What observations can a geologist make by working Outdoors instead of in a lab?

Answer:

Nucleus

Explanation:

The correct answer would be the nucleus.

The nucleus is a double membrane organelle that is found in all eukaryotic cells but not in prokaryotic cells. It contains the chromosomal hereditary material of eukaryotic cells and serves as the control center of the cell where other cellular activities are dictated.

The chromosomal hereditary materials of prokaryotic cells lie freely within the cytoplasm unlike what is obtainable in eukaryotic cells. The materials are package in a condensed fashion within the eukaryotic nucleus to form a structure known as chromatin. During cell division, the chromatin decondenses and become visible under the microscope as chromosomes.

Freshwater and marine regions make up the aquatic biome. The concentration of salt in freshwater areas like lakes and rivers is low. Salt concentrations are higher in marine areas like oceans and estuaries. They are arranged in descending order of size organism, population, community, and ecosystem.

The biological progressive aquatic system alludes to the collaboration of living beings with their current circumstance and prompts the development of a gathering of creatures. It is gathered into four levels: individual, populace, local area, and biological ecosystem level.

1A)a reason for phycoerythrin being absent from the Porphyra chromatogram is that

the pigment didn't dissolve/ was insoluble when the pigments from the algae were extracted

1B) Also, the pigment was not moved by solvent

/ was insoluble in the solvent used to separate the pigments

2A) orange/yellow/green/blue/violet can be the colour of light that will be absorbed efficiently by phycoerythrin.

R-phycoerythrin (R-PE), a red algal pigment complex, was isolated and refined from the recently discovered red alga Colaconema formosanum. Then, its bioactivities were looked into. It was shown that R-PE treatment significantly increased the vitality of the mammalian cell lines (>70%) but had no effect on the morphology of NIH-3T3 cells. It had less of an impact on the production of IL-6 and TNF- in lipopolysaccharide-stimulated RAW264.7 cells.

A significant amount of R-PE can be extracted from the crude P. haitanensis unclarified extract using the scalable technique outlined in this procedure. The value of this China-specific endemic Porphyra is increased by the high protein recovery method, which also speeds up the processing process and lowers expenses.

One weakness of Darwin's theory was that it lacked an explanation for how evolution occurs and is therefore denoted as option C.

This is referred to as the change in the heritable characteristics of biological populations over successive generations and makes organisms better suited for their ever changing envrironment.

Darwin's theory of evolution on the other hand describes how organisms evolve over generations through the inheritance of physical or behavioral traits but lacked an explanation for how it occurs and it was termed the theory of evolution by natural selection.

It had an explanation about adaptations, competition and genetic inheritance of traits which is the treason why option C was chosen as the correct choice.

Answer:

The right lung is smaller than the right to make room for the heart.

Explanation:

so the answer is A :)

The left lung contains two lobes while the right lung contains three lobes. Therefore option E is correct.

The statement that the left lung contains two lobes while the right lung contains three lobes is correct.

The right lung is divided into three lobes: the upper lobe, middle lobe, and lower lobe. On the other hand, the left lung is divided into two lobes: the upper lobe and lower lobe.

This anatomical difference is due to the position of the heart, which is located more towards the left side of the chest. The presence of an additional lobe in the right lung allows for a better fit around the heart.

Understanding the lobes of the lungs is important in assessing and diagnosing respiratory conditions and in surgical procedures that involve lung resection or transplantation.

Therefore option E The left lung contains two lobes while the right lung contains three lobes is correct.

It is hard to regain a trait that has been lost because the genetic changes required to evolve a new trait or to regain a lost trait are often complex and can involve multiple genes and regulatory elements. Furthermore, evolution is a slow, laborious process that requires beneficial mutations to accumulate over many generations.

When a trait disappears, the genetic material encoding it may also disappear or become inactive, making it more challenging for the trait to reappear in subsequent generations. For example, restoring a species' ability to manufacture a specific enzyme required for a particular metabolic pathway can be challenging if the genetic changes required to do so are complex.

Answer:

Cell wall, chloroplast, vacuole. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.

Explanation:

The main difference between plant cells and animal cells are cell wall and chloroplast , whereas for the vacuole plants have a vacuole called vescile which is not the same as the vacuole in plant cells.

Vacuoles are very large as they are needed to store water and they mostly contain water and sugars . On the other hand, vesicles are small and contain water, nutrients, enzymes, wastes, solution of water or food etc. This is the key difference between vacuoles and vesicles. hope it helps :)

The correct answer is A. Feedback mechanisms and homeostasis are closely related in that feedback mechanisms help to maintain homeostasis in living organisms. (option-a)

Homeostasis is the process of maintaining a stable internal environment despite external changes. Feedback mechanisms are the physiological responses of an organism to maintain this stability. For example, if the body temperature drops, the feedback mechanism in the body responds by shivering to generate heat and maintain the internal temperature. Similarly, if the body temperature rises, the feedback mechanism in the body responds by sweating to cool down and maintain the internal temperature. In both cases, the feedback mechanism works until the internal conditions return to normal, thereby maintaining homeostasis. Therefore, feedback mechanisms are essential for the maintenance of homeostasis in living organisms.(option-a)

Applying petroleum jelly over the leaf would not affect the rate of transpiration because stomata are located under the leaves. Stomata are the structure utilized by the cell to release water during transpiration. But applying petroleum jelly underneath the leaf would block stomata, reducing the rate of transpiration to the point of killing the plants, even if they are being supplied with water and sunlight.

Petroleum jelly would stop the stomata cells from losing moisture. Consequently, the rate of transpiration would slow down.

The rate of evaporation from the leaf surface and the rate of transpiration are closely related. The rate at which water evaporates from a leaf's surface rises with increased air movement across its surface (for example, from a fan). This occurs because the water-saturated air is expelled, enhancing the osmotic gradient.

Regarding the relative adjustments caused by coating the top and bottom surfaces of leaves with an impermeable substance like petroleum jelly, this is a matter of plant anatomy. Stomata are exclusively found on the underside of leaves in the majority of plants. This will keep them from becoming "clogged" during rain and out of the sun to reduce water loss (again more sunlight on the stomata would increase the rate of evaporation). As a result, a plant with covered undersides would transpire at a significantly slower rate than one with covered top surfaces.

Other elements that could impact the transpiration rate include:

Answer and Explanation:

Through many media sources, it is seen that people can "override" the human reflex action.

The way those people are able to be seemingly unaffected by actions and objects that would normally make others flinch or react is by training themselves to be unaffected. They may still feel pain but won't instantly react to the pain.

For example, everyone will feel pain to a boiling hot mug of tea. For many, when they touch the mug, they will pull their hand/finger away due to the intense heat the mug has. For those who trained to not reflex, they may be able to hold on longer than most others to the mug of tea. Even so, they may still pull away from the mug as it is hurting their hand.

In September the earth will be experiencing  an equinox

Equinoxes occur between March and September. When the Sun's rays strike the equator at midday and at a 90° angle, it is considered an equinox.  It stands for the idea that day and night have equivalent lengths. The sunset and dawn are separated by 12 hours everywhere on Earth. One may observe how quickly the sunset and dawn hours shift throughout the day the farther one goes from the equator.

Whereas, solstices occur in June and December. The contrary is visible close to the solstices. For a few days, both the sunset and sunrise appear to be constant. Over the course of the year, the time of day when the sun is directly overhead where one lives also gradually changes.

Answer:

No

Explanation:

No, plants do not take in air with their roots. Roots are designed to absorb water and minerals from the soil. In order to get the air and carbon dioxide they need for photosynthesis, plants have specialized structures called stomata in their leaves and stems that allow air to enter and exit. These stomata regulate the movement of gases into and out of the plant, so the plant can take in the carbon dioxide it needs and release the oxygen it produces.

Enzymes which covalently connects segments of DNA is v)primase. So, correct option is v.

Primase is a catalyst that blends short RNA groupings called groundworks. These preliminaries act as a beginning stage for DNA union. Since primase produces RNA particles, the protein is a kind of RNA polymerase. Primase capabilities by integrating short RNA groupings that are reciprocal to a solitary abandoned piece of DNA, which fills in as its format.

Primase is important that groundworks are blended by primase before DNA replication can happen. This is on the grounds that the chemicals that incorporate DNA, which are called DNA polymerases, can join new DNA nucleotides to a current strand of nucleotides. Hence, primase serves to prime and establish a groundwork for DNA blend.
