A. The core accretion model states that planets form when clumps of gas and dust collapse, while the gravitational instability model states that small bodies grow bigger and attract layers of gas to form planets.

There are two main models of planet formation: the core accretion model and the gravitational instability model.

The core accretion model states that planets form when small particles, such as dust and gas, clump together and gradually grow into larger bodies. These bodies continue to attract more material, eventually forming a planet. This model is supported by the observed existence of small, solid bodies, known as planetesimals, in the early solar system.

The gravitational instability model, on the other hand, proposes that planets form when small bodies within a protoplanetary disk (a disk of gas and dust surrounding a young star) grow larger and become gravitationally unstable. This causes them to collapse and attract layers of gas, eventually forming a planet. This model is supported by the observation of large, gaseous planets, such as Jupiter, in the solar system.

B. A recognition molecule on the surface of the cells.

An antigen is a substance that is capable of triggering an immune response in the body. It is typically a foreign substance, such as a pathogen (e.g. a virus or bacterium), a toxin, or a non-infectious particle (e.g. pollen or dust), that is recognized by the immune system as being foreign and potentially harmful.

When an antigen enters the body, it is recognized by immune cells called B cells and T cells, which produce proteins called antibodies to help neutralize and remove the antigen. The antigen-antibody interaction is a key part of the body's immune response and helps to protect us against infectious diseases.

Antigens can also be present on the surface of our own cells, such as cancer cells or transplanted organs, and can trigger an immune response if they are recognized as foreign by the immune system.

Overall, antigens are important components of the body's immune system and play a critical role in protecting us against infectious diseases and other threats.

Option d.) Bacteria can take up free fragments of DNA from the environment. This is the correct answer.

Competent cells are bacterial cells that take up extrachromosomal DNA or plasmids from the environment. Competent cell generation can be done in two ways- natural competence and artificial competence. Natural competence is the genetic ability of bacteria to take up environmental DNA under natural or in vitro conditions. Bacteria can also be artificially rendered capable of being temporarily permeabilized by DNA through chemical treatment and heat shock. Natural Competence dates back to 1928, when Frederick Griffith discovered that thermal cells prepared from pathogenic bacteria could transform non-pathogenic cells into pathogenic cells.

However, natural capacity and transformation are valid for linear molecules such as chromosomal DNA, but not for circular plasmid molecules.

The deer population size when scientists catch, mark and release 150 deer. later, they return and catch 120 deer of which 40 were those earlier marked is 450.

To calculate the population size using the mark and recapture method. In this method, scientists capture a sample of individuals, mark them, and then release them back into the population. They then capture a second sample and use the proportion of marked individuals in the second sample to estimate the size of the entire population.

The formula for the mark and recapture method is:

N = (M × n) / R

where N = the size of the population, M = the number of individuals in the first sample (marked), n = the number of individuals in the second sample, and R = the number of marked individuals in the second sample.

Plugging in the values given in the question:

N = (150 × 120) / 40N

= 450

Genetic drift is a phenomenon that occurs in small populations where random events can have a significant impact on the genetic makeup of the population which reduces the overall genetic diversity of the population.

It can either reduce or increase genetic variation in a population, depending on the direction of the random events. The correct answer to the multiple-choice question is that genetic drift reduces genetic variation in a population. This is because, in small populations, random events such as genetic mutations or environmental factors can have a greater impact on the gene pool. Over time, this can lead to the loss of certain genetic traits, which reduces the overall genetic diversity of the population. Therefore, genetic drift is an important factor to consider when studying the genetic makeup of populations, especially those that are small and isolated. Answering in more than 100 words, genetic drift is an important concept in population genetics, and its effects on genetic variation can have significant implications for the long-term survival of a population.

Enzymes catalyze chemical reactions and increase reaction rates by lowering the activation energy of the transition state. One way that an enzyme can lower the transition state is by bringing the reactants together at the right orientation and energy. This is called proximity (option A).

Proximity refers to the ability of an enzyme to bring the reactants closer together, thereby increasing the likelihood of a successful reaction. By bringing the reactants into close proximity, the enzyme can effectively lower the activation energy of the transition state, leading to an increase in the rate of the chemical reaction.
In contrast, options B, C, D, and E refer to different mechanisms by which enzymes can catalyze chemical reactions. Group transfer (option B) involves the transfer of a functional group from one molecule to another. Distortion (option C) involves the distortion of the substrate molecule to make it more reactive. General acid-base catalysis (option D) involves the transfer of protons between the enzyme and the substrate. Intermolecular force stabilization of the transition state (option E) involves the stabilization of the transition state through intermolecular forces such as hydrogen bonding.
Therefore, the correct answer to this question is option A, proximity.

The first life on Earth was prokaryotic. There're different theories about the origin of these kinds of cells, among them we can find how it's hypothesized that these basic forms of life came up from other planets in meteorites, what it's known as the panspermia theory of life. On the other, there's said that the primitive conditions after the formation of our planet gave place to cyclic inorganic molecules that replicate themselves in a physicochemical equilibrium, as happens today with the nutrients cycle, for example, and in a primordial soup, these replicated molecules began to conform more complex structures like nucleic acids that lead to the formation of live organisms. Maybe they resulted after those basic molecules were progressively being part of other molecules, and involved other molecules in their basal structures, such as states the endosymbiotic theory. Or maybe the origin of those basic forms of life is the result of these and other theories in conjunction .

The movement that you are referring to is known as abduction. It is a movement that occurs in coronal plane, where a body part moves away from the midline of the body.

This can occur in any joint, including the shoulder, hip, and knee. Abduction is the opposite of adduction, which is a movement that brings a body part closer to the midline of the body. For example, lifting your arm out to the side is abduction, while bringing your arm back down to your side is adduction.
Abduction is an important movement in many activities, such as sports and fitness. For example, in basketball, players use abduction to move their arms out to the side to block a shot or grab a rebound. In weightlifting, exercises such as lateral raises and leg lifts are designed to target the muscles that perform abduction.
Overall, abduction is an important movement that allows us to move our limbs away from our body and perform a wide range of activities.

Answer:

The major components of bone tissue at the molecular scale are minerals, water, collagen, and other proteins. At the next level of organization, small crystals of hydroxyapatite made of calcium and phosphate are embedded within collagen fibers to produce a composite (blended) material with high compressive and tensile strength.

The skeletal system protects and supports vital organs, allows our body to move, stores important minerals, and produces blood cells. There are several chemical elements and molecules required to maintain the many functions of the skeletal system. The chemical properties of these components support bone structure and function. On a chemical level, bone is divided into inorganic and organic (carbon-containing) components.

The primary inorganic components of bone are:

calcium, which is required for many functions throughout the body;

phosphorus (in the form of phosphate ions), which is a component of buffer systems and energy-rich molecules; and

water, which contributes to the compressive resistance of bone and contributes to the fluid matrix of bone.

The primary organic components of bone are:

collagen, the major structural protein (type I in bone and type II in cartilage); and

proteoglycans, which are negatively charged glycosylated proteins (glycosylated means having carbohydrate sugar groups modifying the protein).

Bone is approximately 60 to 70 percent inorganic mineral and 10 percent water by weight. The remaining 20 to 30 percent of bone is organic matrix (osteoid), such as collagen and proteoglycans. Your body contains 1 to 2 kilograms of calcium and nearly 600 grams of phosphorous. Nearly 99 percent of the calcium and 86 percent of the phosphorous is stored in your bones.

Inorganic Components of Bone

Calcium ions (Ca2+) are stored in bone tissue, but can be released into the bloodstream when blood levels fall below optimal. Blood calcium is important for muscle contractions, nerve impulses, and blood clotting.

In bone, phosphorous (P) is found in the form of phosphate ions (H2PO4–). Outside of bone, phosphorous plays roles in energy storage (such as in ATP), and is required for the formation of DNA and RNA. Therefore, it is required for cellular growth, maintenance, and tissue repair.

When combined with hydrogen, phosphorous forms dihydrogen phosphate ions (H2PO4–). Dihydrogen phosphate acts as a buffer to maintain a constant pH balance by acting as either a hydrogen ion donor (acid) or a hydrogen ion acceptor (base). In all cells, a constant pH must be maintained to carry out cell functions.
