Answer:
Living cells
Explanation:
Viruses require living cells. Viruses aim to replicate themselves, and cells do exactly that. By injecting their DNA into a living cell, the cell will replicate the virus's DNA and infect other cells, spreading it more and more in the organism.
what is the inheritance of acquired characteristics? What scientist developed this mistaken idea?
The idea of it is that if an organism changes during life in order to adapt to its environment, those changes are passed on to its offspring. However, that isn't the case (proved by Darwin). This theory was made by Jean Baptiste Lamarck.
A scientist discovers a cell that has chloroplasts, cytoplasm, DNA, and a cell membrane. Which statement best describes how the cell could be classified?

Paragraph 3 describes the diagram at the top of this article. It demonstrates:
A: that energy flows in one direction beginning with light energy
B: the transportation of sugars into mitochondria
C: the Krebs Cycle
D: the Calvin Cycle
Photosynthesis involves a series of reactions including trapping of sunlight energy and the Calvin cycle through which plants make their food in the form of sugars.
What is metabolism?Metabolism refers to the sum of reactions that occur in a living organism which helps obtain energy and remove waste in order to sustain the life of an organism.
Different metabolic reactions take place in plants and animals.
In plants, energy is obtained from the sun and is used to drive photosynthesis.
The sugars made in photosynthesis are stored in roots, stem and tubers as well as in fruits.
The sugars can be broken down to produce energy in th mitochondria.
The Calvin cycle is the process that plants use to convert carbon dioxide and water to sugars
The Krebs cycle is a cycle which produces molecules which are used to produce energy in the mitochondria.
Therefore, since the diagram is not attached, the process shown can be understood from the explanation of each process in photosynthesis and metabolism.

A piece of dna that is used to carry a gene of interest into a cell is known as what?.
Plasmid carries a gene into a cell
A piece of DNA that is used to carry a gene of interest into a cell is known as Vector. This is because it is a vehicle that significantly carries foreign DNA molecules into the host cell.
What is Gene?Gene may be defined as a stretch of DNA that has genetic information. It is the nucleotide sequence that has the ability to produce a functional protein or enzyme.
According to the context of this question, a vector is commonly used in recombinant DNA technology. It is a double-stranded, circular extrachromosomal DNA that is separated or detached from the genomic DNA.
It has quite a difference with plasmid. The Plasmid is generally an extrachromosomal element of the bacterial cell.
Therefore, a vector is a piece of DNA that is used to carry a gene of interest into a cell.

what are the differences between plant cell and animal cell
Explanation:
Plant cell:
It is found only in plants.
It consists of cell wall.
Animal cell:
It is found only in animals.
It does not consists of cell wall.
Answer:
The main structural differences between plant and animal cells are the additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles.
Chloroplasts
In animal cells, the mitochondria produces the majority of the cells energy from food. Plant cells use sunlight as their energy source; the sunlight must be converted into energy in a process called photosynthesis. Chloroplasts are perform this function. The energy conversion in plants is a complex set of reactions similar to those performed by mitochondria in animals
The Cell Wall
Another structural difference between in plant cells is the presence of a rigid cell wall surrounding the cell membrane. The tough wall gives added stability and protection to the plant cell. If you think about it, most animal cells are inside an organism that has either an exoskeleton or an endoskeleton, built in structure. Plants don't have a skeleton of any kind so the cells have to perform this.
Vacuoles
Vacuoles are large, liquid-filled organelles found only in plant cells. Vacuoles can occupy up to 90% of a cell's volume and have a single membrane. Their main function is as a space-filler in the cell, but they can also fill digestive functions and their interiors can be used as storage for nutrients.
Both plant and animal cells comprise membrane-bound organelles, such as endoplasmic reticulum, mitochondria, the nucleus, Golgi apparatus, peroxisomes, lysosomes. They also have similar membranes, such as cytoskeletal elements and cytosol. The plant cell can also be larger than the animal cell. The normal range of the animal cell varies from about 10 – 30 micrometres and that of plant cell range between 10 – 100 micrometres.

What is the difference between force and net force?
Don't copied from goo-gle
Force
- Force is defined as the act of pushing or pulling of an object. It can influence and alter the motion of an object.
Net Force
- Unlike Force which only defines a push or pull, Net Force is the combination of all forces acting on an object. The Net Force can be computed through Newton's Second Law, F=ma.

What are invasive species? how do they impact the ecosystem
Answer:
disorder in the ecosystem
Explanation:
Invasive species are organisms from different ecosystems that somehow find their way to a different one. The ecosystem that they arrive in cannot be prepared to receive them and the invasive species, these species may not have predators or characteristics that help them to feed or reproduce quickly. This causes a disorder in the ecosystem that can wipe out entire species and if a species disappears in a chain many others will be affected.
