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

Svetllana [295]

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.

A man who heavily smokes has developed lung cancer. The tobacco smoke has caused mutations in some of the cells in his lungs, ma

nexus9112 [7]

Answer:

If he inherited a mutation which made him more susceptible to lung cancer, it may have been present in some of the gametes he produced and passed to his children

Explanation:

Even tho the cause of lung cancer is not very clear, a genetic predisposition is of a great influence, his smoking and therefore causing a lung cancer is not appliable to his children because of no connection, but in the sense of having a mutation which makes you predisposable to the cancer with or without the smoking, can lead to a high risk of gene inheritance and therefore inheriting the mutation with a high risk of getting lung cancer excluding the smoking.

Global warming is the increase in Earth's average temperature over a long period of time.

<h3>GLOBAL WARMING:</h3>

Global warming is a cause for concern in our world today. It is a phenomenon whereby the temperature of the Earth atmosphere increases over a period of time.

Global warming is caused by the release of greenhouse gases into the atmosphere. Greenhouse gases are capable of trapping and releasing heat into the Earth.

Greenhouse gases include; carbon dioxide ((CO2), methane, sulfur dioxide (SO2) etc.

Therefore, global warming is the increase in Earth's average temperature over a long period of time.

Please place the following vessels in the correct order to represent the arterial circulation leading up to the glomerulus.

Ymorist [56]

The following vessels are connected as below:

aorta ->renal arteries ->segmental arteries ->interlobular arteries ->arcuate arteries ->cortical radiata ->afferent arteries ->glomerulus.

1) aorta : arises from heart which carry blood from heart to the rest of the body

2) renal artery :it arises from the aorta which carry blood to kidney .it carry unfiltered blood .

3)segmental arteries : it arises from renal artery .it has 5 branches or segments.

4)interlobular arteries : it arises from segmental arteries. the interlobular arteries pass directly outward between the medullary rays to reach the fibrous tunic ,where they end in the capillary network of this part.

5)Arcuate arteries: it arises from interlobular arteries .it is also known as arciform arteries, are vessels of the renal circulation. they are located at the border of the renal cortex and renal medulla.

6) cortical radiata: it arises from arcuate arteries.

7) afferent arteries: it arises from interlobular arteries and also connects to glomerulus. they are a group of blood vessels that supply the nephrons in many excretory systems .they play a important role in regulation of blood vessels.

8) glomerulus : it connects from afferent arteries.it is the filtering unit of kidney ,is a specialised bundle of capillaries that are uniquely situated between two resistance vessels.

Disclaimer: the given question is incomplete means it contains incomplete data .the correct question is given below.

Question: Please Place The Following Vessels In The Correct Order To Represent The Arterial Circulation Leading Up To The Glomerulus. Aorta Interlobar Artery Segmental Artery Afferent Arteriole Cortical Radiate Renal Artery Arcuate Artery Glomerulus

Please place the following vessels in the correct order to represent the arterial circulation leading up to the glomerulus.

Aorta

Interlobar artery

Segmental artery

What happens to contraction of a muscle cell if some of the Ca2+ that was released during a contraction is still in the cytoplas

Kazeer [188]

<h2>Muscle contraction in cytoplasm </h2>

Explanation:

Calcium stays in the sarcoplasmic reticulum until discharged by an improvement. Calcium at that point ties to troponin, causing the troponin to change shape and expel the tropomyosin from the coupling destinations. Cross-connect stick proceeds until the calcium particles and ATP are never again accessible.
ATP is basic to get ready myosin for official and to "revive" the myosin.
When the actin-restricting destinations are revealed, the high-vitality myosin head overcomes any issues, framing a cross-connect. When myosin ties to the actin, the Pi is discharged, and the myosin experiences a conformational change to a lower vitality state. As myosin consumes the vitality, it travels through the "power stroke," pulling the actin fiber toward the M-line.
