How do the levels of thermal energy and speed differ between low- and high-friction surfaces?

Answer:

For an instance, an aquatic food web can be connected to a food web that is based on land. Planktons and algae are some of the main producers which are found in the marine ecosystem. These planktons are eaten by a tiny shrimp called krill. Whales, seals, squids and fishes feed on these tiny shrimps.

Answer:

357,250,000 -> 35,725,000 -> 3,572,500 -> 357,250 -> 35,725

Explanation:

only 10% of the energy at one level gets passed to the organism in the next level.

hope this helps :)

At every level in the energy pyramid, 10% of the energy reduces from producers to quaternary consumers.

Energy pyramid is the flow of energy.

Reduces mean decreases.

Producers are the plants which can prepare food by themselves.

Quaternary consumers are the top most predators which consumes tertiary consumers.

So there are five energy levels in a pyramid. they are producers in which the energy is 357,250,000 KC, primary consumers (35,725,000 KC), secondary consumers (3,572,500 KC), tertiary consumers (357,250 KC) and quaternary consumers ( 35,725 KC).

C. Each pruning method was used on only one shrub.

Explanation:

Reproducibility is one of the most important factors contributing to the reliability of scientific research. The researcher must be able to achieve the same results two to three times. In biological research, this is usually done in the from of triplicates i.e. one experiment is repeated three times. This is done for two reasons:

Triplicates rule out the possibility that the observed change was caused by another factor or through mere chance. Therefore, in the current scenario, each pruning method should have been applied to multiple (at least 3) samples of a shrub.

Some characteristics of Nematoda phylum are:

1) Their body structure is triploblastic, bilaterally equal and cylindrical in shape.

2) They show a tissue-level organization.

3) Their body keeps a pouch or pseudocoelom.

Answer:

Metaphase

Explanation:

Taxol is an anti-mitotic chemical which is used to treat cancer.

The taxol act by binding the microtubules which act as cytoskeletal structure. The microtubules are involved in the segregation of the chromosomes during the division of the cell.

The microtubules allow the movement of the chromosomes in the dividing cell during anaphase.

If the cells are treated with the taxol then the cells will be observed at the metaphase in which the chromosomes are aligned in the equatorial line. The microtubules will separate the chromosomes after the metaphase or during the anaphase but since the taxol prevents the depolymerization of the microtubules, therefore, cells are found in the metaphase.

Thus, Metaphase is correct.

Answer:

primase - unwinded parental double helix DNA, no replication.

DNA ligase - new double helix DNA, one old strand and okazaki fragments

DNA polymerase 1 - original DNA strands, daughter strands with primers still attached.

Explanation:

The primase enzyme is responsible for the synthesis of RNA primer which binds with unwinded DNA strands at the origin of replications and serves as a starting chain for the daughter strands. Hence, their absence during replication will lead to the discontinuation of the replication process after the unwinding of the double helix structure by the helicase enzyme.

DNA ligase functions as to join fragments of DNA synthesized discontinuously (okazaki fragments) during replication. Okazaki fragments are generated after replication of the leading and the lagging strands have been complete. Hence, the absence of the DNA ligase will result in the lagging strands existing as a lone strand along with the okazaki fragments and a newly replicated DNA consisting of one old leading strand and its newly synthesized complimentary strand.

The DNA polymerase 1 is responsible for the removal of RNA primers and replacing them with DNA nucleotides after the elongation process. Hence, the absence of the enzyme will cause incomplete replication process.

Answer:

42

Explanation:

The somatic chromosome of zebras will be 42.

During gamete formation prior to fertilization, reproductive cells divides by meiosis to give rise to haploid cells with half the number of chromosomes of the somatic cells.

During fertilization, two haploid gametes fuse together to give rise to a diploid zygote.

A donkey with 62 somatic chromosome will produce gametes with 31 chromosomes. Zonkey is a diploid organism and has chromosome number of 52, hence, the haploid gamete of zebra would have:

52 - 31 = 21 chromosomes.

Hence, the diploid (somatic) chromosome number of zebras will be:

21 x 2 = 42 chromosomes.

Each lung enclosed in two membranes called the pleurae . The outer membrane is called parietal pleura , and the inner membrane is called visceral pleura , which closely invest the lungs . A very narrow space exist between two pleura i.e., known as pleural cavity that contains pleural fluid secreted by the pleurae .  Pleurae cause the production of pleural fluid and create cavities that seperates organ . Mesothelial cells of  both pleural layer secretes fluid and cause lubrication on the surface . These lubrication mimize the friction between  pleural layer to prevent the difficulty in breathing and creates surface tension that  is responsible for holding the lungs to the thorax wall . Generally , pressure within cavities present between pleural layers is less than atmospheric pressure i.e., negative pressure in the pleural cavity which is also  responsible for holding the lungs to the thorax wall .

Final answer:

The mRNA sequence that is complementary to the DNA sequence GATCAC is CUAGUG, corresponding to option 1 in the multiple-choice question provided. This is determined by pairing each DNA base with its RNA complement following the transcription rules.

Explanation:

The student's question asks which mRNA sequence is the complement to the DNA sequence GATCAC. The transcription process in biology involves creating a complementary RNA strand from a DNA sequence. Each DNA base pairs with a specific RNA base: adenine (A) pairs with uracil (U) in RNA, thymine (T) pairs with adenine (A), cytosine (C) pairs with guanine (G), and guanine (G) pairs with cytosine (C).

Using these pairing rules, we find the complementary RNA sequence for the DNA sequence GATCAC as follows:

DNA: G

mRNA: C

DNA: A

mRNA: U

DNA: T

mRNA: A

DNA: C

mRNA: G

DNA: A

mRNA: U

DNA: C

mRNA: G

Therefore, the correct mRNA sequence that is complementary to GATCAC is CUAGUG, which corresponds to option 1.

The immune response is the body's defense mechanism against foreign substances, involving various immune cells and processes to identify, neutralize, and eliminate pathogens or abnormal cells.

The immune response is a complex series of physiological processes and mechanisms by which the body's immune system recognizes and defends against foreign substances, such as pathogens (e.g., bacteria, viruses), toxins, or abnormal cells. It involves a coordinated effort of various immune cells, including white blood cells, antibodies, and chemical messengers, to identify, neutralize, and eliminate these foreign invaders. The immune response includes both innate immunity, which provides immediate but non-specific defense, and adaptive immunity, which is specific and can develop memory to better respond to future encounters with the same pathogen. Overall, the immune response plays a critical role in protecting the body from harmful substances and maintaining overall health and well-being.

The sagittal plane, which divides the body into left and right halves, is the only anatomical plane that could not show both structures or regions like the brain and tongue, both eyes, hypogastric and gluteal regions, both kidneys, sternum and vertebral column, or the heart and uterus.

To answer your question, let's first recall what each anatomical plane represents. The sagittal plane divides the body into left and right halves, the frontal (or coronal) plane divides the body into front (anterior) and back (posterior) portions, and the transverse (or horizontal) plane divides the body into upper (superior) and lower (inferior) halves.

Given this understanding, we can deduce that the sagittal plane is the only one that cannot show: (a) both the brain and tongue, (b) both eyes, (c) both the hypogastric and gluteal regions, (d) both kidneys, (e) both the sternum and vertebral column, and (f) both the heart and uterus. This is because these structures or regions are located on opposite sides of the body (left and right) and not vertically or anterior-posteriorly.

Answer:

Their ability to manufacture their own food

Explanation:

There are two main types of plankton. this includes phytoplankton and zooplankton. Phytoplankton are different from zooplankton in that these plankton are plant-like and undergo photosynthesis manufacturing their own food. They are also regarded as being autotrophic. They are important in that other organisms including the zooplanktons depends on them for food, hence they can also be categoriZed as producers.

"Phytoplankton are distinguished from other types of plankton primarily by their ability to photosynthesize. They contain chlorophyll and other pigments, which allow them to convert light energy into chemical energy through the process of photosynthesis.

This sets them apart from zooplankton, which are heterotrophic and must consume other organisms for energy, and bacterioplankton, which are primarily decomposers.

The importance of phytoplankton is multifaceted:

1. Oxygen Production: Phytoplankton contribute significantly to the oxygen in our atmosphere. It is estimated that about 50% of the global oxygen production is due to phytoplankton photosynthesis, making them crucial for the survival of aerobic life on Earth.

2. Basis of Marine Food Webs: As primary producers, phytoplankton form the foundation of the marine food web. They are consumed by zooplankton, which in turn are food for larger organisms, including fish, whales, and birds. Thus, they support the immense biodiversity of marine ecosystems.

3. Carbon Sequestration: Phytoplankton play a key role in the global carbon cycle. Through photosynthesis, they absorb carbon dioxide from the atmosphere. When phytoplankton die, some of their biomass sinks to the ocean floor, effectively sequestering carbon away from the atmosphere and mitigating climate change.

4. Regulation of Climate: Phytoplankton can influence climate patterns by affecting the heat distribution in the ocean. They can also impact cloud formation and albedo through the production of dimethyl sulfide (DMS), which can lead to the formation of clouds that reflect sunlight away from the Earth's surface.

5. Economic Value: Phytoplankton are the starting point for many commercially important fisheries. Their productivity affects the abundance and distribution of fish stocks, which are vital for the economies of coastal communities and the broader seafood industry.

In summary, phytoplankton are a critical component of Earth's ecosystems, influencing atmospheric composition, climate regulation, marine biodiversity, and human economies. Their health and abundance are indicators of the overall health of the world's oceans."
