Answer:
Parasitism
Explanation:
First, let's define each term.
Mutualism: A symbiotic relationship where both organisms benefit
Commensalism: An association where one organism benefits, and the other is not harmed or benefited.
Neutralism: 2 organism interact but they have no effect on each other.
Parasitism: A symbiotic relationship where a parasite lives in or on another organism and harms the organism.
A dog and a tick are an example of parasitism. The tick lives on the dog and drinks the dog's blood. This is the food for the tick, so the tick is benefiting by gaining a food source. The dog can be harmed if the tick is carrying a disease, such as Lyme disease.

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.

Answer:
In desert plants, rate of water loss gets reduced due to the presence of cuticle.
Explanation:
Cuticle are protective, hydrophobic waxy covering produced by epidermal cells of leaves, young shoots and other aerial parts. It minimises the water loss through transpiration (with the help of stomata) and also reduces pathogen entry.

b. Spines
c. Scale Leaves
5. Give some names of insectivous plants.
6. Define Vegeative Propogation ?
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 .

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.
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.

to test for lipid is heat needed????????
Answer:
No
Explanation:
Place two spatulas of the food sample into a test tube or 1 cm3 if the sample is liquid.
Add 2 cm3 of ethanol to the tube. Cover the end of the tube and shake the tube vigorously.
Allow the contents to settle.
Pour the liquid from the top of the mixture into a test tube half-filled with water.
Record the level of the food and whether the water is cloudy or clear.
As you can see no heat is needed
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.

A DNA template is used to create an mRNA strand.
An mRNA template is used to create a DNA strand.
A DNA template is used to create a ribosome.
An mRNA template is used to create a tRNA strand.
Answer:
A DNA template is used to create an mRNA strand.
Explanation:
Transcription basically means a written or printed representation of something, if we connect that analogy to DNA, we are using the DNA as our template to write/create an mRNA strand out of it, basically transcribing the DNA.
What is the role of DNA template?
The DNA template is used by RNA polymerase to produce a strand of RNA with a nucleotide sequence that is the same as the coding strand for the production of functional RNA units and mRNA for making proteins.
How do you get mRNA from DNA?
mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II.

Explain photosynthesis in a paragraph.
Answer:
Photosynthesis is the synthesis of glucose from carbon dioxide and water in the presence of sunlight and chlorophyll with oxygen as a by-product it occurs in green plants,photosynthetic bacteria and some algae it is an anabolic(building) process and nearly all life depends on it it comprises many coordinated biochemical reactions that are necessary for the survival of the species it is divided into two phases 1 light reaction(Z-scheme) 2 dark reactions(Calvin cycle)
Explanation:
I hope this will help you:)
Answer:
Photosynthesis is the process through which autotrophs are bale to produce their own food. The Process is named so because photo means sun's light and synthesis means creating. It involves the Plants or other autotrophs absorbing the sun's light and also carbon dioxide released into the atmosphere by respiration. As a result of Photosynthesis, we obtain what is known as oxygen. This is, in fact, the biproduct of the process. Mainly, Photosynthesis occurs due to the presence of Chlorophyll which give leaves their green colour.
Key:
Autotrophs: Those who have the ability to produce their own food.
Biproduct: The extra result of a scientific equation.
Chlorophyll: a green pigment, present in all green plants and in cyanobacteria, etc.
