Which compound is inorganic?
O A C6H1206
O B. KH2PO4
OC. CH3COOH
OD. C2H6
O E. C2H5OH

Answers

Answer:

KH2PO4

Explanation:

Organic compounds generally contain carbon and hydrogen.

Inorganic compounds are formed using other elements in the periodic table.

The right response, KH2PO4, is Option B. Since KH2PO4 is an inorganic substance, it doesn't include carbon. Potassium, hydrogen, phosphorus, and oxygen atoms make up the ionic composition. It is a potassium and dihydrogen phosphate anion salt that is used as a food ingredient and fertiliser.

What are organic substances ?

Contrarily, organic substances are those that have carbon and hydrogen atoms in them. The organic molecules C6H1206, CH3COOH, C2H6O, and C2H5OH are a few examples.

These substances differ from inorganic substances in that they include carbon atoms. As KH2PO4 is an inorganic chemical, Option B is the best choice for the right response. Contrarily, organic chemicals are not inorganic since they include carbon atoms.

There are two types of compounds that are organic and inorganic and these both of the molecules are possessing different types of varieties and with that varies as per the compounds and the qualities and with these different types of compounds are made.

(i) What is fertilisation? Distinguish between external fertilisation and internal fertilisation. (ii) What is the site of fertilisation in human beings?​

Answers

♨️ Answer ♨️

i) Fertilisation or fertilization, also known as generative fertilisation, syngamy and impregnation, is the fusion of gametes to give rise to a new individual organism or offspring and initiate its development

What Is Internal Fertilization?

Syngamy of gametes occurs inside the female body after insemination through copulation

Observed in birds, mammals, birds occurring in terrestrial plants and animals, also in some of the aquatic entities. This is observed in three ways – ovoviviparity (eggs retained in the female body, hatched when fully developed, oviparity(egg-laying), viviparity(offsprings develop within the female body)

Observes in plants such as bryophytes, pteridophytes

What Is External Fertilization?

Syngamy of gametes outside the female body/outer environment, notably in water bodies

Observed in few vertebrates, sea urchins, fish, aquatic invertebrates, almost all amphibians

Deposition of sperms and eggs by males and females in open surroundings is known as spawning

Broadcast fertilization – used when sperms swim through the water uniting with eggs to fertilize

ii) In humans, the process of fertilization takes place in the fallopian tube. During this process, semen comprising thousands of sperms are inseminated into the female vagina during coitus. The sperms move towards the uterus and reach the opening of the fallopian tube.

Antibiotics:Medications used specifically against bacteria are called antibiotics.

Difference between bacterial cells and our healthy cells:

Bacterial cells have cell walls. However, Healthy cells of our body lack cell wall.

Why are antibiotics able to target bacterial cells:

Antibiotics are specific in their functions. They are designed as to attack only bacterial cells. They attack the cell wall of the bacterial cell most often. Since, the healthy cells of our body lack cell wall, antibiotics are not able to attack healthy cells of our body.

In this way, our body cells are safe from the attack of antibiotics.

what is dendritic cells and difference between dendritic cells and glial cell

Answers

Answer:

here--->

Explanation:

Dendritic cells (DC) are the professional antigen-presenting cells of the immune system. In their quiescent and mature form, the presentation of self-antigens by DC leads to tolerance; whereas, antigen presentation by mature DC, after stimulation by pathogen-associated molecular patterns, leads to the onset of antigen-specific immunity. DC has been found in many of the major organs in mammals (e.g. skin, heart, lungs, intestines, and spleen), while the brain has long been considered devoid of DC in the absence of neuroinflammation. Consequently, microglia, the resident immune cell of the brain, has been charged with many functional attributes commonly ascribed to DC.

Answers

The number of organisms decreases on movement from producers to consumers in a food chain. This happens due to decreased energy levels at higher trophic levels.

What is a food chain?

Food chain is the sequence of matter and energy transfers as food from one organism to another.

Food chains interconnect locally into a food web as most organisms consume more than one type of animal or plant.

The number of organisms decreases on movement from producers to consumers in a food chain. This happens due to decreased energy levels at higher trophic levels.

How many moles of LiCl are contained in 50.0 mL of 0.600 M solution?

Answers

Answer:

0.0300 moles LiCl

Explanation:

You can find the amount of moles using the molarity formula. The general structure looks like this:

Molar Concentration (M) = moles / volume (L)

You were given the molar concentration and volume in milliliters. Once you convert the volume to liters (by dividing by 1,000), substitute the values into the molarity formula. Then, you can simplify to find moles. The final answer should have 3 sig figs according to the given values.

50 mL / 1,000 = 0.0500 L

0.600 M = moles / 0.0500 L

(0.600 M) x (0.0500 L) = moles

0.0300 = moles
