Answer:
This question lacks options, the options are:
A. They may act to turn on gene transcription.
B. They may act to turn off gene transcription.
C. They may become added to DNA, and then be transcribed.
D. They may remove a gene from DNA.
E. They may alter the nucleotide sequence in a gene.
Options A and B are the answers.
Explanation:
Prokaryotes regulate gene expression at the transcriptional level. Gene expression is the process whereby living organisms synthesize useful products such as protein from a gene. Prokaryotes such as bacteria control the expression of their genes via proteins that bind to DNA called REGULATORY PROTEINS.
These regulatory proteins also known as TRANSCRIPTION FACTORS, act to regulate genes by binding DNA. The binding of DNA either prevents or promote the binding of RNA polymerase in order for transcription to occur.
- Regulatory proteins which may act to inhibit transcription of DNA by turning off gene are called REPRESSORS.
- Regulatory proteins which may act to promote transcription of DNA by turning on gene are called ACTIVATORS.

Explain surface runoff. HELP PLSSSSSSS
Explanation: Surface runoff is water, from rain, snowmelt, or other sources, that flows over the land surface, and is a major component of the water cycle. Runoff that occurs on surfaces before reaching a channel is also called overland flow. A land area which produces runoff draining to a common point is called a watershed
Explanation:
surface runoff also called soil erosion is the washing away of top soil by the actions of moving water after rainfall. It occurs when the surface of soil is exposed to direct rainfall.

Healthy ecosystems depend on–
Healthy ecosystems depend on a variety of factors working together in balance.
Some key factors include:
1. Biodiversity: Healthy ecosystems have a rich variety of species, including plants, animals, and microorganisms.
2. Nutrient Cycling: Ecosystems rely on the cycling of nutrients, such as carbon, nitrogen, and phosphorus, to support the growth and survival of organisms.
3. Energy Flow: Ecosystems depend on the flow of energy from the sun. Producers, such as plants and algae, convert solar energy into chemical energy through photosynthesis.
4. Interactions and Relationships: Healthy ecosystems are characterized by complex interactions and relationships among organisms.

Which option best explains how consumers like omnivores, herbivores, and carnivores are dependent on other living things for food?
1)Plants make their own food using sunlight. Herbivores eat plants for food. Omnivores eat plants and animals for food. Carnivores eat animals for food.
2)The flow of food starts with sunlight. Plants make food through photosynthesis. Herbivores eat omnivores for food. Omnivores eat plants for food. Carnivores use sunlight to make their own food.
3)Energy flow starts with plants. Plants make their own energy. Omnivores get their energy by eating plants. Herbivores eat carnivores for food. Carnivores eat plants for food.
4)Herbivores make their own energy using sunlight. Plants eat herbivores for food. Omnivores eat animals for food. Carnivores eat herbivores for food.

A fire sits 72 feet from the abs of 125 foot tall building. Find the angle of Evel at ion from the fire to the top of the building
Answer:
60°
Explanation:
From the attachment,
Opposite side of the triangle= 125 feet
Adjacent=72 feet
Angle of elevation= (θ)
From trigonometry,
Tan (θ)= Opposite side /Adjacent adjacent
Where
(θ)=angle of elevation
If we substitute to above expresion we have
tan(θ)= 125/72
tan(θ)= 1.736
Tan^-1(1.736)=60°
θ= 60°
Hence, the angle of Evel at ion from the fire to the top of the building is 60°

A protein channel in a hydrogen ion pump is shown below. What would happen if the concentration of H+ ions were higher inside the mitochondrion than outside the mitochondrion when the channel opened?
Answer:
The H+ ions moves outside.
Explanation:
The H+ ions moves outside the mitochondria of the cell if the concentration of H ions were higher inside the mitochondrion than outside environment of the mitochondrion in order to equalize the pH or H+ ions concentration of both inner side of mitochondria and outer side environment. This movement of H+ ions from a region of higher concentration to the region of lower through a semi-permeable membrane is known as osmosis which has a positive effect on the cell as well as organelles of the cell.

immune system.
vascular system.
reproductive system.
root system.
Answer:
B
Explanation:
In this situation, a plant's response system is working in conjunction with the vascular system. Therefore, option B is correct.
What is a vascular system?The complex network of conducting tissues known as the plant vascular system connects all organs and carries water, nutrients, organic compounds, and different signaling molecules throughout the body of the plant. The primary transport systems of plants, xylem and phloem, make up vascular tissue. They often coexist in vascular bundles that cross the roots, stems, and leaves of all plant organs. Water and dissolved ions are moved upward through the plant through the xylem, starting at the roots.
Clubmosses, horsetails, ferns, gymnosperms (including conifers), and angiosperms are examples of vascular plants (flowering plants). The group is known by its scientific names, Tracheophyta, and Tracheobionta.

Use the student's hypothesis to predict which parachute, A, B or C, will hit the ground first. Give a reason for your answer?
Answer:
The heavier will come first to hit the ground.
Explanation:
That parachute will come faster and hit the ground first which has more weight than other parachutes because the heavier objects comes to the earth at faster rate as compared to light objects. So if all the three parachute has same size and shape but difference in weight than the heavier one comes to the ground first as compared to other two parachutes.

Infectious diseases have an easier time spreading now than they did several hundred years ago. What about society has changed that makes this possible? Describe at least TWO reasons.
Answer:
see below :)
Explanation:
Infectious are more easily spread nowadays becuse of an increased population. The more the population increases, the bigger the advantage an infectious disease has. As of right now, because everyone is wearing masks, their immune systems are being weakened. Another reason for this is because of the increase in chemicals in our foods, which are now being transferred to our bodies. All of the medications people are taking also have an affect on the spread of disease; it gives diseases a chance to mutate.

why do we need new body cells
Answer:
When we are adults many cells mature and become specialised for their particular job in the body. So they don't make copies of themselves (reproduce) so often. But some cells, such as skin cells or blood cells are dividing al the time. When cells become damaged or die the body makes new cells to replace them.
