if a strand of DNA has the sequence ATGCGATCCGC, then the sequence of the MRNA molecule transcribed from it is
Answers
Answer:
DNA: ATGCGATCCGC
mRNA: UACGCUAGGCG
Explanation:
The deoxyribonucleic acid (DNA) is a double-stranded helix, where each strand is composed of four nitrogenous bases: Adenine (A), Thymine (T), Guanine (G) and Cytosine (C). The two strands are held together by hydrogen bonds and they interact in the following way: Adenine (A) always pairs with Thymine (T) through two hydrogen bonds, while Guanine (G) always pairs with Cytosine (C) through three hydrogen bonds. During transcription, a DNA strand of the double helix DNA molecule is used as template to synthesize a complementary RNA molecule, usually, a messenger RNA (mRNA) which is then used to create a protein by the process of translation. Moreover, also during transcription, Thymine (T) bases are replaced by Uracil (U) bases in the RNA molecule.

Answers
Answer:
the plasma membrane is best described as membrane found in all cells that separates the interior of the cell from the outside environment. The plasma membrane regulates the transport of materials entering and exiting the cell.
Explanation:
Structurally, the plasma membrane is best described as a selectively permeable membrane that permits specific molecules to pass in and out of the cell.
What is a Plasma membrane?A plasma membrane may be defined as a type of biological membrane that is considerably found in all plants and animal cells. The purpose of this membrane is to separate the interior surroundings of the cell from the outside environment.
According to the context of this question, the plasma membrane is a semi or selectively permeable membrane which allows the in and out movement of specific molecules within the cell. It includes molecules like water and other gaseous compounds that can pass through the cell membrane directly.
Therefore, structurally, the plasma membrane is best described as a selectively permeable membrane that permits specific molecules to pass in and out of the cell.

what are the function of protease ?Proteases are the enzymes found in all living organism like bacteria, algae, plants and animals and in some of the viruses.
They are mainly involved in the catabolism and digestion of proteins and cell signalling, involve in hydrolysis of peptide bonds and convert them to amino acids, which is then absorbed and utilised by cells.
They involve in blood coagulation process, cell division, growth, apoptosis and migration, recycling and transport across membranes.,
They participate the in activation of precursor proteins and zymogens.

If the half life of an element was 430 years and you had 2000 atoms of this element, how long would it take to undergo complete radioactive decay? What year would it be when the element finished decaying?
Answers
part a.
it would take an estimated 2984 years for the element to undergo complete radioactive decay.
How do we calculate?N = N₀ * (1/2)\(^(^t ^/^ T^)\)
N = final number of atoms remaining
N₀ = initial number of atoms
T = half-life of the element
0 = 2000 * (1/2)^(t / 430)
(1/2)^(t / 430) = 0
log₂((1/2)= log₂(0)
(t / 430) * log₂(1/2) = log₂(0)
0.01 = (1/2)^(t / 430)
log₂(0.01) = (t / 430) * log₂(1/2)
t = log₂(0.01) * 430 / log₂(1/2)

Though the brain represents less than 2 percent of your body weight, it uses 25 percent of
the oxygen you breathe and 70 percent of your glucose supply.
The brain has five basic regions:
Cerebellum - Coordinates body movement.
Brain stem - Responsible for basic life functions such as blood pressure and breathing.
Thalamus - A Grand Central relay station for incoming data from all the senses except
smell.
Hypothalamus - A regulator of hunger, thirst, sleep, sexuality, and emotions.
Cerebrum - Our gray matter, home to thought, vision, language memory, emotions. It's
divided into hemispheres. If you're right-handed, odds are the right hemisphere is where
you make sense of music, images, space, emotions. Your left hemisphere is apt to focus
on math, language, speech. In left-handed people, tasks are usually reversed.

By moving warm water & precipitation from the poles to the equator & equator toward the poles back to the tropics, ocean currents function much like a conveyer belt.
As a result, currents control the climate globally, helping to balance out the unequal distribution of solar energy that reaches the surface of the Earth. NASA has noted how sea levels will rise as the Earth warms. Warmth causes water to expand. Because warm water occupies more space in our oceans, sea levels rise as a result. Melting ice on land is another factor contributing to ocean rise. By moving warm water or precipitation from of the equator to the poles and equator toward the poles back to the tropics, ocean currents function much like a conveyor belt.

why human with heterozygous genotype will have the dominant phenotype?
Answers
A human with heterozygous genotype can have a dominant phenotype if one of the alleles complete mask the effects of the other.
Heterozygous genotype involves two different alleles, unlike homzygous genotypes in which the alleles are the same.When the two alleles of an heterozygous genotype exert equal effects on one another, they are said to be codominant.When one of the alleles of an heterozygous genotype incompletely exert its effects on the other allele, it is said to be incomplete dominance.When one of the alleles complete dominates and masks the effects of the other allele, it is said to be dominant.Hence, a dominant allele will always produce a dominant phenotype even if the genotype of the organism is heterozygous.

How rapid changes in weather conditions occur. Arrow labeled Direction of frontal movement points right toward Cold front map symbol. Arrow labeled Rising warm air in front of cold front points from cold front to sky. Also labeled are: Development of clouds because of upward movement of warm air, and Advancing cold air behind cold front.
Based on the arrows, what does the image represent?
Air masses are barely moving.
Air masses are colliding with each other.
Jet streams are forming in the upper atmosphere.
Weather conditions are remaining steady and unchanged.
Answers
The image represents air masses colliding with each other, leading to rapid changes in weather conditions.
The image represents the process of rapid changes in weather conditions occurring. The arrows in the image indicate various elements and phenomena related to these changes.
At the top, the final answer is that the image represents "Air masses are colliding with each other."
1. The arrow labeled "Direction of frontal movement" points right toward the "Cold front" map symbol. This indicates the movement of a cold front.
2. The arrow labeled "Rising warm air in front of cold front" points from the cold front upward into the sky. This signifies the upward movement of warm air.
3. The image also shows the development of clouds due to the upward movement of warm air. This indicates the presence of moisture in the atmosphere.
4. Finally, the image depicts advancing cold air behind the cold front, indicated by an arrow. This cold air is moving in the direction of the warm air.
Putting all these elements together, we can conclude that the image represents air masses colliding with each other. The cold front is advancing and pushing against the warm air, leading to the formation of clouds and changes in weather conditions. This collision between air masses often results in rapid changes in weather patterns, such as storms, rain, or temperature fluctuations.

Answers
The formation of sucrose from the reaction of a glucose molecule with a fructose molecule is Molecule of fructose Glucose + Fructose ------> Molecule of sucrose
What happens when glucose and fructose react?Sugars like fructose and glucose can combine to form sucrose. A sugar that has one unit of fructose and one unit of glucose, sucrose is a disaccharide. A condensation reaction occurs when two molecules are joined together and a water molecule is released.
A glycosidic bond, which is a covalent bond between two monosaccharides, is created by this reaction between the two molecules. The following is the response:
The enzyme sucrase is responsible for initiating the glucose, fructose, sucrose, and water reaction. It helps break down sucrose for digestion and is found in the small intestine. A dehydration synthesis reaction, in which the two molecules join together and release water, is demonstrated by this reaction.
It is also an illustration of a condensation reaction, in which two molecules join together to release a small molecule like water.
The digestion of sucrose and other disaccharides like lactose and maltose is dependent on the fructose-glucose reaction. Additionally, the reaction has a significant impact on the energy production and carbohydrate metabolism.
