Answer:
Meat-eating, or carnivorous, plants can trap and digest insects and other small animals. They do this to obtain the vital nitrogen that they need to grow. Most plants absorb enough nitrogen from nitrates in the soil. Carnivorous plants live in bogs, where nitrates are in short supply, so they need to obtain their nitrogen by digesting prey instead. Carnivorous plants have developed unique ways to catch insects, such as fluid-filled PITCHERS and spring-loaded traps.

La presencia de un núcleo organizado en el interior de la célula es característica de: a)celula procarionte b) celula eucarionte c) las bacterias d) los virus
Answer:
Translation- The presence of an organized nucleus inside the cell is characteristic of: a) prokaryotic cell b) eukaryotic cell c) bacteria d) viruses
Explanation:
Eukaryotic.These organim including man, are characterised with a double membrane nucleus, with all its inclusions. Other organisms lack a well organized membrane bounded nucleus. Rather they have orgellells that perform nearly similar functions close to the nucleus lying freely in the cytoplasm.
Nucleus is the control and coordinating centre of the cell.Genetic materials needed for instructions on how to produce other cells organelles are present in the nucleus.
Bacteria, Prokarotes contain Nucleoid, which is just an irregularly shape region, lacking nuclear membrane.
Viruses lack Nucleus.

3. group of related organisms that share features and characteristics species
4. small or underdeveloped vestigial
Answer:
1) morphology
2) speciation
3) species
4) vestigal
Explanation:
Morphology is the study of forms or the physical appearance of organisms.
Speciation is the splitting of lineage into distinct species capable of interbreeding and producing fertile offspring.
Species is a group of organisms that are genetically related and share features and characteristics. They are capable of interbreeding and produce live offsprings.
Vestigal organs are organs that have lost their function over time, they are usually small and underdeveloped. Example is the human tail bone.

What is the best method to increase the accuracy of the parallax measurement of star distances?
keep a record of the observations and do not repeat them
take observations simultaneously with different instruments
keep a gap of about six months between two observations
take observations from two points which are very close to each other
Answer:
C.
Explanation:
Parallax method is used to measure the distance of nearby objects in space or measurement of star distances. Parallax method uses the measurement of movement of star's against starts at far points as Earth revolves around the sun.
To improve the accurate measurement of star distances through parallax method, a gap of about six months between two observations.
In the parallax measurement, two angles are measured and it includes Earth on one side of its orbit, Earth six months later on the other side of its orbit and side of a triangle formed by the star. This six month gap ensures that measurement of stars is taken from two farthest points which gives a large arc length.
As parallax is based on geometry so, it ensure that the large arc length will reduce the error in the measurement of the angle and the distance will be accurate.
Hence, the correct answer is C.
Answer:
c
Explanation:
A. A scientific theory is an explanation of some aspect of the natural world. B. Theories have been thoroughly tested and are supported by multiple lines of evidence. C. A scientific theory may be modified as new lines of evidence become apparent. D. Scientific theories are concise, systematic, predictive, and broadly applicable. E. Scientific theories often integrate and generalize many hypotheses. Neil deGrasse Tyson once commented: "Some claim evolution is just a theory, as if it was merely an opinion." He went on to explain why a scientific theory, like evolution, is NOT just an opinion. Select which points he included in his argument? A) A, B, E B) A, B, D, E C) A, B, C, E D) A, B, C, D, E
Answer:
D) A, B, C, D, E
Explanation:
These are all important factors to consider when judging scientific theories. A scientific theory is not merely an inclination or vague idea a scientist has. Instead, a scientific theory is an explanation that is given to a broad range of phenomena. Scientific theories tend to be concise, coherent, systematic and predictive. However, they also admit modification as new evidence becomes apparent.

What advantage does a crop that undergoes vegetative reproduction have over plants that start from the seed? 1Points A They store nutrients. B They can travel farther. C They experience more genetic variation. D They only occur in high-resource environments.
In vegetative reproduction, new plants are easily produced and grow faster in many environments, the correct option is B: they can travel farther.
Definition of vegetative reproductionVegetative reproduction is a form of reproduction in plants in which a vegetative part of the plant such as stem, leaves and roots are used to produce new plants rather than seeds or spores.
Advantages of vegetative reproductionThe advantages of vegetative reproduction include:
the new plants contain the genetic material of only one parent, therefore, they resemble the original parent.it is an easier, cheaper and faster method of reproductiontwo parents are not requiredit does not require a high-resource environmentTherefore, since new plants are easily produced and grow faster in many environments, the correct option is B: they can travel farther.

Arteries must be thicker than veins to be able to withstand the high pressure the heart exerts as it pumps blood into them. As blood travels
through the body, this pressure decreases. Blood pressure is the lowest in the veins as the blood heads back to the heart.
Based on blood pressure differences between arteries and veins, which of these must be true?
OA Blood flow tends to be faster in arteries than in veins.
O B. Blood pH tends to be higher in veins than in arteries.
OC. Blood flow tends to be faster in veins than in arteries.
OD. Blood viscosity tends to be higher in arteries than in veins.
Answer:
A Blood flow tends to be faster in arteries than in veins.
Explanation:
Veins and arteries are both blood vessels i.e. conducts blood in the circulatory system. As rightly said in the question, the walls of the arteries are thicker and stronger than that of veins in order to be able to withstand the high pressure of blood that flows into it from the heart. The veins, on the other hand, has a lower blood pressure since blood flows back into the heart.
Based on this fact that blood flows forcefully i.e. high pressure, out of the heart into the arteries, blood will flow faster in the arteries i.e. with high speed which is responsible for the high pressure that the blood exerts on its wall.
Answer:
Option A
Explanation:
Blood flow which is characterized by its velocity tends to be faster in arteries than in veins and inversely varies as its cross-sectional area. Blood flow is faster in the arteries as it carries blood away from the heart at high blood pressure rate and this continues if the cardiac output is continually compensated for.

What would you expect to happen to the number of high tides in any given area if the rate of Earth's rotation doubles?
Answer:
high tides would also double within the span of 24 hours.
Explanation:
If the Earth's rotation doubled then the number of high tides would also double within the span of 24 hours. This is because low and high tides depend on the Earth's pull toward's the Moon, since as the ocean bulges toward the moon, a high tide is created. Therefore if Earth's rotation doubled, this would mean that pull towards the Moon would happen twice in 24 hours, and thus causing high tide twice.
Is asking two more squirrels live in Maple trees are all trees a scientific question why or why not

Imagine an object launched from Earth as shown in the image. Identify where the object has overcome the gravitational pull of Earth.
Answer:
the object defeats the force of gravity on the arrows on the left where they do not follow the circumference of the earth.
since the force of gravity makes the objects keep rotating near or even on the Earth's surface.
If any object overcomes this force, it will not rotate on the surface of the earth and will not be attracted to the center
Explanation:
this is because the center of the earth works as if it were a magnetic pole that attracts everything close to the earth to its center, if something deviates as in the arrows on the left, it means that the force of attraction towards the center or force of gravity does not act on the objective as it must have a force applied or of its own greater than that written

The bunnies in a forest have different colored fur at different times of the year. The bunnies you see have brown fur in the fall. The bunnies you see in winter have white fur. What is this an example of?
a. Evolution
b. Artificial Selection
c. Natural Selection
d. Selective Breeding
Answer: A) Evolution or B) Natural Selection
Explanation: The fur of these bunnies change color with the seasons in order to better blend into their environment. This is an example of a species evolving to better survive!
However, this could also happen as a result of natural selection. Those who were able to better survive would pass on their genes for fur that changes with the seasons.

Apuk’we, the common cattail is a versatile native edible plant for the Ojibwe people of Minnesota. They are important to the ecosystem for many reasons. They help stabilize marshy borders of lakes and ponds, help protect shorelines from wave erosion, providing spawning areas for northern pike, provide cover and nesting sites for waterfowl and marsh birds such as the red-winged blackbird, are a food source for muskrats and beavers, and humans, too. However, where native cattails once stood, now there is a vast lawn of nonnative narrow-leaved cattails or their hybrid offspring. These new cattails are taking over wetlands once populated by the native cattails, decreasing the biodiversity in these areas.
What kind of ecological relationship exists between the native and nonnative species of cattails in the Minnesota wetlands?
A) commensalism
B) competition
C) mutualism
D) predation
Answer:
B) Competition
Explanation:
The native and non-native cattails are competing for the area.
Answer:
Predation
Explanation:
The way the question is worded, gives me the effect that the nonnative species of cattails predated the native species and ultimately, lowered their numbers.
I was torn between competition or predation, but it cannot be competition due to the effect it's having on the native species. In competition, there's obvious tension between the two, though in this scenario, the species is just lowered completely. There's a chance it could be competition though, I'm not really understanding the wording of the scenario given; that's just me though.
So, ultimately, it's predation.
Which of the following statements would best describe Pseudacris crucifer?
A. larger than 1.5 inches, larger than 6 inches, warts, X-shaped mark on back
B. larger than 1.5 inches, smaller than 6 inches, warts, no triangular mark on head, X-shaped mark on back
C. smaller than 1.5 inches, warts, triangle between the eyes, stripe on back from head to tail
D. larger than 1.5 inches, smaller than 6 inches, smooth skin, triangle between the eyes
Answer:
The answer is B
Explanation:
I had this on study island.
Answer: Option D: larger than 1.5 inches, smaller than 6 inches, warts, no triangular mark on head, X-shaped mark on back
Explanation: Pseudacris crucifer is the last species of frog in the key. Therefore, one must work backwards through the entire key to determine Pseudacris crucifer's characteristics.The only way to get to step #5, where the frog was identified as Pseudacris crucifer, was to determine in step #4 that the frog had no triangular mark on its head.To get to step #4, the frog must not have had smooth skin. In order to get to step #3, our frog must have been smaller than 6 inches.Although we could have arrived at step 3 whether the frog was larger or smaller than 1.5 inches, the only answer choice provided that correctly listed the other characteristics of Pseudacris crucifer is : larger than 1.5 inches, smaller than 6 inches, warts, no triangular mark on head, X-shaped mark on back.
