Answer:
The mutagen might alter the DNA sequence, thereby altering the accessibility to transcription factors and thus activate the expression of oncogenes involved in cell proliferation
Explanation:
The DNA molecule consists of two antiparallel strands of nucleotides that wind around each other. Each DNA strand is formed by a backbone containing sugar (deoxyribose) and phosphate groups. This arrangement allows for DNA replication and transcription (and consequently also protein synthesis) to occur. If a mutagen agent binds to DNA, this might modify its structure, thereby altering DNA replication and transcriptional activity.

Which step is not part of a normal convection cycle?
A.
Unequal heating creates a pressure difference.
B. Air flows from a high-pressure area to a low-pressure area.
C. Cooled air sinks toward the surface, creating a low-pressure area
D. Warmed air sinks, creating a high-pressure area as it falls.
above it.
Answer:
D. Warmed air sinks is not a normal convection cycle outcome
Explanation:
Warm air is buoyant and rises. Cold air is dense and sinks.
Think of fog in the air. Fog forms in low/cool areas, as the sun comes out and warms up the atmosphere the upper atmosphere, heat flows to cold so upper atmosphere air displaces the fog.
Space heating, the steam or hot water radiators are placed along the floor typically causing convection of warm air to rise up over windows and cold walls, breaking up cold air drafts.

You would MOST LIKELY find a savannah grassland biome in an area with
A)
50 cm of precipitation.
B)
100 cm of precipitation.
200 cm of precipitation.
D)
250 cm of precipitation.
Answer:
D
Explanation:
Savannah grassland biome is found in an area with an average precipitation of 76.2-101.6 cm. Therefore, option B is correct.
What is the savannah grassland biome?A region of grassland with scattered trees or groups of trees is how the savanna biome is frequently defined.
The savanna is a dry environment, making it difficult for tall plants like trees to flourish. The trees and grasses that thrive on the savanna have adapted to the dry climate and limited water supply.
In regions with savanna growth, a tropical wet and dry climate is prevalent. The annual precipitation averages between 30 and 50 inches, while the mean monthly temperatures are at or above 64 degrees Fahrenheit. Less than 4 inches are received per month during the dry season for at least five months out of the year. Hence, option B is correct.

What occurs after sunlight is absorbed by a chloroplast?
A. The light energy is used for the production of a carbon dioxide and water,
B. The light energy is converted to a glucose molecule
C. The light energy is converted to green light, giving the leaf its color.
D. The light energy is distributed throughout the cell to be used by basic cell functions.
Answer:
B
Explanation:
A cannot be true as photosynthesis requires carbon dioxide and water and uses light energy to break bonds and form oxygen and glucose
C cannot be true as chloroplasts contain chlorophyll which gives the cell its green colour by not absorbing green wavelengths of white light
D is not right as I do not believe photosynthesis is a basic function

Why does the body produce carbon dioxide if it is harmful to the human
body?
Answer:
Carbon monoxide can kill. The gas forms when there is not enough oxygen to produce carbon dioxide -- essentially when the carbon in fuel is not burned completely. Carbon monoxide prevents oxygen in the blood from being carried throughout the body, causing asphyxiation.

suggest two factors other than the rate of nitrogen fixation that may affect the avality of nitrogen in the marine ecosystem
Answer: run off from land/rivers and phytoplankton blooms
Explanation:
Nitrogen, particularly as nitrate is easily leached from soil. Human agriculture relies on fertilisers with significant nitrate content that applied at levels higher than it can be used. The balance end up as runoff, much of which ends up in
The two factors that are other than the rate of nitrogen fixation that fit the marine ecosystem are runoff from the land or rivers and the phytoplankton blooms
Waht is nitrogen fixation ?Nitrogen fixation refers to the chemical process by which molecule N2 has a strong Tripple covalent bond and in the air, it gets coveted into NH3 or a related nitrogenous compound that is typically in soil or aquatic system.
The fixation is essential for life as inorganic nitrogen compounds are needed for the biosynthesis of nitgen-containing organic compounds like amino acids.
As nitrogen is easily found in soil and can be added by fertilizers it ends as runoff and damages the ecosystem.

Explain how iron band formations are
evidence for the evolution of Earth’s
atmosphere.
Answer:
Photosynthetic organisms were making oxygen, but it reacted with the iron dissolved in seawater to form iron oxide minerals on the ocean floor, creating banded iron formations. ... The oxygen that is now in the Earth's atmosphere was not there at the beginning.
Explanation:
Band formations are thought to develop from cyanobacteria. It was developed as product of cyanobacteria photosynthesis.
What is the other name of cyanobacteria ?The other name of cyanobacteria is blue green algae.
The oceans must change between aerobic and anoxic situations. This characteristic makes banded iron development of direct indicators of oceanic oxygen levels, providing us with a data of Earth's oxygenation.
Banded iron formations are brought to have formed in sea water as the consequence of oxygen production by photosynthetic cyanobacteria. The oxygen joined with dissolved iron in Earth's oceans to form insoluble iron oxides which precipitated out forming a thin layer on the ocean floor.
