Answers
Answer:
At 0.1 to 5.0 μm in diameter, prokaryotic cells are significantly smaller than eukaryotic cells, which have diameters ranging from 10 to 100 μm ([link]). The small size of prokaryotes allows ions and organic molecules that enter them to quickly diffuse to other parts of the cell

Mammals are the only animals that have hair. Would you consider the presence of hair in mammals to be an ancestral or derived trait among all animals? Why?
Answers
Answer:
derived trait
Explanation:
An ancestral (or primitive) trait/character is a feature inherited from the common ancestor of the species/group of interest, while derived traits are those that were absent in the last common ancestor of the group of interest. For example, considering mammals as the target group, the presence of hair is a shared derived trait relative to other vertebrates, i.e., amphibians, reptiles and birds. However, this trait (hair) is ancestral for humans since the genetically closest species to humans (e.g., chimpanzees), also have hair, and they have inherited this trait from a common ancestor.
The presence of hair in mammals is said to be a derived trait among all
animals.
Mammals generally have hairs which is one of their major
characteristics.Animals such as amphibians and reptiles were in existence
before mammals and they had no hair present on their body.
As time went on, changes started to occur as a means to adapt to the living
conditions which gave rise to the development of hairs in mammals and is
the reason why it is a derived trait.

You transformed bacteria with varies plasmids and counted the colonies as well as colony color. All bacteria were plated on media containing ampicillin. See below. Transformed with Colonies observed 1. Plasmid with GFP gene 100 green colonies 2. Plasmid without GFP gene 100 white colonies 3. No plasmid No colonies What conclusions are supported by these results
Answers
Answer and Explanation: GFP gene is a gene that encodes a green fluorescent protein. When bacteria and plasmid are combined, the gene is expressed as observed by the results: plasmid with GFP gene produces colonies with green color; while plasmid without GFP produces white colonies.
Ampicillin is an antibiotic, i.e., bacteria is naturally suscetiple to it.
Plasmid has an ampicillin resistant gene. This is demonstrated in the experiment: when there is plasmid, the gene can be expressed, allowing colonies to grow. But, when bacteria is not combined with plasmid, it is not resistant to the antibiotic, so no colonies are formed.

Answers
Answer:
Gene
Explanation:
A GENE is the unit of inheritance in virtually the cells of all living organisms. It is a segment of DNA that codes for the ability to make one type of protein molecule. In other words, a gene encodes the synthesis of amino acids, which are building blocks of protein.
Genes are naturally found on chromosomes on which they undergo expression i.e. from gene - MRNA (transcription), from mRNA - protein (translation). Hence, based on the question asked, the segment of DNA that carries instructions for protein synthesis is called a GENE.

Describe how many genes and chromosomes can be found in the human body, and how they influence physical appearance and other traits.
Answers
I don’t really have an answer but I have an explanation
Explanation: In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. These pairs of genes then determine certain physical features or traits.
Humans have 46 chromosomes and around 20,000-25,000 genes that determine physical appearance, behavior, and other traits.
What are chromosomes?The human body has 46 chromosomes, which are made up of long strands of DNA that contain the genetic information for an individual. These chromosomes are arranged in 23 pairs, with one chromosome from each pair inherited from each parent.
Each chromosome contains thousands of genes, which are segments of DNA that code for specific proteins that carry out various functions in the body. Genes play a key role in determining an individual's physical appearance, as well as other traits such as susceptibility to certain diseases and personality traits.
Inherited variations or mutations in these genes can lead to differences in physical appearance and traits between individuals. Additionally, environmental factors can also influence the expression of certain genes, further contributing to individual differences.

How does snake venom kill prey? How is venom toxicity measured?
Answers
Answer:
1.Snakes use their venom cautiously, injecting amounts sufficient to disable prey or to defend against predators. Snake venom works by breaking down cells and tissues, which can lead to paralysis, internal bleeding, and death for the snake bite victim.
2.Snake venom and other toxins' strength is measured using the LD50 (lethal dose 50%) test. ... The amount of test substance that kills half the animals gives the LD50 figure. LD50 figures are used, in theory, to indicate the standard toxicity value for each chemical.
Use the graph to describe the effect on temperature as depth increases.
a. As depth increases, temperature remains the same.
b. As depth increases, temperature increases.
c. As depth increases, temperature increases then decreases.
d. As depth increases, temperature decreases quickly at first, but eventually becomes constant.
Answers
Answer:
d. As depth increases, temperature decreases quickly at first, but eventually becomes constant.
Explanation:
As seen on the graph above, the temperature decreased quickly as the depth increased. It is seen between 200 meters to 500 meters in depth. The change in temperature is from 26 degrees to 8 degrees, which is an 18-degree difference. After which, the temperature decrease slows down and becomes constant starting at 2,700 meters going deeper to 4,000 meters. The temperature is being maintained at 1 degree.
The other three choices above (a, b, and c) show both an increase in temperature with an increase in depth. This makes the choices incorrect.

circuit is 12 voltsvhat's the magnitude of the current?
12
36 amperes
0.25 amperes
9 amperes
4 amperes
Answers
Answer:
4 amperes
Explanation:
Using the formula; V = IR
Where;
V = voltage (volts)
I = current (amperes)
R = resistance (ohms)
From the formula; I = V/R
According to the information provided in this question, the resistance of circuit (R) is 3 ohms while the voltage (V) produced by the cell in the circuit is 12 volts.
Therefore, I = 12/3
I = 4 A or amperes.

3. Temperature inversion traps pollution.
4. Cars emit hydrocarbons and nitrogen oxides.
Which answer shows the order in which these steps occur?

Answer:
Photochemical smog.
Explanation:
Photochemical smog occur when the hydrocarbons and nitrogen oxides react with sunlight. The hydrocarbons emit toxic compounds that is present in fossil fuels and nitrogen oxides that is produced due to high temperature and emitted from vehicles when combine with the sunlight produces photochemical smog or ozone. If this smog is present near the surface of earth, it adversely affect our health.
These four steps could result in the formation of this smog leads to photochemical smog.
What causes photochemical smog?Photochemical smog is created when sunlight reacts with nitrogen oxides and at least one volatile organic compound (VOC) in the atmosphere.
Nitrogen oxides come from car exhaust, coal power plants, and factory emissions. VOCs are released from gasoline, paints, and many cleaning solvents
Thus, these steps lead to photochemical smog.
