Explanation:
specific defence systemwhite blood cells can do 3 things = they engulf the microbe, produce antitoxins, produce antibodies to neutralise microbe
> 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
fighting diseasesphagocytosis = process of phagocytes destroying pathogenantitoxins producedantibodies producedmacrophages = specialised cell involved in destruction of pathogennon specific defence systemskin

Which of the following statements concerning diffusion and active transport is correct?
Time R
Attempt
11 Min
Active transport requires cell energy while diffusion does not
Both diffusion and active transport require cell energy
Diffusion requires cell energy while active transport does not
The correct statement concerning diffusion and active transport is - Active transport requires cell energy while diffusion does not.
Active transport is the transport of substances or molecules against the concentration gradient in the cell through the membrane.
As it moves against the concentration gradient it requires energy to perform such movement.This process gets energy from the powerhouse of the cellIt is a unidirectional movementit is a selective process.Diffusion is the process where the movement of the solvent takes place according to the concentration gradient. It does not require energy and is a non-selective process.
Thus, the correct answer is - Active transport requires cell energy while diffusion does not.

22.what products of photosynthesis and reactants for respiration belong in the box to complete the cycle?
A -hormones
B -chlorophyll a and chlorophyll b
C -ATP AND ADP
D -glucose and oxygen
Answer:
Glucose and Oxygen hope that helps.
Explanation:
The box in this question is likely referring to the carbon cycle, which is a cycle of biochemical reactions that involve the transfer of carbon between different forms in the environment. The products of photosynthesis and reactants for respiration that belong in the box to complete the cycle are glucose and oxygen.
What is photosynthesis ?Photosynthesis is the process by which plants use energy from the sun to convert carbon dioxide and water into glucose and oxygen. This glucose is then used by the plant for energy, and the oxygen is released into the atmosphere.
During respiration, the glucose is broken down in the presence of oxygen to release energy, which is then used by the plant for its various functions. The end products of respiration are carbon dioxide and water. Chlorophyll a and chlorophyll b are both types of pigments found in plants that are essential for photosynthesis.
They absorb energy from the sun and help convert carbon dioxide and water into glucose and oxygen. Hormones, on the other hand, are molecules that are produced by the plant to regulate its growth and development.
They are not directly involved in the carbon cycle. Finally, ATP and ADP are molecules that are involved in the transfer of energy within a cell. They are not directly involved in the carbon cycle, but they are essential for respiration as they help to break down glucose and release energy.
In summary, the products of photosynthesis and reactants for respiration that belong in the box to complete the cycle are glucose and oxygen.

The population change equation is Population Change = (Natality - Mortality) + (Immigration - Emigration). Which equation would create stable population?(1 point)
natality + immigration = mortality + emigration
natality + immigration = mortality - emigration
natality + mortality = immigration + emigration
natality - immigration = mortality + emigration
Question: "The population change equation is Population Change = (Natality - Mortality) + (Immigration - Emigration). Which equation would create stable population?"
Answer: "The equation that would best create a stable population would be natality - mortality = immigration - emigration. Hope this helps!"
Population Change = (Natality - Mortality) + (Immigration - Emigration), with the best equation being "natality + immigration = mortality + emigration," with natality being the birth rate and mortality being the death rate (first equation).
What is the significance of the population change?Population change is significant as it explains the growth of the population and shows the pattern of the growth and the stability of the population. It represents a population that is in a state of balance and this balance is only achieved in the population when the number of people being born (natality) is equal to the number of people dying (mortality) and the number of people entering the population (immigration) is equal to the number of people leaving the population (emigration).
Hence, population Change = (Natality - Mortality) + (Immigration - Emigration), with the best equation being "natality + immigration = mortality + emigration," with natality being the birth rate and mortality being the death rate (first equation).

B. They are the most important sets of
bones.
C. They have no current use.
D. These animals do not share a common
ancestor.
Answer: its A
Explanation:
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.

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.
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.

4. Stage II in the diagram most correctly represents
A denatured enzyme
An inorganic catalyst
An enzyme-substrate complex
A vitamin
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.
