How are viruses different from bacteria?
Answer:
Your correct answer is option A. Viruses contain only RNA
Explanation:
Viruses are smaller than any bacteria. In fact, the largest virus is actually way smaller than the smallest bacterium ever. All viruses have a protein coat and a core of genetic material of either RNA or DNA. Unlike bacteria, viruses can't survive without a host. They can only reproduce by attaching themselves to the cells. In most cases, they definitely reprogram the cells to make new viruses until the cells burst and die. In other cases, they turn normal cells into malignant or cancerous cells. Also unlike bacteria, most of the viruses do indeed cause disease and they are quite specific about the cells they attack.
The correct statement that highlights the difference between viruses and bacteria is "Viruses cannot survive outside a host." The correct option is B.
Viruses are obligate intracellular parasites, meaning they require a host cell to carry out their life cycle.
They do not possess the necessary cellular machinery or metabolic processes to replicate on their own.
Viruses invade host cells and hijack their cellular machinery to reproduce.
When a virus infects a host, it injects its genetic material into the host cell.
The viral genetic material then takes control of the host cell's machinery and directs it to produce new virus particles.
Viruses can have either RNA or DNA as their genetic material, but not both. Viruses have RNA genomes, while others have DNA genomes.Viruses are significantly smaller than bacteria. Viruses are typically composed of a nucleic acid core (either RNA or DNA) surrounded by a protein coat called a capsid. Viruses are not cells and do not have cellular structures. They are considered acellular particles because they lack the essential characteristics of living organisms.Thus, the correct option is B.

please I need help to answer these questions
Answer:
B. Directional Selection
Explanation:
By doing some research I found out what most of this means so let's do my favorite process, the process of elimination
A. Disruptive
Disruptive selection produces two or more species with two different traits nothing in the question says two different scorpions where formed one with big pinchers and another with big stingers no it just talks about them slowly forming big pinchers
C. Stabilizing
Stabilizing selection is when two species are produced with more similar traits nothing vastly different, I would consider them forming really big pinchers to be an extreme
How does osmoregulation take place in trout fish?
Answer:
The gills actively uptake salt from the environment by the use of mitochondria-rich cells. some marine fish, like sharks, have adopted a different, efficient mechanism to conserve water, osmoregulation. they retain urea in their blood in relatively higher concentration.

Why is there more nitrogen than oxygen in the air?
Answer:
Nitrogen is a stable gas and doesn't want to react to anything. When you breathe in air, you breathe in nitrogen along with oxygen. However, as oxygen gets absorbed into your body, since nitrogen is stable, you breathe it back out, leaving more nitrogen in the air.
From where do most producers get energy?
1. the sun
2. decomposers
3. consumers
4. other producers
Answer:
Energy is the ability to do work. ... The energy of the sun is first captured by producers (Figure below), organisms that can make their own food. Many producers make their own food through the process of photosynthesis. The "food" the producers make is the sugar, glucose.

Water conservation is an important issue for many reasons. One factor is that water conservation preserves and protects our natural resources. Conserving water means more water is available to serve additional water needs, as well as for wildlife and recreation. Water conservation practices can result in lower wastewater discharges which can mean an improvement in overall water quality. Conserving water diminishes our need to find or build new water sources, leaving them in reserve for our possible later use. Preservation does result in
A) lower algae levels
B) reduction in industry standards
C) slowing the building of new housing
D) lessening the need to find new water sources
Answer:
i believe the answer is D) lessening the need to find new water sources

The diagram provides an overview of how dialysis works. Using this model as an example, explain how the diyalysis machine performs the function that's normally performed by the kidneys
Answer:
The main job of a kidney is to filter toxins and waste products from the blood. In dialysis, the machine takes in blood from the artery and pumps it through a semipermeable membrane. This function is similar to that of the capillaries in the kidney. They allow waste products to filter from the kidneys. The waste excretes into a bag in a manner similar to how the bladder excretes urine from the body. The clean blood pumps back into the body and is carried back to the heart via a vein.

An earthquake originated in New York State. The P-wave travel time for this earthquake was recorded in the data table below for four widely separated seismic stations, A, B, C, and D If the first P-wave arrived at seismic station A at 10hrs:22min:30sec, what was the origin time for the earthquake?
The provided question is incomplete as it lacks the essential information to give answer. however, the complete question is attached as image.
Answer:
The correct answer is option : c. 10hrs: 14min: 10sec.
Explanation:
The question provides the following information to answer the question:
The P wave takes time to reach Seismic station A = 8 min:20 sec
P-wave arrived at seismic station A at : 10hrs:22min:30sec
So, the origin time of earthquake would be: 10hrs:22min:30sec - 8 min:20 sec = 10hrs: 14min: 10sec.
Thus, the correct answer is : 10hrs: 14min: 10sec.

Please help me asappp !! Now I need help :)))
Answer:
1. Glucose And Oxygen.
2. Transpiration is the process by which water is lost in the form of water vapour by evaporation from the surface of leaves and other serial parts of plant .
3. A. Cooling Effect : The water keeps on evaporating from the leaf surface during transpiration . The heat required for evaporation of water is obtained from the plant itself and thus, the plant cools itself when it is hot outside.
B. Transpiration Pull : As water evaporates from the leaf surface, the roots pull up more water from the soil to make up for the water loss during transpiration .As a result, important mineral salts are also brought along with the water. These salts are necessary for the growth of the plant .
4. Leaf Tendrils : Sweet Pea
Spines : Cactus
Scale Leaves : Onion
5. Pitcher Plant, Venus FlyTrap, Blodderwort
6. Normally plants propogate with the help of seeds contained in the fruits . But some new plants may also be produced from other part of the plant such as the roots, stems, and leaves . This type of reproduction is called vegetative propogation .
E.g. = Bryophyllum .
