"When human settlers arrived on the island of Mauritus, they caused the Dodo bird species to become extinct within 50 years. What did the settlers do to cause their extinction?"

Answers

Answer 1

Answer:

It's commonly believed that the dodo went extinct because Dutch sailors ate the beast to extinction after finding that the bird was incredibly easy to catch due to the fact it had no fear of humans.

Answers

Explanation:

hi !!

here i think all areirrational expect root 36/1296,

1. root 2= root 2= 1.414213562

2. 2/root 6= root 6 /3 = 0.8164965809

3. root 36/1296=1/6=1.66666667

4. - root 6+6= -2 root 3 = -3.464101615

so, they are extended and dont have exact value so all are irrational expect no. 3 because it can be expressed in 1/6 fraction form but others will come on root form.

2. Explain the factors that led Wilson to the idea of (a) studying small islets, (b) fumigating them, and (c) observing the recolonization of species.

Answers

Answer and Explanation:

The ecologists MacArthur and Wilson took the term island biogeography theory to refer to the predictions about the number of species that could be inhabiting on an island.  

Island biogeography theory establishes that the two factors that affect species richness in natural communities on an island are the distance from the mainland and the size of the island.  

At the same time, these factors affect inmigration and extinction rates. According to the theory, islands that are closer to the continent have higher possibilities of receiving immigrants than those islands that are located farther from the mainland. This is the effect of distance.  

The effect of size is reflected in the relation between island size and species diversity. In smaller islands, the probability of extinction is higher than in bigger islands. Bigger islands can have more species than smaller ones.  

In the case of two islands of the same size and different distance to the mainland, both of them will have the same extinction rate, but the one closer to the continent will have a higher immigration rate, and so, a higher amount of species. The S value will be higher on the island closer to the continent.

Experiment:

To prove that the observations about the species richness and its relation to island size and distance to the continent were not a casualty, manipulation experiments were developed. These experiments helped to prove how the colonization process take place from cero. To observe the entire process of ecological succession and the tendencies proposed by the island biogeography theory Wilson and Simberloff (1970) eliminated the fauna on some islands to observe how they were recolonized from the continent. They fumigated the mangler island and studied these islands to account for the variation in arthropod richness over time. They studied many islands classified by distance. On each island, the richness increased at different rates.  The island closest to the continent received more immigrants and is colonized faster than the other ones, reaching its original richness faster. The farthest island was recolonized but at a much lower rate and it does not reach equilibrium while the study was going on. Although, it was expected to reach equilibrium with time.  

Scientists monitor the effects of a deadly parasite in a host. What trends will they most likely see?
A. As the parasite population increases, the host population decreases.

C. The host population decreases only if the parasite population decreases.
D. The host population will remain the same regardless of whether the parasite population increases or decreases.

I’m assuming the answer is A. As the parasite population increases, the host population decreases. Parasites often kill their host if not removed so it would make sense for that to be the answer. :)

Answers

Answer:

Although the pictorial representation is not clear but the question can be answered based on the known structure of each biomolecule. The answer is:

Carbohydrate

Explanation:

Carbohydrate is one of the four biological molecules in living systems. Carbohydrates are composed of long chains of carbon, hydrogen and oxygen in a 1:2:1 ratio i.e (CH2O)n empirical formula.

The structure of carbohydrate is composed of a ketone (C=O) or aldehyde (CHO) functional group and hydroxyll groups (OH). The simplest unit of any carbohydrate is called a monosaccharide. Hence, from the above structure in the question, which consists of long chain of carbon, hydrogen and oxygen atoms, it can be identified as a CARBOHYDRATE.

Answers

Answer: The correct answer to the question is option B

INCREASES.

As human travel increases(As humans move from one place to another),the number of introduced species likely increases because as humans move from one place to another,they introduce new species of organisms to their new environment.

These non-native species grow in this new environment,becomes economically important and doesn't pose any harm to their new ecosystem unlike invasive species that poses a substantial harm.

The number of introduced species are likely to : ( B ) Increases

As Humans migrate from one place to another they introduce new species into their new environment naturally or artificially.

Migration

The movement of humans or any type of organism comes with the introduction of new species because as they move they take along with them certain species that naturally do not belong to their new environment.

Hence we can conclude that As human travels The number of introduced species are likely to Increase.

A person is dehydration and they start to bleed from their nose. But they're bleeding from only one nostril. Why?

Answers

Dryness of the nasal mucosa.
A dry nasal mucosa causes itching and people often scratch inside the nose due to this. It damages the delicate inner lining over the nostrils. Even if one does not scratch, the capillaries present there can rupture and bleed spontaneously due to excess dryness. This happens because the nasal mucosa is very thin and fragile. In conclusion, bleeding from one nostril is caused by too much Dry air — when your nasal membranes dry out, they're more susceptible to bleeding and infections.

The lining of your nose contains many tiny blood vessels that lie close to the surface and are easily damaged.

The two most common causes of nosebleeds are:

What is nerve impulse transmission?

The nerve impulse transmission takes place between two neurons, and then in this way, from the sensory organs, the message passes to the spinal cord and the brain. The synapse is formed between the two neurons, such as the presynaptic neuron that releases the neurotransmitters, and this activates the ligand-gated channel of the postsynaptic neuron. Due to this interaction, the neurons get excited and activated.

Hence, neuron A communicates with neuron B, and the axon terminal of neuron A releases a signal that activates the receptors present on neuron B. The neurotransmitters are attached to the ligand-gated channel on neuron B.

Rima eat guava explain how the teeth tongue and sliva will help to break it down​

Answers

Answer:

Please find the role of teeth, tongue and saliva in digesting guava below

Explanation:

Digestion is generally the process of breaking down complex food substances into their simplest form. However, as easy as this sounds, there are series of processes that must take place in between to achieve the final result.

Once a food substance like guava enters the mouth (ingestion), it initially gets chewed by the TEETH in order to break it down to smaller masses that can be swallowed. During the process of chewing, the TONGUE helps to move the food around the mouth and later helps push it down the gullet/digestive tract. SALIVA, on the other hand, creates a moisturizing environment for the food to form a Bolus (round mass of food ready to pass down the esophagus). The saliva also contains an enzyme called AMYLASE that helps chemically degrade starch content of the food before passed through the digestive tract.

A Mesopotâmia e o Egito antigo foram as primeiras culturas que desenvolveram métodos de irrigação. Um dos métodos eram os canais, mas quando não funcionavam, os egípcios precisavam inventar ferramentas para bombear água do Nilo e de outras fontes. E dessa forma, desenvolveram o sistema de canais. Os governantes egípcios colocaram uma enorme importância no sistema de canais do país e os governantes regionais foram responsáveis pela escavação e reparação das estruturas. Os canais usavam a água do Nilo quando o rio estava na época da cheia e inundava algumas terras...
