____ organized on chromosomes carry the information that controls the functions of the cell.
Genes organized on chromosomes carry the information that controls the functions of the cell. Each gene contains a particular set of code for a particular molecule or protein for a specific function.
Population genetics is the study of the variation in genes among a group of individuals. True False
Plants have cell walls to give them more structural strength. in order to facilitate movement of molecules from one plant cell to another, there are channels called ___________________ that run through the cell walls
Final answer:
Plasmodesmata are microscopic channels that facilitate the transport and communication between plant cells by connecting their cytoplasm, enabling the movement of water, nutrients, and other molecules throughout the plant.
Explanation:
The channels that run through plant cell walls facilitating the movement of molecules from one plant cell to another are called plasmodesmata. These are microscopic passages that allow plant cells to transport and communicate by directly connecting their cytoplasm.
Plasmodesmata enable the transfer of water, nutrients, and signaling molecules, bypassing the barrier that plant cell walls present to cell-to-cell contact. Along with vascular tissues like xylem and phloem, plasmodesmata play a crucial role in distributing resources throughout the plant.

The sugar __________ is found only in milk and milk products.
if a cell is isotonic in an 80% sucrose solution, how will the movement of water across the cell membrane affect the size of a cell if it is moved from an 80% sucrose solution to a 40% sucrose solution
The answer is; The cell will increase in size
When the cell is moved is the 40% sucrose solution, the solution will be hypotonic to the cytoplasm of the cell. Therefore, through osmosis, water will move from the sucrose solution to the inside of the cell. In osmosis, water moves from a hypotonic solution to a hypertonic solution through a semi-permeable membrane. If the cell is an animal cell, it may lyse because it has no cell wall to give it structural support.
what is the range for the following set of measurements? 27c, 12c, 31c, 19c, 23c, 11c, 17c
A) 0c to 100c
B)11c to 31c
C)1c
D)27c to 17c
Answer: B) 11c to 31c
Explanation:
We know that the range of any data gives us a interval which contains all the data and provides an indication of statistical dispersion from minimum value to the maximum value.
The given set of measurements : - 27c, 12c, 31c, 19c, 23c, 11c, 17c
Here the highest measurement :- 31c
The least measurement :- 11c
Then , the range of the given set will be :-
11c to 31c
Hence, the range for the given set of measurements is 11c to 31c .

How have the Earth systems and life co-evolved over time?
Through evolution. The mechanism by which organism adapt and be able to survive in an environment however limited is because of evolution. Primitive life is different from the current ones because the early Earth was different from the ones that exists today. Further, as life thrived, Earth was able to supply the necessary materials for life to survive and continuous be complex as it is today.
Which term is associated with asexual rather than sexual reproduction?
A) zygote
B) conjugation
C) binary fission
D) alternation of generations
Answer: C. Binary fission
There are two modes of reproduction used by the living organisms to reproduce offspring. The asexual mode of reproduction is a process in which the organism does not require the gamete formation, and does not require a mate for copulation, only a single parent is involved in this process. The offspring produce are genetically identical to their parent. But sexual reproduction gamete formation is necessary, and a mate is required for copulation. The offspring are not genetically identical to their parents.
Binary fission is a term that is associated with asexual rather than sexual reproduction. Binary fission is a type of asexual reproduction, in this a fully mature parent cell divides into two daughter cells. In this process segregation of the genetic material and it's replication takes place simultaneously. The genetic material is equally distributed to both of the daughter cells. Binary fission can be observed in some prokaryotes such as bacteria. It is also seen in single celled eukaryotes such as Amoeba and Paramecium.
