Answer/Explanation:
The cell cycle consists of interphase and mitosis (M). Within interphase, there are three phases: G1, S, and G2.
G1 phase - the first 'gap' phase.The cell grows in size, and synthesises the necessary mRNA and proteins required to divide. This is also where the key decision as to whether the cell will divide takes place. This is based on whether or not the environmental conditions are favourable for division and whether the cell is receiving the correct signals to divide. This is called the G1/S transition, and is the critical decision making point as to whether the cell cycle will progress.
S phase - the 'synthesis' phase. The cell replicates its DNA in preparation for passing the genetic material onto the daughter cells. Once the cell's DNA is replicated, it enters G2.
G2 phase - the second 'gap' phase. The cell continues to grow in size and prepare for mitosis. There is a DNA damage checkpoint here, where the cell ensures that the DNA has properly replicated. Next, it moves into mitosis (M).
M phase - the mitosis phase. This consists of 4 stages (PMAT) - prophase, metaphase, anaphase, telophase. The cytoplasm divides during cytokinesis
During prophase the chromosomes condense and pair up. The mitotic spindle forms, and the nuclear membrane disappears. During metaphase, the chromosomes line up at the centre of the cell - at the metaphase plate. The mitotic spindles attach to the chromosomes - to each sister chromatid.During anaphase, the sister chromatids are pulled apart to opposite poles of the cellDuring telophase, two new nuclei form, surrounding the two new sets of chromosomes. Cytokinesis then occurs, pinching the membrane to create two new cells.which of the following is an example of an indirect observation

A chemical compound is considered to be a pure substance. This is because each molecule of the chemical compound has the same chemical formula.
Answer:
A compound is a pure substance composed of two or more different atoms chemically bonded to one another. A compound can be destroyed by chemical means. It might be broken down into simpler compounds, into its elements or a combination of the two.
Explanation:
Answer:
Sample Answer: Even though a compound can be made of two or more types of atoms, it is still a pure substance because the compound can be isolated, like salt or water.

A student calculated the average surface area-to-volume ratio of four different types of human epithelial cells. The results are shown in the table below. Based on the data, which type of cell would be best suited for lining the alveoli of the lungs, where diffusion of carbon dioxide and oxygen must occur very rapidly? Simple squamous cells Simple cuboidal cells Simple columnar cells Simple spherical cells
Answer:
There is no data attached to this question, however, the question can be answered based on general understanding of epithelium tissues.
The answer is Simple squamous cells
Explanation:
Epithelial tissues are those tissues that line or cover the surfaces of walls or structures. However, based on the one cell layer and their shape, which defines their function, epithelial tissues are classified into the following:
- Simple squamous
- Simple cuboidal
- Simple columnar
All the above have one cell layer. This question involves a student that calculated the average surface area-to-volume ratio of four different types of human epithelial cells. Based on the question, SIMPLE SQUAMOUS CELLS would be best suited for lining the alveoli of the lungs, where diffusion of carbon dioxide and oxygen must occur very rapidly.
This is because the simple squamous cells, which are shaped like the scales of a fish, are thin-walled flat cells. Hence, they are found or adapted to parts where where diffusion or filtration takes place e.g alveoli of the lungs

You have explored some informative examples of models. Now it's time to get creative and make your own model. Here is the requirement checklist for your model:
Model types can include drawings, diagrams, physical models, virtual simulations, or videos.
Model must be created by you, not something selected from an online or outside source.
Submit a presentation, picture, video, or screenshot of your model.
Submit a one-paragraph summary describing the topic you chose, your model, what it represents, how you made it, and the specific science involved. It is important that you are using science terminology and are accurate.
there are three topics, I chose cellular respiration but you can do carbon cycle or photosynthesis if either of them is easier

Answer:
B. cell wall
Explanation:
After a protein is made in the endoplasmic reticulum of an animal cell, it A) attaches to a ribosome on the ER membrane to be encoded and used in DNA replication B) is sent to the Golgi apparatus to be processed, stored, and sent to another destination C) is stored in the large central vacuole until it is needed by the cell for growth and repair D) travels to the mitochondria to be broken down and used for energy to power the cell
Answer:
B) is sent to the Golgi apparatus to be processed, stored, and sent to another destination
Explanation:
Proteins are important biomolecules produced in the cells of living organisms, specifically the Rough Endoplasmic reticulum (RER) attached to the ribosome (site of protein synthesis).
However, after production by the RER, the protein is sent to an organelle called the Golgi apparatus in order to be processed, stored, and sent to another destination by transport vesicles.

How is nitrogen pollution processed by the wetland
Answer: In the wetland, nitrates are absorbed by plants or converted (through an anaerobic process called denitrification) to nitrogen gas and lost to the atmosphere. Nitrate-N is efficiently removed from wetland surface waters by aquatic plants. Ammonium-N enters wetlands primarily through surface runoff.
how do mountains influence climate?
Answer:
Explanation:
They affect climate by blocking wind and receiving more rainfall than low-lying areas. As air is forced over higher ground, it cools, causing moisture to condense and fall as rain. The higher a location is above sea level, the colder it is.
Answer:
Mountains can affect the climate of nearby lands. In some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. Much of airborne moisture falls as rain on the windward side of mountains.

What is the purpose of using a pedigree?
to study the causes of traits that are acquired during an organism's life
to understand patterns of inheritance in organisms
to determine mating patterns in organisms
to identify traits that are acquired during an organism's life'
Answer:
B) to understand patterns of inheritance in organism
Explanation:
The pedigree's purpose is to understand patterns of inheritance in organism. Examination of the pedigree utilizing the standards of Mendelian legacy can decide if a characteristic has an overwhelming or passive example of legacy. Families are frequently built after a relative harrowed with a hereditary issue has been distinguished.
The purpose of using a pedigree is to understand patterns of inheritance in organisms. Therefore, the correct statement is option B.
What is a pedigree?A pedigree is a diagram showing the relationships between family members and their inheritance of specific traits. The pedigree of a family is studied from which scientists can analyze the patterns of inheritance for a particular trait, which can be dominant or recessive, and the inheritance of trait from one generation to the next generation.
Pedigrees identify individuals who may have any genetic disease or trait, and can predict the particular trait in future generations also, Scientists also understand the inheritance of complex traits controlled by multiple genes and environmental factors.
Pedigrees are used in human genetics for studying the inheritance of genetic diseases and inheritance patterns in other organisms, such as plants to better understand the genetic basis of traits.
Therefore, the purpose of using a pedigree is to understand patterns of inheritance in organisms.
