Plants in the desert would have a decreased number of stomata compared to rainforest plants. This is because desert plants need to reduce their water loss and keep out the hot and dry winds
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.
Answer:
The organisms that are the most reproductively fit.
All of them are structures found in different plants with the role in reproduction.
Flowers are found in flowering plants (angiosperms). Gametophyte (sexual phase within the life cycle of plants) develops inside the flower (e.g. ovules are located internally). Seeds are inside the protective shell.
The cones are the organs of plants, found in the conifers (Pinophyta), that contain the reproductive structures. The cones are woody structures and the seeds are naked in them.
Spores are also structures for the reproduction. The spores might be included in asexual reproduction: haploid and unicellular which develops into a new organism via mitosis, when the conditions are favorable. They can be part of the sexual reproduction in seed plants when they are included in the formation of more complex structures such as the seeds and pollen grains.
