[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]

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

Answer:

first the car starts with potential energy when the car starts to move which is kinetic energy and when you come to a sudden stop you will get yanked forward because one of Newton's law are that what is in motion stays in motion.

Explanation:

Answer:

a lunar eclipse

Explanation:

The shadow that Aristotle saw was caused by a lunar eclipse. At that time the sun, earth, and the moon nearly straight alignment caused the Earth's shadow to be reflected on the moon. This shadow is what ultimately led Aristotle to believe that the Earth was a sphere. This should not be confused with a solar eclipse which is similar but instead the sun, moon, and earth align in that order which causes the moon to completely block the sun to anyone on earth.

Question 1 Answer: Increases genetic variation

Question 2 Answer: Faster Reproduction rate and Requires less energy (it is more time and energy efficient as a mate is not required)

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.

Answer:

Hooke the first was correct

CHGGYGYGYGUIYGUYGTUYGUYGUYG

Answer:

Well the most common is habittat destruction. With the number of humans only growing, more land is needed and habitat desturctions occur. Lack of food is also a problem, as some crops don’t grow as much so the bee’s food source is smaller which leaves thousands dead. Also if the food source doesn’t run out, there are pesticides sprayed and the bees will die if eaten one which the chemical properties in a pesticide will kill. Also if not used, littering, if you dump it into a water source, the water gets contaminated and the bees could die from that, or the water spreads ano the flower would receive this chemical property, which could kill the Bee’s food source, or the flower doesn’t die but when the bees consume it, the bee will die.

Answer:

No sounds can be heard in outer space because sound waves require a medium, such as air, to travel through.

Explanation:

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.

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.

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.

a. Biological Anthropology

3. The way this research might contribute to a comparative anthropological approach is:

a. This research could be used to compare soybean consumption in other parts of the world.

Explanation:

Cultural anthropology studies the interaction between human beings and their surrounding social ideas, behaviors, and physical environments.  Biological anthropology studies the physical, biological, and behavioral aspects of human beings and other primates.  These two are part of the four fields of Anthropology.  Others include archaeological and linguistic anthropologies.

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.
