What can regulate the functioning of a gene? Choose the best answer.
Answer:
transcription and RNA processing
Explanation:
It is regulated during transcription and RNA processing, which take place in the nucleus, and during protein translation, which takes place in the cytoplasm. Further regulation may occur through post-translational modifications of proteins.

Which variable is measured in an experiment?
dependent variable
experimental variable
independent variable
The Dependent variable is measured in an experiment. Thus, the correct option is A.
What is a Dependent variable?A dependent variable may be defined as a form of variable in experimental studies that never stands alone. The value of this variable significantly depends upon the independent variable.
The fluctuation in the independent variable may typically induce the dependent variable to be altered. It is the variable that is being measured or tested in a scientific experiment.
While the independent variable is one that stands alone in a given set of experimental studies descriptively. Its value does not depend on any sort of other variables. While the experimental variable is not frequently observed in any experimental analysis.
Therefore, the Dependent variable is measured in an experiment. Thus, the correct option is A.

name four cycles that help to recycle matter in the biosphere
Answer:
Nitrogen cycle
Carbon cycle
Sulfur cycle
Phosphorus cycle
Explanation:
The material cycle refers to the pathway through which important materials in the biosphere take from their source of production to where they are utilized and back to their source of production. It can also be defined as the pathway by which important materials move between the living and non-living components of the earth.
The important materials include nitrogen, carbon, sulfur, phosphorus, etc. The cycles that help to recycle these materials are named according to the name of the material. Hence, there is a nitrogen cycle, carbon cycle, sulfur cycle, and phosphorus cycle respectively.

Question 5 (4 points)
Which is a correct statement regarding microscope use?
You should always begin with the lowest power objective lens.
This highest power objective lens is generally the shortest one.
You should always start with the highest power objective lens.
Once you center under low power, you will not recenter again.
Answer:
Once you center under low power, you will not recenter again.
Explanation:
The correct option would be that once you center under low power, you will not recenter again.
One can start focusing a slide using the x10 or x40 objectives, it does not have to always be the x10 objective and it is never advisable to start with the highest power objective. Also, the highest power objective lens is the longest and not the shortest one.
However, once the field diaphragm has been centered under low power, one does not need to center again but only to refocus.

List 3 sources of evidence for the endosymbiotic theory.
Answer:
DNA, RNA, Ribosomes And Protien Synthesis.
The endosymbiotic theory states that mitochondria and chloroplasts in eukaryotic cells were once prokaryotes engulfed by an early eukaryote.
The lines of evidence for this theory include:
Both mitochondria and chloroplasts have their own DNA that resembles DNA from prokaryotic organisms (i.e., a circular DNA molecule).Both mitochondria and chloroplasts have bacteria-like ribosomes.Both mitochondria and chloroplasts have a double membrane structure, i.e. an inner membrane and an outer membrane.Mitochondria and chloroplasts have a similar size as prokaryotic cells.In conclusion, the endosymbiotic theory is a well-supported theory and states that mitochondria and chloroplasts were once prokaryotes that were engulfed by an early eukaryote.

What is important to consider for plant maintenance?
There are various kinds of plants that grow in various climatic conditions. All these varieties require different conditions for their growth.
The conditions required for growth depend on the structure and chemical properties of the plants. The amount of sunlight, water and nutrition required differs in these physical and chemical and chemical properties.
The kind of soil required is also different according to the different kinds of plants. Soil availability depends on the geographical location. Therefore, to grow a particular kind of plant it's important to ensure that the soil required for its growth is available in that geographical location.
So, knowledge of all this is required to grow and maintain plants in a classroom.

Describe how cohesion and adhesion contribute to the upward movement of water through a plant.
Answer:
Cohesive forces makes molecules stick to become a mass. This force ensures that the water molecules stick together to form a mass. This enables water to fill the xylem which is a vascular bundle in plants.
Adhesion forces is what enables the water molecules which are now in form of a single mass to move upward in the columns of the cells for distribution of water and nutrients.

Las causas de los trastornos de la médula espinal son traumatismos, infecciones, bloqueo del aporte sanguíneo y compresión por un hueso fracturado o por un tumor.
Habitualmente, los músculos se debilitan o se paralizan, la sensibilidad es anormal o se pierde, y el control de la función de la vejiga y del intestino puede ser difícil.
El diagnóstico se basa en los síntomas y en los resultados de la exploración física y las pruebas de diagnóstico por la imagen, como la resonancia magnética nuclear.
Si es posible, se corrige la afección que causa el trastorno de la médula espinal.
Con frecuencia se necesita rehabilitación para recuperar el máximo de actividad posible.
La médula espinal es la vía principal de comunicación entre el cerebro y el resto del organismo. Es una estructura tubular, frágil y larga que parte de la base del encéfalo hacia abajo. La médula está protegida por los huesos de la espalda (vértebras) que forman la columna vertebral. Las vértebras están separadas y almohadilladas por discos de cartílago.

recent studies in bone research indicate that using ultrasound on a broken bone can decrease the healng time by 25% which of these are the most basic levels of organization involved when a bone heals
Answer:
This question is incomplete, it lacks options. The options are:
A. Cells and tissue
B. Cells and organ system
C. Organ system and organism
D. Tissue and organ system
The answer is A. Cells and tissue
Explanation:
A fractured/broken bone is capable of healing with time, although the process can be time-consuming. What occurs during the process is that blood clots develop around the area of the broken bone in order to protect the fracture and supply cells needed for the repair of the broken bone.
The aggregation of these cells form a tissue, which is the repair substance needed for the joining of the broken fragments. This repair substance is called CALLUS, which is initially made up of cartilage but later changes into bone tissue.
Hence, the most basic levels of organization involved when a bone heals are the CELLS and TISSUES.

Are climate change models accurate enough for costal city infrastructure planning?
Answer:
Yes
Explanation:
In the past climate change models were not accurate as they mostly understated the problems which resulted in more damages caused due to inaccurate preparations. However due to new technological innovations, there has been availability and improvement in the tools such as satellites.
This has led to an increase in the accuracy of the climate change models and subsequent planning of costal city infrastructures.
