Answer:

Option D, When the oil has already started to break down

Explanation:

When the oil breaks down, there are high chances that it can get absorbed at the surface of beaches consisting of sand, gravel, or cobble which cannot be cleaned otherwise. In such scenarios adsorbents are placed manually to soak the oil spilled on beach. Mostly shorelines are cleaned using these manual processes, otherwise inner oil spills are cleaned by machines only.

Hence, option D is the correct answer.

Lipids, specifically phospholipids, serve as the component of the cell membrane, store energy, and act as steroids in the body.

The substance that stores energy, serves as a steroid, and makes up much of the cell membrane is lipids. Lipids are a type of organic molecule that is found in living organisms. They play a vital role in the structure and function of cells. In cell membranes, phospholipids create a barrier that protects the cell and regulates what enters and exits. In addition, lipids serve as a major source of stored energy in the body. Certain lipids also serve as steroids which regulate body functions.

A broken nose can involve the nasal bones, which form the bridge of the nose; the delicate ethmoid bones that contribute to the nasal cavity; the maxilla or upper jaw; and the zygomatic or cheekbone.

When a fracture conflicts with the nose and the nasal cavity, it can affect multiple bones. The nasal bones, which form the bridge, are most often involved in a break. Additionally, the ethmoid bones—small, delicate bones behind the nasal bones which help form the nasal cavity—may also be involved. The maxilla, the bone that forms the upper jaw and part of the lower orbital and nasal cavity, and the zygomatic bone (cheekbone), which extends towards the nasal bone, could also potentially be involved in a severe break.

Answer: Option B

Explanation:

Proteins can be defined as the large and complex molecules which are made of numerous smaller units of amino acids, each amino acid combines to one another in long chains to form a protein molecule. They provide structure to the body thus known as building blocks of the body. They helps in regulating the body process like enzyme catalysis, breaking down of food, transporting all the essential molecules throughout the body, hormone regulation, movement of muscles, message signaling and many others.

Insulating the body is the primary function of Fats not proteins.

Therefore, the correct answer is "Option B".

Cell structure, communication, and acts as enzymes are the functions of protein but insulating the body is not a function of protein, hence option B is correct.

The form and internal organization of cells, the production of products and the removal of waste, as well as normal maintenance, are all carried out by proteins.

Each protein is uniquely suited for its intended use. Only 20 different combinations of amino acids may be used to make any protein in the human body. Antibodies, contractile proteins, enzymes, hormone proteins, structural proteins, and transport proteins are the seven different categories of proteins.

Explanation:

You have seen that at temperature 20°, around 50 aliens were thin. At 25°, roughly 70 aliens were thin. Moreover, at 30°, nearly 88 aliens were thin. The take-home feature is that the greater the temperature, the larger number of aliens are suspected to be thin. So at 35°, we would suspect a higher number of aliens to be weaker than the 88 who are thin at 30°.

The answers would be:

Neptune - It is sometimes farther from the sun than Pluto.

Uranus - It has seasons that last 20 years

Saturn - It has the Shepherd Moons.

Jupiter - It is the largest gas giant

Here is more about the planets:

Neptune becomes farther from the sun than Pluto at times because of the orbit of Pluto. The orbit of Pluto is very elliptical, so at times it crosses the inside the orbit of Neptune. For example, from 1979 to 1999, Neptune was further from the Sun than Pluto.

Each season in Uranus lasts 20-21 years mainly because of its orientation. Unlike other planets, Uranus spins on its side and has a tilt of 93 degrees. A day in Uranus is about 17 Earth hours. During the winter-summer seasons, only one side of Uranus is exposed to the sun, and will not see daylight for 21 years.

Saturn has what we call Shepherd moons. They are called as such because they act like shepherds. They keep the dust and debris that form the rings of Saturn in place. This is also why the edges of the rings of Saturn are well-defined.

Lastly, Jupiter is the largest has giant in our Solar System and is also known as the largest planet in our solar system. It has a diameter of approximately, 143,000 km. Jupiter is made up of mostly Helium and Hydrogen. It has more than 50 moons.

The features that might affect how leaves process and perform rate of photosynthesis is determined by its surface area, chlorophyll and stomata.

The surface area of the leaf influences its performance to photosynthesis through the amount of light captured by it which is needed for photosynthesis to occur. As well chlorophyll which enables the leaf to absorb light and be processed. Lastly, stomata which is responsible for carbon dioxide and gas exchange.

Various features such as leaf size, age, thickness, orientation, and pigmentation can significantly impact the rate of photosynthesis in plants.

Several features or variables of plant leaves can affect the rate of photosynthesis. These include:

1. Leaf surface area: Larger leaves provide more surface area for gas exchange and light absorption, potentially increasing photosynthetic rates.

2. Leaf age: Younger leaves often have higher rates of photosynthesis compared to older leaves due to their higher chlorophyll content and metabolic activity.

3. Leaf thickness: Thicker leaves may have more mesophyll cells and chloroplasts, enhancing photosynthetic capacity.

4. Leaf orientation: Leaves positioned to receive optimal sunlight will have higher rates of photosynthesis compared to shaded leaves.

5. Leaf pigmentation: The presence and abundance of chlorophyll, carotenoids, and other pigments influence light absorption and photosynthetic efficiency.

Final answer:

The weaving of pastry on top of food, especially pies, is known as a lattice. It combines function and beauty, allowing steam to escape and giving a golden brown finish to baked goods.

Explanation:

The criss-crossing strips of pastry on top of food is called a lattice. This technique is often used in baking to create a visually appealing and edible top layer on pies and other pastries. The lattice is essentially a woven pattern created by interlacing long strips of pastry dough over and under each other. One famous lattice-topped pastry is the apple pie, a staple in American cuisine. The lattice top allows steam to escape during baking, which helps to prevent the pastry from becoming soggy. The lattice provides a lovely contrast of texture and color when baked until golden brown.

Alfred Wegener used rock and fossil evidence to support his hypothesis of continental movement by finding similarities in continent shapes, fossils, mountain ranges, and paleoclimate.

Alfred Wegener used rock and fossil evidence to support his hypothesis of continental movement in several ways:

With this evidence, Wegener proposed that all continents were once together in a single supercontinent called Pangea.

In a phylogenetic tree, Species 1 and Species 2 are more closely related to each other than to Species 3 if they share a more recent common ancestor. The tree is continually revised based on new molecular and morphological evidence. The three major domains of life are Archaea, Bacteria, and Eukaryota.

To assess the relationship between two phyla according to a phylogenetic tree, one must look at the point where the branches representing the phyla connect to a common ancestor. The closer the common ancestor is to the terminal ends of the branches (where the living species reside), the more recently these two groups have diverged from one another, indicating that they are more closely related. In a phylogenetic tree, Species 1 and Species 2 share a more recent common ancestor with each other than with Species 3, which is why Species 1 and 2 are more closely related to each other. The tree is a hypothesis that reflects evolutionary history and may be updated with new data from homologous and analogous traits, and molecular evidence, such as DNA or RNA sequences. The most recently evolved organism will be found at the tip of the branch that extends farthest to the right or top, depending on the tree's orientation.

Concerning the broader categories of life, all living organisms can be classified into three major clades: Archaea, Bacteria, and Eukaryota. Within Eukaryota, organisms are further categorized, such as the division between the animal phyla based on characteristics like the presence of differentiated tissues and body symmetry.

Radioactivity is the emission of particles and radiation from unstable atomic nuclei. For example, Carbon-14 is a radioactive isotope with 6 protons and 8 neutrons, unlike the stable Carbon-12 and Carbon-13. Carbon-14 decays over time, emitting radiation.

Radioactivity is the spontaneous emission of particles and radiation from atomic nuclei. This process occurs because unstable nuclei seek to achieve stability, emitting energy in the form of radiation.

To give an example, Carbon-14 (C-14) is a well-known radioactive isotope, which is commonly used in radiocarbon dating. Carbon-14 has 6 protons and 8 neutrons, whereas its stable isotope, Carbon-12 (C-12), has 6 protons and 6 neutrons.

Among these isotopes, Carbon-14 is a radioisotope due to its unstable nuclear configuration, which leads it to emit radiation as it decays over time.
