Which sentence best describes these two cell models? Apex (Sentences located in image)

yes because when things are flying, they have to be propelled. Thats how gravitty works lol.

If ur talking about stuff in space, then yes to that too. They moon revolves because of gravity and inertia

Yes, Earth's gravitational force field acts on objects that aren't touching Earth's surface. The gravitational force between two objects, like Earth and any other object, depends on their masses and the distance between them.

According to Newton's law of gravitation, the gravitational force between two objects is proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

The Earth's gravitational force is due to the planet's mass and size. All objects near the planet, including those above its surface, experience a gravitational pull because of the Earth's gravitational force.

Gravitational force is the force of attraction which is present between any two bodies and it is responsible for holding the objects in place.

Explanation:

1. An infinitely dense atom of matter explodes, releasing all matter in the known universe.

2. This matter clumps together forming rocks and dust; that which doesnt compact remains as gas.

3. The rocks and dust are pulled in to each other by their own gravity. These clumps get bigger and bigger, and form planets.

4. Gas and dust clouds, better known as nebulae, (sing. nebula) begin to react, clump together and generate heat. Stars are formed out of these nebulae (unsure of the process).

5. The stars, with their powerful gravitational pulls, drag in planets to form solar systems. This happens on a larger scale as well, as groups of millions of stars are formed into galaxies, huge swirling discs containing millions of stars each.

Answer:

The correct option is C

Explanation:

The central dogma involves conversion of DNA to protein. The DNA either undergoes transcription to form RNA or replication to form a new DNA. When transcription occurs, RNA is formed which can then be translated into protein. Consider the illustration below

DNA ⇒ RNA ⇒ Protein

There are three types of RNA

Of these three RNAs, the mRNA is the one translated into protein with the aid of the remaining two.

From the above, it can be deduced that DNA cannot be directly converted into protein.

The mode of transfer that does not occur in the process of genetic expression in cells is directly from DNA to protein. Information first passes from DNA to RNA, and then from RNA to protein.

In the process of genetic expression in cells, the mode of transfer that does not occur is DNA ---> Protein.

The usual sequence of information transfer is from DNA to RNA, and then from RNA to protein, a process known as the Central Dogma of Molecular Biology. The DNA is transcribed into messenger RNA (mRNA) in a process called transcription. The mRNA is then translated into protein in a process called translation.

Bacteria often contain plasmids, which are small, circular, double-stranded DNA molecules that can carry genes conferring beneficial traits such as antibiotic resistance.

Small circular molecules of DNA that are commonly found in bacteria are known as plasmids. These double-stranded DNA molecules are extrachromosomal, which means they exist independently of the bacterial chromosomal DNA. In the prokaryotic cells of bacteria, plasmids are located in the cytoplasm since bacteria lack a nucleus where eukaryotic DNA is typically found. The central region where the bacterial DNA resides is referred to as the nucleoid. Plasmids play a crucial role in the survival and adaptation of bacteria as they can carry genes that provide advantageous traits, such as antibiotic resistance. These plasmids can also be transferred between bacteria, a process which can lead to the spread of traits such as antibiotic resistance.

The bacterial DNA is organized within the nucleoid and a bacterium may have multiple plasmids. Each plasmid is a small, circular, supercoiled DNA molecule that often carries genes beneficial for bacterial survival under certain conditions, such as antibiotic or toxin-heavy environments. This demonstrates the importance of plasmids in the genetic adaptability of bacteria.

Answer: can be almost any size

Explanation: Plants are extraordinary organisms that come in a variety of shapes and sizes. The smallest is the watermeal (Wolffia globosa). With sizes of approximately 2 millimeters (0.079 in), it is also the smallest flowering plant in the world. One of the largest are the sequoia with heights of 70-85 meters and ages of over 3000 years old.

Plants are usually divided into two groups depending if they produce seeds or not. Thus, the three group title is unsuitable. As shown above, plants can reach extremely large sizes so the second title is unsuitable too.

All multicellular organisms contain specialized tissues, not only plants. Plants use active transport too and do not rely solely on diffusion. The last tile is also unsuitable as some plants do have true stems and leaves.

The best title for Paulo's presentation would be "How Plants Differ". This is because it is the most general title that encompasses all of the information in his notes. The other options are either too specific or not specific enough.

How Plants Differ is a good title because it covers all of the following points:

Plants can be divided into three groups: non-vascular, vascular, and seed-bearing.

Plants can be small or large, depending on the species.

Plants have specialized tissues, but they also use other mechanisms, such as active transport.

Some plants have true stems and leaves, while others do not.

The other options are not as good because they do not cover all of these points. For example, "Can Be Almost Any Size" is too specific because it only covers one of the points (that plants can be small or large). "How Plants Work" is not specific enough because it could cover a wide range of topics, not just the characteristics of plants.

Therefore, the best title for Paulo's presentation is "How Plants Differ".

It causes muscular irritability which can lead to cramps and twitching of facial muscles.

Final answer:

A drastic decrease in calcium production can lead to hypocalcemia, impacting muscle contractions and causing symptoms such as cramps, spasms, or tetany. Neurons can also be affected, leading to increased excitability and convulsions. Hypoparathyroidism, a common cause of low blood calcium, can severely disrupt neuromuscular function.

Explanation:

When there is a drastic decrease in calcium production in the body, it leads to a condition called hypocalcemia. This condition can negatively impact various systems within the body, including the muscular system. Without sufficient calcium, muscle contractions become impaired, which might lead to muscle cramps, spasms, or even prolonged contractions known as tetany. For neurons, low blood calcium can increase membrane permeability to sodium, which can result in muscle twitching and severe cases may lead to convulsions or paralysis, including respiratory muscles, and can prove to be fatal.

In the case of hypoparathyroidism, which is an underproduction of parathyroid hormone (PTH), there can be extremely low levels of blood calcium. As PTH helps regulate calcium levels in the blood, its deficiency can cause acute symptoms in muscle contractions and overall neuromuscular function. Muscle function impairment and tetany are common outcomes of severe hypocalcemia due to hypoparathyroidism.

C. Only tech A is correct

Explanation:

Oil control rings are designed differently than compression rings. A typical oil control ring consists of three separate pieces: two very thin metal rings called scrapers, and a spacer ring called an expander placed in the groove between them.

Final answer:

Technician A is correct in saying the oil control ring scrapes oil off the cylinder wall with each downward piston stroke. Technician B is incorrect; oil control rings can be a multi-piece component, not necessarily two pieces. The right answer is C, Technician A only.

Explanation:

The question asks who is correct regarding the function and structure of an oil control ring in an engine. Technician A states that the oil control ring scrapes oil off the cylinder wall with each downward piston stroke, which is accurate. Its main function is to clear excess oil from the cylinder walls and return it to the sump. Technician B is not correct in stating that a typical oil control ring consists of two separate pieces. In reality, the oil control ring can be even more complex, often consisting of two thin rails with a spacer expander, making it more accurately a multi-piece component. Therefore, the correct answer to this question would be C, Technician A only.

amino acid and RNA (or anticodon)

tRNA is used in the process of translation, which is when cells create a protein (polypeptide) from a strand of mRNA just came from the nucleus and is floating in the cytoplasm. This process occurs with the help of ribosomes!

A ribosome binds to an mRNA molecule, and tRNA's come swooping in one at a time to add amino acids to a growing polypeptide chain (protein).

On one end of the tRNA is a set of 3 RNA bases (called an anticodon), that binds perfectly to the opposing next 3 bases on the mRNA strand (called a codon) as it works it way through the ribosome. On the other side of the tRNA is the amino acid that the codon on the mRNA codes for, thus allowing the specific protein to grow 1 amino acid at a time.

Ecosystems can lose equilibrium due to catastrophic natural events, human-induced disruptions, and the loss of keystone species. These events can overwhelm the ecosystem's resistance and resilience, leading to irreversible changes or total collapse.

An ecosystem can lose its equilibrium due to several factors, both natural and human-induced. Natural events such as bushfires, droughts, floods, and volcanic eruptions can cause temporary or long-term disruptions in an ecosystem, impacting its health and leading to possible ecosystem collapse or the need for ecological succession. Human impacts, including the introduction of toxic substances like DDT or excessive fertilizers, can lead to the depletion of key species and alter nutrient cycles and energy flows, which are central to maintaining ecosystem equilibrium. Additionally, the loss of keystone species can set off an extinction cascade, fundamentally changing the ecosystem's composition and function.

It's essential to understand the concepts of resistance and resilience in ecosystems, which describe an ecosystem's ability to withstand disturbances and bounce back to a state of equilibrium, respectively. When human actions such as pollution, overfishing, or habitat destruction overwhelm an ecosystem's resilience, it can cripple the ecosystem's ability to return to its original state, potentially leading to irreversible changes or complete destruction.

The answer is; Plants both produce and use oxygen for photosynthesis and cellular respiration, respectively.

Plants use the energy from the sun to split water molecules to H+ and O2-. The H+ is used to reduce carbon dioxide into glucose molecules. The oxygen is a byproduct that is evolved. However, the cellular respiration of plant cells is similar to that of other organisms on earth. They utilize oxygen to ‘burn’ glucose for energy.

Final answer:

Plants produce oxygen as a byproduct of photosynthesis and also consume it during cellular respiration to produce ATP.

Explanation:

Among the given options, the true statement about oxygen in plants is that plants both produce and use oxygen for photosynthesis and cellular respiration, respectively. During photosynthesis, plants utilize carbon dioxide and water, using sunlight as an energy source, to produce glucose and release oxygen as a byproduct. However, the same plants also take in oxygen for the process of cellular respiration, which occurs in all parts of the plant, not just the green parts containing chlorophyll. Oxygen is necessary for this process as it helps to break down glucose, releasing energy in the form of ATP which the plant uses for its metabolic activities.
