Answer:

Scientific Theory

Explanation:

The statement "the characteristics of living things change over time" refers to the concept of biological evolution, which is widely accepted as a scientific theory in the field of biology. In scientific terms, a theory is a well-substantiated explanation of a natural phenomenon that is supported by extensive evidence, experimentation, and scientific consensus. The theory of evolution, proposed by Charles Darwin and further developed over time, provides a comprehensive explanation for the diversity and change in the characteristics of living organisms. It is supported by a vast body of evidence from various scientific disciplines, including genetics, paleontology, comparative anatomy, and molecular biology.

In contrast, scientific laws describe observable patterns or regularities in nature that are often expressed as mathematical equations or principles. Laws, such as Newton's laws of motion or the laws of thermodynamics, describe specific relationships or behaviors in the physical world.

Therefore, the statement about the characteristics of living things changing over time aligns with the theory of evolution, rather than being described by a scientific law.

Explanation:

Respiration is the type of biological exercise that raises Co₂ concentration in the atmosphere.

Explanation:

RESPIRATION is said to be the basic biological and metabolic process that is essential for all living beings for their survival and growth with nourishment.

Cells are the basic unit of living organisms that undergo cellular respiration. In this process, oxygen is in taken and carbon dioxide is respired out which adds the concentration of the carbon dioxide from the atmosphere.

In the process of respiration, the living cells of the organism produce energy by the intake of oxygen for the oxidation of complex organic substances and expires out the carbon dioxide.

As we know the cellular cycle is composed of four main stages, G1 a growing phase, S a synthesis phase, G2 preparation for division, and M mitosis the actual division process. So the order is as follows:

A: Interphase

B: Phase S

C: G1 phase

D: G2 phase

Explanation:

The correct combination of vital signs is temperature, respiratory rate, and heart rate.

Vital signs are key measurements that provide important indicators of a person's physiological status and overall health. They help healthcare professionals assess and monitor a patient's condition. The vital signs typically include temperature, respiratory rate, heart rate, and blood pressure. Among the options provided, the correct combination of vital signs is temperature, respiratory rate, and heart rate.

Temperature is a measure of the body's internal heat. It can be measured orally, rectally, or with the help of infrared thermometers. Deviations from the normal range may indicate fever or hypothermia, which can be indicative of underlying health issues.

The respiratory rate refers to the number of breaths a person takes per minute. It provides insight into lung function and overall respiratory health. Abnormal respiratory rates may suggest respiratory distress or underlying pulmonary conditions.

Heart rate, also known as pulse rate, measures the number of times the heart beats per minute. It reflects cardiac activity and can be assessed by feeling the pulse at various points in the body. Deviations from the normal heart rate can indicate cardiovascular problems or other physiological abnormalities.

Weight, muscle mass, and height are not typically considered vital signs. They are important anthropometric measurements used for assessing overall body composition, growth, and nutritional status. While these measurements are relevant in healthcare, they are not classified as vital signs.

In summary, the vital signs include temperature, respiratory rate, and heart rate. Monitoring these parameters allows healthcare professionals to gain valuable insights into a patient's health status, identify potential issues, and make informed decisions regarding treatment and care.

Photosynthesis is divided into 2 phases: light phase or light-dependent and dark phase or light-independent.

The light phase is so called because the energy of the photons of sunlight is captured in this phase. This energy is transferred to the electrons of the plant which are previously provided by water molecules.

When water gives up its electrons in the thylakoid, H+ is released for energy production, and O2 molecules are released through the stomata during the light phase.

Itching and other skin problems are signs that a cat or dog may have flea. Fleas are parasites known for their biting and blood-sucking abilities. When they bite, flea saliva enters the pet’s circulatory system, sometimes causing an allergic response commonly seen as a “hot spot” on the pet’s neck or the base of its tail.

Fleas are tiny parasitic insects that infest the fur of dogs and cats. They feed on blood and cause skin irritation that results in itching. If the problem is severe, it can lead to more significant health issues. Pet owners should watch for signs of fleas and treat their pets promptly to avoid complications. Fleas lay eggs on the skin of dogs and cats, which hatch and develop into larvae.

The larvae feed on the skin, shedding as they mature. Adult fleas emerge from the larvae, biting the host to feed on blood. The process repeats itself, with adult fleas continuing to lay eggs on the skin of the pet.The most common sign of fleas in dogs and cats is itching. Pets will often scratch themselves, bite their skin, or lick excessively to relieve the irritation.

Other signs of fleas include red or inflamed skin, hair loss, and the appearance of small, raised bumps on the skin. These bumps are often referred to as "flea dirt" and are the waste products of the fleas. In severe cases, anemia, an allergic reaction, or the transmission of other parasites or diseases can occur.

Flea infestations can be treated with a variety of products, including topical treatments, shampoos, and collars. It is essential to follow the instructions on the product label and treat the pet and the surrounding environment to eliminate the fleas. Prevention is key to avoiding flea infestations, so pet owners should maintain a regular grooming and flea prevention schedule.

Phagocytes are a type of immune cells that specialize in engulfing and digesting foreign particles, such as bacteria, viruses, and cellular debris. The two phagocytes are Neutrophils and Macrophages.

Neutrophils are a type of white blood cell and are the most abundant phagocytes in the bloodstream. They are quick to respond to infections and are often the first immune cells to arrive at the site of an infection. Neutrophils engulf and destroy pathogens by a process called phagocytosis.

Macrophages are a type of white blood cell that is present in various tissues and organs of the body. They are highly specialized phagocytes and play a crucial role in engulfing and eliminating foreign substances. Macrophages not only participate in immune responses but also contribute to tissue repair and maintenance.

Answer: The genotype of a ladybug with 10 spots is AABBCCDDEE.

Explanation: We know that the number of spots on a ladybug’s carapace is determined by polygenes. A ladybug with no spots has the genotype aabbccddee, while a ladybug with 20 spots has the genotype AABBCCDDEE. This means that each dominant allele adds 2 spots to the carapace.

Since a ladybug with 10 spots has half as many spots as a ladybug with 20 spots, we know that it has half as many dominant alleles. This means that it has one dominant allele for each gene.

To determine the genotype of a ladybug with 10 spots, we can use the following steps:

Start with the genotype for a ladybug with no spots: aabbccddee

Add one dominant allele for each gene to represent the 10 spots: AaBbCcDdEe

The genotype of a ladybug with 10 spots is AABBCCDDEE.

Answer:

O As the air around the campfire is heated and becomes less dense, it rises and moves upward.

Explanation:

This is true because, the convection transfer needs the particle of elements to transport the heat from where it is in abundance to where it is in less abundance. Just like a water boiling becoming hot at the point closer to the fire than the top of the pot, so also will the air around campfire transfer heated air from the place closer to the campfire to upwards aware from the fire.

Convection is the flow of air around the campfire when it is heated and the decrease in density as it rises upward in the atmosphere. Thus, the correct option is C.

Convection is the transfer of heat from one place to the other due to the movement of fluids present in it. It is a distinct method of heat transfer in systems. The convective heat transfer involves combined processes of conduction and advection in a system and its surrounding. Convection is the dominant form of heat transfer in liquids and gases.

The thermal radiation in the fire is mostly in the form of infrared waves and visible light. However, the campfire heat transferred via convection shoots straight up in the sky and never reaches to the ground level.

Therefore, the correct option is C.
