Mistakes are sometimes made in duplicating or transmitting genetic information. These mistakes are called
Answer:
Mutation
Explanation:
Mutation is any alteration or change in the genetic sequence of a gene caused by mutagens (substances) or mistakes during replication of genetic sequences.
A mutation occurs in the gene from time to time, although, the cell has protocols in place to put them under control if they occur. However, when DNA or a gene is being copied and transferred to offsprings, there is bound for mistakes called MUTATION to occur.
Which of the following is true about CO_2CO
2
?
A
It does not have much effect on the climate.
B
It is a greenhouse gas.
C
Very little CO_2CO
2
is being emitted now.
D
If we cut CO_2CO
2
emissions by half, the temperature will stop rising.
Answer:
B.
Explanation:
It has a huge impact on the environment
It is being emitted in large amounts
And if we cut our carbon emissions in half it would delay the risk of raising the global temperature of 1.5 degrees Celsius but half of it would still pumped into the atmosphere along with the carbon dioxide already in the atmosphere.
But it is a greenhouse gas because it helps trap the heat remaining in Earth's atmosphere which is why the Earth is warming.
CO2 is a greenhouse gas.
what are greenhouse gases?
Greenhouse gases are gases in the atmosphere that affect the energy balance of the planet. The greenhouse effect is caused by them. Carbon dioxide (CO2), methane, and nitrous oxide, the most well-known greenhouse gases, can all be present in low concentrations in the environment.
The greenhouse gases in the atmosphere trap heat and warm the earth.
Carbon dioxide, methane, nitrous oxide, and water vapor (all of which exist naturally) are the principal greenhouse gases, as are fluorinated gases (which are synthetic).
Carbon dioxide (CO2) is released into the atmosphere as a result of the combustion of fossil fuels (coal, natural gas, and oil), solid waste, trees, and other biological materials, as well as chemical processes (e.g., manufacture of cement). As part of the biological carbon cycle, carbon dioxide is absorbed by plants and released from the atmosphere.
hence, CO2 is a greenhouse gas.

If two hybrid tall pea plants are crossed what is the probability that the offspring will have the tall phenotype?
Answer:
There is a high probability that the Pea plant will have a High phenotype!
Explanation:
Because both "parent plants" are tall, this will cause the offspring to also be tall, this will be because it in it's genes or in other words DNA too be strong.

The F1 mother of these progeny (F2) resulted from a cross between two flies from true breeding lines (P generation). What are the genotypes of these two lines
The question is incomplete. The complete question is :
In fruit flies, the recessive pr and cn mutations cause brown and bright-red eyes, respectively (wild-type flies have brick-red eyes). The double mutant pr cn combination has orange eyes. A female who has wild-type eyes is crossed to an orange-eyed male. Their progeny have the following distribution of eye colors:
wild-type8

The F1 mother of these progeny (F2) resulted from a cross between two flies from true breeding lines (P generation). What are the genotypes of these two lines ?
Answer:
prprcn+cn+ and pr+pr+cncn
Explanation:
Progeny is the offspring or descendants of any animal, plant, human or a species.
In the context, it is given that the cn mutation and recessive pr in the fruit flies makes brown and bright red color eyes. And the double mutant of pr and cn combination makes orange eyes. An oragne eye males is crossed with a female having a wild type eyes. Now for this, the F1 mother of the progeny F2 which results from the cross of two flies, the genotypes is " prprcn+cn+ and pr+pr+cncn. "

What are chromosomes? How are they different between prokaryotes and eukaryotes?
Answer: A chromosome is a long DNA molecule with part or all of the genetic material of an organism. The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not
Explanation:
Chromosomes are long thread of DNA molecule. Prokaryotes have one chromosomes while eukaryotes have many.
Chromosome:
It is a long thread of DNA molecule as a part of genetic material of all living organisms.
In prokaryotes, DNA is not very much compacted.Only one chromosome is usually scene in prokaryotes.In Eukaryotes, Chromosome are very compacted and form an special structure.Multiple chromosomes are found in Eukaryotes.
Therefore, chromosomes are long thread of DNA molecule. Prokaryotes have one chromosomes while eukaryotes have many.

What is the medical term for the process or procedure that destroys or inhibits disease-causing microorganisms to prevent infection:
Answer: Sterilization.
Explanation:
Sterilization is the process that kills, or deactivates all forms of life so then a product is considered free of viable microorganisms. This process must be designed, validated and carried out to ensure that it is capable of eliminating the microbial load of the product.
Since sterility cannot be demonstrated without causing the complete destruction of the products, sterility is considered when the probability of a product being contaminated is acceptably remote. A critical product is considered sterile when the probability of a microorganism being present in an active or latent form is equal to or less than 1 in 1,000,000 (sterility safety factor 10^-6).
Agents that kill microorganisms are called microbicides or more commonly called "germicides". If the agent kills bacteria, it is called a bactericide. And if it kills fungi, then it is called a fungicide. It is important to consider than after an exposure of the sterilized object to the air or its surroundings, it will have become contaminated again with microorganisms.
Examples of sterilization include physical methods and chemical methods. Physical methods include:
Wet heat (in steam autoclave) Dry heat (in sterilization oven) Radiation (gamma radiatio, electron beam, X-ray, ultraviolet, microwave, white light)Chemical methods include a variety of chemicals in liquid and vapor form, for example:

Answer:
Subducts
Explanation:
According to Merriam Webster and TheFreeDictionary, the definition of subduct is "A geologic process in which one edge of one crustal plate is forced below the edge of another." Since this sentence indicates that an oceanic plate sinks under the continental plate, therefore I believe the fill-in-the-blank word would be 'subducts' or a similar word.

During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Mitosis itself consists of five active steps, or phases: prophase, prometaphase, metaphase, anaphase, and telophase.
The pathophysiology of osteomalacia involves a. collagen breakdown in the bone matrix. b. inadequate mineralization in the osteoid. c. crowding of cells in the osteoid. d. increased osteoclast activity.
Answer:
The correct answer is - b. inadequate mineralization in the osteoid.
Explanation:
Osteomalacia is a condition where the bones become weak and soft, this bone softening is occurred due to mainly vitamin D deficiency that also causes rickets. It leads to insufficient or inadequate mineralization in the osteoid.
This conditing when takes place in kids and young adult leads to curve or bowing during the growth period. In this case, bones are very prone or easily fractured.
