Which element has the least neutrons in the nucleus?
Aluminum
Nitrogen
Helium
Fluorine
Answer:heh
Explanation:
Aluminium , mass no = no of proton + neutron = 27
atomic no = no of proton = 13
no of neutron = 27 - 13 = 14
Nitrogen , mass no = no of proton + neutron = 14
atomic no = no of proton = 7
no of neutron = 14 - 7 = 7
Helium , mass no = no of proton + neutron = 4
atomic no = no of proton = 2
no of neutron = 4 - 2= 2
fluorine , mass no = no of proton + neutron = 19
atomic no = no of proton = 9
no of neutron = 19-9 = 10
Answer:
helium
Explanation:
i took the test and got it right... it also has the smallest number

Identical, or monozygotic, twins develop from a single egg fertilized by a single sperm. Monozygotic twins are genetically identical because they originate from a single zygote that split into two. Caroline Lost and her colleagues examined nine measures of social, behavioral, and cognitive ability in 1000 pairs of both male and female identical twins. Their study found that pairs of male twins tended to be more alike in their prosocial behavior, peer problems, and verbal ability scores than pairs of female twins. Which statement explains this observation?
Answer:
Female mammals undergo X-chromosome inactivation during early embryogenesis, thereby females are mosaic for the expression of X-linked genes
Explanation:
In mammals, males receive only one copy of the X chromosome and one Y chromosome, while females receive two copies of the X chromosome. The X chromosome contains approximately 1,000 key genes involved in development. In human female embryos, one of these two copies of the X chromosome is inactivated to prevent the imbalance caused by a double dose of X-linked genes, a phenomenon known as X-chromosome inactivation. The inactivation of one X-chromosome is a random process, thereby female cells are mosaics for all heterozygous X-linked alleles, where some embryonic cells have an inactive maternal X chromosome, while other cells have an inactive paternal X chromosome.
How many molecules of water are created when making a lipid?
Answer:
Three molecules
Explanation:
Since fats consist of three fatty acids and a glycerol, they are also called triacyclglycerols or triglycerides. Triacyclglycerols: Triacylglycerol is formed by the joining of three fatty acids to a glycerol backbone in a dehydration reaction. Three molecules of water are released in the process.
Answer: 3 molecules

Collect data: Blood carries many vital substances. Four of these are listed above the Microscopic view. Oxygen and sugar are needed by all body cells. Carbon dioxide and urea are waste products. What are the concentrations of each substance in this sample?
Oxygen:
Carbon Dioxide:
Sugar:
Urea:
Answer:
Explanation:
in the given sample of blood concentration of all the comonents is normal. the concentration of urea is 2.6 to 6.5 mM, concentration of carbon dioxide is 23-29 meq/L, while concentration of glucose ad oxygen are 0.9 g and 20.1 ml respectively.
Blood is the component of the circulatory system which is essential for the transport of gases and excretion of waste products. It is crucial for nutrient and oxygen supply to the body.
The concentration of oxygen was 95.6 mmHg, carbon dioxide 39.3 mmHg, Sugar 115.5 mg and urea 13 mg.
The vital substance of blood can be explained as:Red blood cells are called erythrocytes that are responsible for oxygen transportation through the hemoglobin component to the body parts while on their way back it carries the carbon dioxide.Sugar is the major form of energy needed by the body for functioning which enters the blood from the liver.Urea is the waste complement removed with the help of blood collected from the liver and excreted by kidneys.Therefore, the normal concentration of blood substances is oxygen 95.6 mmHg, carbon dioxide 39.3 mmHg, Sugar 115.5 mg and urea 13 mg.

Answer:
1. Receptor (nociceptor).
2. Afferent neurons.
3. Spinal cord.
4. Motor neurons.
5. Efferent neuron (effector).
Explanation:
In Biology, stimulus can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.
In this scenario, you accidentally stub your toe on a chair when walking in a darkened room. A receptor (nociceptor) relays this information by sensory nerves in the afferent neurons to the spinal cord, which in this case is the spinal cord. You immediately step back because the spinal cord sends a command via the motor neurons to your leg muscles, which are acting as the efferent neuron (effector).

Compare the reactants and products in the chemical equations below. Which statement best describes the relation between matter and energy?
Answer and Explanation:
Chemical reactions are very complex processes which include the collision of molecules. During the chemical reactions, bonds between the breakdown of the atom and transformed in new ways. The chemical compounds that react together during the chemical reactions are called reactants, shown on the left side of the equation. They are broken down during the reaction and used as the reaction progresses. The chemical compounds that are formed from the rearrangement and breakdown of the reactants are called products. The products are shown on the right side of the chemical equation. As compare to the reactants, the products are more stable molecules. For example, in the reaction between H2SO4 and Zn, these two chemicals are the reactants, while ZnSO4 and H2 are the chemical reaction products.
Zn + H2SO4 ZnSO4 + H2
(Reactants) (Products)
The matter is a material that everything is made of matter. A property that matter has is known as energy. The same quantity of matter can have a diverse quantity of energy. Both energy and matter are identical. For example, if we add some energy into an ice cube, it will turn into liquid. After that, if we add more energy, liquid will turns into steam.
