Answers
the primary cause of eutrophication is the input of nutrient-rich runoff into aquatic ecosystems, which fuels the excessive growth of algae and ultimately leads to oxygen depletion and other negative impacts on the ecosystem which is the first option.
Eutrophication is primarily caused by the influx of nutrient-rich runoff into aquatic ecosystems. This occurs when excessive amounts of nutrients, such as nitrogen and phosphorus, enter the water. The main sources of these nutrients are often human activities, including agriculture, urban development, and wastewater treatment. When these nutrients enter the water, they act as fertilizers, fueling the growth of algae and other aquatic plants.

Mg(ClO3)2-> MgCl2+ 3O2
How many grams of magnesium chlorate would you need to produce 5.00 liters of oxygen?
Answers
Therefore, 5L of O2 at STP is equivalent to (1 mole/22.4 L) x 5 L = 0.2083 mol of O2
From the balanced equation, 3 moles of O2 are produced by heating 1 mole of Mg(ClO3)2
Therefore, 0.2083 mol of O2 is produced by (1/3) x 0.2083 = 0.0694 mol of Mg(ClO3)2.
Molar mass of Mg(ClO3)2 = 191.32 g/mol
Therefore, the mass of Mg(ClO3)2 required is 0.0694 mol x 191.32 g/mol = 13.28 g

what is a CER please help !!!!!!!
Answers
Answer:
Claim-Evidence-Reasoning
Explanation:
hope it helps
Answer:
CER(S) Stands for Claim, Evidence, Reasoning, Science
Explanation:
The 1st part of CER(S) is a CLAIM. A claim is a simple, single sentence that answers a question. Your claim is a statement about what you believe to be true about that question. Your claim must be accurate, clear, and exact. Your claim should be the first sentence in your explanation. Your claim should ONLY answer the question – do not explain your answer at this point.
The 2nd part of CER(S) is EVIDENCE. Evidence consists of data and/or results that can be used to support the claim. Evidence must be explicitly stated in sentence form and cannot merely be referenced. To adequately support a claim, the evidence must be appropriate (relevant to the question) and sufficient (enough provided to be convincing).
The 3rd part of CER(S) is the REASONING. Reasoning ties the evidence to the claim and explains why the evidence supports your claim. In this section you discuss why the evidence that you provided is important and relevant to your claim.
The 4th and final part of CER(S) is the SCIENCE. Your teacher may not ask you to provide the supporting science for every CER(S) question – that is why the S is in parentheses. If you are asked to provide the science that supports your claim, then you need to discuss the relevant science and how it supports your claim.

b. The cell that hemolyzes more quickly loses water at a faster rate.
c. The cell that hemolyzes more quickly acquires NaC1 at a faster rate.
d. The cell that hemolyzes more quickly acquires water at a faster rate.
Answers
The statement that would best explain why one red blood cell hemolyzes more quickly than another is if the cell that hemolyzes more quickly acquires NaCl at a faster rate.
Water moves by osmosis in and out of cells from the region of high water potential or low solute concentration to the region of low water potential or high solute concentration.
A cell with a higher solute concentration than the surrounding solution will keep acquiring water from its surrounding until the cell becomes turgid and bursts or lyses due to over-turgidity.
If the reverse occurs, such a cell will lose water and become flaccid.
Thus, if a red blood cell acquires NaCl, a solute, at a faster rate, such a cell will also acquire water and become turgid/lyses at a faster rate.

What is phenotype?Phenotype refers to the observable physical and behavioral characteristics of an organism, which are determined by the interaction between its genetic makeup (genotype) and the environment. The phenotype can include traits such as height, eye color, body shape, and even personality traits.
These characteristics are influenced by both genetic and environmental factors, such as exposure to sunlight, diet, and other environmental conditions. In many cases, a single gene may have multiple effects on the phenotype, and many genes may work together to produce a single trait. Phenotypic traits can also be influenced by epigenetic changes, which involve alterations in gene expression without changes to the underlying DNA sequence. Understanding the relationship between phenotype and genotype is crucial for fields such as medicine, agriculture, and genetics.

What is the final product of transcription?
A gene
An amino acid
An mRNA molecule
A stop code
here is the paragraph to read from:
Transcription is the process by which an RNA copy of a gene sequence is created. This copy, known as the mRNA, travels from the cell nucleus to
the cytoplasm. There, it directs the synthesis of the protein. The base code in the mRNA controls the order of the amino acids in the protein.
There are 20 amino acids used to make proteins and different codes for each acid. The tRNA reads the code. Then it brings a specific amino acid to
attach to the growing chain of amino acids. Each tRNA carries only one type of amino acid. It only recognizes one specific code. tRNA is released
from the amino acid until it comes to a stop code. Then the protein is set free from the ribosome.
Answers
Answer:
An mRNA molecule
Explanation:
Transcription is a process by which the information stored in a specific fragment of DNA called 'gene' is used to produce a complementary RNA molecule, usually a messenger RNA (mRNA). Subsequently, this mRNA is used as template to produce a polypeptide chain (i.e., a sequentially ordered amino acid chain) through the process of translation. A stop codon, also known as termination codon, is a triplet of nucleotide bases within an mRNA that signals the end of the protein when it is synthesized in the ribosome. There are three stop codons (UAG, UAA, and UGA) that are capable of stopping protein synthesis.

Why is it hard to regain a trait that has been lost? This is an evolutionary bio question!!
Answers
It is hard to regain a trait that has been lost because the genetic changes required to evolve a new trait or to regain a lost trait are often complex and can involve multiple genes and regulatory elements. Furthermore, evolution is a slow, laborious process that requires beneficial mutations to accumulate over many generations.
When a trait disappears, the genetic material encoding it may also disappear or become inactive, making it more challenging for the trait to reappear in subsequent generations. For example, restoring a species' ability to manufacture a specific enzyme required for a particular metabolic pathway can be challenging if the genetic changes required to do so are complex.

There is decrease in the O2 content in the air at higher elevations. The condition is called as hypoxia when the body is deprived of sufficient amount of O2 supply. The reaction of the lungs is to tighten the blood vessels and thereby cause an increase in breathing rate or hyperventilation. The breathing is called as high-altitude periodic breathing (PB). Adaption of the body to this kind of phenomenon is the increase the RBC production and decreasing the binding capacity of hemoglobin. This will eventually lead to increase in breathing rate.
Why does a cat comes near when show it milk and runs away when you show it stick ?
Answers
Cats have evolved certain behaviors that are influenced by their natural instincts and experiences.
When a cat sees milk, it may be attracted to it because it contains nutrients that are important for its survival, and the cat may associate the presence of milk with positive experiences. This can include nursing from its mother as a kitten or catching and consuming prey that contains milk or milk products.
On the other hand, when a cat sees a stick, it may perceive it as a threat or danger, and may associate it with negative experiences, such as being hit or attacked by a predator. This can trigger the cat's natural instinct to flee or hide from potential danger, as a survival mechanism.
Overall, a cat's behavior is influenced by its instincts, past experiences, and environmental cues. It may approach things that it perceives as positive or beneficial, and avoid or flee from things that it perceives as dangerous or threatening.
