibres and other substances that form the extracellular matrix.

Heart muscle has a "special" mode of contraction: action potential triggers the release of calcium ions from the cell's internal store, the sarcoplasmic reticulum.

It is believed that weed killers like 2,4-D and 2,4,5-T may
goldfiish [28.3K]

Herbicides are a broad category of pesticides that are used to get rid of undesirable plants like weeds and grasses that hinder the development and productivity of desired agricultural crops. Both 2,4-D and 2,4,5T are also known as 2,4-Dichlorophenoxyacetic acid and

  • Herbicides like 2,4-D and 2,4,5-T are also referred to as auxin-type herbicides or plant growth regulators. Auxins are hormones that affect cell division and elongation in order to control cell growth.
  • Auxins are required by plant cells in the proper concentration for growth and development. If auxin levels are too low, plant growth is not promoted at all, and if levels are too high, plant growth is excessively stimulated.
  • Most grasses are not killed by 2,4-D and 2,4,5 T, but broadleaf weeds are. It moves to the plant's meristems after being absorbed through the leaves.
  • These herbicides affect the tissues' cells, causing them to continually divide and proliferate. The plant finally dies as a result of this unchecked, unsustainable growth, which also causes stem curling and withering of the leaves.

Thus, by promoting cell division, these compounds act as herbicides.
