All of the following are reasons for regulation of gene expression EXCEPT -
Answer:
There are three broad levels of regulating gene expression:
transcriptional control (whether and how much a gene is transcribed into mRNA)
translational control (whether and how much an mRNA is translated into protein)
Explanation:
The first method of controlling transcription is by regulating the quantity of mRNA that can be generated from a given gene, hence option C is correct.
What is gene expression?The level of regulation involves post-transcriptional processes that manage how mRNA is translated into proteins, repair of damaged cells are not controlled by gene expression.
The expression of an animal's genes ultimately determines its phenotype, which is influenced by environmental variables like as nutrition, temperature, oxygen levels, light cycles, and the presence of mutagens.
Therefore, despite the fact that every cell type in your body has the exact same DNA, gene regulation allows for each cell type to have a unique collection of activated genes, hence option C is correct.

24. Why is everything in our solar system attracted to the sun? *
a. smallest gravitational attraction in the solar system
b. largest gravitational attraction in the solar system
c. it is equal distance to all the planets
O d. it orbits around the planets
Answer:
B. Largest gravitational attraction
Explanation:
Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.
I beleive it's B because it would have to be a strong gravitational pull to keep everything balanced correctly.

What agent of deposition is this? Gravity,wind, waves, running water or glaciers.
Answer:
The answer is "running water or glaciers".
Explanation:
The material is placed if erosion agents can longer carry sand. For instance, if another fluvial water slows at the river mouth, soils become rivers. The four key reasons for accumulation was its movement of reinforced the fact material surface, air, ice, liquid, and inertia, accumulated at the loss with enough kinetic energy throughout the fluid to create substrate layers. Accumulation can also apply to natural head moves or processes create of soil.

The pigment plants have that they use for photosynthesis is called _________.
Answer:
chlorophyll
Explanation:
The mechanism by which light energy can be transformed into chemical energy by synthesis of organic compounds is chlorophyll, a member of the most significant pigment class involved in photosynthesis. In nearly all photosynthetic species, e.g. green plants, cyanobacteria and algae, the use of chlorophyll is identified. It consumes light energy and is then used for the conversion to carbohydrates of carbon dioxide.

If capital D = the allele for dimples, and lowercase d = the allele for NO dimples, what percentage of the offspring will show having dimples, with parents having genotype Dd (capital D and lowercase d) and genotype dd (two lowercase ds)?
If D is the allele for dimples and d is the allele for no dimples, a percentage of offspring with genotypes Dd is 50% and 50% dd will be produced with no dimples.
How will the allele for dimple express?The dimple appears when the D is present, which occurs in both the purebred dominant case (DD) and the heterozygous case (Dd), so when the dd is present, no dimple is seen. The dimple is dominant over the no dimple, so when the heterozygote Dd crosses with the purebred dd then 50% will have dimples and the other 50% won't, as the heterozygotes will produce both D and d types of alleles that will combine with d to make two types of offspring.
Hence, if D is the allele for dimples and d is the allele for no dimples, a 50% percentage of offspring with genotypes Dd and 50% of offsprings with genotype dd will have no dimples.

Emily’s friend Mark recently learned that he was adopted; although his parents tried to keep it a secret for as long as possible, he realized that he could not be their biological son because he has brown eyes, a dominant trait, while they both have blue eyes, a recessive trait.
Is Mark correct in assuming he must be adopted because of his difference in eye colour?
Answer:
Explanation:
Two blue eyed parents have a brown eyed baby Although it is uncommon, parents with blue eyes can have children with brown eyes. The inheritance of eye color is more complex than originally suspected because multiple genes are involved.

Answer:
The correct answer is - Four phases of Mitosis:
Prophase, Metaphase, Anaphase, and Telophase.
P- Prophase
M- Metaphase
A- Anaphase
T- Telophase
Explanation:
PMAT is an acronym that is used for a transporter protein Plasma membrane monoamine transporter as well as the four stages of the mitosis cell cycle. On the basis of the reference given in the form of an image, it is most like the four stages of mitosis are : Prophase, Metaphase, Anaphase, and Telophase.
Prophase is the first stage of mitosis and followed by the metaphase, anaphase, and ends with telophase. Telophase is followed by cytokinesis.

What type of energy is made during respiration
Answer:
During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
Answer:
The source of the energy required to regenerate ATP is the chemical energy stored in food (glucose) The cellular process of releasing energy from food through a series of enzyme-controlled reactions is called respiration . Some of the energy released is used to produce ATP. So I believe it would be chemical energy

the human heart starts beating around_____days of embryonic development(. )
a) 22
b) 21
c) 23
d) 24
Answer:
a) 22
Explanation:
Cardiogenesis which is the formation of the heart begins by day 21. The heart begins to form as paired tubes. By days 22 - 23 of embryonic development, the heart begins to beat. This represents the formation of the first vital organ of the body and it also causes the formation of left-right asymmetry of the body.
The days are counted from the day of the last menstrual period.
