Answer:

This question lacks options, the options are:

A. The sequence of DNA determines the structure of lipids, which produce phenotypes.

B. The sequence of DNA determines the structure of proteins, which produce phenotypes.

C. The sequence of DNA determines the structure of phosphates, which produce phenotypes.

D. The sequence of DNA determines the structure of carbohydrates, which produce phenotypes.

The answer is B.

Explanation:

DNA is the genetic material found in the genome of living organisms. DNA holds the information needed for the synthesis of useful products in an organism. DNA contains segments called GENES that encodes the biological molecule, PROTEINS, which is responsible for the trait exhibited by organisms.

An example of trait in humans is human color, which is encoded by DNA. However, this DNA does not directly produce hair color in humans but the information held in it undergoes expression to produce protein called MELANIN, which is responsible for the hair color trait. Hence, the sequence of DNA determines the structure of proteins, which produce phenotypes (hair color).

Answer:

Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Proteins may be structural, regulatory, contractile, or protective; they may serve in transport, storage, or membranes; or they may be toxins or enzymes. Each cell in a living system may contain thousands of different proteins, each with a unique function. Their structures, like their functions, vary greatly. They are all, however, polymers of alpha amino acids, arranged in a linear sequence and connected together by covalent bonds.

Alpha Amino Acid Structure

The major building block of proteins are called alpha (α) amino acids.  As their name implies they contain a carboxylic acid functional group and an amine functional group.  The alpha designation is used to indicate that these two functional groups are separated from one another by one carbon group. In addition to the amine and the carboxylic acid, the alpha carbon is also attached to a hydrogen and one additional group that can vary in size and length.  In the diagram below, this group is designated as an R-group.  Within living organisms there are 20 amino acids used as protein building blocks.  They differ from one another only at the R-group position. The basic structure of an amino acid is shown below:

Figure 2.1 General Structure of an Alpha Amino Acid

There are a total of 20 alpha amino acids that are commonly incorporated into protein structures (Figure 2.x). The different R-groups have different characteristics based on the nature of atoms incorporated into the functional groups. There are R-groups that predominantly contain carbon and hydrogen and are very nonpolar or hydrophobic.  Others contain polar uncharged functional groups such as alcohols, amides, and thiols. A few amino acids are basic (containing amine functional groups) or acidic (containing carboxylic acid functional groups). These amino acids are capable of forming full charges and can have ionic interactions. Each amino acid can be abbreviated using a three letter and a one letter code.

El experimento se basa en analizar el movimiento de la planta en respuesta a la luz solar, desde distintas posiciones:

Durante su experimento, Pedro debe ir registrando los movimientos que observa en las distintas plantas a medida que recibe la luz del sol. El registro de dichos movimientos ante el estímulo forma parte de los resultados.

- Objetivo o propósito del trabajo: analizar la influencia de la luz solar como estimulo para generar un movimiento en plantas desde distintas posiciones.

- Procedimiento: Ubicación de plantas en distintas posiciones y bajo las mismas condiciones ambientales. Exposición de todas las plantas a la misma cantidad de radiación solar. Observación del movimiento durante un periodo de tiempo determinado.

- Resultados: Registro del movimiento de cada planta en cada posición durante el periodo de tiempo que fueron expuestas a radiación. En esta instancia de vuelca en tablas o gráficos, o se describe qué fué lo que se observó durante el experimento. Cuál fue la respuesta de cada una de las plantas.

- Conclusión: Relación entre lo esperado y lo observado. Comparación con otros trabajos similares.  

Answer:

Shadows are made by blocking light. Light rays travel from a source in straight lines. If an opaque (solid) object gets in the way, it stops light rays from traveling through it. This results in an area of darkness appearing behind the object. The dark area is called a shadow

Answer:

B. very high genetic variation

Explanation:

Selective breeding is the process by which crops or animals with desired phenotypic traits are chosen to produce offspring, which will contain the desired qualities. In this case, a group of scientists is trying to apply the principles of selective breeding to develop a particular crop plant.

This goal of producing a useful crop plant by the scientists can only be achieved when the plant species in question possess a HIGH GENETIC VARIATION i.e. difference in genetic constitution of individuals of the same species. This allows the individuals in the population to survive better.

Explanation:

Reservoirs which provide humans, animals, and plants with drinkable water are lakes, rivers, and groundwater.

A reservoir is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation.

All basic functions of a reservoir can be made use of: storage, water conservation, flood control, water treatment, and aquatic environment. Reservoir systems can be either single- or multi-purpose systems.

A dam and reservoir may support navigation, recreation, flood control, irrigation, and water supply, with each multipurpose benefit providing significant social and economic impacts on a local, regional, and national level.

C. in regions rich in resources we need to survive (ex. fertile land, water)

Explanation:

The possible genotype of all the offspring will be PP, and Pp as per the given situation.

An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries in a specific gene or genetic region are also referred to as the genotype.

The term "genotype" broadly refers to an organism's genetic make-up; in other words, it characterizes an organism's whole gene pool.

The phrase can also be used to describe to the alleles, or different forms of a gene, that an organism carries in a more specific meaning.

In the Punnett square attached, the genotype of the organism is PP and Pp, which means the generation will be having purple flower.

Thus, the possible genotype will be 50% PP and 50% Pp.
