When the cell engulfs large fragments of matter, it is called _____. Select all that apply. endocytosis exocytosis pinocytosis phagocytosis
Final answer:
The correct processes when a cell engulfs large fragments of matter are called endocytosis and phagocytosis. Phagocytosis is the cellular process of engulfing solid particles, while pinocytosis takes in liquid substances. Exocytosis is the opposite process and is not a correct answer to the question.
Explanation:
When a cell engulfs large fragments of matter, the processes involved are called phagocytosis and endocytosis. Phagocytosis, a form of endocytosis, is like the cell eating. It is used by cells such as immune cells to engulf and digest large particles like invading pathogens or debris. This process involves the cell membrane surrounding the particle, and then pinching off to form a vesicle that's brought into the cell.
Another form of endocytosis is pinocytosis, also known as cell drinking, where the cell takes in fluid containing dissolved substances instead of large particles.
It's important to note that exocytosis is the opposite process, in which materials are expelled from the cell, and should not be confused with endocytosis. Therefore, the correct answers for the cell engulfs large fragments of matter are endocytosis and phagocytosis

What would cells want to keep some particles in homeostasis and others in equilibrium?
Final answer:
Cells maintain homeostasis to ensure optimal functioning and survival, and use processes like active transport and diffusion to either regulate specific particles strictly or allow them to reach equilibrium with the environment.
Explanation:
Cells strive to maintain homeostasis, which is the balance or equilibrium within the cell that allows it to function optimally. To achieve this, cells regulate their internal environment through homeostatic regulation, a process that involves making continuous adjustments to maintain a set point. Some particles must be kept in homeostasis to ensure a stable internal environment, while others are allowed to reach equilibrium with the environment to function properly. For example, certain ions are kept at specific concentrations within the cell to maintain electrical gradients critical for processes like muscle contraction and nerve impulse transmission. On the other hand, cells allow some substances, like oxygen and carbon dioxide, to reach equilibrium through diffusion to facilitate respiration and energy production.
Active transport and diffusion play significant roles in homeostatic regulation, ensuring that particular substances are maintained at correct levels inside and outside the cell. The cell membrane's selective permeability plays a key role here, allowing for the discrimination of which particles to keep in equilibrium and which to regulate strictly for homeostasis. For instance, while glucose levels are regulated tightly to provide energy and prevent detrimental effects associated with high blood sugar, oxygen concentration is allowed to equilibrate to meet the metabolic demands of the cell.
Growth, reproduction, and dynamic homeostasis are complex activities requiring cells to create and maintain internal environments distinct from their external environments. This dynamic balance facilitates life processes and determines the cell's ability to respond adaptively to changes, ensuring the organism's survival.

one
Why does this trait tend to be passed on from generation to generation?
Polydactyly, or the presence of more than five fingers or toes, can be caused by a genetic mutation, which is why it can be passed down from generation to generation as it is hereditary.
What is polydactyly?Polydactyly is a condition in which an individual has more than five fingers or toes on their hands or feet. This condition can be caused by a genetic mutation, which is a change in the DNA sequence of a gene. In the case of polydactyly, the mutation may result in the formation of extra digits during development. When a genetic mutation occurs, it can be passed on to an individual's offspring through their genes. This means that if an individual with polydactyly has children, there is a chance that their children will also have the condition.
Hence, polydactyly, or the presence of more than five fingers or toes, can be caused by a genetic mutation, which is why it can be passed down from generation to generation as it is hereditary.

Define the term cell differentiation and describe its importance to an organism
Cellular differentiation describes how different cells perform different processes and have unique functions. There are at least 250 cells in the human body and each one plays a different role, and all of them are crucial to the body's ability to maintain homeostasis. For example, liver cells produce proteins that are important in blood clotting. If these cells are damaged, blood will not clot properly. If blood does not clot, a body cannot maintain homeostasis and the person will fall ill.
TL;DR: every cell plays its part and keeps the organism alive.

When two hydrogen atoms are smashed together creating helium atoms and energy, what is occurring?
Answer:
NUCLEAR FUSION
Explanation:
A nuclear fusion reaction is so named because the nuclei (center) of atoms fuse (join) together in the process. In stars like our Sun, hydrogen atoms join together to create a helium atom. Nuclear fusion reactions need a lot of energy to get started. Once they begin, they produce even more energy
Nuclear fusion is the process where hydrogen atoms combine to form a helium nucleus, releasing energy. This energy is produced due to the mass discrepancy between the initial hydrogen atoms and the resulting helium, and it's the same reaction that powers the Sun.
When two hydrogen atoms are smashed together creating helium atoms and energy, a process called nuclear fusion is occurring. In the Sun's core, this process begins with two protons fusing to form a deuterium nucleus, an isotope of hydrogen with one proton and one neutron. Through a series of reactions, including the proton-proton chain, four hydrogen nuclei eventually combine to create a single helium nucleus and energy. The energy released is due to the mass difference between the reactants (hydrogen) and the products (helium), following Einstein's mass-energy equivalence principle, E=mc².
This fusion process releases energy because the mass of the helium nucleus is less than the total mass of the four hydrogen nuclei. The excess mass is converted into energy, which is emitted in the form of photons (light energy) and other particles. This process is the same that powers the Sun, providing light and warmth to our planet.

B. viruses are unable to infect humans
C. diseases caused by bacteria aren’t serious
D. antibiotics can always be used to treat bacterial infections
We don’t know of any archaea that are harmful. Option A
What is bacteria?Although they resemble bacteria, archaea are separate microorganisms. There is little evidence that archaea, unlike other pathogenic bacteria that cause disease, are detrimental to humans or other species. Although most archaea are recognized for their functions in harsh settings, they rarely cause illness.
Archaea are distinguished from disease-causing bacteria by their lack of known negative effects. This helps to explain the notion that, to date, no pathogenic or dangerous archaea have been found, which separates them from bacterial agents that cause disease.

A) it is single stranded
B) it has 4 nitrogenous bases
C) it has a ribose sugar
D) it has thymine instead of uracil
E) it helps make proteins
Answer:
it is D. it has thymine instead of uracil
Explanation:
The incorrect statement about RNA is that it has thymine instead of uracil. In RNA, uracil is the base that pairs with adenine, not thymine.
Explanation:The statement that is not true about RNA is D) it has thymine instead of uracil. The truth is that in RNA, thymine is replaced by uracil. This means that uracil pairs with adenine in RNA, not thymine. So while DNA uses adenine, guanine, cytosine, and thymine, RNA uses adenine, guanine, cytosine, and uracil. The other statements about RNA being single-stranded, having 4 nitrogenous bases, containing ribose sugar, and helping to make proteins, are all accurate.

the characteristics of certain cell divisions are described in the following table which type of cell division do the two characteristics represent???
characteristic 1 forms diploid cells
characteristic 2 creates sex cells or gametes
A those characteristics represent meiosis.
B both characteristics represent mitosis.
C characteristic 1 represents meiosis and characteristic 2 represents mitosis.
D characteristic 1 represents in mitosis and characteristic 2 represents meiosis.
Final answer:
Characteristic 1 corresponds to mitosis, which forms diploid cells, while characteristic 2 corresponds to meiosis, which creates gametes or sex cells.
Explanation:
The two characteristics presented in the question describe two different processes of cell division:
Characteristic 1 forms diploid cells.
Characteristic 2 creates sex cells or gametes.
In the context of cell division, mitosis is a process that results in two daughter cells that are genetically identical to each other and the original parent cell. These daughter cells are diploid, meaning they have the same number of chromosome sets as the parent cell, which for most animals and plants is a pair of each chromosome type. Meiosis, on the other hand, is a two-round division process that produces four daughter cells that are haploid and genetically diverse. These haploid cells are the gametes or sex cells, having half the number of chromosomes as compared to the parent cell.
Therefore, the correct answer to the question is that characteristic 1 represents mitosis, where diploid cells are formed, and characteristic 2 represents meiosis, which creates gametes or sex cells.

Which of the following makes fungal pathogens more difficult to treat with medication?
A. They are eukaryotic cells that have their own cell membranes.
B. They aren't living, so can't be treated with antibiotics.
C. They prevent the body from digesting medications.
D. They are often fast-acting infections that don't provide time for medication.
The answer would be A.
Fungi are harder to treat than bacteria bc they are eukaryotes and bacteria are prokaryotes. Bacteria have a cell wall made up of peptidoglycan and most antibiotics target that in order to destroy them and get rid of the infection.
Hope this helps:)
Answer:
The correct answer would be option A.
Explanation:
Fungal infections are commonly very tough to treat because, not like bacteria cells, fungi are eukaryotes and more close to the animals. Many fungal diseases are superficial; that is, they occur on the animal's skin.
Antibiotics only attack and kill prokaryotes, whereas medications that kill or harm fungi cells also harm the eukaryotic animal host because both have a similar type of cell membrane.
Thus, the correct answer is option A.
