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.

Explanation:
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".

Why is there limited vegetation in the tundra?
Answer:
Frigid temperatures, etc.
Explanation
The tundra has very low temperatures and a layer of permafrost over the soil. It has characteristics similar to the desert and it also has a short summer and a long, freezing winter. Therefore, there are not many flora variations that can thrive in that biome.
Answer:
The tundra experiences little rainfall, which makes the soil devoid of nutrients. The soil is permafrost, or permanently frozen. Both of these factors make it difficult for plants to grow in the tundra.

What's the difference between inference and observation? Give examples of each.
Answer:
A inference is a conclusion reached on the basis of evidence and reasoning.
A observation is an act or instance of regarding attentively or watching
Explanation:
Example for a inference would be - lets say you notice someone isnt acting like theirself you may infer that their not having a good day or their not in a mood
Observation example- when your doing a lab for science you may observe the different types of utensils or the effects of the object you use like oh this is blue or something

Explanation:
Claim Evidence Reasoning. Evaluate the following claim: Meiosis is different than Mitosis.
Answer/Explanation:
Yes, although they have similarities, meiosis and mitosis are different.
SimilaritiesMeiosis and mitosis are both types of cell division that results in the production of daughter cells.
They go through similar processes of prophase, metaphase, anaphase, and telophase.
DifferencesHowever, mitosis produces two genetically identical diploid daughter cells from a diploid parent cell.
Meiosis produces four genetically different haploid cells from a diploid parent cell.
There are two rounds of cell division in meiosis, and only one round in mitosis.

This solution slowly gives off carbon dioxide.
A student set up an investigation to see what
concentration of carbon dioxide is best for
increasing the growth of geranium plants.
Dish containing water
and one tablet
The student:
put a geranium plant in a clear plastic bag
put a dish containing water and one tablet in the bag and sealed the top of the bag.
The student:
set up 5 more experiments each with water and a different number of tablet and left all
the plants in a well-lit place for four weeks.
The student used a clear plastic bag, not a black plastic bag.
Explain why.
Answer:
the clear plastic bag is used for the sunlight penetration to allow photosynthesis to take place (i guess this is the answer I'm not sure tho but think about it) Black plastic bag would prevent the light penetration
2. The thread-like chromosomes are spread

Answer:
When the cell is not dividing, the genetic material is loosely dispersed throughout the nucleus in a threadlike form called chromatin.
Explanation:
Chromatin is the thread-like chromosomes spread throughout the nucleus.
What are chromatin and its functions?Eukaryotic cells' nuclei include a combination of macromolecules called chromatin, which is made up of DNA, RNA, and protein. Heterochromatin (condensed) and euchromatin are the two types of chromatin. The main proteins that make up chromatin are termed histones, which act as bases for the DNA to wrap around to form the "bead-like" structures known as nucleosomes.Functions of chromatin:DNA packagingTranscription regulationChromatin and DNA repair

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.

Answer:
This type of natural selection occurs when there are selective pressures working against two extremes of a trait and therefore the intermediate or “middle” trait is selected for. If we look at a distribution of traits in the population, it is noticeable that a standard distribution is followed: Example: For a plant, the plants that are very tall are exposed to more wind and are at risk of being blown over. The plants that are very short fail to get enough sunlight to prosper. Therefore, the plants that are a middle height between the two get both enough sunlight and protection from the wind.
This type of natural selection occurs when selective pressures are working in favour of one extreme of a trait. Therefore when looking at a distribution of traits in a population, a graph tends to lean more to one side: Example: Giraffes with the longest necks are able to reach more leaves to each. Selective pressures will work in the advantage of the longer neck giraffes and therefore the distribution of the trait within the population will shift towards the longer neck trait.
This type of natural selection occurs when selective pressures are working in favour of the two extremes and against the intermediate trait. This type of selection is not as common. When looking at a trait distribution, there are two higher peaks on both ends with a minimum in the middle as such: Example: An area that has black, white and grey bunnies contains both black and white rocks. Both the traits for white and black will be favored by natural selection since they both prove useful for camouflage. The intermediate trait of grey does not prove as useful and therefore selective pressures act against the trait.
Genes help to define who an individual is inside and out. In addition to visible traits like weight and eye color, psychological qualities such as personality traits, intelligence, risk of mental illness, and more have been linked to genetics.

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.
