Answer:
The correct answer is - option D.
Explanation:
Mendel also performed this type of dihybrid cross that the genes for pea shape color assort independently of each other.
In this punnet square: there is a genotype ratio close to 9:3:3:1 of 9 = round-seed plants with green pods, 3 = wrinkled-seed plants with green pods, 3 =round-seed plants with yellow pods, and 1 = wrinkled-seed plants with yellow pods.
This is an expected ratio with an independent assortment of dominant and recessive alleles.
Population dispersion is:
Three dispersion types:
Answer:
three basic patterns: they can be more or less equally spaced apart (uniform dispersion), dispersed randomly with no predictable pattern (random dispersion), or clustered in groups (clumped dispersion).

In the Florida map shown below, use the law of superposition to determine which rocks are oldest? Map of Florida identifying four different kinds of rock strata. The top layer of quaternary rock is labeled A; the bottom layer of quaternary rock is labeled B; the top layer of tertiary rock is labeled C; the bottom layer of tertiary rock is labeled D. Public Domain A B C D
Answer:
A
Explanation:
By the law of superposition, the oldest rocks are the bottom layer of quaternary rock, labeled. The correct option is A.
What is the law of superposition?
One of the geological laws that geologists use to calculate the relative ages of strata or layers, is the law of superposition. According to this theory, rock layers are stacked or deposited one on top of the other.
The bottom will have the oldest rock strata and the top will have the youngest. Quaternary rocks are considered as oldest rocks. They can be 2.6 million years ago.
With climatic changes and the heat and pressure from the earth's crust, the rocks evolve and convert into quaternary rocks.
Thus, the correct option is A. the bottom layer of quaternary rock is labeled.

Answer:
Mariflower needs more water and carbondioxide gas.
Explanation:
The increase of precipitation and nearby factories increases the population of mariflower because mariflower needs more water for their growth and has no effect of pollution that is produced on this mariflower. Due to more industries, more carbondioxide gas is emitted from them which is required by mariflower in the process of photosynthesis so that's why the population of mariflower increases with rainfall and industries.

The process of reproduction is not essential for the survival of an
individual but reproduction is essential for the continuation of a
species. (True or False)
Answer:
true
Explanation:
While it is one of the fundamental characteristics of living things, it is not an essential life process. An individual can live without reproducing, but, a species cannot survive without reproduction. Reproduction is thus essential for continuation of the species.

Bacteria that act as producers in an ecosystem by using energy from chemicals in the environment to make carbon compounds such as glucose are called:
a
chemoheterotrophs
b
photoheterotrophs
c
photoautotrophs
d
chemoautotrophs
Answer:
D) chemoautotrophs
Explanation:
Chemoautotrophs are cells that create their own energy and biological materials from inorganic chemicals.
In nature, “autotrophs” are organisms that don’t need to eat because they make their own biological materials and energy. This term comes from the Greek “auto” for “self” and “troph” for “to eat” or “to feed.”
Autotrophs form the basis for all food chains: they are the organisms which create sugars, proteins, lipids, and other materials for life. All other organisms survive by eating autotrophs, or other organisms that are fed by the autotroph food chain.
The two major types of autotrophs are chemoautotrophs and photoautotrophs. Photoautotrophs use energy from sunlight to make their biological materials. These include green plants and photosynthesizing algae.
This flow chart may be useful in determining whether an organism is an autotroph, and if so, which kind it is:
Troph flow chart
Chemoautotrophs, on the other hand, derive energy for their life functions from inorganic chemicals. They feed on chemicals that are good electron donors, such as hydrogen sulfide, sulfur, or iron.
Like all autotrophs, chemoautotrophs are able to “fix” carbon. They take atoms of carbon from inorganic compounds, such as carbon dioxide, and using it to make organic compounds such as sugars, proteins, and lipids.
Chemoautotrophs are commonly found in environments where plants cannot survive, such as at the bottom of the ocean, or in acidic hot springs.
Some types of chemoautotrophs also play critical roles in plant-based ecosystems. Although plants perform carbon fixation in these ecosystems, many plants rely on chemoautotroph bacteria to fix nitrogen, which is necessary to make amino acids and proteins.
Function of Chemoautotroph
Basis of Ecosystems Without Sunlight
Chemoautotrophs form the basis of the energy pyramid for ecosystems where photosynthesizers can’t survive. Without chemoautotrophs, life would only be able to exist where energy could be derived from sunlight.
They are the basis of some deep sea ecosystems, such as those existing around deep sea hydrothermal vents.
Scientists have speculated that chemoautotrophs could form the basis of life on planets which receive less sunlight than earth.
Nitrogen Fixation
One type of chemoautotroph, Nitrosomonas, plays the crucially important role of fixing nitrogen in the soil of some ecosystems. Like most chemoautotrophs, Nitrosomonas can take toxic chemicals – in this case ammonia – and turn it into materials for life.
Nitrosomonas harvests nitrogen from ammonia, and fixes it into organic compounds which can then be used to produce amino acids, proteins, and other crucial materials for life.
Possible Origin of Life
We have no fossils of the first cells on Earth, so we are not able to say at this time what they were like. We know that they had to be autotrophs, since they would have had to produce all of their own organic materials.
Some scientists think that the first cells were likely photoautotrophs, deriving energy form sunlight – but other scientists think the first cells may have been chemoautotrophs, and that photosynthesis may have evolved later.
If true, this would make all of us descendants of chemoautotrophs!
Examples of Chemoautotrophs
Nitrosomonas
Nitrosomonas is a genus of nitrogen-fixing bacteria.
As you may have guessed, “nitrogen fixation” means taking nitrogen from inorganic compounds, such as ammonia, and assembling it into organic compounds, such as amino acids.
Nitrogen fixation is crucial for many ecosystems, even some which rely primarily on plants. Many plants cannot fix their own nitrogen – meaning that they require nitrogen-fixing bacteria in the soil, or they cannot obtain the nitrogen compounds they need to live.
Nitrogen fixation is an extremely important concept in agriculture, where many crops cannot perform nitrogen fixation themselves. To ensure that the soil contains enough organic nitrogen compounds to grow, farmers much either make sure that there are enough nitrogen-fixing bacteria present to sustain their crops, or add artificial nitrogen compounds in the form of fertilizers.
Of note, some nitrogen-fixing bacteria have developed permanent symbiotic relationships with certain plant species. These include the symbiotic bacteria found in nodules on the roots of “nitrogen-fixing” plants such as legumes. However, these nitrogen-fixing bacteria are not chemoautotrophs, as they have evolved to rely upon their plant hosts for food. They are no longer autotrophs, as they are no longer able to feed themselves.
Other types of nitrogen-fixing bacteria remain independent, and are still chemoautotrophs.

Alaskan Wood Frogs can freeze up to 60 percent of their body. The frogs build up their glucose (sugar) concentrations in tissues and organs of the frog. This
helps prevent the cells in the tissues from shrinking or dying
Which of the following BEST explains how this adaptation increases the probability the Alaskan Wood Frog will survive in this environment?
When food sources are scarce, this allows the frog to survive until more food is readily available.
Due to the large terrain of Alaska, the frog can freeze itself to preserve energy while traveling across the state.
When harsh winter conditions develop in the area, the frog can prevent the change in the environment from affecting its homeostatic processes.
As predators seek out the frog, its senses allow it to notify the internal processes to freeze. This prevents the predator from being notified there is prey

Explanation:
In Mendel's monohybrid cross of purple-flowered and white-flowered peas, all members of the F1 generation had the __________ phenotype because their genotype was __________ at the flower-color locus.
Answer:
All members of the F1 generation had the Purple phenotype because their genotype was Pp at the flower locus.
Explanation:
Monohybrid cross is a cross involving one trait(for example Flower color).
When Mendel crossed true breeding pea plants that differed in flower color ie Purple flowered pea plant(PP) is crossed with White flowered pea plant(pp),all the seeds of F1 generation were purple.
The white flower trait did not appear in the F1 generation because the purple flower trait completely masked the white flower trait . Thus ,Purple flower trait (PP) is dominant over white flower trait(pp).
So,although the genotype of F1 seeds is Pp,the phenotype is purple flower color because the allele" P" is completely dominant over the allele "p".

The law of conservation of mass states that matter can/cannot be created
or destroyed, even after a chemical change
a. Can
b. Cannot
Answer:
Cannot
Explanation:
The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.
