Glycolysis is the first stage of cellular respiration and is an anaerobic process. During glycolysis, glucose is converted to two molecules of pyruvic
acid. How is glycolysis kept functioning during cellular respiration?

O
B. Two molecules of ATP from the cell are invested at the beginning of the process of glycolysis.
C. Pyruvic acid from glycolysis reacts to form acetyl-CoA, which then combines with a four-carbon compound in the Krebs cycle and re-enters
glycolysis.

Answer:
in the nucleus
Explanation:
Chromosomes are structures located inside the nucleus of animal and plant cells.
Answer: In the nucleus
Explanation:
Through the process of photosynthesis, plants make their own food using energy from the Sun, carbon dioxide from the air, and water from the ground. This food can then be stored for later use, or energy from the food can be released by the plant through the process of cellular respiration. This energy is then used to perform other life processes.

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

If you find a rock field with lots of conglomerate rocks, with lots of rounded rocks cemented together in big clusters, what can you say about the area you found?
it once was covered by magma
the area was once covered by a moving stream of water
the area was once shaken by earthquakes
Answer:
I think is B
Explanation:
The land around you, no matter where you live, is made of rock. If you live in a place that has good rich soil, the soil itself is finely broken down or weathered rock.
People that live in a desert region can easily find rocks on the surface. These rocks lay on a surface of clay that is also a product of weathering rock. Weathering is the process of breaking down rocks and minerals into smaller pieces by water, wind, and ice.
Sedimentary rocks are formed from the breaking apart of other rocks (igneous, metamorphic, or sedimentary rocks) and the cementation, compaction and recrystallization of these broken pieces of rock.
Sedimentary rocks are formed from broken pieces of rocks. These broken pieces of rock are called sediments. The word "Sedimentary" comes from the root word "Sediment".
Sedimentary rocks are usually formed in water. Streams and rivers carry sediments in their current. When the current slows around a bend or the river empties into a lake, or ocean, or another river the sediments fall out because of gravity. The larger sediments fall out first and the lightest sediments fall out last.

The thing that can be said about the area is B. the area was once covered by a moving stream of water.
Conglomerate rocks refer to sedimentary rocks that are made of sand and rounded pebbles which are held together by calcite, silica, or iron oxide.
Since there is a rock field with lots of conglomerate rocks, this could be a result of weathering. In such a case, the area may be once covered by a moving stream of water which could have led to the rocks that were formed.

How do you think the plant uses the sugars that it has created in photosynthesis?
The sugar produced by photosynthesis can be converted into the sugar glucose. Thousands of glucose molecules can be linked together to form the complex carbohydrate cellulose. Cellulose is a very tough molecule that is used to build the cell wall of plant cells.
pls mark brainliest if you feel like it...
The plant then releases oxygen into the air. Glucose, which is actually a sugar, feeds the plant. There are many uses of glucose in plants. Glucose helps plants grow, form flowers and develop fruit. It also helps plants develop seeds.

What would be the effect on the seasons and the northern and southern hemispheres if Earth were not tilted? Explain your answer.
(its science, not bio I'm in middle school 8th grade I don't know why it says highschool)
Answer:
If the Earth weren't tilted on its axis, there would be no seasons. And humanity would suffer. When a Mars-size object collided with Earth 4.5 billion years ago, it knocked off a chunk that would become the moon. It also tilted Earth sideways a bit, so that our planet now orbits the sun on a slant.
Explanation:
Up to what concentration is carbon dioxide a limiting factor for photosynthesis in low light intensity?
Answer:
Carbon Dioxide limits photosynthesis at a concentration of around 400 ppm (ambient concentration) in low light.
Explanation:
Limiting factors affect the photosynthetic rate, decreasing the potential amount of carbohydrate made via photosynthesis. Carbon dioxide is essential to this form of biosynthesis- it provides the inorganic carbon that is integrated into carbohydrate molecules.
Carbon dioxide is typically present in the atmosphere at concentrations of 0.04%. Light intensity typically cause stomata to open, and increase CO2 uptake. Higher concentrations of CO2 up to 0.1%, cause dramatic increases in the photosynthetic rate.
Low light, thus means less stomatal opening, and less CO2 uptake. As low light intensity can be limiting, it lowers the concentration of Carbon dioxide at which the rate becomes constant.

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.
