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.

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.

What tissues make up a leaf?
Leaves include two different types of photosynthetic parenchyma cells (palisade and spongy). Like all plant organs, they also contain vascular tissue (not shown). Monocots tend to have parallel veins of vascular tissue in leaves, while dicots tend to have branched or net-like veins of vascular tissue in the leaves.

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.

How can using a dam as a source of freshwater also harm wildlife?
A. Dams help control floodwaters.
B. Dams provide drinking water.
C. Dams displace existing habitats.
Ο Ο
D. Dams provide water recreation.
Answer:
c
Explanation:
because its the only one that would be hurting wild life.
Using a dam as a source of freshwater can harm wildlife by displacing existing habitats. Therefore, option (C) is correct.
What are the negative impacts of dams?Dams often require the creation of reservoirs, which can submerge large areas of land and alter the natural flow of rivers and streams. This can lead to the loss of important habitats for fish, mammals, and other wildlife that rely on rivers and streams for food, shelter, and reproduction.
In addition, changes in water temperature, dissolved oxygen levels, and water flow can negatively impact aquatic ecosystems downstream from the dam.
These impacts can be mitigated through careful planning and management, such as the creation of fish ladders and other structures to help fish navigate past the dam, and the release of water at appropriate times to mimic natural flow patterns.

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.

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.

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.
