In an experiment, a scientist places human red blood cells in seawater. What changes do you think would be made to the red blood cells due to osmosis? Cite facts about osmosis to support your prediction.

Answers

Answer 1
Osmosis is when water diffuses into (for example, a plastic bag), so I think the red blood cells would have more water in them and probably increase in size (if I’m not right please correct me!)
Answer 2

Osmosis is when water diffuses into (for example, a plastic bag), so I think the red blood cells would have more water in them and probably increase in size.

What is Osmosis?

The net movement of solvent molecules through a semipermeable membrane is known as osmosis. Since the movement is downward and goes from greater to lower concentration, it is comparable to diffusion.

However, in osmosis, the movement must take place through a membrane that is semipermeable or selectively permeable. It cannot be referred to as osmosis without this component.

The main components of a solution are the solute (a material that needs to dissolve) and the solvent (the component that dissolves the solutes). To determine if a solution is isotonic, hypotonic, or hypertonic in comparison to another solution, the constituent concentrations of the two solutions must be compared.

Therefore, Osmosis is when water diffuses into (for example, a plastic bag), so I think the red blood cells would have more water in them and probably increase in size.

4. Stage II in the diagram most correctly represents

A denatured enzyme
An inorganic catalyst
An enzyme-substrate complex
A vitamin

Answers

An enzyme-substrate complex. The enzyme is the purple, and the red is the substrate. The enzyme can build and break apart the substrate.

Stage II in the diagram most correctly represents an enzyme-substrate complex. Thus, the correct option for this question is C.

What are Enzymes?

Enzymes may be defined as biocatalysts that significantly increase the rate of chemical reactions without themselves being consumed or changed in the overall process. Virtually, it is thought that all cellular reactions and processes are mediated by enzymes.

The structure represented by the purple color is the enzyme while the component of the red color is known as the substrate. So, in stage II, both enzyme and substrate significantly fit into one another like lock and key. So, this stage in the diagram most correctly represents an enzyme-substrate complex.

Therefore, the correct option for this question is C.

What happens next after the ribosome reaches the start codon?
A. Peptide bonds between amino acids are broken.
O B. The ribosome detaches from the amino acids.
C. TRNA molecules attach to codons.
D. The ribosome finds the stop codon.

Answers

C. ———//———-////——-///———

Once the ribosome reaches the start codon, the next step in protein synthesis is the binding of a complementary tRNA molecule carrying the appropriate amino acid to the codon, which is option C.

What is translation in proteins?

During translation, the ribosome reads the codons in the mRNA strand, which specify the sequence of amino acids that will be assembled into a protein. The ribosome does this by binding to the mRNA at the start codon (usually AUG), which indicates the beginning of the protein-coding sequence. Once the ribosome is positioned at the start codon, the first tRNA molecule carrying the appropriate amino acid binds to the codon via complementary base pairing between the codon and the anticodon of the tRNA.

Hence, the next step in protein synthesis is the binding of a complementary tRNA molecule carrying the appropriate amino acid to the codon, which is option C.

They have no current use, because they were passed down from a common ancestor, homologous structures are those that are comparable in related organisms, hence option C is correct.

What is homologous structures?

The descendants of these structures may or may not carry out the same purpose. Tetrapods' four limbs are an illustration of homologous features. All four limbs are present in birds, bats, mice, and crocodiles.

Bony fish such as sharks do not. Tetrapods evolved four limbs, and their descendants have carried on this trait.

As a result, the presence of four limbs is a homology. The upper arm of both humans and cats consists of just one bone, which we refer to as the humerus, and two forearm bones, the radius on the more medial side and the ulna on the more lateral side.

Therefore, option C is correct.

Answers

Answer:

Mitosis

Explanation:

The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diploid cells.

After mitosis, the daughter cell has 20 chromosomes and after meiosis, the daughter cell has 10 chromosomes.

Explanation:
Mitosis is part of cell replication. The cells formed during mitosis are called diploid, because they have the same number of chromosomes as the parent cell.
Meiosis is a type of cell division which produces gametes. These gametes are haploid cells because they have half of the number of chromosomes as the parent cell.

> all cells carry a small protein on their surface called antigens

> every cell has a different shaped antigen

     > also meaning if lets say a virus mutates its antigen will change shape

so there are 2 types of antibodies that help fight pathogens together

1) lymphocytes : recognise antigen and make a complementary antibody to fit the antigen this will neutralise the pathogen ( basically seals the whole pathogen with antibody meaning it cannot reproduce or produce toxins if bacteria) and ALSO THEY MAKE THE PATHOGEN BIND TOGETHER so that the phagocyte can kill more pathogen at once

2) phagocytes : do not produce antibodies. and they identify the antigen and ingest and destroy the pathogen 70% of white blood cells are phagocytes
