Answer:
prophase-during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears
Metaphase-during which the chromosomes become attached to the spindle fibers.
Anaphase-which the chromosomes move away from one another to opposite poles of the spindle.
Telophase-in which the chromatids or chromosomes move to opposite ends of the cell and two Identical nuclei are formed.

What is the boundary that
separates a cell from the inside and outside environment?
Answer:
plasma membrane
The plasma membrane (often called the cell membrane) is a thin flexible barrier that separates the inside of the cell from the environment outside the cell and regulates what can pass in and out of the cell. Internally, the cell is divided into the cytoplasm and the nucleus.

Answer:
The correct answer is -a common characteristic (in a logical manner)
Explanation:
The six kingdom classification is given by Woese et al 1977, the basis of this classification was the shared characteristic of organisms. These common characteristics include more than one character such as cell type ( prokaryotic or eukaryotic), type of nutrients (autotrophs, heterotrophs), type of reproduction, homologous or analogous organs, habitat, and many more.
All these traits or characters helped in grouping organisms in a logical manner and is one of the most acceptable classifications.
Thus, the correct answer is -a common characteristic (in a logical manner)

Which is an organelle that performs photosynthesis and is paired with its correct function?
A) Chloroplast-converts light energy into chemical energy.
B) Chloroplast-converts chemical energy into light energy.
C) Mitochondrion-converts cellular energy into glucose chemical energy.
D) Mitochondrion-converts energy found in glucose into energy for cells.
Answer:
A
Explanation:
Plants absorb the light and turn it into chemical energy with the help of chloroplasts
Chloroplast is the organelle in the plant cell which converts light energy into chemical energy. Chloroplast performs photosynthesis. Thus, the correct option is A.
What is Chloroplast?A chloroplast is a type of membrane-bound organelle which is known as a plastid which conducts photosynthesis mostly in the plant cells and algal cells. Chloroplast are the organelles which convert the light energy into chemical energy in the form of carbohydrates (sugar). The photosynthetic pigment chlorophyll is present in the chloroplast which captures the energy from sunlight, converts it, and stores it in the energy-storage molecules such as ATP and NADPH while freeing up the oxygen molecule from water in the cells.
Chloroplast is the double membranous organelle which is present in the plant cells and certain algal cells. This organelle is absent in the animal cells. Thus, they cannot perform photosynthesis.
Therefore, the correct option is A.

Give the symbols for the element that makes up each of the following:
______Carbohydrates.______ Lipids. _____DNA. _____Proteins.
Answer:
The correct answer is :
1. CHO
2. CHO
3. CHONP
4. CHON
Explanation:
Carbohydrates are composed of the carbon, hydrogen, oxygen in the ration of 1:2:1 which means hydrogen atoms are double than oxygen and carbon atoms. Carbohydrates are also known as sugars or polymer of sugars.
Lipids are composed of long chains of fatty acids made up of carbon, hydrogen, and oxygen molecules that are insoluble however ade up of organic molecules.
DNA or deoxyribose nucleic acid is the basic unit of cell and known as genetic material. It is made up of ribose sugar, a nitrogenous base, and phosphate backbone so elements that make these nutrients are Carbon, hydrogen, and oxygen with nitrogen and phosphorus.
Proteins are made up of amino acids that have carbon, hydrogen, oxygen, and nitrogen element in them.
The 4 macromolecules are namely Carbohydrates, Proteins, Nucleic acids, and Lipids. The composition of each macromolecule is defined by the elements present.
The symbols for the element that makes up each macromolecule are listed below:
Carbohydrates-H, C, and O(Hydrogen, Carbon, and Oxygen) Lipids-H, C, and O(Hydrogen, Carbon, and Oxygen) DNA-O, H, N, C, and P(Oxygen, Hydrogen, Nitrogen, Carbon, and Phosphorus) Proteins-O, H, C, and N(Oxygen, Hydrogen, Carbon, and Nitrogen)Thus, the symbols of the element that make up Carbohydrates, Proteins, Nucleic acids, and Lipids are defined.

What are bones?Bone is a solid bodily tissue made up of cells encased in a lot of dense intercellular substance. Collagen plus calcium phosphate, the two main components of this substance, set bone apart from other hard tissues like chitin, enamel, or shell. The individual bones that constitute the human spine or the skeletons of many other vertebrates are composed of bone tissue.
The mechanical stress of soft tissues, like the muscles contracting as well as the expansion the lungs, requires structural support from bone. Bone also protects soft tissues and organs, like the blood-forming system, and serves as a protective place for specialized tissues.
The largest part of the leg: muscle
Connects muscle to bone: tendon
Fills space between bones: cartilage
Connects bone to bone: ligament
Skeletal part of the leg: bone

What are the characteristics of the hot and dry deserts?Hot and dry deserts have extremely hot climates and challenging environments. There is very little biodiversity in hot deserts because of the harsh climate. Few species are specialized enough to survive there. Apart from this, the climate is very dry with less than 250 mm of rainfall a year.
According to the context of this question, cold deserts have extremely low temperatures and snowfall. While coastal deserts occur in cool to warm areas along the coast. They have cool winters and long, warm summers. Coastal deserts are located on the west coasts of continents between 20° to 30° latitude.
Therefore, the arid desert represents an example of the classic hot and dry desert. Thus, the correct option for this question is A.

two specific examples of radioactive isotopes being used as “spies”
Answer:
Carbon-14 in photosynthesis and Florbetapir (18F) in PIB of Alzheimer's disease.
Explanation:
These radioactive isotopes known as the biological spies as they tell or mark the presence or activity of a particular atom to the scientists in living beings.
For instance,
1. the process of photosynthesis can be understood by observing the radioactive isotope Carbon-14 from taking the carbon dioxide to the generation of glucose molecule by molecule process.
2. A protein that is deposited in people with Alzheimer's disease, called beta-amyloid. It is bind with another protein known as PIB, which contains Florbetapir (18F) a radioactive isotope. It gives an idea about the location of PIB and deposits in amyloid to try to eliminate the protein deposits and check the effect of medication.
