Answer:

Newton’s first law (i.e about inertia) is best shown in this example.

Explanation:

Answer:

The correct option is A) The cell carries on metabolism.

Explanation:

During the interphase, the cell tends to carry out its normal cell activities and it prepares itself for the cell division process during the interphase. It synthesizes proteins etc which will be required for cell division during this phase. The cell becomes enlarged during this phase. A cell tends to spend most of its time in the interphase. Hence, option A is correct.

Other options, like option C, cannot be considered to be true because the process of cell splitting does not occur during the interphase, It happens during the process of cytokinesis.

Answer:

a rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants, fungi, and bacteria. In the algae and higher plants it consists mainly of cellulose.

Explanation:

A cell wall is an external, rigid structure found in plant, fungal, and some protist cells. Composed of varying molecules according to the type of cell, it protects the cell and maintains its shape.

The cell wall is a rigid structure that exists external to the plasma membrane in certain cells, particularly in plant cells, fungal cells, and some protist cells. It is primarily composed of various molecules including cellulose in plants and chitin in fungi. The cell wall serves to both protect the cell from environmental stresses like desiccation, changes in osmotic pressure, and traumatic injury and provides structural support, maintaining the shape of the cell. The composition of the cell wall can vary depending on the type of cell in question. For instance, in the case of plant cells, the cell wall is mainly composed of cellulose which is a polysaccharide comprised of glucose units. An example of how this works in everyday life would be when you bite into a raw vegetable like celery, the crunch comes from when the rigid cell walls of the celery's cells get torn by your teeth.

Answer:

Advances in the study of phylogeny led to a classification system based on evolutionary relationships. This new system is based on  the concept of a clade which contains a single common ancestor that all species within that clade descended from.

Explanation:

After Darwin's evolutionary studies, the scientists looked for a way to classify organisms on the basis of phylogeny. A phylogeny depicts the relationship between organisms based on the common ancestors that they might have. A phylogeny can be shown in a diagram like a cladogram. This diagram shows branches known as clade for each particular organism that might have evolved from a particular common ancestor.

Answer and Explanation:

Quarantine refers to a process in which people are isolated due to the possibility of spreading a disease. This is done to protect both the people who are in quarantine and the people that don't have the symptoms of a given disease. Mandatory quarantine refers to the legal process of people being unable to leave quarantine no matter the circumstance.

Although mandatory quarantines has many benefits as it prevents the public from being exposed to pathogens, it can have negative consequences. For example, there have been many cases in which children are left alone and isolated from parents due to the possibility of having a disease. Some professionals suggest children or parents to be able to be in quarantine at home. However, it is not as safe as other methods and mandatory quarantine is a legal procedure.

formula used: volume=density/volume

Explanation:

data:

volume=?

density(given)=917kg/m^3

mass(given)=0.0427kg

solution:

917/0.0427 =21475cm^3

The volume of the sample of vegetable oil is 4.66 x 10^-5 cubic meters.

First, we should recall the formula for density, which is:

Density = Mass/Volume

Using this formula, we can rearrange it to solve for volume:

Volume = Mass/Density

Plug in the given values:

Volume = 0.0427 kg / 917 kg/m3

Simplifying the expression, we get:

Volume = 4.66 x 10-5 m3

Therefore, the volume of the sample is 4.66 x 10-5 cubic meters.

Explanation:

Answer: Viruses infect cells by entering the cell almost disguising itself as a positive cell or object if you will. Once the virus is inside and the cell absorbs it thinking it is food or something else god knows what, the virus then replicates its DNA into the cell, replacing the RNA and infecting the cell, which then begins to multiply. Good Luck!

Explanation:

Final answer:

Viruses attach to specific receptors on host cells, inject their genetic material, replicate using the host's cellular machinery, and then release new viral particles, often destroying the host cell in the process.

Explanation:

Viruses are obligate, intracellular parasites that require a living host cell to replicate. They initiate infection by recognizing and attaching to cell-surface receptors on a permissive host cell, a process dictated by a molecular match between the virus and the viral receptor. After attachment, the virus enters the host cell, uncoats, and releases its genetic material, hijacking the cell's machinery to copy its genome and produce viral proteins. The new virus particles are then assembled and released, often killing the host cell through lysis or apoptosis. This infection process can cause cell damage and elicit an immune response from the host organism.

Host cell specificity is a hallmark of viral infections. For example, the influenza virus infects cells of the respiratory system due to the presence of specific receptors that the virus can bind to. Viral infection and replication depend on the cell's ability to produce necessary substances for the virus, and immune responses also play a role in determining which cells a virus may target.

Final answer:

The destruction of trees by elephants in southern Africa is a complex issue influenced by elephant overpopulation, their role as ecosystem engineers, and the competition for resources. Behavioural ecology studies, including the creation of an acceptability index, offer insights into the dietary habits of elephants and the reasons behind tree damage. Protection strategies against poaching and habitat loss are also integral to understanding the broader context of elephant conservation efforts.

Explanation:

The problem of elephants destroying trees in southern Africa is often attributed to a combination of factors, primarily overpopulation and competition for resources. Due to conservation efforts, elephant populations have rebounded in many areas, but this success can lead to increased pressure on the environment. As dominant ecosystem engineers, elephants can significantly affect biodiversity and ecosystem processes based on their population density. Moreover, the impact on tree species within protected areas can be assessed by recording the types of damage inflicted on trees, such as broken branches and bark stripping. Understanding why elephants damage trees involves examining their diet and movement patterns through behavioural ecology. By calculating an acceptability index of each tree species (eaten versus available), researchers gain insight into the foraging preferences of elephants, which helps to clarify whether the destruction is due to the preference for certain tree species or if the trees are damaged as byproduct of elephants' movements.

Poaching, habitat loss, and human-elephant conflict also influence the dynamics between elephants, their environment, and local communities. Strategies to protect elephants from poachers, such as establishing national parks and creating ecotourism opportunities, provide varying levels of effectiveness and incentives for conservation efforts, impacting both elephant populations and their habitats.

Removing trees  in large amount can cause climate change, extinction of species and hence the food cycle as well as the ecosystems

Explanation:

Deforestation is the major cause of climate change. The atmosphere gets filled with greenhouse gases which would lead to an increase in temperature. We need oxygen to live which is coming from the plants, removing would affect these cycles. several species of animals have been already extinct and continuation of this activity would end up the removal of many organisms from the food cycle and finally, we will be removed.

During the horizontal line, the body was not increasing height, was vertically at rest.

Explanation:

The graph given here is a graph between the elevation and time. This graph plots movement of a body on its y axis vs time where it's seen that the body is increasing steadily in height for the first 2 minutes from when it suddenly takes a horizontal line. It means that after 2 mins, the body comes to a rest at the vertical movement. For the next 3 mins, the body remained as the same state of movement, at vertical rest. After that, the body started coming down i.e decreasing its height for the next 2 mins. Then it again started increasing its height from reference ground, untill 9 mins after which it again came at vertical rest.

Helium is an element with an atomic number of 2 which means that it has 2 protons in its core. So if any atom has 2 protons in its core, they it's helium no matter what.

On the periodic table of elements which I have attached in the image provided, the whole numbers in the tile tell you the number of protons. So helium  is a noble gas which is found in the top right of the periodic table and I have drawn an arrow the atomic number which is the number of protons.

Helium has two protons in its nucleus, which define it as the element helium. The most common isotope of helium, ⁴He, has two neutrons in addition to the two protons.

The number of protons in an atom defines the identity of an element, and for helium (He), this number is two. Therefore, helium has two protons in its nucleus. Helium is also known for its isotopes.

For instance, the most common helium isotope has two neutrons along with the two protons which is represented as ⁴He, due to its mass number being 4 atomic mass units (2 amu from protons and 2 amu from neutrons).

However, there are also other helium isotopes, such as ³He, which have a different number of neutrons, but the number of protons remains the same at two. This defines the element as helium regardless of its isotope.

Large molecules such as hormones materials are expelled from cells during exocytosis

Explanation:

The materials inside the cells are transferred to the outside of the cell and this manner is termed as  Exocytosis. This method is termed as a kind of active transport since it needs energy for this transformation process. One of the major purposes of this process is to discharge trash matters like hormones and proteins.

For a cell to cell transmission and chemical signal messaging these methods are essential. Proteins that are newly generated are transferred to the peak of the plasma membrane by exocytosis. There are three general pathways of exocytosis.

Final answer:

Materials expelled from cells during exocytosis largely consist of large molecules such as hormones, digestive enzymes, and neurotransmitters, which are integral to many bodily functions.

Explanation:

During the process of exocytosis, cells expel various materials into the extracellular space. The types of materials that are commonly released during exocytosis include large molecules such as hormones, digestive enzymes, and components of the extracellular matrix, as well as neurotransmitters. These materials are packaged into vesicles within the cell. When the vesicle membrane fuses with the plasma membrane, it releases its contents outside the cell. The identified options related to large molecules such as hormones specifically refer to the frequent export of proteins and glycoproteins that play critical roles in the body, from acting as biological messengers to facilitating digestion and immune responses.

Answer:

cochlea.

Explanation:

When a sound wave hits the eardrum, the eardrum moves tiny bones — the malleus, incus, and stapes — which subsequently move.

This movement is picked up by the mechanoreceptors in the inner ear, which exist on hair cells containing cilia between the end of the semicircular canals and the vestibule.

When the cilia move, the cells create an impulse that is sent through the cochlea to the eighth cranial nerve, which carries the impulse to the brain.

The brain then interprets the information as a specific sound.
