Answer:
With millions of different kinds of organisms in the world, scientists must find order in all of this diversity. Scientists group living organisms into one or more of a few major categories as part discipline known as taxonomy. The bodies of organisms are organized into functional systems—cells are organized into tissues, and tissues are organized into organs. Body systems carry out critical functions, such as locomotion, reproduction, digestion, and circulation. All living things on Earth are composed of the same carbon-based, molecular building blocks.
Answer:
Wetland reduction has caused a decrease in the absorption zones for excess water. If the excess water cannot be absorbed by the soil, it increases the incidence and magnitude of flooding.
if I'm being honest I think it would be uhm C
Answer:
1) Break down of the nuclear membrane allowing mitotic spindles to connect to kinetochores:A. Metaphase
2)APC degrades securin which allows separase to become active which degrades the cohesin rings: E. Anaphase
3) Dephosphorylation of nuclear pore and lamins: F.Telophase
4) cleavage of plasma membrane by actin and myosin contractile ring:D.Cytokinesis
5) copying of the genome:C. Interphase
6) formation of the metaphase plate:B. Prometaphase
Explanation:
Answer:
The question lacks options, the options are:
A). the body cell has 2n; the sex cell has 1n.
B). the body cell has 26; the sex cell has two.
C). the body cell has 1n; the sex cell has 2n.
D). the body cell has 24; the sex cell has 26
The answer is A
Explanation:
According to the question, the snapping turtle possesses 52 chromosomes in its cell. This means that the chromosomal number of its body cell is 52. However, the turtle, which reproduces sexually will produce gametes or sex cells via meiosis. Meiosis is the kind of cell division that results in daughter cells (gametes) that have a reduced number of chromosomes (by half).
Based on this, the diploid cells (2n) of the turtle with chromosome number 52 will undergo meiotic division to produce haploid gametes or sex cells (n) with chromosome number 26.
N.B: Diploid (2n) means two complete sets of chromosomes while haploid (1n) means one complete set of chromosome.
The body cell of the turtle contains two set of chromosomes received from each parent, hence, making it Diploid (2n). However, meiosis will reduce the chromosome number to one set in each gamete i.e. haploid (n).
