Why the tropical forest has a more lush plant life than the tundra in regards to how fast things decompose.
Answer:
Because of Nitrogen
Explanation:
Nitrogen seems to be much difficult for plants to acquire because they can only consume nitrogen when it is combined with oxygen or hydrogen, which is why tropical forests have a lusher plant growth than tundra.The decomposition process is the secret to maintaining the nitrogen cycle going since the bulk of fixed nitrogen arrives from decaying organisms and faces being broken down by bacteria.Will award 100 poins :)))
Of the visible light spectrum, the rate of photosynthesis is greatest under?
A) red light
B) blue light
C) orange light
Answer:
A) red light
Explanation:
Blue light is absorbed not only by chlorophyll, but also by carotenoids, and some carotenoids are not in the chloroplasts; further, carotenes and xanthophylls make up the carotenoids. Carotenes do not transfer absorbed energy efficiently to chlorophyll, and thus some part of absorbed blue light is not going to photosynthesis. On the other hand, all of red light is absorbed by chlorophylls and used effectively.
The rate of photosynthesis is greatest under red light.
Red and blue light are both absorbed by the xanthophylls and carotenes. The absorption of blue light is higher than that of red light in the xanthophylls and carotenes.
However, red light is solely absorbed in the chlorophyll and not blue light. As such, the absorbed red light is utilized for photosynthesis directly.

Which statement correctly describes how an organelle contributes to the ability of the cell to perform life functions?
The lysosomes digest food and break down cell parts when they die and the cell membrane prevents all harmful substances from entering the cell. So, the correct options are C and D.
What is Cell?Cell is defined as the smallest unit that can live on its own and that makes up all living organisms and body tissues where the cell has three main parts: cell membrane, nucleus, and cytoplasm. The cell membrane surrounds the cell and controls the movement of substances into and out of the cell.
A single cell is itself an organism. For example, yeast or bacteria. Other cells acquire specialized functions soon after they mature which acquire unique functions when they mature. They cooperate with other cells and become the building blocks of multicellular organisms such as humans and animals.
Therefore, the correct options are C and D.

How are the phases of Venus different than the phase of our moon?
Answer:
Venus is an inferior planet. Because Venus is so close to the Earth and lies nearer to the Sun, it shows phases, similar to the way the Moon does. It also is closer to us near inferior conjunction (bigger) than at superior conjunction (smaller), and so its angular size changes as the distance between us varies.

What is the role of enzymes in the DNA replication process?
A. Enzymes read the DNA code and build a new DNA molecule from scratch.
B. Enzymes link together to form a template for a new DNA molecule to be built.
C. Enzymes split the DNA molecule into two rails and then transport corresponding nitrogenous bases to each rail.
D. Enzymes link adjacent nucleosides together, becoming an integral part of the structure of the new strands of DNA.
Answer: C. Enzymes split the DNA molecule into two rails and then transport corresponding nitrogenous bases to each rail.
Explanation: This would be known as the double helix because it is being split.
Different enzymes are involved in DNA replication: DNA polimerase, primase, helicase, ligase, and topoisomerase. The correct option is C. Enzymes split the DNA molecule into two rails and then transport corresponding nitrogenous bases to each rail.
---------------------------------------------
DNA Replication starts in some specific place named replication origin.
Helicase
This is the first enzyme that works in the replication origin. It separates the DNA into two strands allowing the replication forks to advance by unwinding the DNA. It breaks hydrogen bonds between nitrogenated bases pairs.Topoisomerase impedes the DNA double helix near the replication forks to get too coiled when the DNA is opening.
DNA polymerase III
This enzyme is responsible for DNA elongation. It is in charge of adding nucleotides to the growing chain, from 3' to 5' extremes. It includes only nucleotides that complement the original strand. They need to recognize a primer to begin.Primase is in charge of synthesizing primers.
DNA polymerase I eliminate ARN primers and substitute them with DNA.
DNA ligase seals the gaps that remain after replacing the primers.

In a well-structured paragraph, evaluate the experimental design of the investigation into the osmolarity of different types of apples for adequate controls and measurement techniques .
Answer:
To determine the osmolarity of two types of apples in this experiment they use four sucrose solutions and twenty-four apple cylinders. They let these cylinders stand overnight in separate beakers of sucrose solutions, and repeat the procedure for the second variety. For the first variety, they record the temperature for the sucrose solution and remove the core to determine their combined mass. Then they will record the final masses and calculate percent change by using the percentage change in mass formula. After, they repeat these same steps for the second variety.

ATP and photovoltaic cells are similar because
A. they are both key components of plant cells.
B. they both produce chemical and electrical energy.
C. they are both key components of solar panels.
D. they both use energy from the sun to separate electrons from atoms.
Answer:
D. They both use energy from the sun to separate electrons from atoms.
Explanation:
In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH.
Photovoltaic systems use the photons produced by sunlight to generate direct current (DC) electricity. When the photons hit the panel they are absorbed by the panel's semiconducting silicon material.
Explain how Earth’s atmosphere affects solar radiation
Answer:
Explanation: Three atmospheric processes modify the solar radiation passing through our atmosphere destined to the Earth's surface. These processes act on the radiation when it interacts with gases and suspended particles found in the atmosphere.
The three main atmospheric components that absorb radiation are ozone, carbon dioxide, and water vapour. The sun's UV energy, which is detrimental to the majority of living organisms, is absorbed by ozone. Without the atmosphere's protective barrier, sunlight would cause our skin to burn.
What Earth’s atmosphere affects solar radiation?29% of the solar energy that strikes the Earth is returned to space as a result of reflection, largely from clouds but also from other brilliant surfaces and the atmosphere itself. Approximately 23% of the energy entering the environment is absorbed by atmospheric gases, dust, and other particles.
Therefore, The solar radiation that enters our atmosphere and is directed toward the Earth's surface is altered by three atmospheric processes. When radiation interacts with gases and suspended particles in the atmosphere, several processes impact the radiation.

Why does a lunar eclipse effect a larger area?
Answer:
A lunar eclipse occurs when the Moon moves into the Earth's shadow. This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned (in syzygy) with Earth between the other two, and only on the night of a full moon. The type and length of a lunar eclipse depend on the Moon's proximity to either node of its orbit.

B. C C T G A C T A A
C. G G A C T G A T T
D. T T A G T C A G G
The following DNA strand "GGACTGATT" has the complementary mRNA strand "CCUGACUAA". Thus, the correct option is A.
What is mRNA?An mRNA is a type of RNA which is found inside cells. mRNA is also known as messenger RNA. The mRNA molecules carry genetic information which is required to make proteins in the cell. They carry the information from DNA in the nucleus of the cell to the cytoplasm where the proteins are synthesized.
The mRNA synthesized complementary to the sequence of DNA strand can be determined. As A base pairs with U and vice versa and C base pairs with G and vice versa. Thus, the sequence of mRNA synthesized from the DNA sequence "GGACTGATT" will be "CCUGACUAA".
Therefore, the correct option is A.
