Name the four ways exoplanets are discovered? Which of those methods are dependent upon another star?
Answer:Any planet is an extremely faint light source compared to its parent star. For example, a star like the Sun is about a billion times as bright as the reflected light from any of the planets orbiting it. In addition to the intrinsic difficulty of detecting such a faint light source, the light from the parent star causes a glare that washes it out. For those reasons, very few of the exoplanets reported as of April 2014 have been observed directly, with even fewer being resolved from their host star

Go outdoors and look for ten different plants. See if you can figure out which type of seed dispersal each plant uses, and make notes about each one. Some may have more than one method of dispersal. If you find a plant that you suspect disperses seeds in a way that you haven't studied, try to figure out how the plant does it. When you're finished, write your discoveries in a list with the name of the plant you observed (if you know it; otherwise, describe the plant).
Some you wouldn't see by stepping outside, but it gives you a general understanding of what you should be looking for.

Isobars are smooth lines that connect points of equal pressure on a map. They can be used to identify high- and low-pressure areas. In a high-pressure region, the air contracts and becomes warmer as it sinks. These regions are usually associated with dry weather caused by the evaporation of moisture. Low-pressure regions usually bring precipitation, because the air cools as it rises and the water vapor condenses. In the Northern Hemisphere, the wind blows clockwise around high-pressure areas and counterclockwise around low-pressure areas.
Question
This map shows the surface air pressure across the United States. The units are rounded to the nearest millibar. Follow the steps to complete the drawing.
Step 1: Isobars. Locate all points of 1024 millibar (mb) pressure in the northwest United States. Similar to a dot-to-dot coloring book, use a black pen to connect all four of the 1024 mb points. Your line should start and end at the point of 1024 mb pressure in Utah. Repeat this procedure with the next isobar value until all the points on the map have isobars running through them. Be sure that no set of isobars crosses another. Remember that not all isobars will be closed circles. Label each of your lines with the last two digits of the pressure reading (24, for example).
Step 2: Air Pressure. Locate the areas of the highest and lowest pressure on your map. Label these centers with a large blue letter H and a red letter L, respectively.
Step 3: Weather Conditions. Based on air pressure, locate the regions where you would expect to see rain or snow and shade them in green. Then shade the regions where you would expect to see clear skies in yellow.
Step 4: Wind Direction. Indicate the wind direction by drawing pink arrows around the letter H and around the letter L on your map.
Isolines are used to read create climatic maps. They provide information about barometric pressure, weather conditions, winds direction and speed.
How to interprete a climatic map?Meteorology is determined mainly by barometric pressure, which is the pressure exerted by atmospheric air on the earth's surface. It is measured in millibars.
Barometric pressure systems are closely associated with weather patterns, which is why it is used to create climatic maps.
Pressure,
An average pressure system ⇒ 1013 mb. A high-pressure system ⇒ 1030 mb.A low-pressure system ⇒ 1000 mb.Isobars,

The right side of the heart receives: ____________
a) oxygenated blood from the pulmonary circuit.
b) deoxygenated blood from the pulmonary circuit.
c) deoxygenated blood from the systemic circuit.
d) oxygenated blood from the systemic circuit.
Answer:
b
Explanation:
The pulmonary circulation is a division of the circulatory system in all vertebrates. The circuit begins with deoxygenated blood returned from the body to the right atrium of the heart where it is pumped out from the right ventricle to the lungs.
The right side of the heart receives deoxygenated blood from the pulmonary circuit.
What is the function of the right side of heart?The pulmonary circulation carries the oxygen-poor blood from the right ventricle to the lungs, where it obtains a new blood supply. Returning the oxygenated blood to the left atrium follows. The right side of your heart draws blood from your veins that is deficient in oxygen and pushes it to your lungs where it is oxygenated and removed of carbon dioxide. Blood that has been oxygenated by your lungs is drawn from the left side of your heart and circulated through your arteries to the rest of your body.learn more about heart here: https://brainly.com/question/988627

A doctoral student is studying the genetic makeup of a species of jellyfish that occurs at low, middle, and high latitude regions of the Pacific Ocean. On an
oceanographic expedition, she collects specimens of the jellyfish throughout its range Upon returning to the laboratory at the university, an assistant places all of the
Jellyfish in an aquarium with an average temperature of approximately 20'C. After a few days, he notes that almost two-thirds of the jellyfish have died. Using the figure
below, how would you explain which jellyfish likely make up the bulk of the survivors and what the mistake was?
A. The survivors were likely collected from the dark gray areas on the map. those from other regions could not adapt
B. The survivors were likely collected from the light gray areas on the map those from other regions could not adapt.
C. The survivors were likely from the black areas of the map but had the most advantageous genes of those collected.
D. The survivors were likely from the black areas of the map but adapted to the difference in temperature in the laboratory.
The survivors were likely collected from the light gray areas on the map those from other regions could not adapt. That is option B
The effect of temperature change on organismsThere are some organisms such as plants and animals that are capable of changing and adjusting to different environmental conditions.
Aquatic animals such as jellyfish can adapt to warmer ocean waters, but not necessarily to extreme heat or extreme cold weather. That is, it can survive the temperature of 12 - 24°C as indicated in the figure.
But some species of jellyfish that has adapted in extreme cold and extreme hot weather, may find it difficult to abruptly adapt to an average weather.
Therefore when placed in the 20°C aquarium, they couldn't survive because of the temperature of the new environment.

The Colorado River carved out a deep canyon in the habitat of an Abert’s squirrel population. This is an example of which stage of speciation? Question 3 options: The populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring. The populations successfully interbreed. The populations become totally separated from one another. The populations are isolated and thus do not interbreed.
The correct answer is the populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring.
A species is a populace whose participants can interbreed and bring fertile offspring. Reproductive isolation takes place while a populace splits into corporations and the 2 populations now do not interbreed. When populations grow to be reproductively isolated, they could evolve into separate species.
What is speciation?Speciation is the evolutionary manner via way of means of which populations evolve to grow to be awesome species. The biologist Orator F. Cook coined the time period in 1906 for cladogenesis, the splitting of lineages, rather than anagenesis, phyletic evolution inside lineages.
Hence concluded that the populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring.
