Who was Albert Einstien and what was he known for ?

Here ya go , Fivez and marcus UwU

Answers

Answer:

Albert Einstein is a German-born physicist and scientist who has created many ideas and theories relating to the study of relative. He is famously known for creating the famous equation [tex]e = mc^{2}[/tex] (Energy equals mass times the speed of light squared).

He was involved in the help of creating nuclear powered- mechanisms (not for destroying things, but for helpful, everyday things). Matter has an inherent amount of energy to it, mass can be converted (under the right conditions) to pure energy, and energy can be used to create massive objects that did not exist previously. Nuclear fission takes place when a heavy atomic nucleus, such as uranium, breaks into two or more smaller pieces with the release of some energy. During this process some of the mass of the original atom is converted into energy in accordance with the equation [tex]e = mc^{2}[/tex].

A multicellular organism begins life as a single cell-a fertilized egg with a
complete set of chromosomes. The picture in Figure 10-2 above shows how the
cell divides to become two cells, then four cells, eight cells, and so on. Which of
the following statements best describes what happens during this process?

Answers

Answer options:

a.) chromosomes are duplicated before cell division so that each new daughter cell has a complete set.

b.) chromosomes are divided evenly during cell division so that each new daughter cell has an equal share of the original set.

c.) chromosomes are stored in the original cell to direct the division of all daughter cells, which do not have their own chromosomes.

d.) chromosomes are randomly distributed during cell division so that some new cells have partial sets while others have complete sets.

Answer:

a.) chromosomes are duplicated before cell division so that each new daughter cell has a complete set.

Explanation:

The cell divisions that allow organisms to grow are called mitosis. Before mitosis, all the DNA is duplicated.

Then, during mitosis, it condenses to form chromosomes. The identical chromosomes align in the centre of the cell. Then, they are equally distributed to among two daughter cells.

These two daughter cells each have a complete set of chromosomes. Each  daughter cell identical to the parent cell and to the other daughter cell.

The statement (D) is correct. DNA has thymine and RNA has uracil.

What is DNA and RNA?

DNA and RNA are both types of nucleic acids, large molecules that are made up of monomers called nucleotides. Nucleic acids are used to store genetic information, which the cell uses to make proteins.

Moreover, nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on to the next generation.

Hence, DNA is a double-stranded molecule that has a long chain of nucleotides. RNA is a single-stranded molecule which has a shorter chain of nucleotides. DNA replicates on its own, it is self-replicating. RNA does not replicate on its own.

Option D

Explanation:

The well defined nucleus is absent in prokaryotes whereas the well defined nucleus covered with nuclear envelope is present in eukaryotes. The site of replication and transcription is the nucleus in the living organism.

The nucleus contains the double membrane structure. Outer membrane and inner membrane covers the nucleus. Nucleus also contains the nuclear pore through which molecules can move inside and outside of the nucleus and the cytoplasm.

Does the plant use all wavelengths of light to carry out photosynthesis? Why does this make plants look green?

Answers

Answer:

Chlorophyll, the green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects. ... All photosynthetic organisms have chlorophyll a which absorbs violet-blue and reddish orange-red wavelengths. Chlorophyll a reflects green and yellow-green wavelengths. Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs.
