Explanation:
Answer:
Of the 23 pairs of chromosomes in any normal human cell, the first 22 pairs provide directions for an individual's body and brain development. Scientists now estimate that about half of a person's personality traits and cognitive abilities can be traced to genetic influence and that psychological disorders arise from the interactions of many genes.
Explanation:
Chromosomes are small molecules that have the ability to carry all the genetic information needed to form a living being. These chromosomes are donated by an individual's parents and are used to form 23 pairs that determine all the internal and external characteristics of an organism. Among these 23 pairs, one pair will be responsible for determining the individual's gender, and the other 22 pairs will be responsible for the instructions that will make up the entire body and brain of the individual. Many scientists believe that chromosomes are responsible for even a part of a person's personality traits and that the genes they carry are directly related to the existence of psychological disorders.
C coz asexual means no mixing gametes between male and female parents. Child and parent is GENETICALLY IDENTICAL. can be found in plants. Examples include rhizome and bulbs.
Sexual reproduction involves both sex and two (haploid) gametes produce one (diploid) zygote
Inbreeding reduce genetic diversity coz parents of similar gene sequence produce offspring. Never lead to genetically identical offsprings because of crossing over of non-sister chromatids in meiosis I, random assortment of chromosomes in meiosis I, random fusion of sperms and eggs during fertilisation and mutations.
Selective breeding does not interfere directly with gene contents, only select individuals with preferable traits for reproduction to increase the chance of producing offsprings with said traits. Other traits of parent and offspring could be different.
Answer:D. tapeworms live inside a goats body in a close relationship the goat.
Explanation:
In parasitic relationships,the parasite lives on the host and benefits from the host while causing harm to the host .the host does not benefit.the parasites are usually in close relationship with their host as their food source are substances of the host organisms.
The parasite may live in the host , these are called Endo-parasites.
The parasite may live outside the host, these are called ecto-parasite. In this example, the tapeworm is an endo-parasite that lives in the digestive tract of the goat. It absorbs digested food in the intestine through it's body surface.
In predator and prey relationship, the predator usually has to hunt for the prey and feed on it. It may kill it first or may not
