_____________________________________REPLICATION---------------------------------------------------------------------------------------------Definition:DNA replication is the process by which a double-stranded molecule of a DNA is replicated(copied) to produce two morphologically and chemically identical DNA molecules.
__________________________________________________Why is it Important:Replication is a very important process for the living organism, because in a cell division, the two new daughter cells are produced which must contain the same genetic information or the DNA just like the parent cell. It cant be less or more than the parent cell.
__________________________________________________Steps of Replication:Replication occurs in three major steps,
1- the opening of the double helix and separation of the DNA strands,
2- the priming of the template strand.
3- the assembly of the new DNA segment.
_____________________________________Best Regards'Borz'DNA is needed to create mRNA.

ABC is an isosceles triangle with AB = BC. If AB = 3x + 41, BC =
8x – 54, and AC = 12x – 103, find x and the measure of each side.
Answer:
x = 90
Explanation:
Ab = 3x + 41, BC = 8x - 54, and AC = 12x - 103, find x and the measure of each side.
-----
AC = AB + BC
------
12x-103 = 3x+41 + 8x-54
---------------------
12x-103 = 11x - 13
x = 103-13
x = 90

What is the memory device for the 3 differences between DNA and RNA?
First of all, the nucleotides of DNA and RNA are different: in DNA, in fact, pentose sugar is deoxyribose, while in RNA it is ribose, which has one more oxygen atom. Moreover, in DNA the nitrogen bases are adenine, cytosine, guanine and thymine while in RNA instead of thymine there is the uracil base
how do the villi and microvilli maximize the ability of the intestine to absorb nutrients?
Answer:The function of the plicae circulares, the villi, and the microvilli is to increase the amount of surface area available for the absorption of nutrients. Each villus transports nutrients to a network of capillaries and fine lymphatic vessels called lacteals close to its surface.

Explanation:
Climate conditions in a small area that differ significantly from the climate of the surrounding area are called
a natural features.
C. biomes.
b. microclimates.
d. ecosystems.
Answer:
b. microclimates.
Explanation:
Microclimates are the climate conditions in a small area that differs significantly from the climate of the surrounding area.
These climatic conditions are usually substantially different from the local climate of an area.
Microclimates can be induced by human activities for example in urban centers with high rise buildings. Also, bodies of water can influence the local climate of an area. Areas with high elevation usually have distinct climatic conditions.Which structure is directly responsible for housing a cell's DNA?

Answer:
Cuando la célula madre se divide varias veces de forma consecutiva y los núcleos se rodean del citoplasma dentro de ella, es una reproducción tipo: esporulación.
Explanation:
En la reproducción asexual, un solo ser origina nuevos individuos iguales entre si e iguales a su progenitor. Este tipo de reproducción es común en ciertos invertebrados, en las bacterias y en los protozoarios. La esporulación es uno de los tipos de reproducción asexual, esta consiste en varias divisiones del núcleo que se envuelve de fragmentos citoplasmáticos, originando muchos descendientes genéricamente idénticos. Dicha reproducción permite la formación de esporas y la liberación de las mismas cuando las paredes de la célula se rompen. Se observa en ciertas especies de protozoarios.

how is the phloem in a leaf related to the roots of the plant?
a. cells that contain sugar move between the leaf and roots within the phloem. 
b. chloroplasts that make sugar move through phloem cells to the roots. 
c. water in the phloem cells comes to the leaf from the roots. 
d. sugar made in the leaf is carried to the roots by cells in the phloem.
Answer:
The phloem carries important sugars, organic compounds, and minerals around a plant. Sap within the phloem simply travels by diffusion between cells and works its way from leaves down to the roots with help from gravity. The phloem is made from cells called 'sieve-tube members' and 'companion cells'.

Explanation:
difference between viruses and cells?
Whilst Virus are non loving infectious particles and need a living host to reproduce.
Answer:
Cells are the basic units of life. Cells can exist by themselves, like bacteria, or as part of a larger organism, like our cells. Viruses are non-living infectious particles, much smaller than a cell, and need a living host to reproduce. The genetic material of the cell is DNA, a double stranded helix.
Another reason is because they can't reproduce by themselves (without a host), viruses are not considered living. Nor do viruses have cells: they're very small, much smaller than the cells of living things, and are basically just packages of nucleic acid and protein.

Answer: # 1: c. #2: d. #3: a
Explanation:
#1 is C. because the equation for cellular respiration is C₆H₁₂O₆
+ 6O2 --> 6H20 + 6CO2 + ATP
This says the reactants (inputs) are oxygen and glucose and the products (outputs) are water, carbon dioxide, and ATP. 1 glucose molecule makes 6 carbon dioxide, so 3 glucose would make 18 carbon dioxide molecules.
#2 is D. because the law of conservation of matter states that matter cannot be created nor destroyed, so the weight before and after cellular respiration would stay the same, as the matter would not change.
#3 is A. because a model would show the exact way the molecules would be arranged, while a formula only tells you how many there are, not the way they would be made up.
