Examples of organelles are the ER, the Golgi Apparatus, and the Mitochondria.
Hope this helps.
A structure within a cell that performs a specific function is an organelle. An organelle is a subcomponent of a cell.
What are cell organelles?Cell organelles are the ultrastructure's present in the cell and they show division of labor.
These organelles perform specific function for the cell and thus constitute the framework of all living organisms.
The basic structure of cell contains a plasma membrane, nucleus and cytoplasm. However, ultra-microscopic structures are embedded in the cell cytoplasm and they are designated as organelles in a cell.
Endoplasmic reticulum, Golgi apparatus, mitochondria, ribosomes, microtubules, lysosomes etc. are the specialized organelles present in cell.
Each of these organelles perform specific function. For instance, mitochondria help in energy production, Golgi helps in protein modification and packaging.
Cell organelles are thus important structural and functional elements of a cell.

If a forest ecosystem is removed through clear-cutting, many species of organisms that lived in that ecosystem disappear. Their loss is due to
Answer:
habitat destruction
Explanation:
A forest ecosystem offers a variety of ecosystem services and functions. Prominent among the services offered include habitats to a variety of fauna, watershed protection, carbon sequestration, etc.
When the trees in a forest are removed by clear-cutting, some of the services and functions specific to the tree layers cease. The various habitats provided are destroyed and the organisms that live in these habitats disappear.
Hence, if a forest ecosystem is removed through clear-cutting, many species of organisms that lived in that ecosystem disappear. Their loss is due to habitat destruction.

What is one way people have negatively affected land resources?
A) Habitat restoration
B) Urbanization
C) Terrace farming
D) Reforestation
Answer:
b
Explanation:
Urbanization is one way people have negatively affected land resources. Therefore, the correct option is B.
What is Urbanization?The process of urbanization occurs when the percentage of a country's population living in urban areas increases. This is a result of rural-urban migration, which occurs when people move from rural to urban areas in search of better job prospects, social services, and living standards. Urbanization has both beneficial and harmful effects on the environment and society.
On the plus side, urbanization can promote economic growth, better infrastructure, and greater access to social services, including healthcare, education, and social assistance. Additionally, it helps reduce stress on rural communities, which may experience issues of resource scarcity, resource overabundance, and environmental degradation.
Therefore, the correct option is B.

Turn to the back of your worksheet to answer the rest of the questions. 1. How are igneous rocks formed? Group of answer choices weathering and erosion into sediments, then deposition and lithification rocks get buried deep in the earth where they melt and then cool rocks are under heat and pressure so they can change rock is split into larger pieces and then dissolves in water where it hardens into rock
Answer and Explanation:
Igneous rocks form most of the earth´s crust. They are the result of the solidification of rocky, molten material, the magma. Rocks are melt in the interior of the earth´s crust or in the mantle, and then, as they are less dense than the other rocks, tend to ascend toward the surface. As they ascend, they get cold and solidify.
There are two kinds of igneous rocks, according to the moment of solidification. Extrusive igneous rocks are the ones formed when the molted material gets to get to the earth´s surface and crystalize there. Intrusive rocks get formed when the magma loses its motility before reaching the surface, ending by crystalizing in the deepness.
The opossum, which is native to North America, and the kangaroo, which is native to Australia, are marsupials.
The fact that both these mammals incubate their immature offspring in a pouch provides evidence that they -
O are descended from a common ancestor
O belong to the same species
O must range great distances to eat
have very similar skeletal structures
Answer:
Belong to the same species
Explanation:
Marsupials carry their young in "pouches", and are therefore related to other marsupials, like the kangaroo, opossum, wombats, and koala to name a few.
The opossum is a native of North America as the kangaroo is a native to Australia and both of them are mammals thus boh belong to the same specie. Thus option B is correct.
What are mammals?A mammal is an animal that is warm-blooded and has hair, vertebrates, and backbone. These creatures share human relations and produce milk for their young ones. The kangaroo is like an opossum that is marsupials carry their young in "pouches".

Use the chart above to determine which substitution mutation has the potential to cause more damage? Highlight your answer. (2pts) a. Substitution of 3rd N-base to go from CAU to CAC b. Substitution of 3rd N-base to go from UGU to UGC c. Substitution of 3rd N-base to go from UCU to UUU 3. Explain WHY: (3pts)_________________________________________
Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of the chart referred to in the question. However, what appears to be the case is that the three nitrogenous bases represent codons (and the missing chart is the codon chart). The mutation that has the potential to cause more damage will be the one that would change the amino acid formed from the codon change.
A. CAU to CAC: The codons CAU and CAC both form the amino acid histidine and thus is not expected to cause a major damage.
B. UGU to UGC: The codons UGU and UGC both form the amino acid cysteine and thus is not expected to cause a major damage.
C. UCU to UUU: Codon UCU forms the amino acid serine while the codon UUU forms the amino acid phenylalanine. Thus, this eventual change in the amino acid formed has the potential to cause a major damage and thus option C is the correct option.
NOTE that a codon is a sequence of three DNA/RNA nucleotides that corresponds to a single amino acid.

A segment of DNA is represented in the illustration.
Answer:
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code
Explanation:
As a sequence of nucleotides it is the information for a specific protein carried on the DNA molecule. The correct option is A.
What is nucleotide sequence?The most fundamental understanding of a gene or genome is its nucleotide sequence.
Without having this information, no understanding of how genes function or how evolution works would be complete. It is the blueprint that carries the instructions for developing an organism.
The four nucleotides that make up DNA are adenine (A), thymine (T), guanine (G), and cytosine (C) (C).
The two DNA strands are connected by base pairs, which are formed when the nucleotides (A with T and G with C) bind to one another.
It is the data for a particular protein contained on the DNA molecule as a sequence of nucleotides.
Thus, the correct option is A.

Donald is trying to get through a door but his friend Goofy is blocking the way using 15 N of force. Donald finally pushes on the door with 20 N and gets through knocking Goofy out of the way. Solve for net force.
Answer:
5 N
Explanation:
Goofy is blocking the way with 15 N force and Donald was only able to knock Goofy off using a 20 N force. The net force would be the difference between the applied force of Donald and that of Goofy.
Hence,
20 N - 15 N = 5 N
The net force is, therefore, 5 N.
