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 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.

What are ocean waves?Ocean waves are the result of the interaction between the ocean and the wind. They are the most visible and powerful manifestations of the Earth's oceans. Ocean waves vary in size, shape, and speed, depending on the wind's strength, duration, and direction. They can range from small ripples to massive swells and can travel thousands of miles before breaking on shorelines.
The energy of ocean waves is harnessed for various purposes, such as surfing, fishing, and generating electricity through wave energy converters. However, ocean waves can also be destructive, causing erosion and flooding in coastal areas during storms.
Ocean waves play a crucial role in regulating the Earth's climate by transferring heat and energy from the tropics to the poles. They also help distribute nutrients and oxygen to marine life, and their movement influences the ocean's circulation patterns.

Based on your knowledge of energy flow and light absorption, which color(s) of light will provide energy for photosynthesis? (select all that apply) question 2 options: red orange green blue violet
Answer:
RED and BLUE
Explanation:
Special pigments in chloroplasts of plant cells absorb the energy of certain wavelengths of light, causing a molecular chain reaction known as the light-dependent reactions of photosynthesis. The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm).
Red and blue as the best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm).
Which colors of light are most absorbed for energy during photosynthesis?Chlorophyll is the pigment responsible for photosynthesis. It absorbs most energy from wavelengths of violet-blue and orange-red light.
The chlorophyll pigments mainly absorb blue and red light. Maximum absorption is in blue light but maximum photosynthesis occurs in red light
Thus, the answer is red and blue.

One major difference between viruses and other cells is that viral particles have nucleic acid located within a capsid.
Structure of a virusViruses are made up essentially of ribonucleic or deoxyribonucleic acids enclosed in a proteinous shell known as capsids.
This is unlike other cells in which their nucleic acids either lie freely within the cytoplasm of their cells or are enclosed in a double membrane structure known as the nucleus.

How would the inherited traits discussed in this lesson be influenced if those alleles were on a s3x chromosome? Would the probability of inheritance change?
(an example"traits discussed" is wired haired dogs and smooth coated dogs)
I'd really appreciate the help! :D
The discussed inherited traits would not be influenced if these alleles were on an s3x chromosome, the probability of inheritance would not change.
To understand the answer, we need to know about s3x chromosomes
What are s3x chromosomes?Females have two identical chromosomes (XX), while males have an X chromosome and a smaller chromosome called a Y. Human males are heterogametic with two different s3x chromosomes (XY). Human females are the gametic s3x (XX).
With this information, we can conclude that the discussed inherited traits would not be influenced if these alleles were on an s3x chromosome, the probability of inheritance would not change.

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.
