Answer:
The correct answer is - facilitated diffusion.
Explanation:
Facilitated diffusion is a form of facilitated transport of molecules such as amino acid, glucose, and others through the plasma membrane involving the passive or indirect movement of molecules along their concentration gradient, which is led by the presence of another molecule normally a pore or channel made up of integral protein.
Facilitated diffusion depends on several factors such as the size of molecules, type of molecules, similarity of molecules to extracellular matrix or fluid that slow or fast the diffusion process.
Thus, the correct answer is - facilitated diffusion.

If the Hemoccult test result is negative, no further testing is done. If the Hemoccult test result is positive, the individual will have a second stool sample tested with the Hemoccult II test. If this second sample also tests positive for blood, the individual will be referred for more extensive evaluation. What is the effect on net sensitivity and net specificity of this method of screening
Answer:
Hemoccult test sensitivity is 89.3% and specificity is 92.7%
Explanation:
Hemoccult test is a test that is carried out in order to find out the presence of occult blood in your stool. This method is used to detect colorectal cancer in your body. Blue color of the blood indicate that the test is positive while the green color represents that the test is negative. Test sensitivity is the ability of a test which identify the person who is affected with the disease i. e. true positive, whereas test specificity is the ability of the test to correctly identify the patient without the disease. The value of sensitivity of the Hemoccult test is 89.3% the specificity is 92.7%, and the positive predictive value is 2.5%.

2)Masses of matter collide, masses of matter form around dust grain, and atoms and molecules are added to dust grain.
3)Atoms and molecules are added to dust grain, masses of matter form around dust grain, and masses of matter collide.
4)Masses of matter collide, atoms and molecules are added to dust grain, and masses of matter form around dust grain.
Answer:
The correct option is 3. Atoms and molecules are added to dust grain, masses of matter form around dust grain, and masses of matter collide.
Explanation:
Two theories explain how planets get formed. One of them is The gravitational instability, and the other one is the Planetesimal Hypothesis.
The planetesimal hypothesis says that a planet formation is a process in which dust particles and gas collide and get stick together in a process known as coagulation. This makes place to grains production. These grains enhance their sizes up to a point in which they form bodies big enough to be called planetesimals. When planetesimals are formed, they start a gravitative interaction with other planetesimals of different sizes, and by collision, they form bigger planetesimals that accrete the smaller ones and end up forming a proto-planet. Planets and giant planets get formed by accretion of solid planetesimals. The term accretion refers to the solids agglomeration to form bigger objects, such as planets.

The speckled chicken on the right results from a cross between a black and white chicken. Explain what type of inheritance this would be, and draw a punnett square to show how this would happen.
Answer:
- Codominance
- 100% speckled chicken
Explanation:
This gene inheritance is called codominance, where both alleles can be expressed. In these cases, heterozygote individuals instead of showing an intermediate phenotype, express both alleles. Their phenotype is an additive expression of their parents' genes.
When two individuals, homozygous for a certain trait, are crossed they produce heterozygous individuals that express both alleles equally.
A typical example of codominance is the case of speckled chicken, the product of the cross of a black individual with a white individual. Black chickens (BB) only have this gene for feather color, while white chickens (WW) only have the gene for white feathers. When they cross, their progeny will have both genes (BW), and both of them will be expressed as speckled feathers.
Cross:
Parental) BB x WW
Black White
Gametes) B B W W
Punnet square) B B

6. increases vascular flow
7. growth in thickness
10. lateral meristem
11. vascular cambium
Both:
8. occurs in plants that live many years
Explanation:
Plant primary growth starts with successive cell division cycles in undifferentiated cells that form the shoot apical meristem, thereby lengthening roots and stems. The meristems represent a type of tissue involved both in primary and secondary growth. Herbaceous plants have only primary growth and grow in length.
Secondary growth is caused by the growth of the vascular cambium (cambia) and lateral meristems. It is characterized by an increase in thickness of stems and roots. Vascular plants (i.e., plants with a xylem and phloem system) have secondary growth.
In woody plants, the primary and the secondary growth patterns occur across years, and thus they can increase their length (primary tissue growth) and diameter (secondary tissue growth).

In sheep, coat color is influenced by two genes. Gene A influences pigment production, while gene B produces black or brown pigment. If two heterozygous white sheep resulted in 12 white sheep, 3 black sheep, and 1 brown sheep, which genotype(s) of the white sheep explain this data?
Answer:
Dominant epistasis best explains this ratio of 12:3:1.
Genotype(s) AABB, AABb, AAbb, AaBB, AaBb and Aabb explain white phenotype of sheep.
Explanation:
It is a clear case of dominant epistasis which is in turn a result of gene interaction. In dominant epistasis, dominant allele of one gene masks the expression of another gene which is present at different locus.
When we will cross two heterozygous sheep AaBb x AaBb, progeny with following genotypes will be produced:
1- AABB - White
2- AABb - White
1- AAbb - White
2- AaBB - White
4- AaBb - White
2- Aabb - White
1- aaBB - Black
2- aaBb - Black
1- aabb - brown
In this case, dominant 'allele A' of gene A will mask the expression of gene B. This is the reason why genotype AABB, AABb, AAbb, AaBB, AaBb and Aabb are producing white phenotype. So in total, 12 sheep will produce white phenotype.
But when dominant 'allele A' is absent, then only gene B will be able to express if it is present in dominant form. This is the reason why aaBB and aaBb are producing black phenotype because here dominant allele A is absent and recessive allele a will not be able to mask the expression of gene B because gene B has dominant allele here i.e. BB and Bb. So 3 sheep will produce black phenotype.
But when when dominant 'allele A' is absent and gene B is in recessive form i.e. bb then a third phenotype will be produced which is brown. This is the reason why aabb will produce brown color. So only 1 sheep will produce brown phenotype.

Identify the correct statements about transcription(Tnx) and (Tnl) translation in prokaryotes and eukaryotes.
A. Prokaryotes conduct Tnx and Tnl together in the same cellular compartment.
B. Eukaryotes do Tnx in the nucleus and Tnl in the cytoplasm.
C. Tnx and Tnl occur together in the cytoplasm of Prokaryotes and Eukaryotes.
D. Tnx and Tnl both occur in the nucleus in eukaryotes and prokaryotes.
Answer:
A and B
Explanation:
The correct statements about transcription and translation would be that prokaryotes conduct transcription and translation together in the same cellular compartment and eukaryotes do transcription in the nucleus and translation in the cytoplasm.
Prokaryotes generally lack a nucleus and other membrane-bound organelles and as such, their genetic materials lie freely within the cytoplasm. Hence, transcription and translation take place within the same cellular compartment, which is the cytoplasm.
Eukaryotes, however, have a nucleus and other membrane-bound organelles such as mitochondrion. Their genetic materials lie majorly in the nucleus. Hence, transcription takes place within the nucleus. Thereafter, the transcribed mRNA is transported to the cytoplasm where they get attached to ribosome and tRNA and translated into proteins.
The correct options are A and B.
"Assume that a man and a woman are phenotypically normal, but the woman is heterozygous for a pericentric inversion on chromosome 8. The man is karyotypically normal. What is the probability that this couple's child will inherit a duplicated or deficient chromosome 8 that results from crossing over within this pericentric inversion
