Name 5 high energy substrates of metabolism in the order of their energy of hydrolysis

Water. Water is responsible for the formation of landforms like rivers, valleys, canyons, and deltas.

What are Landforms?

Landforms are natural features of the Earth's surface, such as valleys, mountains, plains, plateaus, hills, and coasts. They are formed by geological processes, such as erosion, volcanic activity, tectonic movements, and deposition. Landforms can vary in size from tiny ripples in the sand to large mountain ranges.

Wind can carry sediment and erode existing landforms, but it is water that is mainly responsible for the formation of landforms. Plants and animals can influence the formation of landforms, but not to the same extent as water.

Hence, Option B is correct.

Answer:  4

Explanation:

Properties of Ionic and Covalent Compounds are given below.

Transfer/Sharing of Electrons:

Ionic compounds involve the transfer of electrons from one atom to another. Covalent compounds involve the sharing of electrons between two atoms.

Structures/ Shapes of Molecules:

Ionic compounds tend to form crystalline structures, while covalent compounds tend to form more complex and varied structures.

Hardness/Brittleness:

Ionic compounds tend to be brittle and are not malleable, while covalent compounds tend to be softer and more malleable.

Electrical Conductivity:

Ionic compounds tend to be electrical conductors in their solid state, while covalent compounds tend to be electrical insulators.

Melting/Boiling Points:

Ionic compounds tend to have higher melting and boiling points than covalent compounds.

Electronegativity & Polarity:

Ionic compounds are basically more polar than covalent compounds due to the unequal sharing of electrons.

Octet Rule:

The octet rule states that atoms tend to form covalent bonds in order to achieve an electron configuration of eight electrons in their outermost energy level. This is due to the stability of the noble gas configuration. Exceptions to the octet rule include molecules with an odd number of electrons, molecules with more than eight electrons in the outer shell, and molecules with expanded octets. Examples of these exceptions include BF3, PCl5, and SF6.

Lewis Dot Structure:

A Lewis dot structure is a diagram that represents the outermost electrons of an atom. It is drawn by placing dots representing the electrons around the chemical symbol of the element. This diagram is used to determine the geometry of the molecule and to predict the type of bonds that can form between atoms.

VSEPR:

VSEPR stands for Valence Shell Electron Pair Repulsion. It is a model that predicts the geometry of a molecule based on the number of electron pairs present around the central atom. A lone pair is a pair of electrons not shared between two atoms and is represented by two dots in a Lewis dot structure. Examples of compounds with lone pairs include water (H2O), ammonia (NH3), and sulfur dioxide (SO2).

The molecular shapes without any lone pairs are linear, trigonal planar, tetrahedral, and trigonal bipyramidal. The general formula without any lone pairs is AXn, where n is the number of atoms bonded to the central atom. Examples include CO2 (linear), BF3 (trigonal planar), CH4 (tetrahedral), and PCl5 (trigonal bipyramidal).

The molecular shapes with lone pairs are bent, trigonal pyramidal, T-shaped, and square planar. The general formula with any lone pairs is AXnE, where n is the number of atoms bonded to the central atom and E is the number of lone pairs. Examples include H2O (bent), NH3 (trigonal pyramidal), IF3 (T-shaped), and XeF4 (square planar).

What is a Covalent bond?

A covalent bond is a type of chemical bond formed when two atoms share a pair of electrons. This type of bond is generally formed between two non-metallic atoms, such as two oxygen atoms, or between two different elements. Covalent bonds are strong, stable, and tend to form molecules.

Answer:

2, burning fossil fuels

Explanation:

When fossil fuels such as coal, oil, and natural gas are burned, they release carbon dioxide into the atmosphere. This process increases the concentration of carbon dioxide in the air, which is a greenhouse gas that can trap heat and contribute to global warming.

Chemical equations may only be balanced by changing the coefficients; subscripts cannot be changed. The ratios of the atoms in the molecule and the resulting chemical characteristics alter when subscripts are changed.

Place coefficients in front of symbols or formulas as necessary to balance chemical equations so that the same number of each type of atom appears in both reactants and products.

Therefore,To indicate the unknown coefficients, give the equation a variable name for each chemical (reactant or product).

Tiktaalik, an extinct fish species, could have existed in a Canadian environment due to the presence of shallow freshwater environments with low oxygen levels, which would have been suitable for its lung-like structure and ability to breathe air.

Tiktaalik is an extinct genus of fish that lived about 385 million years ago during the Late Devonian period. It is considered a transitional fossil, as it has characteristics of both fish and early tetrapods, four-legged land-dwelling animals. Tiktaalik could have existed in a Canadian environment, as it is known to have been found in the Canadian Arctic, specifically in the Elpistostege watsoni fossil beds of the Nunavut territory.

The environment during Late Devonian period in this region was a shallow freshwater delta or coastal plain that was home to a diverse array of fish and other aquatic organisms. Tiktaalik likely lived in the shallow water, and had adaptations such as flexible neck and fins with bones that resemble the limb bones of four-legged animals, which would have allowed it to move in shallow water and on land.

Answer:

a

Explanation:by ages and physical similarities

Answer:

D. The allele frequencies will remain the same as they were in the parent population.

Explanation:

In population genetics, the Hardy-Weinberg equilibrium predicts that genotype and allele frequencies will remain constant from one generation to the next. The Hardy-Weinberg principle has five major assumptions: random mating, no mutation, no gene flow, infinite population size, and no selection. In a population, genetic change can be measured as a change in genotype frequencies or allele frequencies, but a type of change does not necessarily imply a change in the other. In this case, the frequency of alleles in the pool of male and female gametes (sperm and eggs, respectively) that meet to make the next generation will be the same, but genotype frequencies change from one generation to the next.

The five conservation related conventions are:

1. Convention on Biological Diversity

2. Convention on International Trade in Endangered Species of Wild Fauna and Flora

3. Convention on Migratory Species

4. Ramsar Convention on Wetlands

5. Convention on the Conservation of Antarctic Marine Living Resources

The Convention on Biological Diversity is the most embracing of these conventions, as it provides the most comprehensive coverage of conservation related issues. Its focus is on the conservation of biodiversity, sustainable use of resources, and the fair and equitable sharing of benefits arising from the use of genetic resources. Additionally, it provides strategies and commitments to ensure that exploitation of living resources is done with sustainability and responsibility, bringing it into line with the principles and goals of ecological conservation.

Here the physical changes are seen in the burning candle, cooling candle, tearing paper, wet paper, salt, and water in the test tube, while the chemical reactions are involved in the burning of the paper and the mixing of the vinegar with soda.

The physical change is the change in form, such as when the candle is burned or cooled down, then the wax that is formed has the same properties as the candle, or the paper pieces after being torn have the same properties. Chemical changes involve the formation of new things, such as when paper is burnt, this produces ash with a different chemical nature, and when the vinegar and soda is mixed, it produces a different product.

Answer: The correct option is A (Segmentation waves; food to move backward and forward; peristalsis; food to move along the tract distally).

Explanation:

Gastrointestinal motility is defined as the different activities carried out by the smooth muscles of the tract which Involves it's contraction and relaxation to bring about the movement of ingested food through the gut for absorbing nutrients, water,electrolytes and eliminating waste products. These movements can be divided into two namely:

--> Mixing Contractions: These contractions are also called the SEGMENTATION WAVES. When a portion of the small intestine becomes distended with chyme, stretching of the intestinal wall elicits localised concentric contraction spaced at interval along the intestine causing segmentation of the small intestine. These contraction causes the movement of chyme BACKWARD and FORWARD which allows greater mixing with the secretions of the intestines.

--> Propulsive Contractions: These contractions are also called peristaltic waves. Bands of muscles in the walls of the gastrointestinal tract contract and relax alternately to push each bolus of food downwards slowly. This process is known as PERISTALSIS. This occurs in all regions of the tract causing the movement of food towards the anus (distal direction).

Therefore, gastrointestinal motility includes Segmentation waves which causes food to move backward and forward, and peristalsis; which causes food to move along the tract distally.
