Answer:

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

things needed to carry out the photosynthesis:

Chlorophyll. Chlorophyll, the pigment in plants that makes them green, is essential to the photosynthetic process.
Sunlight. The process cannot work without an energy input, and this comes from the sun.
Water

Carbon Dioxide.

The process of photosynthesis is commonly written as:

6CO2 + 6H2O → C6H12O6 + 6O2

This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll into a sugar molecule and six oxygen molecules, the products.

An RN enters a client's room and observes the unlicensed assistive personnel (UAP) forcefully pushing a client down on the bed.

aksik [14]

Answer:

A) Battery.

Explanation:

The RN is witnessing a case of battery because the unlicensed assistive personnel is forcefully pushing a client and is not paying attention to what the person needs, specially in a delicate state where the client needs contention and to be treated extremely well.

Humerus bones from the same species of animal have approximately the same length-to-width ratios. It is known that Species A has

Dima020 [189]

Answer:

The unearthed Humerous bones don't belong to the species A.

Explanation:

Hello!

You are studying the Humerus bones species A, who is known to have a mean ratio of 8,5. This value corresponds to the population mean of the length-to-with ratio of bones of species A, symbolized as μ.

The hypothesis you want to study is "The Humorous bones unearthed belong to the species A" if you assume this to be true, then the mean of the length-to-with ratio should be equal to the known population mean of the length-to-with ratio.

Symbolized:

H₀: μ = 8,5

H₁: μ ≠ 8,5

Significance level: α: 0,05

You are asked to use a Z-test, since you don't know the value of the population variance, but have the sample values, the sample size is big enough (more than n=30). Assuming that the sample values are independent, the statistic test of choice is the approximation:

$Z= \frac{x_bar-μ}{S\sqrt[]{n} }$ ≅N(0;1)

The critical region, in this case, it's a two-tailed test (remember the type is determined by the null hypothesis) so you'll have two critical values.

Left value [/tex] $Z_{\alpha/2} = Z_{0,025} = -1,96$

Right value $Z_{1-\alpha/2} = Z_{0,975} = 1,96So you'll reject the null hyphotesis if the calculated [tex]Z_{obs}$ value is ≤-1,96 or ≥1,96 and you'll support it if -1,96< $Z_{obs}$ <1,96

Now we calculate the statistic by replacing the formula with the data:

x_bar = 9,26

S = 1,20

n = 41

$Z_{obs}= \frac{x_bar-μ}{S\sqrt[]{n} }$

$Z_{obs}= \frac{9,26-8,5}{1,20\sqrt[]{41} }$

$Z_{obs}$ = 4,0553

Since the calculated value falls in the rejection region, this means, you have statistically significant results. In other words you can reject the null hipothesis (H₀: μ = 8,5) and asume that the unearthed Humerous bones don't belong to the species A.

I hope you have a SUPER day!

Which of the following wave properties is the best way for surfers to judge how fast waves are coming in to shore?

Lemur [1.5K]

Answer;

-Frequency

Explanation

-Wave frequency is the number of waves that pass a fixed point in a given amount of time. The SI unit for wave frequency is the hertz (Hz), where 1 hertz equals 1 wave passing a fixed point in 1 second. A higher-frequency wave has more energy than a lower-frequency wave with the same amplitude.

-The speed of a wave is dependent on four factors: wavelength, frequency, medium, and temperature. Wave speed is calculated by multiplying the wavelength times the frequency. Since speed is constant within the same medium, a high frequency has a short wavelength and vice-a-versa

Describe the general flow of energy through an ecosystem beginning with the Sun and going through a third order consumer.

Illusion [34]

Answer:

1) Autotrophs transform solar energy into chemical energy.

2) Herbivores and omnivores (primary consumers) eat producers, make use of some of the energy, making from it their biomass.

3) Following, carnivores or predators (secondary, tertiary, and other consumers) eat herbivores, using only 10% of the flowing energy.

4) Decomposers (last order in the chain) recycle all the dead organic material and make use of some of the stored energy.

Explanation:

<u>Energy flow: </u>From the whole quantity of energy that reaches the earth's surface, only 0.1 or 1% is absorbed by autotroph organisms or producers.

From this input of solar energy, it begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is finally dissipated in the environment.

Organisms that can use light, and turn it into organic matter according to their own needs are producers, and they are called autotrophic organisms. These organisms are by excellence all plants, algae, and bacteria that photosynthesize. Organisms that are incapable of producing their food are called heterotrophic. They depend on other organisms from the trophic chain such as plants or other animals to feed on, so they can get proteins and energy. In the trophic web, heterotrophic organisms occupy the first, second, or third consumer level, after producers. There are different types of heterotrophic animals: carnivorous, herbivorous, omnivorous, hematophagous, ichthyophagous, and etcetera. All of them depend on autotrophic organisms.

At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called <u>"The 10% rule".</u> This is, as a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time.

The progressive reduction of energy determines the number of trophic levels in the chain (4 or 5).

1) Autotrophs use water, CO2, and solar energy to produce O2 and glucose, by the process of photosynthesis and convert it into biomass. Producers transform solar energy into chemical energy.

2) Herbivores and omnivores (primary consumers) make use of some of this energy to survive, making from it their biomass. The rest of the energy is lost.

3) Following, carnivores or predators (secondary, tertiary, and other consumers) eat herbivores, using only 10% of the flowing energy. The rest of the energy is lost.

4) When different organisms die, decomposers (last order in the chain) recycle all the organic material and make use of some of the energy stored in their tissues. The rest is lost.

Which best describes what is occurring in this population of squirrels? Number of Squirrels Entering and Leaving a Population af

Aleksandr-060686 [28]

Answer:

Explanation:

The population of squirrel is decreasing and this can be traced to the environment not being favorable for their growth and development.

Looking at the data generated,

Died from predation =2

Born=4

Immigration=10

Left to find food =3

Died from disease=8

Left to find mate=3

If all the squirrel did not abandon their habitat and they all live there a total of 2+4+10+3+8+3= 30 squirrel would have been present, but given that only 4 were born and that others left for another place the population is reduced to 4 and 26 squirrel gone this has lead to a reduced population.
