Answer:
Nitrogen-fixing bacteria, microorganisms capable of transforming atmospheric nitrogen into fixed nitrogen.More than 90 percent of all nitrogen fixation is effected by these organisms, which thus play an important role in the nitrogen cycle.What are the two characteristics of a species?
Answer:
They can reproduce and have genes
Explanation:
Answer:
A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche.

Consider the following experiment. A plant is set in one corner of a box. A top is put on the box so that the hole in the top is opposite to the plant.
Over the next week, the plant in the box should:
grow downward
grow away from the hole
bend and grow towards the hole
die for lack of air
Answer:
It will bend and grow towards the hole because the sunlight will shine through the hole and the plant will sense it so it will grow towards the light. I hope I could help you :)

Why is it important for a pregnant woman to know her Rhesus blood type, and the Rh blood type of the father of her baby?
Answer: One of the first tests a pregnant woman should expect is a blood-type test. This test checks her blood type and Rh factor. Her Rh factor may play a role in her baby's health, so it's important to know this information early in pregnancy.
Explanation: if you're Rh negative and your baby is Rh positive, your body might produce proteins called Rh antibodies after exposure to the baby's red blood cells. The antibodies produced aren't a problem during the first pregnancy. The concern is with your next pregnancy.

Explain how abiotic factors can have influence on the survival for individuals through natural selection.
Selection: Organisms live within ecosystems, which are made up of various biotic and abiotic factors. These factors contribute to selecting which variations provide the individual with an increased chance of surviving. ... Examples of abiotic factors include temperature, shelter, sunlight, water and nutrients.
Answer:
Biotic and abiotic factors are the environmental conditions that the organisms have to face to live in a specified environment.
Abiotic factors
Abiotic factors are the physical and chemical conditions of an environment. For example : heat, salinity, pressure, light, wind, pH ...
Biotic factors
Biotic factors are all the biological conditions of an environment for a specie/taxa. It can include prey and predator abundance, available food amount, available space, intra and interspecific competition...
The development of organims is under the control of abiotic factors. Some are adapted to heat, cold etc ... The abiotic factors will define which organisms are able or not to live in a specified place.
The living organisms will constitute the biotic factors, which define if and how can an organism live in a specified environment.
So, the abiotic factors are controling the biotic factors of an environment.

Answer:
1. Ribose (type of sugar found in ATP and ADP molecules)
2. The 3 phosphate groups (Energy is stored in the 3 phosphate groups and in order to bring the stored energy to use, the last phosphate bond breaks and energy is released)
3. ATP has a higher energy potential than ADP (This is cuz, ATP has 3 phosphate groups and ADP has 2 phosphate groups)

Answer:Pollution enters the Earth's atmosphere in many different ways. Most air pollution is created by people, taking the form of emissions from factories, cars, planes, or aerosol cans. ... Some types of air pollution, such as smoke from wildfires or ash from volcanoes, occur naturally. These are called natural sources.
Explanation: Make sure you subscribe to my channell if you like imvu its meiyanna calloway
Answer:
Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
Explanation:
Acid rain that seeps into the ground can dissolve nutrients, such as magnesium and calcium, that trees need to be healthy. Acid rain also causes aluminum to be released into the soil, which makes it difficult for trees to take up water.
What happens to a plant cell during cellular respiration?
The cell rests
The cell absorbs water
O The cell releases oxygen
The cell releases stored energy
Answer:
releases energy
Explanation:
Answer:
The cell releases oxygen The cell releases stored energy
Explanation:
During cellular respiration, the mitochondria take in carbon dioxide and purify it back into oxygen. Huamns also have this process, but in a much smaller manner. This process is what gives us oxygen on our planet.

Which genetically modified organism will best prevent farmers from losing their crops during transport to grocery stores?
oranges that have a prolonged shelf life
corn with a high yield
butter squash that have high nutritional value
fruit with a vaccine
(ANSWER IS A, I saw nobody with the question and i got the answer correct)
EDGE 2021
Answer:
oranges that have a prolonged shelf life
Explanation:
The genetically modified organism have higher shelf life which helps the farmers to transport the products from one place to another without causing damage to it. The local varieties of fruits have low shelf life due to which farmers receives great losses while transporting it to far places or markets as compared to genetically modified varieties of fruits that have higher shelf life which prevent loses to the farmers during transportation.
Answer:
As said above its A

Absorption spectroscopy is a technique used to determine the composition of a substance. Each substance tends to behave consistently in terms of which types of radiation it absorbs. When a material absorbs a unique set of different colors of visible light, the characteristic set of color bands observed through a spectroscope is the material's spectrum. The spectra of two stars are shown below.
Modified image courtesy of NASA
Star 1 is a nearby star and star 2 is a similar type star much further away from Earth. When comparing the spectra, the lines in the spectra for star 2 are closer to the red end of the light spectrum. This is called red shift.
From this type of information, scientist believe that most stars in the universe are moving away from each other and from the Earth. How can redshift be used as evidence to support the Big Bang theory?
A.
It provides evidence that some stars remain motionless while others move rapidly, showing that the universe is expanding in very few areas.
B.
It provides evidence that some stars are pulled toward a point source, and some move away from a point source, showing the universe may be contracting.
C.
It provides evidence that stars are moving away from a single point of origin, showing that the universe is expanding.
D.
It provides evidence that stars are moving closer to a single point of origin, showing that the universe is contracting.
Answer:
It provides evidence that stars are moving away from a single point of origin, showing that the universe is expanding.

Explanation:
The human genome project was able to map the human genome and it is now
completed. Why is this important in science?
Answer:
What is the Human Genome Project? The Human Genome Project was the international research effort to determine the DNA sequence of the entire human genome. In 2003, an accurate and complete human genome sequence was finished two years ahead of schedule and at a cost less than the original estimated budget.
Explanation:
The finished sequence produced by the Human Genome Project covers about 99 percent of the human genome's gene-containing regions, and it has been sequenced to an accuracy of 99.99 percent.
