Which of the following statements is true about nitrogen fixation?
a. It is done only by plants.
b. It is done mostly by bacteria.
c. It is how animals make proteins.
d. It is a form of decomposition.
Answers
Explanation:
option B is the correct one as it is done by nitrogen fixing bacteria.
It is absorbed by bacteria from the atmosphere as a gas and released to the soil, mostly as ammonia. Thus, option B is correct.
What is role of bacteria in nitrogen fixation?The purpose of nitrogen-fixing bacteria is to provide plants with a crucial nutrient that they are unable to receive naturally from the air. Microorganisms that fix nitrogen can obtain assimilate N for plants in a way that crops cannot.
More than 90% of all nitrogen is fixed by nitrogen-fixing bacteria, which makes them crucial players in the nitrogen cycle.
The majority of nitrogen fixation is done spontaneously by bacteria in the soil. In the soil, nitrogen is fixed and changed in form.
Some bacteria form symbiotic relationships with plant roots that are advantageous to both the plant and the bacteria.
Therefore, It is done mostly by bacteria.

The models below represent nuclear reactions. The atoms on the left of the equal sign are present before the reaction, and the atoms on the right of the equal sign are produced after the reaction. Model 1: Atom 1 + Atom 2 = Atom 3 + energy Model 2: Atom 4 = Atom 5 + Atom 6 + energy Which of these statements is most likely correct about the two models? Both models show reactions which produce energy in the sun. Both models show reactions which use up energy in the sun. Model 1 shows reactions in the nuclear power plants and Model 2 shows reactions in the sun. Model 1 shows reactions in the sun and Model 2 shows reactions in a nuclear power plant.
Answers
Answer:There are two kind of nuclear ractions: fusion and fission reactions.
Both release a huge amount of energy in different ways.
Fusion reactions are nuclear reations in which two smaller (lighter) atoms combine into a larger (heavier) atom, with the respective release of energy.
That is what model 1 shows:
Model 1: Atom 1 + Atom 2 = Atom 3 + energy
That is the process that happens and is responsible for the huge amount of heat produced in and released by the Sun.
In the Sun two atoms of hydrogen fuse into a larger atom of helium.
That is represented by the nuclear reaction:

A. Amount of sunlight (hours/day)
B. Mean temperature (°C)
C. Density of rose pollen produced (g/m2)
D. Amount of pollen produced by each flower (g/flower)

Answer: Density of rose pollen produced (g/m2)
Explanation:
The data that would be most useful for the scientists to collect at regular intervals on a designated test plot of rose plants is the density of rose pollen produced (g/m2).
It should be noted that the amount if sunlight or the mean temperature isn't the appropriate data that's useful in this case. Therefore, the correct option is D.

O Cells in mitosis and meiosis go through the PMAT stages once to produce diploid cells.
Answers
Answer: Cells in mitosis go through the PMAT stages once to produce diploid cells while cells in meiosis go through PMAT stages twice to produce haploid cells. (3rd option)
Explanation:
Cells in mitosis go through the PMAT stages once to produce diploid cells while cells in meiosis go through PMAT stages twice to produce haploid cells.
Mitosis is a process by which a single cell divides to produce two daughter cells. In diploid (2n) organisms, somatic cells contain two copies of each homologous chromosome, thereby mitosis will produce two identical diploid cells. Mitosis consists of four phases: Prophase, Metaphase, Anaphase and Telophase.Meiosis is a process by which a single cell divides twice in order to produce four cells with half the original amount of chromosomes, it is for that reason that meiosis is recognized as a reductional division. Meiosis is divided into meiosis I and meiosis II. The phases of meiosis I include Interphase I, Prophase I, Metaphase I, Anaphase I, Telophase I, and cytokinesis; whereas the phases of meiosis II include Interphase II, Prophase II, Metaphase II, and Telophase II, and cytokinesis.During meiosis I, the chromosome or chromosomes duplicate their genetic information (S phase of the interphase I) and subsequently homologous chromosomes exchange genetic material during prophase I. In diploid organisms, these two daughter cells generated by meiosis I divide again in meiosis II in order to form haploid (n) gametes.Learn more in:

You are touring several ecosystems, including an icy coastline in the Arctic, and a dry desert in the southwest United States. Do you predict that you will observe equal numbers of ectotherms and endotherms in all ecosystems? Explain your prediction.
Answers
Answer:
No.
Explanation:
No, we observe different number of ectotherms and endotherms in Arctic, and a dry desert ecosystems because there is difference in the temperature of both the environment. Due to difference in temperature of the external environment, the number of ectotherms and endotherms are present in that ecosystem. More number of ectoderms are present in the desert ecosystem where the ectoderms survive better than endotherms so we can say that number or population is different.

Identify the definition of biomagnification.
1.the accumulation over time of a chemical in a living organism.
2.the process of energy increasing in amount as you move up through the trophic levels in a food chain.
3.the accumulation of a chemical from food exposure that results in a concentration that is greater in higher trophic levels.
4.the process of using a microscope to inspect a living organism.
Answers
Answer:
3
Explanation:
basically biomagnification describes how toxins get in the body of a trophic level and increase over time as larger quantity of that trophic level are needed since only 10% of energy is transferred form one trophic level to the other.

What would happen to the owl population if the population of bats decreased?
Answers
Answer:
In an ecosystem if one thing goes wrong then all organisms will fall apart , so if the whole race of owls were to die then the food chain and life cycle wouldn't be able to work properly
hope it helped!
If the population of bats decreased, it could potentially have a negative impact on the owl population as owls rely on bats as a significant food source.
Owls are known to be efficient nocturnal predators, and their diet often consists of small mammals, including bats. Bats serve as a primary food source for many owl species, especially those that are specialized in hunting at night. Therefore, a decrease in the population of bats could have consequences for the owl population.
If the bat population decreased, it would likely result in a reduced availability of bats as prey for owls. This could lead to a decline in the food supply for owls, potentially resulting in reduced reproductive success, decreased survival rates, and overall population decline.
Owls have evolved to be specialized predators, and their diet may be heavily dependent on certain prey species, such as bats. The removal or reduction of a significant food source can disrupt the balance of their ecosystem and have cascading effects on the owl population.
However, it's important to note that the impact on the owl population may also depend on various factors, including the availability of alternative prey species and the adaptability of owls to find alternative food sources. Some owl species have more flexible diets and can switch to other prey items if their primary food source becomes scarce. Additionally, the overall ecological context and interactions with other species would also play a role in determining the exact outcome for the owl population.
In summary, a decrease in the bat population could potentially have negative consequences for the owl population as it would likely result in a reduced food supply. However, the exact impact would depend on various ecological factors and the ability of owls to adapt to changes in their prey availability.

A cultural complex is defined as: a several groups sharing the same trait. b a single trait spread over a geographic region. c several groups occupying the same region. d a discrete combination of traits, for example Masaai cattle herding.
Answers
Answer:
d a discrete combination of traits, for example Masaai cattle herding.
Explanation:
A cultural complex consists of different cultural traits that together create a 'culture'. Thus, a cultural complex can be defined as a group of cultural traits that are functionally interrelated. A cultural trait can in turn be defined as any acquired knowledge that is learned by social interaction and interpersonal relationships. Moreover, a cultural pattern occurs when cultural traits and cultural complexes associate each other in functional roles.
