Answer and explanation :
we need energy because without energy we can not do any thing energy is necessary for doing any work as like petrol or diesel for driving our vehicles as like we need energy for doing any physical or mental work energy is the fuel of our body without it we can not do anything. It fuels the body internal function repair and build the cells and support the external activities that help our body to do any work
This active transport mechanism is a sodium-potassium pump.
The sodium potassium pump is a sequence of proteins within the cell membrane. It moves sodium and potassium ions across the cell membrane in a process called facilitated diffusion, or active transport: when ions move against the concentration gradient, or to a highly concentrated region. To do so, the pump needs energy in the form of ATP, which is produced through cellular respiration. Once the pump receives this energy, it is able to maintain the resting potential in a nerve cell.
The process of homeostasis is retained at a cellular level by making the cell get rid of waste materials such as carbon dioxide. Carbon dioxide is produced in cellular respiration. Other waste materials are utilized to make oxygen and protein.
Answer:
Asexual is reproduction with one parent (single celled organisms)
Sexual is reproduction with two parents
Explanation:
<h2>
<u>Asexual reproduction</u> </h2>
is a type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it does not involve the fusion of gametes and almost never changes the number of chromosomes. Asexual reproduction is the primary form of reproduction for single-celled organisms such as the archaebacteria, eubacteria, and protists.
<h2>
<u>Sexual Reproduction</u></h2>
Sexual reproduction is a form of reproduction where two morphologically distinct types of specialized reproductive cells called gametes fuse together, involving a female's large ovum (or egg) and a male's smaller sperm. Each gamete contains half the number of chromosomes of normal cells.
