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

Write a statement about the role gravity plays in the motion of the planets.
Answer:
Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. ... Gravity creates stars and planets by pulling together the material from which they are made. Gravity not only pulls on mass but also on light.
If temperature remains the same and pressure goes up, volume goes (up or down)

. 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:
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.

An allele that occurs in the gametes of an organism will most likely be transferred to which of the following?
O The offspring of the organism
O The mating partner of the organism
The siblings of the organism
O The other organisms living nearby
NEED HELP ASAP !!!! Thank you
Answer:
The offspring of the organism
Explanation:
The alleles of two mature gametes swap and mix during the reproduction process. Allowing for expression of certain more dominant or recessive traits in an offspring. An offspring contains a mix of allele say Aa from aa, AA parents alleles.
The human genome project was produced an area of science known as bioinformatics. how is this helpful in sequencing DNA?
Bioinformatics is a subdiscipline of biology/computer science concerned with the acquisition, storage, analysis, and dissemination of biological data. This helps organize and determine nucleotides of a given DNA molecule from known data about biological data through computer sustems.
** The Human Genome Project increased speed of DNA sequencing and lowered the cost. Basically made it more efficent.
Check out Bioinformatics lectures and websites! You will gain a better understanding of how this is helpful for sequencing DNA.
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

Large areas around the globe with similar climates and similar communities of organisms form
a
a population.
b
a biome.
c
an ecosystem.
d
a species.
Answer:
c
Explanation:
Answer:
a biome
Explanation:
a species is a type of animal kind, a population is the number of a certain species, an ecosystem is basically a big web of nature that is connected. so we can rule those 3 out. a biome is a part of land with similar climates and organism population
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.2.) Interphase includes what "3" things. Check all 3.
*
A. Growth
B. DNA copied
C. Sister chromatins pulled apart
D. Preparing to divide
E. cytokinesis
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.

what is the function of the Diaphragm
Answer: It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs. The diaphragm, located below the lungs, is the major muscle of respiration. It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges.

Explanation:
Simple organic molecules combine to make larger molecules. Which statement best describes the disruption of the bond between two carbohydrate monomers? (3 points) Dehydration synthesis will remove water molecules, forcing the bond to break. Energy will be stored in the bond between monomers through hydrolysis. The bond in the complex carbohydrate will be broken due to enzyme activity. The helium and hydrogen atoms in the backbone of the sugar will be broken.
Answer:
The correct answer is - The bond in the complex carbohydrate will be broken due to enzyme activity
Explanation:
Carbohydrates are macromolecules formed by the combined simple monomer subunits to make a larger subunit or chain of molecules. Dehydration synthesis is the process required for the build-up of these larger molecules and for this they require energy.
The hydrolysis reaction is used to break the hydrogen bond of these monomer backbones by the addition of water which releases energy. Complex carbohydrates are digested or the bonds present in between their monomers are broken down due to the activity of the series of the enzymatic reaction.
Answer: The bond in the complex carbohydrate will be broken due to enzyme activity.
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.
