Answer:
Several billion years after its life starts, a star will die. How the star dies, however, depends on what type of star it is. Stars Like the Sun. When the core runs out of hydrogen fuel, it will contract under the weight of gravity. However, some hydrogen fusion will occur in the upper layers. As the core contracts, it heats up.

suggest why an MRSA infection may have to be treated with many different antibiotics
Answer:
A trio of antibiotics that had become powerless against MRSA decades ago proved effective in infected mice when used together.
Although more testing is needed, the results suggest that combinations of already-approved antibiotics might add to our options to combat MRSA infections.

Which of the following statements is correct? Which of the following statements is correct? The sperm and egg have twice as many chromosomes as the parental cells. Geneticists use the terms "son" and "daughter" to distinguish between cells resulting from cell division. Meiosis results in gametes that are used in reproduction. Asexual reproduction requires the production of eggs and sperm.
Answer:
Meiosis results in gametes that are used in reproduction.
Explanation:
The sperm and egg have twice as many chromosomes as the parental cells. INCORRECT. Sperm and eggs are the gametes, and they have only half the number of chromosomes that can be found in the germ cells or somatic cells. Gametes are haploid, n. Geneticists use the terms "son" and "daughter" to distinguish between cells resulting from cell division. INCORRECT. The term "daughter cells" is used to refer to the products of cell division. "son cells" is not used at all. Meiosis results in gametes that are used in reproduction. CORRECT. Germ cells are the reproductive, diploid cells produced by testes and ovaries. After meiosis, each germ cell produces four haploid cells that are the gametes. Gametes´ destiny is to merge during fecundation, creating a new diploid cell called the zygote. The zygote is a diploid cell that suffers successive mitosis to form the new organism.Asexual reproduction requires the production of eggs and sperm. INCORRECT. Only sexual reproduction needs gametes. Cells that reproduce asexually duplicate their genetic material and cytoplasmic content and then divide, producing a new cell identical to its parental. This is the case of binary fission, for example.Two interacting systems involved in plant transport are shown here. Which statement best describes the function of xylem and phloem in transporting substances throughout the plant?
Answer:
C. Xylem transport water and nutrients from the soil to the leaves while phloem transport carbohydrates from the leaves to the rest of the plant.

How do animals help recycle carbon atoms?
Answer:
animals, oxygen combines with food in the cells to produce energy for daily activity and then gives off carbon. The carbon combines with oxygen to form carbon dioxide (CO2) and is released back into the atmosphere as a waste product when animals breathe and exhale

In a population of cats, a gene that controls an observable trait has several different alleles. Which of the following best explains how genetic drift might affect the genetic makeup of this cat population over time?
It is a directed process, so it might cause an increase in the gene pool's allele frequencies.
It is a nonselective process, so it might cause an allele to disappear from the gene pool by chance.
It is a random process, so it might cause a population to reach genetic equilibrium.
It is a selective process, so it might cause an increase in the population's genetic variation.
Answer: It is a nonselective process, so it might cause an allele to disappear from the gene pool by chance brainliest?

Which of the following best describes evidence from comparative biochemistry that supports the theory of evolution? (4 points)
Different mechanisms of reproduction exist within the same species.
Different metabolic pathways exist within the same species.
Different species have the same genetic code.
Different species have the same number of chromosomes.
Answer:
1. Asexual reproduction includes fission, budding, fragmentation, and parthenogenesis, while sexual reproduction is achieved through the combination of reproductive cells from two individuals.
2. Anabolism & Catabolism
3. Nearly everybody has the same genetic code. Although the sequences of bases in their DNA (and thus in the messenger RNA that is made from their DNA) vary between species and even between individuals within a species, almost all of them use the same code.
4.Yes, two or more species can have the same number of chromosomes. ... There's much more to differentiating between species than number of chromosomes. For one example, there are proteins present on eggs which 'match up' with proteins on sperm, and these are very specific.

The human immune system detects the presence of pathogens using pattern recognition receptor molecules that bind to common components of pathogens, such as peptidoglycan polymers in cell walls and the flagellin protein of bacterial flagella, known as pathogen-associated molecular patterns, or PAMPs. These receptors are effective becauseGroup of answer choicesthey detect only human immune molecules.they result in rapid evolution of the host immune system.they recognize evolutionarily conserved molecules that are structurally essential to the various bacteria that use them.PAMPs evolve more quickly than other pathogen molecules.
They recognize evolutionarily conserved molecules that are structurally essential to the various bacteria that use them.
What are Pattern recognition receptor molecules?Pattern recognition receptor molecules detect pathogen-associated molecular patterns (PAMPs), which are structurally conserved components of pathogens such as bacteria, viruses, and fungi. These molecules are essential for the survival and function of the pathogen, and are not found in the host's cells.
By recognizing PAMPs, the immune system can quickly identify and respond to a wide range of potential pathogens, without needing to recognize every individual pathogen separately. Therefore, the receptors are effective because they recognize evolutionarily conserved molecules that are structurally essential to the various bacteria that use them.

For what cellular function does the breathing rate help regulate?
Answer: The respiratory system works with the circulatory system to provide this oxygen and to remove the waste products of metabolism. It also helps to regulate pH of the blood. Respiration is the sequence of events that results in the exchange of oxygen and carbon dioxide between the atmosphere and the body cells. The main purpose of respiration is to provide oxygen to the cells at a rate adequate to satisfy their metabolic needs. This involves transport of oxygen from the lung to the tissues by means of the circulation of blood. brainliest?

Hello, jamesundercover06.
The first box, starting on the left, I believe, should be H2O. The second box, the one over the arrow, should be sunlight. The third box, right after the arrow, should be C6H12O6. The final box, then, should be O2. I'm pretty sure that this is right, but if it is incorrect in any way let me know and I will do my best to give you the correct answer.

explain the effects of the production of large amounts of antidiuretic hormone in the human body
Answer:
Antiuretic hormone is a hormone that performs functions related to the reabsorption of water molecules through of the kidneys and with the decrease in the amount of urine accumulated in the body. An excess of antiuretic hormone conditions a retention of water and the elimination of sodium in the urine
Explanation:
Antidiuretic hormone (ADH) participates in regulating the water balance in the body, controlling the amount of water reabsorbed by the kidneys after they have filtered waste from the blood. Excess ADH leads to increased water reabsorption in the collecting duct, with increased urinary osmolarity. If there is too much ADH, water is retained, blood volume increases and affect can lead to nausea, headaches, disorientation, lethargy and hyponatraemia (decreased sodium concentration in the blood).

What is one of the biomolecules for which nitrogen is needed (hint: they help build muscles)?
One of the biomolecules for which nitrogen is needed and that build muscles are the proteins, and the nitrogen is also found in the DNA and RNA that are present in the cells.
What is the significance of the nitrogen in the protein?Proteins play many important roles in the body, including building and repairing tissues, and nitrogen is a critical component of proteins, as it is incorporated into the molecule as a part of the amino acids. Without nitrogen, proteins would not be able to form and perform their many important functions so a diet that is rich in protein is important for athletes and bodybuilders to build and repair muscle tissue.
