Explanation:

Prokaryotic cells differ from eukaryotic cells in that they lack any membrane-bound organelles, including a nucleus. Instead, prokaryotic cells simply have an outer plasma membrane, DNA nucleoid structure, and ribosomes.

Watching CrashCourse video, I learned the 3 basic elements of taxonomy, which are the three domains are Archea (formed by prokaryotic beings, such as archaea), Bacteria (formed by prokaryotic beings, such as bacteria and cyanobacteria) and Eukarya (formed by eukaryotic beings).

Taxonomy is the branch of biology responsible for identifying and classifying all animals and plants that inhabit the Earth, based on the different characteristics they share with each other.

Taxonomy is the area of Biology that classifies, organizes and describes living beings. It is like a library that organizes each group into its categories, in an order that facilitates understanding and searching for features.

With this information, we can conclude that Taxonomy is a method used in biology to name, identify and classify living beings.

Answer: The process by which green plants and some other organisms use sunlight to synthesize from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

Answer: C

Explanation: Amino acids are not one of the four biomacromolecules. The biomacromolecules are nucleic acids, protiens, carbohydrates, and lipids.

Amino Acid is not one of the major biomacromolecules. Amino acids are the micro molecules that join to form proteins by peptide bonds.

Biomacromolecules are the kind of biomolecules. Biomolecules are the substances made inside the cells of the living body.

Biomolecules are further classified into Biomacromolecules and Bio micro molecules.

Biomacromolecules are  biomolecules having a size of 800 to one thousand Daltons, high molecular weights and complex structures. They are biological polymers of various simple or monomeric units.

Biomacromolecules includes the primary metabolites and secondary metabolites. Macromolecules are acid soluble and their molecular weights range from 18 to 800 Da.

Macromolecules are biomolecules that are characterized by their acid insoluble property.

Lipids are an exception because despite having molecular weight of less than 800 Da, they are classified as biomacromolecules owing to their acid insoluble property. Hence, lipids don't seem to be strictly macromolecules.

Example of biomacromolecules are: Proteins, Carbohydrates, Lipids.

Proteins:

They represent the bulk of biomolecules in a cell.

They are fashioned of simpler units known as amino acids that are linked together by covalent bonds known as peptide bonds. There are twenty one different types of amino acids.

Proteins are responsible for several functions within the body and thus they are classified into different types based on their function e.g.  structural proteins, enzyme proteins, transport proteins etc.

Proteins have a complex structure that divides into the Primary structure, Secondary structure and tertiary structure.

Carbohydrates:

Carbohydrates are biomolecules that primarily contain carbon, hydrogen and oxygen conjointly referred to as as sugars.

Carbohydrates are classified into totally different classes reckoning on the number of monomer units present in them such as monosaccharides(single monomer unit), disaccharides( two monomer units), polysaccharides(multiple monomer units).

Monosaccharides produce other names e.g. glucose, fructose

Monosaccharides have other names e.g. glucose, fructose.

Glucose is the energy currency of the cells in animals and fructose is in plants. These sugars contain an aldehyde group or a keto group and the bond between these groups and an alcoholic group of another monomer unit is known as a glycoside bond or linkage.  

Polysaccharides are primarily of two types: structural and food storage

Amino acids are organic compounds that contain amino carboxylic acid  functional groups, along with a side chain (R group) specific to each amino acid.

Amino Acid was discovered in 1806 by Louis-Nicolas Vauquelin and Pierre Jean Robiquet who isolated a compound from asparagus that was afterward named asparagine, the first amino acid.

Uses of Amino Acid:

- In industrial area

- Use in expanding Genetic Code

- Usage in biodegradable plastics

- As chemical Building blocks

Amino acid is a monomer that creates proteins.

Amino acids are organic molecules containing an amino group, a hydroxyl group, and a carbon side chain.

All amino acids share the same basic structure. However, they differ in their carbon side chain.

Amino acids are either non-essential or essential where non-essential amino acids are synthesized inside the human body from glucose mainly so it is not essential to get them from the diet.

Whereas essential amino acids don't seem to be synthesized within the body so that they should be obtained from the diet.

Answer:

answer!!

Explanation:

In the described experimental setup, information moves between organisms through visual observation and behavioral responses. Here is a breakdown of the information flow:

Visual Observation: The female cichlid fish in the central tank can observe the males in the tanks on either end through the transparent barriers. This allows the female to visually assess the males' characteristics, such as their size or coloration.

Behavioral Responses: Based on the visual information received, the female cichlid fish exhibits a mating preference by depositing eggs in the spawning nests that are closer to the larger male. This behavior indicates that the female is selecting the male with certain traits that she finds desirable.

The results of this experiment suggest that female cichlid fish have a mating preference for larger males. Out of the 20 repeated trials, in 16 cases, the females chose to deposit their eggs in the spawning nests closer to the larger male. This preference indicates that larger males may possess traits that are favored by the females during the mating process.

In terms of evolution, these results are consistent with the concept of sexual selection. Female cichlids choosing larger males for reproduction can lead to differential reproductive success. Larger males may possess genetic or phenotypic advantages, such as enhanced fertility, better parental care, or increased fitness. As a result, their genes have a higher chance of being passed on to future generations, leading to the evolution of traits that are preferred by females.

This experiment provides insights into the role of mate choice and sexual selection in cichlid fish, highlighting how the preferences of females can influence reproductive success and contribute to evolutionary processes.

Answer: (b). phospholipid molecules are not covalently bonded to each other

Explanation:

Phospholipids are the structures which are typically made up of a phosphate group and lipid tails which are usually fluid. It should be noted that phospholipids are a regarded as a form of lipids i.e the molecules that are made up of hydrocarbons.

They're gotten from fatty acids and theyre vital components of the cell membrane. The property of the phospholipid bilayer allows proteins to move laterally in the membrane is that phospholipid molecules are not covalently bonded to each other. Some common phospholipids include phosphatidylcholine, phosphatidylinositol, etc.

Therefore, the correct option is B.

Yes, it is true that pitcher plants are carnivorous. Pitcher plants are a type of carnivorous plant that have evolved to obtain essential nutrients from insects and other small organisms.

The answer in True.

These plants typically grow in nutrient-poor soil conditions and have adapted to capture and digest insects as a way to supplement their nutrient intake.
The main feature of pitcher plants is their modified leaves, which form a pitcher-like structure. This structure is filled with a liquid that contains enzymes and other substances that can break down the captured prey. The rim of the pitcher, called the peristome, is slippery, causing insects to fall into the trap. Once trapped, the insects are digested, and the nutrients are absorbed by the plant.
There are several types of pitcher plants, including the North American Sarracenia, the tropical Nepenthes, and the Cephalotus from Australia. Each species has unique adaptations and trapping mechanisms that help them capture different types of prey.
In summary, pitcher plants are indeed carnivorous, as they have adapted to obtain essential nutrients from insects and other small organisms. They do so through their unique pitcher-like structures, which are designed to trap and digest prey. This adaptation allows them to thrive in nutrient-poor soil conditions.

The answer in True.
