Which section highlights metalloids
in the illustration of the
Periodic Table?
- a
- b
- с
Section C highlights metalloids in the periodic table. Therefore, option C is correct.
What are metalloids?Metalloids, also known as semi-metals, are a group of elements that have properties that are intermediate between those of metals and nonmetals. The metalloids are located on the periodic table along a diagonal line between the metals and nonmetals and include the elements boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), and polonium (Po).
Metalloids have a combination of metallic and nonmetallic properties and can exhibit characteristics of both depending on the conditions. Metalloids are also important in biological systems, where they play essential roles in processes such as protein folding and enzyme activity.
Thus, section C highlights metalloids in the periodic table. Therefore, option C is correct.

A recent study has shown an increase in the number of predators in an ecosystem. An increase in the land space available is not a possible cause for the growth. Thus option A is correct.
What is ecosystem ?
An ecosystem is defined as the structural and functional unit of ecology where the living organisms interact with each other and its environment. The term “Ecosystem” was first coined by A.G.Tansley.
The structure of an ecosystem is characterized by both biotic and abiotic components includes energy in our environment, climatic conditions prevailing in that particular environment.
The structure of an ecosystem can be split into two main components, such as Biotic Components and Abiotic Components which are interrelated in an ecosystem.
The functions of the ecosystem include regulation of the essential ecological processes supports life systems and renders stability, responsible for the cycling of nutrients.

Answer:
all of the above can lead to increase in nitrogen
Fertilizer in waterways can lead to an increase in nitrogen, phosphorus, and algae. Therefore, the correct option is D.
What are fertilizers?Fertilizers are substances that are added to soil or plants to provide essential nutrients that promote plant growth and increase crop yields.
Fertilizers contain high levels of nitrogen and phosphorus, which are essential nutrients for plant growth. However, when fertilizers are applied in excess or washed into waterways by rain or irrigation, they can lead to eutrophication, a process in which excessive nutrients cause an overgrowth of algae in the water.
This overgrowth can deplete oxygen levels, harm fish and other aquatic life, and create harmful algal blooms that can produce toxins that are harmful to humans and animals.Therefore, the correct option is D.

What is a Philadelphia chromosome?
Answer:
A piece of chromosome 9 and a piece of chromosome 22 break off and trade places.
Explanation:
The BCR-ABL gene is formed on chromosome 22 where the piece of chromosome 9 attaches. The changed chromosome 22 is called the Philadelphia chromosome.
Answer:
"Philadelphia chromosome. A piece of chromosome 9 and a piece of chromosome 22 break off and trade places. The BCR-ABL gene is formed on chromosome 22 where the piece of chromosome 9 attaches. The changed chromosome 22 is called the Philadelphia chromosome."
"The Philadelphia chromosome forms when chromosome 9 and chromosome 22 break and exchange portions. This creates an abnormally small chromosome 22 and a new combination of instructions for your cells that can lead to the development of chronic myelogenous leukemia."
"People aren't born with a Philadelphia chromosome. It happens because of a mistake our bodies can make later in life. The mistake is that a piece of chromosome 9 sticks to a piece of chromosome 22. This mistake leads to a very serious blood cancer called "chronic myeloid leukemia," or CML."
"The Philadelphia chromosome is seen in more than 90% of patients with CML but also in 5% or less of children with ALL (20% of adult ALL) and in 2% or less of children with AML. Different isoforms of the fusion gene may be present in ALL. ALL in a child with the Philadelphia chromosome has a much poorer prognosis."
"Currently, the standard of care in the frontline setting for fit patients is TKI in combination with chemotherapy. Age-adjusted chemotherapy or corticosteroids alone have been used with TKIs in elderly patients with comorbidities with modest long-term benefit."

what accounts for the significant increase in oxygen in earth's atmosphere 2 to 2.5 billion years ago?
Given what we know, we can confirm that the significant increase in oxygen in the Earth's atmosphere 2 to 2.5 billion years ago is due to cyanobacteria.
What are cyanobacteria?These are tiny bacterial organisms. They were amongst the first organisms to use photosynthesis to sustain life. The sudden boom of cyanobacteria accounts for the rapid increase in oxygen given that they will use carbon dioxide to produce sugar through photosynthesis, expelling oxygen in the process.
Therefore, we can confirm that the significant increase in oxygen in the Earth's atmosphere 2 to 2.5 billion years ago is due to cyanobacteria.

In a Punnett square, parent traits are written as a letter which represent: Question 5 options: alleles genes chromosomes flowers.
A Punnett square is a diagrammatical representation in the form of a square that depicts the genotype and the phenotype. The traits written as a letter represent the alleles.
What are alleles?Alleles are the variant of the gene on the chromosome of the genetic material. Allele codes for the specific character of the organism that can be eye colour, hair colour, height, blood group etc.
The alleles on the genes can be recessive or dominant based on their expression in the organism. The dominant allele gets expressed while the recessive gets masked in the presence of the dominant.
The dominant alleles are represented by the capital and the recessive allele by the small letters of the alphabets. The alleles can also be present in purebred or heterozygotic conditions.
