Answer:
Hi there, so the population pyramid visualizes two variables which are sex and age but it doesn't tell us the actual number of population within a region it only collects the sex (female and males) and the ages (ranging from infant to elderly).
So the only thing that population pyramid data can't collect is the actual population in number.
Hope this helped :)
The population pyramid, therefore, depicts the two factors of sex and age, but it is silent on the region's actual population size instead, it simply gathers data on ages and sex (females and men) (ranging from infant to elderly).
What is the population?As a result, the only thing the population pyramid data cannot measure is the size of the population.
Population pyramids do have certain restrictions, though. It is typically impossible to tell the relative contributions of various demographic processes on population age structure since they simply provide the size of each age-sex group in the population.
Therefore, depicts the two factors of sex and age, but it is silent on the region's actual population size instead, it simply gathers data on ages and sex.

explain why plants do not burst when immersed in distilled water
Answer:
it becames turgid
Explanation:
Plant cells have plasma membrane and rigid cellulose cell wall. When the cell is placed or immersed in distilled water, the water is absorbed by osmosis. As the cell becomes turgid, the cell wall creates an inward force i.e wall pressure that prevents the cell from bursting.
Answer
According to EasyEliMu,
Plant cells have cells membrane and cell wall. When the cell is placed or immersed in distilled water, the water is absorbed by osmosis. ( This is the reason why plants do not burst!!! ) As cell becomes turgid, the cell created an inward force, wall pressure that prevents the cell from bursting. Isotonic solution- a solution which has the same concentration as the cell sap.

An intestinal epithelial cell powers the movement of glucose into the cell against its concentration gradient by simultaneously transporting sodium down its concentration gradient. Which transport mechanism is responsible?
primary active transport
Secondary active transport
osmosis
facilitated diffusion
Answer:
Secondary active transport by a symporter
Secondary active transport includes uphill transport of one substance against its concentration gradient coupled with downhill transport of another substrate. Glucose is transported against the concentration gradient into the cytoplasm and this active transport is driven by downhill transport of Na+ into the cells. This makes the transport of glucose a secondary active transport. Both glucose and Na+ are transported into the cell (in the same direction). Since both are moved simultaneously in the same direction, it is a symport.
Explanation:
Answer:
Primary osmosis diffusion
Explanation:
That is because intestinal cells give glucose to concentrional cells by transporting coca colas from walmart to ikea.
compare the reproductive strategies of a short lived species such as a starfish and a long lived species such as a hippopotamus
Answer:
Starfish reproduce every winter by ejecting there eggs into the water, since they only live on average 35 years they reproduce about 35 times in their lifetime. Only a couple of the eggs will fertilize and turn into a Starfish.
Hippos are the only mammals in Africa that reproduce in water, Hippos reproduce in May and through June. Hippos usually live to around 40 to 50 years, and most hippos through May and June reproduce more than one time.
Explanation:
Hippos strategies of reproducing are better than Starfish.
Hola, esto no es sobre la escuela, pero estoy desesperada: Mi gata ayer tuvo 5 crías que ya tomaron calostro, pero la gata se ve mal y muy cansada ,cabe aclarar que sus hijos están todo el día tomando leche pero la gata se ve mal y siento que no le va a alcanzar la leche, la quiero ayudar porque se ve muy mal, cansada y decaída. Me pueden decir algún sustento (casero o no) para poderles darles sin eliminar por completo la leche materna? Quiero que que la gata y sus hijos estén bien. Si me ayudan se los agradecería .
Answer:
Hola, para resolver tu problema debes tener en cuenta tanto a tu gata como a sus crías.
Primero, respecto a la madre, una buena alternativa serian inyecciones de vitaminas y suero, que la ayudarían a reponer energías y a generar más alimento para sus crías. Pero también la ayudaría a sentirse menos decaída, lo cual mejoraría su estado de ánimo.
Por el lado de las crías, si lo que deseas es que se alimenten por otra vía que no sea la de su madre, una alternativa ideal es la leche maternizada artificialmente, que es un alimento específico para gatos recién nacidos, aunque es bastante costoso de adquirir. Otra alternativa, ya casera, es hervir arroz, colar los granos y utilizar el agua en donde se cocinó como alimento para los cachorros. Obviamente, debes dejar enfriar el líquido, pero una vez a temperatura natural tendrá muchos nutrientes que habrá absorbido de los granos de arroz y servirá como sustituto de la leche materna.

which of the following is NOT an example of an internal structure adaptation?
fish gills
xylem in plants
hollow bird bones
tree roots
Answer:
hollow bird bones or option c
Explanation:
because it helps them fly better
Hollow bird bones is not an example of an internal structure adaptation.
What is Internal structure adaptation?Any heritable characteristic that enables a plant or animal to survive and procreate in its environment is referred to as an adaptation. Individuals of a species can differ in a wide range of ways; some may be larger, hairier, better able to fend off illnesses, or even have smaller ears.
Their genes, which are inherited from their parents and later passed on to their own offspring, are mostly responsible for determining these traits.
The proportion of people who possess that favorable feature or adaptation will rise over generations until it becomes a characteristic shared by the entire species.
Therefore, Hollow bird bones is not an example of an internal structure adaptation.

What is the direct cause of most earthquakes?
O Gravitational pull on bedrock by the moon
O deposition of sediment in lakes and oceans
O movement of bedrock along a fault line
O heat exchange betwęen the crust and the atmosphere
Answer:
Pretty sure it's C or B? Most likely C.
The direct cause of most earthquakes is the movement of bedrock along a fault line. Earthquakes occur when energy stored in the Earth's crust is released suddenly, causing the ground to shake. Hence option D is correct.
What is an earthquake?An earthquake is a sudden and rapid shaking of the Earth's crust caused by the breaking and shifting of rock beneath the Earth's surface. The Earth's crust is made up of tectonic plates that constantly move and interact with each other.
When these plates move against each other, they create pressure that builds up over time until the rock breaks, causing an earthquake.
This energy is released when two blocks of rock, called tectonic plates, move relative to each other along a fault.
The blocks may become stuck, and as the pressure builds up, they may suddenly slip, releasing energy in the form of seismic waves that cause the ground to shake.
The intensity and magnitude of an earthquake depend on the amount of energy released and the distance from the epicenter.
While other factors such as volcanic activity, landslides, or human activities can also cause earthquakes, movement along a fault line remains the primary cause.
Hence option D is correct.
