Answer:
c
Explanation:
The statement which is not true about enzyme behavior is that all enzymes have an active site where substrates are temporarily bound.
Enzymes are proteins that can act as biological catalysts by increasing the rate of chemical reactions. The molecules upon which enzymes may act are known as substrates, and the enzyme which converts the substrates into different molecules are known as products. Almost all metabolic processes which take place in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life.
Metabolic pathways depend upon the enzymes to catalyze individual steps. The study of enzymes is called as enzymology and the field of pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and thus have unusual 'pseudocatalytic' properties.
Thus, statement which is not true about enzyme behavior is C.

Could someone help : how does the number of offspring that are produced by an individual typically compare with the fecundity of that individual? What factors create this (think of reproductive potential)
Answer:
The number of offspring produced is often related to the amount of parental care. Typically, the higher fecundity, the lower the amount of time parents devote to caring for the offspring.
The number of offspring that are produced by an individual typically varies with the fecundity, as the higher the fecundity, the lower the parental care per offspring, while a lower fecundity leads to more parental care.
What is parental care in the animal kingdom?Parental care refers to the behaviors of parents for the care of their offspring, and in the animal kingdom, parental care can take many forms, ranging from simple behaviors like providing food and shelter to more complex behaviors like teaching and training offspring and parental care is important for the survival and development of offspring, as it can improve an offspring's chances of survival by providing them with resources, protection, and guidance.
Hence, the number of offspring that are produced by an individual typically varies with the fecundity, as the higher the fecundity, the lower the parental care per offspring, while a lower fecundity leads to more parental care.

¿Qué efecto tiene para las cadenas tróficas la tala y deforestación de los organismos productores?
Answer:
tiene un efecto devastador sobre las cadena tróficas de ecosistemas terrestres
Explanation:
En una cadena trófica, los organismos productores, también conocidos como autótrofos, son aquellos capaces de convertir la energía proveniente del Sol (organismos fotosintéticos) o de la oxidaxión de compuestos inorgánicos (organismos quimiosintéticos) en nutrientes a través de la formación de enlaces de carbono que componen moléculas orgánicas tales como, por ejemplo, carbohidratos (es decir, celulosa, azúcar, etc). Por ejemplo, los árboles son organismos productores que usan la fotosíntesis para convertir la energía lumínica solar en energía química la cual es utlilizada por consumidores primarios (hervívoros) de la cadena trófica. Los árboles son organismos productores los cuales juegan un papel clave en ecosistemas terrestres, representando la principal fuente de alimento y nutrientes para diferentes consumidores primarios. Además, estos organismos autótrofos son también fundamentales porque generan oxígeno (O2) y capturan el dióxido de carbono (CO2) de la atmósfera, lo cual es un proceso clave para el sostenimiento de la vida en la tierra.

Where does the carbon dioxide come from
that we exhale during cellular respiration?
Answer:
The carbon we breathe out as carbon dioxide comes from the carbon in the food we eat. The carbohydrates, fat and proteins we consume and digest are eventually converted by a number of different biochemical pathways in the body to glucose (C6H12O6)
Explanation:
Cellular respiration involves the breakdown of complex food materials. During cellular respiration, glucose is broken down to give carbon dioxide and water. That how we get the CO2 that we exhale.
Respiration is one of the characteristics of living things. Living things take in oxygen and give out carbon dioxide. During cellular respiration, oxygen combines with glucose to yield carbon dioxide and water.
This carbon dioxide produced during cellular respiration as a result of the breakdown of glucose is passed out to the exterior during exhalation.

Identify the correct amino acid sequence for the mRNA strand ACG using the codon chart below.
Threonie
Serine
Lysine
Arginine
Answer:
option 4 is your answer
Explanation:
The correct amino acid for the ACG sequence is Threonine (Thr).
During translation, a messenger RNA (mRNA) sequence is read in the ribosomes to synthesize a polypeptide chain (i.e., a protein).
The correct order of triplets of nucleotides or 'codons' in the mRNA determines the order of amino acids in the nascent polypeptide chain.
Each codon determines a specific amino acid. In this case, the codon ACG encodes for the amino acid Threonine.
In conclusion, the correct amino acid for the ACG sequence is Threonine (Thr).

what property of water makes water so helpful in riding the body of wastes?
A) Water is versatile solvent.
B) Water is expands upon freezing
C) Water cohesive forces surface tension upon its surface
D) Water has a high specific heat.
Answer:
A) Water is versatile solvent.
Explanation:
Water is a chemical compound consisting of one atom of oxygen (O) bonded chemically to two atoms of hydrogen (H). It is a unique substance due to its properties. Water is a polar molecule i.e. has both positively and negatively charged ends, hence, making one of its properties of being a UNIVERSAL SOLVENT possible.
Water is said to be a universal solvent because it can dissolve more solid substances than any other liquid. This outstanding property of water is key to its function in getting rid of wastes because these wastes readily dissolve in water and are transported or carried to sites of exit from the body. For example, urea is a waste in humans, which gets dissolved in water to form URINE that is excreted.

If an organism had 20 chromosomes, how many chromosomes would the daughter cell have after mitosis? After meiosis?
Answer:
After mitosis, the daughter cell has 20 chromosomes and after meiosis, the daughter cell has 10 chromosomes.
So the answer is 20 and 10
Answer:
[tex]\boxed {\boxed {\sf Mitosis: 20 \ chromosomes}}[/tex]
[tex]\boxed {\boxed {\sf Meiosis: 10 \ chromosomes}}[/tex]
Explanation:
Mitosis and meiosis are both types of cell divisions, but they are different.
Mitosis
1 cell division that results in 2 daughter cells used for growth, repair, and developmentThe cells are genetically identical with the same number of chromosomes as the parent cell.Meiosis
2 cell divisions resulting in 4 daughter cells for sexual reproduction The cells are genetically different and have half the number of chromosomes as the parent.The organism has 20 chromosomes.
Mitosis: same number of chromosomes=20 Meiosis: half the chromosomes= 20/2= 10After mitosis, the daughter cell has 20 chromosomes. After meiosis, the cell has 10.
