Answer:
Lateral Malleolus and medial malleolus. The lateral malleolus is comprised of the talus and fibula. The medial malleolus is comprised of the talus and tibia.
Explanation:
hello:)
The fibula, tibia, and talus, the three bones that make up the ankle joint, can all break if you fall or get a hit to the area.
What are the functions of bone of ankles?The subtalar joint, which is located below the ankle joint, permits the foot to move from side to side.
The true ankle and subtalar joints are surrounded by a network of ligaments, which are strong, flexible tissues that connect the bones of the leg to those of the foot.
The responsibility for ensuring the body's balance and stability falls on the ankles. Ankles are positioned to absorb friction brought on by various bodily movements.
Therefore, The talus and fibula make up the lateral malleolus. The talus and tibia are part of the medial malleolus.

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.

Rippling waves; food to move backward and forward; segmentation; food to move along the tract distally. D. Propulsion waves food to move backward and forward; peristalsis; food to move along the tract distally. E. None of the above
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.

3. Identify and describe the molecular shapes. Give general formula without any lone pairs and examples.
4. Identify and describe the molecular shapes. Give general formula with any lone pairs and examples.
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.

The individuals of this population mate randomly and never move (i.e., there is no migration into or out of the population), and mutation also does not occur. Each couple has two children and the parents die after having their second child, so the population size does not change. Answer the questions about this population after the parents have had both children and are dead. Which is true about the next generation of this population?
A. The genotypic frequencies will remain the same as they were in the parent population.
B. The genotypic frequencies will be double of what they were in the parent population.
C. The allele frequencies will be double what they were in the parent population.
D. The allele frequencies will remain the same as they were in the parent population.
E. Both genotypic and allele frequencies will remain the same as they were in the parent population.
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.
