11- El Pirata Barba Plata ha llegado a la isla del Coral para buscar un
tesoro. En el mapa pone que, desde la orilla, debe recorrer 3,7 hm a la
pata coja hacia el centro de la isla, y después otros 8,5 dam dando
volteretas en la misma dirección. ¿Cuántos metros recorrerá en total
desde la orilla hasta el tesoro? * cuál es la repuesta ​

Answers

Answer:

El pirata recorrerá 455 metros

Explanation:

3,7 hectómetros (hm) = 370 metros (m)

8,5 decámetros (dam) = 85 metros (m)

>> Distancia en metros = 370 m + 85 m  = 455 metros

El hectómetro (hm) es una unidad de longitud que equivale a 100 metros, donde el prefijo hecto indica la equivalencia a 100 metros. Por su parte, el decámetro (dam) equivale a 10 metros, donde el prefijo deca indica la equivalencia a 10 metros.

Use your knowledge of relationships in a food chain, describe how a cow gets the energy it needs to survive YOU MUST USE THE WORDS sunlight, photosynthesis, producer and consumer in your answer

Answers

Answer:

All energy on Earth originally comes from the Sun. Plants use sunlight in a process called photosynthesis, to make their own food and provide energy.  This is why plants are producers, because they make their own food. Cows eat plants, namely grass. So, when the cow eats the grass, the energy from the grass transfers to the cow. This is why cows are consumers, because instead of making their own food, cows, like humans, must consume their food to survive.

Which atom has two unpaired electrons in the outer valence
shell?
O helium
hydrogen
Oxygen
Olithium

Answers

Answer:

Oxygen

Explanation:

The electrons present in an atom are arranged in shells or orbitals. The electrons are filled into these shells based on their energy levels with those shells closest to the nucleus filled first as they have the lowest energies.

The arrangement of electrons around the nucleus of an atom is known as electronic configuration. The outermost electron shell of an atom is known as a valence shell shell and the electrons found in this shell are known as valence electrons. The electrons usually exist in pairs. The first shell can only contain two electrons; the second shell can contain 8. the electrons are singly filled first before pairing occurs.

The electronic configuration of the atoms of the elements in the option are as follows:

Helium : 1s² ; valence electrons are 2 which are both paired

Hydrogen: 1s¹ ; valence electron is 1

Oxygen : 1s²2s²2p⁴ ; valence electrons are 6 wit two unpaired electrons

Lithium : 1s²2s¹ ; valence electron is 1

Helium has two valence electrons but they are paired as its 1s shell can only contain a maximum of two electrons.

Oxygen has 6 valence electrons. Two of these electrons are paired while the other two are unpaired.

Which statement about ecological organization is correct?

O Biosphere is a part of the ecosystem
Submit
Request Answer

Answers

Answer:

Biosphere is a part of the ecosystem

The correct statement about ecological organization is:

An organism is part of a community.

The levels of ecological organization are a hierarchy of categories that go from the micro to the macro (and vice versa), showing us different dimensions of analysis of living beings.

These levels are: organism, population, community, ecosystem, biosphere and biome.

The community is the level made up of a set of organisms of different species, which interact with each other in a specific area.

This includes life forms of all phyla: animals, plants, fungi, bacteria, etc. .

But in turn organisms interact, and these interactions can prevent some very similar species from coexisting (competitive exclusion principle), or the presence of a predator can cause two competitors to remain in low density and therefore there are no exclusion.

Therefore, we can conclude that the organisms of any species (plant or animal) are part of a community and that they coexist in a defined space (the biotope) that offers the external conditions necessary for their survival.

How is tonicity affected by solutes?

Answers

Unlike osmotic pressure, tonicity is influenced only by solutes that cannot cross the membrane, as only these exert an effective osmotic pressure. Solutes able to freely cross the membrane do not affect tonicity because they will always equilibrate with equal concentrations on both sides of the membrane without net solvent movement.

The third time he plays Taylor Swift. When he plays Taylor Swift, Maggie immediately and starts to smile. •What is the independent variable? •What is the hypothesis? •What is the dependent variable? •Milhouse says Bart needs to try to see what Maggie will do if he doenst play any music At all. What is this called?

Answers

Answer:

Independent variable: THE TYPE OF MUSIC PLAYED

Dependent variable: MAGGIE'S TEARS

Hypothesis: IF Taylor Swift's music is played, THEN Maggie will stop crying

Control group

Explanation:

The hypothesis of an experiment is a testable explanation given to possibly solve an observed problem. In this question, Maggie thinks Taylor Swift's music will get Maggie to stop crying, hence, one can hypothesize that: IF Taylor Swift's music is played, THEN Maggie will stop crying

Independent variable is the variable that the experimenter manipulates or changes in order to bring about an outcome. The independent variable in this experiment is the THE TYPE OF MUSIC PLAYED by Bart because it is what is changed.

Dependent variable is the variable that is being measured. It responds to the changes made to the independent variable. In this experiment, the dependent variable is MAGGIE'S TEARS.

Milhouse says Bart needs to try to see what Maggie will do if he doenst play any music At all, this is called the CONTROL GROUP because the control group of an experiment is the group that does not receive any experimental treatment i.e. the independent variable is not added.

The brain is the most important part of the body. It controls and runs all functions of the body. It is walnut shaped and present in the head of the body. The brain is divided into two hemispheres. The left and the right hemisphere.

The brain is also divided into frontal and parietal lobes. The frontal lobe is present in the front section, and it controls social interaction, problem-solving, motor functions, etc.

So if the frontal lobe will be affected, the social behavior also gets affected and the person becomes irritable and aggressive.

What are animal cells?

Animal cells are eukaryotes that lack cell walls but have almost the same components as plant cells. The cytoplasm is the component of the cell where all the organelle lies.

The nucleus is the central organ that is involved in genetic replication and transcription and translation. Mitochondria are involved in the metabolic process and release of energy.

Golgi are involved in the packaging and transport of the proteins and ER produces proteins that are transported to the Golgi. Vacuoles though are present in small quantities they aid in the accumulation and elimination of the waste product.

One of the main contributing factors to the outbreak of the American Revolution was the problem of taxation without representation. Unlike the people living in various parts of England, American colonists did not have their own representatives in the British Parliament. This meant that the Parliament could essentially make any decision they chose in regards to the colonies without the consent of the colonists themselves. The Parliament naturally used this to their advantage, mainly by passing acts that increased taxes on many different goods the colonists had to import from England. Eventually, the colonists grew enraged over Parliament's abusive tactics and the ridiculously high taxes they imposed and the revolution was born.
