   The courtship between a male and a female elephant is short lived. They will rub their bodies on each other and even wrap trunks. The females tend to run away from the males and he will have to pursue her. The older males that are from 40 to 50 years of age are the most likely to breed with the female.

grass

Image result for grass asexualy reproduction

Grasses may reproduce sexually by seed sexual reproduction, or asexually via vegetative 
propagation tillers which arise from adventitious buds on culm nodes, rhizomes, and stolons. This section deals only with sexual reproduction involving flowers, pollination, and seeds.


whip tail lizard

The lizard is a female-only species that reproduces by producing an egg through parthenogenesis. Despite reproducing asexually, and being an all-female species, the whip tail still engages in mating behavior with other females of its own species, giving rise to the common nickname "lesbian lizards".

zebra shark


 A female zebra shark in an Australian aquarium has astounded scientists by producing live offspring asexually, three years after being separated from her long-term mate It is only the third documented case of a vertebrate of any species switching its reproductive strategy from sexual to asexual.

                                    internal fertilization
lizard


The lizard uses internal fertilization by connecting the male and female together and having a sexual connection to release the Sperm into the female's body. The Lizard is usually born in the summer time and could take up to three months for the eggs to hatch.

           rattle snake

Snakes carry their reproductive organs internally, but otherwise their anatomy falls in line with that other vertebrates. Snakes practice internal fertilization, and they lay eggs or bring forth living young sometime later.

                            external fertilization

lung fish


The larvae have long, bright red, tuft like or fan like external gills, which they use for breathing until the lungs are fully developed. The Australian lungfish lays gelatinous eggs among water plants; the larvae, which have no external gills, breathe through internal gills.

desert tree frog

A male (left) and female (right) fanged frog sit on a large leaf. This process usually occurs through external fertilization, where the female releases her eggs from her body into water. Then, the male releases his sperm to fertilize them. However, a few species of frog use internal fertilization.

                                    Fennec Fox 

structure

 Fennec fox structure is here big ears to keep them cool in the desert another structure is long thick hair to keep them hot in a cold night and from sunburns in the day.

locomotion

Fennec fox use four legs to dig a hole and Wait for pray. 

Reproduction 

Fennec foxes  give birth to one litter of pups per year, with between two and five young in a litter.

                            Elephant
structure 
Elephant have a  long trunk and have big ears

locomotion

Locomotion. Since African Elephants are one of the largest animals, they do not trot or gallop, but instead, move smoothly to faster speeds.


reproduction

Elephant female  reproduction is when the female is ready and the age they start to reproduce is at 14.

                          Scorpion
structure
The scorpion has two claws four legs and stinger.

means of defense and attack

When attacked by a predator, a scorpion can choose to use either its pincers or its venomous stinger to defend itself.

reproduction

Sexual reproduction is accomplished by the transfer of a sperm from the male to the female. Scorpions possess a complex courtship and mating ritual to effect this transfer.

                        prickly pear

Structure of the prickly pear

 Prickly pear cactus represent about a dozen species of the Opuntia genus in the North American deserts. All have flat, fleshy pads that look like large leaves. 

locomotion

There are many adaptations that the pancake prickly pear cactus has to the Sonoran Desert. Cacti have reduced their leaves to spines to reduce water loss and to protect the cactus. The roots of the prickly pear cactus are also made for very dry environment to help adapt to the deserts hot weather.


 Defence of prickly pear

Using a spinburne prickly pears can be made into livestock forage during droughts. The sticky sap  a defense against  insect predation.


Reproduction of prickly pear

To reproduce, the prickly pear cactus produces flowers. The flowers produce the red prickly pear fruit which is seedbearing. The flowers usually bloom during the spring, so that is when they climax in reproduction.

                               Barrel Cactus

Barrel Cactues structure

When young, this barrel cactus is globeshaped, elongating only after becoming about a foot in diameter. It has a long, wide, flat central spine, crosshatched with little ridges and curving downward at the end. It also has many white, bristly radial spines. Spines Red beneath a gray surface layer.


physioloogy and genetics

The barrel cactus is an important partner for lots of desert species. Not only does the plant receive pollina on from insects and seed dispersal from vertebrates, but it also hires ants to defend it against insect herbivores.




reproduction 

barrel cactus is typically propagated by seed. A mature cactus will bloom in the summer with flowers that grow in whorls around the top of the plant. To seed a cactus, plant the seeds shallowly in a cactus mix and keep them warm and very slightly moist.

                        Jumping Cholla


structure

Jumping cholla has treelike shape. It has one trunk with multiple drooping branches. Entire plant is covered with wartlike projections. 


reproduction

This plant spreads throughout the desert by its own defense mechanisms Its spines attach to anything that can carry it around, animals, people, the wind.


reproduction

The jumping cholla gets stuck on a animal or a human or falls on the ground it starts to grow roots.

scientific name

The scientific name for Darwin finches is 

Geospizinae subfamily .


adaptation

Darwin's Finches vary by what they eat because big beaks are for seeds insects small beaks are for nectar.

                  Era and Period 

   Pikaia is an extinct marine organism that lived during the Early Cambrian Period –about 530 million years ago.

                       
                    lived

                   why is it extinct because


The pikaia got extinct because  Many of the reef-building organisms died out, as well as the most primitive trilobites.

         era and period

triceratopsTriceratops is a genus of herbivorous ceratopsid dinosaur that first appeared during the late Misdirection stage of the late Cretaceous period, about 68 million years ago.


                      lived

                     general characteristics

1. long tail

2.  three horns(two big horns) (one small horn) 



                        why did it go extinct


The Triceratops, described in the latest Royal Society Biology Letters, dates to 65 million years ago, the critical period of time associated with the Cretaceous-Tertiary  extinction event that wiped out all non-avian dinosaurs and many other animals and plants

                               woolly rhinoceros

                  


                               era and period

The woolly rhinoceros is an extinct species of rhinoceros that was common throughout Europe and northern Asia during the Pleistocene epoch and survived until the end of the last glacial period.


                                        lived

woolly rhinoceros lived throughout northern Eurasia, spanning most of Europe, the Russian Plain, Siberia.



                        general characteristics

The woolly rhinoceros was a member of the Pleistocene megafauna. The woolly rhinoceros was covered with thick and long hair, which allowed it to survive in the extremely cold, harsh mammoth steppe. It also had a massive hump reaching from its shoulder. It fed mainly on herbaceous plants that grew in the steppe


                          why it got extinct

Extinction. Many species of Pleistocene megafauna, like the woolly rhinocerosbecame extinct around the same time period. Human hunting is often cited as one cause.

Mother ichthyosaur died while giving birth, scientist says. The oldest embryos of a Mesozoic marine reptile have been unearthed in China, pre-dating the previous record by ten million years, a new study says
