Since its inception, the theory of evolution has been the subject of frequent debate. Those who oppose evolutionary theory often point to gaps in the
fossil record in an attempt to discredit the theory. Which statement would be the best counterargument as to why the fossil record can be relied upon to
support evolution?
The fossil record provides evidence that extinct species only fossilized during certain geologic eras.
The fossil record provides evidence that extinct species are genetically identical to current species.
The fossil record provides evidence of many different types of organisms, since most species fossilize well.
The fossil record provides evidence of many transitional organisms that show relationships between species
Answers
Answer:
There are lots of transitional organisms in the fossil record though it does take very specific and precise conditions for a fossil to be preserved, a deer that dies in a field will not end up in the fossil record so we are looking at a small sampling of the evidence (and a good thing too or there wouldn't be anywhere to walk with all the bones laying around)

Ecologists are interested in quantifying different kinds of biodiversity. In each of the two studies outlined here, which kind of biodiversity are ecologists studying?
a. Ecologists draw blood samples from basking shark (Cetorhinus maximus) specimens caught from a single large population in the Atlantic Ocean. From each blood sample, the ecologists isolate DNA. Comparing several DNA sequences across the individuals that were sampled, the ecologists are able to estimate the variation in DNA sequences in the entire population.
b. Ecologists establish 20 small areas, called plots, randomly scattered across a California grassland. They count the number of different plant species present in each plot. By noting how many species appear in the plots, the ecologists are able to estimate the number of species in the entire grassland.
Answers
Answer:
The correct answer is -
A. Genetic diversity.
B. Species diversity
Explanation:
In the first study, ecologists are studying the DNA sequences of the basking sharks and comparing the DNA they collected from the blood sample for finding the variation in DNA. The study of DNA and comparing the variations of DNA of a species is studying the genetic diversity of the species.
In the second study, the ecologists tried to study the different types of species present in small patches or plants, they created small patches of land, it is the study of species diversity.

Answers
Answer:
because DNA can't leave
Explanation:
Transcription must occur where deoxyribonucleic acid (DNA) can be found: A. because DNA can't leave.
What is transcription?Transcription can be defined as a biological process that typically involves re-writing the information contained within a deoxyribonucleic acid (DNA) into a ribonucleic acid (RNA) by enzyme RNA polymerase.
Generally, the Transcription of deoxyribonucleic acid (DNA) produces a single-stranded ribonucleic acid (RNA) molecule that is the same with the strand of DNA used as the template.
In conclusion, transcription must occur where deoxyribonucleic acid (DNA) can be found in living organisms because DNA can't leave.

The Big Five personality factors are five ranges of key personality traits. Describe each of the five factors. Then, describe how stable the traits are and how heritable they are.
Answers
Answer:
The big five traits are:
1- extraversion
2- neuroticism
3- agreeableness
4- openness
5- conscientiousness
Explanation:
The Big Five personality traits, also called the OCEAN model, is a widely accepted theory in psychology that states that personality can be reduced into 5 major factors: extraversion, agreeableness, openness, neuroticism and conscientiousness. Agreeableness refers to the manner in which one person treats other people. Conscientiousness refers to the ability to control impulses. Extraversion refers to the sociability level. Openness refers to the willingness for new experiences. Neuroticism refers to the person's emotional stability. These five traits are relatively stable during lifetime. Moreover, it has been shown that the Big Five traits are affected by both genetic factors (family) and cultural factors (education) in a proportion of 50:50. In consequence, approximately half of the differences observed between individuals result from genetic inheritance and half from environment.

Answers
Answer:
The least numerous but the largest of the papillae are arranged as a V-shape on the posterior dorsal surface of the tongue. They contain the majority of taste buds and are called vallate papillae.
Explanation:
The shape, location and function of these taste buds make vallate papillae unique. First, they have a distinctive "v" shape, and most adults only have seven to twelve of these papillae, vallate papillae are the least numerous papillae, they are the recipients of the bitter taste. The vallate papillae are the largest and the most specialized, they are located on the back of the tongue, forming the lingual V, in a variable number from 7 to 12. The number of taste buds depends on age, presenting around 270 in the newborn and descending approximately one hundred in individuals older than 75 years. These buttons are located in the crypts or grooves that form the papillae, mainly on their internal face (the annular groove is observed between the papilla and the edge of the calyx), in whose edges the extremities of the taste corpuscles stand out in the form of filaments. Each taste corpuscle comprises two classes of cells: supportive and taste cells.
The largest but least numerous papillae in the dorsal surface of the tongue is Vallate papillae.
Vallate papillae:
These are specialized taste buds that present in the posterior dorsum of the tongue.
They are the largest taste buds. They form a 'V'- shape structure.There number can vary between 7- 12.Therefore, the largest but least numerous papillae in the dorsal surface of the tongue is Vallate papillae.

A) Sandstone. Sandstone has more obvious layers of sediments.
B) Shale. Shale is fine grained and is more likely to dissolve in water.
C)Sandstone. Sandstone is made of large sand-like grains and is easily eroded by wind
D)Shale. Shale contains iron which is an element that easily combines with the oxygen in the atmosphere to produce rust.
Answers
Answer: A) Sandstone. Sandstone has more obvious layers of sediments.
Step by step explanation: As you take a look at the given pictures, you notice that (Sandstone) Is more closed off than (Shale). So whenever rain comes, rain will seep into the little openings of the rock shale has, causing it to break down.Same for strong wind, since shale isn't as compacted as Sandstorm, then shale will not last very long. Therefore making Sandstone being able to undergo more harsh conditions.

EMB agar is a medium used in the identification and isolation of pathogenic bacteria. It contains digested meat proteins as a source of organic nutrients. Two indicator dyes, eosin, and methylene blue inhibit the growth of gram-positive bacteria and distinguish between lactose fermenting and non-lactose fermenting organisms. Lactose fermenters form a metallic green or deep purple colonies, whereas the non-lactose fermenters form completely colorless colonies. EMB agar is an example of which of the following?
a. a selective medium onlyb. a differential medium onlyc. a selective medium and a chemically defined mediumd. a selective medium, a differential medium, and a complex medium
Answers
Answer:
a selective medium, a differential medium, and a complex medium
Explanation:
EMB Agar (Eosin Methylene Blue Agar) is both a selective and differential culture medium that slightly inhibits Gram-positive bacteria and can be used to distinguish bacteria capable of fermenting lactose from those that are unable to ferment this disaccharide. This medium is commonly used for isolation and differentiation of coliforms (i.e., bacteria found in the soil and water samples) and fecal coliforms (bacteria found in the gut and feces samples). In EMB agar, lactose-fermenting-gram-negative bacteria (e.g., E. coli) will form colored colonies, while non-lactose-fermenting-gram-negative bacteria will form colorless colonies (e.g., Salmonella). EMB agar is composed of lactose, gelatin, methylene blue dye and eosin Y dye ( a xanthene dye) .

Knowing that the genetic code is universal, scientists use molecular biological methods to insert the human beta-globin gene into bacterial cells, hoping the cells will express it and synthesize functional beta-globin protein. Instead, the protein produced was nonfunctional and is found to contain many fewer amino acids than does beta-globin produced by eukaryotic cells. Explain why.
Answers
Answer is given below :
Explanation:
When the beta-globin gene is inserted into the bacterial chromosome, during insertion, beta-globin forms a stop codon between the coding sequences of beta globin, resulting in a reduced amino peptide. Acid on translationFurthermore beta-globins form a tertiary protein complex with alpha-globin, which in addition to the ham-subgroup forms functional hemoglobin. Since we only put the beta-globin gene on the bacterium-chromosome that is not enough to make a functional protein, we found a non-functional proteinWhy do animals become adapted to their environments?
