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.

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
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.

What is the brain?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.
Thus, the correct option is D, antisocial and aggressive behavior.

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?
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.

stable
Explanation:
Another word that can be used to describe homeostasis is - stable
HomeostasisIt is an organism's process of maintaining a stable internal environment suitable for sustaining life. It describes the internal stability of an organism.
Most of the homeostasis process is maintained by the cell membrane by allowing what or what not to enter or exit in the cell, however, the complete cell takes part in the homeostasis.

How is tonicity affected by solutes?
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.

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

Eukaryotic cells are enclosed in the membrane, and the nucleus is bound by a nuclear membrane. Major parts of the eukaryotic animal cell are the nucleus, cytoplasm, mitochondria, Golgi, ER, etc.
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.
