Answer:
The pollen contains the sperm cell.
Explanation:
When the pollen grain lands on the stigma and begins to grow a tube, the pollen tube grows down the style to the ovary. Each pollen grain contains a male reproductive cell known as the sperm cell. The sperm cell will go down the tube and unite with an egg cell in the ovary. When the egg cell and the sperm cell unite, fertilization occurs. This newly fertilized egg will make many new cells and will grow into a tiny plant embryo. The embryo is located in the ovule. The ovule is located inside the ovary. The ovule grows into a seed. The plant embryo usually remains in the seed until it is planted in the soil. The stigma, style, ovule, and ovary all make up the female part of the flower called the pistil.

Which of the following choices is the best example of how the cell membrane and mitochondria might work together to make energy in a particular cell?
A. In animal cells, the mitochondria allows materials in and out of the cell, while the cell membrane uses nutrients to make energy (ATP) for the cell.
B. In a plant cell, the mitochondria allows materials in and out of the cell, while the cell wall makes food for the cell by photosynthesis.
C. In a plant cell, the cell wall allows materials in and out of the cell, while the mitochondria makes food for the cell by photosynthesis.
D. In animal cells, the cell membrane allows materials in and out of the cell, while the mitochondria uses nutrients to make energy (ATP) for the cell.
In animal cells, the cell membrane allows material in and out of the cell while the mitochondria use nutrients to make energy (ATP) for the cell. So the correct option is D.
What are mitochondria?
The cellular organelles known as mitochondria are responsible for releasing energy from meals. Cellular respiration is the term for this process. Because of this, mitochondria are frequently referred to as the cell's powerhouses. Numerous mitochondria can be seen in muscle cells and other cells with high energy requirements.
A sequence of chemical events takes place in the cytoplasm when breakdown products from food digestion enter the cell. This enables part of the energy trapped in these products to be released and integrated into ATP, the cell's primary source of energy (adenosine triphosphate).
Therefore, in an animal cell, the cell membrane allows material in and out of the cell while the mitochondria use nutrients to make energy (ATP) for the cell. So the correct option is D

Which kind of soil do temperate climate areas usually have?
-Soil containing little to no organic material
-Soil rich in nutrients
-Soil with a layer mostly composed of clay
-Soil consisting primarily of tiny rock particles
Answer:
Soil rich in nutrients
Explanation:
Temperate soils exist under all types of conditions, including within forests, rain forests and in grasslands, but all have several key things in common. Temperate soils have a rich upper level that is high in minerals and nutrients, and in all cases micro-organisms work to break down decaying matter within the soil.

which characteristic describes both the domain bacteria and the domain archaea?
A. Multicellular organisms only
B. Unicellular and multicellular organisms
C. Eukaryotic and prokaryotic cells
D. Prokaryotic cells only
The characteristic that describes both the domain bacteria and the domain archaea is the prokaryote cell only, which is present in Option D as the prokaryotes lack the cell nucleus.
What is the significance of the bacteria and the archaea?Bacteria and archaea are single-celled microorganisms that are found in almost every environment, ranging from the hottest to the coldest, and play a critical role in the Earth's ecosystems, performing functions such as decomposition, nitrogen fixation, etc, and are used in a variety of industrial and scientific applications, including the production of food and beverages and as model organisms in scientific research, helping scientists to understand basic biological processes, etc.
Hence, the characteristic that describes both the domain bacteria and the domain archaea is the prokaryote cell only, which is present in Option D as the prokaryotes lack the cell nucleus.

How does energy flow through organisms
Answer:
Energy "flows" through the ecosystem in the form of carbon-carbon bonds. ... This process releases the energy, which is either used by the organism (to move its muscles, digest food, excrete wastes, think, etc.) or the energy may be lost as heat. The dark arrows represent the movement of this energy

What would be some effects of the Earth having an unbalanced energy budget (with more energy in than out)?
What would be some effects of the Earth having an unbalanced energy budget (with more energy out than in)
Answer:
Remember that about 29 percent of incoming sunlight is reflected right back to space by teeny tiny bright particles in the atmosphere or bright ground surfaces, which leaves about 71 percent to be absorbed by the atmosphere (23 percent) and the land (48 percent). if you wanna add this go ahead...
The atmosphere itself - Energy into the atmosphere is balanced with outgoing energy from atmosphere. Absorbed shortwave radiation by gases in the atmosphere. Condensation /Deposition of water vapor (heat is released into the atmosphere by process).
When the energy budget balances, the temperature on the Earth stays relatively constant, with no overall increase or decrease in average temperatureEarth gets warmerearth gets coolerExplanation:
