why is DNA replication called simi conservative
Answer:
As the DNA double helix is unwound by helicase, replication occurs separately on each template strand in antiparallel directions. This process is known as semi-conservative replication because two copies of the original DNA molecule are produced. Each copy contains one original strand and one newly-synthesized strand.

Which one of these situations would have higher density water?
Question options:
Water at the equator
Lower temperature water
Water with a lower salt content
Water near where a river enters the ocean
A higher density water will be obtained in lower temperature water.
What is density?Density is the fluid property that describes the amount of solutes that dissolves in a given volume of the fluid.
Density of a fluid is calculated by taking the ratio of mass to volume of the fluid.
[tex]\rho = \frac{m}{v}[/tex]
where;
m is the mass of the waterv is the volume of the waterWhen the temperature of the water is low, more mass of the water is obtained while a high temperature evaporates the liquid.
Thus, a higher density water will be obtained in lower temperature water.

The diagram below illustrates a natural Earth process through which the atmosphere
traps heat. Many scientists hypothesize that human activities are accelerating this
process, resulting in a global warming trend. What human activity is believed to have an
adverse effect on the natural process pictured here?
Answer: c. burning of fossil fuels.
Explanation:
Carbon Dioxide and other greenhouse gases like it are the reason some of the sun's heat is trapped in the atmosphere instead of leaving back into space. Any process which increase the amount of carbon dioxide in the atmosphere therefore can increase global warming.
One of the major human activities that involves releasing carbon dioxide is the burning of fossil fuels. We use fossil fuels for many things including producing electricity and driving. When this happens we release a lot of carbon dioxide into the atmosphere thereby making global warming worse.

Answer:
Nondisjunction (during meiosis in gametogenesis)
Explanation:
This is meiosis because we can see germ cells present, and the chromosome number is halved (typically) by the end of the process. This is nondisjunction because the sister chromatids/chromosomes are failing to separate properly during cytokinesis, causing improper amount of chromosomes in the germ cells. So on the left you have nondisjunction during meiosis II, because you have two cells with the proper amount of chromosomes after the first division. And on the right you have nondisjunction during meiosis I, because you have one cell with no chromosomes after the first division. The steps are as follows: 1 - Meiosis, 2 - Meiosis II, 3 - Fertilization, and 4 - Zygote (creation of).

Sedimentary rocks can be made of particles from which of the following?
-Sedimentary
-Metamorphic
-Igneous

All of the above.
Sedimentary elements are made up of broken down particles from many different substances. Sedimentary rock forms when multiple particles lump together to make a larger particle until it becomes highly visible and large. For example,
The Mississippi River carries sediment from upstream (typically soil from the dryer parts of the USA) and that sediment gathers into levee's which help protect the coast of Louisiana and the Gulf of Mexico.

How are photosynthesis and cellular respiration related?
A. The products of photosynthesis are the reactants of cellular
respiration
B. Cellular respiration is the process animals use to produce glucose,
while photosynthesis is the process plants use to produce
glucose.
C. Photosynthesis produces water molecules, while cellular
respiration splits water molecules apart.
D. Cellular respiration provides the energy for photosynthesis.
Answer:
I would say your answer for this question would be Option D: Cellular respiration provides the energy for photosynthesis.
Explanation:
Photosynthesis is the process by which plants use the energy from sunlight, carbon dioxide, and water and convert them into food, and Cellular resipration is the process by which organisms use oxygen to break down glucose and convert it to usable energy. That means that Option B can be crossed out, along with Option C. In Option A, the products of photosynthesis are not the reactants of cellular respiration, but rather the user of the energy that Cellular respiration provides. That means you can cross out Option A, and now you are left with Option D as your answer.
Answer:
A. The products of photosynthesis are the reactans of cellular respiration

Some Eukaryotic Organisms
- Mushrooms
- Dogs
- Lizard
Some Prokaryotic organisms are Bacteria, Archaea and E.Coli and Some Eukaryotic organisms are mushrooms, dogs and lizard.
What is the difference between prokaryotic and eukaryotic cells?
Prokaryotic cells are cells without a nucleus. Eukaryotic cells are cells that contain a nucleus. Eukaryotic cells have other organelles besides the nucleus. The only organelles in a prokaryotic cell are ribosomes.
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.
Eukaryotic cells are cells containing membrane-bound organelles and are the basis for both unicellular and multicellular organisms. In contrast, prokaryotic cells do not have any membrane-bound organelles and are always part of unicellular organisms.

How is structure of DNA adapted to its function
Answer:
Deoxyribonucleic acid is the macromolecule carries the genetic information. It has two phosphate sugar back bone chains which are joined together with the help of nucleotides (A, T, G, and C). This set of nucleotide refers as gene. These genes define the primary function of DNA to carry genetic information. This DNA structure gets coiled in manner that can carry large amount of information. These nucleotide sequences have ability to get transcribed into protein molecule with the help of translation and transcription factors.
One strand of sequence is sufficient to maintain coding sequence. The pair wise structure helps in case of one strand of structure get damaged and it required in process of replication.
Base stacking provides the stability in the structure of the DNA. The corresponding nucleotides combine with other molecule and minimize the hydrophobic effect. This molecule combines in the perpendicular alignment to the DNA base line.
It often found that TATA box on 5’ end. It is found that on 5’ because process starts from 5’ end and TATA box have A, T nucleotide. These molecules have double hydrogen bond, which is weaker then G, C pair.
Explanation:
The structure of DNA adapted to its function - DNA contains the instructions needed for an organism to develop, survive and reproduce.
DNA sequencesDNA has nucleotide made up of pentose sugar and phosphate backbone, and nitrogenous bases in a particular sequence.The sequence converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodiesDNA winds into a double helix, with hydrogen bonding between the bases of each strand like the rungs of a ladder.The order of nucleotides in a gene dictate the amino acid sequence of the proteinDNA acts to store information while proteins are the effector molecules.
Thus, The structure of DNA adapted to its function - DNA contains the instructions needed for an organism to develop, survive and reproduce.
