2. Give ONE possible reason, biotic or abiotic, why the population decreased in 1990
after it had reached its carrying capacity.
Answer:
availability of resources.
Explanation:
Availability of resources is abiotic factor which is responsible for the decrease in population in 1990 because when the population reaches its carrying capacity so the organisms compete with each other and due to limited resources such as food etc the decrease occurs in population. Infection is also occurs when there is high population due to which death occurs and population of organism decreases.

Which of the following statements best summarizes the factors that affect population growth?
A. When resources are available, populations grow until they reach carrying capacity.
B. The more limiting factors affect a population, the greater the population growth.
C. The carrying capacity will decrease when there are no limiting factors affecting the population.
Answer:
A
Explanation:
Before we try to answer the question lets define a few key terms
Key Terms:
Carrying capacity - The max population that can be sustained by the amount of resources in a specific environment
Limited factor are usually expressed as a lack of a particular resource.
Now lets look back at the answer choices
For A,
A. When resources are available, populations grow until they reach carrying capacity.
This statement makes sense because with available resources, a population will continue to increase until the amount of resources isn't enough for the population, in other words the population will increase until its reached its carrying capacity. So this might be the answer, however lets look at the other answer choices just in case.
For b,
B. The more limiting factors affect a population, the greater the population growth.
This statement would not be true because limiting factors usually are expressed as a lack of a particular resources. A lack of resources ( more limiting factors ) would lead to a population decreasing, not increasing, therefore B is not a true statement
For C,
C. The carrying capacity will decrease when there are no limiting factors affecting the population.
This statement would not be true because if there are no limiting factors ( which remember are expressed as a lack of particular resource ) the carrying capacity ( or the max population that can be sustained by the amount of resources in a specific environment ) would not change at all because there are no limiting factors changing the availability of the resources, therefore C is not the answer.

enveloped viruses are released from the host cell by lysing the host cell which results in immediate cell death.T/F
The given statement "enveloped viruses are released from the host cell by lysing the host cell which results in immediate cell death." is False.
Enveloped viruses:
Enveloped viruses can be released from the host cell by both lytic and non-lytic processes, such as the budding process. The budding process allows the virus to exit the host cell without immediately causing cell death. During the budding process, the virus acquires its envelope from the host cell membrane, and the newly formed virus particles then leave the cell. This process allows the host cell to remain alive and continue producing more viruses. Lysis of host cell refers to the destruction of the cell, which is more commonly associated with non-enveloped viruses.

General Overview of Kidney Functions Complete the sentences describing the functions of the kidneys.
The kidneys are vital organs that are responsible for filtering the blood and removing waste products from the body. They are located on either side of the spine in the lower back.
Kidneys perform several functions, which are discussed below:
1. Excretion of Waste Products: The kidneys filter blood to remove waste products like urea, creatinine, and excess salts from the body.
They also help regulate the amount of water in the body.
2. Regulation of Blood Pressure: Kidneys regulate blood pressure by producing a hormone called renin that constricts blood vessels. This constriction increases blood pressure, which is essential for the proper functioning of the body.
3. Production of Hormones: Kidneys produce hormones like erythropoietin, which stimulate the bone marrow to produce red blood cells, and calcitriol, which is essential for the absorption of calcium from the gut.
4. Acid-Base Balance: Kidneys help regulate the pH of the body by excreting acids and bases as required. They also produce bicarbonate ions that buffer excess acid in the body.
5. Electrolyte Balance: Kidneys help maintain the balance of electrolytes like sodium, potassium, calcium, and magnesium in the body. They excrete excess electrolytes and retain the ones that are required.
Overall, the kidneys are essential organs that play a crucial role in maintaining the balance of the body's internal environment.

1.) Which of the following E. coli proteins is responsible for advancement of the mRNA during translation?
IF1
IF2
EF-Tu
EF-G
None of the above.
The protein responsible for the advancement of mRNA during translation in E. coli is EF-G (D). Here option D is the correct answer.
During translation, mRNA advancement is facilitated by a protein called EF-G (Elongation Factor G) in E. coli. EF-G plays a crucial role in the translocation step of translation, where the ribosome moves along the mRNA template, allowing for the synthesis of a polypeptide chain.
EF-G functions by binding to the ribosome after a peptide bond is formed between the growing polypeptide chain and the incoming amino acid. This binding causes a conformational change in the ribosome, which allows the mRNA and tRNA complexes to move one codon forward, positioning the next codon in the ribosome's decoding site.
By promoting this movement, EF-G facilitates the continuous elongation of the polypeptide chain during translation. It helps to maintain the reading frame and ensures accurate and efficient protein synthesis.

if all cells contain the exact same copy of DNA, how do they become specialized?
Even if all the cells have the same DNA they biochemical function are different, that's because differents sets of genes must be turned on and off in each cell type by the action of enzymes and other molecules. Each cell have the same 20,000 or so genes but they are biochemically selected by the action of molecules as hormones and chemical signaling. Therefore, different cells use different parts of the DNA code as directions.
thyroxine can trigger growth, temperature tolerance, or osmoregulation depending on the organism in which it is produced. which is the most likely mechanism for such diverse responses in different organisms?
The primary hormone that the thyroid gland releases into the bloodstream is thyroxine. It is the inactive form, and organs like the liver and kidneys convert the majority of it into the active form triiodothyronine.
The body's metabolism, cardiac and digestive processes, muscle control, brain growth, and bone maintenance are all significantly regulated by thyroid hormones.
Hypothyroidism refers to the thyroid gland producing too little thyroxine. It could be brought on by autoimmune conditions, inadequate iodine consumption, or the use of specific medications. Sometimes there is no known cause. Untreated throxine before birth or during infancy can result in mental disability and stunted growth because thyroid hormones are crucial for both physical and mental development.
Adult hypothyroidism results in a slower metabolism. It may cause symptoms like weariness, a diminished ability to tolerate cold conditions, a low heart rate, weight gain, decreased appetite, impaired memory, sadness, muscle stiffness, and decreased fertility.

B. The mind is a general-purpose device that can be applied equally to a vast array of problems.
C. All behaviors that were adaptive for our prehistoric ancestors serve us well today.
D. Evolution has not impacted human development.
The correct statement about evolutionary developmental psychology is that many evolved psychological mechanisms apply only to a specific aspect of a person's makeup.
The statement A is true in the context of evolutionary developmental psychology. Evolutionary developmental psychology suggests that human psychology has been shaped by the process of evolution, and various psychological mechanisms have evolved to solve specific adaptive problems faced by our ancestors. These evolved mechanisms are not necessarily general-purpose devices that can be applied equally to all situations (as stated in option B). Instead, they are often specialized to address particular aspects of human behavior, such as social interaction, mating, or parental care.
Option C is incorrect because not all behaviors that were adaptive for our prehistoric ancestors necessarily serve us well today. While some adaptive behaviors may still be relevant and beneficial in our current environment, others may be maladaptive or no longer advantageous. Human societies and environments have changed significantly since our ancestors' time, and what was once adaptive may not be so in the present context.
Option D is also incorrect. Evolution has undeniably impacted human development. The evolutionary process has shaped various aspects of human biology, including our physical features, cognitive abilities, and psychological predispositions. Evolutionary developmental psychology explores how these evolutionary influences interact with developmental processes to shape human behavior and psychological traits. It recognizes that humans are products of both genetic inheritance and environmental influences, and that the interplay between the two has shaped our developmental trajectory.
