What do you mean by Living organisms?Living organisms may be defined as those organisms which can reproduce, breathe, and have a well-defined system for metabolism activity.
Not all living organisms have 46 chromosomes, 23 homologous chromosome pairs, and a well-defined nucleus.
Therefore, the statement which is true of every living organism is DNA is made of four types of nucleotides.

mechanical, kinetic, potential, gravitational, thermal, chemical, electrical, light, radiant, sound, and nuclear.
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.

16. The substances that are reabsorbed did not diffuse (move) from the nephron bowl into the
renal vein cup. You needed to use lots of energy to make reabsorption happen. Which
process do you think the kidney uses to transport these substances from the nephron to the
renal vein-active transport or diffusion (passive transport)? Explain your answer.
Answer:
Active transport.
Explanation:
The kidney uses active transport to move these substances from the nephron to the renal vein because these substances did not moves from the nephron bowl to the renal vein through simple diffusion so for this purpose active transport is used in which energy is spent in order to move the substances from one region to another so we can say that kidney must use active transport to move reabsorbed substances from the nephron to the renal vein.

A student is investigating mechanical and electromagnetic waves. She is creating a list of questions to include in her investigation about the properties of each type of wave. Which is NOT a question that she can ask that will allow her to learn about the properties of both mechanical and electromagnetic waves?
A
What is the amplitude of the wave?
B
What is the frequency of the wave?
C
What is the wavelength of the wave?
D
What is the wave speed in a vacuum?
Answer:
It would be B
Explanation:
I am sorry if it is wrong
"What is the frequency of wave?" is not a question that she can ask. Thus, the correct option is B.
What is the frequency of wave?Wave frequency is the number of waves which pass through a fixed point in a given amount of time. The SI unit for wave frequency is the hertz (Hz). One hertz (Hz) equals 1 wave passing a fixed point in the time period of 1 second. A higher-frequency wave has more energy than a lower-frequency wave with the same magnitude of amplitude.
The equation used for determination of wave frequency (f) will be:
f = v/λ
where λ is the wavelength in meters and v is the speed of the wave in m/s.
Therefore, the correct option is B.

Explanation:
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.

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.

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.
