Answer:
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. Paleontologists can determine the age of fossils using methods like radio metric dating and categorize them to determine the evolutionary relationships between organisms

Which statement best describes the result of meiosis?
A.
It produces body cells.
B.
It causes alleles to deform.
C.
It prevents genetic mutation.
D.
It produces reproductive cells.
Answer: The correct answer is D. It produces reproductive cells.
Explanation: Confirmed correct.
The statement that best describes the result of meiosis is it produces reproductive cells. The correct option is D.
What is meiosis?Meiosis is a reduction division, thus the sex cells that create the gametes will do so while going through meiosis. The number of chromosomes in the gametes will be halved from that of an adult human.
A single cell splits twice during the meiotic process, resulting in four cells with half the original genetic material. These cells—sperm in men and eggs in women—are our sex cells.
Four haploid daughter cells with chromosomal variations from the original parent cell and half as many chromosomes as the original parent cell are the result of meiosis (diploid).
Therefore, the correct option is D. It produces reproductive cells.

The only difference in the chemical structure of DNA between various organisms is---
the number of nucleotides present
the order of base pairs
the variety of bases
the number of bases in a codon
Answer: the order of base pairs
Explanation: i took this quiz lol
l
The only difference in the chemical structure of DNA between various organisms is the order of base pairs that is present in the second option. The order of base pairs is different in different organisms.
What is the base-pair role present in the DNA?There are two DNA strands in double-helical DNA that are linked together by hydrogen bonds, such as adenine's double hydrogen bond with thymine and guanine's triple bond with cytosine. All the organisms that belong to different species have the same bases and same nucleotides, such as ATP, GTP, CTP, and TTP, but the base pair order is different, and that makes them unique. The gene having some specific sequences in an animal is different from the gene of another animal, and this is due to the various base pairs in the DNA.
Hence, the only difference in the chemical structure of DNA between various organisms is the order of base pairs that is present in the second option.

Lucy is traveling to the top of Pike's Peak. The elevation is 14,000 feet. At the base, her respiration rate is 12 breaths per minute. At the top of Pike's Peak, her respiration rate increases to 20 breaths per minute. Why does Lucy's respiration rate most likely increase at the higher elevation
Answer:
Lucy's respiration rate increases because of the decrease in the atmospheric pressure and the partial pressure of O₂.
Explanation:
As Lucy ascends, the atmospheric pressure decreases. The decrease in this pressure decreases the partial pressure of inspired O₂, which causes less oxygen saturation in the blood. As oxygen is essential for the vital functions of the body, the respiratory rate increases to valance the loss of oxygen. In other words, the oxygen that the body had in one inspiration, now it has to obtain with multiple breaths. The same happens with the CO₂ that Lucy expels from her body.

Where can you find the human sex chromosomes in a karyotype
Answer: According to international conventions, human autosomes, or non-sex chromosomes, are numbered from 1 to 22, in descending order by size, with the exceptions of chromosomes 21 and 22, the former actually being the smallest autosome. The sex chromosomes are generally placed at the end of a karyogram.
dev, s blood report suggest that the X components in his blood has significant increase because he is suffering from an infection disease. Identify X.
Answer:
The X components of Dev's blood, which increase significantly with infectious disease, are leukocytes.
Explanation:
Leukocytes, also called white blood cells, are the cellular components of the blood that are responsible for the body's defenses and protection.
When a pathogen —usually a bacterium— enters the body, an infectious disease occurs. In response to an infection, white blood cells increase in number in order to fight the infection.
This is why the X component of Dev's blood, leukocytes, increases significantly when Dev has an infectious disease.

Do you feel stem cell research is important? Explain.
4 sentences.
Given their unique regenerative abilities, stem cells offer new potentials for treating diseases such as diabetes, and heart disease. Research on stem cells continues to advance knowledge about how an organism develops from a single cell and how healthy cells replace damaged cells in adult organisms.
Yes. Without stem cell research there would be alot more sick people. There would be alot more sick people because Stem-cell research is an area of research that studies the properties of stem cells and their potential use in medicine. As stem cells are the source of all tissues, understanding their properties helps in our understanding of the healthy and diseased body's developmental and homeostasis. Stem cells originate from two main sources: adult body tissues and embryos.

Which statement best describes how the environment influences the traits of an individual?
The environment influences the gene expression which can change the genotype.
The environment influences the gene expression which can change the phenotype.
The environment influences only external factors.
The environment influences only internal factors.
Answer: The environment influences the gene expression which can change the phenotype.
Explanation: TRUST
The environment influences the gene expression which can change the genotype. The correct option is A.
What is gene expression?The methodology by which a gene in a cell is activated to produce RNA and proteins.
Gene expression can be assessed by examining the RNA, the protein produced from the RNA, or whatever the protein does in the cell.
The environment can impact gene expression in a life form, along with the outer environment in which the species is positioned or evolves, as well as the organism's internal world, which encompasses factors such as hormones and metabolism.
Several factors influence gene expression, which would include molecules within the cell, mutations that cause dominant damaging consequences and haploinsufficiency, signaling molecules from neighboring cells and the environment, and epistasis.
The environment influences an individual's genotype but not his or her phenotype.
Thus, the correct option is A.
