Answer:
In CONVECTION, heat energy is carried by the movement of particles of matter. In CONDUCTION, heat is transferred by particles vibrating. In RADIATION, heat is carried directly by electromagnetic waves. When a hot object touches a cool object, heat moves from the hot one to the cool one.
Explanation:
Movement of heat by a fluid such as air is carried out by convection and through electromagnetic via radiation.
What is convection and radiation?Heat is transferred by a fluid, such as water or air, by convection. As the fluid (liquid or gas) flows from one place to another, it also transfers heat. A current is the term used to describe the flow of heated water or air.
Radiation occurs when heat transfers directly from one source to another object as infrared energy waves. This is how the Sun's heat reaches Earth. In actuality, all heated objects emit heat toward colder objects. The molecules of the colder item accelerate as the heat waves impact them. The thing becomes hotter as its molecules move more quickly.

Where is tRNA mRNA and DNA
found in the cell
Answer:
Cytoplasmic tRNAs are found in the fluid inside cells (the cytoplasm). These tRNAs help produce proteins from genes located in the DNA in the nucleus of the cell (nuclear DNA). Although most DNA is nuclear, cellular structures called mitochondria have a small amount of their own DNA, called mitochondrial DNA. and mRNA is found in the nucleus and the cytoplasm in cells.
Explanation:
hope it helps : )
tRNA (transfer RNA) and mRNA (messenger RNA) is found in the cytoplasm of the cell. DNA (deoxyribonucleic acid) is found in the nucleus of the cell.
tRNA plays a crucial role in translating the genetic information carried by mRNA into specific sequences of amino acids during protein synthesis. tRNA molecules are involved in bringing the correct amino acids to the ribosome based on the codons present in the mRNA.
mRNA is synthesized from DNA in the nucleus during a process called transcription. Once produced, mRNA leaves the nucleus and moves into the cytoplasm, where it serves as a template for protein synthesis. In the cytoplasm, mRNA is associated with ribosomes, which are the sites of protein synthesis.
DNA is primarily found in the cell nucleus, where it stores the genetic information of an organism. In some cases, a small amount of DNA can also be found in organelles called mitochondria (in eukaryotic cells) and plastids (in plant cells).

Blood plays an important role in thermoregulation. Which of the following statements
about thermoregulation is NOT correct
A. Thermoregulation involves a balance between the production of heat and
the loss of heat.
B. The rate of heat loss is affected by the difference between temperature
of skin and external environment.
C. Internal conditions remain the same regardless of the external
conditions.
D. Heat loss from surface of the body is slower when the temperature
difference is higher.
E. Heat loss from the body deceases as more blood passes through the
skin.
Answer: C and E options not correct.
Explanation:
Thermoregulation itself is actually a branch of homeostasis. Homeostasis is defined as the internal regulation of body environment which includes the vital organs of the body such as the heart, liver, brain and contraction of skeletal muscles.
However, there are four routes of heat lost in the body. They are through convection, conduction, radiation, and evaporation. If skin temperature is greater than that of the surroundings, the body can lose heat by radiation and conduction. But, if the temperature of the surroundings is greater than that of the skin, the body actually gains heat by radiation and conduction. In such conditions, the only means by which the body can rid itself of heat is by evaporation. So, when the surrounding temperature is higher than the skin temperature, anything that prevents adequate evaporation will cause the internal body temperature to rise. Even during sports activities, evaporation becomes the main avenue of heat loss. Humidity itself, affects thermoregulation by limiting sweat evaporation and thus heat loss.

Explain why coloured water moved up the stalks
Answer:
water molecules like to stick together (cohesion) and like to stick to the walls of the tubes of cellulose (adhesion
Explanation:
water moves from roots to leaves. ... Because water molecules like to stick together (cohesion) and like to stick to the walls of the tubes of cellulose (adhesion), they rise up the tubes all the way from the roots to the leaves.
Water molecules prefer to attach together and to the sidewalls of the cellulose tubes via which water travels from roots to the leaves.
Water molecules in plants:Water molecules ascend up the tubes from the roots of plants because they like to adhere together (cohesion) and attach to the walls of the cellulose tubes (adhesion).
Capillary motion is what we term when water travels into small gaps like that. Because the water particles bonded to the coloring and carried it along, the color in the water travelled up into the celery with both the water in this process. Water going into a plant in nature brings nutrients from the earth with it.
