Answer with Explanation:
The large sample size allowed Gregor Mendel to make comparisons quantitatively. The "margin of error" is narrower and it allowed him to detect statistically significant results through its statistical power. Large sample sizes have a greater statistical power. However, it takes a lot of time, effort and money. Mendel was very persistent and had the driving force. This allowed him to develop the "Three Principles of Inheritance."
A smaller sample size doesn't give a significant difference because the samples are quite random. This has a tendency to mask the result.

Explanation:
Which hypothesis do the similarities in the bone arrangements support?
a. These organisms are members of the same species.
b. These organisms may have descended from the same ancestor.
c. These organisms have adaptations to survive in different environments.
d. These organisms all contain the same genetic information.
Answer:
B
Explanation:
A similarity in the arrangement of bones in organisms can be hypothesized to be an indication of the organisms descending from the same ancestor.
The similarity in the arrangement of bone in different organisms is one of the morphological evidence used to support the theory of organic evolution which says that all living organisms are of the same descent with modification from common ancestors.
The similarity in the arrangement of bones falls under homology. Homologous organs are similar in structures but different in functions. For example, the pentadactyl limbs of vertebrates. Mammals, birds, reptiles, and amphibians all have limbs that are built on a five-digit plan but the functions of the limb vary within and among different groups of vertebrates.

This scientist looked at cork and used the term "cells" to describe what he saw *
Answer:
Robert Hooke.
Explanation:
Robert Hooke is a British scientist and he was the scientist that looked at cork and used the term "cells" to describe what he saw in 1665.
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Generally, cells have the ability to independently replicate themselves. In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles and they include cell membrane, nucleus, golgi apparatus, cytoplasm, ribosome, lysosome, chromosome, etc.

Which best explains why water quality standards have been created to ensure heavy metals in water are kept to a minimum?
O A. Heavy metals are linked to toxicities in humans and large amounts of heavy metals should not be consumed.
OB. Heavy metals can stain ceramic surfaces in homes and cost the homeowners hundreds in repairs.
OC. Heavy metals can cause discoloration of water and can cause a strong unpleasant odor.
O D. Heavy metals can corrode pipes and cause problems with internal plumbing.
its OB because if you read it says it praticly
Heavy metals are harmful and should not be consumed in large amounts. Therefore, option (A) is correct.
What are harmful effects of heavy metal in water?The flow of groundwater and surface water, as well as seepage and runoff from the surface, can introduce heavy metals into private wells. People who consume significant quantities of heavy metals put themselves at risk for acute and chronic toxicity, as well as anemia, cancer, and damage to their liver, kidneys, and intestines.
Heavy metals in water are usually treated using methods like chemical precipitation, flotation, adsorption, ion exchange, and electrochemical deposition. Most of the time, heavy metals are taken out of inorganic effluent by a process called chemical precipitation.

The color of a light wave is determined by its wavelength. On the COLOR tab, slowly drag the Light wavelength slider back and forth and observe the effect on oxygen production. How does the color of light affect the rate of photosynthesis
Answer:
The color of light determines how effective chlorophyll pigment will be at absorbing light.
Explanation:
Photosynthesis is a metabolic process that requires light, which is an electromagnetic radiation. Light on the electromagnetic spectrum is determined by wavelength. Each region/color of light occurs at a specific wavelength.
Hence, chlorophyll pigment, which is the major photosynthetic pigment effectively absorbs blue and red light in the visible light region of the electromagnetic spectrum. Hence, the rate of photosynthesis will be affected negatively if the color of light is not the one stated above.
Mutations result in changes to genotype that can result in changes in phenotype. Explain how a mutation causes a change in the genotype of an organism AND may result in a change in the phenotype of an organism.
Answer:
A mutation can alter the structure/function of a particular protein, thereby also altering the phenotype resulting from this new variant
Explanation:
A mutation can be defined as a genetic change in the genome of an organism. Some mutations are capable of modifying the expression and/or structure of the proteins, while other mutations (known as silent mutations) have no effect on the resulting proteins. When mutations occur within the gene region encoding a protein (i.e., exons), they are potentially capable of producing a faulty protein. For example, a mutation can alter the Open Reading Frame (ORF) of the resulting protein, thereby inactivating it. The mutations that alter the structure and/or function of the protein can also alter the resulting phenotype associated with the expression of this protein. For example, a mutation within a gene that encodes a key enzyme can potentially alter the binding site of the protein, so the resulting mutated enzyme cannot bind to the substrate anymore. In consequence, this mutation alters the phenotype of the individual who is not more able to carry out the metabolic reaction catalyzed by the faulty enzyme.

dihybrid cross trihybrid cross both none
Answer:
a. none
b dihybrid and trihybrid crosses (both)
c. trihybrid cross
d. none
e. dihybrid cross
Explanation:
A dihybrid cross can be defined as a mating experiment between two different varieties/lines that differ in two observed phenotypic traits, while a trihybrid cross is a cross between two varieties/lines that differ in three traits. For example, Mendel crossed two pea plants that differed in seed color (yellow and green) and seed shape (wrinkled and round). Mendel's experiments consisted of dihybrid and trihybrid crosses for different phenotypic traits. From these mating experiments, he observed dihybrid F1 plants produced 9:3:3:1 ratio of phenotypes in the F2 generation.

HURRRRYYYp
Answer:
The first statement is true, while the second statement is false.
Explanation:
Every living organism needs a particular amount of food in order to be able to survive. Each species though has its own different requirements, and there are great variations that occur because of size, lifestyle, is the organism cold-blooded or warm-blooded, etc.
In this case, we have to examples. In the first one, a single mouse needs 4 square meters of grass in order to stay healthy. In order to get the amount of grass needed for fifty mice, we just need to multiply the number of mice by the amount of grass needed for one of them:
50 x 4 = 200
We got 200, meaning that 200 square meters of grass will support a population of 50 mice.
In the other case, a single snake needs 10 mice in order to stay healthy. To get a result how many mice are needed for 10 snakes, again we just need to multiply the number of snakes by the number of mice a single snake needs:
10 x 10 = 100
We got 100, meaning that 10 snakes need 100 mice in order to stay healthy.
A biologist examines a series of cells and counts 160 cells in interphase, 20 cells in prophase, 6 cells in prometaphase, 2 cells in metaphase, 7 cells in anaphase, and 5 cells in telophase. The complete cell cycle requires 24 hours. Match the average duration to the appropriate cell cycle stage in these cells. M phase prophase metaphase telophase 4.8 hours 14.4 minutes 2.4 hours 36 minutes
Answer:
M phase: 4.8 hr
Prophase: 2.4 hr
Prometaphase: 0.72 hr
Metaphase: 0.24 hr
Anaphase: 0.84 hr
Telophase: 0.6 hr
Explanation:
Mitosis, also known as M phase, is the process of nuclear division after interphase, which is followed by cytoplasmic division via cytokinesis. Mitosis can be subdivided into the following phases: Prophase, Prometaphase, Metaphase, Anaphase, and Telophase. In this case, 160 cells are in interphase (for a total of 200 cells), thereby 40 cells are in mitosis >> 200 - 160 = 40 cells. Since the complete cell cycle requires 24 hours, it is possible to calculate the average duration of each phase:
M phase: 40/200 = 0.2 x 24 hr = 4.8 hr
Prophase: 20/200 = 0.1 x 24 hr = 2.4 hr
Prometaphase: 6/200 = 0.030 x 24 hr = 0.72 hr
Metaphase: 2/200 = 0.01 x 24 hr = 0.24 hr
Anaphase: 7/200 = 0.035 x 24 hr = 0.84 hr
Telophase: 5/200 = 0.025 x 24 hr = 0.6 hr
Anthropologists have been studying the role of soybean curd and related products in the culture of Hong Kong. The researchers interview people about how frequently they eat soybean products, where they eat them (at home or in restaurants), and during what time of day they eat them. The researchers also ask people about how they prepare soybean products, where they obtain soybean products, and any beliefs they might have about the soybean products (such as their nutritional value). The data are used to assess the role of soybean products in the culture. The researchers are also considering how their findings relate to global soybean consumption patterns.

If the fraction of base pairs devoted to protein-coding genes is the same as the fraction of the total genes that they represent, what is the average number of base pairs per protein-coding gene
[tex]\mathbf{Here \ is \ the \ missing \ part \ of \ the \ question} \\ \\ \mathbf{The \ genome \ of \ Escherichia \ coli \ consists \ of \ 4380 \ genes, \ encoding \ 4290} \\ \\ \mathbf{ proteins, \ in \ jus t \ 5175720 \ base \ pairs. \ What \ percent \ fraction \ of\ the} \\ \\ \mathbf{ Escherichia \ coli \ genes \ encode \ proteins?}[/tex]
Answer:
1182
Explanation:
From the information given:
Number of present genes = 4380
the total no. of protein-encoding = 4290
Total no. of base pairs = 5175720
The percentage fraction of genes encoding the protein is;
total no of protein-encoding gene/total no of present genes
[tex]\mathbf{\dfrac{4290}{4380} = 0.9795}[/tex]
= 97.95%
The average number of base pairs per protein-coding gene is;
= total no. of base-pair/ no of present genes
[tex]\mathbf{ \dfrac{5175720}{4380} = 1181.6} \\ \\ \simeq \mathbf{1182}[/tex]
