Answer;
-Pellicle
Explanation;
-Protist cells may contain a single nucleus or many nuclei; they range in size from microscopic to thousands of meters in area. Protists may have animal-like cell membranes, plant-like cell walls, or may be covered by a pellicle.
-On a paramecium's exterior is found the pellicle. The pellicle is stiff to maintain the paramecium's shape and provide stability but it is also flexible to allow movement. It also acts as an attachment site for external organelles such as cilia.
Answer:
Pellicle.
Explanation:
Malaria is the most significant parasitic disease of human. The disease is caused by protozoan of the genus Plasmodium. The most serious malignant malaria is caused byPlasmodium falciparum. It is transmitted by the female Anopheles mosquito. Plasmodium is a protist that cause malaria. Different types of species of the plasmodium are: P.vivax, P.malaria, P.ovale and P.falciparum which causes the most serious malignant called malaria.
Protist have animal-cell like membrane and is plasmodium is the example of protist. Its contain single nuclei or many nuclei. On a paracium exterior found a pellicle. Pellicle is a layered structure which surrounds the cells in many types of protozoa and also surrounds the cytoplasm. It is the non-extracellular like the cell wall of plants.
(B) Separation of homologous chromosomes
(C) Crossing over
(D) Separation of sister chromatids, with one chromatid pulled toward each pole
(E) Assembly of chromosomes along the equatorial plane
Answer:
Chloroplast
Explanation:
Chloroplasts are organelles, small organs of plant cells, and other organisms capable of photosynthesis, such as algae.
They are green in color because of the presence of chlorophyll. It is in chloroplasts that the chemical reactions of photosynthesis occur.
In addition, these structures have DNA, RNA and ribosomes, so they can multiply and synthesize proteins naturally.
A chloroplast is a type of plastid in plants that contains chlorophyll for photosynthesis. This process uses sunlight, carbon dioxide, and water to produce glucose and oxygen. The chlorophyll appears green because it absorbs blue and red wavelengths of light but reflects green.
The plastid with chlorophyll in plants that photosynthesize is called a chloroplast. Chloroplasts are plant cell organelles that contain a green pigment called chlorophyll, which captures the energy of sunlight for photosynthesis. This process involves a series of reactions that use carbon dioxide, water, and light energy to make glucose and oxygen.
Photosynthetic eukaryotes, including plants and some protists, possess these chloroplasts. However, some bacteria also perform photosynthesis, but their chlorophyll is not located in chloroplasts but instead, within the cell itself.
All photosynthetic organisms contain a pigment called chlorophyll a, which humans perceive as green. This is because it absorbs wavelengths from either end of the visible spectrum (blue and red), but not green, which is reflected, making chlorophyll appear green.

b. incomplete dominance.
c. codominance.
d. complete dominance.
I would say the answer is: Co-dominance
When I was taking biology I learned that there are 3 types of alleles.
You have IA, IB, and little i. The little i means it is a recessive trait. IA and IB are co-dominant. There's a lot more gibberish language I could use.
Good luck and hopefully this helped. If you need me to go into greater detail just let me know.
The right answer for the first gap is monomer.
The right answer for the second gap is polymer.
The polymer is a large molecule consisting of basic units called monomers (or monomer units) connected by covalent bonds.
A monomer is a compound of simple molecules that can react with other monomers to give a polymer.
If 15% of a DNA sample is made up of thymine, T, then the percentage of the sample that is made up of cytosine, C is 35%.
DNA stands for deoxyribonucleic acid. It may be characterized as the type of molecule inside cells that contains the genetic information responsible for the development and function of an organism. It is considered one of the most common types of genetic material.
According to Chargaff's rule, the amount of adenine is always equal to the amount of thymine while the amount of guanine is always equal to the amount of cytosine.
The amount of thymine in a DNA sample = 15%
Then, the amount of adenine = 15%
Total amount of DNA = 15 +15 = 30%.
The amount of DNA left = 70% which holds guanine and cytosine in equal amounts. So, the amount of guanine = 35%, and the amount of cytosine = 35%.
Therefore, if 15% of a DNA sample is made up of thymine, T, then the percentage of the sample that is made up of cytosine, C is 35%.
