Answer:
The captive population of golden lion tamarins increase between 1970 and 2007 is explained below in detail.
Explanation:
In the early 1970s, there were 91 lion tamarins in 27 distinctive zoos. Biologists created a strategy to improve the species' survival. The purpose was to improve the quantity and biogenetic variety of lion tamarins. As of 2007, there were 497 lion tamarins in 144 terrariums around the globe. Further, about 154 tamarins from the program have been re-presented to the wild since 1984. These tamarins are components of a strong wild population of more than 651.

DNA binding proteins in prokaryotes regulate gene expression by controlling transcription
true or false
Answer:
True
Explanation:
Gene expression, which involves the transcription of DNA into mRNA and the subsequent translation of mRNA into proteins, is regulated in the cell of prokaryotes i.e. it is kept under control. This regulatory process, however, is done at the TRANSCRIPTIONAL LEVEL, in prokaryotic organisms like bacteria.
DNA binding proteins called transcription factors bind to the promoter region of a gene and either facilitates/enhance the binding of RNA polymerase or inhibits its binding. The enhancers are called ACTIVATORS while the inhibitors are called REPRESSORS.
Answer all 3 wuestions for 25 points and brainliest
Answer:
17. C " TAAGCTG". It would be the replication strand because A always pairs with T and C always pairs with G, so replication strands just have the opposite base as the original strand
18. Transcription is the name given to the process in which DNA is copied to make a complementary strand of RNA. RNA then undergoes translation to make proteins. The major steps of transcription are initiation, promoter clearance, elongation, and termination.
19. Straight hair is controlled by a recessive allele because as you can see the one where is not shaded is the one that has the most. There are only 1 shaded circle or square, out of the 12 other circles or square that is not shaded. This means that it is the recessive allele because people are less prone to getting straight hair, as you can see in that diagram.

Many pine trees grow in the taiga, the largest habitat in the world. Using incredible sources such as nasa research the typical climate conditions in the taiga. Explain why the structure of pine cones helps ensure successful reproduction in the taiga
Answer:
Hard structure of cones protects reproductive parts of pine trees.
Explanation:
The structure of pine cones helps in successful reproduction in the taiga because in pine trees both male and female reproductive parts are present on the same tree that leads to successful reproduction and production of seeds. The pollen from the male cone fall onto the female cone that produces seeds after fertilization process. The structure of cones are hard that protects the male and female reproductive part in that environment.

Breeders will induce mutations in organisms to increase the genetic variation in that organism’s population.
Please select the best answer from the choices provided
T
F
Answer:
The statement that indicates that breeders will induce mutations in organisms to increase genetic variation in the population of that organism is true.
Explanation:
Induced mutations can be produced by the introduction of chemical or physical agents that can alter DNA and produce genetic variation. This, when controlled, can produce physical or functional changes in a manipulated population.
Mutation induction is a technique used by breeders to increase the genetic variation of a population of plants, for example, and make their characteristics improve, such as their resistance or productivity.
why do the antibody numbers remain higher after the first infection than before it?
Explanation:
During a primary infection levels of antibodies slowly increase, peak at around ten days and then gradually decrease. ... The antibodies are produced so quickly by the memory cells that the pathogen is killed off before it can make the person ill.

Answer:
By scent-marking, body language, and a series of vocalizations, red wolves interact. These contain, along with a series of barks, growls, and yaps, the distinctive howl. The howl of the red wolf is somewhat similar to that of a coyote, but is mostly pitched deeper and lasts longer.
Red wolves communicate with one another through vocalizations, body language, and scent-marking. The unique howl may be heard in these, along with a variety of barks, growls, and yaps.
What best define red wolves interactions?Until they become accustomed to people, wolves typically avoid engaging with them.
In general, red wolves create enduring pair connections with one another. There are still more than half of red wolves in captivity. Red wolves live an average of eight to nine years in the wild.
Please make a donation to protect wolves where they belong—in the wild. Fend off the wolves. Although wolves are apprehensive of people, they can lose that fear by becoming accustomed to them.
The howl of the red wolf resembles that of the coyote in some ways, but it is often deeper and lasts longer.
Therefore, red wolves communicate by scent-marking, vocalizations, body language.

What technique did Hershey and Chase use in their experiment that led to the conclusion that DNA, not protein, was the genetic material in viruses?
Answer:
They used radioactive labeling techniques to build two different types of phage.
Explanation:
In 1952, a set of experiments were carried out by American biochemists Alfred D. Hershey (1908-1997) and Martha Chase. They prepared two separate virus samples, one contained DNA labeled with a radioactive isotope and the other contained protein labeled with a different radioactive isotope. They grew the two types of viruses separately, infected bacteria with the two sets of phages and analyzed the bacteria for radioactivity. From the results obtained, Hershey and Chase concluded that the viral genetic material was DNA and not protein, reinforcing the observations previously made by Avery.

How do H-R diagrams help scientists compare new stars with the Sun? In your answer, name one type of data that H-R diagrams do not show.
Answer: Hertzsprung-Russell (HR) diagram is an essential tool used in stellar evolution. In the universe, there are several hundreds of billions of stars. Scientists use the tool, in differentiation, the billions of stars in the world from the sun. In the HR tool, there plotting of the luminosity or energy output of a star, which is plotted on the X-axis of a graph against the absolute magnitude. The sun's magnitude is an absolute of +48, which, when plotted against its luminosity, helps in setting an apparent variance between the sun and any other star. Additionally, the sun has been identified as the primary star with a very high temperature. Hence the tool can locate the sun from other forms of stars. HR diagrams outline data such as temperature and luminosity or energy. However, star distance from the Erath is not a type of data represented in the charts.

Similarities of Mitosis and Meiosis :))
Explanation:
Mitosis and meiosis have different purposes, but share common features in how they work.
Easy Answer:
-Both can divide (option 1)
-Same number of chromosomes as the original cell (option 4)
-Both have the basic 5 phases
Multiple Stages
Both mitosis and meiosis are multistage processes. The stages are interphase, prophase, metaphase, anaphase and telophase. The same general processes occur in each of these stages for mitosis and meiosis. Interphase is cell growth and DNA replication in preparation for cell division. Prophase is when the nuclear membrane degrades. Metaphase is when the chromosomes align in the middle of the cell. Anaphase is when the chromosomes are pulled apart. Lastly, telophase is when one cell splits into two separate cells.
DNA Replication
Mitosis and meiosis both involve duplication of a cell’s DNA content. Each strand of DNA, or chromosome, is replicated and remains joined, resulting in two sister chromatids for each chromosome. A common goal of mitosis and meiosis is to split the nucleus and its DNA content between two daughter cells. Before DNA can be separated between two cells, it must be duplicated and then condensed into a form that can be efficiently transported. The condensed form of DNA is called chromosomes. Chromosomes can be physically pulled apart, and make separating long strands of DNA easier for the cell because the DNA strands become like a tightly wrapped yarn ball.
