Do you think it's possible for people to travel to the center of the planet? Why or why not?

Answers

Answer 1
no because the Earths cores temperature and pressure levels are extremely high, making it almost impossible for life to survive
Answer 2
No, it is not possible to travel to the earth's center which is about 6400 km. As we go below the earth's surface, the pressure and the temperature increases with depth and this we call it as the geothermal gradient (i.e change in pressure and temperature with depth), which is approximately 25° C/km

A population of birds lives on a small island. Another population of the same species lives on the mainland. The
distance between the island and the mainland is too great for birds to fly back and forth. Recently, a series of
sandbars and tiny islands have formed between the island and the mainland.

Answers

Answer:

The birds can now reach the Island.

Explanation:

The birds can now reach the Island because there is a sandbars and tiny Islands where they can rest for sometime as well as feed on the insects present at that sandbars and tiny Islands. Before these sandbars and tiny islands, the birds can't reach to the mainland due to large distance between Island and mainland so they have no capability to fly such large distance until the tiny Island and sandbars are appeared in the ocean.

why do wild plants need to reproduce sexually as well as asexually ?

Please answer correctly​

Answers

Answer:

Wild plants would need to reproduce sexually so that there can be variation throughout the species to reduce the number of plants being at risks to certain diseases if the environment is changing. However, the wild plants need to produce asexually if the environment is stable.

Wild plants need to reproduce sexually as well as asexually in order to create variation within a species and lower the number of plants that are susceptible to specific illnesses in a changing environment.

What are wild plants?

Wild plants would need to reproduce sexually. However, if the environment is stable, wild plants must reproduce asexually. Since male and female gametes are not mixed, asexual reproduction produces plants that are genetically similar to the parent plant and increases survival.

A seedling formed from a seed matures more slowly and is less robust than a cutting or bud is taken from an older plant.

Therefore, in order to diversify within a species and reduce the number of plants susceptible to specific diseases in a changing environment, wild plants must reproduce both sexually and asexually.

If you are interested in the evolutionary relationship of animals that have four limbs, which of the following would be the outgroup? Group of answer choices Sharks Ray-Finned Fish Amphibians Crocodiles Dinosaurs

Answers

Answer:

First outgroup → Ray-Finned FishesSecond outgroup → Sharks

Explanation:

The outgroup is the most distant taxonomic group that shares no traits or characters with the lineages of interest, which compose the ingroup. You can compare the outgroup with the ingroup to determine the evolutive relationship and which characters are primitive or derived.    

Even though the outgroup shares a common ancestor with the ingroup, this is placed far away in evolution, making the outgroup to be the taxonomic group less related to the other lineages. The lineages in the ingroup share another common ancestor that is more recent in history.

To select the outgroup, you need to focus on what you are interested in. There might be several outgroups, but you should choose the one that is more related or closer to the ingroups. This selection is important because you need to make comparisons to understand the evolution of specific traits.  

In the exposed example, we need to focus on animals that have four limbs. Then, we might assume that the ingroup is composed of Amphibians Crocodiles Dinosaurs. Sharks and Ray-Finned Fish do not have four limbs, so they might be considered outgroups.

From these two outgroups, sharks have a cartilaginous skeleton, while Ray-Finned Fishes have a bony skeleton. This fact makes ray-finned fishes more related to the ingroup than the sharks. So,

First outgroup → Ray-Finned FishesSecond outgroup → Sharks

Answers

Answer:

This question lacks options, options are:

a) classical conditioning

b) observational learning

c) spontaneous recovery

d) operant conditioning.  

The correct answer is a.

Explanation:

The classical conditioning theory derives from the experiments of the Russian physiologist Ivan Pavlov, he hypothesized that when any stimulus predicts the occurrence of another stimulus that triggers an automatic response, that first stimulus would acquire the ability to trigger that response, in other words , is a type of learning according to which an originally neutral stimulus, which does not provoke a response, becomes able to provoke it thanks to the associative connection of this stimulus with the stimulus that normally provokes said response. The conditioning of the immune response is built on the same principles of the classical conditioning paradigm described by Ivan P. Pavlov in which an environmental stimulus that by itself does not produce any immune reaction (conditioned stimulus), is associated with substances that stimulate or they suppress immune function (unconditioned stimulus), and finally, by presenting the conditioned stimulus alone, trigger the appropriate immune response.

A friend who is not taking your Biology course fills a cup with ice and then a drink. The friend asks you why the ice in the cup is floating, and you are able to say that Group of answer choices water vapor is less dense than liquid water. ice is denser than liquid water. convection currents caused by temperature differences push upwards on the ice. the molecules are closer together in ice than in liquid water. the molecules are farther apart in ice than in liquid water.

Answers

Answer:

the molecules are farther apart in ice than in liquid water.

Explanation:

The correct answer would be that the molecules of water are farther apart in ice than in liquid water.

Water molecules in ice form are usually less dense than water molecules in liquid form. The water molecules in ice usually arrange themselves in a lattice form, unlike the random form in liquid water. This arrangement makes water molecules in ice to be more evenly spread out than in their liquid counterpart. Thus, ice is usually less dense than liquid water and will obey the principle of flotation by floating on water.

The ice in the cup is floating is due to: the molecules of water are farther apart in ice than in liquid water.

The density of a substance is the mass of the substance per unit of its volume. The formula to calculate the density is :

[tex]D = \frac{m}{v}[/tex], where D = density, m = mass of the substance, and v = volume

The density is the factor that determines if a substance will float or sink. The less-dense substance floats whereas, the more-dense object sinks.When water freezes to form ice then water molecules show expansion to create an open cage-like structure.This cage-like structure decreases the density of ice than the water so mass ice will have more volume as compared to liquid water.

Thus, the ice floats on water - the molecules of water are farther apart in ice than in liquid water.

Answers

Answer:

125

Explanation:

The correct option would be 125.

The carrying capacity of a particular environment generally refers to the maximum number of individuals of a particular species that the environment can support at a particular time based on the resources it has. Hence, the maximum population of a species will normally oscillate around the carrying capacity of the environment where it is found.

In the case of the elephants in the illustration, the maximum population recorded was 125. The population decreased from this value at some point only to increased back to it later.

Hence, the carrying capacity for the elephant is 125.

Cyanide inhibits cytochrome c oxidase, a component of the electron transport chain. If cyanide poisoning occurs, would you expect the pH of the intermembrane space to increase or decrease

Answers

Answer:

Increases.

Explanation:

The pH of the intermembrane space increases as the poisoning of cyanide occurs. After cyanide poisoning, the electron transport chain can stop pumping of electrons into the intermembrane space. The pH of the intermembrane space would increase, the pH gradient would also decreases, and ATP synthesis would stop to occur. The pH of the intermembrane space is neutral i.e. 7 but due to cyanide it move towards basic.

Answer:

Cyanide inhibits cytochrome c oxidase, a component of the electron transport chain. If cyanide poisoning occurs, the pH of the intermembrane space becomes more basic. The electron transport chain can no longer pump hydrogen ions into the intermembrane space and ATP synthesis stops.
