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.

An iron cube has sides that measure 0. 5 meter. The cube is cooled from 95°C to 75°C. the change in volume of the iron cube is -9 × 10⁻⁵ m³.

The change in volume of the iron cube can be calculated using the formula: ΔV = 3αV₀ΔT, where ΔV is the change in volume, α is the coefficient of linear expansion, V₀ is the initial volume, and ΔT is the change in temperature.
Given:
α = 12 × 10⁻⁶ °C⁻¹ (coefficient of linear expansion for iron)
V₀ = 0.5³ = 0.125 m³ (initial volume of the cube)
ΔT = 75 - 95 = -20°C (change in temperature)
Plugging in the values into the formula:
ΔV = 3αV₀ΔT
ΔV = 3 × 12 × 10⁻⁶ °C⁻¹ × 0.125 m³ × (-20°C)
ΔV = -9 × 10⁻⁵ m³

The final branches of the interlobular arteries give rise to the afferent arterioles that carry blood to the nephrons.

The interlobular arteries are blood vessels that arise from the renal artery and enter the cortex at the boundary between the cortex and the renal pyramid. They are surrounded by a capillary network called the glomerulus. The capillaries in the glomerulus are uniquely structured, allowing them to filter the blood and eliminate waste. The interlobular arteries are divided into the afferent and efferent arterioles.Afferent arterioles are small blood vessels that carry blood from the interlobular arteries to the glomerulus. The afferent arteriole is wider than the efferent arteriole, and the pressure created by the blood entering the glomerulus causes the capillaries to filter the blood and remove waste.

This process results in the formation of urine that is transported to the renal pelvis through the collecting ducts of the nephrons. Afferent arterioles are important because they deliver blood to the glomerulus, which is responsible for filtering the blood and removing waste from the body. In addition, they help to regulate blood pressure and maintain homeostasis in the body.

Answer: Senses are necessary for behavior because behavior is a response to an organism's environment. Without senses, the organism would be unable to sense anything in the environment to react to. Senses tell an organism what to avoid and what to interact with; they guide the organism's decisions. Even organisms with very simple senses have some way to detect changes in the environment that need to be reacted to.

When there is an electronegativity gap between the two atoms of 0.0 to 0.4, a non-polar covalent bond is created.

A polar covalent bond forms when the electronegativity difference between the two atoms is larger than 0.4 but less than 1.8.

When the difference in electronegativity is at least 1.8, an ionic connection is created.

An example of epithelial to mesenchymal transition are PMCs ingressing in sea urchin and endoderm and mesoderm cells ingressing through the primitive streak in chick. So the correct answer is B and C.

Epithelial to mesenchymal transition (EMT) is a process by which epithelial cells undergo a transformation into mesenchymal cells, which are more migratory and invasive in nature. This process plays a crucial role in embryonic development, tissue repair, and cancer metastasis.

In option B, PMCs (Primary Mesenchyme Cells) ingressing in sea urchin undergo EMT as they transform from epithelial cells at the surface of the embryo into mesenchymal cells that migrate inward and contribute to the formation of the mesodermal structures.

In option C, endoderm and mesoderm cells ingressing through the primitive streak in chick also undergo EMT as they transition from an epithelial layer to a more mesenchymal phenotype, allowing them to migrate and differentiate into various tissue types during embryonic development.

Option A, epiboly in zebrafish, involves the movement of epithelial cells but does not necessarily involve EMT as it primarily occurs through intercalation and stretching rather than a transformation of cell types.

Option D, the invagination of the archenteron in sea urchin, does not involve EMT as it primarily involves changes in cell shape and movement rather than a transition from epithelial to mesenchymal cells.

The fluid mosaic model is the most widely accepted model for the arrangement of proteins and lipids in the cell membrane.

It proposes that the cell membrane consists of a fluid phospholipid bilayer in which proteins are embedded. This model was first suggested by Singer and Nicolson in 1972. The following are the experiments that support the fluid mosaic model:

Freeze fracture electron microscopy:

This technique was first used to observe the arrangement of proteins in the cell membrane. The cell membrane was frozen and then fractured along the plane of the membrane. The exposed fracture surface of the membrane was then examined under an electron microscope. The proteins were seen to be scattered throughout the membrane.

Fluidity of the membrane:

Lipids in the membrane are constantly moving and can exchange places with one another. This movement is due to the fact that the membrane is fluid. This fluidity was demonstrated by the use of lipids labeled with radioactive isotopes. It was found that lipids can move laterally within the plane of the membrane. Proteins in the membrane are also mobile, although to a lesser extent.

FRAP: Fluorescence recovery after photobleaching (FRAP) is a technique used to measure the mobility of proteins in the cell membrane. In this technique, a fluorescent molecule is attached to a protein of interest in the membrane. A small area of the membrane containing the labeled protein is then photobleached (i.e., the fluorescent molecules are destroyed). The recovery of fluorescence is then monitored as the labeled protein moves into the photobleached area.

The rate of recovery of fluorescence is a measure of the mobility of the protein in the membrane.

Initial conditions at points A and B (upland, top), and C and D (lowland, bottom) which represent the initial conditions that will result in one of the species being driven to extinction are options c. C and D, and option b. A and C.

The process in which an entire species of living organisms disappears from Earth is known as extinction. Extinction is the final stage of a long process of population decline that might occur over thousands or millions of years. Many species, especially single-celled organisms, have gone extinct during Earth's long history. Many other species have survived for millions of years but are currently endangered or vulnerable due to human activity.

The term "population" refers to a collection of individuals of the same species in a particular location. Members of a population compete for resources, including food, space, and water, as well as mates. These competitions can be fierce, resulting in population growth and decline depending on a variety of factors.

When a population is expanding or shrinking, the environment is the primary factor driving the changes in population size. The ability to model population growth and decline is critical to the field of ecology.
