Answer:
Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism
Explanation:
An intracellular enzymes can be referred to as endocyto enzymes. These are intracellular proteins that accomplish their function within the same cell that synthesized them. They can be either free in the cytosol or associated with an organelle -inside the organelle or fixated to it-.
--------------------------------------------
Enzymes are catalytic intracellular molecules or polypeptides that accelerate different natural chemical reactions. They have specific binding sites to substrate molecules and turn them into product molecules.
Enzymes are in charge of catalyzing cell metabolism. Since they are proteins, they share many properties with all polypeptides. One of these is that they have a limited temperature level at which they denaturalize.
According to the place where they accomplish their function, enzymes can be called
Plasm-specific enzymes ⇒ Their action field is the plasma ⇒ These are exportation proteins.Secreted or Exocyto enzymes ⇒ Their action field are tissues placed far away from where they were produced and released (for instance, the pancreas secretes and releases enzymes that accomplish their function in the duodene) ⇒ These are exportation proteins.Intracellular or Endocyto enzymes ⇒ All enzymes that accomplish their function within the same cell that synthesizes them ⇒ These are intracellular proteins.Within the cell, enzymes can be free in the cytosol, or fixated to an organelle.
Uniloculated enzymes ⇒ 100% cytosolic enzymes.Biloculated enzymes ⇒ They spend part of the time in the cytosol and part in organelles.--------------------------------------------------------

that is involved in helping plants with seed dispersal.
2. What is the advantage for a plant to produce fruit that are delicious to
animals?
Answer:
1.abiotic- air and biotic-birds
2.producing delicious and good fruits for animals protect and help them to spread. delicious food attract animals like birds and other animals who are feed on them. when they eat the fruits and the seeds pass by unharmed. these way the seed dispersal occur of a plants.
Seed dispersal is a movement transport and spread of the seeds away from the parent plants. As plants have very limited mobility and transportation also includes some of the abiotic factors.
Winds, waves, gravity, and many more abiotic form of seed seed dispersal have been found. The biotic forms of seed dispersal include man, animals and birds. The more delicious is the plant the more is the chance of seed dispersal and hence is an added advantage to the plants. The seeds remain unharmed and many animals like to feed on them.Learn more about the living (biotic) and non-living (abiotic) means of seed dispersal.

Suggest why it is still useful to keep Linnaeus' specimens.
Answer:
As well as changing the way living things were classified, Linnaeus also changed the way they were named. He introduced a simpler method. ... This is rather like our system of giving people a first name and a surname. Each species has its own unique binomial which is the same throughout the world, thus avoiding confusion.

can somebody do 4 and 5 for me
Answer:
4. According to what is observed in the diagram, the maltose (substrate) binds to the maltase (enzyme) to obtain glucose molecules (product), in a process of hydrolysis of the maltose.
5. Three factors that can affect intestinal maltose activity - slowing it down or stopping it - are temperature, pH and substrate depletion.
Explanation:
4. Enzymes, such as maltase, have the function of making a reaction faster and decreasing the activation energy. Maltase is responsible for breaking down a maltose molecule, a dimer, into two glucose monomers, which is a hydrolysis reaction of the bonds that hold glucose molecules together.
5. There are several factors that can cause the decrease or cessation of the activity of an enzyme. Enzymes are activated when substrate is available and work best under ideal temperature and pH conditions. When there are alterations of these factors, the enzyme will reduce or stop the reaction in which it intervenes.
pH: when the pH increases or decreases it produces a decrease in the speed of reaction that catalyzes an enzyme. Very high or low pH levels can denature the enzyme and make the expected reaction not occur. Temperature: like pH, changes in temperature can slow or stop maltase activity. Substrate availability: It is a fact that when the specific substrate of an enzyme becomes depleted, the rate of reaction slows down, stopping when no substrate is available.Which statements best describe shared characteristics?

Describe the role of a nebula in the life cycle of a star. Please use your own words
Answer:Stars are formed in clouds of gas and dust, known as nebulae. Nuclear reactions at the centre (or core) of stars provides enough energy to make them shine brightly for many years. The exact lifetime of a star depends very much on its size.
A star can be defined as a giant celestial (astronomical) object that is made up of a luminous sphere of plasma bounded together by its own gravitational force.
Generally, a star consists of two (2) main interstellar hot gas and these are:
I. Hydrogen (H).
II. Helium (He).
Some of the examples of a star are;
Sun (the closest to planet Earth). Antares. Canopus. Vega. Betelgeus.
A nebula simply refers to a low-density cloud of interstellar hot gas (hydrogen and helium) and dust.
Basically, a nebula is needed for the creation or formation of a star.
Hence, the role of a nebula in the life cycle of a star include the following:
Stage 1: The temperature increases in the center of a nebula, thereby, causing the small nuclei of atoms to fuse.
Stage 2: The nebula gets hotter and brighter as the nuclear fusion sets off a chain reaction while providing enough energy to turn the nebula into a star.

In facilitated diffusion, do molecules move down their concentration gradient? Explain.
Answer:
Molecules move up the concentration gradient in facilitated diffusion, which requires ATP to be used as molecules naturally move from high to low concentration
Explanation:
: )
Molecules move down their concentration gradient in facilitated diffusion through channels of proteins.
For most molecules, movement through the membrane, with a significant rate, is only possible by the presence of transporter proteins (integral membrane proteins, which recognize substances with a high specificity, accelerating their translocation) or channels of proteins.
Transport proteins allow the facilitated diffusion of molecules, moving them along the free energy gradient (concentration gradient, charge gradient, or both), in the direction of thermodynamic equilibrium.
When a carrier protein binds to a solute, the protein changes shape in such a way that it carries the solute to the other side of the membrane.
Facilitated diffusion is similar to simple diffusion, since the molecules move from a region of higher to a lower concentration of solutes.
For example, by facilitated diffusion, chlorine ions move down their concentration gradient into the cell through chlorine channels.
Therefore, we can conclude that many molecules are assisted by transporter proteins for their diffusion through the plasma membrane, a process known as facilitated diffusion, where the molecules descend through their concentration gradient.

if a nutrient were in short supply in an ecosystem, how might it effect an organism
Answer:
Its leads to a deficiency
Explanation:
If a nutrient is in short supply in an ecosystem, it will lead to a deficiency of such nutrient in organisms that are in need of the nutrient.
Such a deficiency can lead to diseases in the ecosystem. If organisms that requires the nutrient cannot find an alternative, it will seriously affect their well being. Such deficiency often lead to very dire consequences for the balance of the ecosystem at large.During a discussion of body systems..which one is true?

Answer:
The correct answer is D.
Explanation:
Reading frame is a sequence of codons determined by nucleotides that are read in groups of three from a specific translation start codon, that is, it is a linear sequence of codons or triplets in a nucleic acid. It is one of three possible reading alternatives of a nucleotide sequence of a series of triplets, this means that, in a double-stranded DNA molecule, there are 6 possible directions in which reading frames can be opened; three in the forward direction and three in reverse.

Which mutation below would result in the greatest amount of change in the proteins that code for a particular trait?
(Please help I will reward)
A. inserting three nucleotides
B. deleting three nucleotides
C. deleting one codon
D. deleting two nucleotides
Answer:
Mutations are errors in codons caused by changes in nucleotide bases. Some mutations may not have much effect. For example, if the codon GAA becomes the codon GAG, because the genetic code is degenerate, the codon will still code for the amino acid glutamate. Such ineffectual mutations are called silent mutations. Some mutations, however, can have a huge affect on coding for amino acids, which can in turn affect what proteins are produced, which can have a profound effect on cellular and organismal function.
