Answer:

42

Explanation:

If you divide the m/s and the frequency it will bring you to the wavelength of the sound.

1,470/35=42

42 is the wavelength of the sound.

The wavelength of a sound produced by the vocalization of a dolphin with a frequency of 35 Hz and a speed of 1,470 m/s would be 42 m

The speed or the velocity of a traveling wave is the product of its wavelength and its frequency. In other words:

V = λf, where V = speed/velocity, f = frequency, and λ = wavelength.

In this case, V = 1,470 m/s and f = 35 Hz

λ = 1470/35

      = 42 m

Answer:

Photosynthesis and cellular respiration are connected through an important relationship. This relationship enables life to survive as we know it. The products of one process are the reactants of the other. Note that the equation for cellular respiration is the direct opposite of photosynthesis:

cellular respiration: C 6 H 12 O 6 + 6O 2 → 6CO 2 + 6H 2 O

photosynthesis: 6CO 2 + 6H 2 O → C 6 H 12 O 6 + 6O 2

In both processes, energy is generated at the cellular level

Explanation:

Photosynthesis makes glucose that is used in cellular respiration to make ATP. Glucose is converted back to carbon dioxide, which is used in photosynthesis. While water breaks down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the oxygen released that is used by us and other organisms for cellular respiration. We breathe that oxygen, which is transported through our blood to all our cells. In our cells, oxygen allows it to process cellular respiration. Cellular respiration works best in the presence of oxygen. Without oxygen, much less ATP would be produced.

Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the path through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis takes carbon dioxide out of the atmosphere. The exchange of carbon dioxide and oxygen during photosynthesis (Figure below) and cellular respiration throughout the world help to maintain atmospheric levels of oxygen and carbon dioxide at a stable level.

Photosynthesis and cellular respiration are interrelated, photosynthesis captures sunlight to turn water and carbon dioxide into glucose and oxygen, while cellular respiration uses oxygen to break down glucose, thereby releasing energy and creating water and carbon dioxide. These processes complement each other, forming a cycle of energy conversion and matter recycling in ecosystems.

The relationship between photosynthesis and cellular respiration is quite intricate as they are interrelated, complimentary biological processes. Photosynthesis is a process that occurs in plants, where energy from sunlight is captured and used to convert carbon dioxide and water into glucose (a carbohydrate) and oxygen. On the other hand, cellular respiration is a process that happens in all living cells, where glucose is broken down in the presence of oxygen to produce carbon dioxide, water, and release energy.

Thus, the output products of photosynthesis serve as the input reactants for cellular respiration and vice versa, creating a sustainable cycle of energy conversion and matter recycling in the ecosystem.

One uses light energy absorbed by chlorophyll to produce organic molecules, while the other breaks down those molecules to harness the stored chemical energy. Plants being unique, contain both chloroplasts for photosynthesis as well as mitochondria for respiration. These reciprocal interactions between photosynthesis and cellular respiration make them powerhouse processes that allow organisms to survive, grow, and reproduce.

Answer:

All the possible alleles for a gene with multiple alleles cannot be expressed by single individual

Explanation:

Gene pool refers to the sum total of all the alleles of all the genes which are present in a population. Human beings are diploid organisms. One individual can have only two possible alleles for a gene. A gene can have two or more than two alleles. Since all the possible alleles for a gene with multiple alleles cannot be expressed by single individual, a gene pool cannot be made of one individual.

Answer: C. the output of one is the input of the other

Cellular respiration is interrelated with photosynthesis because the product of photosynthesis is a substrate for cellular respiration, hence option c output of one is the input of the other.

Photosynthesis is a light-dependent process to make metabolic product glucose for energy, a carbon-containing compound.

Cellular respiration is the process to extract energy from metabolic products and convert into the form of ATP, this ATP is used by cells as an energy currency.

Cellular respiration depends on photosynthesis for the metabolic substrate to extract energy during the process.

Therefore photosynthesis is related to cellular respiration, the output of one is the input of the other process, hence option c is correct.

The solution would be hypertonic.

A hypertonic solution is one where the concentration of solutes is greater outside the cell than inside.

Answer:

Outside it is hypertonic, whereas inside it is hypotonic solution.

Explanation:

We can classify the solution into three types:

Hypertonic, hypotonic and isotonic.

If a cell is placed in a solution where the concentration of solutes is more outside than inside, then the cell is said to be hypotonic with respect to cell exterior.

If a cell is placed in a solution where the concentration of solutes is less outside than inside, then the cell is said to be hypertonic with respect to cell exterior.

If the solute concentration is same both inside and outside the cell then the cell is said to be isotonic with the exterior solution.

Water always moves from low solute concentration to higher solute concentration across the semipermeable membrane to bring it to equilibrium.

Answer:

D

Explanation:

In water, an embryo can exist without desiccation hence remain viable until it is able to develop into another plant. On land, however, the embryo will be prone to desiccation and seeds are a plant’s adaption to survive life on land. The seeds have a pulp that provides the moist environment enclosing the embryo. In addition, seeds have a testa/seed coat that drastically lowers the rate of loss of water from the inside of the seed to the environment.

The production of seeds is the adaptation that allowed plants to exist on land. Therefore, the correct option is D.

The development of seeds enabled plants to reproduce and disperse their offspring without the need for water. The protection and nutrition provided by seeds to the growing embryo allows plants to settle and thrive in a wide variety of terrestrial habitats. This adaptation has helped plants to successfully colonize a variety of terrestrial ecosystems and has contributed significantly to the success and diversity of plant species on Earth.

Explanation:

Having a high biodiversity can help an ecosystem to survive a disturbance it doesn't decrease the chances of one happening.

High biodiversity increases the chances of an ecosystem surviving a disturbance and contributes to ecosystem stability.

Answer:

Biodiversity refers to the variety of living organisms in an ecosystem, including different species, genetic diversity, and ecological diversity. It plays a crucial role in maintaining the stability of ecosystems. High biodiversity increases the chances that an ecosystem will be able to survive a disturbance, such as a natural disaster or human activities. This is because different species have different roles and functions, and a diverse ecosystem is more resilient and adaptable to changes.

For example, in a forest ecosystem, a diverse community of plants, animals, and microorganisms interact and depend on each other. If there is a disturbance, such as a forest fire, a diverse ecosystem can recover more quickly because different species have different strategies for survival and can fill in the vacant ecological niches left by the disturbance.

In contrast, low biodiversity makes an ecosystem more vulnerable to disturbances. If an ecosystem has low diversity and one species is severely affected by a disturbance, such as a disease outbreak, the entire ecosystem can be destabilized. This can lead to a chain reaction, affecting other species that depend on the affected species, and ultimately leading to a collapse of the ecosystem.

Answer:

B. store excess carbon underground

Explanation:

The fossil fuels have been formed on the basis of organisms that have died, mostly producers. These organisms have carbon stored in them. As they died and got covered by sediments, the carbon has been stored in the lithosphere. Since more and more sediments have been covering the stored carbon, it has been isolated and stored into the lithosphere for tens or even hundreds of millions of years, thus contributing to lowering the amount of carbon in the atmosphere for quite some time, and removing it from its natural cycle.

The result of mutation during meiosis is that the offspring of the organism will have a mutation.

Meiosis is a proces by which cells divide in order to produce four other cells, each with half the full complement of DNA. Meiosis aims to produce gametes (eggs and sperm cells).  Errors may take place during meiosis giving way to gametes with an extra or missing chromosome.

During the process of meiosis, chromosomes are replicated once in S phase (just like mitosis) into sister chromatids, but the cell divides twice.

The meiotic mutations are associated with genetic recombination and depend on double-strand breaks that initiate crossing over.

In biology, a mutation is an alteration in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal DNA. Viral genomes contain either DNA or RNA. Mutations result from errors during DNA or viral replication, mitosis, or meiosis or other types of damage to DNA (such as pyrimidine dimers caused by exposure to ultraviolet radiation), which then may undergo error-prone repair cause an error during other forms of repair,or cause an error during replication .

Mutations may also result from insertion or deletion of segments of DNA due to mobile genetic elements.Meiotic mutations cause genetic recombinations and are dependent on the breaks which occur on the double strands.

Thus,the  result of a mutation during meiosis is genetic recombination.

C. The concentration of calcium in the myofibril must decrease.

Explanation:

As soon as the stimulus which causes myofibril to contract stops, its time for muscle to relax.  

A low calcium level in the sarcoplasm is the utmost requirement of muscle relaxation otherwise sliding of myosin will continue and muscle will keep on showing contraction. In order for muscle contraction, calcium ion i.e. Ca²⁺ must come out of the sarcoplasmic reticulum so for relaxation reverse process occurs i.e. Ca²⁺ is pushed back to the sarcoplasmic reticulum. There are many pumps known as "calcium pumps" which facilitate this process. Now, the concentration of Ca²⁺ becomes comparatively low in the sarcoplasm which causes troponin C to detach from Ca²⁺. Their detachment causes actin and myosin to detach from each other too which finally leads to muscle relaxation.
