surfaces curving inward, so it makes parallel light rays curve outward or diverge. That's why concave lenses are sometimes called diverging lenses. ... The distance from the center of the lens to the focal point is, again, the focal length of the lens.

Classify the following organisms into their respective kingdoms
Minchanka [31]

Answer:

  1. Yeast - Fungi
  2. Penicillium - Fungi
  3. Rhizobium - Monera
  4. mushroom - Fungi
  5. Amoeba - Protozoan
  6. fish - Animalia

Explanation:

The Fungi Kingdom is a kingdom composed, as the name says, of fungi, which are organisms represented by many species, among them: yeasts, mushrooms, molds, Penicillium and others. As you already know, fungi are eukaryotic and multicellular organisms (with the exception of yeasts).

The monera kingdom is the kingdom formed by bacteria and also has several species as members. Among these species we can mention the Lactobacilli, Escherichia coli, Rhizobium (nitrogen-nodulating bacteria, very important for the natural fixation of nitrogen in legumes), among others.

The kingdom of protozoa is very diverse and even has an organism that does not have any type of genetic, structural and morphological similarity, but in most cases, the members of this kingdom are heterotrophs, eukaryotic and unicellular organisms. An example of this is amoebas.

The animal kingdom is made up of all animals, the most diverse and populous kingdom. All animals belong to that kingdom, including fish.

Choose the event below that does not occur during apoptosis Choose the event below that does not occur during apoptosis rupture
dedylja [7]

Answer:

Rupture of the cell, releasing cytoplasmic contents.

Explanation:

Rupture of the cell to release the cell content into the intercellular space occurs in necrosis. This event does not occur in apoptosis. Release of the cell content into the intercellular space in necrosis results in stimulation of inflammatory response. Apoptosis does not include inflammatory reaction and hence, the cells do not rupture to release their content.

How are structure and function related to adaptation?
Shkiper50 [21]
Adaptations are the result of evolution in different living organisms. This process occurs amazingly through gene mutation but it takes a very long period in time. Adaptation processes occur to help species survive and thrive in the ecological balance of life. Structural adaptations are physical features of an organism that adapted through time. An example of this are the bills of a bird and the fur of bears that they generally need for their survival; birds for hunting, and bears to protect them from low climate areas.
<span>
Functional or Behavioral adaptations refer to particular things that an organism or organisms do to survive. In the example above, behavioral adaptations that birds do is through certain bird calls and migration, while bears hunt during warmer seasons and hibernate during winter season. </span>
