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.

Answer:
A. a cell
Explanation:
Cells are the building blocks of life, or, the smallest unit of life. Cells join to make tissues, and tissues join to make muscles, and muscles join to make an organ system. This means that it can't be either of the other two options.

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.

What unique characteristic does the bonding of carbon to other atoms have and why is this important for organic molecules?
Explanation:
The carbon atom has unique properties that allow it to form covalent bonds to as many as four different atoms, making this versatile element ideal to serve as the basic structural component, or “backbone,” of the macromolecules. Individual carbon atoms have an incomplete outermost electron shell.The ability of forming long durable chain is an unique characteristic of Carbon that is important for organic molecules.
The Carbon can form four bond with different atom anf form a long chain of different size. These can also be branched. The long chains are very durable.
Silicon and some other elements can do so but the chains are relatively short and non-durable.
Therefore, the ability of forming long durable chain is an unique characteristic of Carbon that is important for organic molecules.

Answer:
Malthus
Explanation:
He was interested in the idea that the entire human population throughout history had a part that lived in poverty.
It is assumed that the population will grow in areas with a lot of resources until those resources are strained to the point where some residents would have to go without.
Malthus went on to say that factors such as famine, war, and disease in historical populations have worried about the overload crisis it has taken on if left unconfirmed

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.

Could someone help : how does the number of offspring that are produced by an individual typically compare with the fecundity of that individual? What factors create this (think of reproductive potential)
Answer:
The number of offspring produced is often related to the amount of parental care. Typically, the higher fecundity, the lower the amount of time parents devote to caring for the offspring.
The number of offspring that are produced by an individual typically varies with the fecundity, as the higher the fecundity, the lower the parental care per offspring, while a lower fecundity leads to more parental care.
What is parental care in the animal kingdom?Parental care refers to the behaviors of parents for the care of their offspring, and in the animal kingdom, parental care can take many forms, ranging from simple behaviors like providing food and shelter to more complex behaviors like teaching and training offspring and parental care is important for the survival and development of offspring, as it can improve an offspring's chances of survival by providing them with resources, protection, and guidance.
Hence, the number of offspring that are produced by an individual typically varies with the fecundity, as the higher the fecundity, the lower the parental care per offspring, while a lower fecundity leads to more parental care.

After cytokinesis, how many cells have been formed from the parent cell?
Answer:
The cell now undergoes a process called cytokinesis that divides the cytoplasm of the original cell into two daughter cells. Each daughter cell is haploid and has only one set of chromosomes, or half the total number of chromosomes of the original cell.
Explanation:
The phragmoplast, a structure made up of membranes, actin filaments, and microtubules, controls the deposition of the new wall.
What is the role of cytokinesis in plant cell?Higher plant cells have a unique process for cytokinesis, in which the division of a new cell wall partitions the cytoplasm.
Inside the cell is the cell plate. The location of a preprophase band of microtubules and actin filaments determines where the cell plate is located.
After mitosis, a new cell wall must be created and inserted in plant cells during a process known as cytokinesis.
The cytoplasm of the parent cell is now divided into two daughter cells by a process known as cytokinesis in the cell.
Therefore, each daughter cell is haploid and has just one set of chromosomes, or half as many as the original cell.

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.
