Answer:
The correct answer is ''intermediate filaments.''
Explanation:
The intermediate filaments are made up of thick and resistant protein fibers, with an intermediate thickness between that of the microfilaments and that of the microtubules. They provide mechanical resistance to the cell, avoiding the rupture of the membranes of the cells subjected to stress. The macromolecules that make up the basal lamina interact specifically with specific receptor proteins present in the plasma membrane of the cell base, which in turn interact in the cytoplasm with filaments of the cell cytoskeleton. When the junction is associated with intermediate filaments, it is a hemidesmosome and when it is the actin cytoskeleton that is anchored in the junction, it is focal contacts. Hemidesmosomes are formed by a dense plate attached to the cell membrane, in which the intermediate filaments are inserted by joining connection proteins, such as desmoplakin, which connect to the cytoplasmic portion of the integral proteins of the cell membrane, which belong to the family of integrins.

Answer:
The sun / The UV lights that the sun emit
Explanation:
Dogwood and oak trees are two kinds of plants found in a forest. These trees and other forest plants get the energy they need for making food from Sun that is the solar energy which the plants use to produce sugar. Sun is the basic source that is used for photosynthesis.
What is the end product of photosynthesis ?Glucose is the end product of photosynthesis which is the ultimate source of energy for plants.
Photosynthesis usually takes place in 4 steps where the first step is the absorption of light where the light from sun is absorbed by stomata and the various reactions that take place in the light are called as the light reactions.
Transfer of light helps to electrons to excite and the excitation of electrons helps to make new products various phosophorylation reactions that is the production of ATP is taking place or the lysis of the product is taking place as well.

Annisa has a disorder or disease that the doctors found very difficult to diagnose.
Her primary symptom are that her muscles twitch without her control. Then
her metabolism stopped functioning.
Which body systems are working together in this scenario?
Answer:
Muscular and digestive systems.
Explanation:
Muscular and digestive systems are the body systems which are working together in this scenario because muscular system allows the movement of muscles and digestive system is the system where metabolism of the food occurs. If there is something wrong with the muscular system, the muscles can't perform their function properly while on the other hand, if the digestive system fails to work properly, the metabolism can't happen in our body and our body can be adversely affected.

Explanation:
Compare the concentration of connective tissue cells found in bone with the concentration of those found in blood.
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.

Complete the complementary strand of DNA, using the same symbols for phosphates (circles), sugars (pentagons), and bases. Mark the 5' and 3' direction of the strands,
Drag the appropriate labels to their respective targets. Terms can be used once, more than once, or not at all
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,
The original strand is the one at the left,The complementary strand is the one at the right.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.

porque los alimentos se oscurecen?(platanos, palta, manzana, papa, etc) respondan pls✋
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.

The primers you used in lab amplified 145 base pairs that were adjacent, but not included in the repeat. If you used a different primer that only amplified 130 base pairs adjacent to a 14 base pair repeat, and you had 4 repeats in your product, what was the size of your final PCR product?
186
214
158
200
172
Answer:
186
Explanation:
The Polymerase Chain Reaction (PCR) is a technique used in molecular biology to amplify small segments of DNA. This technique uses a pair of oligonucleotide sequences called 'primers' which bind to opposite strands of the heat-denatured DNA template in order to amplify this target DNA sequence. In this case, the DNA template is composed of a single unit of 130 base pairs (bp) and four repetitive units of 14 bp, so the final PCR product will have 186 bp >>> 130 bp + (14 bp x 4) = 130 + 56 = 186.
