Which of the following is the term used when pollen from GMO crops fertilizes non-GMO plants?

O gene splicing
O genetic drift
O crossbreeding
O outcrossing

Answers

The term used when pollen from GMO crops fertilizes non-GMO plants is: (c) crossbreeding.

GMO crops are the genetically modified crops. These are those plants that get their genetic sequence modified using various techniques so as to bring out the best characteristics and yield from the plant. The modification can be in the form of addition, deletion or exchange of genes. Various crops that have been modified are: soybean, cotton, potato, etc.

Cross-breeding is the mating between two organisms that may be of different species, breed or variety. Since GMO crops and non-GMO crops do not belong to the same variety, they can have cross-breeding between them.

An increase in the membrane permeability for a solute will result in an increase in the driving force for diffusion of that solute through the membrane. This statement is TRUE.

Surface area and porosity/permeability are the two variables that are most relevant to diffusion via a membrane. Slower diffusion will result from a membrane with less permeability or less surface area, which will obstruct molecule motion. More permeable cells can withstand cold and freezing more easily, but they could also become dehydrated.

In humans, mitochondrial genetic disorders are inherited from only the mother. The severity of such diseases can vary greatly, even within a single family. What form of inheritance does this represent?.

Answers

The form of inheritance represented by mitochondrial genetic disorders is cytoplasmic inheritance.

The cell contains several cell organelles like mitochondria, chloroplast, Golgi apparatus, endoplasmic reticulum, etc.

Among the organelles present inside the cell, mitochondria and chloroplast are the two organelles that contain their own DNA.

During fertilization, the fusion of sperm and the ovum takes place to form the zygote.

The majority of the cytoplasm present inside the zygote is from the maternal cytoplasm i.e., the ovum. The paternal contribution to the zygote’s cytoplasm is negligible.

Therefore, if any disorder occurs in the maternal mitochondrial DNA, it will get inherited by the offspring.

As the mitochondria are present in the cytoplasm of the cell, the inheritance of mitochondrial traits is known as cytoplasmic inheritance.

What is Density patterns?

A solid form that is less dense than its liquid form, a comparatively high boiling point of 100 °C for its molar mass, and a high heat capacity, are all brought about by its hydrogen bonding.

The density equation is straightforward: Take the mass of an item with uniformly distributed material.

A substance's density is a measurement of how heavy it is in relation to its size. When placed in water, an object will float if its density is lower than that of the water, whereas it will sink if its density is higher. The density of a material is a distinguishing quality that is independent of the substance's volume.

Water has excellent cohesion power.

Hydrogen bonds lead water molecules to exhibit intense intermolecular attraction. We refer to this as cohesiveness.

The specific heat of water is high.

These two characteristics result from the need for additional energy to break hydrogen bonds. The term "specific heat" refers to the amount of heat that 1 g of a substance must absorb or lose to change its temperature by 1°C. Water has a high specific heat (1 calorie/g/°C). This characteristic guarantees gradual water heating and maintains the environment's and living things' stable temperatures.

When water freezes, its density decreases:

At 4°C, water has its highest density. On the other hand, ice is less dense than liquid water and floats on surface water, insulating the underwater film freezing and protecting aquatic life. However, at 4°C, water becomes less dense due to their separation.

The dielectric constant of water is high.

This fights against the attraction of ions with opposing charges. As a result, water is an effective solvent for many non-ionizable organic compounds and salts.
