Answer:
Plants, animals, wind
Explanation:
I used the process of elimination. Heat and sediment cannot move dirt and/or rocks
Animal and plant movement is a factor in biological weathering. For instance, a plant may grow in a gap in a rock and, as its roots spread, cause the crack to widen. Even you have the potential to weather! Thus, option C is correct.
What loosen and carry away rock during erosion process?The dirt is kept in place by plants. Some animals scrape pebbles as they eat to weather them. Other creatures alter the surface of the Earth by digging into it and shifting stuff.
The majority of the vegetation can be destroyed by an excessive number of animals, which speeds up erosion.
Earthen materials are worn away during erosion, a geological process in which they are moved by wind or water.
Therefore, Earthen materials are worn away during erosion, a geological process in which they are moved by wind or water.

What is nutrient cycling?Nutrient cycling is the process by which nutrients are transformed, transported, and exchanged between different parts of an ecosystem. Nutrients are essential for the growth and survival of all living organisms, and they are constantly being recycled through various processes in the environment.
For example, plants absorb nutrients from the soil and water, and then animals consume these plants and incorporate the nutrients into their own bodies. When animals die, their bodies decompose, releasing the nutrients back into the soil or water, where they can be taken up by plants again. This continuous flow of nutrients between living organisms and the environment is known as nutrient cycling.
Nutrient cycling is important because it helps to maintain the balance of nutrients in an ecosystem and supports the functioning of the ecosystem as a whole. It is influenced by many factors, including geological processes, weather patterns, and the actions of living organisms.

The lock-and-key mechanism refers to a) the complementary shapes of an enzyme and a substrate. b) the attractive forces between an enzyme and a substrate. c) the ability of an enzyme to lower the activation energy of a reaction. d) the ability of an enzyme to “unlock” the products of a reaction.
Answer:
A. The complementary shapes of an enzyme and a substrate
Explanation:
The Lock-and-Key model was made to show how an enzyme's active zone fits a substrate and how they bond together. It correlates just like a lock and a key; you have to have the correct-shaped key in order to open a lock. Same process of thought with the enzymes; you must have the same shape for both in order to bind together,

A cell has a defect in its receptor for growth factors, preventing growth factors from attaching to and signalling the cell. Based on this, which prediction below is most likely?
A. The cell will remain dormant in GO phase.
B. The cell will grow uncontrollably and continue to divide as long as it has food.
C. The cell will replicate its DNA but be unable to begin mitosis.
D. The cell will begin DNA replication but will be unable to complete S phase.
Answer:
Option B
Explanation:
B. The cell will grow uncontrollably and continue to divide as long as it has food.
Cell growth is theeoretically stimulated by the binding of growth factors to their receptors using signaling pathways.
These pathways are regulated by proteins which are encoded for in the genes.
The gene that controls the regulation of these pathway when mutated produce malfunctioning signaling protein thus not allow for regulations of the cell cycle causing uncontrollable cell division. These mutated genes are called oncogenes.
explain why all the offspring in the F1 generation were yellow instead of half being yellow and half green, or some other mix of the colors. Hint: Remember that Mendel coined the terms dominant and recessive.
Answer:
Yellow is a dominant trait.
Explanation:
There are dominant alleles and recessive ones. Say Y is a dominant allele and y is a recessive one. YY makes yellow, Yy makes yellow, and yy makes green. It takes just one dominant allele to make a phenotype (physical traits) express it. Look at the photo to help guide you. Using a punnet square you can find that both parents give a dominant allele and it only takes one.

After duplication, at what point does a cell become two cells with identical DNA? starting in prophase end of anaphase end of cytokinesis
Answer:
The correct answer is - end of cytokinesis.
Explanation:
Cytokinesis :- a procedure that partitions the cytoplasm and plasma layer of a cell, bringing about two indistinguishable cells that contain their own DNA, nucleus, nuclear membrane, and plasma membrane.
During the last phase of the cell cycle, cytokinesis permits the cell to complete the process of isolating, making two cells with indistinguishable duplicates of DNA
The cell squeezes in the equator area with the assistance of a ring of contractile protein filaments. The formed cleavage furrow develops until the two cells squeeze off totally.
Thus, the correct answer is - end of cytokinesis.
Answer:
end of cytokinesis

Which of the following would you use to inhibit the contraction of muscle in vitro as a control for an experiment you are conducting?
A. a motor protein ATPase inhibitor
B. a drug that increases T-tubule depolarization
C. a drug that increases sarcoplasm Ca2+ concentration
D. a Ca2+-ATPase inhibitor
E. All would inhibit muscle contraction.
Answer:
The correct answer is option A. a motor protein ATPase inhibitor.
Explanation:
Motor proteins are sub-atomic motors that utilize ATP hydrolysis to move along cytoskeletal filaments inside the cell. They satisfy numerous capacities inside the biological system, controlling the sliding of filaments for muscle contraction and intervening intracellular movement along biopolymer filament tracks.
The two globular head motor areas in heavy chains can change over the chemical energy of ATP hydrolysis into mechanical work to move along microtubules.
Thus, in vitro experiment inhibitor of the motor protein, ATPase will be a control.

Among 1,000 gametes produced by a plant of genotype o ci +/+ + p, what types of gametes would be expected, and what number would be expected of each? Assume that the chromosome interference across this region is 80%.
Answer:
Expected gametes : o+ ci+ p+,o- ci- pi-, o+ci- pi+,o- ci+ pi-, o+ci+ pi-, o- ci- pi+
Explanation:
Genetic distance between genes is equal to the recombination frequency, so the total number of recombinant gametes can find out by multiplying the recombination frequency of both sides to the total number of gametes.
Interference= .80;
Coefficient of incidence
= 1 - 0.80
= 0.20
15cM = 15% recombination,
20cM = 20% recombination.
Then, Number of recombinant offspring

Explanation:
Consider that it takes, on average, 24 hours (or 1,440 minutes) for each onion root tip cell to complete the cell cycle. You can calculate the amount of time spent in each phase of the cell cycle form the percentage of cells in that stage.
Percentage of cells in stage X 1,440 minutes = ________ minutes of cell cycle spent in stage.
Answer: Hope this helps you :)
To calculate the time spent on each stage of the cell cycle, we need to know the total time required to complete the cycle and the percentage of cells that are in that stage. Then, take the product of both values.
--------------------
According to the statement,
The percentage of cells in a stage X 1,440 minutes = Time in minutes of cell cycle spent in the stage.
So, to know how much time is spent in each stage of the cell cycle, we need to know the time it takes for a cell to complete the whole cell cycle, and how many cells there are.
We already know that it takes, on average, 24 hours (or 1,440 minutes) for each onion root tip cell to complete the cell cycle.
Now, we should count the number of cells. Since I do not have a slide, I will assume that there are at least 50 cells, and from that 50 cells present in the slide, 25 are in the same stage. Let us say that the 25 cells are in the prophase.
So, considering a total number of 50 cells (100%), 25 cells equals 50% of the total.
Now, we know that
Time required to complete the cell cycle = 1440 minutesPercentage of cells in the prophase = 50%
Minutes spent in prophase = % of cells in prophase x 1440 minutes
Minutes spent in prophase = 50% x 1440 minutes
Minutes spent in prophase = 0.5 x 1440 minutes
Minutes spent in prophase = 720 minutes
According to this example, cells spend 720 minutes of their time in the prophase.
Now, I suggest you count how many cells do you have in your slide, and recognize how many are in each of the stages. Then you will be able to calculate the real-time spent per stage.

What kind(s) of cells can develop from totipotent stem cells?
O A. Only cells that are identical to the original stem cell
B. Only cells that are closely related to the original stem cell
C. Any cells of the human body, but not cells of the placenta
D. Any cells of the human body or the placenta
Answer:
D.
Explanation:
Totipotent cells can make any of the 220 cell types in an embryo, as well as the cells found in a placenta!
Any cells of the human body or the placenta can develop from totipotent stem cells. Therefore, the correct option is D.
Totipotent stem cells have the unusual ability to differentiate into any type of human body cell, including placental cells. They have the ability to generate all types of cells, including endoderm, mesoderm, and ectoderm, the three basic germ layers. Because of their potential for development, totipotent stem cells can produce both extra-embryonic and embryonic tissues. Although cells produced from totipotent stem cells can differentiate into any cell type, due to maturation and specialization processes, they are not always identical to the original stem cell.
Therefore, the correct option is D.

In which biome would you be most likely to find plants and animals that are
adapted to survive in extremely cold temperatures?
A. Desert
B. Savanna
C. Rain forest
D. Tundra
The correct answer is D. Tundra
Explanation:
Tundra biome is one of the coldest biomes on Earth, indeed, the temperature in this biome can be as low -50° C in some zone. At this extremely cold temperature, animals and plants have adaptations to survive in these climatic conditions. For example, animals such as the arctic hare or the polar bear that are found mainly in the tundra biome have thick fur that helps them keep body temperature despite low temperatures in their environment. Thus, the biome in which you would most likely find species adapted to extremely cold temperatures is the Tundra.
