Explanation:
For a certain plant, purple flowers (allele: P) are dominant and white flowers (allele: p) are recessive. A heterozygous purple plant is crossed with a true-breeding (purebred) white plant. What are the possible genotypes (allele pairs) of the offspring?
The possible genotype of all the offspring will be PP, and Pp as per the given situation.
What is genotype?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.

Go Deep! Look at the Parent Chromsomes and Key pictured below. Would it be possible for these parents to have a daughter with Hemophilia?
Answer: No, the daughter will be a carrier only.
Explanation: Hemophilia is a sex-linked recessive disorder. The recessive gene is carried on the X chromossome. Males have only one X chromossome, while females have 2. So, for a male individual to have hemophilia, it only needs the recessive gene to be on the X chromossome. In a female, the disorder is expressed when both X chromossomes has the recessive gene.
In the Parent Chromossomes picture shown, the father's X chromossome doesn't have the gene for hemophilia and the mother is heterozygous for the trait, i.e., she carries the recessive gene.
A daughter will inherit an X chromossome from the father and an X chromossome from the mother.
In this family, the daughter will inherit the X with dominant gene H for the father and has a possibility of inheriting another dominant gene H or recessive gene h from the mother.
For the daughter to be hemophiliac, she has to inherit 2 recessive genes. Since in either case she won't, she only inherits 1 recessive gene, the daughter will be a carrier for the trait, not have the disease.

The diagram below illustrates two different protein molecules found in organisms. Which of the following statements is not correct?
The proteins have different functions
The proteins are both composed of amino acids
The sequence of amino acids in both proteins are the same
The shapes of these proteins determine their functions.
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.

1. How will photosynthesis affect the dissolved oxygen levels in the
water?
Answer:
Vegetation- riparian vegetation directly affects dissolved oxygen by releasing oxygen into the water during photosynthesis. It indirectly affects dissolved oxygen concentrations because vegetation shading a stream may decrease water temperatures, and as temperature decreases dissolved, oxygen increases.

B) Polar ice caps, glaciers, and rivers
C) Lakes, rivers, and groundwater
D) Oceans, groundwater, and polar ice caps
Reservoirs which provide humans, animals, and plants with drinkable water are lakes, rivers, and groundwater.
What do you mean by reservoirs?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.

why is it important to know a person's rhesus Factor before a blood transfusion
A patient who is Rh+ can receive Rh- blood
A patient who is Rh- can receive Rh+ blood
A patient who is Rh+ can receive only RH+blood
A patient who is Rh- can receive only Rh- blood
Answer:
Rh negative can only receive Rh negative blood
Explanation:
When a person has Rh negative blood and receives a transfusion of Rh positive blood, the body does not recognize the antigen and attacks it as if it were an invader. This makes the person’s body essentially attack itself.
Team of scientists is studying several plant species that they think could become new farm crops. The scientists want to apply selective breeding to develop one of the species into useful crop plants. Which property of a plant species would be MOST USEFUL for meeting the scientists' goal? A. very low genetic variation B. very high genetic variation C. producing only a few fruits and seeds each growing season
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.

DNA is the hereditary molecule that determines hair color in humans. However, the DNA molecule itself is colorless. How does DNA determine the hair color of individuals?
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).
____________is when humans choose the traits of an organism.
