Explanation:
Ecologists have found that interactions among organisms come in several different forms. In antagonistic relationships, organisms compete for resources, spread disease to their neighbors, or consume each other. In other cases, species with large structures become habitats for smaller organisms.
describe what is happening to the population of bacteria
Answer:
Bacterial populations employ native defenses against antibiotics that are analogous to the activity of protonophores. These mechanisms disrupt membrane electrochemical gradients that enable bacterial populations to establish subpopulations of drug-tolerant persisters

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.

Explain how the TATA box and transcription factors work together to ensure that RNA polymerase is transcribing the correct region of the DNA molecule.
Answer:
How does RNA polymerase know where to start transcribing a gene?
To begin transcribing a gene, RNA polymerase binds to the DNA of the gene at a region called the promoter. Basically, the promoter tells the polymerase where to "sit down" on the DNA and begin transcribing. ... A promoter contains DNA sequences that let RNA polymerase or its helper proteins attach to the DNA.
TATA box and transcription factors work together to ensure that RNA polymerase is transcribing the correct region of the DNA molecule.
What is transcription?Transcription, the synthesis of RNA from DNA. Genetic information flows from DNA into protein, the substance that gives an organism its form.
The TATA box is able to define the direction of transcription and also indicates the DNA strand to be read. Proteins called transcription factors can bind to the TATA box and recruit an enzyme called RNA polymerase, which synthesizes RNA from DNA.. The TATA box marks a point just before the point at which transcription begins, so that RNA polymerease transcribe the correct region of DNA molecule.

Describe the advantage of broad-leaved trees losing their leaves as winter sets in and the advantage of needle-leaved trees keeping their leaves if they are in poor soil
Answer:
The advantage of shedding broad leaves in the winter is to conserve the energy that needs to expand in order to provide heat to each part of the plant including leaves as in winters it becomes very dry and cold. If they do not shed their leaves they have to spend more energy to spend energy on leaves.
Needles like leaves have a thick cuticle layer that prevents from losing water in dry conditions or conditions with a limited amount of water in the soil. These leaves also help in photosynthesis by capturing more sunlight as they have a larger surface area. These adaptions can live in poor soil, rain and snowy conditions.
In humans, hair color and hair type are controlled by simple dominance. Brown hair (B) is dominant over blonde hair (b). Straight hair (H) is dominant over curly hair (h).

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.
