After a forest fire what would be the first change in a forest?
Pioneer species are established
A climax community is established
Wind carries seeds to the area and plants grow from these seeds
New soil forms from rock
c because
The first plants to move into the new bare ground after a wildfire are wildflowers or “weeds.” These fast-germinating, leafy herbaceous plants are also known as “forbs” or “ephemerals.” They quickly germinate, grow and produce a new crop of seeds.
Answer:
Pioneer species are established
Explanation:
A forest fire would represent the process of secondary succession.
In secondary succession, the first stage is the growth of pioneer species. The soil still remains, so no new soil needs to be made.
This rich soil allows for pioneer species to grow in the forest.
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.
Explanation:
A species is a particular type of living thing that can reproduce by interbreeding among themselves.

How does the Gulf Stream affect weather in the United States? A. It brings cooler temperatures from the poles. B. It brings cooler temperatures from the tropics. C. The warm surface currents help create storms and fog. D. The cool surface currents produce cooler weather and fog.
Answer: C. The warm surface currents help create storms and fog.
Explanation:
The gulf stream can be defined as strong ocean currents that brings about the warm wind currents from the oceanic water of the gulf of Mexico to the eastern coastal areas of the United States. These wind currents bring warm weather conditions in the United States. The strong wind currents can also cause storms and fog in the coastal areas of the United States.

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

What is the relationship between population number and carrying capacity in a stable population
Answer:
As a population grows in an area, a population may experience the effects of increased densities. In a given area, is the maximum population size of the species that the environment can sustain is called the carrying capacity. Carrying capacity is determined by the amount of available resources (food, habitat, water).

Why does evolutionary theory absolutely require the earth to be very
old?
Answer:
Mainly because Evolution takes millions and millions of years to happen.
Explanation:
Evolutionary theory require earth to be very old because the process of evolution takes millions of year to happen.
What do you mean by evolution ?Evolution is the process through which a population of organisms evolves as new generations replace ancestors. Individual species do not evolve; rather, communities of organisms do.
Natural selection processes like as environmental change, predation, or human disturbance create evolutionary adaptations, and these processes must continue and grow widespread for the change to remain and accumulate. That happens less frequently and slowly than you may expect.
Scientists have determined that Earth is 4.54 billion years old, with a 50 million year error, by dating the rocks in its ever-changing crust as well as those in Earth's neighbors, including the moon and passing meteorites.
Therefore, the Earth needs to be very old for evolutionary theory to be true.

Explanation:
NOTE - ANSWER IN PHOTO
REAL NAME - SHRESTH DUBEY
Individual organisms making up a population may be evenly distributed, randomly distributed with no discernible distribution pattern or grouped together. These distribution patterns are called uniform, random, and clumped.
Distribution patterns (also known as species dispersion patterns) refer to the distribution of individuals within a population at any point in time.
Dispersion is the process of a group of living things expanding the area or range in which they live. Dispersion occurs when individual organisms move from the area that they occupied before, or where they were born, to new areas.
Uniform means the population is uniformly distributed, random means the population is randomly distributed, and clustered means the population is clustered.
The labeled diagram showing the population distribution patterns is given below.

Bats are common in Texas especially in rocky regions bats with longer hang claws have demonstrated higher fitness because of their ability to cling to rock while resting this adaptive on is becoming more frequent in the population.What mechanism of evolution is this
Answer:
Natural selection
Explanation:
Natural selection is the mechanism of evolution in which organisms evolve in order to adapt the changes in the habitat for their survival. Living organisms are naturally variable and adjust themselves according to their surroundings.
In the given example, bats in Texas evolve themselves with longer hang claws to adapt the rocky nature of the surrounding. These longer hang claws provide them the ability to cling to the rock, which is an adaptive feature of bats that is influenced by the environment.
Hence, the correct option is "Natural selection".

In one plant species petal color follows INCOMPLETE DOMINANCE. If there
are alleles for both red and white plants, what would a heterozygous plant's
phenotype be?
Red
Pink
White
Red and White
Answer:
Pink
Explanation:
Incomplete dominance is when one allele is not entirely dominant over the other. The resulting phenotype of the heterozygote is intermediate between the two alleles. That means the flowers would be pink.
Red - no, this would be true if red was dominant to white
Pink - yes, this is an intermediate phenotype
White - no, this would be true if white was dominant over red.
Red and White - no, this would be true if the alleles were co-dominant and both equally but independently expressed.
