In asexual reproduction, genetic information comes from only one parent; whereas, in sexual reproduction, genetic information from two parents to form an offspring.

Asexual reproduction is a type of mechanism by which only one parental organism may produce offspring and therefore it is not associated with the formation of gametes.

In sexual reproduction, the cells from different parents having half genetic material fuse to produce an egg that will develop into an adult organism by a process known as fertilization.

The different types of asexual reproduction in organisms include, among others, vegetative propagation, binary fission (bacteria), Budding, fragmentation division, reproduction by spores (sporogenesis), etc.

In conclusion, in asexual reproduction, genetic information comes from only one parent; whereas, in sexual reproduction, genetic information from two parents to form an offspring.

Taking into account the definition of molarity and molar mass, the correct answer is option a: 1.11 mL of 0.5 M glucose (molecular mass 180) is needed to provide 100 mg of glucose.

Molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by :

molarity= mass÷ volume

Molarity is expressed in units moles/L.

The molar mass of substance is a property defined as the amount of mass that a substance contains in one mole.

In this case, you have:

You can apply the following rule of three: If by definition of molar mass 180 grams of glucose are contained in 1 mole, 0.1 grams of glucose are contained in how many moles?

amount of moles= (0.1 grams× 1 mole)÷ 180 grams

amount of moles= 5.556×10⁻⁴ moles

Noe, replacing in the definition of molarity:

0.5 M= 5.556×10⁻⁴ moles÷ volume

Solving:

0.5 M× volume= 5.556×10⁻⁴ moles

volume= 5.556×10⁻⁴ moles ÷0.5 M

volume=1.11×10⁻³ L= 1.11 mL (being 1 L= 1000 mL)

Finally, the correct answer is option a: 1.11 mL of 0.5 M glucose (molecular mass 180) is needed to provide 100 mg of glucose.

Answer: withdrawal of red blood cells

Explanation:

Achondroplasia is an inherited conditions that impedes long bones growth resulting in dwarf phenotype. The mode of inheritance is complete dominance, expressing a phenotypic ratio = 3:1.

Achondroplasia is a congenic condition genetically determined. Individuals expressing this condition do not have normal bone development. They are short in height, with short extremities and macrocephaly.

A mutation in the gene FGFR-3 is responsible for this condition, affecting mainly long bone growth. Normal parents can have a dwarf son or daughter.

The inheritance pattern of this condition is complete dominance, meaning that an autosomal dominant allele is responsible for achondroplasia expression.

If two individuals with achondroplasia have at least one normal child it means that both parents are heterozygous for the trait, and both of them transmitted the recessive allele to the normal child. Let us see,

We will name,

Cross: two individuals with achondroplasia

Parentals)  Aa   x    Aa

Gametes) A   a      A    a

Punnett square)  A     a

                      A   AA   Aa

                       a  Aa     aa

F1) 1/4 = 25% of the progeny is expected to be homozygous dominant AA and express achondroplasia

    2/4 = 1/2 = 50% of the progeny is expected to be heterozygous Aa and express achondroplasia

     1/4 = 25% of the progeny is expected to be homozygous recessive aa and express the normal phenotype (wild type).

The phentoypic ratio is 3:1.

Now let us talk about the ratios,

4 possible genotypes -------------------- 3 individuals among the progeny

3 dwarf genotypes ------------------------X = (3 x 3) / 4 = 2.25 ≅ 2

1 wild type genotype --------------------- X = (1 x 3) / 4 = 0.75 ≅ 1

The phenotypic ratio of the progeny approximates 3:1.

The phenotypic ratio of 3:1 is typical of complete dominance.

Imprinting takes place at a 'critical period'; if imprinting does not take place in time, the goslings do not attach themselves to a mother figure.

Imprinting, initially described by naturalist Konrad Lorenz in the 1930s, happens when an animal creates a connection to the first item it sees after hatching. Lorenz noticed that newly hatched goslings would flock to the first moving item they encountered, which was frequently Lorenz himself.

Despite being of a different species, Lorenz was able to persuade geese to imprint on him as their mother. Lorenz studied imprinting by observing animals in their natural surroundings. He also used the technique of empathising with animals.

Almost every eukaryotic organism, including plants and animals, has mitochondria in its cells.

2) a) Photosynthesis: 6CO2 + 6H2O → C6H12O6 + 6O2.

   b) Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O

3) a) Mitochondria Release energy for the cell.

   b) carbon dioxide and water Is made during respiration.

4) Water and carbon dioxide are changed into oxygen and glucose during photosynthesis. The plant consumes glucose and produces oxygen as a byproduct. Oxygen and glucose are transformed into water and carbon dioxide during cellular respiration. By-products of the process include carbon dioxide, water, and ATP, which are turned into energy.

The main purpose of photosynthesis is to transform solar energy into chemical energy, which is then stored for later use. This mechanism primarily provides energy to the planet's life systems. The C3, C4, and CAM pathways are the three basic categories of photosynthetic pathways. They all use the Calvin cycle to convert CO2 into sugars, but each pathway does so in a somewhat different way.

The hermaphroditic nematode Caenorhabditis elegans has a mapped somatic lineage that is mostly invariant, yet during larval and adult stages, germ cells continuously multiply in a stem cell niche.

Early embryonic cell divisions happen quickly and don't have G1 or G2 phases. The G1 phase only appears late in embryogenesis in a small proportion of actively dividing cells, according to the existing evidence, and it is first noticed at gastrulation.

Different DNA replication rates, which are partly explained by the variable activation of the DNA-replication checkpoint, result in differences in the time of early embryonic cell cycles between lineages.

The formation of post-embryonic cell lineages is closely controlled, with cycles of cell division starting and ending at particular times during larval development. Although changes to the heterochronic pathway, which controls the sequence of larval programs, might indirectly change the time of cell divisions, the extrinsic or intrinsic cues that regulate the timing of initial cell-cycle entry remain unknown.

We can infer that the effect sugar has on the boiling time of water is that it  increases the boiling time of the water.

The boiling of a pure liquid such as water occurs at its boiling point.

The boiling point of a liquid is the temperature at which the liquid boil. The boiling point of pure water is 100°C.

When solutes are added to a solvent, it usually have the effect of raising the boiling point of the solvent. This is known as colligative properties of solutions.

For example, when sugar or salt is added to water, the boiling point and boiling time of water is elevated.

Hydrogen bonds between amide protons and carbonyl oxygens is necessary to stabilize a regular folding of protein secondary structure.

Amino acids are the building blocks of proteins, and each one has a specific role to play in the complex three-dimensional structure of these biomolecules. One of the key interactions that helps to stabilize protein structure is the hydrogen bond.

Hydrogen bonds between the amide protons and carbonyl oxygens are essential for proper folding of protein secondary structure. These weak bonds help to keep the protein backbone in place, and without them, the protein would simply collapse.

While other interactions, such as hydrophobic interactions, also play a role in protein stabilization, the hydrogen bond is essential for proper protein folding. Without it, proteins would simply be a jumble of amino acids, unable to perform their many vital functions in the cell.
