The right option is; dark-field microscope
A light microscope that makes the specimen appear light on a dark background is called a dark field microscope.
Dark field microscopes are light microscopes that are used in different ways to clearly view various specimens that are unstained, transparent, and hard to see using a light field unit. Dark field microscopes are very effective because they show the details of unstained and live samples. It is also very simple to use, and inexpensive to set up.
Answer:
C) dwarf mistletoes, which parasitize particular species of forest tree
Explanation:
Uniform dispersion is observed in plant species that inhibit the growth of nearby individuals. For example, the sage plant, salvia leucophylla, secretes toxins, a phenomenon called negative allelopathy. Animals that maintain defined territories, such as nesting penguins, also exhibit uniform dispersion.
In lodgepole pine stands, spread of dwarf mistletoe into young trees is more extensive from single, isolated residual trees than from relatively uniform, dense, even-aged stands of residual trees.

The correct answers are sex hormones and thyroid hormones.
<h3>Hormones</h3>
In multicellular animals, a hormone is any member of a class of signaling molecules that is carried by complex biological mechanisms to distant organs to control physiology and behavior. The proper development of fungi, plants, and animals depends on hormones. The broad definition of a hormone (a signaling molecule that functions beyond from its point of production) allows for the classification of a wide range of molecular classes as hormones. Eicosanoids (such as prostaglandins and thromboxanes), steroids (such as oestrogen and brassinosteroid), amino acid derivatives (such as epinephrine and auxin), protein/peptides (such as insulin and CLE peptides), and gases are among the substances that can be termed hormones (e.g. ethylene and nitric oxide).

You find a 10,000,000 year old rock 2,500 km away from the
nearest seafloor spreading center. The plate has been moving since its
formation by (2,500 km)(100,000 cm/1 km)/(10,000,000 yr).so the plat has been
moving equal to 25 cm per year since its formation.
