How is the epithelium suited for the substances ?
Answers
Answer:
Epithelial tissue is composed of cells laid together in sheets with the cells tightly connected to one another. Epithelial layers are avascular, but innervated.
Epithelial cells have two surfaces that differ in both structure and function.
The epithelial cells are nourished by substances diffusing from blood vessels in the underlying connective tissue. One side of the epithelial cell is oriented towards the surface of the tissue, body cavity, or external environment and the other surface is joined to a basement membrane. The basement layer is non-cellular in nature and helps to cement the epithelial tissue to the underlying structures.
Your teacher places the following supplies on a table: water, hot plate, salt, beakers, food coloring, and test tubes. Using the supplies listed, how could you plan an investigation of how differences in temperature and salinity affect ocean currents? Include the following vocabulary in your explanation: salinity, density, temperature, wind, surface currents, deep currents. Make sure to include specific details and steps.
Answers
Answer:
Higher saline water is more dense that lower saline water
Explanation:
The ocean salinity varies with rainfall, run off from estuaries and the pattern of ocean current. In addition to this, higher temperature affects the kinetic movement of water as well as the salinity. The movement of the wind also contributes to the movement of water and the particles and solute distribution. The surface currents do not do much to mix the entire body of water and this is because this is from less dense areas. Deep currents factor in to mix just the heavier more dense layers.
In planning an experiment to test this one would do two experiments.
First: Heat 4 batches of water at different temperatures and color the different temperatures with different food coloring. Next layer the water carefully from hottest to coldest in a beaker and then from coldest to hottest in another beaker.
Second: Dissolve salt in 4 batches of water increasing the amount by half each time. Color each with different food colouring and layer the salty water from least salt to most salt in a beaker. Layer the water from most salt to least salt in another beaker.
Make observations:
The cooler water should be more dense and sink to the bottom while the saltier water should be more dense and sink to the bottom.

Predict the most likely outcome of culturing transformed E. coli in the presence of tetracycline.Justify your prediction.
Answers
Answer:
E.coli is a bacterium which is preffered for transformation due to its rapid growth and high efficiency of introduction of DNA molecules into cells.
Tetracycline is an antibiotic used to treat several infections such as cholera, plague, brucellosis, and malaria etcetra.
Plasmid is a small, extrachromosomal DNA molecule present in cell which is seprated from chromosomal DNA and have ability to replicate independently.
When a plasmid resistant to tetracycline and kanamycine is inserted into E.coli, the process is called transformation. E.coli might not be able to survive due to absence of plasmid but the transformed strains having antibiotic tetracycline and kanamycine will probably be able to survive it.
Hence, the culture of bacteria carrying plasmid will be able to survive only.
Maximum transformation to tetracycline achieved when cells were harvested from L broth at 5.0-6.0 cfu/ml , followed by washing twice in cold.
The susceptibility of E.coli strain to culturing transformation by plasmid DNA was examined and optimized.
TransformationCells grown within the presence of D - cycloserine ( Cyc ) rather than Neg Gram (N x) transformed better. The presence of 5 mm Mg2+ ions in washing and CaCl2 solutions stimulated transformation about 2-fold.
Optimal conditions for transformation included a pH range of seven. 25-7.75 and a cell-to-DNA ratio of about 1.6 . 10(8) cfu/ng plasmid DNA.
The frequency of transformation was highest when cells were exposed to 100 mM CaCl2 in 250 mm.
Composition[tex]\rm KCl + 5 mM \;MgCl2 + 5 mM \;Tris[/tex]
pH 7.6, before mixing with DNA
Therefore, the results of culturing transformed E.coli within the presence of tetracycline is justified.

Each spring when the worms reproduce, they have about 500 babies BUT only 100 of these 500 ever become old enough to reproduce. Question: What are the worms using to try to get as many of their offspring to survive? *
Answers
Answer:
If the environmental condition are suitable, the worms reproduce rapidly.
Explanation:
Environmental condition such as temperature, humidity, pH and texture of the soil has a great influence on the population of worms. If these environmental conditions are optimum, the worms reproduce rapidly and increase in population occurs. The population of worm increases because more worms start reproduction and reproduce baby worms. With the passage of time, these baby worms fully matured and start reproduction and increase the population of worms.
Answer: The keep themselves away from predation
Explanation:
The worms are mostly kept away from predators to make them survive. Some worms can be nocturnal while some are diurnal the nocturnal worm are inactive during the day keeping them away from predator but diurnal worms moves around during the day and it exposes them to predation they are been lost. The population the are survived to adult are the ones that have selective advantage of not being destroyed or feed on by preys. The Nocturnal are able to survive over a long time

The correct blanks are Intrusive, Slow, deposited, cementation, Regional, Contact, Foliation, volcanic, igneous, lithified, and Compaction.
Igneous rocks are a type of rock that forms from the solidification and crystallization of molten material, known as magma or lava.
Intrusive igneous rocks, also known as plutonic rocks, form when molten magma cools and solidifies beneath the Earth's surface.When molten magma or lava cools slowly, it provides sufficient time for the atoms and molecules within the molten material to arrange themselves in an orderly manner. The process of deposition refers to the settling or accumulation of sediments, which are fragments of rocks, minerals, organic matter, or other particles, onto a surface.Cementation is a process in which minerals in fluid form, often dissolved in groundwater, precipitate and crystallize within the pore spaces of sedimentary materials. During regional metamorphism, large volumes of rock are subjected to significant heat and pressure, typically deep within the Earth's crust. Contact metamorphism, also known as thermal metamorphism, occurs when a rock comes into direct contact with magma or an igneous intrusion.Foliation refers to the parallel alignment of minerals or the development of compositional layering within a metamorphic rock. Volcanic igneous rocks are classified as extrusive igneous rocks because they are formed from lava that has extruded onto the surface.The process of lithification involves the transformation of loose sediments into solid sedimentary rocks.Compaction is a key process in the lithification of sedimentary rocks. It takes place as layers of sediment accumulate over time, and the weight of the overlying sediments exerts pressure on the underlying layers.Thus, the correct blanks are Intrusive, Slow, deposited, cementation, Regional, Contact, Foliation, volcanic igneous, lithified, and Compaction.

Answers
Answer:
[tex]BMR_{women} = 1401.75[/tex]
Explanation:
According to Harris-Benedict equation the Basal metabolic rate of an organism can be calculated by using the following formula for both men and women -
[tex]BMR_{men} = 10 * W + 6.25 * H - ( 5 * A) + 5[/tex]
[tex]BMR_{women} = 10 * W + 6.25 * H - ( 5 * A) - 161[/tex]
Here, W is the weight in Kgs
H is the height in Cms
and A is the age in years
My weight is equal to [tex]65[/tex] Kgs
My height is equal to [tex]167.64[/tex] cms or [tex]5.5[/tex] feet
Gender - female and
Age is [tex]27[/tex] years
Substituting the given values in above equation, we get
[tex]BMR_{women} = 10 * 65 + 6.25 * 167.64 - ( 5 * 27) - 161\\[/tex]
[tex]BMR_{women} = 1401.75[/tex]
Sample Answer:
Brian is a 15-year-old boy who weighs 130 pounds and is 68 inches tall. He engages in moderate exercise.
Convert weight and height to the metric system.
Weight: 130 lbs. = 130 × 0.45 = 58.5 kg
Height: 68 in. = 68 × 2.54 = 172.72 cm
Calculate BMR.
For men, BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age in years) + 5 BMR = (10 × 58.5) + (6.25 × 172.72) − (5 × 15) + 5 = 1594.5 calories
Calculate daily calorie needs.
For moderate exercise, daily calories needed = BMR × 1.55 = 1594.5 × 1.55 = 2,471.475 calories

What is a “shared derived character”?
Answers
Answer:
A shared character is one that two lineages have in common, and a derived character is one that evolved in the lineage leading up to a clade and that sets members of that clade apart from other individuals.
Answer:
A shared character is one that two lineages have in common, and a derived character is one that evolved in the lineage leading up to a clade and that sets members of that clade apart from other individuals. Shared derived characters can be used to group organisms into clades. For example, amphibians, turtles, lizards, snakes, crocodiles, birds and mammals all have, or historically had, four limbs. If you look at a modern snake you might not see obvious limbs, but fossils show that ancient snakes did have limbs, and some modern snakes actually do retain rudimentary limbs. Four limbs is a shared derived character inherited from a common ancestor that helps set apart this particular clade of vertebrates.

What is the importance of DNA sequence?The genetic code determines the proteins manufactured by the cell. The proteins refers to the strands of amino acids. The DNA sequence of the genes determines the order of amino acids in a protein. This is the direct association between the traits and the genes.
It is the DNA, which carries all the instructions for the manufacturing of the proteins, these proteins determine the traits. DNA does not possess the tendency to leave the nucleus, thus mRNA copies the message of DNA and carries it to a ribosome. The mRNA is read by the tRNA that brings in the appropriate amino acid to produce the protein. This protein determine a trait.
Thus, DNA sequence determine a trait, as they provide instructions for the manufacturing of the proteins, these proteins further determine a trait.

Why do we need human dna
Answers
DNA. Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things.
All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information.
We need human DNA since it give us the long term info storage, which is needed
DNA contains instructions for development, survival, and reproduction. DNA sequences must be translated into signals to make proteins, which do most of our body's job.
What is human genome?DNA stores the instructions that are necessary for an organism to grow, maintain its existence, and reproduce itself. In order for these duties to be carried out, the sequences of DNA need to be transformed into messages that can be utilized in the production of proteins. Proteins are the complex molecules that are responsible for the majority of the work that is done in our bodies.
The human genome is comprised of all of the nucleic acid sequences that are found in humans. These sequences are stored as DNA within the 23 chromosome pairs that are found in the nucleus of cells, as well as in a tiny DNA molecule that is located within the mitochondria of each individual cell. In most cases, these are considered to be two distinct components: the nuclear genome and the mitochondrial genome.
