There are four types of tongue papillae: (1) filiform, which is thin and wired shape and no taste buds, (2) fungiform, which is mushroom-shaped near the middle and with taste buds, (3) foliate, which is leaf-shaped near the sides and with taste buds, and (4) circumvallate papillae, which is whorls at the sides and with taste buds.

ANSWER: TRUE. There are taste buds in the fungiform and circumvallate papillae.

The cell has several types of membrane transport alternatives, being the simple diffusion, facilitated diffusion, and active transport one of the options for the cell to exchange molecules between internal and external environment.

The types of cell transport:

1 - Simple Diffusion: is a process that does not need energy (passive), used to transport small and nonpolar molecules from a region of higher concentration into a region of lower concentration (in the gradient concentration direction);

2 - Facilitated Diffusion: is a process that does not need energy (passive), used to transport larger ions and polar molecules with the help of carrier proteins or pore proteins (transport proteins);

3 - Active Transport: There is two types of active transport, primary active transport is used for molecules moving against their gradient coupled to the hydrolysis of ATP, and secondary active transport is for molecules going with more molecules against their gradient. It is a process that needs energy (active) to happen, going always against the gradient of concentration of the cell.

The biological molecule composed of elements C, H, O only is:  (2) carbohydrate.

Biological molecules are the organic polymers present inside the body that help in the proper maintenance and functioning of the body. The major biological molecules present inside the body are: carbohydrates, proteins, nucleic acids and lipids.

Carbohydrate is a polyhydroxy ketone or aldehyde. They are of three types: monosaccharides, disaccharides and polysaccharides. Mono saccharides are the basic monomeric unit that form the di- and poly-saccharides. They serve several functions like structural, energy, food, etc. Examples are glucose, starch, glycogen, etc. It is a very essential nutrient in foods.

Keeping birds from becoming tangled in fishing line.

The process is non-spontaneous and causes an increase in entropy.

The process is not automatic even thoug it involves transportation of materials in a cell. There is a change in the amount of free energy but there is entropy.

Hip joint: It has the presence of ligaments that provides it strongness and musculature. because of these ligaments, allows the 180° movements of the legs. As the leg is used for running or much more physically intense activities the joint between the pelvis and femur that is the ball and socket joint gets so much pressure and stress, but due to its strong reinforcement by the ligaments, it becomes more flexible and strong.

Shoulder joint: As it is located in the scapula and also has the ball and socket joint it provides mobility as we can stretch our arm, and use it for throwing many things so this shows that it has mobility, but this reduces the stability by causing the rotatory injuries. Always remember that shoulder is in the shoulder blade which is mobile and this makes it risky and susceptible to injuries.

Conclusion: The scapula has mobility and we can see the upward and downward movement in it so this makes the shoulder joint more mobile but less stable as compared to the hip joint which has more stability.

Protozoans like paramecium have protoplasmic invasions called gullets, which aid in these species' food uptake and digesting.

Protists have eukaryotic cells, as opposed to bacteria, these organisms feature cytoplasmic membrane-bound components as well as a nucleus that is membrane-bound.

Another kind of protists is zooflagellates, they resemble animals and use flagella to move. Flagella are whip-like organelles that rapidly spin and help an organism move through the water like a boat's propeller.

The majority of zooflagellates have one to eight flagella that aid in movement, protists do not belong to a monophyletic group of creatures.

Therefore, The paramecium's gullet functions as the buccal cavity where food is transformed into food vacuoles for digestion.

The complete chart indicating the number of chromosomes after meiosis, in body cells, in gametes and after mitosis are indicated in the given image.

Meiosis is the process of cell division in which the number of chromosomes are reduced to half. This is the reason why it is also called the reductional division. The process occurs in two phases: Meiosis I and Meiosis II. Meiosis I is the phase where actual reduction takes place.

Mitosis is the process of cell division where the daughter cells are identical to the parent cell. Here, the number of chromosomes remain the same and hence is called equational division.

Here we are comparing the DNA sequence of the gene for skin pigment in a normal gorilla (sample 1) and an albino gorilla (sample 2).

The sequences are the following:

Sample 1

ATT ACA GTA CTG GCA

Sample 2

ATT ACA ATA CTG GGC A

We can see that the sequences have different lengths, sample 1 has a length of 15 base pairs (bp), while sample 2 has 16 bp. This means there is an extra nucleotide, so this is an insertion mutation.

This means the correct answer is C. Insertion

An organism that contains genetic material that has been isolated from another organism and inserted into it by biotechnological tools is known as a transgenic organism, and this is usually done to produce organisms that have a desired genome to, for example, have a resistance to some pathogens that could harm it otherwise, such as plagues, and this is because the inserted DNA produce a genetic output in terms that the organisms can now produce proteins that before it couldn't.

We can see this process currently used in the agricultural industry, where some plants have external genetic material in them, such as tomatoes or apples.

Transgenic refers to an organism or cell whose genome has been altered by the introduction of one or more foreign DNA sequences from another species by artificial means. Transgenic organisms are generated in the laboratory for research purposes.

Answer: The Ocean

Explanation: The ocean contains a vast amount reservoir of carbon this is because of the organisms in the ocean that take carbon dioxide.

Larger DNA molecules travel more slowly across the gel matrix during electrophoresis than smaller ones do. As a result, the DNA molecules divide into different bands according to their respective sizes. The quantity of DNA that builds up in a band determines how black the band is.

Because DNA is negatively charged, it gravitates toward the positive electrode. All DNA fragments flow through the gel at the same speed because they all have the same mass-to-charge ratio.

A PCR result must frequently be further altered by cleavage with restriction enzymes. Without any DNA purification, restriction enzyme digestion may be carried out quickly and easily right in the PCR mixture.

The PCR primers' structure determines the size of the PCR result. To amplify an area of interest from a double-stranded DNA template, the user designs PCR primers. Always two primers are present, and they are made to border the area.

Answer: Substrate.

Explanation: It enters the active site of the enzyme.

The rain will be able to run off more quickly on concrete and in a vast field, which will probably cause flooding in both areas.

The continual movement of water on, above, and below the Earth's surface is referred to as the water cycle, also known as the hydrologic cycle or the hydrological cycle.

Concrete is less porous than soil, thus the water won't be able to seep back into the soil. The volume of water in subsurface aquifers would decrease as a result.

Additionally, the rain will be able to run off more quickly on concrete and in a vast field, which will probably cause flooding in both areas. Both of these would probably hasten the water cycle and have detrimental consequences for people.

The bloodstream receives oxygen from the lungs during gas exchange. Carbon dioxide leaves circulation enters the lungs. Between the alveoli and network of tiny blood arteries known as capillaries are the lungs.

The waste gas carbon dioxide is exchanged for oxygen at each cell in your body. This waste gas is then transported by your bloodstream back to your lungs, where it is expelled after being eliminated from the bloodstream. Gas exchange, a crucial activity carried out automatically by your lungs and respiratory system, is a fundamental function.

While carbon dioxide diffuses into the alveoli and is later breathed out of the body, oxygen diffuses from the alveoli into the capillaries, which carry it out of the lungs and to the rest of the body. The respiratory membrane serves as a barrier for the exchange of oxygen and carbon dioxide.

Within an ecosystem, there are different components that are part of it and that work together, and this interaction, ideally, creates an equilibrium in the ecosystem.

In the picture, we can see one abiotic factor such as the sun, that it's fundamental to the development of some biotic factors such as the producers. Some other abiotic factors could be water or minerals on the soil that plants use to survive. Later on, in the food chain, we can see how different types of biotic factors interact, being the producers eaten by the primary consumers, and so on. When the biotics factors die, they are decomposed by the decomposers such as fungi, producing organic and inorganic matter, closing the cycle.
