Enzymes can be regulated in a multitude of ways. One such way is by covalent modification, in which functional groups are attached to or removed from the enzyme. One such functional group that can be added to an enzyme is a phosphate group. Depending on the enzyme, addition of a phosphate group may increase or decrease that enzyme's activity. Which of the following is the general name of an enzyme that functions to add phosphate groups to its substrate?
a. Oxidoreductases
b. Ligases
c. Hydrolases
d. Isomerases
e. Transferases
Answer:
Option E
Explanation:
Transferase enzyme are able to transfer a molecule or atom from one compound to the other.
For example – In the process of phosphorolysis, add phosphate to the substrate group .
X-Y + Z = X + Z-Y
Here Z in the phosphate group
Hence, option E is correct

what is a natural resources ??
Answer:
A natural resource is something found naturally that can be used by humanity to accomplish tasks. For example, wood is a natural resource as its found in nature and can be used by humanity for building and making fire for food and heat.
Explanation:
1. Explain how the atomic number and mass number of an atom can be used to determine the number of
electrons and of neutrons respectively.
Because the total of neutron and proton/electron is the atomic mass. So if you wanna find proton/electron and you know the neutron, just minus the atomic number with the neutrom and you will get the proton
Here if you need the formula
Atomic number = Total neutron + Total proton or electron

How “Competition in an ecosystem” is playing a role in life?
Answer:
Competition is an interaction between organisms or species in which both the organisms or species are harmed. Limited supply of at least one resource (such as food, water, and territory) used by both can be a factor.

During what phase of meiosis does both nuclei dissolve, spindle forms?
Answer:
Prophase I
Events of Prophase I (save for synapsis and crossing over) are similar to those in Prophase of mitosis: chromatin condenses into chromosomes, the nucleolus dissolves, nuclear membrane is disassembled, and the spindle apparatus forms. Major events in Prophase I.

When basaltic lava flows in channels or lava tubes it can move up to 30 km/hr (19 mi/hr). How would this type of flow affect the time it took the lava to reach the town?
Answer:
The time will be "2 hours".
Explanation:
Around 10 km/hr, lava eruptions were travelling. The vents was just 15 km (9.3 mi) away Kalapana city as well as 20 km (12.6 mi) from Pahoa city.
So, we therefore need add the method, which would be: to taking out another time that civil defense officials just had to assess a city.
⇒
Thus, to measure the time spent throughout the community of Kalapana,

A new human species was found on a distant planet, whose genetic inheritance and process of reproduction is identical to that of humans on earth, however, their phenotypes are much different. You are tracking two phenotypes in this new species: eye shape and tail size. The single gene that controls eye shape (gene E) is unlinked from the single gene that controls tail size (gene T). Square eyes is the dominant eye shape and round eyes is the recessive eye shape. Long tail is the dominant tail size and short tail is the recessive tail size.
Required:
An individual of this new species is heterozygous for gene E and heterozygous for gene T. What is their genotype and phenotype?
Answer:
The individual has the genotype Ee (for the eyes) and Tt (for the tail) and has square eyes and a long tail.
Explanation:
If an individual is heterozygous, it means that he has a dominant allele and a recessive allele for each genotype. In this case, if the individual is heterozygous for the E gene, he has the genotype formed with the "Ee" alleles. If the same individual is heterozygous for the T gene, it has the genotype formed by the "Tt" alleles.
Individuals with heterozygosis will present phenotypes related to the dominant allele, since the recessive allele is only expressed in hom0zygosis. In this case, the individual will have the phenotype square eyes and long tail.

What is the purpose of xylem?
Answer:
xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as treachery elements. The vascular system is comprised of two main types of tissue: the xylem and the phloem. The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. The phloem carries food downward from the leaves to the roots.

1): Lily is dressing up as a chicken for Halloween this year and is flapping her arms like a bird as she walks from house to house. As Lily flaps her arms down to her sides, what type of movement is occurring?
2): Katie loves pretending that she’s a human cannonball. As she jumps off the diving board, she assumes the proper position before she pounds into the water: head and thighs tucked against her chest; back rounded; arms pressed against her sides while her forearms, crossed in front of her shins, hold her legs tightly folded against her chest. What movement term would best describe the positioning of Katie’s vertebral column, head, thighs, lower legs and lower arms? HINT: She is about as far from the anatomical position as she can get.
Answer:
1. abduction & abduction
2. flexed
A cell has two pairs of submetacentric chromosomes, which we will call chromosomes Ia, Ib, IIa, and IIb (chromosomes Ia and Ib are homologs, and chromosomes IIa and IIb are homologs). Allele M is located on the long arm of chromosome Ia, and allele m is located at the same position on chromosome Ib. Allele P is located on the short arm of chromosome Ia, and allele p is located at the same position on chromosome Ib. Allele R is located on chromosome IIa and allele r is located at the same position on chromosome Ib. Allele G is located on the long arm (q arm) of chromosome Ia, and allele g is located at the same position on chromosome Ib. Allele N is located on the q arm of chromosome IIa and allele n is located at the same position of chromosome IIb.
Required:
a. Draw these chromosomes, identifying genes R, r, G, g, N, and n as they might appear in metaphase I of meiosis. Assume there is no crossing over.
b. Taking independent assortment and the subsequent random separation of chromosomes in anaphase I, draw the chromosomes, with genes identified, present in all possible gametes that could result once this cell completes meiosis. As above, assume there is no crossing over. Explain in your own words what is meant by independent assortment.

During metaphase I, homologous pairs together migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. This random order in the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get the same genetic charge.
B). Taking independent assortment and the subsequent random separation of chromosomes in anaphase I, draw the chromosomes, with genes identified, present in all possible gametes that could result once this cell completes meiosis. As above, assume there is no crossing over. Explain in your own words what is meant by independent assortment.
Independent assortment occurs when the alleles of two or more different genes distribute in the gametes independently from each other. In other words, a gamete receives an allele from a gene that does not depend on nor influence the allele of another gene in the same gamete. This can only be applied to independent genes. An organism gets only one of the members of the chromatids pair of each parent.
During gamete formation in meiosis, the pairs of homologous chromosomes separate after crossing over, and then chromatids sisters also separate, resulting in the formation of four gametes. Each gamete has different information from the combination of homologous chromosomes belonging to the father and to the mother.
There are four possible combinations, considering that there is no crossing over.
Gamete 1: GNRGamete 2: GnrGamete 3: gNRGamete 4: gnr
