Answer:
C
Explanation:
ecosystem is living AND non living things
The best definition of an ecosystem is option C: "A system formed by the interactions of living organisms with the nonliving physical environment."
What is an ecosystem?An ecosystem is a community of living organisms, such as plants, animals, and microorganisms, interacting with each other and their nonliving environment, including the atmosphere, soil, and water.
This interaction creates a functional system that can be characterized by energy flow and nutrient cycling. The other options are not accurate definitions of an ecosystem, as ecosystems involve both living and nonliving components, and the interactions are not limited to a single species.
Ecosystems are not isolated, and they can interact with other ecosystems. For example, rivers and streams can transport nutrients and organisms downstream, connecting different ecosystems such as a forest and a freshwater system. Similarly, the atmosphere can transport pollutants and other materials across vast distances, affecting ecosystems far from their source.
In summary, an ecosystem is a complex, interconnected system where living organisms interact with each other and the non-living components of their environment. Understanding the functions and interactions within ecosystems is critical to developing effective management strategies for conserving biodiversity and maintaining the ecosystem services that humans depend on.

TRUE OR FALSE: Phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc. In fact, any phospholipid may be called a "cellular tourist" because it is able to move about to virtually any part of a cell and can even become a part of a cell in a different region of the body! (EXPLAIN WHY)
Answer:
False, because phospholipids are a type of lipids and the nuclear envelope contains nucleic acids.
Explanation:
Hope this helps.
It is true that phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc.
What is nuclear envelope made of?The nuclear envelope is made up of two concentric lipid bilayer membranes separated by a 20-40 nm intermembranous space.
In many places, the outer membrane is joined to the rough endoplasmic reticulum. The outer membrane of the nuclear envelope, like the rough ER, is dotted with ribosomes.
The nuclear envelope is made up of two membranes: an outer and an inner phospholipid bilayer. The lumen of the rough endoplasmic reticulum is connected to the thin space between the two layers (RER).
Nuclear pores, which are small channels that run across the nuclear envelope, allow substances to enter and exit the nucleus.
Each pore is lined by a group of proteins known as the nuclear pore complex, which regulates which molecules can enter and exit.
Thus, the given statement is true.

what cellular processes happen during mitosis?
Answer:
the eukaryotic cell undergoes many phases to result in two daughter cells.
prophase
prometaphase
metaphase
anaphase
telophase
Answer:
A eukaryotic cell goes through a few (4) phases to split into two identical daughter cells.
Explanation:
Prophase, metaphase, anaphase, and telophase are the 4 phases.
1st phase: nuclear envelope disappears and chromosomes become visble
2nd phase: chromosomes line up at the middle of the cell (metaphase plate I believe it’s called), to get ready to divide.
3rd phase: replicated chromosomes split and move to different ends/poles of the cell.
4th phase: 2 nuclei form, including 2 identical daughter cells.

Explanation:
Following are the functions of T-lymphocytes, here:
to assist other lymphocytesto kill cells infected with a virus or cancerto help in the body's immune responseWhat are T-lymphocytes?
T-lymphocytes, also known as T cells, are a type of white blood cell that plays a key role in the immune system. They are produced in the bone marrow and mature in the thymus gland.
One of the main functions of T-lymphocytes is to assist other lymphocytes, such as B cells, in the immune response. They do this by releasing chemicals that help to activate and coordinate the immune response, and by directly attacking infected cells.
T-lymphocytes also have the ability to kill cells that are infected with a virus or cancerous cells. They do this through a process called cell-mediated immunity, in which they recognize and bind to specific proteins on the surface of infected cells. Once they have bound to the infected cells, they release chemicals that kill the cells, helping to prevent the spread of the infection or cancer.
T-lymphocytes are an important part of the body's immune system and play a vital role in helping to protect the body against infections and disease.

I understand what earth outer layer is made of underneath the water and soil on the surface
Yes
Or
Not yet
Explain
The planet earth being a terrestrial planet is made up of rocks and hard rigid slabs of rocks called plates. These plates float on the flexible (asthenosphere) Mantel.
I understand that earth is a rocks planet and is made up of rocks and these rocks are called plates.
This uppermost layer or the crust of the lithosphere is composed of SIAL that is rocks made from aluminum and silicon, oxygen components. The layer lying below this is made from the semi-fluid matter called as upper mantel that is the asthenosphere which is partly molten and is said as molten rock. Due to the less dynamicity of this layer the above crust floats or drifts.Hence the water and soil in the lithosphere are characteristic of the crustal rocks.

Animal use chlorophyll to produce glucose.
True
False
Animals use chlorophyll to produce glucose. This is a false statement. Hence, the correct answer is second one . Animals are not autotrophs but heterotrophs.
What is photosynthesis?Photosynthesis is a process in which oxygen and glucose are produced from carbon dioxide and water with the help of sunlight in green plants. This reaction is carried out by the green plant because it consists of chloroplasts.
The chloroplast is the organelle that has chlorophyll pigment, and this pigment is responsible for the photosynthesis process. Due to this, plants are called producers. Animals depend upon the plant for food and are called heterotrophs. Animals cannot do photosynthesis.
In different ecosystems, different producers are present, such as in aquatic ecosystems, where algae and seaweeds perform this function. In terrestrial ecosystems, plants perform this photosynthesis. Consumers feed them depending on the producers, and after both the consumer and the producer die, both are decomposed by decomposers.
Hence, animals use chlorophyll to produce glucose; this is the false statement.

Which plays a major role in determining which genes are expressed in a cell?
A. transcription factors
B.nothing, it is random
C.translating into spanish
D.your mother
Answer:
A.
Explanation:
A crucial component of controlling transcription is played by proteins known as transcription factors. These crucial proteins aid in identifying the genes that are active in each of your body's cells. Thus, option A is correct.
What is the role of transcription factors?Proteins called transcription factors control the expression of genes. They affect the transcription process, in which DNA serves as a template to create mRNA, which in turn affects protein synthesis.
Since many transcription factors are either tumor suppressors or oncogenes, cancer is linked to their mutations or abnormal regulation.
It is known that three transcription factor groups play crucial roles in human cancer.
Therefore, transcription factors play a major role in determining which genes are expressed in a cell.
