Which set of features below best describes the radiolaria?
a. phytoplankton; silica 'hard parts'
b. zooplankton; silica 'hard parts'
c. zooplankton; calcite 'hard parts'
d. phytoplankton; cellulose 'hard parts'

Answers

Answer 1

Answer:

The correct option is b

Explanation:

Radiolaria (or radiozoa) are protozoa that produce mineral skeleton often made up of silica. They exist as zooplankton in ocean bodies. Zooplanktons are heterotropic planktons that live in open water bodies; they feed on bacteria and algae and are fed on by fish and insects.

The skeletal remains of Radiolaria make up a large part of the ocean floor and are referred to as siliceous ooze.

From the above explanation, we can deduce that the correct option is b

How does an area's weather differ from the area's climate?

Answers

Weather is the area's day-to-day conditions and climate is the area's average conditions. a natural phenomenon that maintains Earth's temperature range.

Weather refers to the short-term atmospheric conditions, such as temperature, precipitation, humidity, wind speed, and cloud cover, that occur in a specific area over a short period of time, typically days or weeks.

Climate, on the other hand, refers to the long-term average weather patterns observed in a particular region over a period of decades to centuries.

Weather is the day-to-day variation in atmospheric conditions, including temperature, humidity, precipitation, wind speed, and cloud cover. It describes the current state of the atmosphere at a specific location and can change rapidly. For example, one day may be hot and sunny, while the next day may be cloudy and rainy. Weather conditions are influenced by various factors, such as air pressure systems, temperature gradients, and local geography.

Climate, on the other hand, represents the average weather patterns and conditions observed in a region over a long period of time. It is determined by factors such as latitude, elevation, ocean currents, and prevailing winds. Climate provides a broader perspective and encompasses the typical range of weather conditions experienced in a particular area. It takes into account long-term trends, seasonal variations, and averages of weather parameters.

While weather can change from day to day or even hour to hour, climate reflects the long-term patterns and trends in weather. For example, a region with consistently high temperatures and low rainfall throughout the year would have a hot and arid climate, regardless of occasional variations in daily weather conditions.

In summary, weather describes short-term atmospheric conditions, while climate represents the long-term average weather patterns observed in a specific area.

The production and transmission of hormones in the endocrine system is MOST similar to which scenario?

Answers

Answer:

You type a text message, which your friend shows to a third party, who reacts to it.

Explanation:

Copied from google.

When a message is shown to a friend who shows it to another person.

What is the endocrine system?

A group of organs called glands makes up your endocrine system. These glands, which may be found all over your body, produce and emit hormones.

Hormones are substances that communicate with your organs, skin, muscles, and other tissues through your blood to coordinate various bodily activities. These messages instruct your body on what to do and when.

The level of hormones in your blood is regularly monitored by your endocrine system. In order to transmit the message, hormones send their messages by locking them into the cells they intend to reach.

When your hormone levels increase, the pituitary gland signals other glands to stop manufacturing and releasing hormones. The pituitary gland has the ability to tell other glands to manufacture and release additional hormones when levels fall below a specific threshold. Homeostasis is a mechanism that functions similarly to your home's thermostat. Almost every process in your body is impacted by hormones.

Therefore, it is like the scenario where a message is shown to a friend who shows it to another person.

volteretas en la misma dirección. ¿Cuántos metros recorrerá en total
desde la orilla hasta el tesoro? * cuál es la repuesta ​

Answers

Answer:

El pirata recorrerá 455 metros

Explanation:

3,7 hectómetros (hm) = 370 metros (m)

8,5 decámetros (dam) = 85 metros (m)

>> Distancia en metros = 370 m + 85 m  = 455 metros

El hectómetro (hm) es una unidad de longitud que equivale a 100 metros, donde el prefijo hecto indica la equivalencia a 100 metros. Por su parte, el decámetro (dam) equivale a 10 metros, donde el prefijo deca indica la equivalencia a 10 metros.

3. Phosphorus represents only 1% of human body weight. However, it is a building
block of very important macromolecules. Describe some of the cellular functions
that would not be possible without phosphorus.

Answers

Answer:

It would be impossible to store and transfer genetic information

It would be impossible to carry out majority of cellular activities due to lack of usable energy.

Explanation:

Phosphorus, as stated in the question, represents a very low amount in our body system, however, its role in living systems cannot be underestimated. Phosphorus is a vital component of major biomolecules in our system.

- It is the building block of the NUCLEOTIDES that make up nucleic acids. Nucleic acids (DNA and RNA) store genetic information and help transfer it to offsprings. However, without one of the elemental components (phosphorus) that make up its structure, it will not be produced. Hence, the storage and transfer of genetic information will be impossible.

- Phosphorus also makes up the structure of the ADENOSINE TRIPHOSPHATE (ATP) molecule. ATP provides the cell with all the energy used in carrying out cellular functions. However, the absence of phosphorus needed for the synthesis of ATP, ATP will not be produced and ultimately no energy.

Evan finds a rock. He scrapes it with his fingernail and leaves a scratch. His rock must be:
O a metamorphic rock
harder than feldspar
softer than diamond
made of more than one mineral
HELLP

Answers

The correct answer is C. Softer than diamond

Explanation:

Evan observation is related to the rock's hardness, which is usually measured on a scale from 1 to 10, in which 10 represents the hardest rock (diamond). In the case of the rock Evan found, the fact the rock can be scratched just using a fingernail shows the hardness of this rock is 2.5 or below because only minerals with this hardness can be scratched using the fingernail, while a higher hardness requires more complex tools.

Moreover, in this level of hardness, there are minerals such as gypsum or talc and these are softer than others such as feldspar with a hardness of 6 or diamond with a hardness of 10. In this context, it is safe to conclude this rock is softer than diamond. Also, hardness is not enough to determine if a rock contains two or more minerals or if it is metamorphic.

What will happen to an ecosystem that is experiencing a prolonged drought?

Answers

If an ecosystem was experiencing a prolonged drought, there would be a big decrease in the population. All living creatures require water, even the ones well adapted to little water. There probably would be as many planets, for the ones surviving would be ones managing to get water, or ones that can survive off little water. Now on the other hand the animals then wouldn't be getting enough food or water, so then again ones who would manage to survive would be ones adapted to little water and food or are excellent hunters.

  You can also expect some animals to leave the ecosystem look for a better source of water and food.

hope this helps to some degree

The diversity, as well as the number of individuals among different species, may decrease gradually due to the scarcity of water.

What is an Ecosystem?

An ecosystem may be defined as the place or an area where organisms of different species live together and interact with one another for the purpose of food, shelter, and space.

Every living organism on the earth's surface requires water in order to fulfill its requirement for cellular and metabolic activities.

But if the ecosystem experiences a prolonged drought, the physiology of all living organisms is disturbed due to which they leave the ecosystem, hence the number of species gradually lowers.

Therefore, it is well described above.
