Which statement best describes what happens during translation?
Answers
Answer:
B
Explanation:
The entire process is called gene expression. In translation, messenger RNA (mRNA) is decoded in a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell.
During translation, the ribosome reads the mRNA and uses the information to assemble a protein.
Translation is the second step of protein synthesis. It takes place in the ribosome, a complex structure made up of proteins and RNA. The ribosome reads the mRNA, a molecule that contains the genetic information for a protein. The mRNA is translated into a protein by a process called codon-anticodon pairing.
Codons are three-base sequences in mRNA that code for specific amino acids. Anticodons are complementary sequences in tRNA molecules that bind to specific codons. When the ribosome encounters a codon in the mRNA, it brings in the corresponding tRNA molecule. The tRNA molecule carries the amino acid that corresponds to the codon.
The amino acid is then added to the growing polypeptide chain. The ribosome continues to move down the mRNA, reading codons and adding amino acids until the entire protein is synthesized.

If 2x 2 + 13x – 7 = 0, then x could equal to which of the following?
Answers
Answer:3/13
Explanation:

x = 1/2 and x = -7
Explanation:
you need to factor
multiply 2 x -7 to get -14
then find factors of -14 that add to give you 13
14 and -1 work
now rewrite the original equation but replace 13x with 14x - 1x
so 2x^2 + 14x - 1x -7 = 0
now factor by grouping
(2x^2 + 14x) (-1x - 7) = 0
factor the greatest common factor out of each group
2x(x + 7) -1(x + 7) = 0
the factors are (2x - 1) (x + 7) = 0
set each factor equal to zero and solve both for x
2x - 1 = 0 x + 7 = 0
+1 +1 - 7 - 7
2x = 1 x = -7
÷2 ÷2

one functional center found within the medulla oblongata is a respiratory center involved in the control of the rate and depth of breathing. true or false
Answers
True. The medulla oblongata contains a respiratory center that plays a crucial role in controlling the rate and depth of breathing.
The medulla oblongata, located at the base of the brainstem, is responsible for regulating various vital functions, including breathing. Within the medulla oblongata, there is a specific region known as the respiratory center, which is involved in controlling the rate and depth of breathing.
The respiratory center consists of a network of neurons that receive sensory input from chemoreceptors, which detect changes in blood oxygen and carbon dioxide levels, as well as other respiratory-related receptors. Based on these inputs, the respiratory center adjusts the activity of the respiratory muscles, such as the diaphragm and intercostal muscles, to regulate the breathing pattern.
The respiratory center in the medulla oblongata plays a crucial role in maintaining the appropriate levels of oxygen and carbon dioxide in the body. It responds to changes in blood gas concentrations to initiate the necessary adjustments in breathing rate and depth, ensuring adequate gas exchange in the lungs and supporting overall respiratory function.

b. they curl around a support such as a fence post.
c. they have their stomata open at night and closed during the day.
d. they are extended during the day and folded at night
e. they are oriented horizontally in the dark and vertically in the light.
Answers
In nictinastic movements, the leaves roll up during the day and unroll at night.(option a)
Nictinastic movements are a type of nastic movement that is caused by the change in light intensity. In the case of nictinastic movements, the leaves roll up during the day and unroll at night. This is because the leaves contain a pigment called phytochrome, which is sensitive to light.
When the phytochrome is exposed to light, it changes shape and triggers the production of a hormone called auxin. Auxin then causes the cells on the underside of the leaf to swell, which causes the leaf to roll up. At night, when there is no light, the phytochrome reverts to its original shape and stops producing auxin. This allows the cells on the underside of the leaf to shrink, which causes the leaf to unroll.
Nictinastic movements are thought to have a number of benefits for plants. For example, rolling up the leaves at night helps to protect them from cold temperatures and from being eaten by insects. Additionally, rolling up the leaves helps to reduce the surface area of the leaf, which reduces the amount of water that is lost through transpiration.

How to make bacteria as a treatment for sewage waste
Answers
Answer: Bacteria break down organic material in wastewater and form the floc that settles and separates solids from liquids. Controlling F/M ratio–a vital component to creating a favorable environment for wastewater bacteria–can be accomplished through the use of bioremediation products. Bacteria account for 95% of the microorganisms in wastewater. They are single-celled microorganisms that are classified based on their response to oxygen.
Aerobic bacteria use oxygen, which is added mechanically, to break down wastewater contaminants, converting it into energy. Bacteria use this energy to grow and reproduce. Anaerobic bacteria obtain oxygen from their food source. As anaerobic bacteria break down sludge, they produce methane gas. This methane gas can be used as an alternative energy source, called biogas, to fuel the wastewater treatment process. Anaerobic bacteria can also be used to lower the amount of phosphorus in the effluent. Although they prefer oxygen, facultative bacteria can switch between aerobic and anaerobic forms in response to their environment.
which cell type in a leaf performs the most photosynthesis?
Answers
Answer: The cell type in a leaf that performs the most photosynthesis is the palisade mesophyll cell.
Explanation: These cells are located in the upper part of the mesophyll layer of a leaf and are packed tightly together. They contain many chloroplasts, which are the organelles responsible for photosynthesis, and have a large surface area to maximize the absorption of sunlight. The palisade mesophyll cells are also located close to the upper epidermis of the leaf, which allows them to receive the most direct sunlight. Therefore, they are the primary site of photosynthesis in most plants.

In this food chain, plankton are the primary producers, which means they convert energy from the sun into organic matter through photosynthesis. The other organisms are consumers, which means they obtain energy by consuming other organisms.
- Plankton (primary producer)
- Moral eel (primary consumer)
- Shark (secondary consumer)
- Orca (tertiary consumer)
The transfer of energy in this food chain can be described as follows:
- Plankton produce organic matter through photosynthesis, converting solar energy into chemical energy.
- Moral eels consume plankton, obtaining the energy stored in their organic matter.
- Sharks consume moral eels, obtaining the energy stored in their organic matter.
- Orcas consume sharks, obtaining the energy stored in their organic matter.
At each level, some energy is lost through metabolic processes such as respiration and digestion, and only a portion of the energy stored in the organic matter is transferred to the next level. This is known as the 10% rule, which states that only 10% of the energy from one level is transferred to the next level.

Answers
Age is an example of a nominal and discrete measure. It classifies individuals into distinct categories based on the number of years they have lived, but it does not have any inherent numerical meaning or allow for intermediate values.
Age is an example of a nominal measure. A nominal measure is a type of measurement scale that classifies data into distinct categories or groups. In the case of age, individuals are categorized into specific age groups, such as 0-18, 19-30, 31-45, and so on. These categories do not have any inherent numerical or quantitative meaning. Instead, they serve as labels to differentiate different age ranges.
Unlike a biological measure, which refers to physical characteristics of living organisms, age is not directly related to an individual's biology. It is a social construct that is used to determine the number of years a person has lived since birth. Age can be measured using a variety of units, such as years, months, or days.
Age is also a discrete measure because it takes on specific, separate values. For example, someone can be 15 years old, 25 years old, or 40 years old. There is no intermediate value between these discrete age categories.
On the other hand, age is not a continuous measure. A continuous measure is one that can take on any value within a certain range. For example, height or weight can have any value within a specific range. In the case of age, there are distinct categories and no intermediate values. You are either in one age group or another.
