Animal poisons work on the cell membrane by causing reaction with it which damages the structure of the cell membrane.

The structures of poisons are not similar to those chemicals that are essential to cells. Very few poisons are absorbed by active transport when a toxic level of the chemical is collected in the cells of the specific tissue or organ, which results in the disrupts of the cell from its normal structure or function. Symptoms of poisonous chemicals then develop, and, if the toxicity is severe , death may occur. Diffusion, facilitated diffusion, active transport are the types of chemical transport systems through cell membranes. Lipophilic is a nonpolar chemicals that dissolve in the lipid bilayer.

So we can conclude that animal poisons are neurotoxic that cause actions on the cell membrane.

elements are recombined in different ways is the Matter Cycle Model

This model explains that matter cycles through the environment in a continual cycle, with elements being reused and recombined in different ways. This cycle includes the processes of photosynthesis, respiration, decomposition, and remineralization.

The continual movement of matter from one location to another can have either good or harmful effects. Both naturally and as a result of human activity, matter cycles.

Small intestine

In humans, the ileum is where food is digested during the active transit process (small intestine). After some time has passed after food has been absorbed by the villi, the concentration of food molecules increases, at which point no more food can diffuse in.

High concentrations of substances the cell needs, like ions, glucose, and amino acids, are typically accumulated during active transport. Active transport examples include the uptake of glucose in human intestines and the uptake of mineral ions into plant root hair cells.

In DNA replication, two DNA double helices are synthesized from one DNA double helix molecule when it unwinds and complementary nucleotides are added to the exposed unpaired bases.

A double-stranded DNA molecule is duplicated to create two identical DNA molecules through the process of DNA replication. Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.

The fundamental mechanism of DNA replication is similar across all species, making it a crucial operation.

Prokaryotic cells' cytoplasm and eukaryotic cells' nuclei are where DNA replication takes place. The fundamental steps of DNA replication are the same wherever it takes place. DNA replication is made simple by the DNA structure. The double helix has two opposing (anti-parallel) directions running through it.

This transmission electron micrograph clearly shows the cell wall, nucleus, vacuoles, mitochondria, endoplasmic reticulum, Golgi apparatus, and ribosomes.

Once you can see the cells, carefully turn the coarse focus slider. Once the cells are in focus and are clearly visible, carefully turn the fine focus knob. To see the cells in greater detail, repeat steps 1 through 5 with the higher power magnification.

So, to study cells, scientists utilize microscopes. Compared to light, electron microscopes offer greater magnification, more resolution, and more detail.

Under a light microscope, the nucleus, cytoplasm, cell membrane, chloroplasts, and cell wall can all be seen as organelles. Although mitochondria can still be seen under a light microscope, extensive investigation is not possible.

Explanation:

Answer: The Correct answer is 3) Negatively charged electrons can move freely through a metal

Explanation:

The electric current can pass easily through a metal because the electrons or negatively charged ions are relatively free to move in metals. So, whenever current pass-through metals, electrons carry electricity and pass it through the metal. The movement of these electrons are the reason for conduction of current in metals.

Explanation:

According to the graph 40 Celsius degrees is the better condition for enzyme activity because it increases the rate of reaction.

The rate of reaction refers to the conditions in which an enzyme is working in order to convert given reactants into one or more products of such chemical reaction. This rate is very variable depending on the intrinsic properties of the enzyme and environmental factors that alter its activity.

In the image, we can observe that the enzyme has differential rates of reaction depending on the temperature.

Therefore, we can conclude that the rate of reaction of an enzyme largely depends on the condition in which the enzyme works such as in this case the temperature factor.

The salivary amylase does not function once it reaches the stomach after the good from mouth is passed to it.

Salivary amylase is an enzyme that breaks down carbohydrates right in the mouth. When it is passed to the stomach, the acidic ph of stomach denatures this enzymes and causes it to change it's shape. Consequently, the enzyme stops functioning.

Like most other enzymes, salivary amylase is a protein. At a pH between 6.5 and 7.0, it operates most effectively. More acidic or basic environments result in altered protein folding, which reduces the enzyme activity of the molecule.

The stomach's pH is typically between 1.0 and 2.0, which is very acidic. Salivary amylase's protein structure denatures and changes form at this pH level. As a result, when salivary amylase reaches the stomach, it is inactive.

Immunity is the ability of the body to fight against the foreign invaders and the disease caused by them. This immunity can be active or passive. Active immunity is the one that the body develops by itself. Passive immunity is the one that is introduced into the body by injecting antibodies.

Humoral immunity is the response mediated by the antibodies present in the body for specific pathogens. It is driven by the B cells. Antibodies are the Y-shaped structures that are produced by the B cells in response to the invasion of certain foreign invaders also called the antigens.

The object which is having greater mass will have greater KE if gravity is neglected. Cause kinetic Energy is directly proportional to the mass of the object.

Now on rolling down the slide the one which is rolled from a greater height will have greater potential energy will eventually have greater kinetic energy.

The energy that an object has as a result of its ongoing motion is known as kinetic energy in terms of physics. It is described as the effort required to move a mass-determined body from rest to the indicated velocity.

The body holds onto the kinetic energy that it acquires during this acceleration until and unless its speed changes. Kinetic energy has the following formula: K.E. = ½ m v2, where m is the object’s mass and v are its square velocity.

The kinetic energy that is measured in kilograms-meters then squared per second squared if this mass is then measured in kilograms and the velocity is then measured in meters per second.
