The answer is saturated fats.
Solids fat are solid at a room temperature. They contain a high proportion of saturated fats and that is the reason they are solid. Saturated fats are fat molecules without double bonds between carbon molecules and are saturated with hydrogen molecules. Hydrocarbon chains of saturated fats are straight and pack closely, forming a solid structure.
Answer:
Deforestation, which is logging or burning forests, is a way in which humans cause erosion. Removal of the vegetation covering the ground causes the soil, which is unprotected against wind and water, to erode. The loss of topsoil essentially destroys the ability for the land to regenerate.

Answer:
The theory of evolution by natural selection
Explanation:
Nowadays, it is widely accepted that chimpanzees are primates closest related to us. Darwin's postulated "The theory of evolution by natural selection", in the book "On the Origin of Species" in 1859. It is a theory that explains how species evolve over successive generations by gradual changes and the selection of the most adaptive phenotypes. Anatomical, fossil, and genetic evidence support the idea of an evolutionary link as Darwin predicted between hominids (humans) and other primates.
In regard to genetic evidence, whole-genome sequence analyses have shown that humans and chimpanzees share about 98% of sequence homology. Moreover, according to the phylogenetic tree, both species evolved from one common ancestor that was present approximately 4 million years ago.
In regard to anatomical and fossil evidence, it has been discovered that the chimp brain has a similar size to human extinct relatives, and thereby also supporting an evolutionary link between both species.
Answer: When two homologous chromosomes transfer genetic information in prophase 1.
Explanation:
Meiosis is a process in which the a single parent (diploid) cell divides twice to produce four haploid daughter cells which have half the number of chromosomes as that of their parents.
Crossing over can be defined as exchange of genetic material that occurs between the chromosomes of opposite germ line. This process helps in transfer of mixing of traits to the offspring from both parents. This occurs in prophase 1 stage of meiosis. This process is the basis of formation of gametes or sex cells that are eggs in female and sperm cells in the male. The paired homologous chromosomes from single parent align to form a bivalent so that cross over each other and a unique combination of trait develop after this process.
Answer:
amygdala
Explanation:
Based on the information provided within the question it can be said that the part of the brain most likely damaged would be the amygdala. This is the part of the brain that is responsible for emotions, survival instincts, and memory. Therefore if you are not afraid of certain situations, animals, or events it is because your survival instincts for those situations are not working properly, therefore there is something wrong with the amygdala.
