Which biome dominates the eastern region of the United States? A)grassland B)Temperate broadleaf forest C)scrubland D)desert

Answers

Answer 1

Answer: The best answer is B. The biome that dominates the eastern region of the United States is the temperate biome. This biome are located in mid-latitude regions therefore in polar regions and tropics. This biome is exposed to warm and cold air which will cause this area to have four seasons.

Answer 2

Answer:

Answer:

Temperate broadleaf forest

Explanation:

I got 100 on the PLATO/Edmentum quiz

Cellular respiration included the metabolic pathways of glycolysis, the Krebs cycle, and the electron transport chain, as represented in the figures. In cellular respiration, carbohydrates and other metabolites are oxidized, and the resulting energy-transfer reactions support the synthesis of ATP. Using the information above, describe ONE contribution of each of the following in ATP synthesis. 1. Catabolism of glucose in glycolysis and pyruvate oxidation. 2. Oxidation of intermediates in the Krebs cycle. 3. Formation of a proton gradient by the electron transport chain.
The alleles for eye color in fruit flies involves one allele that might contain the sequence CCAT. Assume that this allele produces red eyes in a fruit fly, because the allele produces a protein that makes red pigment. Assume that another allele of this gene has a slightly different sequence in the middle: CAAT, instead of CCAT.Which of the statements below is true about the alleles for eye color in fruit flies? Which of the statements below is true about the alleles for eye color in fruit flies? A) The alleles for eye color produce the same phenotype. B) The small change in the DNA sequence causes the allele to produce a different protein, resulting in the production of white eyes instead of red eyes in the fruit fly. C) Changes in the sequence of DNA bases in a gene do not contribute to genetic variation in the fruit fly population

Proteins that tag pathogens for destruction by immune cells are called A. antibodies. B. antigens. C. histamines. D. interferons.

Answers

Proteins that tag pathogens for destruction by immune cells are called (D) Interferons. Interferons are group of proteins used for signals. It is produced whenever there is a pathogen (whether a virus, bacteria, parasites or tumor cells) present in the body. It causes its neighbor cells to increase their anti-viral defense.

Answer: Antigen

The antigen are proteins in the cells of the body.Out of over 100 different antigens that have been identified, there are six that have been shown to be the most important in organ transplantation. Of these six antigens, we inherit three from each parent. It is rare to get a six-antigen match between two people, especially if they are unrelated. HLA(human leucocyte antigen) typing is done before the transplant to ensure high probability of success.

A person can make antibodies against another person’s HLA antigens. If a recipient has strong antibodies against a donor’s HLA, the risk of rejection is high and a donor would be declined for that recipient. so the type of antigens are tested for the compatibility before a transplant to ensure high probability of success and lower the rate of rejection.

What will happen if we put a Rhoeo leaf in plain water?

Answers

If we put a Rhoeo leaf in plain water, the water concentration of the leaf cells will be higher than that of the plain water. The aim is to balance water concentration on the inside and outside of the organism. So, the water will exit the leaf cells, which will consequently shrink in size. The most of the cells will shrink in size, causing the leaf to shrink, too.

when we put a rheo leaf in plain water,due to high salt concentraion within the leaf and less salt concentration in the water outside,the salts will flow outwards into the water there by shrinking the leaf and giving it a spherical shape.

The processes of transformation and transduction are important to which kingdom and why?

Answers

Bacteria: Both processes provide the Bacteria with new genes that might provide new ways of dealing with environmental changes.

Final answer:

Transformation and transduction are crucial processes in the Kingdom Bacteria and to some extent in the Kingdom Archaea. They both contribute to genetic variation in bacterial populations, aiding in their adaptability.

Explanation:

The processes of transformation and transduction are vital in the Kingdom Bacteria (and also play roles in the Kingdom Archaea). Transformation involves a bacterium taking in DNA from its environment, allowing the bacterium to acquire new traits—this can potentially include pathogenic traits.

Transduction, meanwhile, is a process whereby a virus (a bacteriophage) transfers DNA from one bacterium to another, leading to genetic recombination. Both processes aid in increasing genetic variability in bacterial populations, which can help these organisms adapt to changing environmental conditions.

What evidence suggests that vertebrates are more closely related to echinoderms than are any other invertebrate phyla? What evidence suggests that vertebrates are more closely related to echinoderms than are any other invertebrate phyla? a.Shared DNA sequences b.Shared morphology c.Shared patterns of development

Answers

Answer:

The correct answer is option a. "Shared DNA sequences".

Explanation:

The most reliable evidence that suggest that vertebrates are more closely related to echinoderms than are any other invertebrate phyla is the fact that vertebrates share DNA sequences with echinoderms. Among the different genes that have been analyzed between vertebrates and echinoderms, the genes involved in immunology and biomineralization are the ones practically identical among these two categories of species.

How does the structure of a compound influence its function?

Answers

Because it determines if it is isolated or not. This means if other substances can enter or not. This usually relies on the membrane with it´s pores. The pores help the membrane be selectively permeable in what it lets in and out.

Answers

The answer to the question stated above is letter C.

>>>FACT<<<
>Chimpanzee mothers in the Tai Forest, instruct their children in tool use. Chimpanzee mothers assist them in placing the nut in the anvil in the proper way.

The correct answer is:

c. tool-making was a defining characteristic of humans

Explanation:

They believed that the tool making was a characteristic that was possessed by humans.The initial stone toolmaking increased by at least 2.6 million years ago. The Early Stone Age covers the most basic stone toolkits made by early humans. The Early Stone Age in Africa is comparable to what is described the Lower Paleolithic in Europe and Asia.
