I need help with ecosystems!which of the following are characteristics of a temperate broadleaf forest? (select all that apply)A. They experience all four seasonsB. They contain mainly coniferous treesC. They are very dry and recieve little or no rain waterD. They can be found along the Atlantic coast of the united states
Answers
Considering the temperate broadleaf forest, we can say by its name that plant species present in this ecosystem need a significant amount of humidity to develop broadleaf, so the option stating that they are very dry and receive little or no rainwater (C) can be discarded.
In this same way, we can say that considering the second answer option, coniferous trees are not the main element in this kind of habitat, since these plant species are mostly found in ecosystems that are in their proper ecosystems, which are so characterized by its presence, at the point that the very ecosystem has its name on its, so this (B) is not the answer too.
So the answers could be that they can be found on the Atlantic Coast of the United States, and they experience all four seasons in its extent. A, and D.

The cichlid is a colorful fish found in freshwater lakes. There are over a thousand species of cichlid fish today. If a species of cichlid became extinct, the niche the fish filled within the ecosystem would be left open. Explain how an available niche after extinction can lead to speciation.
Answers
The niche available after extinction can lead to speciation because there would be an imbalance, making resources formerly occupied by extinct fishes vacant, providing the emergence of new species to take the place of the extinct species.
When does speciation occur?Speciation can be understood as processes that lead to the formation of new species. They occur due to differences in the genome of different populations of the same species that caused reproductive isolation and, consequently, the appearance of two different species.
With this information, we can conclude that Speciation is the process of formation of new species from lineage separation events from preexisting species.

The body of a woman is found buried in a field although much of the body has decomposed her clothes are mostly intact she appears to have died of Suffocation but has no other visible injuries however there are blood stains on both her shirt and pants based on the location and description please suspect this is the body of the woman who went missing about 15 years ago what rational might have forensic scientists have been choosing whether it's worth it to analyze blood signs to see if they match suspect?
A. The blood would no longer produce DNA
B. the dried blood can still produce nuclear DNA after 20 years
C.there is probably not enough blood to get a good sample
D. the blood stains probably belong to the victim
Answers
B. the dried blood can still produce nuclear DNA after 20 years. Option B is more correct. Nuclear DNA can be extracted from decades-old dried bloodstains, although the quality and quantity may be lower than new samples.
Option A is inaccurate. Depending on storage and other variables, dried bloodstains from several decades ago can provide useable DNA.
Option C, - forensic experts may also consider. It may not be worth the time and money to examine minor bloodstains or degraded DNA.
Based on the facts supplied, option D, seems unlikely. The bloodstains may belong to the victim or another criminal.
In conclusion, forensic experts would likely examine the bloodstains' age, condition, and amount when choosing whether to analyse them for a suspect match. They may also assess the cost, time, and investigation value of the analysis.

The Kinetic Energy of the particles did not change.
The particles of the substance resulted in a high Kinetic Energy.
The particles of the substance initially had high Kinetic Energy.
Answers
The particles of the substance initially had high Kinetic Energy.
Does the kinetic energy of a particle change as the temperature changes?Gas particles move quickly in all directions and regularly collide with one another and the container's side. The particles gather kinetic energy and accelerate as the temperature rises. The particles' real average speed is influenced by their mass and temperature.
In liquids, particles are quite close together and move with random motion throughout the container. Due to the closer proximity of the particles, collisions between them happen more frequently than in gases even if particles are moving quickly in all directions.

What are the 4 major parts of natural selection? Describe each.
Answers
Answer:
The four major parts of natural selection are:
Variation: This refers to the genetic differences that exist among individuals within a population. No two individuals are exactly alike, and these genetic differences can affect traits such as size, color, behavior, and other characteristics.
Heritability: This refers to the ability of an individual's traits to be passed down to their offspring. If a trait is heritable, it means that the genetic basis for that trait can be passed on from one generation to the next.
Differential Reproduction: This refers to the fact that individuals with certain advantageous traits are more likely to survive and reproduce than individuals with less advantageous traits. This means that the advantageous traits will become more common in the population over time.
Selection: This refers to the process by which advantageous traits become more common in a population over time. Selection occurs because individuals with certain advantageous traits are more likely to survive and reproduce, passing their traits on to their offspring.
Together, these four parts of natural selection drive the evolution of populations over time. As advantageous traits become more common, the population becomes better adapted to its environment, and may even evolve into a new species if the changes are significant enough
Explanation:
Hey I got This ASAP So only Mark Me As Brainliest
Answer: Overproduction and Competition- There are more offspring born than the environment can support. This produces competition for limited resources in the ecosystem.
Genetic variation- There are naturally occurring variations in a population because of meiosis, which can create new allele combinations. Variation can also be introduced by mutations, or changes, in DNA. These mutations can sometimes be helpful to the organisms by creating alleles of genes that give the organism a survival or reproductive advantage.
Selection- The organisms with the most helpful traits that can find resources (food, water, mates) can survive and reproduce.
Inheritance and Adaption- Traits are passed from parent to offspring. Some of these traits are beneficial and help the individual survive better and reproduce more often in the environment. These traits are known as adaptations, and they tend to accumulate in a population due to the environment and natural selection.

Answers
Based on the information provided above, the dependent variable is the height of each plant with respect to each fertilizer. The utilization of fertilizer is an independent variable. While the last group that Javier treated with plain water is the control group in this experiment.
What is an Independent variable?An independent variable may be defined as a type of variable that significantly stands alone and isn't altered by the other variables you are trying to determine. These types of variables do not depend on other factors during the course of an experiment.
According to the experiment conducted by Javier, the growth of the plant directly depends on the type of fertilizer and it may vary with respect to each fertilizer. So, it is considered under the dependent variable.
The utilization of fertilizer does not depend on any factor during the course of the experiment. So, it is classified under an independent variable. While the group of plants that do not have any interaction with fertilizers and are treated normally comes under the category of control groups.

The gas produced in the burning of fossil fuels that has been most closely linked to rising atmospheric temperatures is carbon dioxide. Option D
What is the burning of fossil fuel?
As a byproduct of combustion when fossil fuels like coal, oil, and natural gas are used to produce energy, carbon dioxide is discharged into the atmosphere.
As a greenhouse gas, carbon dioxide absorbs heat from the sun inside the Earth's atmosphere, creating the greenhouse effect, which causes global warming. The Earth's natural greenhouse effect, which keeps the globe warm enough to support life, is caused by this phenomena.
