Explanation:Each drum must endure for one-half a second, so the period is 0.5 s. If the woodpecker drums upon a tree 4 times in one second, then the frequency is 4 Hz; each drum must endure for one-fourth a second, so the period is 0.25 s.

Answer:

The greater the difference in concentration, the quicker the rate of diffusion. The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly. The greater the surface area, the faster the rate of diffusion.

The function of light that allows the greatest magnification by a microscope is the transmission. The correct option is e.

Transmission of light is when light transmits through a transparent or translucent object it gets transmitted through it and when light is transmitted it is either refracted or scattered.

Light is electromagnetic radiation. It is an agent by which we are able to see the various objects near us. When light transmits through an object, the light which is of the color of the object gets absorbed and all other colors will reflect.

Magnification is an increase in the size of an object through a magnification glass. Light plays an important role in this, due to the transmission of light through the glass, it looks bigger.

Thus, the correct option is e. transmission.

Answer:

The population history of the island remains highly controversial. In addition to internal conflict, the population crash has been attributed to “ecocide,” in which the Island's resources were exhausted by its inhabitants, reducing its ability to support human life.

Explanation:

Europeans was known to discovered Easter Island in 1722 and it's name was given by Captain Admiral Jacob Roggeveen.

The human population growth had a negative effect on the Easter Island.

The ecocide hypothesis is the one explanation to how the human population increased exponentially since its colonization and as such

Human populations did over increased the carrying capacity of the Island to support sustainable crops, and in consequence, the island was severely deforested.

The island's natural cycling of matter and energy also reduced or change and as such the people fought among themselves for scarce resources of the island. They had little food and were starving and they resorted to cannibalism.

The island was also plaque by blackbirding from 1862 to 1863.

C: Reproduction keeps the animals from becoming extinct.

The similarly alongside the cladogram you move,the greater variations in DNA the organisms have compared to the common ancestor.

A cladogram has been an evolutionary tree that diagrams the ancestral relationships amongst organisms. DNA sequence analysis of the hemoglobin alpha gene shows that humans and chimpanzees have a more similar sequence to each other than they do to the gorilla’s DNA sequence.

Analogies structure has been body parts that have a similar function but differ in structure. All vertebrate embryos have a tail and gill slits at some point during embryonic development.

Answer:

most at of earth s water is salt water found in oceans

Photosynthesis is a process carried out in plant cells that serves to synthesize sugars such as glucose which can later be used to form other important molecules such as cellulose.

Photosynthesis requires energy from sunlight, carbon dioxide (CO2) and water to obtain glucose and oxygen as products. Sunlight provides the ATP to carry out the reactions, water provides electrons and CO2 provides the carbon needed to build the sugar.

False. The lysosome is the site of synthesis of various large biological molecules.

The creation of a number of major biological compounds does not take place in the lysosome. Instead, it is an organelle that may degrade and recycle a variety of macromolecules, including proteins, nucleic acids, lipids, and carbohydrates. It is a component of animal cells. Proton pumps that actively transport hydrogen ions into the lysosome maintain the acidic environment necessary for these enzymes to function at their best. Although the lysosome does not participate in the production of new molecules, it is essential for maintaining cellular homeostasis and reducing the buildup of waste products since it breaks down and recycles molecules.

As the temperature increases, the average kinetic energy increases, making the gas particles hit the walls of the container more (therefore increasing pressure). Hopefully this helps! Good luck :)

1) Fossils are the preserved remains of traces of organisms from the past so they are very important evidence for evolution. They show extinct organisms that were very different from any now living, it also shows successions of organisms through time. Fossils tell us when organisms lived, they provide evidence for the progression and evolution of life on the earth over millions of years.

Answer and Explanation: Growth can be classified into two categories in living organisms. It is vegetative and reproductive growth.

Biologically, other than growing in size, any organism will show reproductive growth. Be it a plant, animal, fungus, or any other microorganism, all of them show reproductive growth.

In the biological world, there are four main types of reproductive growth. They are vegetative reproduction, asexual reproduction, sexual reproduction, and parthenogenesis. Like size growth, reproductive growth can also be logarithmic, or exponential.

Hence, reproductive growth is another very important form of growth other than the size of the body. Reproduction ensures the continuity of the generation and maintenance of species. Reproductive growth also helps to bring in genetic variation and ensure survival due to mutation.

The radiation doses can be different depending on a lot of factors, such as geographical location, occupation, medical procedures, and others.

The typical human yearly exposure to radiation on our planet is measured at 3 mSv, enabling us to gauge it against various degrees of radiation exposure.

A person is usually exposed to around 0.01 mSv during a dental X-ray and approximately 0.1 mSv during a chest X-ray. It is crucial to acknowledge that diverse forms of radiation can produce distinct impacts on the human body, and hence, tracking and regulating the extent of exposure is necessary to reduce potential hazards.

Answer:

B. From low concentration to high concentration

Explanation:

I got it right on edge :)

Answer:

B

Explanation:

You can think of it as a very useless sponge and water.

If you have a dry sponge you can consider this an area of low concentration, and the bucket of water as an area of high concentration of water.

It is easy to soak up water with a dry sponge with osmosis when the high concentration easily fills the low concentration sponge.

On the other hand, a soaked sponge will have a great time trying to soak up a bucket of water with an already wet sponge.

This is a crude example of differing high to low or low to high concentration.

Osmosis is limited to water particles, whereas diffusion is basically molecules.

Osmosis is the movement of water along the concentration gradient.

Active transport is the use of energy to move particles against the concentration gradient so it is active, it is attempting to enact homeostasis.

Passive transport is the movement of particles by diffusion without energy so it is just passive, not aggressive.

Diffusion is the movement of particles along the concentration gradient.

As temperatures increase, corals lose their symbiotic algae, which provide most of their energy. This is the best description to the effect of coral bleaching on corals. Thus, the correct option is C.

A coral reef is an underwater ecosystem which is characterized by the reef-building corals. Bleached corals are found in the underwater ecosystem which most likely show reduced growth rates, decreased reproductive capacity, increased susceptibility to diseases, and elevated mortality rates than the normal coral reefs. Changes in the coral community composition can occur when the more susceptible species are killed by bleaching events in the ecosystem.

When the conditions such as the temperature change, corals are expelled out the symbiotic algae which is living in their tissues, it is responsible for their colour. A spike of the temperature to 1 to 2°C in the oceans sustained over several weeks which can lead to bleaching, that turns corals white. If the corals are bleached for prolonged periods of time, they eventually die.

Therefore, the correct option is C.
