which of the following statements best describes how the traits of an organism are determined by the DNA in their cells?
Answer:
C. DNA codes for proteins which allow an organism to grow and function
Explanation:
Deoxyribonucleic acid, commonly known as DNA is the genetic material in living organisms. The DNA stores genetic information, which encodes the formation of useful products (proteins) necessary for the growth and development of that particular organisms. The information in DNA is decoded by a process called GENE EXPRESSION, which encompasses transcription and translation.
Transcription is the process that synthesizes RNA from DNA molecule, while translation synthesizes PROTEIN from the mRNA. Hence, the order which is called CENTRAL DOGMA OF BIOLOGY is as follows: DNA → RNA → PROTEIN.
Therefore, DNA codes for proteins which allow an organism to grow and function best describes how the traits of an organism are determined by the DNA in their cells.
Doctors determined that babies born at 37 weeks have an increased risk of health problems due to insufficient development. Premature babies may need medical attention to help with respiration, until their lungs fully develop. They may also need to have extra protection from germs, because their immune systems may not be functioning. I would also expect that premature babies weigh less than full-term babies.

Explanation:
What would be likely to happen if a large excess amount of phosphorylated Rb is injected into cells during the G1 phase
Answer:
it would block the S-phase entry and cell growth
Explanation:
The Rb protein is known to be a major G1 checkpoint. Rb is also known to be a tumor suppressor since this protein limits cell proliferation by preventing entry into the S-phase entry and cell growth. When the cell is ready to enter the division phase, Rb is phosphorylated and thus inactivated. In HL-60 cells, it has been shown that the levels of phosphorylated Rb protein increase with progression from G1 to S and to G2/M. This protein acts as a negative regulator that blocks the activity of the E2F transcription factor.

Which two terms describe this type of bone fracture?
simple, incomplete
compound, complete
simple, complete
compound, incomplete
The correct answer is Compound, complete
Explanation:
Bone fractures occur as bones (hard tissue that is part of the skeleton) break, which can be caused by traumatic incidents, certain diseases, among others. Moreover, fractures are classified into different categories such as compound/simple, complete/ incomplete depending on the characteristics of the bone fracture.
In the case of compound fracture, this occurs if the bone is exposed. This means the bone breaks and then displaces causing an open wound. This occurs in the bone fracture from the image because the bone has moved to the left and break the skin, muscle, and other tissue of the area. On the other hand, a fracture is complete is the fragments of the bone are completely separated, which occurs in the image because the bone has been completely divided into two sections.

_____________________________________PEA PLANT:Pea plant has purple color flowers dominant over white color flowers.
Purple flower allele is P
White Flower allele is p
We would get White flower pea plant only when the recessive allele is in DOMINANT condition
_____________________________________CONDITIONS:Hom.ozygous Dominant Alleles: PP (Purple Flower)
Heter.ozygous Dominant Alleles: Pp Purple Flower)
Hom.ozygous Recessive Alleles: pp (White Flower)
_____________________________________CROSS:Whenever we cross Hom.ozygous Dominant(PP) with Heterozygous dominant (Pp), we get all the flowers PHENOTIPICALLY(physical appearance) Purple flower, Because as you can see in the picture,
The P1 is PP
The P2 is Pp
When we cross them,
It has 4 offsprings,
PP purple flower
PP purple flower
Pp Purple flower
Pp Purple flower
Thus the answer is 0% as there is no white flower present
_____________________________________Best Regards,'Borz'Explain how a concentration gradient, a membrane protein, and hydrogen ions work together to provide a mitochondrion with the energy needed to join small molecules together?
During the electron transport, chan energy stored in electrons is used to pump hydrogen protons from the mitochondrial matrix to the intermembrane space. The numbers of protons increase this creates a chemical gradient(because there is a higher concentration of ions) and an electrical gradient(because the intermembrane space becomes more positive than the matrix because of the protons-H⁺). Those protons need to flow towards the matrix for equilibrium to occur. As we know the inside membrane of the mitochondria has a reduced permeability. The main place where protons can diffuse is the ATP-synthase(a protein that turns ADP and inorganic phosphate into ATP). When protons pass through they release the energy necessary for this reaction to occur(ADP+H₃PO₄-->ATP+H₂O)
A concentration gradient, a membrane protein, and hydrogen ions work together to provide a mitochondria with the energy needed to join small molecules together through ATP. The H+ ions are pumped across by membrane “pump proteins” into a space bounded by memb ranes that contain numerous amounts of hydrogen ions. Then, electrons are passed from o ne membrane-bound enzyme to another, which causes some energy to get lost during eac h transfer. This “lost energy” allows the pumping of hydrogen ions against the concentratio n gradient. After all the steps are taken, the mitochondrion will be provided with the energy needed to join small molecules together.

Enzymes can accelerate reactions by:___________.
A) binding a substrate or substrates.
B) promoting the removal or addition of protons.
C) correctly positioning a metal ion for catalysis.
D) lowering the energy for activation.
E) all of the above.
Answer:
D) lowering the energy for activation.
Explanation:
Just like chemical catalysts that accelerate the rate of chemical reactions, enzymes are biological catalysts that accelerate the rate of biochemical reactions.
Majorly, a catalyst works by lowering the activation energy required for a specific reaction. The lower the activation energy for a reaction, the faster the rate of that particular reaction.
Hence, an enzyme accelerates the rate of reaction by lowering activation energy of the reaction.

An eagle is a predator for squirrels. A new law stops humans from hunting
eagles, and the eagle population increases. What will happen to the squirrel
population?
A. The carrying capacity of the ecosystem will increase.
B. The squirrel population will increase.
C. The ecosystem will reach Hardy-Weinberg equilibrium.
D. The squirrel birthrate will decrease.
Answer:
Imma say D
Explanation:
As eagle feeds on squirrels, an increase in the number of eagles, will obviously lead to a decrease in the number of squirrels.
An eagle is a predator for squirrels, a new law stops humans from hunting eagles, and the eagle population increases, so the most likely outcome is that the squirrel population will decrease due to an increase in eagle predation, which is option D.
What is a predator-prey relationship?Eagles are predators of squirrels, and an increase in the eagle population will likely lead to an increase in predation on squirrels. This could result in a decrease in the squirrel population. However, it's worth noting that the relationship between predator and prey populations is complex, and the effect of an increase in the predator population on the prey population will depend on a variety of factors. While an increase in the eagle population due to new laws that prohibit hunting them may have positive implications for their conservation, it could potentially have negative consequences for the squirrel population.
Hence, the most likely outcome is that the squirrel population will decrease due to an increase in eagle predation, which is option D.

State, in terms of the number of subatomic particles, one similarity and one difference between the atoms of these isotopes of element X.
Answer:
The atomic number is determined by the number of protons in the atom.
Neutrons can vary the mass of atoms of the same element; atoms of the same element with the different atomic masses are called isotopes.
Electrons do not contribute a meaningful amount of mass to an atom, and only vary the charge of the atom. A charge atom is an ion.

You are interested in tracking a particular trait. To begin your studies you do a dihybrid self cross. What percentage of the offspring will be dihybrids themselves
Answer:
4/16 (i.e. 25%)
Explanation:
A dihybrid cross is a cross between two organisms/lines/genes that are hybrids (i.e., heterozygous) for two different traits. In a standard dihybrid cross, there is a relation of complete dominance for both loci, i.e., there are two alleles that are completely dominant and thus mask the effects of the corresponding recessive traits. In a dihybrid cross involving two different genes that assort independently into gametes during meiosis, with dominant alleles "A" and "B" and recessive alleles "a" and "b", respectively, the expected phenotypic ratio will be 9:3:3:1 (ie. 9/16 A_B_, 3/16 A_bb, 3/16 aaB_ and 1/16 aabb), while the expected genotypic ratio of double heterozygous "AaBb" individuals will be 4/16, i.e. 25%.
Representation:
P generation >> AaBb (father) X AaBb (mother)
Gametes (for both parents) >> 1/4 AB; 1/4 Ab; 1/4 aB; 1/4 ab
F1 generation >> 1/16 AABB; 2/16 AABb; 2/16 AaBB; 4/16 AaBb; 1/16 AAbb; 2/16 Aabb; 1/16 aaBB; 2/16 aaBb; 1/16 aabb
For a quantitative trait explained by four loci in an additive fashion, if the four locus genotype AaBbCcDd corresponds to a phenotypic value of 32, and the four locus genotype AABBCCdd corresponds to a phenotypic value of 48, then what is the phenotypic value corresponding to the four locus genotype AABbcCDD?
Answer:
48
Explanation:
In genetics, additive effects represent a mode of quantitative inheritance that occurs when the combined effects of alleles (i.e., the variants of a gene that lead to differential expression of a phenotypic trait) at two or more loci are equal to the sum of their individual effects, contributing thus to the final phenotype. Therefore, the additive variance can be explained by the sum of the individual effects of identified loci/genes that have an additive effect on this quantitative trait. In this case, each gene shows an additive effect (equal to 8 for each dominant allele), thereby the phenotypic value corresponding to the genotype AABbCcDD will be equal to 48 (i.e., 16 + 8 + 8 + 16 = 48).

ATP is to your cells as ______ is to a car
Answer:
Gas to a car
Explanation:
The ATP function in the cell is equal to the gas or fuel function in the car, as the ATP gives energy to the cell for different functions like the fuel gives energy to the car to move from one place to another.
What is the function of the ATP?
ATP is produced in the cell from the food that living organisms, such as animals and plants, consume and use to produce ATP. There are different reactions that together make ATP, such as glycolysis, the Krebs cycle, and the electron transport chain, and with the help of ATP synthase, ATP is made. It performs a variety of cellular functions, including protein synthesis, food digestion, message transmission from one cell to another, and so on.
Hence, the ATP function in the cell is equal to the gas or fuel function in the car, as the ATP gives energy to the cell for different functions.
