2a. The enzyme called Pheide a Oxygenase (PAO) catalyses the degradation of chlorophyll. Mendel’s I gene (yellow peas) codes for this enzyme. If this gene is mutated, what will happen to the pea colour? 2b. What was discovered when looking at the PAO levels between heterozygous and homozygous plants? 2c. Gibberellin is a plant hormone that promotes the elongation of plant stems. It is produced in a series of reactions requiring an enzyme coded for by a specific gene. If this gene is isolated, and mutated, how will this affect the height of the plant? 2d. Mendel’s R gene (round peas) codes for the enzyme Starch-branching enzyme isoform (SBEI) which forms 1,6 linkages in starch, producing Amylopectin. If 1,4 linkages were produced instead, what type of starch would be formed? This would cause the peas to display recessive traits. How will the peas look and taste?
2a. Yellow peas are dominant (Y). Green peas are recessive (y). Peas that are green in color are immature peas. When the pea ripened, the chlorophyll will broken down in the pathway. The pea will eventually turns to yellow. The enzyme responsible for this process is Pheide a Oxygenase (PAO) .
If the gene is mutated, PAO will not be produced. Pea will remain green because chlorophyll will not be broken down.

When sodium levels drop,_______ is involved in sodium retention in urine, sweat, saliva, and digestive secretions.
Aldosterone is involved in sodium retention in urine. In its primary target tissues, aldosterone encourages vigorous salt transport and potassium excretion.
What is the function of aldosterone?
Aldosterone promotes active sodium excretion in its main target tissues. It controls the body's salt and water balance by increasing sodium and water retention and potassium excretion by the kidneys. Additionally, it only slightly affects how proteins, carbs, and lipids are metabolized.
Aldosterone is essential for sodium storage in the kidney, salivary glands, sweat glands, colon, and other organs. These organs are signaled by aldosterone to increase the quantity of sodium produced in your urine. Your body retains water in your blood due to aldosterone's action on sodium elevation, increasing blood volume.
Hence, when the sodium level drops, aldosterone is involved in sodium retention in urine, sweat, saliva, and digestive secretions.

Describe two ways that each of the following pairs are similar with each other and two ways in which they differ from each otherdesmosomes vs. tight junctions
Both desmosomes and tight junctions are clusters of proteins that act by binding membranes of adjacent cells. However, they have some differences. While desmosomes cross the plasma membrane and thus provide a stronger bond, the tight junction proteins (claudins) remain on the outside of the membrane and bind to the claudins of other cells; therefore, they provide a less strong binding than desmosomes, but function to make the tissue impermeable. The bladder is an organ that possesses many tight junctions.
In conclusion:
Similarities:
1- They bind cell membranes
2- They are composed of proteins
Differences:
1- Desmosomes go through the membrane, tight junctions do not.
2- Desmosomes are a stronger junction that holds the tissues together.
Tight junctions are less strong and their main function is to maintain an impermeable barrier.

Which parenting style is most closely associated with children who are inclined to be withdrawn and tend to do poorly in school?
Question 5 options:
Permissive parents
Inconsistent parents
Authoritarian parents
Authoritative parents
The parenting style most closely associated with children who are inclined to be withdrawn and tend to do poorly in school is Authoritarian parents.
Authoritarian parenting is characterized by strict rules, high demands, and low responsiveness. Parents with an authoritarian style tend to be controlling, demanding obedience and conformity from their children without much room for discussion or negotiation. They often have a strong emphasis on discipline and have a tendency to use punishment as a means of control.
This parenting style can lead to negative outcomes for children, including social and academic difficulties. Children raised in authoritarian households may become withdrawn and lack self-confidence. The strict control and lack of warmth and responsiveness from authoritarian parents can hinder children's autonomy and independence, leading to feelings of anxiety, low self-esteem, and a tendency to withdraw from social interactions.
Furthermore, authoritarian parenting tends to limit children's opportunities for exploration and decision-making, which can negatively impact their academic performance. The rigid and demanding nature of authoritarian parenting may hinder children's motivation to learn, as they may feel pressured and fear making mistakes.
In contrast, authoritative parenting, characterized by a balance of rules and warmth, is associated with more positive outcomes for children, including better social and academic outcomes. Authoritative parents set clear expectations but also provide support, nurturing, and open communication with their children, fostering a sense of autonomy, self-esteem, and a positive attitude towards learning.
Therefore, the parenting style most closely associated with children who are withdrawn and tend to do poorly in school is Authoritarian parents.

a) to kill the specimen
b) to keep the specimen from moving around
c) an explosion would occur
d) to prevent the operator from becoming contaminated
e) the air would interfere with the electrons
Air has to be removed from the canister of the electron microscope because the air would interfere with the electrons (option E).
What is electron microscope?Electron microscope is any of the several forms of microscope that use a beam of electrons, rather than one of light, and thus has a much greater resolving power.
Electron microscopes are very powerful biological tools used to visualise variety of samples. They are used by scientists to view cells, tissues and small organisms in details. However, it should be noted that these living samples cannot be viewed on electron microscopes.
The vacuum inside the electron microscope is one reason why living samples cannot be viewed. The beam of electrons being aimed at the sample would be deflected when they hit air particles if the vacuum is not present.
Therefore, it can be said that the air is one component that must be eliminated to allow a direct passage of electrons.

We have the data of the known areas
The new area is similar to Northeastern SA and Northen SA in terms of the type of prey and the growth rate, as well as rainfall.
And even if the density is greater, the total biomass is similar to Northeastern SA, so the population that the new area can support must be similar to the one in there.
Northeastern SA has an area of 1000 km2, so, according to the next graph, it can sustain at least 29 individuals. This means the new area should be able to support around that same quantity.

give reason for some enzymes have a reversible effect
The reason that some enzymes have a reversible effect is-
The ability of an inhibitor to attach to an enzyme non-covalently and easily dissociate from it is known as reversible inhibition. In a process known as competitive inhibition, the inhibitor, which mimics the substrate, attaches directly to the enzyme's active site and blocks the enzyme's function.
What are enzymes?Proteins called enzymes speed up chemical reactions and serve as biological catalysts. The molecules that enzymes can interact with are referred to as substrates, and the enzyme changes the substrates into new molecules known as products. In order to occur at rates quick enough to support life, almost all metabolic processes in the cell require enzyme catalysis.

the period of planetary formation.
Different types of planets in the solar system illustrate density distribution throughout the period of planetary formation. Mercury, Venus, Earth and Mars are dense whereas Jupiter, Saturn, Uranus and Neptune are less dense.
The Solar System consists of the Sun with eight planets orbiting it. The four inner planets are those closest to the Sun .They are Mercury, Venus, Earth, and Mars. They are smaller and composed of metals and rocks and hence are dense. The four outer planets are Jupiter, Saturn, Uranus, and Neptune. They are larger and mostly made of gases, so the overall density is low A planet's density is related to its composition.
Mercury is the smallest in size. Earth and Venus are almost the same size, whereas Mars is about half their size.
According to the nebular hypothesis, Uranus and Neptune exist in a region where the density of the solar nebula is reduced and longer orbital times is longer . The two are thought to have formed in orbits near Jupiter and Saturn, where more material was available, and to have migrated outward to their current positions over hundreds of millions of years.
