Explanation:

Answer:

- The flow of energy is from the lowest level (i.e., the base of the pyramid)  to highest levels

- Approximately 10 percent

Explanation:

The energy pyramid is a diagram that shows the flow of energy between trophic levels in an ecosystem. Each trophic level is characterized by organisms that play specific roles in an ecosystem, for example, photosynthetic organisms (producers) at the base of the pyramid which represent the source of energy for herbivores localized at a higher level. The amount of energy decreases as it moves to higher trophic levels, approximately 10 percent of the energy is transferred from a trophic level to the next level and the remaining energy is lost as heat.

Fossil fuels are formed when mineral deposits are recrystallized due to high temperature and pressure over time.

Fossil fuels are formed when mineral deposits are recrystallized due to high temperature and pressure over time.

Explanation:

How are fossil fuels formed from geologic processes? Fossil fuels are formed when mineral deposits are recrystallized due to high temperature and...

ANSWER

Fossil fuels are formed when biomass is covered by sediment, and the biomass experiences high temperature and pressure over time. The correct option is B.

Coal, oil, and natural gas are fossil fuels formed from the remains of dead plants and animals that were buried in sedimentary rock layers millions of years ago.

Over time, these organic materials are subjected to high temperatures and pressure, resulting in the transformation of organic matter into fossil fuels.

These hydrocarbons migrate through the surrounding rock over millions of years and accumulate in underground reservoirs, where they can be extracted and used as energy sources.

Fossil fuel formation is a slow process that requires specific geological conditions such as the presence of sedimentary rocks, high temperature, and pressure.

Thus, the correct option is B.

Answer:

Mendel's law of independent assortment states that the alleles of two (or more) different genes get sorted into gametes independently of one another. In other words, the allele a gamete receives for one gene does not influence the allele received for another gene. Let's look at a concrete example of the law of independent assortment.

Eukaryotic Cell

Explanation:

Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA.

Answer:

1,3 and 5.............

Answer:

A

Explanation:

When the population is well below the carrying capacity, it results into Logistic Growth.

As competition increases and resources become increasingly scarce, populations reach their carrying capacity causing growth rate to slow nearly to zero.

This produces an S-shaped curve of population growth known as the Logistic Curve.

Resources important for the survival of the species can act as a factor for Carrying Capacity .Example- For plants , it is water, sunlight, nutrients and space and for Animals- Food, Water, Shelter and Nesting Space.

Limited quantities of these resources results in competition between members of the same population or Intraspecific competition.

Examples of Logistic Growth are:

Yeast - A microscopic fungus can produce S shaped curve when grown in test tube.

Logistic Growth takes place when population's per capita growth rate decreases as population size approaches a maximum imposed by limited resources i.e. the carrying capacity.

Ecologists uses different methodologies for modelling Population Dynamics, amongst which major ones are Exponential Growth and Logistic Growth.

When the per capita rate of increase takes the same positive value regardless of the population size, it results into Exponential Growth whereas the per capita rate of increase decreases as the population increases towards a maximum limit, then we get Logistic Growth.

Similarities Between DNA and RNA

Both DNA and RNA store genetic information. DNA and RNA are both large biological polymers. Both DNA and RNA consists of sugar, nitrogenous bases, and a phosphate backbone. On both molecules, guanine and cytosine pair with each other (are complementary).

Explanation:

Answer:

b. tubulin

Explanation:

Tubulin is a superfamily of proteins that make up microtubules who have many functions including intracellular trasport of neuron's vescicles

Tubulin protein is damaged at the nerve endings during mercury toxicity.

Mercury toxicity occurs when an individual is highly exposed to mercury.

The inhalation of mercury vapor can produce harmful effects on the nervous, digestive and immune systems, lungs, and kidneys, and may be fatal. This is considered as one of the severe toxicity that a person suffers.

Tubulin proteins are a very important class of proteins that helps in the formation of microtubules that have numerous functions in our body including the cytoskeletal arrangement of cells, intracellular transport of neuronal vesicles. And when a person suffers from mercury toxicity, such proteins are damaged and result in improper conduction of nerve impulses.

Therefore, Tubulin protein is damaged at the nerve endings during mercury toxicity.

Answer:

2.4 × 10⁻⁶ M

Explanation:

Molar concentration = no of moles of solute (enzymes)/volume of solvent(cystosol)

Let V = volume of solvent = volume of cystosol = πd²h/4 where d = diameter of cell = 1.0 m and h = height of cell = 2.0 m

Concentration of enzymes, C = n/V where n = no of moles of enzymes

Also, n = m/M where m = mass of all enzymes and M = molecular weight of protein = 100,000

Note that the solvent for the enzymes is cystosol, since they are dissolved in it.

Density of cystosol,ρ = specific gravity of cystosol in g/cm³ = 1.20 g/cm³.

Now, ρ = m'/V where m = mass of cystosol and V = volume of cystosol

m' = ρV

m' = 1.20V

Given that 20 % of the cystosol is protein and all protein are enzymes, the mass of enzymes is thus m = 0.2m' = 0.2 × 1.20V = 0.24V

C = n/V

= m/MV

= 0.24V/100000V

= 2.4 × 10⁻⁶ mol/cm³

= 2.4 × 10⁻³ mol/dm³

= 2.4 × 10⁻³ M

This is the concentration of all the 1000 enzymes.

So, the concentration of one enzyme is 2.4 × 10⁻³/1000 M = 2.4 × 10⁻⁶ M

Answer:

D. Layer B

Explanation:

The correct answer is Layer B.

The law of superposition actually states that the sedimentary rock unit is at the bottom while the the youngest rock is at the top.  The principle of cross-cutting relationships states in layers of rocks, a fault or intrusion that cuts through rock layers is younger than the rocks that it cuts through.

Layer B was actually formed after Layer C. This makes Layer B younger than Layer C and closest in age to Layer C. The intrusion, Layer D is the youngest of all.
