The function of lysosomes will not be carried further because the formation of lysosomes will not be carried successfully when there is a mutation in the gene responsible for the formation of vesicles at the trans end of the Golgi apparatus.

A Mutation may be defined as the sudden, stable, and inheritable change in the genetic material of an organism. The organism which undergoes the process of mutation is known as a mutant. The agent of mutation is known as a mutagen.

The origination of the lysosomes will be stimulated by the trans end of the Golgi apparatus in the form of vesicles. And when there is mutation occurred in the gene it is responsible for the formation of these vesicles. Its function of it must be eliminated.

Therefore, as a result of a mutation in the gene leads to the deformation of lysosomes.

The octet rule stablishes that to form molecules, the atoms composing them must share electrons in their outer layer to complete the octet and reach a stable electronic configuration. Image in the attached files.

The octet rule is a theory stated by Lewis (1917) and is used to explain how atoms are combined.

The theory explains how atoms from different elements tend to complete their outer energy layer with 8 electrons to reach a stable electronic configuration.

The ions of different chemical elements complete their last energy levels when combined with other atoms.

Atoms can either gain or share electrons with other atoms to compose the molecule,

In this way, the rule explains how atoms form bonds to create a molecule.

Meta-analysis is the name for the quantitative analysis of a large collection of scientific results that attempts to make sense of a diverse selection of data.

Meta-analysis:

A meta-analysis is a statistical study that incorporates the findings of several scientific investigations. When there are several scientific studies addressing the same subject, meta-analyses can be undertaken, with each individual study presenting measures that are predicted to have some degree of inaccuracy. The goal is then to utilise statistical methodologies to produce a pooled estimate that is closest to the unknown common reality based on how this inaccuracy is viewed. The evidence-based medical literature regards meta-analytic results as the most reliable source of evidence.

plants make their own food with the help of sunlight. However not all parts of a plant structure are suitable to do this, so not all types of plant cells contain chloroplasts.

Both biotic and abiotic elements are present in the cycles of nitrogen, phosphorus, water, and carbon in pond ecosystem.

An ecosystem in ecology is made up of biotic and abiotic elements. The living components of a pond ecosystem, such as plants, animals, and microorganisms, are known as biotic factors. Abiotic factors are the nonliving elements of the environment, such as the air, minerals, temperature, and sunlight. Both biotic and abiotic elements are necessary for organisms to live. Additionally, a lack or surplus of either component might restrict the effects of other variables and affect an organism's survival.

A mineral has no particular planes of weakness in its lattice structure, so it does not break along particular planes. Fracture is what happens when this mineral is struck.

An organized collection of points that characterizes a crystal-forming particle's structure is known as a lattice structure. The lattice points help identify a crystal's unit cell. In the sketched structure, every particle (yellow) is the same.

The face-centered cubic (FCC), body-centered cubic (BCC), and hexagonal closest packed are significant lattice structures.

Because of the structural positions of atoms and ions in the crystal, cleavage is the tendency of minerals to split along crystallographic planes, resulting in planes of relative weakness.

While a break occurs when the rock shows no evidence of a plane of weakness. In the event that the break is clean, parallel, and has reflective surfaces, it can be distinguished from a fracture.

Facilitated diffusion is the process where a solute bind to a carrier in the plasma membrane that then changes shape and releases the solute to the other side of the membrane.

In carrier-mediated diffusion, Polar molecules including simple sugars, simple carbohydrates, and amino acids are transported across the membrane by carrier-mediated diffusion, the carrier protein, which actually alters form in the process, is responsible for this.

There are three mechanisms of carrier-mediated transport;

1. Facilitated diffusion: Solutes diffuse across transport proteins in the plasma membrane when their diffusion is facilitated. A form of passive transport is facilitated diffusion. Because the solution is flowing down the concentration gradient, passive transport is still occurring despite the presence of transport proteins in assisted diffusion.

2. Primary active transport: Primary active transport, also known as direct active transport, employs chemical energy (such as that from the cell membrane's adenosine triphosphate or ATP) to move all types of solutes against their concentration gradient across a membrane.

3. Secondary active transport-It is known as secondary active transport when a solute is transported in the direction of its rising electrochemical potential while a second solute, typically an ion, is spread out more readily in the direction that its electrochemical potential is lowering.

According to Sedlak, there are factors that contribute to water shortages.

One is the population .

Two is the climate change.

A drought is a period of time when an area or region experiences below-normal precipitation.

The amount of precipitation at a particular location varies from year to year, but over a period of years the average amount is fairly constant.

These are two major changes that have occurred over the past couple of years.

Sedlak gave reasons for water shortages which is that the population has clearly increased dramatically, which means more people need access to water to survive.

The second impact is the climate change.

Climate changes can cause drought which in effect means no water coming in to replace any previous ones.

The true breeding strain that will be easier to produce will be: true-breeding peas with a trait caused by a recessive allele.  

A true-breeding strain is the one that is produced after continuous self-pollinations for several generations. True-breeding strain does not alter the traits when passed from the parents to the offspring. Both the alleles of the gene are the same when true-breeding.

Recessive allele is the one that cannot show its effect when present along with the dominant type of allele. It is easier to produce a true-breeding strain of recessive alleles because these can show their effect only when present in homozygous condition. Dominant allele on the other can show its effect even in heterozygous condition and hence it becomes difficult to determine if the trait is true-breeding or not.
