Answer:

Polymers are formed by two main ways called addition and condensation polymerization. In addition, polymerization, an initiator (or catalyst) reacts with a starting monomer. The result of this initiation reaction is a monomer attached to the initiator with an unsatisfied bond

Explanation:

A) Euglenozoans are eukaryotic organisms that belong to the Kingdom Protista. They are either free-living or parasitic in nature. They have no cell wall in their structure but instead possess a pellicle.

B) Diatoms are photosynthetic algae that belong to the division-Bacillariophyta. The ability to photosynthesize makes them a primary producer in an ecosystem. Their cell wall is made up of silica, which is unique to their group of algae. They also produce oils to maintain buoyancy.

C) Brown algae belong to the division- Phaeophyta. They exhibit alternation of generations in their life cycle where they produce both motile zoospores and sperm.

D) Apicomplexans are organisms such as plasmodium etc that belong to the phylum- Apicomplexa. Most of them are pathogenic, with some affecting humans. They lack cell wall but have a flat vesicle called ALVEOLI.

E) Green algae belong to the division Chlorophyta. They are photosynthetic organisms and exists as unicellular or colonial organisms. They have flagellated for locomotion.

B

Explanation:

The adult is fully developed so the genetics could pass on

Answer:

Water is hypotonic compared to the inside of the egg; there are more solutes in the egg than in the water. Because water moves down its concentration gradient, it moves from the distilled water into the egg. It will continue to move in this direction until there is an equilibrium between the inside of the egg and the surrounding water. This increases the mass of the egg.

Corn syrup is hypertonic to the inside of the egg. Again, water moves down its concentration gradient from the inside of the egg to the solution. This will decrease the mass of the egg.

The reason solutes do not move, instead of water, in these situations is because the egg shell (assuming it is like a chicken egg) does not allow solutes to pass though it. Only water is able to move through the shell.

Force is defined as an outside force that has the potential to alter how a body is moving or resting.  A force is not something an object "has in it" or that it "contains." One thing experiences a force from another. The idea of a force encompasses both living and non-living things. The body can change its size, shape, and direction when force is applied. As we discovered in a previous session, forces are significant because they induce modifications to motion.

Net force is defined as all of the forces pulling on a thing combined. The net force, which is a single force, replaces the original forces' influence on the particle's motion. The top 5 words that are similar to "net force" in terms of this word similarity engine are resultant force, force, acceleration, physics, and rotation.

Thus, the surface is the student not able to move the box is D.

Answer:

Heterotrophs obtain energy by eating plants and animals. Plants are autotrophs, absorbing the sun's energy through photosynthesis and making glucose. Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose.

The group of foods that would test positive for starch in the presence of iodine would be noodles, bread, or crackers.

Noodles, bread, or crackers consist largely of starch. Starch has the capacity to turn the brown color of iodine to blue-black because the iodine molecules insert themselves in the structure of the amylose content of the starch.

Foods like steaks, hard-boiled eggs, and chicken are essentially made of proteins and will, therefore, fail the iodine test for starch.

Explanation:

In order for one to have a recessive trait, both parents must carry the trait.

XX Xy= XX XX Xy Xy

Xy Xy= XX Xy Xy YY

XX XX= XX XX XX XX

yy yy= yy yy yy yy

Only the options in which both parents have the allele can pass it on. Only if there is no dominant allele will the trait be expressed, which can only be a yy recessive (since heterozygous would be dominant). Therefore, he will pass the allele on to his/her offspring.

Answer:

A. Oxygen ( for animals )

B and C ( for plants )

Explanation:

Cellular nutrients come in many forms, including sugars and fats. In order to provide a cell with energy, these molecules have to pass across the cell membrane, which functions as a barrier — but not an impassable one. During cellular respiration, oxygen is needed. Carbon dioxide is the product of cellular respiration.

In the event you are referring to plants, then both water and carbon dioxide are needed for photosynthesis.

Oxygen is required by all cells in order to function properly. Thus, the correct option is A.

Cells may be defined as the building blocks of living organisms. They are considered the basic structure and functional unit of life. All living beings are made up of cells.

Antony von Leeuwenhoek discovered the living cell for the very first time in 1674 with the help of an improved microscope in Pond water.

Cells require oxygen because they have the ability to break down food particles in the presence of oxygen to derive energy for metabolic activities. This process of breaking down food in the presence of oxygen is known as cellular respiration.

This is because oxygen functions as a final electron acceptor in the electron transport chain to synthesize an energy molecule known as ATP.

Therefore, Oxygen is required by all cells in order to function properly. Thus, the correct option is A.
