What is it about the life-cycle that makes cane toad populations successful?

Answers

Life-cycle - Cane Toad Population Successful

The water of any nature is essential for survival and reproduction. Cane toad can produce eggs ranges from 8,000 to 35,000 at a time. There are two conditions for healthy development which are described as follows:

  • The slow flowing water must be avaible for the toad.
  • 25-30 degree C temperature is needed for healthy development.

In this way, cane toads make population successful during the life cycle.

Cane Toads are very strong and adaptable, they are also poisonous throughout its life cycle, which is why they only have a few predators and have a life span of 10-15 years. Cane toads have poison glands, and the tadpoles are extremely toxic to most animals if consumed. They are productive breeders, they only need a small pool of water of almost any nature. The female cane toads can lay 8,000 to 35,000 eggs at a time and may produce two clutches in one year. The eggs will hatch within 24-72 hours and the tadpole stage may last from three to twenty weeks. Cane toads in the tropics grow really quick and may be sexually mature only within one year. Cane toads have been introduced to many regions of the Pacific and the Caribbean islands as a method of agricultural pest control because of their ravenous appetite, however, they are now considered pests and are dangerous to humans and animals, both wild and domesticated especially to dogs.

Which of earth layers has the same chemical composition as the mesosphere

Answers

Answer:

astenosphere

Explanation:

The mesosphere and the astenosphere are both part of the mantle. The mesosphere is the deeper part, while the astenosphere is the outer part of the mantle. Both of these layers have the same chemical composition, but the temperature and pressure are different in them. The mesosphere has higher temperature and pressure, so even though it is very hot, the rock is actually solid. The astenosphere has lower temperature and pressure, so the rock is more liquid.

Answer:

astenosphere

PLEASE HELP!!!!! Explain how infection might spread, how people fight off diseases, and why malnutrition can lead to the spread of disease in the time immediately following a natural disaster.

Answers

Answer:

When people are unable to access their homes due to a natural disaster, a(n)  

✔ shelter-in-place plan

advises them where to stay.

To lessen the likelihood of a wildfire spreading, a(n)  

✔ containment plan

might be enacted.

A(n)  

✔ evacuation plan

explains what people should do immediately following a disaster.

Explanation:
Infections spreading:
Infections are caused by bacteria, virus and other microscopic organisms. They spread through droplet (sneezing etc), they can spread through blood contact (used needles that are re-used), direct physical contact (skin infections), stool (germs from excretion) and contaminated objects.

How people fight off disease:
We have antibodies in us that fight off invading cells that contain foreign bodies. Our immune system secretes these antibodies and these antibodies will fight off the infection. The time it takes for the infection to be eradicated depends on the strength of your immune system and whether you have been vaccinated.

Natural disaster:
Natural disaster such a tsunami's and earthquakes can contaminate water supplies. In tsunami's the water from the sea will go into the drinking water which isn't safe because it could cause diseases such as cholera to spread. Earthquakes disrupt sewage structures. If these are broken, water regulation would not be as good so we end up drinking dirty water, which could also be contaminated with cholera!
