There has been a rise in the atmospheric carbon dioxide level and global temperature since 2014.
What is Temperature?This is referred to as the degree of hotness or coldness of a substance or body and its SI unit is Kelvin.
Carbon dioxide has been on the rise due to it being formed from the combustion of fossil fuel burning thereby leading to global warming.

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.
Explanation:
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
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.

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.

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

In grammatically correct sentences trace the path of the products of photosynthesis as they exit the leaf.
Answer:
The correct answer is -
O2 - through the stomata
Glucose - through the phloem in the veins
H2O- through stomata
Explanation:
In the process of photosynthesis, plants capture light energy to initiate a chemical reaction that uses CO2 and H2O as reactants and converted them into oxygen and sugar or glucose as products. Thus, oxygen and glucose are the products form in photosynthesis.
These products are carried through various paths to the new location to get utilized. Glucose is carried by the phloem in the veins out to the plant whereas oxygen and water diffuse into the environment through stomata.

Which of these events can lead to an increase in the population size of mice?
a. Some mice emigrate (leave) in search of food
b. Cats, owls, and snakes are added
c. More mice are born than die
d. A large number of mice die because of a forest fire
e. Cheese shortage
This means the birth rate would exceed the death rate, to make a positive growth rate in the population. So overall, the population will go up if more mice are born compared to those that die off.
Choices A, B, D and E all describe factors that would either kill mice or push them out of the habitat. Either way, these answer choices would have a decrease in population rather than increase. So we can eliminate these answer choices.

With a ruler, draw a line that is 20 cm long. Divide the line into five, 4-cm segments. On a scale of each segment representing one billion years, label the following events in the history of Earth:
a. formation of the earth
b. origin of life
c. evolution of photosynthesis
d. evolution of eukaryotes
e. evolution of multi-cellular life

h. evolution of dinosaurs
i. evolution of human beings
Solution:
The first traces of the life that existed on the earth can be traced back to about as old as 4.2 billion years. It indicates that life has evolved around 200 million years ago after the first appearance of the liquid water.
The origin of the life on earth is a natural process and is a series of evolution what we see today. Firstly earth was formed by dust and smoke particles and then different forms of life began to evolved on the earth.
The events of the evolution in the history of the earth is shown on the following number line below :
