Which processes are involved in sexual reproduction in plants?
Answer:
Sexual reproduction in flowering plants involves the production of male and female gametes, the transfer of the male gametes to the female ovules in a process called pollination. After pollination occurs, fertilization happens and the ovules grow into seeds within a fruit.
Explanation:
What is the evidence that glaciers once existed on all of the southern continents?
A.Grooves in the rocks and sediment deposits.
B.Fossil evidence of cold weather species.
C.Radioactive isotopes in the ice cores
D.Large glacial lakes still exist
Answer:
A.
Explanation:
There is also much climate evidence supporting continental drift, most notable of which is glacial activity. Alfred Wegener investigated this field and found an anomaly in the Permo-Carboniferous ice sheet that was found through glacial till deposits to have once covered all the southern major plates.
All of the plants and animals living in the same area make up a?
1. Population
2. Community
3. Species
4. Habitat
All of the plants and animals living in the same area make up a community. So, the correct option is B.
What is Community?All the plants and animals that coexist in a region are referred to as a community, as are their interactions. It contains all of the various species that exist there and their interactions with one another, such as mutualism, competition, and predation.
A community in ecology is the collective term for all the populations of various species that coexist and communicate within a specific habitat or geographical region. It covers all of the local living things, including plants, animals, fungi, and bacteria, as well as their relationships. All of the plants and animals living in the same area make up a community.
Therefore, the correct option is B.

Which of these is the best definition of "producer" in an ecological sense? А none of these B) organisms that produce stored chemical energy c organisms that convert environmental energy in to stored chemical energy D) plants E) algae and phytoplankton
Answer :
D) Plants
Explanation :
A producer is a plant or organism that produces it own food. Plants go through a process of Photosynthesis Which makes its own food.
Step 1 - All the reactants collect in the Chloroplast
Step 2 - Light energy from the sun drives the reactants to make a chemical reaction.
Step 3 - The products of the chemical reaction including Glucose the plants food and Oxygen, which is released into the air and which living organisms breathe.

Do all plants do photosynthesis ?
Answer:
This is what Bing says
"Using solar energy to turn carbon dioxide and water into sugar and oxygen is what happens during photosynthesis. When you ask which plants use carbon dioxide, you are really asking which plants do photosynthesis. So if all plants do photosynthesis then the answer to your question is yes, all plants use carbon dioxide."
Explanation:
So the answer is yes
unless Bing is wrong

Answer:
DNA does not act directly on other molecules instead lots of enzymes act on DNA and copy its Info
Explanation:
an innovation among the dicynodonts that allowed them to fill brand new niches. an innovation among the dicynodonts that allowed them to fill brand new niches. the availability of previously occupied niches. the availability of previously occupied niches. the extinction of the dinosaurs (except the birds). the extinction of the dinosaurs (except the birds)., the evolution of humans.
Complete question:
If an increase in dicynodont species diversity (in other words, number of species) occurred soon after the Permian extinction, and if it occurred for the same general reason usually given for the increase in mammalian diversity following the Cretaceous extinction, then it should be attributed to
A) an innovation among the dicynodonts that allowed them to fill brand-new niches.
B) the availability of previously occupied niches.
C) the extinction of the dinosaurs (except the birds).
D) their out-competition of many other terrestrial organisms.
Answer:
B) the availability of previously occupied niches.
Explanation:
Some species could survive massive extinctions caused by severe natural catastrophes. Some of them were small animals that could hide in certain places that were useful for their protection during the catastrophe. Those animals, that for instance, could hide underground, were able to avoid extreme temperatures and highly toxic gas concentrations caused by the phenomenon. Catastrophes caused severe damage to the Earth´s surface, causing the extinction of many other animal and vegetal species, causing changes in the morphology of the ground, and in temperature. Animals that could survive found themselves in a whole different place. Many niches were now available to be re-occupied. Survivers could specialize in different feeding strategies, finding new different shelters, and developing new morphological characteristics that lead to a rapid diversification and speciation.

X-rays _____.
are blocked by the ionosphere
are less dangerous than ultraviolet rays
have very long wavelengths
are not emitted by the sun
Answer:
have very long wavelengths
Explanation:
The first X-ray image was captured by Wilhelm Conrad Roentgen (1895), who accidentally discovered these rays while experimenting with vacuum tubes. X-rays are high-energy electromagnetic radiation with very long wavelengths (in the range of 0.01 to 10 nanometers, nm). They are shorter in wavelength than ultraviolet rays and longer than gamma rays. X-rays have energies ranging from 100 electron-volts (eVs) to 100 kiloelectron-volts (keVs). On the other hand, the radio waves are blocked by the planet's ionosphere and, therefore, they cannot reach the Earth.
What process causes a zygote (one cell) to become a blastocyst (hundreds of cells)
Answer:
Fertilization
Answer:
lastocyst formation
The zygote develops by mitosis, and when it has developed into 16 cells becomes known as the morula. Until this stage in development, all cells (blastomeres) are autonomous and not specified to any fate. In many animals, the morula then develops by cavitation to become the blastula.

At a deep sea whale fall, the Atlantic hagfish, the crustaceans, and the sand make up which of the following?
Answer:
I would say part of an ecosystem and community.
Explanation:
An ecosystem is a biological community of interacting organisms and their physical environment .In the bottom of the sea,there are already many animals living here and when the whale fall appears at the bottom of the ocean it becomes apart of the ecosystem as it provides them with food.
This is because when a whale dies, its body often falls to the seafloor. The whale's body then becomes food and shelter for organisms in the deep sea. This is called a whale fall. A deep-sea whale fall might support 200 different species for as long as 10 years! Larger species, such as Atlantic hagfish, are the first to arrive to feed on the whale flesh. Later, smaller species of snails and crustaceans come to eat the remaining flesh. Worms burrow into the sand beneath the whale body, and bacteria feed on the whale bones.
Answer:
Part of an ecosystem
Explanation:
The Atlantic hagfish and the crustaceans are living organisms. The sand is a nonliving part of the environment. An ecosystem is made up of living organisms and the nonliving parts of their environment. So, the Atlantic hagfish, the crustaceans, and the sand make up part of an ecosystem.

What type of rock is Mount Kinabalu made of?
photosynthesis, respiration, volcanic eruption, decomposition
Answer:
-> photosynthesis: the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
-> respiration: a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.
-> volcanic eruption: Volcanic eruptions happen when lava and gas are discharged from a volcanic. Volcanic eruptions often cause temporary food shortages and volcanic ash landslides called Lahar. The most dangerous type of volcanic eruption is referred to as a 'glowing avalanche'.
-> decomposition: Dead organisms are broken down into smaller pieces by the process of decay.
Explanation:
Hope you get your answer correct!
Have a good day :D
Answer:
Photosynthesis: Photosynthesis is the process by which plants convert light energy to starch and chemical energy to manufacture their own food.
Respiration: Respiration is the process by which a living thing breathes in air. humans breathe in oxygen and breath out carbon dioxide, on the other hand plants breathe in carbon dioxide and breathe out oxygen.
Volcanic Eruption: Volcanic eruption is the process when a volcano sends out lava to the outer surface of the earth due to tectonic plate movements.
Decomposition: Decomposition is the process by which dead organic substances or decaying matters are broken down into simpler organic or inorganic matters with the help of natural processes.
