Explanation:
Cell division is the process where cells divide to form 2 identical daughter cells. This is important in the growth of an organism to a larger size, in the replacement of old cells, and in the healing of wounds such as cuts on the skin.
Cell division occurs in both prokaryotes and eukaryotes. Prokaryotic cell division occurs by binary fission, whereas eukaryotic cell division is more complex.
If cell division in eukaryotes such as humans occurs in a deregulated manner (i.e. checkpoints are ignored) it can lead to uncontrolled proliferation, which is one of the primary ways in which cancer can develop.
Eukaryotic DNA is organized into chromosomes. After cell division, they form sister chromatids that are ready to be divided into daughter cells. Option 8 should be nucleosomes (part of how the DNA is organized), but this is not an option in your worksheet. Also, number 5 is missing, which I think likely comes after number 4 (prokaryotes) and refers to the fact that prokaryotes only have a single chromosome).
Cell division in eukaryotes occurs through the cell cycle. Which has two phases: interphase and mitosis. The cell will spend most of its life in interphase, where it is waiting for the signals to divide, and then preparing to divide.
Interphase can be divided into G1 phase, S phase, and G2 phase. G1 is the first "gap" phase, where the cell is making preparations before it can divide, such as ensuring conditions are favorable for cell division. Then the DNA is synthesised in the S phase, i.e., this is where DNA replication takes place. G2 phase is the final stage before the mitosis phase, where the cell checks the DNA has been correctly replicated before proceeding to mitosis.
Mitosis is the process where the cell divides the chromosomes into two identical daughter cells and divides. The 4 phases are prophase, metaphase, anaphase and telophase. These phases are followed by cytokinesis, which is where the cell cytoplasm physically splits to produce the two daughter cells.

Describe the function of the RESPIRATORY SYSTEM and the function of the CIRCULATORY SYSTEM in your own words
Answer: circulatory is when ur blood circulates and respiratory is the system we use to breath if I remember correctly
Explanation:
The respiratory system enables gas exchange, drawing in oxygen and expelling carbon dioxide. The circulatory system transports oxygen-rich blood to the body's cells and returns oxygen-poor blood to the lungs. Together, they maintain essential bodily functions.
The respiratory system plays a crucial role in the exchange of gases between the body and the outside air, a process known as respiration. This involves two main steps: drawing oxygen into the lungs and releasing carbon dioxide from the body. The oxygen absorbed in the lungs is then transferred to the blood, while carbon dioxide, a waste product from cells, is removed from the blood and exhaled.The circulatory system is responsible for transporting blood throughout the body. It carries oxygen-rich blood from the lungs to body cells and returns oxygen-poor blood carrying carbon dioxide back to the lungs for gas exchange. This cycle is essential for maintaining the body's metabolic processes and homeostasis.which roles do enzymes play in cells
Answer:
Enzymes help cells digest food, extract energy from food, and Increases the rate of chemical reactions.
Explanation:
They increase the rate of chemical reactions. Enzymes can be used to break things down, or to make things up. Without enzymes, reactions in a cell would slow to a halt, to a point where the cell would die.
Enzymes act as biological catalysts in cells, speeding up chemical reactions needed for cellular function. They assist in synthesis for cell growth and repair as well as energy transfer.
Explanation:Enzymes play crucial roles in cells; they function as biological catalysts. This means that they speed up chemical reactions that take place within cells. For example, enzymes help break down larger molecules into smaller ones, such as in the process of digestion, where enzymes break down food into molecules small enough for the body to absorb.
Enzymes also take part in the process of synthesis, where they aid in building larger molecules from smaller ones, an integral part of cell growth and repair. Furthermore, they are involved in energy transfer within the cell. For every physical and chemical reaction that a cell needs to perform for its survival, there is generally an enzyme involved. The importance of enzymes in cells cannot be overstated; they are indispensable for proper cellular function.

Baruch is interested in the carbon cycle. He learns that carbon enters the forest from the atmosphere by the sugar-making process of
Answer:
Photosynthesis is a sugar making process in which carbon is used in the form carbondioxide from the atmosphere and water is absorbed by the plant from the soil. When these two materials combine with each other, it produces oxygen and glucose. Oxygen is released in the atmosphere while glucose which is a monosaccharide is stored in different parts of plant body such as roots and stems.
Answer:
Photosynthesis.
Explanation:
In photosynthesis; 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
Here: CO₂ is carbonioxide, H₂O is water ==> Reactants
C₆H₁₂O₆ is simple sugar, O₂ is Oxygen ==> Products
Plants use their chlorophyll to trap Light energy that they use in breaking down the combination of "water" and "carbon dioxide".
The result of this process is "Simple Sugar" and Oxygen is emitted as the by-product.

What does vectors mean?
Final answer:
A vector is a quantity with magnitude and direction. Displacement, velocity, acceleration, and force are all examples of vectors. The direction of a vector can be given by a sign in one-dimensional motion, but in two dimensions, we use a reference frame and an arrow representation.
Explanation:
A vector is a quantity that has magnitude and direction. Displacement, velocity, acceleration, and force, for example, are all vectors. In one-dimensional, or straight-line, motion, the direction of a vector can be given simply by a plus or minus sign. In two dimensions (2-d), however, we specify the direction of a vector relative to some reference frame (i.e., coordinate system), using an arrow having length proportional to the vector's magnitude and pointing in the direction of the vector.
When roan cattle are mated, 25% of the offspring are red 50% are roan and 25% w e upon
examination, it can be seen that the coat of a roan cow consists of both red and white hans by what
this trait controlled?
A Multiple alleles
B Co-dominant alleles
C. Incomplete dominance genes
D. Dominant inheritance
Answer: B Co-dominant alleles
Explanation: The coat of a roan cow consists of both red and white because the two alleles are codominant. Codominance occurs when two alleles outwardly express themselves equally. In codominance, neither of the allele is completely dominant rather they are equally dominant. None is able to mask the effect of the other. The two alleles express themselves equally in the phenotype of the organism. This means that in a roan cow, the allele for white fur is dominant and the allele for red fur is equally dominant, thus they manifested equally as a mixture of both red and white furs.

The answers are a,b,c,e on edge.
Answer:
C. transfers water into Earth’s oceans.
E. moves oxygen and carbon dioxide through the biosphere.
Explanation: Atmosphere has great effect on the movement of water. Due to evaporation, water that is present in the ocean is evaporated in the form of vapours and forming clouds. These clouds move to the hilly areas and falls in the form of rain. This water is used by both plants and animals.
Atmosphere moves oxygen and carbon dioxide through the biosphere. Carbondioxode is exhaled from animal's body to the atmosphere. This carbondioxode is used by plants in the process of photosynthesis and make their own food and oxygen is exhaled. This oxygen is used by the animals.

This graph shows a population of mice in an ecosystem in which mice are not allowed to enter or leave.
Which statement best describes the population at point C?
A.) it’s death rate is higher than its birthdate.
B.) it is at it’s carrying capacity.
C.) it is decreasing in size.
D.) it’s growing rate is slowing down.
Assuming point C on a population ecology graph often represents a maximum sustainable population level, the best answer could be that the mouse population is at its carrying capacity. However, the lack of a visible graph makes it difficult to provide a definitive answer.
Explanation:Without the graph, it is tricky to determine the accurate answer; however, let's make assumptions based on what 'point C' could typically denote in population ecology graphs. Often, 'point C' could refer to a moment when the population reaches its carrying capacity. The carrying capacity is the optimum population size that the environment can sustain indefinitely, given the available resources. At this point, the population's growth rate tends to slow and stabilize, indicating that the birth rate is approximately equal to the death rate. Thus, we could infer that option B (it is at its carrying capacity) might be a fitting answer. However, without the graph, this is only an assumption and may not align with your specific scenario.

#SPJ2
The correct option is D.
At point C, the population's growth rate is slowing down as it approaches the environment's carrying capacity.
Based on the typical shape of a logistic growth curve in population ecology, the graph shows the size of a population as it grows over time. The S-shaped curve represents how the population size changes in response to the carrying capacity of the environment.
At point C:
1. **Death Rate vs. Birth Rate:** The death rate is not necessarily higher than the birth rate at point C. The population size at this point is still increasing, which means that the birth rate is likely equal to or greater than the death rate.
2. **Carrying Capacity:** The population is not at its carrying capacity at point C. The carrying capacity would be represented by the upper horizontal asymptote of the curve, which the population approaches but does not surpass.
3. **Decreasing in Size:** The population is not decreasing in size at point C; it is increasing. This is indicated by the upward trend of the curve.
4. **Growth Rate Slowing Down:** The growth rate of the population is indeed slowing down at point C. This is characteristic of the logistic growth model, where the rate of population growth slows as the population size approaches the carrying capacity of the environment due to factors like limited resources and increased competition.
Therefore, the statement that best describes the population at point C is Its growth rate is slowing down.
how does speciation and extinction affect the biological diversity of an ecosystem
Answer:
Specitation increases biodiversity, while extinctions decrease biodiversity.
Explanation:
Biodiversity is the variety of life on Earth or some specified geographic area of the planet; the diversity of life occurs at the genetic level, at the species level, at the ecosystem level, and in evolutionary lineages.
Speciation increases biological diversity in an ecosystem by introducing new species. For instance, allopatric speciation can lead to new bird species. Conversely, extinction decreases diversity, like when deforestation causes a plant species to cease existing.
Explanation:Speciation and extinction play substantial roles in shaping the biological diversity of an ecosystem. Speciation is the evolutionary process by which new biological species arise. This increases biodiversity by adding new species to the ecosystem.
For instance, if a population of birds splits into two distinct groups due to geographical separation and eventually evolve into separate species, this can lead to increased diversity. This whole process is known as allopatric speciation.
In contrast, extinction leads to a decrease in biodiversity. Extinction is the termination of a species, which means the total population of that particular species ceases to exist. For instance, if a species of plant becomes extinct due to deforestation, it will reduce biodiversity as it will no longer contribute to the total number of plant species in that ecosystem.

compare and contrast the effects of inavasive species, speciation and extinction biodiversity
Answer:
Modern invasive species are characterized by broad environmental tolerances, which contribute to their ability to survive during both the transport and establishment phases of invasion. Studies of modern and invasive species have demonstrated that invader species regularly displace native species through higher resource efficiency or competitive ability. A striking feature of the biogeographic pattern is the differential survival of species with large geographic ranges. Species with larger geographic ranges tend, on average, to have broader ecological tolerances than those with small ranges.

The diagram below shows a process that occurs in cells.
Which process is shown in the diagram?
A. diffusion
B. recombination
C. respiration
D. translation
Given the contexts and options provided, the most likely process depicted in the missing diagram is diffusion. Diffusion is a biological process crucial for several functions in a cell involving movement of particles from an area of high concentration to one of lower concentration.
Explanation:Without seeing the diagram it's difficult to definitively answer your question, but given the options and assuming that the diagram involves the movement of substances in cells, the most likely process it is representing would be diffusion. Diffusion is a biological process that moves particles from an area of high concentration to an area of lower concentration until they balance out.
Diffusion is crucial for many functions within the cell. For instance, the process of gas exchange during respiration occurs primarily through diffusion, where oxygen molecules move from a high concentration in the lungs to a lower concentration in the blood. Similarly, it facilitates the movement of glucose through the cell membrane. Also, substances that are small and nonpolar can easily diffuse through the lipid bilayer of the cell.
Processes like recombination, respiration, and translation involve more complex mechanisms and mostly specific to DNA operations or energy generation in the cells but not generalized movement of substances, unlike diffusion.

1. Gene regulation is the ability of an organism to control which genes are transcribed.
Gene regulation is the ability of an organism to control which genes are transcribed is a true statement.
Explanation:
Gene regulation is a process which regulate (by inducing or repressing) a gene expression.
It can make structural or chemical alterations to the gene material. It regulates transcription by allowing proteins to bind only to specific elements on the DNA and modulates translation.
Gene regulation simply turns genes “on or off”. The regulation action is done by activator proteins which induces or turns on a gene expression; while gene regulators repress or turns off the gene expression.
When a gene is turned on, it is ordered to code only for the specific protein. Only the respective required genes are turned on to specifically code for the specific proteins.
Thus the proteins can be coded into various types according to the function to be performed. The function and structure of a protein in a brain cell differs from that of a skin cell due to gene regulation .
Gene regulation is the ability of an organism to control which genes are transcribed, ensuring that the correct proteins are made when and where they are needed. This regulation occurs at various stages of gene expression, including transcription, where regulatory proteins bind to regulatory elements.
Explanation:Gene regulation refers to the ability of an organism to control which genes are transcribed, or expressed, in order to produce specific proteins at the proper time and in the correct amounts. This regulation ensures that the correct proteins are made when and where they are needed in an organism. It occurs at various stages of gene expression, including transcription, where regulatory proteins bind to regions of DNA called regulatory elements to either promote or impede transcription.

Explanation:
The regulation of gene expression is the central dogma of life. It is a series or set of mechanisms in which genetic information in the DNA expresses in the form of RNA or protein. Cells give gene expression b different mechanisms as transcription, maturation of mRNA, and translation.
During these mechanisms, different gene-regulatory proteins are influenced. For example, a set of RNA polymerases that are proteins transcribe the DNA molecule during transcription. Transcription factors are also proteins that control the synthesis of proteins in the cell. These proteins are an enzyme that catalyse the gene regulation in the human cells.
