Giraffes

Giraffes are well known for their extraordinarily long necks which they use to eat the leaves on tall trees.

2,117 Questions

Structures with no function that are remnants of an organisms evolutionary past are?

Vestigial structures are anatomical features that have lost their original function in the course of evolution. These structures are a result of changes in the organism's environment or behavior, rendering them unnecessary. Examples in humans include the appendix and wisdom teeth.

What example of evolution is in a long neck giraffe?

The long neck of giraffes is an example of evolution through natural selection. Giraffes with longer necks were able to reach higher leaves for food, giving them a survival advantage. Over time, due to this advantageous trait being passed down to offspring, giraffes with longer necks became more prevalent in the population.

What are the horns on a giraffe for?

Fighting. The males use their long necks to swing as hard as they can and strike the other male in the neck with the horns. It is usually done in competition for mating with the females.
Some believe the horns are cooling towers and release heat, and others think that it's just a way to protect their heads.

Which of Mendels principles explain why the offspring is albino?

The principle of dominance and recessiveness explains why the offspring is albino. Albinism is a recessive trait, meaning that both parents must carry at least one copy of the albino gene in order for it to be expressed in the offspring. This demonstrates how traits can be masked in one generation and expressed in the next through Mendelian genetics.

During a study session about evolution one of your fellow students remarks The giraffe stretched its neck while reaching for higher leaves its offspring inherited longer necks as a result Which?

Characteristics acquired during an organism's life are generally not passed on through genes. Just because giraffes stretch their neck doesn't mean they will get longer.

Good luck!

Do giraffes live on the Savannah?

Yes, giraffes are common inhabitants of the savannah biome. They thrive in open grasslands with scattered trees, which are characteristic of savannah environments. Giraffes use their height to feed on leaves and buds from tall trees in the savannah.

What are anaerobic heterotrophs?

A photoautotroph is when an organism is able to create its own food from sunlight. Photo means light and troph refers to the word "feeder". When the word is broken down it is much easier to understand.

Autotroph is to heterotroph as phytoplankton is to what?

Zooplankton. Phytoplankton are autotrophs, as they produce their own food through photosynthesis. Zooplankton are heterotrophs, relying on consuming other organisms, like phytoplankton, to obtain their energy.

ARe humans heterotroph or autotroph?

Humans are heterotrophs, which means they rely on consuming organic compounds from other organisms to obtain their energy and nutrients for survival. Autotrophs, on the other hand, are organisms that can produce their own food through processes such as photosynthesis.

Does the giraffe have bigger cells than a bacteria or just more of them?

Girrafe is an eukaryotic organism while bacteria is procaryotic. As we know that eukaryotic organism has larger cells than prokaryotic organism so girrafe has larger cells than a bacterium.

What is nervous system of a giraffe?

A giraffe's nervous system includes a brain, spinal cord, and peripheral nerves that aid in coordinating movement, sensation, and adapting to the environment. Their long neck houses specialized nerves that help regulate blood pressure and maintain balance, allowing them to stand tall and reach high branches for food. The giraffe's nervous system also plays a crucial role in their unique behaviors, such as alertness to predators and social interactions with other giraffes.

What are the behavioral adaptations of a giraffe?

Nine different subspecies of giraffe are present in Africa. Each species displays the traditional long neck that makes the animal so recognizable. The giraffe is the tallest land animal on earth, standing over 18-feet tall. This physical adaptation makes the giraffe unusual in the animal kingdom. However, to survive the giraffe has also developed a number of behavioral adaptations to keep it safe and to decide which males get to mate with the females.

Drinking

A giraffe is at its most exposed to predators when it bends down for a drink. The animal must get in an awkward position with its front legs so its head can reach the water. Predators such as crocodiles and lions can take a giraffe down once in this position very easily. The giraffe has developed a behavioral adaptation to drink water, getting as much water as quickly as it can.

Necking

The long necks of the giraffe play a large role in determining dominance and mating rights among giraffes. Two male giraffes will fight in what is called necking. The giraffes will use their necks to swing their heads to land a blow on the other male giraffe. The longer necks and heavier heads tend to win these disputes. The assumption is that the neck of the giraffe is part of the sexual selection of the species and not just an adaption to reach high leaves on trees.

Groups

Female giraffes stay in groups or herds with young males, which is done to better detect predators for the entire group. Males may also live in bachelor herds for protection. Older mature males may live a solitary life. No hierarchy exists, such as a dominate female, within the herd, and giraffes can leave or enter the herd at any time.

Newborns

The most dangerous time of a giraffe's life is the few minutes after it is born. The newborn must get up and walk within a few minutes of birth to avoid predators. The mother will keep the newborn hidden for the first month. Thereafter, the calf stays within the female herd in a nursery that is watched over by all the giraffes in the herd to protect the calves.

Can a giraffe get fat?

Giraffes can become overweight in captivity if they have access to too much food and limited space to exercise. In the wild, they are less likely to become overweight due to their natural diet and lifestyle of constant movement.

How fast are girraffes in mph?

Giraffes can run at speeds of up to 35-40 miles per hour for short bursts. However, they typically maintain a more leisurely pace of around 10 miles per hour when roaming or grazing.

What are giraffes horns for?

Giraffes have ossicones, which are not true horns, but are bony outgrowths covered with skin. Ossicones serve various purposes, including protection, dominance display, and thermal regulation. They are also used in necking behavior, where males engage in combat to establish dominance or mating rights.

Is a giraffes herbivore?

yes. Their favorite leaves are from thorn acacia trees

How does the giraffe spend it's day?

Giraffes spend most of their day eating, primarily feeding on leaves, shoots, and fruits from tall trees. They can spend up to 20 hours a day eating and resting. Giraffes also socialize with other members of their herd, grooming each other and engaging in playful behavior.

Darwin and Lamarck had different ideas about why all giraffes now have long necks why?

Lamarck would have said that the ancestors of

modern-day giraffes had short necks but stretched

their necks as they tried to reach leaves in trees; so,

their descendants were born with longer necks.

Darwin would have said that in a population of

ancestral giraffes, some had slightly longer necks

than others; the long-necked giraffes were better

able to feed on tree leaves and as a result produced

more offspring. Over time, the proportion of longnecked

giraffes in the population increased.

If the egg cell of a giraffe has 31 chromosomes how many chromosomes will a giraffes heart cell have?

A giraffe's somatic cells, such as heart cells, will also have 31 chromosomes. This is because all cells in an organism's body carry the same set of chromosomes, with the exception of sex cells (gametes) which undergo meiosis to reduce their chromosome number by half.

Do all living things vomit?

No, not all living things vomit. Vomiting is a physiological response that some animals have evolved to expel harmful substances from their stomachs. Organisms like plants and certain simple organisms do not have the ability to vomit.

Why is a giraffes tongue black?

A giraffe's tongue is black to protect it from sunburn while it is out for long periods of time feeding on leaves from trees. The dark pigment in their tongues acts as a natural sunscreen to prevent them from getting injured or sunburned.

What is the only animal always born with horns thanks to ossified cartilage called ossicones which are part of the skull?

The giraffe is the only animal born with horns called ossicones. These ossicones are made of ossified cartilage and are part of the giraffe's skull structure.

How long is a giraffe's tong?

a giraffe's tongue can grow up to 3ft long

How do giraffes change their environment?

Giraffes help change their environment by eating leaves from tall trees, which helps to control the growth of vegetation and create open spaces for other species. Their browsing behavior can also promote the growth of new plants by dispersing seeds in their dung across different areas. Additionally, their presence can influence the behavior of other herbivores and shape the structure of the ecosystem.

Do giraffes migrate or hibernate?

Giraffes do not migrate or hibernate. They are known to roam over large home ranges in search of food and water, but they do not have set migration patterns like some other animals. Additionally, because they live in warm climates, they do not need to hibernate during the winter.
