To be characterized as a chordate, an organism must:________.
A) possess a backbone in both the larval and adult stages
B) display all four key characteristics of Chordata in both the larval and adult stages
C) display each of the four key characteristics of the chordates at some point in the life cycle
D) possess a backbone in at least one life stage.
Answer:
C) display each of the four key characteristics of the chordates at some point in the life cycle
Explanation:
To be characterized as a chordate, an organism must display each of the four key characteristics of the chordates at some point in the life cycle. Therefore, the correct option is C.
To be characterized as a chordate, an organism must display four key characteristics at some point in its life cycle.
These characteristics include having a notochord (a flexible rod-like structure), a dorsal hollow nerve cord, pharyngeal slits or pouches, and a tail.
It is not necessary for all four characteristics to be present simultaneously or in both the larval and adult stages. As long as the organism exhibits these characteristics at some stage of its life, it can be classified as a chordate.

What cause the slight positive (8+) and negative (8-) poles on a molecule of H20?
Answer:
In the covalent bond between oxygen and hydrogen, the oxygen atom attracts electrons a bit more strongly than the hydrogen atoms. The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms
Because of the water molecule's bent shape and its atoms' unequal sharing of electrons, it has partial positive (δ+) and partial negative (δ-) poles. ... A hydrogen bond occurs when molecules that have hydrogen covalently bonded to oxygen, nitrogen or fluorine interact.
Explanation:
Water is said to be a molecule made of oxygen and hydrogen atoms. There is a partial negative and positive charge at the poles of water due to hydrogen bonds, and electronegativity.
What are hydrogen bonds?Hydrogen bonds are defined as weak chemical bonds and interactions that result from the electrostatic attraction between the electronegative atom and the proton. These bonds are formed by dipole-dipole interactions.
Oxygen atoms in the water molecule are highly electronegative whereas the hydrogen atom of the water molecules is proton donors. This results in the formation of hydrogen bonds between the oxygen atom of one molecule and the hydrogen atom of the other molecules.
The electron sharing between the hydrogen and the oxygen atom tends to be unequal resulting in bonds being slightly towards the oxygen atom due to its electronegative nature. This results in the formation of partial positive and negative charges.
Therefore, hydrogen bonding results in slight positive and negative charges.

Which statement about ecological organization is correct?
O An organism is part of a community.
O A community is part of a population.
O An ecosystem is made up of organisms only
O Biosphere is a part of the ecosystem
Submit
Request Answer
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.

Bart has to babysit Maggie for several nights in a row during summer vacation and makes a bet with that Taylor Swift music will get Maggie to Bart gets out the CD collection and when Maggie cries the first night, he plays The second time he plays /DC and rocks out, but she doesn't stop crying. 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.

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.

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.

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.

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
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.
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.
