6. What disease is caused by the ameba? First person ro get right answer gets mark as brainliest.​

When an electron has been excited to a higher energy state, excited electrons are transferred to electron acceptors in the chloroplast.

An electron can return to its original level after being stimulated to a higher energy state and reemit the light as fluorescence. Chlorophyll fluoresces brightly when exposed to a strong red or blue light after being extracted in solution. However, there is no fluorescence when the red or blue light is turned on and the chlorophyll is contained inside chloroplasts. This suggests that energized electrons are likely transported to chloroplast electron acceptors.

The rate of change of the volume of the balloon (sphere) is 150π cubic cm/min. The formula for the volume of a sphere is given by; V = (4/3)πr³.

Given that the circumference of a balloon (sphere) is increasing at a rate of 3π cm/min and the radius is 5 cm, we have to find the rate of change of the volume of the balloon. We know that the formula for the volume of a sphere is given by; V = (4/3)πr³. Differentiating with respect to time gives; dV/dt = 4πr² × dr/dt

We know that the circumference of a sphere is given by; C = 2πr

Differentiating with respect to time gives; dC/dt = 2π × dr/dt

Now we can find the value of dr/dt from the above expression; dr/dt = dC/dt ÷ 2πPutting the given value in the above expression, we have ;dr/dt = 3π ÷ 2πdr/dt = 3/2 cm/min

Now substituting the value of r and dr/dt in the expression for dV/dt; dV/dt = 4πr² × dr/dt dV/dt = 4π(5)² × (3/2) dV/dt = 150π

Therefore, the rate of change of the volume of the balloon (sphere) is 150π cubic cm/min.

The joint that moves only by a uniaxial movement around its own axis is the pivot joint.

A pivot joint is a type of synovial joint that allows for rotational movement around a single axis.

In a pivot joint, one bone has a cylindrical projection that fits into a ring or notch in another bone, allowing rotational movement around a single axis. Pivot joints are also known as rotary joints.

In this type of joint, one bone rotates around another bone's axis, allowing only one movement, such as rotation. An example of a pivot joint in the human body is the joint between the atlas and axis vertebrae in the neck, which allows us to rotate our heads.

Answer:

Flood Erosion and Deposition: As flood waters rise, the slope of the stream as it flows to its base level (e.g., the ocean or a lake) increases. Also, as stream depth increases, the hydraulic radius increases thereby making the stream more free flowing. Both of these factors lead to an increase in stream velocity.

Explanation:

Flood erosion and deposition, as flood waters rise, the stream's slope rises as it descends to its base level, which may be an ocean or a lake.

Additionally, when stream depth rises, the hydraulic radius rises as well, increasing the stream's ability to flow freely, these two elements cause the stream velocity to rise.

The volume of water flowing into a stream channel from the watershed directly affects the stream's flow. The weather has an impact on it; it rises during downpours and falls during dry spells.

The force of gravity, which pushes water downhill, is what gives moving river water its energy. A river will flow more quickly and with greater energy at a higher slope.

Therefore, flood erosion and deposition factors will increase the rate of a stream’s flow.

Answer:

This can happen through the rock cycle. But there are 3 processes which are crystalization, erosion and sedimentation, and metamorphism.

Explanation:

There are several types of rocks, but only one large furnace in which parts of a single large rock are cooked and changed into the various types of rocks. Our planet is a massive rock and a massive furnace. All rocks are divided into three categories, or classes. They're classified as sedimentary, metamorphic, or igneous, with variances in how they're generated.

I'll show you a schematic of the Rock Cycle instead of a detailed answer. It shows how one type of rock may be converted (metamorphic) into another under certain conditions. Just bear in mind that some types of rocks, such as sedimentary rocks, may form in a matter of hours, while others, such as metamorphic rocks, take millions of years to create.

The following best describes the role of cell-to-cell communication during a response to an invasion of antigens - d. Chemicals that are secreted from antigen-presenting cells then activate helper T cells.

Immune cells can interact with one another by directly attaching to receptors on their surfaces or by releasing substances that stimulate a response.

Immune cells, such as APCs, produce proteins known as cytokines and chemokines, which flow away and bind to the surface of a nearby or distant cell.

Antigens are processed by APCs and presented to T lymphocytes.

They bind to the antigen and activate t-cells, allowing them to quickly detect and destroy them by secreting chemicals.

As a result, the following best captures the role of cell-to-cell communication during an antigen invasion response - d. Helper T cells are activated by chemicals released by antigen-presenting cells.

The morphological tree structure for the word "inflammable," which means "able to catch on fire easily," can be represented given below.

The morphological tree structure for the word "inflammable" reflects its composition and meaning. The word can be divided into two morphemes: "in-" and "-able." The prefix "in-" functions as a negation, indicating the opposite or absence of a particular characteristic. In this case, it negates the meaning of "flammable" which denotes the ability to catch fire easily. The suffix "-able" is added to the base form "flammable" to indicate the capability or possibility of the root word.

                            inflammable

                                  /      \

                            in-            -able

                             /                  \

                          not              capable

The morphological tree structure represents the hierarchical relationship between the morphemes in the word. Starting from the root node "inflammable," the tree branches out into two branches: one for the prefix "in-" and another for the suffix "-able." The prefix "in-" leads to the morpheme "not," indicating the negation of the base word "flammable." The suffix "-able" leads to the morpheme "capable," signifying the ability or possibility of the root word.

By breaking down the word "inflammable" into its constituent morphemes, the morphological tree structure helps to understand the formation and meaning of the word.

Explanation:

In general, it is not possible to determine the type of cell division that has just taken place based solely on the chromosome number (2n or n) of the resulting cells. This is because both mitosis and meiosis can result in cells with a 2n or n chromosome number, depending on the specific stage of the process that is being observed.

During mitosis, a cell undergoes a single round of DNA replication followed by one division, resulting in two identical daughter cells, each with the same chromosome number as the original parent cell. In most cases, this means that the daughter cells will have a 2n chromosome number, since they contain the same amount of genetic material as the parent cell.

During meiosis, however, a cell undergoes two rounds of division, resulting in the production of four genetically diverse daughter cells, each with half the chromosome number of the original parent cell. This means that the resulting cells will have an n chromosome number, which is half of the 2n chromosome number of the parent cell. However, it is important to note that in some cases, cells may undergo meiotic divisions but still retain a 2n chromosome number (as is the case with certain plant cells).

Thus, while the chromosome number of a cell can provide some information about the type of cell division that has taken place, it is not a definitive indicator and must be considered in the context of other factors, such as the specific stage of the cell cycle, the type of cell undergoing division, and the presence or absence of homologous chromosomes.

The embryonic period of prenatal development occurs from week 3 until week 8 and is characterized by rapid organ formation and differentiation in the developing embryo, laying the foundation for major body systems.

The embryonic period of prenatal development spans from week 3 until week 8 of gestation. It is a crucial stage characterized by rapid and significant growth and differentiation of the developing embryo. During this period, the major organ systems begin to form and develop. The heart starts beating, and the circulatory system begins to take shape. The neural tube develops, laying the foundation for the central nervous system. Limb buds emerge, and the basic structures of the head, face, and other body parts begin to form. By the end of the embryonic period, the embryo has recognizable human features and has established the groundwork for further growth and development in the fetal period.

Some mutations can change genetic variation in a way where an organism can adapt to the surrounding environment. Mutations created gills, which allow fish to breath underwater. Mutations allowed giraffes to reach leaves higher up on trees so they can get food. Mutations also allowed humans to be able to adapt to any environment and situation and continue growing.

Explanation: Brainliest is always appreciated

Mutations are random changes in the DNA sequence of an organism's genome. Mutations can be beneficial to an organism because they can lead to genetic variation, which can allow for natural selection to occur.

Mutation is a process that refers to a change in the genetic material (DNA) of an organism. The genetic material carries the information that determines an organism's characteristics and traits, like eye color, hair color, or susceptibility to certain diseases. Mutations can happen naturally, or they can be induced by various factors such as exposure to radiation, chemicals, or viruses.

Mutations can affect a single base pair of DNA, a larger segment of DNA, or an entire chromosome. They can be classified in many ways, but one of the most common ways is by their effect on the genetic material.
