Answer:
C
Explanation:
The karyotype shown in the question is characteristic of Down syndrome, also known as Trisomy 21. Therefore option A is correct.
Down syndrome is a genetic disorder caused by the presence of an extra copy of chromosome 21, resulting in a total of 47 chromosomes instead of the typical 46.
The karyotype reveals three copies of chromosome 21, indicated as 47,XY,+21, which is indicative of Down syndrome in a male individual.
People with Down syndrome may experience developmental delays, intellectual disabilities, and characteristic physical features, such as almond-shaped eyes and a flat facial profile.
The presence of an extra chromosome 21 is the defining genetic abnormality in individuals with Down syndrome.
Therefore option A is correct.

Some genes are important enough to be called "molecular switch" or "master" genes. What is the purpose of these genes?
A. They control when other genes are expressed
B. They determine the organization of the genome
C. They regulate cell metabolism
D. They modulate the rate of translation
Answers
Answer:
Genes called "molecular switch" or master genes have the purpose of control when other genes are expressed (option A).
Explanation:
Master gene is so named because it has the function of controlling the behavior of other genes, organizing their functions and regulating when they can be expressed.
The name of molecular switch is synonymous with the master gene, since its activation determines the genetic regulation necessary to establish cell differentiation and even the determination of the sex of some species.
The other options are not correct because:
B. Master genes do not determine the organization of the genome .
C. Regulation of cell metabolism depends of substances as hormones and enzymes.
D. The rate of translation does not depend on the activity of master genes.

Weak hydrogen bonds between the nitrogenous base pairs hold the two strands of DNA together. Why are the strands held together by weak hydrogen bonds instead of covalent bonds
Answers
Answer:
Explanation:
Hydrogen bonding is usually occur wen interaction with hydrogen atoms occur.
Hydrogen bonds joins DNA polymers because an hydrogen atom occur on on one base which is called hydrogen bond donors and another oxygen or nitrogen atoms on the base across from it which is called hydrogen bond acceptors.
Adenine “A” a purine and Thymine “T” a pyrimidine each have a donor and one acceptor, whereas Cytosine “C” a pyrimidine has one donor and two acceptors, and Guanine “G” a purine has one acceptor and two donors.
This atoms allows for hydrogen bond between them that gives them structure of DNA molecule.
A nucleotides is hydrogen bonded to T nucleotides while C nucleotides is hydrogen bonded to G nucleotide this is called complementary base pairing.
A student is presented with a model of a digestive system and is asked to remove one structure (small or large organ) that will have the largest impact on decreasing chemical digestion. Which structure should the student remove
Answers
Answer:
Small intestine
Explanation:
Digestion is the process of breaking down food molecules into simpler and usable forms by the body cells. The process of digestion involved the mechanical aspect and chemical aspect. The mechanical one deals with using physical means like chewing to break down the food particles.
However, the chemical one deals with the usage of chemically-secreted enzymes to work on the food molecules. Lots of digestive organs are involved in this chemical digestion, but, the most of chemical digestion takes place in the SMALL INTESTINE. The small intestine is where most of the chemical digestion occurs including absorption.
Hence, according to this question, the student should remove the SMALL INTESTINE because it will have the largest impact on decreasing chemical digestion.

A lichen is an organism that structurally appears to be a single organism. But a lichen is actually two different organisms—a fungus and green algae—living together as one organism. The fungal partner derives its nutrition from the photosynthesizing algae. How does a lichen differ in its photosynthetic activity from Elysia chlorotica, the sea slug that’s considered to be a photosynthesizing animal?
A.
In lichens, the fungi photosynthesize on their own, while Elysia chlorotica forms a relationship with a photosynthesizing plant.
B.
In lichens, the relationship with the algae lasts throughout the life cycle, but in Elysia chlorotica, the relationship occurs only during the immature juvenile stage of the slug’s life cycle.
C.
Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.
D.
In lichens, the association between the fungi and algae is permanent, while Elysia chlorotica associates with a photosynthesizing organism only when it requires food.
Answers
Answer:
B. Cycle
Explanation:
Lichen performs photosynthesis with the assistance of an algal partner, but Elysia chlorotica incorporates the chloroplast from an algal partner, which is how lichens vary from Elysia chlorotica in this regard, hence option C is correct.
How does lichen photosynthesize?A process known as photosynthesis is one in which green plants and some photosynthetic algae produce their own food, glucose, using carbon dioxide and water in the presence of light.
Lichen is a symbiotic association between an algal component that produces food and a dominant partner fungus that gives the lichen its thallus form and fruiting bodies. A particular species of mollusc called Elysia chlorotica uses the chloroplast of an algal partner to carry out the photosynthesis process.
Therefore, Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells, hence option C is correct.

O replication; during the cell cycle
O transcription; in the nucleus of the cell
translation; at the ribosome
transcription; at the ribosome
Answers
Why? - In molecular biology and genetics, translation is the process in which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins after the process of transcription of DNA to RNA in the cell's nucleus. The entire process is called gene expression.
The process is identified by number 1 in the diagram and where in the cell does this process occur is translation, at the ribosome. Thus option 3 is correct.
What is translation?Translation is defined as the process by which a messenger RNA (mRNA) molecule's sequence is converted into an amino acid sequence during protein synthesis.
It is also be defined as when DNA is converted to RNA in the cell's nucleus, the process through which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins. Gene expression refers to the entire process.
Initiation, elongation, and termination are the three phases of an mRNA molecule's translation by the ribosome.
Thus, the process is identified by number 1 in the diagram and where in the cell does this process occur is translation, at the ribosome. Thus option 3 is correct.
