Most of the GMO crops grown today were developed to help farmers prevent crop loss. The three most common traits found in GMO crops are: (1) resistance to insect damage: (2) tolerance to herbicidesand (3) resistance to plant viruses. Let's consider #2 tolerance to herbicidesfarmers using herbicide-tolerant crops do not need to till the soilwhich they normally do to get rid of weedsWhich of these is NOT a positive environmental and economic impacts of this GMO trait ?
Answer:
: (2) tolerance to herbicides
Explanation:
Ability to the tolerate herbicides by some variety can lead to abuse of herbicides as over dose of it can be use in a particular region without considering the environmental hazard it can pose. Emission of some chemical compounds and release of some gasses from the herbicides result into land and air pollution especially when used in excess thing can affect the environment.
Residual impact on animals that feeds on such plant, it could lead to it death, after feeding if they move directly to the stream for feeding residual of such chemicals can be deposited in the water bodies leading to water pollution. Tolerance to herbicides is a good inventory but it can also be very detrimental especially when mid managed.

Scientists divide mitosis into four parts, or phases: prophase, metaphase, anaphase, and telophase.
True or false?
Answer:
true
Explanation:
[tex]\huge\boxed{True}[/tex]
_____________________________________MITOSISMitosis is a process where a single cell divides once into two identical daughter cells (cell division). The major purpose of mitosis is for growth and to replace worn out cells.
_____________________________________PARTS OF MITOSIS:It has 4 parts, Prophase, Metaphase, Anaphase, Telophase.
Prophase: The chromosomes condense into X-shaped structures that can be easily seen under a microscope.
Metaphase: The chromosomes line up neatly end-to-end along the centre of the cell.
Anaphase: The sister chromatids are then pulled apart by the spindle fibers. Each spindle fiber pulls one chromatid towards the opposite poles.
Telophase: At each pole of the cell a full set of chromosomes gather together. Membrane surrounds each pair forming a new cell

State two uses of fats to living organisms
Answer:
they act as messengers, helping proteins and do their job
The two uses of fats in living organisms are as follows:
They are actively involved in the storage of energy for metabolic functions. Fats generally insulate us and protect our vital organs.What are Fats?Fats may be characterized as a type of naturally occurring chemical substance that significantly describes a class of macronutrients utilized in metabolism called triglycerides.
Fat usually means any ester of fatty acids, or a mixture of such compounds, most commonly those that occur in living organisms. These groups of macronutrients are generally involved in the storage of energy for metabolic functions.
Triglycerides, cholesterol, and other essential fatty acids are the scientific term for fats the body can't make on its own in order to store energy, insulate us and protect our vital organs. They act as messengers, helping proteins do their jobs.

Hydrogen peroxide is a substance that is produced as a byproduct of many cell processes. However, hydrogen peroxide is toxic to cells. In fact, if cells are unable to break down hydrogen peroxide, they become poisoned and die.
The chemical reaction for the breakdown of hydrogen peroxide is shown below.
What role does catalase play in this reaction?
Answer:
In the reaction of decomposition of hydrogen peroxide (H₂O₂), catalase is the enzyme responsible for catalyzing this reaction.
Explanation:
Catalase is an oxide-reductase enzyme whose substrate is H₂O₂, a potentially harmful by-product of metabolism.
The reaction that is mediated by catalase is:
H₂O₂ ------catalase--- → 2H₂O + O₂
where catalase is the enzyme that breaks the bond of the additional oxygen in the molecule to obtain H₂O and free O₂.
People with catalase deficiency may experience disorders and diseases due to the accumulation of H₂O₂ in the body.

In this series of metabolic reaction, Compound R is converted into Compound A, and
Enzyme X then catalyzes the conversion of Compound A into Compounds B and D.
Compound B is converted to Compound C.
Assume that Compound Cinhibits Enzyme X and that Compound C is not consumed
in a subsequent reaction. As the concentration of Compound C increases, the rate of
production of which compound is LEAST likely to decrease?
A. Compound A
B. Compound B
C. Compound C
D. Compound D
Answer:
A. Compound A
Explanation:
Enzymes are specialized, folded proteins that act as biological catalysts- they speed up the rate of certain chemical reactions in biological systems. Enzymes bind to substrates like compound A to their active site, where they facilitate the modification of molecular strutures, creating new compounds.
Inhibitors like compound C can prevent enzyme-substrate binding activity; the chemical reactions do not occur because the substrates cannot gain access to the active site. Because enzymes show specificity, binding only to certain substrates, other molecules cannot be catalysed by the enzyme.
Here, the amount of Compound A, which is produced via the conversion of R, is increased due to the reaction inhibition- its conversion to B and D is not mediated by X, the inhibited enzyme. While conversion may still occur slowly, without its catalyst, more of the compound is being converted from R to A than A to B and D.
The concentration of A is least likely to decrease.

If you wanted to stay 20 feet below the surface of the water, what kind of buoyancy would you need to have? Positive, Negative or Neutral?
Answer:
It depends what kind of water.
Explanation:
Salt water:
You would need a negative buoyancy.
Fresh water:
You would need a neutral buoyancy.
Please let me know if I am wrong!
Buoyancy is the tendency of an object to float at the upper surface of the fluid due to upwards force. If the diver wants to stay below the water surface then they will need negative buoyancy.
What is buoyancy?Buoyancy has been defined by the upthrust experienced by an object in a fluid or liquid medium. It is a force that opposes or counters the weight of the object. Buoyancy can be positive, neutral, or negative. Positive buoyancy makes object float.
A negative buoyancy occurs when the object has more mass and density than the fluid so that the applied force makes them sink. So, if a person wants to stay 20 feet below the surface of the water then negative buoyancy has to take place.
Therefore, negative buoyancy will make a person stay at the bottom of the water.

What does it mean to have a hypotonic solution?
Answer:
A hypotonic solution has a lower concentration of solutes than another solution. In biology, a solution outside of a cell is called hypotonic if it has a lower concentration of solutes relative to the cytosol. Due to osmotic pressure, water diffuses into the cell, and the cell often appears turgid, or bloated.
Answer:
alright so there's 3 kinds of solutions!
hypotonic, isotonic and hypertonic
basically a cell is in a hypotonic
solution if the concentration of water
inside the cell is LOWER than the concentration
outside the cell. Water diffuses from high
to low. Water enters the cell.
and this is talking about ions!

Which describes sexual reproduction, and not asexual reproduction?
Answer:
One characteristic that describes sexual reproduction and that is not present in asexual reproduction is the combination of genetic information from two parents.
Explanation:
Sexual reproduction involves the participation of two individuals, whose genetic material is contributed and when they unite they give birth to a new individual, through the process of fertilization.
Individuals who reproduce sexually have the ability to form cells with half of their genetic charge, called gametes. The union of these cells forms the zygote, from which a new individual develops.
In asexual reproduction, a single individual is responsible for the reproductive process, which occurs by
Gemination. Bipartition Fragmentation. Parthenogenesis. Sporulation or sporogenesis.Each one of these processes represents a different type of reproduction than the one that occurs sexually.

In which situation is energy released by a plant?
when oxygen is released into the air
before energy is stored in sugar molecules
when plants break down sugar molecules
when sugar and oxygen are made
Answer:
When sugar and oxygen are made
Explanation:
Through photosynthesis certain energy’s convert solar energy into chemical energy. Photosynthesis is the process used by plants to harness energy from sunlight. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. The sugars are used by the cell as energy, and to build other kinds of molecules.
