what did Galileo contribute to the field of microscopy

Answers

Answer 1

Answer:

In the late 16th century several Dutch lens makers designed devices that magnified objects, but in 1609 Galileo Galilei perfected the first device known as a microscope. Dutch spectacle makers Zaccharias Janssen and Hans Lipperhey are noted as the first men to develop the concept of the compound microscope.

The energy of the reactant is lower and the energy of the product is higher in this kind of reaction, it is called an endothermic reaction.

What is an endothermic reaction?

A thermodynamic process in which energy is absorbed is called an endothermic reaction. In this kind of reaction, when heat is given during the reaction, is absorbed by the reactant to form the product. It takes heat from its surrounding.

Some examples of endothermic reactions are:

The melting of ice to form water is an endothermic reaction.When nitrogen and oxygen react with each other to form nitric oxide, it absorbs energy.When ammonium chloride (NH₄Cl) reacts with water (H₂O), it absorbs heat.

Hence, the correct sequence is:

The lower energy of reactant → transition state → higher energy of the product.

Enlist the features of cell membrane.​

Answers

Answer:

It is the outermost covering of a cell that separates the contents of the cell from its external environment.

It only allows the entry and exit of some materials. It also prevents the movement of some. Therefore, it is also called a selectively permeable membrane.

Some substances like carbon dioxide and oxygen can move across the cell membrane due to the process known as diffusion.

Water also obeys the laws of diffusion. The movement of water molecules through a selectively permeable membrane is called osmosis.

Children inherit half of their genes from parents. Explain Why?

Answers

Answer:

This is because the two parents share one or more common ancestors and so carry some of the same genetic material. If both partners carry the same inherited gene change, their children are more likely to have a genetic condition.

Answer:

yes

Explanation:

The chromosomes in cells line up in pairs and exchange bits of genetic material before forming an egg or sperm cell. Each mature egg and sperm then has its own specific combination of genes, which means children will inherit a slightly different set of DNA from each parent.

A.Replication involves copying a whole molecule to produce a double-stranded molecule of DNA. RNA is a single stranded and is transcribed from a portion of one strand of DNA to produce a protein

B. Replication involves copying a whole molecule to produce a double-stranded molecule of RNA. DNA is a single stranded and if transcribed from a portion of one strand of RNA to produce a protein

D. Replication involves copying a portion of one strand to produce a single-stranded molecule of DNA. RNA is double stranded and is produced by transcribing a whole molecule of DNA to produce a protein.

Answers

Answer:

A.Replication involves copying a whole molecule to produce a double-stranded molecule of DNA. RNA is a single stranded and is transcribed from a portion of one strand of DNA to produce a protein

Replication involves copying a whole molecule to produce a double-stranded molecule of DNA. RNA is a single stranded and is transcribed from a portion of one strand of DNA to produce a protein.

What is Replication?

A double-stranded DNA molecule is copied to create two identical DNA molecules through the process of DNA replication. Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.

The ability of each DNA strand to function as a template for duplication is essential to the replication process. DNA double helix unwinding occurs at specified locations, known as origins, where DNA replication begins.

The production of a primer, a brief section of RNA that serves as the beginning point for the synthesis of fresh DNA, follows. The DNA is then replicated by a protein called DNA polymerase by matching bases to the original strand.

Therefore, Replication involves copying a whole molecule to produce a double-stranded molecule of DNA. RNA is a single stranded and is transcribed from a portion of one strand of DNA to produce a protein.
