Explanation:
DNA is negatively charged, therefore, when an electric current is applied to the gel, DNA will migrate towards the positively charged electrode, Shorter strands of DNA move more quickly through the gel than longer strands resulting the fragments being arranged in order of size.

If you were to eat a strawberry, what types of organelles would you eat from the strawberry cells
Some fruits are especially well suited for DNA extractions due to their multiple sets of chromosomes. Strawberries are octoploid, which means they have eight copies of each chromosome. In comparison, human cells are diploid, which means they contain two copies of each chromosome.
which organelle does the skeletal system connect to and why?
Answer:
Muscles connect to your skeleton and they contract and move the skeleton along. Your skeletal system is made up of cartilage and calcified bone that work together. They help the process of movement happen in a smoother manner. The calcified bones of your skeleton also work with the circulatory system.
Answer:
Organelles of a skeletal muscle cell contain the same organelles as other animal cells, with the addition of myofibrils. Muscle fibers within the skeletal cell are known as myofibers. These organelles allow skeletal muscle cells to contract. Skeletal muscle cells do contain more mitochondria than other cells, because muscle cells require more energy and must convert more glucose. Skeletal muscle cells also differ from other cells because of the myofilaments within the myofibrils. Within these filaments are proteins known as myosin and actin. The special filaments enable the skeletal muscles to contract. The myofibrils within skeletal muscle cells are divided into units known as sarcomeres, which are the units of skeletal muscle cell contraction.
Which process releases energy , photosynthesis or cellular respiration ?
Answer:
In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.
20. Dominant inheritance: Pattern of inheritance in which, when an individual receives contradictory
alleles for a trait, only the dominant one is

Which is the relationship between photosynthesis and cellular respiration?
Cellular respiration makes the glucose that is needed by photosynthesis
Photosynthesis makes the glucose that is broken down by cellular respiration

Two rough black guinea pigs when bred together have two offspring. One of them is rough white and the other is smooth black. What are the genotypes of these parents?
Parent 1 __________ Parent 2 ___________
Answer:
Parent 1 = RrBb
Parent 2 = RrBb
Explanation:
This question involves two genes in guinea pigs. The allele for rough coat (R) is dominant to smooth coat (r), and the allele for black coat (B) is dominant to white coat (b).
According to this question, two rough black guinea pigs when bred together produced two offsprings. One of the offsprings is rough white (R_bb) and the other is smooth black (rrB_). This means that, to produce such offsprings, the parents must be both heterozygous for both genes (RrBb). Please find the punnet square for this cross attached

explanation of gender in female
Answer:
Female means a women gender.
Explanation:
this is the correct answer you want .
Answer:
First off, chromosomes are thread like structures found in the nucleus of a cell containing genes, which determine a certain characteristic, and DNA which is the chemical that is the basic unit of inheritance.
All human cells ( excluding people who has cell abnormalities etc. ) contain 46 chromosomes. However there's this one pair of chromosomes called the sex chromosomes ( X and Y chromosome ) which defines whether the person is a make or female.
A male will have XY chromosomes, but a female will have XX chromosomes. That's how you differentiate.

predicting metabolic state in a seed requires sun, heat exposure, root establishment 2 absorb nutrients from the sun, & soil agree ability.. because all 3 need eachother to produce necessary chlorophyll to feed the plant...
Are All cells in a plant are of the same type.
answer:
the answer you re looking for is no
explanation:
because some cells in plants make meristematic tissue while others make permanent tissue!
for example, here are a couple of different types of cells in plants would be
parenchyma cells
collenchyma cells
xylem cells
phloem cells
epidermal cells
chlorenchyma cells
sclerenchyma cells

Why we get tired when we wake up from sleep immediately??
Answer:
Sleep inertia, which is a normal part of the waking process. Your brain typically doesn't instantly wake up after sleeping. It transitions gradually to a wakeful state. During this transition period, you may feel groggy or disoriented.
Answer:
is due to sleep inertia... your body may be awake but brain is not active yet

Evaluate the pros and cons of using an NPK fertilizer, a natural compost, and lime on a field with substantial amounts of clay and humus and with a low pH of 3, which is to be planted with a legume crop.
Answer:
Leaching of nutrients occur.
Explanation:
NPK fertilizers are applied to the field all over the world because it has a good effect on the growth and development of plants but it has also some environmental effects such as leaching which pollutes water bodies whereas natural compost is good for the plants as well as for the soil organisms but its breakdown is very slow and it is not readily available to the plants. Lime is also very good for the soil having low pH because lime is basic in nature and it increases the pH of the soil.
How do trees remove carbon from the atmosphere ?
Answer:
Trees and including all plants use the energy of sunlight and including the process of photosynthesis they take with the carbon dioxide or know as ( CO2) from the air and water from the ground. In this process of converting this into wood they can relase oxygen into the air.
I hope this helps you .

b. Posterior column
c. Located to the periphery of the spinal cord
d. Gracile fasciculus
e. Anterior spinocerebellar tract
f. Medial vestibulospinal tract
g. Marked by low myelination
h. Functions to integrate arriving electrical signals
i. Contains somas, synapses, and dendrites
The grey matter includes neural cells, dendrites, and axon terminals, whilst white count number consists of axons and myelin.
How can you inform the difference between grey and white remember and the brain?The white rely takes place in both the brain and spinal wire. but, gray be counted is a large part of the mind. the main difference among white rely and grey rely is that white count number mainly incorporates myelinated axons and gray matter specifically consists of cells, axon terminals, and dendrites.
What is the grey and white remember of the spine?Gray be counted is a grey area across the critical anxious machine of the CNS. A combination of neuron bodies of interneurons and motor neurons and neuroglia. Synapses from grey matter. White depend does not incorporate the bodies of neuron cells however millions of axons and neuroglia.

pls what is a strain in microbiology
[tex] \huge \sf{strain}[/tex]
A strain is a genetic variant or subtype of a microorganism (e.g., a virus, bacterium or fungus). Microbial strains can also be differentiated by their genetic makeup using metagenomic methods to maximize resolution within species.
Type strains are descendants of the original isolates used in species and subspecies descriptions, as defined by the Bacteriological Code [14], that exhibit all of the relevant phenotypic and genotypic properties cited in the original published taxonomic circumscription
