A gene is a section of a double-stranded molecule known as
Answer:
DNA
Explanation:
A gene is a section of a double-stranded molecule known as DNA .
DNA is double-stranded, but only one strand serves as a template for transcription at any given time.
If a DNA segment has the nucleotides AGCCTAATCGCATATGCC, what would be the nucleotide sequence of the complementary RNA strand?
Answer:
Complementary sequence: Nucleic acid sequence of bases that can form a double- stranded structure by matching base pairs. For example, the complementary sequence to C-A-T-G (where each letter stands for one of the bases in DNA) is G-T-A-C.
Consider the graphic of the divergence of one founder species into many additional bird species. This speciation resulted in A) biodiversity due to anatomy and available food resources. B) convergent evolution that resulted in a variety of lineages. C) the survival of mutated individuals within the original population. D) extinction of individuals in the population who died due to starvation.
The correct answer is A) biodiversity due to anatomy and available food resources consider the graphic of the divergence of one founder species into many additional bird species.
Speciation gives the framework for evolutionary biologists to recognize and arrange the earth's biodiversity. Studying speciation calls for that we examine how ecology determines evolution, and vice versa. Speciation is the final supply of recent species, withinside the equal manner that mutation is the final supply of genetic variants inside species (and extinction has similarities to lack of alleles).
What are Inequities in speciation?Inequities withinside the costs of speciation are as a result in all likelihood to make contributions to huge scale biodiversity patterns
Thus it is clear that biodiversity due to anatomy and available food resources Consider the graphic of the divergence of one founder species into many additional bird species.

Which two types of energy need water to work
There are four types of water energy and they are:
Thermal power plants: Steam is used in thermal power plants for the generation of electricity. Pressurized water vapour is used for the running of turbines on the power plants which generates electricity.
Geothermal energy: Here, the water is heated from the inside the Earth for the creation of steam. There are times when steam rises naturally to the surface which is harnessed for the generation of electricity.
Hydropower: Electricity is generated by running water falling from a distance on the turbines. Water is stored in the reservoirs which have potential energy and are released from a lower elevation. This energy is used for the generation of electricity.
Tidal energy: Tidal energy is obtained from the tides created in the ocean. Also, tidal energy is one of the renewable sources of energy.
After which phase does cytokinesis take place? A
Metaphase
B
telophase
C
prophase
D
anaphase
Answer: B
Explanation: Cell division an animals includes mitosis, in which the nucleus divides, and cytokinesis, in which the cytoplasm divides and daughter cells form. So cytokinesis and is a separate process to mitosis and it occurs after telophase, the final stage of mitosis.

In bacterial transformation what is the purpose of heat shock.
Answer:
Heat shock transformation uses a calcium rich environment provided by calcium chloride to counteract the electrostatic repulsion between the plasmid DNA and bacterial cellular membrane. A sudden increase in temperature creates pores in the plasma membrane of the bacteria and allows for plasmid DNA to enter the bacterial cell.

What are the different types of consumers in biology?.
Answer:
primary, secondary, tertiary, and quaternary
Explanation:
Consumers are grouped into four categories – primary, secondary, tertiary, and quaternary. The category in which an animal is situated is defined by its food source within a specific food chain or food web, and not necessarily by its species or habits.
Do you feel that mutations can be good or bad? Explain, give example
Answer:
Often it depends on context, for example whether the mutation helps the organism use a particular food source or fight off a disease present during its lifetime. And some mutations can be beneficial if just one copy is inherited, but harmful if two copies are inherited.

Think about long-neck and short-
neck giraffes. What would happen
over time if all the shrubs and lower
leaves on the trees disappeared?
The short-neck giraffes would die out because the long-neck giraffes are better fit for that environment.
What is long neck of giraffe?A giraffe can reach leaves, fruit, and flowers that are high up in Vachellia or Senegalia (previously Acacia) and other desirable tree species because to its long neck.
Thus, with the exception of elephant, giraffe are suited to take advantage of a region of vegetation that is out of reach for all other terrestrial browsers. The advantage in height is further increased by their 45 cm long tongue and a modified atlas-axis joint that allows the head to stretch vertically.
Giraffe can reach higher than cows, whereas large bulls may browse the tops of small trees. Giraffes mostly consume broad-leaved deciduous foliage during rainy seasons and evergreen plants during other times of the year.

Where do the substrate and enzyme meet?
Answer:
The region of the enzyme where the substrate attaches is known as the active site (since it is where the catalytic "activity" takes place). A substrate enters the enzyme's active site. This results in the formation of the enzyme-substrate complex.
Explanation:
An enzyme will grip (bind) to one or more reactant molecules to catalyze a process. These are the substrates of the enzyme. Different enzymes have varying degrees of selectivity, or "pickiness," about which molecules may be employed as substrates. Some enzymes exclusively take one type of substrate and will not catalyze a reaction even though it is extremely closely related. Other enzymes can function on a variety of target molecules as long as they possess the sort of bond or chemical group that the enzyme is looking for.In certain reactions, a single substrate is degraded into several products. In others, two substrates combine to form a bigger molecule or to swap components. In fact, each form of biological reaction you can think of has an enzyme to accelerate it up!
The region of the enzyme where the substrate attaches is known as the active site (since it is where the catalytic "activity" takes place).
Proteins are made up of amino acid units, and the active site in protein enzymes receives its features from the amino acids it's made up of. These amino acids can have big or small side chains, acidic or basic side chains, hydrophilic or hydrophobic side chains.
The amino acid sequence present at the active site, as well as their placements in 3D space, give the active site its distinct size, shape, and chemical activity. Because of these amino acids, the active region of an enzyme is specially designed to attach to a specific target—the enzyme's substrate or substrates—and assist them in undergoing a chemical process.
