Answer:
In compare to eukaryotes,prokaryotes are morphologically simpler,more evolutionary primitive,less sensitive to physical environment.
Explanation:
Prokaryotes are unicellular organism which don't possess cell organelle like nucleus,mitochondria,Endoplasmic reticulum,golgi body, etc.
They are the first living organism in the primitive earth and the genetic components are located in the cytoplasm which is enclosed by cell membrane.
prokaryotes contain 3 domains that are Archaea, bacteria and eukarya.
The cytoplasm is enclosed by cell membrane.
Molecular studies have reveal that eukaryotes are evolved from prokaryotes.
Some prokaryotes bear long projection which helps them for locomotion,called as flagellum.This is present in gram positive and gram negative bacteria.
Answer:
Explanation:
The tricuspid valve separates the right atrium from the right ventricle carrying deoxygenated blood from right atrium to right ventricle
The mitral/bicuspid valve separates the left atrium from the left ventricle carrying oxygenated blood from left atrium to left ventricle
Pulmonary semilunar valves separates the right ventricle from the pulmonary artery preventing bachelor of blood.
Aortic semilunar valves separates the left ventricle from the aorta preventing backflow of blood
Answer:
<h2>b) Anaphase II of meiosis
</h2>
Explanation:
1. Meiosis is the process of cell division in which one cell is divided into four daughter cell, each contains equal number of chromosome, half the number of chromosomes as compared to parental cell.
2. In meiosis I, DNA duplication occurs but the sister chromatids are not separated, only homologous pair of chromosomes are separated, so this is called reductional division.
3. In meiosis II, chromatids are pulled apart and and are separated into different chromosomes, so it is called equational division. There is no DNA duplication in meiosis II.
Answer:
The two types of lipoproteins are low density lipoprotein and high density lipoproteins
Explanation: As applying to low density lipoproteins (LDL), these are sometimes called the bad cholesterol because a high LDL level leads to a build up of cholesterol in the arteries. This condition narrows the arteries and increases the risk of heart attack, Strom and peripheral artery diseases.
High Density Lipoproteins (HDL), also known as the good cholesterol acts as a scavenger carrying LDL away from the arteries and back to the liver where the LDL is break down and passed from the body.
<h2>Lymphatic System</h2>
Explanation:
- The <u>Blood pressure</u> in the capillaries drives the filtration of water and small molecules from the blood into the <u>interstitial space </u>of the tissues.
- The invulnerable system is the mind boggling assortment of cells and organs that annihilates or kills pathogens that would somehow cause malady or passing.
- The lymphatic system, for a great many people, is related with the safe system to such an extent, that the <em>two system are for all intents and purposes undefined. </em>
- The lymphatic system is the arrangement of <em>vessels, cells, and organs</em> that conveys abundance liquids to the <em>circulatory system and channels pathogens from the blood.</em>
- The growing of lymph hubs during a contamination and the vehicle of lymphocytes by means of the<em> lymphatic vessels are nevertheless</em> two instances of the numerous associations between these basic organ system.
- Circulatory strain <em>causes spillage of liquid from the vessels, bringing</em> about the aggregation of liquid in the interstitial space that is, spaces between singular cells in the tissues.
- In people, 20 liters of plasma is discharged into the interstitial space of the tissues every day because of slender filtration.
- Lymph is the term used to portray interstitial liquid once it has entered <em>the lymphatic system.</em>
