in pea plants, the allele for purple flowers is dominant over the allele for white flower color of one pea plant is represented by is the genotype? what is the phenotype?
The genotype of a pea plant with purple flower color would depend on the specific alleles present.
Let's assume that the allele for purple flowers is represented by "P" (dominant), and the allele for white flower color is represented by "p" (recessive).
If the pea plant has the genotype "PP" (homozygous dominant), it means it has two copies of the dominant allele for purple flowers. In this case, the phenotype (observable characteristic) would be purple flower color.
If the pea plant has the genotype "Pp" (heterozygous), it means it has one copy of the dominant allele for purple flowers and one copy of the recessive allele for white flower color. In this case, the phenotype would still be purple flower color because the dominant allele "P" masks the expression of the recessive allele "p".
However, if the pea plant has the genotype "pp" (homozygous recessive), it means it has two copies of the recessive allele for white flower color. In this case, the phenotype would be white flower color, as the absence of the dominant allele allows the expression of the recessive allele.
Therefore, to determine the genotype and phenotype of a specific pea plant with regard to flower color, we would need to know the specific alleles present in that plant.

A forensic scientist is trying to find out the number of adenine bases in the DNA sample that he obtained from a crime scene.
What can he assume about the number of adenine?
The number of adenine bases will be equal to the number of guanine bases.
The number of adenine bases will be equal to the total of all the other bases.
The number of adenine bases will be equal to the number of thymine bases.
The number of adenine bases will be half of the number of cytosine bases.
Answer:
The number of adenine bases will be equal to the number of thymine bases.
Explanation:
A DNA molecule is a double-stranded molecule made up of nucleotide bases. There are four (4) nucleotide bases that make up the DNA viz: Adenine, Guanine, Cytosine, and Thymine.
According to Chargaff, who postulated the complementary base pairing rule that states that I the DNA molecule, Adenine base always hydrogen bond with Thymine base and Guanine base always hydrogen bond with Cytosine base i.e. A-T, G-C. Chargaff also found out that the amount of Pyrimidines (Cytosine and Thymine) are equal to one another, likewise the Purines(Adenine and Guanine).
According to Chargaff, the number of Adenine base equals the number of Thymine base that it pairs while the same occurs for Guanine and Cytosine pair. All bases total 1. Hence, the forensic scientists can assume that the number of Adenine base in the DNA is the same as the number of Thymine base.
Answer:
The number of adenine bases will be equal to the number of thymine bases.

The frequency of a wave that has a wavelength of 8 meters is 0. 5 Hz, what is its speed?
The relationship among speed, frequency, and wavelength is
In order for waves to exist, the equation speed(V) = frequency(f) x wavelength() must be obeyed. This equation indicates that the wave's velocity (V) is 4 m/s.
Frequency is defined as the quantity of oscillations of a wave per unit of time, expressed in hertz (Hz). A wavelength is the separation between the two sites that are in phase with one another. As a result, two close wave peaks or troughs are separated by a single full wavelength. Usually, the letter lambda (∧) is used to indicate a wave's wavelength. The wave speed is the distance a wave travels in one unit of time (v). V = f is the formula for wave speed.
given wavelength ∧ =8 m
frequency f = 0.5 Hz
speed V= f∧ = 0.5 x 8 = 4 m/s
the speed of this wave is 4m/s.

the process of exchanging oxygen and carbon dioxide between the alevoli and the blood of the capillaries is called
The process of exchanging oxygen and carbon dioxide between the alveoli and the blood of the capillaries is called gas exchange. This process takes place in the lungs. Oxygen is taken into the body via inhalation and enters the lungs, where it moves across the alveolar walls and into the bloodstream.
At the same time, carbon dioxide, a waste product, moves from the bloodstream across the alveolar walls and is exhaled from the body during exhalation.The lungs are one of the most important organs in the body's respiratory system.
The respiratory system's primary function is to transfer oxygen from the environment to the body's cells while removing carbon dioxide from those cells and returning it to the environment.
The exchange of gases between the atmosphere and the body cells is known as respiration, which occurs in three phases: external respiration, internal respiration, and cellular respiration.

photosynt h. Write short notes on: (i) Pulmonary circulation (ii) Fertilization 11. (ii) Systemic circulation (iv) Vegetative reproducti
Pulmonary Circulation and Systemic Circulation are the types of circulation
1. Pulmonary Circulation:
Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide.
The oxygenated blood then flows back to the heart. Systemic circulation moves blood between the heart and the rest of the body. It sends the oxygenated blood out to cells and returns deoxygenated blood to the heart.
2. Fertilization:
Fertilization is a Reproductive process in which a male sex cell (sperm) unites with a female sex cell (egg). During the process, the chromosomes of the egg and sperm will merge to form a zygote, which will divide to form an embryo.
3. Systemic Circulation:
In the systemic loop, oxygenated blood is pumped from the left ventricle of the heart through the aorta, the largest artery in the body.
The blood moves from the aorta through the systemic arteries, then to arterioles and capillary beds that supply body tissues. Here, oxygen and nutrients are released and carbon dioxide and other waste substances are absorbed.
4. Vegetative reproduction:
Vegetative reproduction is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cuts off the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules.

4. The temperature in \( \# 3 \) is fresh water's temperature of maximum density. a. lower than b. equal to c. higher than
The given statement “The temperature in # 3 is fresh water's temperature of maximum density” means that the temperature at point 3 has a density of maximum density compared to other points of fresh water. So, the temperature at point 3 is equal to fresh water's temperature of maximum density. Therefore, the answer is option b. equal to.
Water is known as the only substance on earth that exists in all three forms, i.e., solid, liquid, and gas. Moreover, the density of water is also unique compared to other substances. Density is the property of a substance that measures the relationship between the mass and volume of a substance. The density of water varies with temperature and pressure. So, the density of water is always higher than that of gases but lower than most solids.
The density of fresh water at standard atmospheric pressure is around 1000 kg/m³, whereas seawater has a density of around 1025 kg/m³ at the surface. The density of water at different temperatures: Water has a unique density-temperature relationship, meaning the density of water varies with temperature.
At 4 °C, fresh water has the highest density, and as the temperature rises or falls below this point, the density of water decreases. So, water has an anomalous density-temperature relationship. Hence, b is the correct option.
