How long does the average tree live?
Known to live over 1000 years of age however,it does depend on the tree and how it is treated!
How does fossils size relate to faunal succession?
The size of fossils can be used to help determine the relative age of rock layers in faunal succession. Generally, smaller and simpler organisms are found in older rock layers, while larger and more complex organisms are found in younger rock layers. This principle is known as the Law of Faunal Succession.
What is the largest order of marsupials?
The largest order of marsupials is the Diprotodontia and it consists of about 137 species in 13 families. Diprotodontia include:
Gumnuts come from eucalyptus trees, which are also known as gum trees.
What plant wraps itself around a tree and makes the tree suffocate?
No. As a general rule, koalas are nocturnal, meaning they are most active at night. They are, however, often seen grazing during the day, and they will move between their home trees during both the day and the night.
How many chromosomes are in a body cell of a eucalyptus tree?
A eucalyptus tree typically has 2n = 22 chromosomes in each body cell.
What is the meaning up a gum tree?
A gum tree usually refers to eucalyptus trees that are native to Australia. These trees are known for their aromatic leaves and smooth bark. In Australian culture, the gum tree is a symbol of resilience and strength.
How do koalas bath themselves?
Koalas typically groom themselves by licking their fur with their coarse tongues. They may also rub their bodies against tree trunks to help remove dirt and debris from their fur. Rain can also help koalas to wash themselves.
How would you answer scientists who say locomotion is a necessary characteristics of a animal?
While locomotion is a common characteristic of animals, there are exceptions such as sponges or barnacles that are sessile. These organisms have evolved unique feeding strategies to compensate for their lack of movement, showcasing the diversity of adaptations in the animal kingdom. Therefore, while locomotion is prevalent in many animals, it is not an essential characteristic for all.
What kind of body symmetry does a koala have?
Penguins, like all vertebrates, have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
Classification of bacteria based on temperature?
bacteria r of 3 types accd to temperature
psychrophilic
mesophilic
thermophilic
they may b also gram + and gram -
enzyme activity depends on the temperature of the environment, and microorganisms are classified in three groups according to their temperature preferences: psychrophilicorganisms (psychrophiles) prefer cold temperatures of about 0°C to 20°C; mesophilic organisms (mesophiles) prefer temperatures at 20°C to 40°C; thermophilic organisms (thermophiles) prefer temperatures higher than 40°C (Figure 1 ). A minimum and a maximum growth temperature range exist for each species. The temperature at which best growth occurs is the optimum growth temperature.
Are bears carnivores or omnivores?
Bears eat meat, and berries. Although bears are often classified as carnivores, most bear species are classical anatomical omnivores.
Where does the word zoology come from?
The word anime is an abbreviated pronunciation in Japanese of "animation"
What does man use gum trees for?
It is a fast-growing source of wood, its oil can be used for cleaning and functions as a natural insecticide, and it is sometimes used to drain swamps and thereby reduce malaria risk (Good tree for draining as they use/need a lot of water)
What are structural characteristics of koalas?
Koalas are four-legged warm-blooded vertebrates. They are mammals; specifically, they are marsupials. As with all marsupials, the koala has a pouch, where the joey stays after birth for up to ten months. When the joey leaves the pouch, it stays for several more months on the back of their mother. The pouch opens backwards.
Koalas have very strong claws suitable for gripping trees and climbing. Between their first and second "fingers" is a large gap, which enables them to also grip tree branches comfortably, whilst their hind legs have one toe set at a wide angle. They also have toes with thick pads which enable them to sit comfortably in a tree all day.
In order to attract a mate, the male has a scent gland which emits a very strong scent.
Koalas in southern regions have thick, wool-like waterproof fur to keep them warm in cold weather and dry in rain. Koalas in northern regions are smaller, with less dense fur.
What is a natural disaster in the habitat of koala bears?
A common natural disaster in the habitat of koalas (which are not bears) is bushfires. Bushfires rage through koala habitats, burning eucalyptus trees and undergrowth, and therefore posing a severe threat to the survival of koalas.
Like all mammals, koalas are vertebrates because they have a spine and internal skeleton.
Mammals, birds, fish, reptiles and amphibians are all vertebrates.
What are the classification levels of a koala?
The classification levels of the koala are:
DOMAIN: Eukarya
KINGDOM: Animalia
PHYLUM: Chordata
CLASS: Mammalia
INFRACLASS: Marsupialia
ORDER: Diprotodonta
FAMILY: Phascolarctidae
GENUS SPECIES: Phascolarctos(leather-pouched bear) cinereus (ash-color)
Do fishers hibernate in the winter?
No, fishers do not hibernate in the winter. They are active year-round, although their activity may be less during the winter months due to the colder weather and reduced food availability. Fishers are skilled hunters and can adjust their behavior to survive in different seasons.
Why does it get colder as you go up in elevation?
There are two major effects. There are a lot of other things going on, but these dominate.
One is that the sun mostly heats the ground, not the air, but the atmosphere is strongly cooled by direct radiation to space. So for the air at a certain level to be warmed it required vertical movement of air warmed by contact with the surface.
But when a chunk of air rises its pressure decreases and it experiences cooling from expansion (the opposite of heating by compression.)
Why do vital organ functions slow down during hypothermia?
Because your body has to conserve its energy to use for keeping itself warm, it will shut down any functions that are not absolutely vital to life, and slow down those that are vital. Because there's not enough blood in in your body to keep you warm enough: hence slowing your vital organs down.
How is ventilation controlled in response to changing demands on the body?
Ventilation is a process humans rely on to maintain high oxygen and low carbon dioxide concentrations at the gas exchange surface. The process that ventilates lungs is breathing. Humans ventilate the lung by negative pressure breathing
