Hope it Helps!! :D
The correct answer is C chromosome
Describe a trait.
A distinctive attribute or characteristic of a living thing is what is referred to as a trait. As a result, it alludes to particular traits or qualities that a living thing posses.Based on genetics, a live organism can be distinguished from others by the features that are fundamentally passed on from its parents to its offspring.Additionally, each species is distinct due to features that are controlled by deoxyribonucleic acid (DNA) through the arrangement of its alternating deoxyribose sugars.A trait is a particular quality that an organism possesses. Genes, the environment, or more frequently the relationships between them, can all influence traits. The term genotype refers to the genetic component of a trait.Numerous genes play a role in regulating cell division and development. This process is tightly regulated to guarantee that the DNA of a dividing cell is accurately duplicated, that any DNA errors are corrected, and that each daughter cell obtains a complete set of chromosomes. …Your traits, which are features or characteristics that you inherit from your parents, are determined by the information carried by your genes (say: traits). In the human body, each cell has between 25,000 and 35,000 genes.A gene is a segment of DNA located on a chromosome that codes for the production of a protein that regulates a certain attribute (or characteristic) of the organism. Let's say a plant progeny carries the gene for the trait known as "tallness."thus the correct response is C chromosomes

What type of solvent would dissolve a nonpolar solute
Answer:
Explanation:
For example, ionic compounds, which are very polar, are often soluble in the polar solvent water. Nonpolar substances are likely to dissolve in nonpolar solvents. For example, nonpolar molecular substances are likely to dissolve in hexane, a common nonpolar solvent.
Answer:
Explanation:
Like dissolves in like, so only non-polar solutes can dissolve in non-polar solvents.

Release of Energy - Student Guide
Assignment Summary
In this project, you will design, construct, test, and modify a device that releases thermal energy by
chemical processes. You will be provided specific materials by your instructor, and will use these
materials to design a device that releases energy to the environment. Next, you will build the device and
test it by gathering temperature data. Finally, you will use your data to evaluate the design and decide
how to improve your device.
Answer:

The device controlled the activation as shown by the water holding room temperature for 15 seconds until activation by crushing the pills. The temperature rose 30° over two minutes,showing a measurable exothermic reaction from the Calcium Chloride dissolving in the water.
Pour 5mL water in a quart bag
Place Thermometer in the bag to make contact
Fill two gelatin 000 capsules with 1 gram of Calcium Chloride
Place capsules into the bag
Wait 15 seconds to crush the capsules while they are submerged in the water

Using the Punnett square, we can determine the possibility of white-winged and yellow-winged offsprings.
Which phases of the cell cycle are included in interphase? Check all that apply.
G1 phase
S phase
G2 phase
mitosis
cell division
Answer:
Interphase is the longest stage of the cell cycle and can be divided into 3 phases: G1 phase, S phase, G2 phase. The newly formed cell matures during the G1 phase. If the cell is going to divide, it enters the S (synthesis) phase where the DNA is replicated and the G2 phase where more growth occurs.
The interface is the first phase of the cell cycle during which the cell grows to its adequate level to start the duplication of its genetic material, the phases included in interphase are:
G1 phase.The cell physically grows, duplicating its organelles and the proteins needed for subsequent stages.
S phase.A complete copy of the cell's DNA is synthesized, as well as a duplicate of the centrosome, which will help separate the DNA in later stages.
G2 phase.The cell grows even larger, generates new proteins and organelles, and prepares for mitosis, cell division.
Therefore, we can conclude that the interface comprises the G1-S-G2 stages, and during them it grows to its proper level to start the duplication of its genetic material.

Why would it be important to understand what controls the number and types of species in an ecosystem?
•THERE’S ALSO OTHER QUESTIONS IN THE PIC (if you could answer them it would be appreciated)
Answer:The short film Some Animals Are More Equal than Others: Trophic Cascades and Keystone Species opens by asking
two fundamental questions in ecology: “What determines how many species live in a given place? Or how large
can each population grow?” The film then describes the pioneering experiments by Robert Paine and James Estes,
in the 1960s and 1970s, which started to address them. Paine’s experiments on the coast of Washington state
showed that the starfish is a keystone species, having a disproportionately large impact on its ecosystem relative
to its abundance. Estes and colleague John Palmisano discovered that the kelp forests of the North Pacific are
indirectly regulated by sea otters, which feed on sea urchins that consume kelp. The presence or absence of sea
otters causes a cascade of direct and indirect effects down the food chain, which in turn affect the structure of
the ecosystem. These early experiments inspired countless others on keystone species and trophic cascades in
ecosystems throughout the world.

Increased sea surface temperature has the potential to kill vast areas of coral because of this phenomenon:
A.) invasive species
B.) coral bleaching
C.) ocean acidification
D.) oligotrophic
Answer:
B.) Coral Bleaching
Explanation:
Increased temperatures can cause coral to 'bleach' or lose their symbiotic zooxanthellae algae
Increased sea surface temperature has the potential to kill vast areas of coral because of the coral bleaching.
What do you mean by coral bleaching?Bleached coral Healthy coral Coral bleaching is the process when corals become white due to various stressors, such as changes in temperature, light, or nutrients.
When water is too warm, corals will expel the algae (zooxanthellae) living in their tissues causing the coral to turn completely white. This is called coral bleaching. When a coral bleaches, it is not dead.
Coral bleaching can be caused by a wide range of environmental stressors such as pollution, oil spills, increased sedimentation, extremes in sea temperatures, extremes in salinity, low oxygen, disease, and predation.

100 POINTS!!!!!!!!!!! ( I NEED FAST ANSWERS ) Why do we use uranium for nuclear energy?
Answer:
Uranium is the fuel most widely used by nuclear plants for nuclear fission. ... Nuclear power plants use a certain kind of uranium, referred to as U-235, for fuel because its atoms are easily split apart. Although uranium is about 100 times more common than silver, U-235 is relatively rare.
Explanation:
i looked it up
Answer:
In a nuclear reactor the uranium fuel is assembled in such a way that a controlled fission chain reaction can be achieved. The heat created by splitting the U-235 atoms is then used to make steam which spins a turbine to drive a generator, producing electricity.

Why does DNA replication occur before mitosis and cell division?
Answer:
Explanation:
DNA replication needs to occur because existing cells divide to make new cells, so that the DNA needs to be copied before cell division so that each new cell receives a full set of instructions.
DNA replication - It is the process of producing two identical copies of DNA molecules from one original DNA molecule.
The cell cycle is the series of events that lead to a cell's genome duplication and final division into two daughter cells.
It consist of two main phases - Interphase and M phase
DNA replication occurs at the interphase during S phase of the cell cycle.
Mitosis begins after interphase.
DNA replication occurs before mitosis and cell division so that each newly formed daughter cell receive full set of chromosomes as of parent cell in their nucleus. DNA contains instructions that helps the newly formed cells to operate properly.
