The mRNA strand is complementary to the DNA template strand; however, uracil instead of thymine is paired with adenine.
How, explain briefly?Protein synthesis which encompasses how gene is used to synthesize proteins consists of two processes namely; transcription and translation.
- Transcription is the process whereby the sequence of a DNA template is used to synthesize a mRNA strand. The mRNA sequence is synthesized using the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine base (A) will always hydrogen pair with Thymine (T) while Guanine (G) will always pair with Cytosine (C).
Thus,This means that the mRNA strand produced is complementary to the DNA template strand that was transcribed. However, Uracil base (U) replaces thymine (T) in the mRNA molecule because Thymine is not found in RNA. Hence, Uracil instead of Thymine pairs with Adenine in the mRNA.

3. What drives the ATP synthase reactions that produce ATP?
A the redox reaction that changes NADH to NAD*
B the formation of water at the end of the electron transport chain
C the energized electrons from the electron transport chain
D the hydrogen ion concentration gradient across the membrane
Answer:
D the hydrogen ion concentration gradient across the membrane
Explanation:
gradient created by this drives hydrogen back through the membrane, through ATP synthase
Hydrogen ions flow down a concentration gradient from the thylakoid space to the stroma through ATP synthase, releasing energy that can be used to produce ATP from ADP + Pi
ATP synthase is a mitochondrial enzyme localized in the inner membrane, where it catalyzes the synthesis of ATP from ADP and phosphate, driven by a flux of protons across a gradient generated by electron transfer from the proton chemically positive to the negative side.
At the electron transport chain, hydrogen is built up on one side of the electron transport chain and the electrons which are their way down the chain are building up on the other side. The electrons and hydrogen are attracted to each other due to their charges. These for the hydrogen flows though the gradient in the membrane to reach the elections. Once the hydrogens pass though this gradient it produces the ATP from the hydrogen
Once the hydrogens pass though this gradient it produces the ATP from the hydrogen “turning” the protein. At the end the oxygen is placed at the bottom of the electron transport chain to accept the hydrogen which makes water

What is a chromosome?
Answer:
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Explanation:
Chromosomes are thread-like structures in which DNA is tightly packaged within the nucleus. DNA is coiled around proteins called histones, which provide the structural support. Chromosomes help ensure that DNA is replicated and distributed appropriately during cell division.

Explain how blood type contributes to your identity.
Answer:
Each biological parent gives one of their two ABO alleles to their child. For example, a father who has blood type AB has the genotype AB, so he can give either an A or a B allele to a child of his. If the mother has blood type O, her genotype must be OO, and she can only give an O allele to a child.

Which of the following is a severe weather consequence that results in crop reduction from lack of precipitation? (4 points)
Drought
Tornadoes
Mold
Floods
The consequence of lack of precipitation is drought.
What is drought?Drought refers to the lack of or inadequate precipitation in an area.
When there is drought, crops suffer from inadequate water. Inadequate water will impair important growth and reproductive processes in plants, resulting in crop failure.
Without adequate water, plants cannot photosynthesize, divide mitotically or meiotically, and the required nutrients for growth become unavailable in the soil.

Changes in environmental conditions always result in new ecosystems and loss of biodiversity characterized by an increase in the number of some species, the evolution of new species, and the extinction of some species.
Changes to the environmental conditions can indeed result in new ecosystems and a change in the species equilibrium.
Ecosystem disruptionThe abiotic conditions of an ecosystem determine the kind of species that will inhabit the ecosystem
A change to the abiotic or environmental conditions will likely result in a new ecosystem entirely. Organisms that are able to adapt to the changes will gradually fade off the ecosystem while those that are able to withstand the changes will proliferate and dominate the populations of organisms in the ecosystem.
