Based on the video, do you think changes to the environment could still affect living things on Earth today? Explain your answer using information from the video to support your argument.
Answer:
Yes. Unicellular organisms died because of a change in temperature, which is an environmental change. If the environment on Earth changes too much, it will affect living things. If the changes are too drastic, life may not be able to survive.
Explanation:
the transport a very large molecules such as proteins
Answer:
Very large molecules such as proteins are too big to move through the cell membrane which is said to be impermeable to them. The type of transport proteins present in a cell membrane determines which substances the membrane is permeable to. CO2 molecules pass directly through phospholipids. Glucose molecules travel through the proteins.

which organelle could be used to distinguish between a plant cell and an animal cell?
Answer:
Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not.
state the name of structure that is present in bacteria cells and in plant cells but absent in animal cell
Answer:
cell walls
Explanation:
Cell walls
It provides the cell with both structural support and protection, and also acts as a filtering mechanism. Cell walls are absent in animals but are present in most other eukaryotes including algae, fungi and plants and in most prokaryotes (except mollicute bacteria).

thinking about the components in pcr, do you think there are major differences in the process of dna replication between species?
The major difference in the process of DNA replication between species is the linear order of nucleotides, which can be amplified by PCR. This technique enables the amplification of specific DNA fragments.
The Polymerase chain reaction (PCR) is a technique widely used in molecular biology in order to amplify and thus identify small DNA fragments (approx. 1000 pb).
The PCR uses all materials required to carry out DNA replication: a thermostable DNA polymerase, primers (DNA oligonucleotides), deoxyribonucleotides (ddA, ddG, ddC, or ddT), and template DNA.
The template DNA indicates the linear order of nucleotides that will be added to the amplified DNA fragment, which is highly specific and may vary even between individuals of the same species.

Why do cells become specialized in the human body?
Answer:
They can become any type of cell in the body.
Explanation:
They can transport molecules, metabolize nutrients, and reproduce within this one cell. ... Cell differentiation is the process by which cells become specialized in order to perform different functions. Specialized Cells in the Human Body. Multicellular organisms begin as just one single cell—a fertilized egg.

Why kharif crops cannot grow in rabi seasons?
Answer:
We know that kharif crops such as paddy need more water to grow healthy, which requires in rainy season. But in winter season , which does not requires so much, hence kharif crops cannot grow in this season healthy and properly. Therefore kharif crops cannot be grown in rabi season.
Oceans are being threatened daily by human activities which of the following best describes one way oceans are being impacted?
how does a single genome code for so many types of tissues
Answer:
The genome of a cell contains in its DNA sequence the information to make many thousands of different protein and RNA molecules. A cell typically expresses only a fraction of its genes, and the different types of cells in multicellular organisms arise because different sets of genes are expressed.
The genome, which is the second layer, regulates gene access, allowing each cell type to activate its own unique genes while shutting off the majority of the others.
What is genome?The complete set of DNA instructions present in a cell is known as the genome. The human genome is made up of 23 pairs of chromosomes that are found in the cell's nucleus and one tiny chromosome that is found in the mitochondria.
Everything a person needs to grow and operate is encoded in their genome. The DNA sequence in a cell's genome contains the instructions needed to create tens of thousands of different protein and RNA molecules.
Thus, in multicellular organisms, distinct cell types develop because diverse sets of genes are expressed, even though a cell normally expresses just a portion of its genes.

In the diagram of the human digestive system, what organ is labelled 5?
Answer:
The large intestine
Explanation:
The large intestine is a long, tube-like organ connected to both the small intestine and the anus. In an anatomy drawing, it looks almost as if it is wrapped around the small intestine.
As we can see in the drawing, the organ labelled with 5 is wrapped around another organ which is smaller and looks longer. This smaller organ is the small intestine. Since we know that the large intestine wraps around the small intestine, we can infer that the organ is the large intestine.

3.Which statement describes the major role of lipids within a cell?
Answer:
Lipids perform three primary biological functions within the body: they serve as structural components of cell membranes, function as energy storehouses, and function as important signaling molecules. The three main types of lipids are triacylglycerols (also called triglycerides), phospholipids, and sterols.
Explanation:
The statement that describes the major role of lipids within a cell is they are the main structural components of membranes. The correct option is D.
What are lipids?Lipids have three main biological activities in the body: they are essential signaling molecules, structural elements of cell membranes, and energy storage facilities.
Triacylglycerols (commonly known as triglycerides), phospholipids, and sterols are the three primary categories of lipids. Fats are subtypes of lipids that are typically composed of glycerol and fatty acid chains.
One sort of lipid, which includes fats, is a group of molecules that don't mix well with water. Hydrophobic, nonpolar, and primarily composed of hydrocarbon chains, lipids have a tendency to be.
Therefore, the correct option is D. They are the main structural components of membranes.
