Why do viruses not fit easily into the broadest taxonomic category, life? (Choose all that apply)
1. They are not made of cells.
2. They have a capsid.
3. They do not reproduce on their own.
4. They do not respond to stimuli.
Answer:
viruses are not fit into broadest taxanomic system because:
they are not cells
they do not reproduce their own
they do not respond to stimuli.
Explanation:
viruses have capsid and are not cells. to be a cell they must have a cell membrane while viruses lack cell wall. they replicate by using the host machinary in which they are causing infection. they are acellular and obligate intracellular parasites of anials plants fungi and bacteria.
Answer:
they are not cells
they do not reproduce their own
they do not respond to stimuli

The pH scale ranges from ____________ to ____________ and is used to indicate the ____________ of a solution.
Answer:
Acidic, Basic, acidity
Explanation:
The PH scale ranges from acidic to basic and is used to indicate the acidity/alkalinity of a solution.
A normal PH scale ranges from the number 0 to 14. When the PH of a solution ranges from 0 to 7 is said to contains acidic contents in it. If the solution is greater than 7, it is said to be alkaline and when the solution is average(7) it is said to be neutral solution.
Example of an acidic substance/solution is lemon juice, solution that contain alkaline is bleach.

The excited electron then loses its energy as it travels down the
The excited electron then loses its energy as it travels down the Then, at some point, these higher energy electrons give up their "extra" energy in the form of a photon of light and fall back down to their original energy level.
What happens to an electron when it loses energy?
The lines in an emission spectrum occur when the electron loses energy, and "falls back", from a higher energy state to a lower one emitting photons at different frequencies for different energy transitions.
How can an electron in an atom lose energy?For an isolated atom or molecule in a gas, excited states of electrons often don't have any easy way to lose energy except by electromagnetic radiation- the light of some frequency. A little of the energy can go into internal vibrations for a molecule.

g One benefit of operons in bacteria is that they a. do not need ligands and regulatory proteins as single genes would. b. do not need any modification of the proteins after they are expressed. c. allow for alterations in DNA sequence by flipping promoters around. d. allow for coordinated gene expression of related genes on one mRNA controlled by one promoter. e. allow the bacteria to use a wide variety of carbon sources.
Answer:
d. allow for coordinated gene expression of related genes on one mRNA controlled by one promoter.
Explanation:
An operon is a group of functionally-related genes that share the same promoter region and the same operator which interacts with specific repressors or activators, and they are transcribed as a unit. This transcriptional unit (operon) is present in prokaryotic organisms (i.e., bacteria and archaea) but absent in eukaryotes. In an operon, each structural gene is known as a cistron, and they are transcribed together as a polycistronic primary messenger RNA (mRNA).

The user needs to drag the slider bar in an upwards direction in order to completely melt away a body layer when in the dissection study area.
True or False
Answer:
False
Explanation:
During the dissection study the body is kept in laying position so that the scientist can easily perform experiments. The body is kept in laying position not in upward position. The body in upward position will have gravitational effect on the fluids and the body layer will not melt.

You have the following consumable items that you do not want spoiled by the action of microorganisms, but you have space in your refrigerator for only one. You have already opened each and consumed some. Which one of these is most likely to spoil fastest and should therefore be placed in the fridge?
A. Bread Flavored syrup (contains water, high sugar concentration, flavors, e.g., used to flavor coffee and drinks)
B. Apple juice 80 proof liquor (contains water, 40% ethanol, flavors)
C. Mineral water (contains water, minerals)
Answer:
Bread Flavored syrup (contains water, high sugar concentration, flavors, e.g., used to flavor coffee and drinks)
Explanation:
Food spoilage refers to a situation in which food is no longer fit for consumption due to the action of certain microorganisms on the food. Hence, microorganisms cause the spoilage of food and beverages.
The rate of action of microorganisms on different beverages depends mostly on the content of the beverages.
Yeasts are often responsible for the spoilage of beverages with high sugar content and these tend to spoil faster than other beverages.

A scientist is researching two different traits in an insect: body texture and color. Smooth body (B) is dominant to bumpy body (b), and gray (G) is dominant to white (g). A BbGg and a bbgg insect mate and produce the following 480 offspring: Phenotype Number of Offspring Smooth, gray 119 Bumpy, white 117 Smooth, white 123 Bumpy, gray 121 What type of inheritance is displayed from these offspring
Answer:
Independent assortment
Explanation:
The type of inheritance displayed by the offspring is a simple independent assortment inheritance according to Mendelian law.
The result of crossing BbGg and bbgg is as follows (see the attached image)
4 BbGg smooth and gray
4 Bbgg smooth and white
4 bbGg bumpy and gray
4 bbgg bumpy and white
The phenotype ratio from the cross is 1:1:1:1 as far as the independent assortment is concerned.
Now, looking at the population of each phenotype from the cross
Smooth, gray 119
Smooth, white 123
Bumpy, gray 121
Bumpy, white 117
119:123:121:117 is approximately equal to 1:1:1:1.
Hence, the cross agrees with Mendel's law of independent assortment of genes.
What would you expect to happen to a plant as temperature and precipatiom increases? Write your claim and evidence!!
Answer:
Both have great effect on plant when increases from a certain limit.
Explanation:
When the temperature falls in the optimum range it has a good effect on plants growth because the rate of photosynthesis is maximum. Precipitation also has a great effect because it provides water that is necessary for the plants. If the temperature increases from a certain limit, it burns plant body and decreases photosynthesis whereas if precipitation increases it causes flood condition which kills the plant due to removal from the soil.
Which of the following statements about the fossil record is correct?
A. The fossil record includes more organisms that were abundant, or lived for long periods on Earth, than it is with those that lived for short periods of time and then became extinct.
B. The fossil record is richer with organisms that are the same ones as currently common and living on Earth today.
C. A fossil of a rain forest snake would not be found in an area on Earth that is currently a desert.
D. The fossil record is richer with organisms that resemble organisms that are those alive today.
Answer:
I believe the answer would be A
Explanation:
You would have more fossils of animals that lived longer time ago than recent one bc they would be more older and more beneath the ground.And for animals to fossilize takes a long time so more older animals would be fossils
Answer:
The answer would be option A.
Explanation:
The process of fossilization is a time taking process which undergoes several stages from drying and freezing to mineralization and petrification. A fossil takes about 2.5 to 3.5 billion years to form. Both biotic and abiotic factors plays an important role in fossil formation therefore, animals that were abundant and buried frequently are more likely to fossilize than animals that lived for a short duration. Moreover, animals that are more abundant and lived for a longer period of time would be likely buried beneath the earth and would have more chances of reaching an ideal condition for fossil formation such as no decomposition which could only be achieved in an oxygen deficit environment as oxygen accelerates the process of decomposition.For more information:

Explain some of the reasons why not everyone shows traditional lateralization
Answer:
The right side of the brain may have developed more than the left side.Both sides of the brain developed equally.Explanation:
Lateralization is the term used to designate the tendency that some functions of the organism are more developed on one side of the brain. Traditional lateralization, promotes that these functions are more developed on the left side of the brain, making the right side of our body more dominant. However, it may happen that these functions develop more on the right side of the brain, or develop on both sides and in an egalitarian form, causing some people to have lateralization different from the traditional.
