Manish is growing crop of Bengal gram and he did not add any nitrogen fertilizers to the soil. Would he get a better yield? How would the plants cope up with their nitrogen requirements?
Answer: Bengal gram is a leguminous plant.
Explanation:
Legumes are the plants that can fix nitrogen by symbiotic mutualistic association with the soil bacteria. The bacteria converts atmospheric nitrogen into plant usable for like ammonia and derives nutrition from the plant in return. This association results in the formation of root nodule for uptake of nitrogen derivatives from the soil and return of nutrients to bacteria. Bengal gram is a leguminous plant so it can avail nitrogen with symbiotic association with the bacteria in the soil. Although nitrogen is not given in the fertilizer but the gram crops can sustain themselves by obtaining nitrogen from the soil in association with nitrogen fixing bacteria.
The diploid cells of a polar bear contain 74 chromosomes.
How many chromosomes are there
The genetic material that is passed from a parent to a child is called a chromosome. With a diploidy of 74 chromosomes, the haploid cell of the polar bear will have 37.
What is the difference between haploid and diploid cells?The number or ploidy of chromosomes in the somatic or germinal cells determines whether a cell is diploid or haploid. A twofold set of chromosomes is referred to as diploidy and is symbolized by the number 2n.
Haploidy, which is denoted by the number n, refers to the single or partial set of chromosomes found in germinal or reproductive cells. They describe the gametes that participate in fertilization.
If a polar bear's diploid cells (2n) have 74 chromosomes, its haploid cells (n) will have the following chromosome makeup:
2n = 74
n = 37
Therefore, option C is correct.

Answer:
True
Explanation:
The weight of an object is measured by an equal arm balance. The mass of an object is measured by a scale. The mass of an object changes with elevation. The weight of an object will change with elevation on the Earth.
1Which waste needs to be sorted and which can be disposed of in the general bin? 2How do you know which wastes can be recycled and sorted? 3Provide arguments to show that we save energy by making items from recycled materials.
Answer:
Waste which needs to be sorted are: Plastic, paper, and alminium. And the ones can be disposed can be any other items such as food, sweet wrappers, plastic wrapping, and broken glass.
The waste bags are opened and the waste is put onto a conveyor belt and moved into a processing area. First, the waste will go into a pre-sort area, where any items that can't be recycled are removed, and then the materials move into an area where they can be sorted automatically by machines, or manually by workers.
As most people know, recycling can reduce pollution, animal harm, and energy because we won't need as much material to be making the same thing over and over again so in general, recycling is the best way to save energy and for the sake of the planets environment.

if the southern latitudes get more sun exposure for longer hours per day than Northern latitudes predict the effects on the animals living in the two locations
Answer:
Date and latitude interact to determine photoperiod, the daily period of daylight. This interaction has important implications for latitudinal migrants for whom daylight may be a resource or for whom photoperiod regulates annual transitions in life‐history stages (i.e. birds).
Using an established formula, we developed user‐interactive, animated models that enable the visualization of how latitude and date determine photoperiod for latitudinal migrants. We also calculated the photoperiodic schedules for a broad range of hypothetical migratory programmes and real migratory programmes newly available through the proliferation of citizen‐science data. This enabled us to infer the limitations some migratory programmes place on mechanisms for photoperiodic regulation of annual breeding.
In the vast majority of cases, the act of migrating elevates annual daylight exposure. This raises the hypothesis that daylight availability selects for latitudinal migration, potentially contributing to its evolution in animals such as diurnal birds with limited time during the spring and summer to feed young. However, photoperiodic mechanisms regulating annual cycles could constrain the evolution of such migrations, depending on how they affect photoperiodic schedules. Most migratory programmes are consistent with known mechanisms of avian photoperiodism, but the range of feasible mechanisms declines for transequatorial migrants, which experience semi‐annual, 180°‐phase‐shifts in their photoperiodic cycles.
Understanding photoperiodic constraints on migration are particularly important in this age of changing latitudinal distributions and phenologies driven by climate change.

As carbon moves throughout earths systems how are different parts of the biosphere(the part occupied by living things) affected?
Answer:
Carbon is an essential factor to the survival of living things.
Explanation:
It is produced as a waste by-product of metabolism in living organisms and combines with oxygen to be released as Carbon Dioxide (CO2).
Plants on the other hand require CO2 to process sunlight and nutrients into energy. They in return release oxygen which is required by animals to break down food.
Factories, businesses, people (as they generate electricity, transport people and goods, etc) release lots of carbon into the atmosphere it also combines with oxygen again to form C02.
The ocean and water bodies also serve as a collecting conduit of CO2, especially where the water temperature is relatively warm. When CO2 is captured by the ocean, it is used by some sea animals to make shells.

What is it called when certain species have evolved such intimate symbiotic
relationships that individuals of either species cannot survive without one another?
a. obligate
b. parasitic
c. mutualistic
d. facultative
Answer:
A. Obligate
Explanation:
An obligate relationship is one where both organisms are interdependent with one another in a way that one cannot survive without the other.
A parasitic relationship is where one organism benefits, and the other is harmed.
A mutualistic relationship is one where both organisms "work together," therefore benefiting one another.
A facultative relationship is where both species benefit off of one another, but are not fully dependent on one another to the point they cannot survive without their symbotic partner.
