Answer:

B. Waves transfer both matter and energy.

Explanation:

When waves travel through water, the moving water particles continue to return to their starting position because waves transfer both matter and energy.

Answer:

The correct answer is option c.

Explanation:

Conduction of a disturbance from one point to another is termed as a wave. A wave signifies the conduction of energy from one point to another via a material medium. However, a wave may or may not need any form of material medium for conduction. When a wave requires a material medium it is termed as a mechanical wave, while when the wave does not need a material medium for conduction it is termed as electromagnetic waves.  

In the case of mechanical waves, the energy is conducted via the vibration of particles of the medium via which the wave passes. In the case of electromagnetic waves, energy is conducted via the vibration of magnetic or electric fields. Waves perform the role of transmitting energy from one point to another, however, in the process, no movement of matter takes place.

Answer:

Incomplete Dominance

Explanation:

Incomplete dominance is a phenomenon in which the alleles of two genes are not completely dominant over each other and so when they are present at the same time in an organism (heterozygous for that gene) the organism will have an intermediate phenotype that is a combination of both phenotypes.

For example: The flower color in Snapdragon can have three different genotypes as well as phenotypes. The flowers can be red, pink or white depending on their genotype. The allele for red flower (R) is incompletely dominant over allele of white flower (r). A plant with genotype RR will be red flowered and that with rr will be white flowered. However, if a plant has genotype Rr (intermediate), then the flowers will be white in which no allele was dominant over the other and both showed their effect giving a combination of two colors as Pink flowers.

Same is the case with the mating between white and black hen, where offspring was grey in color. This grey was a combination phenotype of two phenotypes.

Answer:to make them more visible

Explanation:

Stains like Methylene Blue are used in microscopy to add color to cells, enhancing the visibility and identification of important cellular structures. It also aids in differentiating and identifying pathogenic bacteria, thereby aiding in disease diagnosis and treatment.

Stains like Methylene Blue are used when observing cells under a microscope because they add color to certain parts of the cells, which otherwise lack contrast and color in their natural state, thus making important cellular structures visible and identifiable. Specifically, the positive chromophores in basic dyes like Methylene Blue latch onto the negatively charged cell walls, making them positive stains, further enhancing the visibility of the cells.

In addition, staining methods can shed light on various aspects of cellular structure and function. For instance, a process like the Gram stain technique uses Methylene Blue as a secondary counterstain, rendering certain non-acid-fast cells blue and allowing pathogenic bacteria to be differentiated and identified. This crucial use of stains enhances the contrast in the microscopic image and helps in the diagnosis and treatment of various diseases.

Water and Carbon dioxide are waste products released as a direct result of cellular respiration. So, the correct option is (D).

Cellular respiration is defined as the process in which organic fuels are oxidized in the presence of an inorganic electron acceptor such as oxygen to produce a large amount of energy to drive the bulk production of ATP.

The function of cellular respiration is that it provides cells with the energy they need to function. If living beings do not get the energy they need from food. All living things will eventually die, regardless of the quality and quantity of food.

In this process, oxygen is released as a byproduct which is used to break down glucose, releasing chemical energy and heat in the process. Carbon dioxide and water are products of this cellular respiration reaction.

Thus, water and Carbon dioxide are waste products released as a direct result of cellular respiration. So, the correct option is (D).

Answer:

External respiration takes place in the lungs

Explanation:

External respiration takes place in the lungs, in the exchange process of carbon dioxide (CO2) and Oxygen (O2). This means that in the lungs, oxygen diffuses into the blood and carbon dioxide diffuses into the alveoli (smallest functional structure of the lungs). In order to understand the difference, in the other hand we have internal respiration which occurs in metabolizing tissues, where the exchange of oxygen and carbon dioxide occurs in the cells.

External respiration is the process by which oxygen is taken in from the environment and carbon dioxide is released from the body. It occurs in the lungs.

During external respiration, oxygen from the inhaled air enters the lungs and diffuses across the thin walls of the alveoli (small air sacs) into the bloodstream.

This process is facilitated by the difference in partial pressure of oxygen between the alveoli and the blood in the pulmonary capillaries. Oxygen binds to hemoglobin in red blood cells and is transported throughout the body.

At the same time, carbon dioxide, which is a waste product produced by cells during cellular respiration, diffuses from the bloodstream into the alveoli. The carbon dioxide is then exhaled out of the body during expiration.

Answer:

Option (c) is the correct answer.

Explanation:

It is known that if we have to convert temperature from kelvin to degree celsius then we have to subtract 273 from the given value of temperature.

Whereas when we have to convert temperature from degree celsius to kelvin then we have to add 273 in the given value of temperature.

Therefore, convert value of 200 Kelvin in the Celsius scale of temperature as follows.

              Temperature = (200 - 273) degree celsius

                                     = - 73 degree celsius

Thus, we can conclude that value of 200 Kelvin in the Celsius scale of temperature is - 73^{o}C.

Answer:

Plant Reproduction and Life Cycle. The life cycle of a plant is very different from the life cycle of an animal. Humans are made entirely of diploid cells (cells with two sets of chromosomes, referred to as ''2n''). ... Plants, however, can live when they are at the stage of having haploid cells or diploid cells.

Explanation:

In an animal life cycle, male and female parents each create sex cells (sperm and eggs) that unite to form a fertilized egg and develop into an offspring organism. Plants, likewise, have sperm and eggs in their life cycles, but these are produced by an intermediate stage between the adult and the offspring.

Humans and ferns are similar as both fertilize to give rise to a new life while different as the haploid form of life present in the ferns life cycle and both male and female reproductive parts are present in one plant.

Therefore, humans and ferns are similar as both fertilize to give rise a new life while different as the haploid form of life present in the ferns life cycle and both male and female reproductive parts are present in one plant.

Answer:

1. Alternation of generations

2. Differentiation

3. Germination

4. Mersitematic cells or Meristem (tissue)

5. Perennial

6. shoots

7. Vascular Cambium

Explanation:

Alternation of generations is a process in the life cycle of a plant and even algae. The alternation part occurs between the sporophyte and gametophyte. A sporophyte is formed when two haploid gametes come together forming a diploid zygote. When the sporophyte matures, it will eventually gain a reproductive organ that would release spores that are haploid spores. These spores become gametophytes. When these gametophytes start to pair up, they become sporophytes. So the cycle begins again.

The meristem is a tissue that is made up of cells called merstematic cells. They produce undifferentiated cells which can specialize into other cells to serve different purposes. Meristems are usually found in areas of the plants that grow.

Perennial means "through the years," and so they are plants that are expected to live a long life, often more than two years. These plants can grow out again from the same roots after they die, so you do not need to replant them.

The growth that starts from the seed that goes in the upwards direction is called shoots, while the growth that goes downwards are called roots. Shoots are the starting point of the growth of the different parts of the plant that are above the ground, like the stem, leaves and the like.

Differentiation is a process where cells start to acquire specific traits to do specific and different functions. Some of the cells that differentiate will not be able to reproduce new ones, some of them die, and the others skip the mitosis stage.

Germination occurs mostly in plants. It is the growth of an organism that starts from a dormant state or a seed.

As plants grow taller, they also grow wider. The vascular Cambium produces undifferentiated cells that form the bark and the woody cells which increases the girth or the wideness of the plant.

Answer:Tides are drive by the gravitational pull off the sun and moon.

Explanation:That is what I got.....

Answer:

Waves are caused by the winds on the surface of the water, while the tides are caused by the force of gravity from the interaction of the moon and the sun on the earth. Gravity, in turn, is a force of nature related to the attraction effects between bodies.

Explanation:

Gravity is a natural force in nature. It is responsible for the forces of attraction that exist between bodies that have mass. It is this force, which allows us to stay attached to the earth. In addition, gravity plays a fundamental role in the existence of tides in the oceans. That's because the tide occurs because of the interaction of the gravitational forces of the moon and the sun on the earth.

The waves, however, occur as a result of the winds that blow over the waters of the ocean.

Answer:

1. A theory is why something happens and a law is how something happens.

Explanation:

Whenever scientists or people studying scientific disciplines face any  scientific question, they try to solve it through proper scientific method. Two of the most important steps of scientific methods are to propose a theory as an answer of the question and after it formulate a law if it can be formed.

In simple terms we can think of a theory as an logical answer that why a certain phenomenon occurs. On the other hand a law is a statement that shows how a phenomenon occurs and it can help in predicting about the phenomenon. Laws are relatively general as compared to theory because theory is logical and well reasoned explanation about a certain happening.

A theory grows into a law when several group of people work on the same question and find same answer in such a way that it is universally approved. Theories can be revised after repeating experiment or condition however scientific law can never be proved wrong and it remains same.

For example: Darwin's theory called Neo- Darwinism in which he said that living organisms can be produced from non-living organism was disapproved by scientists after careful experimentation. It explained the  reasoning that why living organisms can be produced from non-living organisms however if it had been proved by all scientists it would become a law which just explains that how living organisms are produced from non living in a general one or two lines statement. For example: Newton's law of motion.
