If Earth suddenly increased in mass, what might happen to its orbit around the Sun?
It says biology but it is just science
Answer:
If the orbit of the Earth changes, then the distance between the Earth and the Sun changes. If you tug on an object once (as you would, if you suddenly increased the mass of the sun), you'll likely pull a circular orbit into a more oval, looping orbit.

State the factor that limits photosynthesis when the stomata are closed.
In photosynthesis, if the stomata are closed to save water, then carbon dioxide cannot enter the leaf, and carbon dioxide could become the limiting factor.
What do you mean by photosynthesis?Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas. After the sugar is produced, it is then broken down by the mitochondria into energy.
Example: Green plants are nature's brilliant entities that come under this category. They carry out a photosynthesis cycle by taking in carbon dioxide and fixing it into carbohydrates (energy storage molecule).

A community wants to build an energy source to replace its coal power plant. The planners want it to be safe, renewable, and have a minimal impact on the environment.
Answer:
Solar energy can be used
Explanation:
Solar energy can be regarded as a radiant light and heat, it is an energy that is gotten from the Sun which is been trapped with the help of
range of ever-evolving technologies. This technologies could be photovoltaics as well as solar heating, and solar thermal energy. Solar energy is gotten from the sun and is been converted to "thermal energy" or "electrical energy". It's one of most abundant source of renewable energy with minimal impact on the environment. It is a very safe form of energy since it doesn't release CO2 or carbon monoxide to the atmosphere like coal power plant
Explicadme por favor porque se dice que los musgos y los helechos tienen un ciclo de vida con alternanciade generaciones
Answer:
Porque en estas especies la fase dominante es el gametofito (haploide)
Explanation:
El ciclo de vida de las plantas superiores se caracteriza por la alternancia de generaciones, es decir por un ciclo de vida compuesto por una fase de reproducción sexual que da lugar a una generación diploide (2n), seguida por una fase de reproducción asexual que da lugar a una generación haploide (n). La fase diploide es conocida como generación esporofítica, una fase caracterizada por la formación de un cigoto diploide (2n) y producción de esporas por meiosis, mientras que la fase haploide es conocida como la generación gametofítica la cual da lugar a los gametos haploides. En plantas terrestres no vasculares (como por ej. musgos y helechos), la fase dominante es el gametofito haploide, el cual es fotosintético y autosuficiente. Por otra parte, en plantas con semillas (gimnospermas y angiospermas), la generación esporofítica es la dominante, siendo el gametofito muy reducido y dependiente del esporofito para nutrirse.

Why does high air pressure usually indicate dry weather conditions? A) It is easier for condensation to occur and for clouds to form. B) It is harder for evaporation to occur and for clouds to form. C) The air particles are not closely packed together. D) The air particles have more room for water particles.
Answer:
B
Explanation:
High air pressure usually indicates dry weather conditions because It is harder for evaporation to occur and for clouds to form. Therefore, option B is correct.
Why does high air pressure usually indicate dry weather conditions?High air pressure usually indicates dry weather conditions because it is associated with descending air, which suppresses cloud formation and precipitation.
When air pressure is high, it means that the weight of the atmosphere above a particular location is greater than usual. This causes the air to sink down toward the Earth's surface, which creates a stable atmosphere. As the air sinks, it becomes warmer and drier, which inhibits the formation of clouds and reduces the likelihood of precipitation.
Therefore, high air pressure is generally associated with stable, dry weather conditions. Thus, option B is correct.

50 POINTS AND BRAINLYEST! These graphs shows a change in four types of greenhouse gases from 1975 to 2015. Based on the results of your experiment, how might these changes in greenhouse gases affect Earth's temperature? Which is the only greenhouse gas to show a downward trend in its concentration?
Answer:
CFC-11- the red gas.
Explanation: I looked it up and it is true. This gas as been decreasing today! The gas has decreasing since 1990! God Bless.
CFC-11 is the only greenhouse gas which show a downward trend in its concentration. It is a widely produced man-made chemical with a variety of applications.
What are Greenhouse gases?A greenhouse gas is a gas which absorbs and emits radiant energy within the thermal infrared range of light, this causes the greenhouse effect which results into global warming. The primary greenhouse gases which are found in the Earth's atmosphere include water vapor, carbon dioxide, methane, nitrous oxide, and ozone gas.
CFC-11 (Chlorofluorocarbon) was a widely produced man-made chemical with a variety of applications which include predominantly the use as an aerosol propellant, in the production of insulating foams, as a solvent and as a refrigerant for air conditioners.

C. Humans could live off less food over time.
D. The human population would decrease over time.
Answer: c humans would find more efficient ways of growing crops
Explanation:
Malthus fail to take into consideration that humans would find more efficient ways of growing crops. The correct option is B.
What is population?A population is the total number of individuals who reside in the same location.
The population of a city is the multitude of people who live there. These people are referred to as residents or tenants. The population includes all people who live in that specific area.
The population represents the total number of people living in a specific area at a given time.
The population is an important factor in balancing the environment; the population should be in rebalancing with the means and resources.
An imbalance between births and deaths is the primary (and perhaps most obvious) cause of population growth.
Malthus fails to consider that humans would develop more efficient crop-growing methods.
Thus, the correct option is B.

Using energy as the factor, what case can be made for eating vegetarian?
Explanation:
One of the benefits of a vegetarian diet is a reduction in your impact on the environment. Animals store only a small fraction of the energy they extract from the food they eat, and the rest is wasted as heat.
A case that can be made for vegetarians is that there's more energy that's available to them.
Vegetarianism refers to the practice of abstaining from eating meat. A vegetarian diet typically contains grains, vegetables, fruits, etc.
It should be noted that as a vegetarian, there's more energy that's available to the person. This is because plant-based diets are more energy-efficient than livestock-based diets.

In heterosexuals, discuss how STIs are passed from to another, and if not passed, explain not.
Answer:
People who have an STD may be at an increased risk of getting HIV.1-3 One reason is the behaviors that put someone at risk for one infection (not using condoms, multiple partners, anonymous partners) often put them at risk for other infections. Also, because STDs and HIV tend to be linked, when someone gets an STD it suggests they got it from someone who may be at risk for other STDs and HIV. Finally, a sore or inflammation from an STD may allow infection with HIV that would have been stopped by intact skin.
Explanation:
Answer:
STIs are passed through sexual contact/intercourse and can also be passed through blood and other body fluids. for example aids can be passed through a aids victims blood getting into you're system
