Grassland biome has a cold harsh climate and short growing season.

Grasslands can be found in regions with regular rainfall levels that are insufficient for a forest to thrive but not so low that a desert develops. Indeed, meadows are frequently found between deserts and woods. Grasslands cover anywhere from 20 to 40% of the planet's geographical area, depending on how they are characterized.

They exist on every continent, with the exception of Antarctica, and are often open and flat, making them susceptible to pressure from burgeoning human populations.

Agriculture, excessive grazing, invasive species, unreported hunting, and climate change are some of the threats to natural grasslands and the wildlife that inhabits them.

Therefore, Grassland biome has a cold harsh climate and short growing season.

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: 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.

Answer:

Explanation:

Irreversible inhibitors usually react with the enzyme and change it chemically (e.g. via covalent bond formation)

In contrast, reversible inhibitors bind non-covalently and different types of inhibition are produced depending on whether these inhibitors bind to the enzyme, the enzyme-substrate complex, or both.

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.

Answer:

fats, starches, sugars

Carbohydrates are fats, starch, and sugars. Thus, option A, C, and D are correct.

Carbohydrates is defied as that contains biomolecule that contains carbon hydrogen and oxygen in a ratio of 2:1.

Carbohydrates are mane source of energy of the body they work as fuel for the brain, kidneys central nervous system and heart muscle.

Cn(H2O)n is the basic formula for all carbohydrates . But this formula have limitation i.e it applies where same amount of carbon and water are use.

Initially the terms carbohydrate was used to describe compounds that have really contains carbohydrates because they had simple formula CH20.

In modern era carbohydrates are classified on the basis of their structure not on their formulae. Such as aldehydes and ketones are now known as polyhydroxy.

Therefore,carbohydrates are fats, starch, and sugars. Thus, option A, C, and D are correct.

Explanation:

Little or no humidity is not so true anymore, with the building up and more greenery. Las Vegas the humidly is not at all that low as it once once

The difference in humidity between Florida and Las Vegas is primarily due to their geographic locations and climate patterns.

Florida is located in the southeastern United States and is surrounded by water on three sides, with the Atlantic Ocean to the east, the Gulf of Mexico to the west, and the Straits of Florida to the south.

This proximity to water and the warm ocean currents that flow nearby create a humid subtropical climate, characterized by hot summers and mild winters with high levels of humidity throughout the year.

The low humidity in Las Vegas is due to the fact that the dry air has little moisture in it, leading to a lower amount of moisture in the atmosphere. Thus, there is a difference in humidity between Florida and Las Vegas.

Answer:

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:

The trends go up in the presence of nutrients.

Explanation:

There is a great relationship between nutrients and photosynthesis because photosynthesis can't occur without without the availability of nutrients. Plants uses carbon from the atmosphere which is a nutrient whereas other nutrients such as nitrogen, phosphorus, potassium etc from the soil with the help of the roots. If these nutrients are available in the surrounding, the plant produced more food during photosynthesis because these nutrients are the food of plants so the trends go up in the presence of nutrients and lowers down in the absence or lower concentration of nutrients.

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
