Answer:
C
Explanation:
All that is left are the plants capable of surviving in dry conditions; whereas before there were plants that thrived in more marshy conditions. Therefore decreased genetic diversity. The adaptations of the plants will be much less diverse.

In pigeons, the allele B produces blue feathers. The allele W produces white feathers. The B and W alleles are codominant. A blue and white pigeon BW is crossed with a solid white pigeon WW. What percent of the offspring are expected to be blue and white?
Answer:
The correct answer is - 50%.
Explanation:
Codominance is a type of inheritance that takes place when the genotype of an individual organism in heterozygous condition express traits of both alleles.
Cross between blue and white pigeon and pure white:
BW × WW and gametes will be B and W and W and W
B W
W BW WW
W BW WW
There are 50% of BW that is blue and white pigeons

How many genes make up the human genome?
four: adenine, thymine, guanine, and cytosine
23 pairs of genes
20,000–25,000 genes
3 billion genes
Answer:
The correct answer is - 20000, 25,000 genes.
Explanation:
Genes are made by the functional and physical unit of the heredity called DNA. Genes are the precursors or encoded instructions to make a specific protein. Genes can be small or large depending on the DNA bases present in it which can be hundreds to millions in numbers.
According to the Human Genome Project, which found out the total genes present in a human genome between 20000 to 250000 genes approximately.
Thus, the correct answer is - 20000, 25,000 genes.
Genes are the hereditary units, which are present in the coded segments of the DNA. Genes carry the information from parent to daughter cells.
There are 20,000 to 25,000 genes that make up the human genome.
Human Genome Project was conducted for several years, the result obtained was:
The human genome project was an international scientific project, which aimed at determining the base pairs that make up the human DNA.The project estimated that humans consist of 20,000 to 25,000 genes in their genome. Each individual inherits the copies of genes from both parents.Therefore, the correct answer is Option C.

Can humans be considered carbon sinks? If so, for how long? What living organisms are better long-term sinks than humans?
Answer:
Carbon sinks can be natural or man-made. They absorb more carbon than they release, whereas carbon source is anything that releases more carbon than they absorb. ... Together Earth's land and Ocean sinks absorb half of the carbon dioxide emissions.
Explanation:
Humans can be considered carbon sinks - yes, for a lifetime.
living organisms are better long-term sinks than humans - plants or trees.
Carbon sinkanything that absorbs more carbon from the atmosphere than it releasesit is the opposite of a carbon source as a carbon source is anything that releases more carbon than it absorbsHumans release carbon mainly by respiration, however, absorbs very less amount as foodPlants grab carbon dioxide from the atmosphere to use in photosynthesis and only some of this carbon is released to the soil when plants die and decomposeLearn more:

A manufacturing factory is accused of emitting high levels of CO2 into the ecosystem. The factory burns coal to heat steel
drums. The factory uses lake water to cool the drums. The water is poured over the drums and then emptied back into the
lake
Scientist A claims the factory is responsible. The burning of coal releases excess CO2 into the atmosphere. This excess CO2 is
transferred to all areas. The CO2 is not lost throughout the system.
Scientist B clams the factory is not responsible. The CO2 is released directly into the atmosphere, not into the lake. The CO2 is
lost into the upper layers of the atmosphere and not cycled back into the ecosystem
The model represents the cycle of carbon in the atmosphere. Which key issue illustrated in the model would best support Scientist
A's claim?
A)
The model shows a factory creating excess levels of CO2
B)
The model depicts a continuous cycle. An increased level in one area will
increase levels throughout.
The model depicts multiple cycles. The atmospheric cycle would show an
increased level of CO2
The model shows high levels of carbon in the lake. Any change to this level
will have a greater impact on the atmosphere.
D)
The key issue that must be illustrated in the model and best support Scientist A claim is as follows:
The model depicts multiple cycles. The atmospheric cycle would show an increased level of CO2.Thus, the correct option is C.
What is an Ecosystem?An ecosystem may be defined as a place or an area in which individuals of different species live together and interacts with one another for the purpose of food, shelter, and space.
According to Scientist A, the factory is responsible for the excess level of carbon dioxide in the atmosphere. This is absolutely true because the factory burns coal that liberated a high amount of CO2 into the environment.
Apart from this, the factory uses lake water to cool the drums. The water is poured over the drums and then emptied back into the lake. This increases the concentration of CO2 in the lake as well.
Therefore, the correct option for this question is C.

B) Heat is being absorbed to change the substance from a liquid to a gas

Which would have most likely stopped Mendel from finding a pattern in his results?
O A. If seed shape did not have a clearly recessive form
B. If having a smooth seed had been a dominant trait
C. If having a wrinkled seed had been a recessive trait
D. If garden peas produced large numbers of offspring
Answer:
A. If seed shape did not have a clearly recessive form
Explanation:
To study inheritance patterns, Mendel studied a few characteristics of pea plant -e.g. pea colour, shape, plant height. These characteristics had to be very clear dominant and recessive forms to distinguish between, otherwise detecting the patterns would not have been obvious.
For example, if crossing a wrinkled seed plant with a smooth seed plant made a semi-wrinkled plant, Mendel would not have been able to study the inheritance of dominant and recessive traits.
Answer:
A. If seed shape did not have a clearly recessive form.

Which best describes the permeability of a membrane?
O A. The total thickness of the membrane
B. The flexibility of the membrane
C. The number of molecules in the membrane
D. The ability to allow materials to cross a membrane
Answer:
D
Explanation:
D. is correct because the membrane works like a security guard and only allows certain materails to cross the membrane. The definition of permeability is the state or quality that allows something to pass through.
Permeability is a standard of easy motion of liquid and gases through a membrane or material. They allow the transportation and exchange of gases in a cell.
The statement that best describes the permeability of a membrane is:
Option D. The ability to allow materials to cross a membrane.
This can be explained as:
Permeability is a physical property of membranes and substances that allows the other molecules to move through them.It acts as a barrier from substances entering and exiting the cell or membrane and maintains the balance in a system.Therefore, permeability is the allowance of materials across the membrane.

Which surface erosion event does the most short- term damage?
Loss of topsoil from farmland.
Movement of rocks by glaciers.
Occurrence of mud slides after heavy rains.
Pollution of water sources caused by runoff.
Answer:
Occurrence of mud slides after heavy rains.
Explanation:
Soil erosion is defined as the removal of top soil from the land and it affects the fertility of the soil. It is also known as soil degradation.
Soil erosion has both short-term and long-term damage. Short-term damage of erosion includes the occurrence of mudslides after heavy rains which is called landslide. It is a short-term damage because landslides took long-duration to happen and when happened it can be shortly recovered using machines.
Hence, the correct answer is "the Occurrence of mudslides after heavy rains."
