Final answer:

Dry ice consists of CO₂ molecules held in a regular, extended crystalline structure by weak intermolecular forces, similar to water ice's hydrogen-bonded crystal lattice, though with significantly weaker bonding.

Explanation:

The structure of dry ice, or solid carbon dioxide (CO₂), is formed by individual CO₂ molecules where each carbon atom is doubly bonded to two oxygen atoms. In its solid form, these molecules are held together in a crystal lattice by very weak intermolecular forces, which leads to dry ice's high volatility. This structure is vastly different from that of silicon dioxide, which forms a continuous covalent network. Still, the essence of a crystalline structure in dry ice is that it has an orderly and repeating pattern, akin to water forming an ice crystal structure with an open, cagelike arrangement due to hydrogen bonding. In other words, dry ice's crystalline arrangement is such that molecules stack in a regular pattern, similar to other crystal lattices, even though the bonding forces in dry ice are much weaker, leading to its sublimation at room temperature.

Answer:

Troposphere is the lowest layer of Earth’s atmosphere that has undergone a large increase in temperature due to the  presence of greenhouse gases.

Explanation:

Troposphere (0 to 12 km) where we live is the lowest layer of earth's atmosphere, which is closest to the earth's surface contains half of the atmosphere. Here most clouds are found and almost all weather occurs. Atmosphere contains approximately 78% of nitrogen , 21% of oxygen and 0.9% of argon. Gases like carbon dioxide, nitrous oxides, methane, ozone and the water vapor constitutes the rest of the atmosphere. Many small particles called aerosols are also there which include dust, spores, pollen, volcanic ash, smoke etc.The greenhouse effect is a natural phenomenon that keeps the temperature on the earth suitable for supporting life. The greenhouse gases includes both natural and man-made gases like carbon dioxide , methane, nitrous oxide, chlorofluorocarbons, hydrochlorofluorocarbons, ozone, water vapour. They absorb radiation in the atmosphere and create the green house effect. The thermal infrared radiation emitted by the Earth’s surface and the atmosphere is absorbed by greenhouse gases. They trap heat within the surface-troposphere system preventing it from escaping back into space. This is called the greenhouse effect, which increases the temperature of the lower atmosphere.The increase in the atmospheric concentrations of greenhouse gases due to human activity has caused an increase in the natural greenhouse effect. As a result, the atmosphere is trapping too much heat which increases the temperature of the Earth.

The troposphere has experienced a significant temperature increase due to greenhouse gases trapping heat, a process known as the greenhouse effect.

The atmospheric layer that has undergone a large increase in temperature due to the presence of greenhouse gases is known as the troposphere. The troposphere is the lowest level of Earth's atmosphere, extending up to 12-15 km from the surface. Greenhouse gases such as carbon dioxide and water vapor play a crucial role in trapping heat within this layer through the greenhouse effect, maintaining Earth's surface temperature at levels suitable for life. This warming of the troposphere has become more pronounced in recent times, resulting in what is referred to as the enhanced greenhouse effect, contributing to global warming and climate change.

Answer:

C. Phosphorus (P)

Explanation:

Given;

Electron configuration [tex]1s^22s^22p^63s^23p^3[/tex]

Firstly we have to find out the number of shell of given element. For this we have to add number of electron of each shell.

Here counting goes to 3 that means element have three shells. Now we find out number of electrons in each shell.

First shell of an element is K and it has only one sub shell that is 1s. In this element 1s contains only 2 electrons.

For 2nd shell that is L has two sub shell 2s and 2p, for this element 2s contains 2 electrons and 2p contains 6 electrons. That means total number of electrons for L shell is 8.

Now for 3rd  shell that is M has two sub shell 3s and 3p, for this element 3s contains 2 electrons and 3p contains 3 electrons. That means total number of electrons for M shell is 5.

Now total number of electrons for the element is the sum of number of electrons in each shell.

Total number of electrons = 2+8+5=15

And we know the number of electrons of any neutral element is equal to the number of protons and number of protons gives us atomic number of the element.

So the atomic number of given element is 15 that is of Phosphorus.

Answer:

Phagocytosis refers to the engulfing of larger, solid particles. Often, the engulfed particle is another cell, like when a white blood cell, which is a part of the immune system, engulfs a bacterium to destroy it.

Final answer:

Phagocytosis is the process by which a cell engulfs and destroys large particles, such as microorganisms, through a type of white blood cell known as a neutrophil.

Explanation:

The act of white blood cells engulfing a bacterium is known as phagocytosis. Phagocytosis is a crucial defense mechanism employed by certain white blood cells, particularly neutrophils and macrophages, to eliminate foreign particles, such as bacteria and other microorganisms.

During phagocytosis, the white blood cell surrounds the bacterium with its cell membrane, forming a vesicle called a phagosome. Subsequently, lysosomes, which contain digestive enzymes, fuse with the phagosome to create a phagolysosome. The enzymes within the phagolysosome break down the engulfed bacterium, rendering it harmless.

Phagocytosis is a fundamental aspect of the innate immune response, serving as a primary line of defense against infections. It plays a crucial role in maintaining the body's overall health and protecting against a variety of pathogens.

Answer:

C) They invade the body and can cause a humoral immune response.

This best explains the impact that pathogens in the environment might have on one's body.

Explanation:

Pathogens are the microorganisms that are found in the environment and have the tendency to cause diseases. The human body has various lines of defenses against the incoming pathogens, the Nonspecific responses keep the pathogens outside the body and these responses are common for all pathogens. If a pathogen manages to enter the body, then a series of specific responses are triggered which are focused on the type of pathogen.

The humoral response is a category of specific immunity and involves the substances found in body fluids. It particularly targets the newly invading pathogens. Hence, option C correctly describes the impact of pathogens on the body.

 Both the sunflower and gingko have cones.

The life cycle of sunflowers involves double fertilization; the life cycle of ginkgoes involves single fertilization.

Explanation:

An angiosperm refers to plants which are flower bearing and usually bisexual. The angiosperms are a large group and include grasses, herbs, shrubs and trees. A gymnosperm refers to plants whose seeds are borne on the female cones and seeds are not enclosed in a fruit wall. The gymnosperms comprise of coniferales, cycadales and ginkgoales. Both the sunflower (angiosperm) and ginkgo (gymnosperm) are seed-producing plants. However, the seeds of a sunflower are enclosed by a flower or a fruit wall, while in case of Ginkgoales they are not. Also, sunflowers include double fertilization, while the Ginkgoales involve only a single fertilization.

Answer:d

Answer:

b

Explanation:

A patient with diseased tissues that remove wastes and toxic matter from the blood would require a kidney transplant. Matching a donor is essential to prevent immune rejection, and scientists are exploring growing organs from the patient's own cells to avoid this issue.

The group of tissues that removes wastes and toxic matter from the blood is primarily the kidneys. When these tissues are diseased, the patient would typically require a kidney transplant to replace the failing kidneys. For an individual requiring a transplant, finding a matching donor is crucial to prevent tissue rejection. This is due to the immune system potentially destroying the donor cells, recognizing them as foreign. Patients receiving bone marrow transplants, for instance, must have their own diseased marrow destroyed beforehand, and then donor stem cells are intravenously infused. However, in the case of a kidney transplant, the procedure involves connecting a donated kidney to the recipient's blood vessels and leaving the diseased kidneys in place if they're not causing complications.

Dialysis is an alternative treatment that filters blood using a machine, but it is not a cure for kidney failure. For patients with end-stage kidney disease, a kidney transplant is the ideal alternative to long-term dialysis. The main obstacle with transplantation is finding a donor that matches the patient's human leukocyte antigens (HLAs), which are critical for reducing the risk of rejection.

The oceans absorb more carbon dioxide than the atmosphere.

Explanation:

Oceans are absorbers of atmospheric carbon dioxide. Like in the terrestrial environment ocean animals take in oxygen and release carbon dioxide and ocean plants perform photosynthesis by absorbing carbon dioxide and releases oxygen.

Various human activities like burning of fossil fuels and several industrial activities cause the release of carbon dioxide in large amounts into the atmosphere which harms the earth and its inhabitants.

About one-fourth of the carbon dioxide produced in the atmosphere is absorbed by the oceans of the earth. Oceans are the carbon sink of earth. Absorption of carbon dioxide makes the ocean acidic which causes harm to several ocean beings.

Explanation:

i think not for sure tho

Breathing supplies oxygen necessary for cellular respiration, which produces energy for cellular processes. Oxygen is a key reactant that aids in the transformation of glucose into ATP while expelling carbon dioxide as a byproduct.

Breathing is essential for cellular respiration, a process where cells break down glucose (from our food) in the presence of oxygen to release energy, carbon dioxide, and water. This process can be represented by the chemical equation: C6H12O6 + 6O2
ightarrow 6CO2 + 6H2O + Energy. When we inhale, oxygen is absorbed into the bloodstream and delivered to our cells, where it serves as a crucial reactant in cellular respiration. Conversely, when we exhale, we expel carbon dioxide, a byproduct of this process. During cellular respiration, energy is transformed into ATP, the main energy currency of the cell, which then powers various cellular functions.

The process of photosynthesis in plants produces the glucose and oxygen needed for cellular respiration. Photosynthesis and cellular respiration form a cycle, highlighting the interconnectedness of life processes. Oxygen plays a critical role as the final electron acceptor, allowing for complete glucose breakdown and ATP production, and without it, much less ATP would be generated, impeding our body's ability to perform functions effectively.

Answer: Explain why two different enzymes are needed for the synthesis of glycogen from glucose phosphate. This is because enzymes are substrate specific, in that each enzyme only catalyzes one substrate. This is because enzyme activity increases with concentration, or availability of the substrates.

Explanation:

Answer:

Two different enzymes are needed for the synthesis of glycogen from glucose phosphate due to enzymes being only able to catalyze only one type of substrate.This simply every enzyme has only one type of substrate which it acts on.

Enzymes help to regulate the complex chemical reactions that occurs in organisms by speeding it up.This is essential to prevent starvation of various nutrients or compounds needed by the body.

In this scenario, there are two enzymes which aids the synthesis of glycogen from glucose phosphate.

Explanation:

-Carbohydrates act as signals or markers to help cells recognize one another.

Carbohydrates are organic macromolecules with a range of functions within organisms. They may act as energy storage, structural support, and signal molecules. Together with transmembrane proteins embedded within the membrane from the extracellular fluid to the cytoplasm, they form glycoproteins (proteins attached to carbohydrates) which function as cell surface markers .

Further Explanation:

Carbon, is the backbone of all biological life on Earth. It contains 6 electrons, with 4 on its valence shell, and thus, readily forms covalent bonds with other elements. Covalent bonding involves the sharing of electrons; in nature, this occurs with hydrogen,oxygen, nitrogen, and phosphorus as highly flexible single bonds capable of rotation; rigid, non-rotating  double; and very strong triple bonds. Carbon compounds form rings, and long branched chains- thus, carbon can form macromolecules in nature.

In nature, organic compounds may be large chains of monomers form biological macromolecules which carry out many essential functions in the body. These can include nucleic acids, carbohydrates, proteins and lipids. These are organic molecules, meaning they're ringed or long-chain Carbons bonded to the elements oxygen (O), hydrogen (H), nitrogen (N) and phosphorus (P); they are found in essential organic biomolecules include, proteins, nucleic acids, lipids and carbohydrates.

Carbohydrates function to supply energy and support molecules they consist of mainly sugars or starches in long chains and rings to form monosaccharide monomers. They include monosaccharides, disaccharides and polysaccharides which describes the type of bonding and the degree of complexity of the polymers. Basic makeup: C, H, O -with many polar OH groups
