Answer:
They form from burning fossils fuels like coal and oil that put more carbon dioxide in the atmosphere. An example of its negativity affect is the melting ice caps it adds more heat which speeds up the melting process (duh) this is the change in animals and the environment and for and for plants it can cause a negative impact on growth.

DNA is in what form during interphase?
Answer:
During interphase (1), chromatin is in its least condensed state and appears loosely distributed throughout the nucleus. Chromatin condensation begins during prophase (2) and chromosomes become visible. Chromosomes remain condensed throughout the various stages of mitosis (2-5).
DNA is in form during interphase During interphase, the cell DNA isn't condensed and is loosely distributed.
What happens during interphase?A stain for heterochromatin (which shows the placement of chromosomes) indicates this large distribution of chromatin. The equal stain additionally indicates the organized, aligned shape of the chromosomes in the course of mitosis.
Nuclear DNA remains in a semi-condensed chromatin structure throughout the interphase. During the S phase, DNA replication results in the creation of identical pairs of DNA molecules, known as sister chromatids, which are tightly linked to the centromeric region.
During the S phase, the centrosome is duplicated.

A cup is surrounded by air in room temperature
Describe the energy transfer between the water and air if the system is at equilibrium
A.Energy is transfers from air to the water
B. Energy transfers from water to the air
C. Energy transfers back and forth between air and water
D.None of the above
The energy transfer between the water and air if the system is at equilibrium does not carry any transfer of energy. So, the correct option is D.
What do you mean by Equilibrium state?Equilibrium may be defined as a condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs.
When the system is at equilibrium, the energy transfer between water and air surrounding the cup does not take place. It will only take place when there is a difference between the concentration of two solutions or objects.
Therefore, the energy transfer between the water and air if the system is at equilibrium does not carry any transfer of energy.

The evolution of arthropods has led to
Answer:
Arthropods make up almost 80% of all animals; they are jointed legged animals that belong to the Animalia kingdom that include centipedes, millipedes, insects, and spiders. The success of arthropods can mainly be attributed by the following characteristics;
Presence of Exoskeleton.
The presence of exoskeleton that hardens due to the presence of chitin offers a protective cover for arthropods with different environment against advance conditions and also it protects against dehydration.
Varied habitats.
Arthropods can be found in all types of habitats from the soil, water, and land. This feature is the key to their survival since they are widely distributed hence increasing chances of survival.
Bilateral Symmetry.
Arthropods exhibit bilateral symmetry whereby a different portion of their bodies are mirror images, this form is exhibited in higher animals such as humans and dogs, and it facilitates advanced body functioning.
Jointed Legs.
Arthropods exhibit segmented legs that are jointed to allow the development of hard exoskeleton for protection. The jointed legs are specialized for grasping, jumping and running.
Short generation time.
Arthropods exhibit short generation time, which allows for faster adaptation to the environment and survival.
Reproduction strategy.
Arthropods have exhibited a sexual form of reproduction that is more successful in the growth and survival of offspring.
Segmented body.
Arthropods have a segmented body that allows for specialization of body organs and tissues, and this has promoted their success by specializing body organs to different functions.
Which process best explains how antibiotic resistance in bacteria can occur?
Answer:
Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.
Model: Use the Punnett squares below to model each parent combination. After filling in each Punnett square, predict the percentages of black and white offspring.

The active ingredients in many pesticides are chemical compounds that kill organisms such as insects, molds, and weeds. Proponents claim that the use of pesticides improves crop yields and thus protects land and soil by reducing the conversion of forests and wetlands to cropland. Opponents of pesticide use claim that pesticides degrade water and soil quality and that other modern agricultural techniques and practices are responsible for the improved crop yields in recent years. Design a laboratory experiment to determine whether or not a new pesticide (product X) is toxic to minnows, a type of small fish.
Answer:
The active ingredients in many pesticides are chemical compounds that kill organisms such as insects, molds, and weeds. Proponents claim that the use of pesticides improves crop yields and thus protects land and soil by reducing the conversion of forests and wetlands to cropland.
Explanation:
The experiment design would be based on the hypothesis - that higher concentration of the new pesticide product X will result in more mortalities of minnows in the population.
Experiment:
In such type of experiment we required four different tanks with fresh water in each of them and 20 minnows in each as well.Tank 1 with no pesticide would be control in this experiment.concentration of the pesticide in tank 2: 0.05 %, tank 3: 0.1% and tank 4: 0.2%.number of death of minnows in each tank would be count after exposure every day.Experiment should be continue for 30 daysindependent variable: concentration of pesticidedependent variable: number of deaths of minnows each day of exposure.On the given design of the test we can determine whether or not a new pesticide (product X) is toxic to minnows, a type of small fish.

If DNA code consists of only four nitrogenous bases, how can it produce so much variety among
organisms of the same species?
Explanation:
I tnought this will help you
If DNA code consists of only four nitrogenous bases, still it produces so much variety among organisms of the same species with the help of Codons and amino acids sequences.
What do you mean by Nitrogenous bases?Nitrogenous bases may be defined as a molecule that contains nitrogen and possesses the chemical properties of a base. The nitrogenous bases that are found in DNA are Adenine (A), Guanine (G), Thymine (T). and Cytosine (C). Uracil (U) is present instead of Thymine in RNA.
There is a total of 4 nitrogenous bases that are found in DNA and RNA. Each codon codes with the help of three nitrogenous bases. So, total variations = [tex]4^3[/tex] = 64.
But there are only 20 amino acids that are commonly known. Some codons are stop codons, they do not code for any amino acids. While some codons code for the same amino acids.
Therefore, If DNA code consists of only four nitrogenous bases, still it produces so much variety among organisms of the same species with the help of Codons and amino acids sequences.
