Explanation:

In thermoplastics, the arrangement of monomeric units is linear and in thermosetting plastics, it is cross-linked. Thermoplastics are usually soft, weak and less brittle, so can get soften on heating and stiffen on cooling. They can be melted, remoulded and recycled easily.

Frictional force refers to the force generated by two surfaces that contacts and slide against each other, If an object is pushed against the surface, then the frictional force will be increased and becomes more than the weight of the object

Organisms in the rainforest compete for biotic and abiotic factor by using resources that are available in the surrounding environment.

Competition occurs when the resources are available in scarce or limited amount. When there is an abundant amount of resources, there is no competition between organisms. The organism which is stronger than other organism can use more resources i.e. water, food and space etc and increase its population.

Those organisms which feed on similar food and other resources can compete with each other and the stronger organism will use the resources in large amount.

Answer:

Epistasis

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants

In Genetics, a gene pair has the ability to influence other gene pairs based on their combined activities which produces some effect on phenotype; this is called epistasis.

Answer:

50%

Explanation:

An inversion is a genetic phenomenon that occurs when a chromosome breaks into two genomic sites, thereby the resulting DNA fragment is reversed and subsequently inserted into the same chromosome location. A pericentric inversion occurs when the chromosome breaks are located on opposite arms or sides of the chromosomal centromere. Moreover, crossing over (or recombination) is the exchange of genetic material between non-sister chromatids during gamete production. An inversion carrier, as in this case the woman who is heterozygous for a pericentric inversion, can produce four types of gametes. If there is no crossing over, half the chromatids will produce normal gametes (without the recombination event) and half the chromatids will produce balanced gametes that will transmit the pericentric inverted chromosome. On the other hand, if there is crossing over, half the chromatids will have one duplication on the first chromosome arm together with a deletion on the second chromosome arm, and the remaining half of the chromatids will have an inverse arrangement.

Answer:

Between depths of tectonic plate boundaries and the outer core.

Explanation:

The rate of temperature increases below the Earth's surface is greatest between depths of tectonic plate boundaries and the outer core.  At the depth, some of the heat comes from the Earth's core while most of the heat comes from decay of radioactive elements, mainly uranium, thorium and potassium that is located in rocks of the crust. So we can say that the the increase in temperature with depth varies with the chemical composition and age of the rocks.

Explanation:

Cancer is the common name for a group of diseases in which there is a division of the body's cells, whose growth exceeds that of normal tissues and which persists in the same excessive manner. It can begin in a localized manner and spread to other surrounding tissues and its malignancy is very variable, according to the aggressiveness of its cells and other biological characteristics of each type of tumor. In general, the behavior of cancer cells is characterized by lacking the reproductive control required by their original function, acquiring the capacity to invade tissues (metastasis), spreading through the organism via the lymphatic or circulatory system, and causing the growth of new tumors in other parts of the body.

A gene is a hereditary unit composed of DNA that carries the instructions for producing proteins, which do much of the work in our cells. Certain genetic alterations can cause cells to evade growth controls and become cancerous cells. These changes can be inherited from our parents if the changes are present in the germ cells (eggs and sperm) and they are called germline changes. In addition, cancer-causing genetic changes can also be acquired during a person's lifetime (somatic or acquired changes), as a result of DNA errors that occur when cells divide either spontaneously or by exposure to carcinogenic substances that damage DNA (environmental factors), such as certain chemicals in tobacco smoke, or radiation, such as ultraviolet rays from the sun. These substances damage DNA, acting as mutagens.

Sometimes, the changes are not in the DNA sequence. For example, the epigenetic modifications are the presence of chemical marks in DNA which can determine if the gene is expressed. This means, whether and how much messenger RNA is produced, because the messenger RNA is translated into proteins.

So, cancer cells have genetic changes compared to normal cells. These changes are due to mutations that can be inherited, acquired spontaneously during life, or acquired due to environmental factors such as sun exposure, smoking, and other factors. In addition, the fact that a person has the cancer-related mutation does not necessarily mean that he or she will develop the disease during his or her lifetime. In some cases, even if they have this genetic vulnerability, they remain healthy, because cancer is a multifactorial disease that depends on many factors, such as the immune system, nutrition and certainly many others currently unknown to medicine.

Answer:

Maize is monocot and fibrous roots whereas mustard is dicot and tap roots system.

Explanation:

The main difference between maize plant and mustard plants is that Maize is a monocot plant means only one cotyledon in their seed whereas Mustard are dicot which means having two cotyledons. Maize plant has a fibrous root system whereas mustard plant has tap root system. The leaves pf maize plant have parallel venation while on the other hand, the leaves of mustard having reticulate venation. The seeds of maize is bigger in size as compared mustard seed.
