Question: what is the sum of the first 100 whole numbers?? how am i supposed to work this out efficiently? thanks

The question you asked relates back to a famous mathematician, Gauss. In elementary school in the late 1700’s, Gauss was asked to find the sum of the numbers from 1 to 100. The question was assigned as “busy work” by the teacher, but Gauss found the answer rather quickly by discovering a pattern. His observation was as follows:

1 + 2 + 3 + 4 + … + 98 + 99 + 100

Gauss noticed that if he was to split the numbers into two groups (1 to 50 and 51 to 100), he could add them together vertically to get a sum of 101.

1 + 2 + 3 + 4 + 5 + … + 48 + 49 + 50

100 + 99 + 98 + 97 + 96 + … + 53 + 52 + 51

1 + 100 = 101

2 + 99 = 101

3 + 98 = 101

.

.

.

48 + 53 = 101

49 + 52 = 101

50 + 51 = 101

Gauss realized then that his final total would be 50(101) = 5050.

The sequence of numbers (1, 2, 3, … , 100) is arithmetic and when we are looking for the sum of a sequence, we call it a series. Thanks to Gauss, there is a special formula we can use to find the sum of a series:

S is the sum of the series and n is the number of terms in the series, in this case, 100.

Answer:

Final pressure, P2 = 362.26 kPa

Explanation:

Given the following data;

Initial volume = 32.5 Liters

Initial pressure = 45.7 kPa

Final volume = 4.1 Liters

To find the final pressure, we would use Boyle's law;

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by;

[tex] PV = K[/tex]

[tex] P_{1}V_{1} = P_{2}V_{2} [/tex]

Substituting into the equation, we have;

[tex] 45.7 * 32.5 = P_{2} * 4.1 [/tex]

[tex] 1485.25 = 4.1P_{2} [/tex]

[tex] P_{2} = \frac {1485.25}{4.1}[/tex]

[tex] P_{2} = 362.26 [/tex]

Final pressure, P2 = 362.26 kPa

hello your question is incomplete attached below is the screenshot of the missing part

answer : The treatment had an effect on the growth of the trees

Explanation:

H0 : No significant effect

Ha : At least one treatment has a significant effect

To confirm the above hypothesis ( conduct one way ANOVA )

From the one way Anova

( X represents each group; from control to Fertilizer and irrigation )

∑ X1^2  = 0.2338 ,  ∑ X2^2 = 1.8284,   ∑X3^2 = 0.1982, ∑X4^2 = 11.8492

Also : ∑ N = 5 + 5 + 5 + 5 = 20  where N = number of  trees in each group

also K represents number of groups i.e. = 4

Next calculate the sum of squares ( calculated using online tools )

i) Between sum of squares:  value = 4.6824

ii) Within sum of squares : value = 4.3572

Next step : Calculate the degrees ( DF)

i) Between degrees of freedom

Dfb = k - 1  where K = 4   therefore Dfb = 3

ii) within degrees of freedom

Dfw = N - k , where N = 20  and K = 4 therefore Dfw = 16  

Next : calculate mean sum of squares

i) Between mean sum of squares

= 4.6824 / 3 = 1.5608

ii) within mean sum of squares  

= 4.3572 / 16 = 0.2723

Calculate the F-statistic value

[tex]F_{calculated }[/tex] = Between mean sum of squares  / within mean sum of squares

= 1.5608 / 0.2723 = 5.73

determine the F critical value

Fcritical = [tex]F_{3,16,0.05}[/tex] = 3.2389  ( obtained from F table )

since [tex]F_{calculated } > F_{critical}[/tex]   hence we can say The treatment had an effect on the growth of the trees i.e. Reject H0

Answer: Sudden loss of habitat

Explanation:

Endangered species are animal or plant species that are in danger of going extinct.

This usually results from them suddenly losing their habitat and thus being exposed to unfamiliar conditions or threats that could end their existence. For instance, elephants losing their forest habitats in India and thus encroaching on farmland only to get shot for damaging farms.

Complete question:

ATP synthesis in chloroplasts is very similar to that in mitochondria: Electron transport is coupled to the formation of a proton (H+) gradient across a membrane. The energy in this proton gradient is then used to power ATP synthesis.

Two types of processes that contribute to the formation of the proton gradient are:

processes that release H+ from compounds that contain hydrogen, and

processes that transport H+ across the thylakoid membrane.

Drag the labels to the appropriate locations on the diagram of the thylakoid membrane. Use only the blue labels for the blue targets, and only the pink labels for the pink targets.

Note: One blue target and one pink target should be left empty.

You will find the image and the labels in the attached files

Answer:

You will find the image and the answer in the attached files

Explanation:

Fosforilation of ADP to ATP occurs while electrons descend through the electron chain, from photosystem II to photosystem I.

Placed in the thylakoid membrane, there are molecules and complexes that participate in light-dependent reactions. The places that occupy these molecules in the membrane make possible ATP synthesis. Protons are released into the thylakoid space when the water molecules split in photosystem II. Membranes are impermeable to protons, so they can not leave the thylakoid space, nor enter without a protein transporter. Through the membrane, there is an electrochemical gradient as additional protons are pumped from the stroma to the thylakoid space, using the released energy as electrons move along the chain. ADP phosphorylates to ATP while protons move from the thylakoid space to the stroma in favor of the electrochemical gradient, through ATP synthase. ATP synthesis occurs in the stroma.

i think answer is D animal in the rain forest

All animals in the rainforest have the same adaptations. Therefore, option C is correct.

A physical or behavioral characteristic of an animal that enhances its ability to survive in its environment is known as an adaptation.

To put it another way, an adaptation is something a person does or has on them that makes it easier for them to locate food, water, mates, and shelter. The structural adaptations made by some plants to survive in hot, dry deserts are one illustration of this.

Animals can defend themselves against predators and extreme weather by adapting. Numerous birds may conceal themselves under long grass, while weeds, insects, and other creatures can alter their colour to blend in. Predators find it challenging to locate them in search of food as a result. Hence, option C is correct.

Answer:

The correct answer is ''undergo irreversible repression.''  

Explanation:

The morphological and physiological transformation of meristematic cells into adult or differentiated tissues constitutes the process of cell differentiation. This, and the consequent specialization of the cell, bring about the division of labor, forming cells with specific functions. Differentiation occurs by differential activation of some genes and repression of others. Depending on the position it occupies, each cell receives certain stimuli to develop the corresponding activities. During the differentiation process, cells undergo a series of changes in their characteristics and there is a readjustment in their mutual relationships.Different molecular factors initiate and drive the programming / reprogramming of cell fate through the modulation of specific genomic and epigenomic patterns, which regulate the expression of activator / repressor genes of the main fundamental and specialized cellular processes. Thus, the differentiated cell will express certain genes and acquire certain functions.Adult stem cells are responsible for maintaining the different types of specialized cells that make up the body. Asymmetric cell division in stem cells has emerged as one of the main physiological mechanisms that regulate the number of cells and their diversity to maintain tissue homeostasis. A large number of molecules, generically called determinants of cell fate, participate in the regulation of asymmetric division. Asymmetric division of somatic stem cells produces both a stem cell and a progenitor. The initial progenitor cells, through new cycles of asymmetric cell division, finally reach their terminal state of cell differentiation, due to changes in intracellular and extracellular (environmental) signaling. After cells leave their mother state and begin to differentiate, they make exclusive selections for phenotypic pathways through secondary genomic / epigenomic modifications, mainly to different types and gradients of transcription factors (physiological programming of cell differentiation). This leads, for example, to activation of specialized biosynthetic pathways, remodeling of the cytoskeleton, and repression of cell proliferation signaling. The expression of genes is regulated mainly at the level of their transcription. Transcription factors correspond to proteins with the ability to interact with specific DNA sequences and trigger their transcriptional activity. Most transcriptional factors contain different domains that participate in different aspects of protein function; they generally contain two domains: a domain that binds to specific DNA sequences and an activation domain that regulates transcription by interacting with other proteins. In the regulation of gene transcription, in addition to transcription factors, coactivating and corepressor molecules participate, which bind to them, modifying their activity in a positive or negative sense. Each cell type has a characteristic pattern of gene transcription, which is determined by the binding of combinations of transcription factors to the regulatory regions of a gene.

Cellular differentiation progressively restricts cell fate because the unexpressed genes in the cell are undergoing irreversible repression.

Gene repression is the switching off of unique genes whose products are needed to support the function of the cell such as the production of vital enzymes or cofactors.

This is specifically important if the products of such genes are not long-lived and deteriorate, or are metabolized.

Thus, option "D" is undergo irreversible repression.

Brain Plasticity

Explanation:

This is an example of the brain's ability to adapt to changes in the body and loss of connections in the brain itself and is not fully understood. This is also why people that loss their vision can have much better hearing months or years later, as their brain adapts to the body's loss of a sense and compensates.

The example given explains neuroplasticity.

Neuroplasticity, is also referred to as brain plasticity and this occurs when there's a change in the nervous system as a result of a response to a particular stimuli.

In this case, the neural networks that are in the brain will change and the changes can bring about systematic adjustments in the body.

Answer:

The expected frequency of the dominant allele, N is 0.70

Explanation:

Total number of individuals in the insect population = 97 + 52 + 50 = 199

From Hardy-Weinberg equation, p2 + 2pq + q2 = 1; also p + q = 1

The frequency of dominant allele, N = p

Frequency of dominant NN genotype individuals = p2

From the given data: the population is comprised of 97 individuals with the NN genotype, 52 individuals with the Nn genotype and 50 individuals with the nn genotype.

Frequency of NN genotype individuals p2 = number of individuals with NN genotype ÷ total insect population

p2 = 97/ 199

p2 = 0.487

p = 0.697 = 0.70

Therefore, the expected frequency of the dominant allele, N is equal to 0.70

Answer:

Urine is more concentrated than initial filtrate. Urine is, in fact, four times more concentrated than initial filtrate.

Explanation:

The urinary system is the one in charge of filtrate blood and propduce urine. The main stars in the system are kidneys and the functional unit of them are the nephrons.

There are many steps in producing urine. Fluid goes between different parts of the kidney: renal tubule, renal corpuscle, bowman's capsule, etc. We have through all these parts these following steps: filtration, reabsorption to blood, secretion from blood and excretion.

From filtrate, the boody reabsorbs sodium chloride, glucose, water and amino acids. When the fluids moves down the loop of Henle, it becomes less concentrated, so it is full of water. At the end, urine is four times more concentrated than initial filtrate.
