the answer is A
Explanation:
Heterozygous alleles are found on ________ chromosomes
Answer is Homologous.
A diploid individual having two different alleles for a specific trait is called heterozygous. An allele is the alternative form of the same gene. The cells in diploid organisms contain sets of homologous chromosomes, which are paired chromosomes. Each chromosome of a homologous pair has the same genes on the same positions. Although homologous chromosomes have the same genes, they may have different alleles for those genes.
Example: The gene for seed color trait in a pea plant exists in pair. One gene or allele for yellow seed (R) and the other for green seed color (r). A heterozygous plant would contain alleles for seed color (Rr). Gene R is present one chromosome and its allele (r) is present on the other chromosome of the homologous pair.

a.therapeutic communities
b.medical detoxification clinics
c.matrix communities
d.all of these are correct.
Answer is a. therapeutic communities.
Therapeutic communities are a common form of long-term residential treatment for substance use disorders. These communities provide drug-free environments in which people with addictive problems live together in an organized and structured manner to promote change toward recovery and re-socialization. Some such groups evolved into self-supporting and democratically run residences to support abstinence and recovery from drug use.

Where are new skin cells produce to replace old cells that have been shed?
The production of the new skin cells occurs at the basal layer of the epidermis.
The skin is composed of three layers:
1. The epidermis- The outermost layer of the skin. Waterproof with the protective role and which serves as a barrier to infection. It also has its own layers (from the top): stratum corneum, stratum lucidum (only on hands and bottoms of feet), stratum granulosum, stratum spinosum, stratum basale.
The cells of stratum basale are constantly going through mitosis to produce new cells (keratinocytes) and as new cells are formed, the existing cells are pushed superficially away from the stratum basale.
2. The dermis,

A herpetologist wants to estimate how many snakes are in a forest. She counts 12 snakes in a 100,000 square foot area. Estimate how many snakes are in the entire forest of 7,000 acres.
(1 acre = 43,560 square feet)
Please help me solve thus
Answer:
Approximately 36 522
Explanation:
First convert 100 000 square ft to acres = 2.3
Using ratio method:
[tex]x = \frac{12 x 7000}{2.3} \\ = 36 521.7[/tex]
How do mirnas function in controlling gene expression? view available hint(s) how do mirnas function in controlling gene expression? by binding to dna and preventing transcription of certain genes?
miRNAs are key components in gene regulation, working not by binding to DNA but by binding to mRNAs post-transcription. Their interaction with mRNAs results in mRNA degradation or inhibition of translation, suppressing specific gene expression.
Explanation:MicroRNAs, commonly referred to as miRNAs, play a crucial role in the regulation of gene expression. Unlike the student's proposition, miRNAs do not generally bind to DNA. Instead, they function by binding to messenger RNAs (mRNAs) after transcription has occurred. The interaction between the miRNA and the mRNA typically results in the mRNA's degradation or the inhibition of its translation into a protein, thus preventing the expression of the corresponding gene.
These small non-coding RNA molecules are key components in the post-transcriptional regulation of gene expression, and can suppress the expression of specific genes through a process known as RNA interference. The ability of miRNAs to control gene expression makes them important regulators of various biological processes, including cell growth, differentiation, and apoptosis.

when did the human population begin to grow at a faster rate than at any other time in history
During the industrial revolution, the population of the Western world started to increase quickly. Since the 1950s, the population of the world has increased significantly.
Which period saw the fastest growth in the human population?The world population doubled at the quickest rate between 1950 and 1987, growing from 2.5 to 5 billion people in just 37 years. This represents a population increase of around one generation. During this time, population growth peaked in 1962 at 2.1%.
When did the exponential growth of the human population begin?The population doubled in the 19th century, tripled in the 20th century, and reached 6 billion in the year 2000. This exponential increase was caused by breakthroughs in medicine, science, and the economy.

Final answer:
The human population began growing at an unprecedented rate during the Industrial Revolution in the late 18th century, accelerating during the 20th century, primarily due to technological, agricultural, and medical advancements that improved living conditions and life expectancy.
Explanation:
The human population began to grow at a faster rate than at any other time in history around the start of the Industrial Revolution in the late 18th century. This marked the beginning of what is often called the population explosion. Advancements in technology, agriculture, and medicine have all contributed to exponential growth. The global population growth rate accelerated further during the 20th century and continues to grow in the 21st century. The shift from very slow growth to rapid increase can be visualized by the shape of a J-curve in population graphs.
For example, it took millennia for the human population to reach 1 billion around 1800 CE, and only a little over a century later, the population reached 2 billion. Within less than another century, an additional 5 billion were added, showcasing the exponential nature of recent population growth. Scientific advancements and industrialization played significant roles in creating conditions for the population to grow at previously unseen rates, which includes improved health care, increased food production, and better sanitation.

Water-soluble nutrients absorbed into the blood are routed directly from the small intestine through the portal vein to the __________ before any other organ.:
Final answer:
Water-soluble nutrients absorbed from the small intestine are sent directly to the liver via the portal vein for processing before reaching other parts of the body.
Explanation:
Water-soluble nutrients that are absorbed into the blood are sent directly from the small intestine through the portal vein to the liver before any other organ. The hepatic portal system is a critical component in the body's nutrient distribution system, where the liver acts as a processing plant. Nutrient-rich blood from the small intestine, where most absorption occurs, reaches the liver for detoxification, storage, or metabolic processing before being circulated to the heart and throughout the body.
