Explanation:
A planet is at equal distance from two stars, Star 1 and Star 2. If both stars have the same mass,
they will not pull each other with a gravitational force
they will pull the planet with equal gravitational force
Star 1 will pull the planet with a greater gravitational force than Star 2
Star 2 will pull the planet with a greater gravitational force than Star 1
Answer:
In this situation both o the stars will pull the planet with equal gravitational force.
Explanation:
The reason behind this is that gravity works according to the mass an object has. Therefore if we have two corpses with the same amount of mass they are going to pull the objects with the same strength. Now, in our case, they have a planet between both of them. Thus, they are going to pull it to them with the same gravitational force because they have the same mass, and are at the same distance. If one of them had a bigger mass that would pull the planet with more gravitational force, as well as if that star was closer to the planet.
Answer:
B in corrrect
Explanation:
You are evaluating the effect of different types of fertilizers on plant growth. You plant 12 tomato plants and divide them into three groups, where each group contains four plants. To the first group, you do not add fertilizer and the plants are watered with plain water. The second and third groups are watered with two different brands of fertilizer. After three weeks, you measure the growth of each plant in centimeters and calculate the average growth for each type of fertilizer. Identify the independent variable, dependent variable, control group, and experimental group from this experiment?
Answer:
Control group - the plant group which has not received the fertilizers treatment.
Experimental group- the groups treated with different varieties of fertilizers.
Independent variable- amount of water and fertilizers
Dependent variable- growth of plants
Explanation:
A scientific experiment is performed in a way that the experimental samples are classified into the control and experimental groups. Also, the experiment involves various variables to be studied which can be classified as an independent variable and dependent variable.
In the given question, the experimental samples are:
1. Control group- The samples which are not provided with the variable being studied like the experiment is performed to test the effect of fertilizers and "the plant group which has not received the fertilizers treatment" can be considered the control group.
2. Experimental group- the samples in which the variable to be studied are provided with that is "the groups treated with different varieties of fertilizers."
In the given question, the variables are:
1. Independent variable- the variable which can be changed or modified or can change on their own like "amount of water and fertilizers" in the experiment.
2. Dependent variable- the variable which is being tested, can be measured and is dependent on an independent variable like the " growth of plants" in the experiment.

Arctic ice retreat is threatening many species in this ecosystem. Their resources are being cut and they are needing to find new ways to survive. Do you think in your lifetime you will see drastic effects to the species in this ecosystem and why? Will that affect other ecosystems?
Answer:
no
Explanation:because they will find new ways to survive in the environment
Answer:
We are already seeing drastic effects to the ecosystem and it's wide assortment of species. Animals such as polar bears, and seals are losing their breeding and hunting grounds. Polar bears in particular are losing their ways to catch seals for food and interbreeding with grizzly bears. Fish and whales from warmer parts of the world are starting to move up north and are becoming invasive. Most importantly, since cold water from the melting ice are mixing with ocean currents, global climates and weather systems are changing course. Ultimately, in about 500 years, there could be a large Global Climatic Shift that may put us into another Ice Age.

does species extinction help with habitat destruction
Answer:
Yes, it does.

What part of the respiratory tract is considered the respiratory zone?
A. Bronchioles
B. Larynx
C. Trachea
D. Alveoli
Answer:
D. Alveoli
Explanation:
Functionally, the respiratory system is separated into a conducting zone and respiratory zone:
Conducting zone consists of the nose, pharynx, larynx, trachea, bronchi, and bronchioles. These structures form a continuous passageway for air to move in and out of the lungs.
Respiratory zone is found deep inside the lungs and is made up of the respiratory bronchioles, alveolar ducts, and alveoli. These thin-walled structures allow inhaled oxygen (O2) to diffuse into the lung capillaries in exchange for carbon dioxide (CO2).
The respiratory zone begins where the terminal bronchioles join a respiratory bronchiole, the smallest type of bronchiole, which then leads to an alveolar duct, opening into a cluster of alveoli.
Answer:
Yep, the correct answer is D.) Alveoli
Explanation:
Hope this helped you!Have a great day(:

Explain why the forest ecosystem is a system.
Answer:
Like all ecosystems, forests consist of many interacting parts. They include living organisms such as plants, animals, and fungi. Forests also include non-living components that these organisms depend on, such as the soil and climate. As stated in the article, one change, such as pollution, can cause a ripple effect through the ecosystem. Dying lichens are one of the earliest signs of pollution. In turn, the loss of the lichens can cause a decline in species that rely on the lichens for survival.
