Answer:
Lymphatic: bacteria invade the body but are removed with the help of cells
Endocrine: A chemical message is signaled to help the body relax and sleep
Nervous: The brain signals for the muscles to contract
Explanation:
Lymphatic system is the part in the body that uses the cells in your body to help it.
The endocrine system is about hormones and how the body needs to maintain stable and have homeostasis.
The brain is part of the nervous system and it sends signals to other parts of the body.
Answer:
I conclude that the answer is B
Answer: Haploid number
In normal humans, sex cells contain the diploid number of chromosomes
Explanation;
Human somatic cells or body cells are diploid such that they contain two sets of 23 chromosomes which gives a total of 23 chromosomes. Examples of somatic cells in the body that are diploid include, epithelial cells, somatic cells, liver cells, blood cells, nerve cells, etc.
However, mature sex cells are haploid, which means they have one set of 23 chromosomes which means they have 23 chromosomes. Sex cells are the results of meiosis type of cell division in which a diploid cell divides to form four daughter cells that are haploid.
Answer:
first is mRNA and second is amino acid
Explanation:
There are three ways heat is transferred into and through the atmosphere.
radiation. conduction. convection.
Radiation
Radiation is the transfer of heat energy through space by electromagnetic radiation.If you have stood in front of a fireplace or near a campfire, you have felt the heat transfer known as radiation. The side of your body nearest the fire warms, while your other side remains unaffected by the heat. Although you are surrounded by air, the air has nothing to do with this transfer of heat. Heat lamps, that keep food warm, work in the same way.
Conduction
Welding iron is transferring heat by conduction
Conduction is the transfer of heat energy from one substance to another or within a substance. Have you ever left a metal spoon in a pot of soup being heated on a stove? After a short time, the handle of the spoon will become hot.This is due to transfer of heat energy from molecule to molecule or from atom to atom. Also, when objects are welded together, the metal becomes hot (the orange-red glow) by the transfer of heat from an arc.
Convection
convection is the transfer of heat energy in a fluid. This type of heating is most commonly seen in the kitchen with a boiling liquid.
Air in the atmosphere acts as a fluid. The sun's radiation strikes the ground, thus warming the rocks. As the rock's temperature rises due to conduction, heat energy is released into the atmosphere, forming a bubble of air which is warmer than the surrounding air. This bubble of air rises into the atmosphere. As it rises, the bubble cools with the heat contained in the bubble moving into the atmosphere
