What are the differences between animal and plant cells?
Answers
Plant cells have them, animal cells do not.
Lmk if you need more differences
Answer: Animal cells and plant cells have several key differences in their structure and organelles. Here are some of the main differences between animal and plant cells:
Cell Wall: Plant cells have a rigid cell wall composed of cellulose, which provides support and protection. Animal cells lack a cell wall.
Chloroplasts: Plant cells contain chloroplasts, which are responsible for photosynthesis. Chloroplasts contain chlorophyll, the pigment that captures sunlight for energy production. Animal cells do not have chloroplasts.
Vacuoles: Plant cells typically have a large central vacuole that occupies a significant portion of the cell's volume. The vacuole stores water, nutrients, and waste products. Animal cells have smaller vacuoles, if any.
Shape: Plant cells often have a fixed shape due to the presence of the cell wall. Animal cells have a more flexible shape and can change their shape as needed.
Centrioles: Animal cells have centrioles, which are involved in cell division and the organization of the cytoskeleton. Plant cells lack centrioles.
Plasmodesmata: Plant cells have plasmodesmata, small channels that connect adjacent cells, allowing for communication and transport of materials. Animal cells do not have plasmodesmata.
Lysosomes: Animal cells contain lysosomes, which are organelles involved in the digestion of waste materials and cellular debris. Plant cells have fewer lysosomes or may lack them altogether.
Cilia and Flagella: Some animal cells have structures called cilia or flagella that are involved in cell movement. Plant cells generally lack cilia and flagella, although some exceptions exist.
It's important to note that while these differences highlight general characteristics, there can be variations in cell structures between different types of animal and plant cells.

Answers
N = 1.386 Ne. and the value of N is a little over 100. After 20 generations of random mating, the heterozygosity of the isolated wildflowers is half of what it was at the start. The effective population size formula that can be used is N e = (1/2H) 2N / (2NH - H).
According to the given statement, Diploid wildflowers from a large population are transplanted to a location where they are reproductively isolated from the original population. Their heterozygosity is measured each generation. After 20 generations of random mating, their heterozygosity is half of what it was at the start. The value of N must be estimated. We know that the effective population size is the size of the population that would have the same rate of genetic drift as the actual population.
The effective population size (N e) can be expressed as shown below:
Ne = 4N 1 N 2 / (N1 + N 2) In this formula, N 1 and N 2 are the number of organisms in the two populations.
Thus, after 20 generations of random mating, the heterozygosity of the isolated wildflowers is half of what it was at the start, indicating that: Heterozygosity after 20 generations = 1/2
Heterozygosity at the start or Heterozygosity at the start = 2 (Heterozygosity after 20 generations). The effective population size formula that can be used here is:
Ne = (1/2H) 2N / (2NH - H) Where H is the heterozygosity at the beginning and N is the effective population size.
We can use the Hint given in the question to find that the above equation is approximately:
Ne = (1/4) N/ ln (2) So, N/ ln (2) = 4Ne or N = 4Ne ln (2) ≈ 1.386NeThus, N ≈ 1.386Ne.
The value of N is a little over 100, which is what we can expect.
After 20 generations of random mating, the heterozygosity of the isolated wildflowers is half of what it was at the start. Therefore, the effective population size formula that can be used is N e= (1/2H) 2N / (2NH - H).
Thus, N ≈ 1.386 Ne. and the value of N is a little over 100.

are the genes determining the three traits assorting independently of each other? why/why not? use the probability associated with your chi square value to support your answer.
Answers
Answer:
why not
Explanation:
A shade-loving plant thrives underneath the trees in a forest. when the seeds of the plant are blown into areas where the plant receives direct sunlight, the seed sprouts but the young plant soon dies. if a series of mutations occurred in the plant that caused the plant to need more sunlight, when might the mutated plants survive?
Answers
The mutated plants might survive if the mutations result in adaptations that allow the plant to better tolerate or utilize direct sunlight.
Shade-loving plants have adapted to thrive in low light conditions by developing traits such as large leaves with a low surface area to volume ratio to maximize light absorption and photosynthesis in low light conditions. These adaptations are not beneficial in direct sunlight as they may cause the plant to overheat or lose too much water through transpiration.
If the series of mutations in the plant lead to adaptations such as smaller leaves with a higher surface area to volume ratio, increased production of protective pigments or the ability to utilize different wavelengths of light, the mutated plant may be better suited to survive and thrive in direct sunlight.
However, it is important to note that the process of natural selection is slow and not all mutations lead to beneficial adaptations. Additionally, the plant's survival in direct sunlight may also depend on other factors such as soil composition and water availability.

1. Cytokinesis in plant cells result in the formation of a cell plate between the new cells , while cytokinesis in animal cells only pinches the cell membrane in half.
Is this right?
Answers
Answer:
Yes it is right
Explanation:
Cytokinesis in plant cells results in the formation of a cell plate between the new cells, while cytokinesis in animal cells only pinches the cell membrane in half. This is a true statement. The cell plate forms the cell wall of the plant.
What is cytokinesis?The cytokinesis is a process by which the cell is divided into two daughter cells, each containing some of the cytoplasm of the parent cell. This process of cytokinesis is different in animals and plants. Animal cells' cytokinesis starts at the end of the telophase. Cell actin and myosine proteins pinch the cells, and as a result, the cell divides into halves.
In plant cells, there is no pinching mechanism. There is a cell plate formed in the middle of the dividing cell by the accumulation of the vesicles, cellulose, etc. Then daughter cells are formed.
Hence, it is a true statement that cytokinesis in plant cells results in the formation of a cell plate between the new cells, while cytokinesis in animal cells only pinches the cell membrane in half.

Mitosis and meiosis are different processes, but have some basic similarities. Which of the following describes an event that would take place in the process of meiosis, but not mitosis?
A.) Condensed chromosomes line up in the center of the nucleus in metaphase.
B.) The cytoplasm is divided between two cells through cytokinesis.
C.)There would be only one cell division resulting in two new cells.
D.) Chromosomes cross over and swap gene sequences.
Answers
This event occurs during meiosis, but not mitosis. During meiosis, homologous chromosomes pair up and exchange segments of genetic material in a process called crossing over. This results in new combinations of genes on the chromosomes, increasing genetic diversity. In contrast, mitosis does not involve the pairing of homologous chromosomes, and there is no crossing over.

The nerves in our spinal cord contain the necessary equipment to process our sympathetic and parasympathetic reflexes. What are these, and what do they do?
Answers
Answer: Your welcome!
Explanation:
Sympathetic reflexes are those that help to prepare the body for a “fight or flight” response, such as increased heart rate, increased respiration, and the release of adrenaline. Parasympathetic reflexes are those that help the body to relax and return to a resting state, such as decreased heart rate, decreased respiration, and the release of calming hormones. The nerves in our spinal cord are responsible for sending messages to the body in order to trigger these reflexes.
How do the internal structures of the tree function together to help a tree take in and lock up carbon atoms from carbon dioxide in the wood of the tree as it grows?
Answers
Answer:
CO2 is a basic element for plants because it is a key part of their nutrition. They take carbon dioxide from the atmosphere and, after the process of photosynthesis, break down the gaseous molecule to supply themselves with energy, release oxygen and incorporate carbon atoms into their tissues. The trees of the planet act as a sink, sequestering CO2 from the air and fixing carbon for hundreds of years in the form of wood. Carbon will be released after the tree dies, when it begins to decompose.The inner layer called phloem or bast , is made up of living cells and its function is to conduct the sugar-filled sap from the leaves to the rest of the tree.
Explanation:
Trees, through photosynthesis, retain CO2 that they keep in their "organism" throughout their life cycle until they decompose. In this way they convert carbon atoms in the atmosphere into glucose (what they use to grow), and exhale oxygen that they release into the environment. By photosynthesis, plants retain CO2, becoming its dry mass of 50% carbon. The CO2 that is produced inside the mitochondria during respiration ends up being released into the atmosphere after crossing multiple barriers. The CO2 emitted by a stem xylem parenchyma cell must first cross the membranes and cell wall; and once in the intercellular spaces of the trunk, it does not diffuse rapidly outwards, but is slowed down by the conductive elements of the xylem and by the cambium, the phloem and, finally, the outer cortex. In the xylem, the arrangement and structure of the conductive elements, as well as the structure of the membranes of the pits that connect the conductive elements and these radially with the parenchyma influence the permeability to the passage of CO2.

when activated, which direction do sodium ions flow through the cell?
Answers
Sodium ions flow into the cell from extracellular fluid when activated, due to electrochemical gradient established by cell membrane.
When enacted, sodium particles (Na+) stream into the cell from the extracellular liquid. This is a direct result of the electrochemical slope laid out by the distinction in particle fixation and electrical potential across the cell layer.The resting layer capability of a cell is negative within and positive outwardly.
At the point when an improvement sets off the kickoff of voltage-gated sodium channels, Na+ particles race into the cell, pulled in by the negative inside of the cell. This flood of positive particles depolarizes the film potential, setting off an activity potential and the transmission of a nerve motivation or muscle withdrawal.
In the wake of arriving at a pinnacle, the sodium channels close, and potassium channels open, permitting K+ particles to stream out of the cell, which returns the film potential to its resting state.

Nondisjunction that results in abnormal number of chromosomes can occur during.
Answers
Nondisjunction is the failure of chromosomes to separate properly during the anaphase stage of meiosis or mitosis, resulting in an abnormal number of chromosomes.
This can occur during both meiosis and mitosis.In meiosis, nondisjunction can occur during either the first or second meiotic division. During the first meiotic division, homologous chromosomes fail to separate, resulting in the formation of gametes that have an extra copy of one chromosome and a deficiency of the other. During the second meiotic division, sister chromatids fail to separate, resulting in gametes that either have an extra or a deficient chromosome.In mitosis, nondisjunction can occur during any division, resulting in cells with either an extra or a deficient chromosome.
If nondisjunction occurs early in embryonic development, it can result in a mosaic condition where some cells have an abnormal number of chromosomes while others have a normal number. Nondisjunction can have serious consequences, including genetic disorders such as Down syndrome, Turner syndrome, and Klinefelter syndrome. The likelihood of nondisjunction increases with maternal age, as the meiotic spindles become less efficient over time. In addition, certain environmental factors such as radiation exposure can increase the risk of nondisjunction.
