Answer: Response to the environment.
Explanation:
Living organisms respond to their environment, and this <u>response to stimuli is an important characteristic of life, because it helps the organism to stay in balance</u>. Anything that causes a living organism to react is called a stimulus, which can be external or internal.
The effectors produce an appropriate response to the stimulus in order to maintain homeostasis within the organism.
Ultraviolet light can damage the DNA in cells, causing mutations. So, once the skin is exposed to sunlight, the organism tries to cover all the cells with melanin, which block UV rays.
Answer:
C. Is a repeated sequence of DNA in a non- coding sequence
D. Can be composed of a variable number of repeats in different people
Explanation:
Short Tandem Repeats (STRs) are short DNA motifs, i.e., short nucleotide repeat units (generally 2-7 base pairs in size) that may have a different number of repeats among individuals (alleles). Polymorphic STR sequences are very useful genetic markers and therefore they are used for different purposes, e.g., for constructing genome linkage maps, identification of individuals and/or populations, paternity testing, etc. For example, in the USA, the Combined DNA Index System (CODIS) is a databank that stores different DNA profiles based on 13 core STR <em>loci</em> which are used in forensic identity testing.
the thylakoid will have fewer hydrogen ions
Parasitism.
There are several types of biotic relationships that is occurring
every single moment in the ecosystem and one is parasitism. In this scenario
with human beings and mosquitos, this phenomenon of interaction is
distinguished as parasitism where mosquitos draws blood that contains nutrients
from the human tissue to use it as its source of food and then leaves harmful
substances and bacteria in the human’s blood stream.
