In an old experiment, Jean Baptista van Helmont grew a plant in a pot
that he filled with 200 pounds of soil. After several years, the plant
grew to weigh 169 pounds. The amount of soil in the pot did not
change; it still weighed 200 pounds. Based on your knowledge of
photosynthesis, how did the plant gain most of its weight?
A. The plant gained weight by absorbing nutrients from the soil.
B. The plant gained weight by producing oxygen and storing it.
C. The plant used carbon dioxide to make organic compounds like
glucose, which increased the plant's weight.
D. The plant made carbon dioxide from organic compounds like
glucose, which increased the plant's weight.
Answer:
C. The plant used carbon dioxide to make organic compounds like glucose, which increased the plant's weight.
Explanation:
Plants are mostly autotrophic organisms i.e. have the ability to make their own food via the process of photosynthesis. The food, which s in the form of sugars makes up their biomass. Plants use carbon dioxide (CO2) in the presence of sunlight to make organic compounds such as glucose, which is necessary for growth.
Hence, according to this question, the plant in a pot filled with 200 pounds of soil gained weight and increased to 169 pounds because the plant used carbon dioxide in the process of photosynthesis to make organic compounds like glucose, which increased the plant's weight.
Duchenne Muscular Dystrophy (DMD) is an X-linked recessive trait that causes muscular weakness, deterioration of muscle tissue, and loss of coordination. The allele for DMD is represented by Xd and the normal allele is represented by XD . Neither parent has DMD, but both of their sons express the trait. What are the genotypes of the parents?
Answer:
The correct answer is - XDXd and XD Y
Explanation:
Sex-linked disorders are the disorders that are expressed only when there is two copy of the mutated allele or have not masked by the dominant allele of the gene. In DMD, the dominant allele is XD and the mutated allele is Xd. To express it there are the following genotype possible-
in women XdXd, and in men XdY, so these two genotypes are not possible for the parents in this case. If a mutated allele is present with the dominant allele it will be considered as carrier women but diseased will not be found in them.
So the correct genotype would be
mother: XDXd ( a carrier woman)
father : XDY (normal man)

Why do aquatic organisms have to constantly deal with osmosis
Answer:
Because salt is an agent that attracts and draws out water, the surrounding salt water draws water from inside the fish so they must constantly drink water to replace the lost water in their system. The process of water being drawn out of the body by the surrounding water of higher salt levels is known as osmosis.

An amoeba expels large particles by what process?
A. Diffusion
B. Endocytosis
C. Exocytosis
D. Osmosis
An amoeba expels large particles by EXOCYTOSIS (Option C).
Exocytosis is the process by which large macromolecules are released from the cytoplasm to the cell exterior.Exocytosis occurs via secretory regions of the cell membrane which are able to excrete waste products and other large macromolecules.Conversely, endocytosis is the inverse process by which a cell takes macromolecules from its surrounding environment.The types of active transport that amoebas use to transport macromolecules are endocytosis (in) and exocytosis (out).In conclusion, an amoeba expels large particles by EXOCYTOSIS (Option C).

Cattle and buffalo share a similar fundamental niche, the entire set of conditions under which a population can survive and reproduce. A realized niche is the set of conditions actually used by a given population. Explain what the data in the Venn diagram suggest about the realized niches of the cattle and buffalo and their ability to coexist. Use evidence to support your explanation.
Answer:
The data in the Venn diagram suggest about the realized niches of the cattle and buffalo and their ability to coexist with evidence is discussed below in detail.
Explanation:
2.
From the graph, it is observed that Cattle and Impala have the most overlay in their nutrition.
3.
When Sorensen's index worth is more like 1, there is a contestant among animals for their food manner needs.
From the Venn diagram, we recognize that Cattle and Impala have the most overlay in their nutrition. Also, Sorensen's index worth = 0.82 (closer to 1 concerning other partners.
4.
Sorensen's index for Buffalo and Cattle is 0.48 (cheapest among these 3 partners). So, they are less competitive. So, they can persist and generate easily.

Accuracy in the translation of mRNA into the primary structure of a polypeptide depends on specificity in the ________.a) binding of ribosomes to mRNA.b) binding of the anticodon to small subunit of the ribosome.c) attachment of amino acids to rRNAs.d) binding of the anticodon to the codon and the attachment of amino acids to tRNAs.
Answer:
d) binding of the anticodon to the codon and the attachment of amino acids to tRNAs.
Explanation:
A transfer RNA (tRNA) is one of the three types of RNA molecules whose job is to match an mRNA codon( a sequence of three DNA or RNA nucleotides that corresponds to a specific amino acid) with the amino acid it codes for.
Each tRNA contains a set of three nucleotides called an anticodon which corresponds to the amino acid encoded by a codon of an mRNA. The amino acid encoded by the codon is also attached to the tRNA molecule. This ensures specificity and accuracy during translation.
Therefore, during the translation of mRNA into the primary structure of a polypeptide, accuracy depends on specificity in the binding of anticodon and attachment of amino acids to tRNA.

which element would you expect to be more unstable/reactive, neon or calcium? why?
Answer:
Calcium
Explanation:
Between Neon and Calcium, neon will be more stable compared to the calcium.
Neon belongs to the group of elements on the periodic table called the noble gases. These are the most stable elements and they do not react with other elements.
Calcium on the other hand is reactive It requires a loss of two electrons to attain stability. Therefore, it is a more reactive element.which property of water is most responsible for plants being able to transport water from their roots to their leaves

What other factors did you modify for BEE? Why do you think you need to consider these factors with caloric intake?
Answer:
The activity factor was modified. Ambulating indicates that the person is active. Even small activities require energy. So, people who can walk around and aren’t bedridden expend more calories than people who need to be on bedrest all day. Also, when the stress factor was changed to severe infection, the caloric requirement increased. This increase is probably because the immune system requires more energy to fight off the infection

An anatomy and physiology student, is asked to breathe through a 3-foot long glass tube. What effect does this action have on his blood pH, urine pH, and respiratory rate?
Answer:
If a student breathes through a 3 feet long glass tube it will affect the physiology of the student in various ways such as a change in blood pH, urine pH, and rate of respiration.
It will result in an increase in the normal volume area of the trachea and bronchi as it is a closed system as a face mask. The increase in this dead volume are will result in double the volume of CO2. Decrease the pH of the blood.
When asked to breathe through 3-foot long glass tube there would reduced oxygen available to the tissue (hypoxia) which had the following effects discussed below.
Hypoxia occurs when there is reduced oxygen available to the body tissues.
When asked to breathe through a 3-foot long glass tube, it can lead to hypoxia.
The effect of hypoxia include the following:
Blood pH: Due to increase in anaerobic respiration in the tissues, lactate production increases leading to a fall in blood pH. Urine pH: Hypoxia leads to increase in renal sodium excretion which helps acid-base balance of the body fluid. Respiratory rate: There is significant increase in respiratory rate to compensate for the decreased tissue oxygen levels.Learn more here:

A gene carries the _________ for a trait.
Answer:
A gene carries the information for a trait.
Explanation:
Genes carry the information that determines your traits (say: trates), which are features or characteristics that are passed on to you — or inherited — from your parents. Each cell in the human body contains about 25,000 to 35,000 genes.
A gene carries the information for a trait.
What is gene?The fundamental structural and operational component of heredity is a gene. DNA is the component of genes. Some genes serve as blueprints for the synthesis of proteins. Many genes do not, however, code for proteins.
A few hundred DNA bases to more than 2 million bases make up a gene in a human. Humans are thought to have between 20,000 and 25,000 genes, according to the Human Genome Project, an international research project that aimed to decipher the human genome's sequence and catalog its genes.
Every gene is present in two copies, one from each parent, in every individual. The majority of a person's genes are the same in all persons, but a tiny fraction (less than 1% of the total) are slightly different.
Therefore, A gene carries the information for a trait.

Development typically occurs in a ___________ pattern; however the OTA understands the influence of dynamic systems, including internal and external variables, on development.
Answer:
in a predictable pattern!!
Development typically occurs in a predictable pattern; however, the OTA understands the influence of dynamic systems, including internal and external variables, on development.
Developmental patterns often follow a general sequence and progression across individuals, encompassing milestones in physical, cognitive, social, and emotional domains. This predictable pattern provides a framework for understanding typical development and helps identify potential delays or challenges in various age groups.
Internal variables refer to the individual's genetic makeup, temperament, and personal characteristics, which contribute to the uniqueness of their development. Every person has their own pace and style of progressing through developmental stages, and the OTA considers these individual differences in tailoring interventions and support.

Stars form from what celestial objects ?
Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example, a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. Stars begin their lives as clouds of dust and gas called nebulae. The gravity of a passing star or the shock wave from a nearby supernova may cause the nebula to contract. Matter in the gas cloud will begin to coalesce into a dense region called a protostar.
