What is the current to the following DNA strand TATTAGATTACA
Answer:
ATAATCTAATGA
Explanation:
Nucleic acid sequence of bases that can form a double- stranded structure by matching base pairs. DNA has four nucleobases: adenine, thymine, guanine, and cytosine. The nucleobases in a DNA strand have preferred partners to form hydrogen bonds with. Cytosine pairs with guanine, and adenine pairs with thymine. These are the base pairing rules that allow DNA replication and protein synthesis to happen.
12. Flowers whose reproductive structures consist only
of stamens would be able to produce
A) fruits with seeds
B) fruits without seeds
C) pollen
D) ovules
Answer:
Pollen reproductive structures consist only
of stamens would be able to produce
Explanation:
No C is the answer
Reproductive structures are structures that make up the reproductive organs of a particular organism. These structures could include either female or the male reproductive organs.
Flowers with reproductive structures that comprise of only stamen would produce only pollen (option c).
Stamens are reproductive organs found in plants and they are male reproductive organs. For fruits with seeds to be formed the male and female reproductive organs must come together to produce a fruit.
Flowers with only the stamen will produce only pollen which is a male gamete that needs to be joined to the female gamete, ovary produced from the female reproductive structure (pistil) in a plant to produce a fruit.

B. Mutualistic
C. Predator-Prey
D. Parasitic
Answer:
C. Predator-Prey
Explanation:
There are predator-prey relationship between ants and antlions.
The type of relationship between the ant and ant lion is Predator-Prey. The correct option is C.
What is predator-prey relationship?Predator-prey relationship implies to the interactions among the two species where one species is the killed food resource for the another one.
The organism that feeds is referred to as the predator while the organism that is fed upon is basically the prey. There are mainly most variety of illustrations of predator-prey relations.
Competition as well as predation are ecological interactions but are not symbiotic.
Predation usually does not take place over a long period of time, along with the competition is an indirect interaction on other resources.
Predation is a symbiotic interaction in which one species sustains life on costuming the another species.
The species that win is the predator, and the species that is lost up is the prey.
Thus, the correct option is C.

A mammal's red blood cells produce the protein hemoglobin, which carries oxygen through the bloodstream. Its hair follicle cells do not produce hemoglobin. Which statement is true about these differences? A) The red blood cells contain different genes than the hair follicle cells, causing the cells to differentiate B) The red blood cells contain DNA, but the hair follicle cells do not C) A red blood cell and hair follicle cell have the same genes, but they are expressed differently D) The hemoglobin is produced from recombinant DNA, which is only found in red blood cells
Answer:
C) A red blood cell and hair follicle cell have the same genes, but they are expressed differently
Explanation:
All cells of a living organism contain the same genetic sequence i.e. they contain the same set of genes, however, differences in the expression of these genes may occur. This is responsible for the different specific roles or functions played by organs of the body system.
The expression of a gene refers to the process by which a gene is transcribed and translated into a protein molecule, which is responsible for traits in the body. Genes are expressed differently in order for certain cells to function differently and specifically. For example, difference in expression of genes is responsible for the ability of red blood cells to produce hemoglobin and the inability of hair follicle cells to, even if they contain same genes.
