Answer: An invasive species is the one which compete for resources with the native species.

Explanation:

Wild Parsnip is an invasive species of plant in Europe and Asia. It grows on the roadside and the seeds of the plant disperse very easily by wind and water agents. It spreads easily and compete with native species for resources like soil nutrients, water, and others. It produces a chemical that causes rash in the human skin and the human skin becomes sensitive to sunlight resulting in development of blisters and rashes on the skin.

Answer:

came from Europe and Asia

invaded the entire state of Wisconsin

Answer: Periodic table of the elements

The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends.

About the question:

You will find the completed strand in the attached files

Answer and Explanation:

First, we need to recognize each strand, the original one and the complementary one. We can recognize the original strand because bases are already given. So,

Now we need to recognize and pair the bases. Names are written with their letters.

Nitrogenated bases that form nucleic acids correspond to purines and pyrimidines. Adenine and guanine derive from purines, while Thymine and Citocine derive from Pyrimidines.  

In the DNA molecule, Adenine (Purine) forms pairs with Timine (Pyrimidine), while Guanine (Purin) pairs with Cytosine. Two hydrogen bonds join the A-T pair, and three hydrogen bonds join the G-C.

Once we drag the base labels to their targets, we need to recognize each of the strain extremes.

One of the extremes has a phosphate group, which is named 5´. The other extreme has a hydroxyl OH named 3´. Both of them are readen in the 5´to 3´ direction. The polymerase enzyme reads the original strand in 5´ to 3´ mode, and the molecule lecture goes from 3´to 5´.

So, by looking at the labels, we will recognize the phosphate extreme and the hydroxyl one. We will place in the superior extreme of the original strain the phosphate group 5´ and in the other extreme the OH 3´. These positions will give us the direction reflected by the arrow. The complementary strand will have the same extreme labels but in opposite places. So first we will place the OH 3´ label in the superior extreme, and the phosphate 5´label in the inferior extreme, defining the direction reflected by the arrow.

Answer:

A change in the integrin proteins from the cell's surface.

Explanation:

Integrin proteins' principal function is to attach the cell to the basal lamina. Also, they transmit signals from the extracellular matrix to the interior of the cell. A change in the integrin could result in loss of connection between the mutated cell and the basal lamina.

Cadherin proteins connect one cell to another. A change in these proteins will not result in the loss of connection between the metastatic tumor cell and its extracellular matrix. It most likely will affect the communication and adhesion of cells.

A change in connexins will disrupt the communication between cells but not the connection to the lamina basal. Connexins are transmembrane proteins that connect one cell to another with gap junctions that allow the passage of different components from cell to cell.

Answer:

C. Uterus

Explanation:

Uterus is the female reproductive system.

The female reproductive system serves a number of purposes. It aids in sexual reproduction in addition to enabling sexual activity.

You make eggs using your ovaries. During ovulation, these eggs are subsequently moved to your fallopian tube where sperm fertilization may take place. The fertilized egg is then transferred to your uterus, where the lining of the uterus has expanded due to the typical hormones produced during your menstrual cycle, also known as your reproductive cycle.

The fertilized egg can implant into the thicker uterine lining once it's within your uterus and continue to grow there. Your menstrual period causes the uterine lining to shed if implantation doesn't occur.

Therefore, Uterus is the female reproductive system.

Answer: CONNECTIVE TISSUE is the most abundant tissue in the body which are widely separated from each other and intercellular substance (matrix) is present in considerably larger amounts. The principal cell of connective tissue are fibroblasts which makes fibres found in almost all connectiv tissues. Some are solid and strong (bone), while others are fluid and flexible( blood).

Explanation:

Connective tissues usually contain fibres present in the matrix which may be of semisolid jelly-like consistency or dense and rigid, depending upon the position and function of the tissue. There are three main types of connective tissue which include:

--> Loose connective tissue

--> Dense connective tissue and

--> specialised connective tissue.

The bone and the blood are considered to be an example of specialised connective tissue. This is so because they both contain a number of different tissues with specialized cells and unique ground substances.

The BONE consists of osteoblasts, osteocytes, and osteoclasts. It is considered to be a specialised connective tissue because the bone cells are surrounded by a matrix of collagen fibres strengthened by inorganic salts, especially calcium and phosphate.

The BLOOD consists of red blood cells, white blood cells, platelets. It is considered to be a specialised connective tissue because the blood cells are surrounded by fluid matrix known as plasma and connecta with other cells through its transport functions.

In COMPARING the concentration of connective tissue cells or bone and blood, the connective tissue cells of bone comsist of fibre and collagen which makes it dense and rigid while the connective tissue cells of blood does not contain any fibre, therefore it's flexible.

Answer:

D. A nitrogen base has been added to the DNA molecule.  

Explanation:

You can see that the sequence for the nitrogen bases are in the exact same order after the exposure, this rules out A.  You can count how many bases there are, 7 before and 8 after so it cannot be B. Lastly, given that they are in the same order as were before and that a base has been added, you can see that no bases were replaced (so not C) and that D is your answer.  

Answer:

Una enzima es una sustancia, generalmente una proteína, en la célula de un organismo que acelera las reacciones químicas.

Durante el pardeamiento enzimático, una enzima llamada fenolasa y otro compuesto orgánico que se encuentra en las células de la fruta llamados fenoles pasan por una reacción de oxidación cuando se exponen al oxígeno. La fenolasa regula la reacción, convirtiendo los fenoles en melanina.

Por lo general, las enzimas de la fruta están encerradas en tejido. Las enzimas están metidas en sus células, trabajando para madurar la fruta. Pero cuando esas células se descomponen, ya sea por una causa externa como si alguien muerde o corta la fruta o por causas naturales como el envejecimiento, las enzimas se liberan y entran en contacto con el oxígeno, lo que desencadena la reacción química y hace que la fruta se vuelva marrón.

Answer:

The correct answer is - tend to lose water by osmosis since their internal salt concentration is lower than that of seawater.

Explanation:

In freshwater fishes, the body of fishes has a higher salt concentration inside their body than the surrounding water, water enters through the osmosis process. Without any active regulation of this process, fishes would swell and get bigger and bigger. They have specialized cells called chloride cells in gills to take ions from water as they do not have kidneys.

In contrast, the marine fishes have a lower salt concentration in their body than surrounding water of sea or ocean and they lose water continuously and to compensate for this they need to drink water regularly.

Answer:

strike-slip is when the blocks have mostly moved horizontally, normal is when a dip-slip fault in which the block above the fault has moved downward relative to the block below, and thrust is when the hanging wall moves up relative to the footwall.

There are three faults. Normal faults originate from the divergent boundary. Reverse faults originate from the convergent boundary. Strike-slip fault originate from transforming boundary.

We can differenciate three types of faults,

I. Divergent:

This boundary occurs when two plates separate and molten material rises from the mantle creating a new crust.

The hot material creates a new seabed between the separating plates, expanding the sea bottom.

II. Convergent.

Collision area between two plates. Two oceanic plates might collide, or one oceanic plate with a continental one.

In this last case, the oceanic crust sinks under the continental plate, and magma rises to the surface by crevices.

The thicker and older plate subduces under the other plate.

III. Transforming.

The plates slide laterally with each other, and they are usually called faults.

It is associated, in general, with the oceanic ridge, although it might also occur in the continental plate.

No rocky material is either destroyed or formed.

When the plates move and produce a displacement of one transforming limits from side to side, earthquakes occur.

The movement breaks the crust and originates pronounced fractures.
