Answer:

46 chromosomes

Explanation:

There are 46 chromosomes in a typical human body cell. (23 pairs of chromosomes)

how many chromosomes are in a typical human body cell?

46 chromosomes

The normal number of chromosomes in every cell of a typical human body is a total of 46 chromosomes, or 23 pairs.

Answer:a

Explanation:

Answer:

true

Explanation:

The sodium and chloride ion concentrations are lower inside the cell than outside, and the potassium concentration is greater inside the cell. These concentration differences for sodium and potassium are due to the action of a membrane active transport system which pumps sodium out of the cell and potassium into it.

First we need to determine the average atomic mass of these isotopes.

The atomic masses of Lithium-6 and Lithium-7 are 6.0151amu and 7.0160amu respectively.

Now that we have that, we need to set up the relative abundance problem.

We can do that using the formula (M1)(x) + (M2)(1-x) = M(E)

Because you asked for details, I'll explain what each variable stands for-

M1 = the mass of one isotope

x = the relative abundance

M2 = the mass of the second isotope

M(E) = the atomic mass of the element from the periodic table

Therefor all we do now is plug in our respective variable.

M1 = 6.0151amu (Lithium-6)

x = unknown relative abundance

M2 = 7.0160amu (Lithium-7)

M(E) = 6.94004amu

Now the formula plugged in will look like this:

6.0151x + 7.0160(1-x) = 6.94004

Now doing some quick math, we can determine that x=0.07589

For the last step we need to find the percent abundance of each element, which is quite simple. We take X and multiply it by 100 to find Lithium-6, so 0.076 x 100 = 7.6%

and since then we use 1 - X, so 1 - 0.076 = 0.924

We take that and also multiply it by 100, so 0.924 x 100 = 92.4%

Conclusion:

The abundance of the Lithium-6 isotope is 7.6%, and the abundance of the Lithium-7 isotope is 92.4%.

Answer:

All of the above.

Explanation:

All of these can contribute to sediment accumilation in bodies of water.

Sedimentation accumulation found in water bodies can be the result of fertilizer runoff, pesticides, pesticides, and erosion from agricultural practices. So, the correct option is D.

The sedimentation accumulation may be defined as a process of gathering sediments into the rocks, and water bodies, and increasing their actual mass.

Sedimentation accumulation may be carried by the runoff of fertilizers, pesticides, and insecticides. It also occurred due to the process of soil erosion that takes place during agricultural practices.

Therefore, the correct option for this question is D.

Answer:

The answer is D. At the top of the swing where it briefly stops before changing direction.

Explanation:

When the pendulum is either at its far right or left position, the bob is at rest and therefore its kinetic energy is equal to zero- making it the lowest point of kinetic energy during the whole process.

Answer:

The answer is C

Explanation:

because when your on the swing the most kinetic energy is where you start to go to the upwards part right when the drop happens

it allows you to swing up very high making the option C correct

Structure. As a plant's reproductive part, a flower contains a stamen (male flower part) or pistil (female flower part), or both, plus accessory parts such as sepals, petals, and nectar glands (Figure 19). The stamen is the male reproductive organ. It consists of a pollen sac (anther) and a long supporting filament.

Producers are described as autotrophic, which means they are able to make their own food. Just like producers on land, producers in the marine environment convert energy from the sun into food energy through photosynthesis.

Explanation:

Adenine (A) and Thymine (T) pair together. Cytosine (C) and Guanine (G) pair together.

With mRNA, the RNA doesn't have Thymine, so it replaces it with Uracil (U).

The canopy cover can affect the results of an investigation because a higher canopy cover is accompanied by a decrease in the availability of sunlight.

The canopy cover is the proportion of the ground covered by vegetation when it is viewed from vertically above the planted area.

The level of canopy cover affects light availability on the ground and also its microclimate, thereby this feature can also alter any biological experimental procedure by affecting the level and type of biodiversity.

A reduced canopy cover may alter any experimental outcome by increasing the energy/light input in the ground cover stratum, thereby likely affecting biodiversity.

Explanation:

The wings in birds and insects are not considered as evidence of relatedness because they differ in structures even though their functions may be the same.

Organs in different organisms that are different in structures but similar in functions are referred to as analogous organs. Even though analogous organs serve as evidence of organic evolution, they are indications that organisms differ in the paths taken to evolve.

Some other organs may be similar in structures but different in functions. These types of organs are known as homologous organs and are indications that organisms are kind of related in the path taken to evolve.
