Answer: Ovary

Explanation: In flowering plants, the female reproductive structures that produce seeds are contained within the carpels of the flower. A carpal consists of the stigma, style and ovary. The ovary contains ovules (eggs) that become seeds once they are fertilized.

Explain how musicians use wind instruments to play music?

Westkost [7]

A wind instrument is a musical instrument that contains some type of resonator (usually a tube), in which a column of air is set into vibration by the player blowing into (or over) a mouthpiece set at or near the end of the resonator. The pitch of the vibration is determined by the length of the tube and by manual modifications of the effective length of the vibrating column of air. In the case of some wind instruments, sound is produced by blowing through a reed; others require buzzing into a metal mouthpiece.

Drag each label to the correct location.

cluponka [151]

Answer:

The geosphere or geosphere is the internal and solid part of the Earth that is composed of three concentric layers called crust, mantle and nucleus. Without the geosphere, human beings cannot live on the planet, since there is no solid ground. In the Earth's geosphere are rocks, minerals, magma, sand and mountains.

This layer interacts with the other layers of the earth system, including the atmosphere, hydrosphere and biosphere, and is in a state of constant motion; Sedimentary, igneous and metamorphic rocks within the Earth's geosphere undergo continuous recycling.

It is said that the Earth formed about 4.6 billion years ago from the collision of meteoric debris that created the solar system. Due to the constant collisions during its formation, the initial temperature of the planet was extremely high; It was all molten matter.

But during the next phase of Earth's formation there was a cooling, and with it, the differentiation of the Earth's layers. Dense materials sank in the center, forming a core rich in iron and nickel. The lighter magma rose to the surface, forming the thickest layer of the Earth called the mantle.

Eventually, the outermost magma cooled to form the thin layer we call Earth's crust.

3. In a field of sugar beets in Georgia the net primary productivity is 120 grams/m^2/day, and the

konstantin123 [22]

Answer and Explanation:

Available Data:

1 gr beets = 2,000 cal

NPP = GPP – Respiration = 120 grams/m2/day

NPP= Net primary productivity of a system

GPP= Gross productivity of the producers

Respiration loss 25% of NPP

Insolation energy is 800 calories/cm2/day

% Efficiency of Photosynthesis = (NPP/Insolation Energy) X 100

1) Find the gross productivity of the sugar beets.

We need to calculate the GPP, which equals NPP - Respiration rate. The respiration loss is 25% of the NPP. This is:

100% NPP--------------- 120 g/m²/day

25% NPP ----------------X = (25 x 120)/100 = 30 g/m²/day

Now that we know the values of NPP and respiration rate, we can calculate the GPP.

GPP = NPP - Respiration

GPP = 120 (g/m²/day) - 30 (g/m²/day)

GPP = 90 g/m²/day

GPP = 0.009 g/cm²/day

2) Using the NPP, calculate the efficiency of photosynthesis for the sugar beets.

% Efficiency of Photosynthesis = (NPP/Insolation Energy) X 100

We know the NPP, but this value is calculated in g/m²/day, while the Insolation energy is in g/cm²/day. We need to calculate the % Efficiency of Photosynthesis in cm. To do that, we must transform the information.

So if 1 m² = 10,000 cm², then:

10,000cm²----------120 grams/m²/day NPP

1 cm²---------------- (1 x 120) / 10,000 = 0.012 grams/cm²/day NPP

We also know that 1 gr beets = 2,000 cal, and that the Insolation energy is 800 calories/cm²/day

So we need to transform Insolation energy from calories/cm²/day to grams/cm²/day, so:

2,000 calories ----------------- 1 gr beet

800 calories/cm²/day---------X = 0.4 gr beet.

% Efficiency of Photosynthesis = (NPP/Insolation Energy) X 100

% Efficiency of Photosynthesis = (0.012 (gr/cm2/day) /0.4 (gr/cm2/day)) X 100

% Efficiency of Photosynthesis = 3 gr/cm2/day

What makes a group of cells a truly multicellular organism?

Anna71 [15]

Multicellular organisms begin as a single cell. These cells then grow and undergo differentiation, the process by which cells develop specialized forms and functions.In multicellular organisms, cells are often organized into tissues, organs, and organ systems.
