Transcription is the process that must happen in order to make
Answer:
a protein
Explanation:
Transcription is one of the three main, necessary events needed for proteins to form in a cell. This happens when DNA is transcribed to mRNA. Thymine (T) is subbed in by Uracil (U), so when transcribing, A's turn into U's, not T's.
Which of the following statements best explains why evolution by natural selection is considered a theory and not a hypothesis?
Natural selection provides the outline of an explanatory theory." Biologists consider it to be a scientific fact that evolution has occurred in that modern organisms differ from past forms, and evolution is still occurring with discernible differences between organisms and their descendants.
5. A dedicated earth science student using
an aneroid barometer measures the air
pressure at the base of Slide Mountain
as 1016.0 mb. At the same time another
dedicated earth science student measures
the pressure at the top of the mountain.
Which pressure reading could be correct
at the top of Slide mountain?
(1) 1016.0 mb (3) 1025.7 mb
(2) 988.5 mb (4) 1040.0 mb 5
Answer:
(2) 988.5 mb.
Explanation:
The air pressure descends as we ascend. In other words, they are inversely proportional.
The air pressure descends as we ascend the mountain because the air molecules that are above us in high altitudes are fewer than the number of air molecules that are above us in the base of the mountain. So, the exerted pressure of the molecules on ourselves is lower in high altitudes.
Due to the reason mentioned above, we can deduce that the only correct option is option number two since the other ones show increasing or the same pressure, which is not possible as we ascend.
A barometer is an instrument that is designed for measuring the changes in air pressure.
The aneroid barometer has metal chamber as when the air pressure increases the walls of metal push in and when the pressure is low they come out. The chamber is connected by the springs and needle. If the pressure of the base of a mountain is about 1016.0 MB. The pressure of the top of the mountain is 1025.7 MBHence the option 3 is correct.

1. It is important for gametes to be haploid because: B) They fuse to form a diploid organism so there is the correct number of chromosomes.
2. When the inheritance pattern of one gene doesn't affect the inheritance pattern of another gene, this is known as: D) independent assortment.
3. A difference between phase I and phase II of meiosis is: B) Phase I results in two diploid daughter cells and phase II results in four haploid daughter cells.
4. Heredity simply refers to: B) the passing of genetic information from parents to their offspring.
5. During meiosis, sister chromatids may exchange sections of DNA leading to genetic diversity in a process called: D) crossing-over.
Gametes are also known to as sex cells and they can be defined as the reproductive cells that are found in a living organism.
It is important for gametes to be haploid cells is because when the sperm and the egg fuse to form a diploid organism, the living sex cells will have 46 chromosomes.Independent assortment refers to a biological process through which the inheritance pattern of a particular gene doesn't affect the inheritance pattern of another gene.
During meiosis, two (2) diploid daughter cells are formed in phase I while four (4) haploid daughter cells are formed in phase II.
Heredity can be defined as the transfer of genetic information (traits) from the parents of a living organism to their offspring, either through sexual reproduction or asexual reproduction.
Some examples of hereditary traits are:
Dimples.Baldness.Height.During meiosis, crossing-over makes it possible for sister chromatids to exchange sections of deoxyribonucleic acid (DNA) which leads to genetic diversity.

How does the theory of natural explanation explain the medical phenomenon of antibiotic resistance?
Answer:
Antibiotic resistance evolves naturally via natural selection through random mutation, but it could also be engineered by applying an evolutionary stress on a population. Once such a gene is generated, bacteria can then transfer the genetic information in a horizontal fashion (between individuals) by plasmid exchange.

how mutation occurs on replicated DNA molecules
Answer:
When strand slippage occurs during DNA replication, a DNA strand may loop out, resulting in the addition or deletion of a nucleotide on the newly-synthesized strand. ... But if this does not occur, a nucleotide that is added to the newly synthesized strand can become a permanent mutation.
Answer:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.

Food Availability, Places to live, and water availability are all ______ of an Ecosystem.
Answer:biotic factors
Explanation:
They are living
Food availability, places to live, and water availability are all Abiotic Factors of an Ecosystem.
What are Abiotic and Biotic components?Biotic and abiotic factors make up ecosystems in which biotic factors are living things within an ecosystem such as plants, animals and bacteria, while abiotic are non-living components such as water, soil and atmosphere.
An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, the abiotic factors are temperature, light, and water. In a marine ecosystem, the abiotic factors are salinity and ocean currents. Abiotic and biotic factors work together to form a unique ecosystem.
Biotic components are living things that have a direct or indirect effect on other organisms in the environment such as animals, and microorganisms and their waste materials.
Thus, food availability, places to live, and water availability are all Abiotic Factors of an Ecosystem.

Experiments on Osmosis are often carried out using potato
cylinders. You have been asked to find out if sweet potato or bread
fruit would be a good alternative
The osmosis process is based on solute concentration, if sweet potato or breadfruit has more amount of sucrose changing the osmolarity, hence not used for osmosis.
What is osmosis?When a potato is placed in salt water, all the water inside it, plants have a lot of water inside them, that's what gives a plant its structure travels out by osmosis because water will move from an area of less salt to more salt (more water to less water).
The cells that makeup potatoes have cell walls that function as semipermeable membranes. In comparison to the fluid inside the potato cells, the saltwater solution is hypotonic, meaning that it has more water and fewer salts.
This is because a sweet potato has more sugar than a regular potato, changing the osmolarity conditions during osmosis.
Therefore osmolarity condition is more important during osmosis, hence sweet potato or breadfruit would not be a good alternative.
