Answer:Plants don't eat food; they have to create it for themselves. They do this through a process known as photosynthesis. Photosynthesis uses water, carbon dioxide from the air and energy from the sun or another light source to create glucose or sugar. This glucose provides the energy the plant needs in order to survive

planet earth King Penguins and Fur Seals King Penguins and Fur Seals are both designed for swimming, and thus are very clumsy on land. With that in mind, answer these questions: Why do the penguins come onto land at all
Answer:
For breeding and moult purpose.
Explanation:
The penguins come onto the land for breeding and moult purpose. They will also spend time ashore during non-breeding months of their life cycle. They are only active at night on land. They leave the colony early in the morning before sun-rise, and return to the colony after dark with food with it in order to feed their families. They can't breed in water like fish so they comes to the land for breeding.

Discuss how destructive fishing practices damage coral reefs.
please explain. this is a written answer. only answer if you are 100%
Answer:
Apart from poisoning the fish, this toxic fishing activity kills animals that are essential to the aquatic environment, such as corals, and provide food and shelter for a number of marine species. One square meter of coral reef is lost with every fish captured using this method. Also, overfishing has the potential to deplete main reef habitats and damage coral habitat. In many places, rapid human population growth, increased demand, the use of more advanced fishery technology, and insufficient maintenance and regulation have resulted in the extinction of key coral species and habitat damage.
BTW, I used my own words
Can I have brainliest?
Answer:
When poisoning the fish other animals around in the aquatic envoiroment like for example corals, which porvide food and shelter for many species of underwater creatures. If this is not stopped coral reefs will become extint which is really bad not only for the species which feed and live there but also to the enviorment.

Please summarize to answer, how do cells undergo differentiation to form the numerous types of cells in the body?
Cellular differentiation, or simply cell differentiation, is the process through which a cell undergoes changes in gene expression to become a more specific type of cell. The process of cell differentiation allows multi-cellular organisms to create uniquely functional cell trt42ypes and body plans. The process of cell differentiation is driven by genetics, and their interaction with the environment.
All organisms begin from a single cell. This single cell carries the DNA coding for all the proteins the adult organism will use. However, if this cell expressed all of these proteins at once it would not be functional. This cell must divide repeatedly, and the cells must begin the process of cell differentiation as they divide. The cell lines begin to emerge, and the cells get more and more specific. Eventually, an entire organism is formed with hundreds of different cell types from this process of cell differentiation.
The original mass of cells, which have not undergone differentiation, are known as stem cells. Unlike normal cell division, which creates two identical daughter cells, the division of stem cells is asymmetric cell division. In this case, one of the cells remains identical to the parent stem cell. In the other cell, chemical triggers activate the process of cell differentiation, and the cell will start to express the DNA of a specific cell type. Stem cells which can differentiate into entire organisms are known as embryonic stem cells and are said to be totipotent.
By contrast, the body also has many cells which are only pluripotent. These cells have already undergone some cell differentiation. These stem cells can only divide into a narrow range of cell types. Bone marrow, for instance, contains somatic stem cells which can only become red blood cells. These cells are necessary for the constant replenishment of blood cells, which are mostly inactive besides their oxygen-carrying ability.
Cell Differentiation Examples
In Animals
After the process of fertilization in animals, a single-celled organism called the zygote is formed. The zygote is totipotent, and will eventually become an entire organism. Even the largest animal on Earth, the blue whale, starts as a single cell. The complex tissues and organ systems, which are completely different in their form and function, all come from the zygote. The process of cell differentiation starts early within the organism. By the time the gastrula has formed, the cells have already started expressing various portions of the DNA.
These changes drive the first folding processes within the embryo. As the tissues continue to form, some cells begin releasing hormones, or chemical triggers which signal various cells to react. Hormone signals direct the expression of DNA in various body parts, which drives their cell differentiation further. In humans it only takes a little over a month for a rudimentary heart and circulatory system to form.
As the systems continue to form, many of the stem cells lose their totipotency, themselves undergoing cell differentiation. This allows for faster production of specialized cells, which the growing organism needs to sustain its growth and enter the world with success. Through cell differentiation, tissues as different as brain tissue and muscle are formed from the same single cell.

In his journey to the Galapagos Islands, Charles Darwin was amazed by the variation in the characteristics of plants and animals he encountered. In any habitat, food can be limited and the types of foods available may vary. One year, there was no rain on these islands. Many plants failed to bloom and produced no new seeds. This left mostly large, tough seeds for the finches to eat. Describe one change in beak characteristics that would most likely occur in the finch population after many generations if this change in seed size became permanent.
For a cell to successfully receive a message from a hormone, which of the following must occur?
A: The hormone must attach to the cell's receptor.
B: The hormone must enter the cell.
C: The hormone must produce neurotransmitters.
D: The hormone must be destroyed.
Answer:
B. the hormone must enter the cell
Answer:
A: The hormone must attach to the cell's receptor.
Which of the following can occur around a subduction zone?
Two parallel mountain ranges commonly develop above such a subduction zone – a coastal range consisting of sedimentary strata and hard rock lifted out of the sea (accretionary wedge), and a volcanic range farther inland (volcanic arc). Ancient magma chamber rocks can be exposed if subduction stops and the volcanoes erode away.

What will finding evidence of microbial life in another world teach us about life in general?
Answer:
Explanation:
There are many things it would teach us. First, it would teach us that we are not alone in the universe. Secondly, it will teach us that there is life that can survive in extremely harsh environments. This will also allow us to examine and understand the biological mechanisms that allow these microbes to survive in these environments. This alone can open up hundreds of doors in science, allowing us to develop new technology, theories, fields etc. There is so much that we can learn about life in general from a single living alien microbe.

One of the pieces of evidence for evolution that Charles Darwin collected on his travels aboard the HMS Beagle was the observation of fossils of extinct animals and similar, but noticeably different species. Giant ground sloth fossils were very similar in shape to the bones of sloths that inhabited the regions of South America he was exploring. The main difference was the size, as the ground sloth fossils were significantly larger that the bones of the sloths he captured alive. What was a conclusion that Darwin was able to arrive to based on this piece of evidence
Answer: Darwin was able to arrive at a conclusion that there was no relationship between the fossils of the ground sloth and the bones of the captured sloths that currently reside in South America.
Explanation:
Evolution is defined as the sum total of adaptive changes that have taken place over a very long period of time. It leads to the development of new species from earlier ones. Evolution is an extremely slow process. It is difficult to obtain direct evidence of evolution in action. However, scientist such as Darwin, have gathered a great deal of indirect evidence that supports the theory of evolution. These evidence comes from many sources including:
--> fossils records
--> biochemical similarities
--> molecular records
--> Comparative anatomy and
--> embryology.
FOSSILS RECORDS shows the existence of species that are now in extinct which lived on Earth during different periods of the planet's history. They provide evidence that organisms from the past are not the same as those found today due to adaptive changes that has occurred over a long period of time on the organism in order to survive in its environment.
There was no relationship between the sloths because of the difference in BONE MASS.

In some forests are cleared by burning .This produces carbon dioxide and ash.
(a) Outline the environment effects of am increase in carbon dioxide in the atmosphere as a result of burning forests.
(b) The ash helps crops to grow bcuz it is rich in minerals, such as magnesium ions ,but it is deficient in nitrate ions.
Explain why nitrate ions and and magnesium ions are important for plants.
Answer:
B. The ash helps crops to grow because it is rich in minerals, such as magnesium ions, but it is deficient in nitrate ions.
Explanation:
After the forest is being burned, ash and carbon dioxide increase on the surface of the ground. It is good for the plant to grow because the plant uses carbon dioxide for photosynthesis, and its root absorbs energy from the ground where ash is very good for the plant to grow.
8. The diagram below shows the shift in the spectrum for hydrogen light from several different sources in the universe.
What is the best argument that can be made from this data?
More distant galaxies are moving toward us faster.
More distant galaxies are brighter.
More distant galaxies are not as bright.
More distant galaxies are moving away faster.
Answer:
more distant galaxies are moving away faster.
the shift towards red (Doppler effect like with sound on Earth) is the indication.
Explanation:
what did this have to do with biology ?
and by the way, this is also something I debate severely in scientific communities, because yes, the red shift is there. but "more distant" also means "more in the past", so that the data shows us actually that things in the past moved faster away. not necessarily today ...
Explain how the cell division of cancer cells like these are misregulated. Identify genetic and other changes that might have caused these cells to escape normal cell cycle regulation
Answer:
Due to non-functioning of protein.
Explanation:
The cell division of cancer cells like these are misregulated because they can't be control by the proteins that is responsible for the control cell division. The cancer cells can multiply without any growth control factors, or growth-stimulating protein signals that control its growth. There are some proteins that is responsible for control of cell division but due to mutation that protein of substance stop working and the cancer cell grows uncontrollable.
