A cell removes a toxin it has produced through a chemical reaction. Which characteristic of living things is the cell demonstrating?
the ability to maintain homeostasis
the ability to maintain homeostasis
the ability to grow and develop
the ability to grow and develop
the ability to adapt and evolve
the ability to adapt and evolve
the ability to reproduce
Answer:
Sweating helps the human body maintain homeostasis by cooling the body when it starts to overheat so the internal temperature is kept more or less the same. When sweat evaporates from the skin, it uses up some of the excess heat energy on the skin, thus helping to keep the body cool.
According to cell theory, all living things are made of cells, and living cells come only from other living cells. Gene theory states that the characteristics of living things are controlled by genes, which are passed from parents to their offspring.
Sample answer: The concentration of oxygen in the atmosphere is maintained at 21 percent by a balance between two opposing processes: removal of oxygen from the atmosphere by most living things and addition of oxygen to the atmosphere by living things such as plants.
Sample answer: The human ability to sweat is an adaptation that helps maintain homeostasis in a hot environment by removing heat from the body when it evaporates. Like other adaptations, the ability to maintain homeostasis by sweating evolved by natural selection sometime in our evolutionary past.
a. Gene theory
b. Homeostasis
B
An adaptation is a trait that helps a living thing survive and reproduce in a given environment. Sample example. The chameleon’s ability to change color to match their background is an adaptation.
False
False
Humans began life as a single cell because we develop from a fertilized egg cell.
Gene theory states that genes are passed down from parents to their offspring. Genes determine the characteristics or traits of an organism. If these traits are particularly beneficial or adaptive, natural selection will cause the organisms with beneficial traits to produce more offspring compared to those without the beneficial traits. This results in a change in traits over time, which is called evolution.
No. Evolution is defined as a change in the characteristics of living things over time. Evolution through natural selection causes differences in the amount of offspring produced. Having offspring (or not) is, by definition, more than one generation.
Sample answer. I think that when ancestors of chameleons could change their color to match their background, they were less likely to be detected and killed by predators than those that couldn’t change their color. Therefore, the individuals that had the color matching ability were more likely to survive and reproduce than those that didn’t. This is an example of natural selection. Over time, this led to the population evolving the color changing ability, as those that didn’t have the ability died out.

which term names part of the peripheral nerves system A spinal cord B brain C sensors
Answer:
[tex]\boxed {\boxed {\sf C. \ Sensors}}[/tex]
Explanation:
There are two divisions of the nervous system: the central and peripheral.
The central nervous system (CNS) is made up of the brain and spinal cord. This section processes information gathered from the sensory organs.
The peripheral nervous system (PNS) is divided into the autonomic and somatic, with different functions. Regardless of the subdivision, the PNS is made up of all the nerves and sensory receptors. The nerves are connected to the brain and spinal cord, which allows them to pass information from the PNS (where it is gathered ) to the CNS (where it is processed).
So, the spinal cord (choice A) and brain (choice B) are parts of the central nervous system, not peripheral. The correct answer must be C. sensors
Answer:
C) Sensors

Which parts of DNA provide the code for proteins?
Answer:
The genetic code is the sequence of nucleotide bases in nucleic acids (DNA and RNA) that code for amino acid chains in proteins. DNA consists of the four nucleotide bases: adenine (A), guanine (G), cytosine (C) and thymine (T). RNA contains the nucleotides adenine, guanine, cytosine and uracil (U).
A gene is a section of a DNA molecule that contains the information to code for one specific protein.
The DNA code contains instructions needed to make the proteins and molecules essential for growth, development and health.What is gene?A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. Many genes do not code for proteins.What is DNA?
DNA is the genetic material, which is involved in carrying the hereditary information, replication process, mutations, and also in the equal distribution of DNA during the cell division.

The condition of ketoacidosis is Select one: a. a potentially fatal buildup of acetoacetate or 3-hydroxybutyrate lowering blood pH. b. due to a lowered production of ketone bodies than is normal. c. the increase in pH of the cells due to ketone body production. d. only found when anaerobic catabolism of fat occurs.
Answer:
The correct answer is option A ( a potentially fatal buildup of acetoacetate or 3-hydroxybutyrate lowering blood pH.)
Explanation:
Ketoacidosis results in a type of body metabolic state where the urine concentrations are high in ketone bodies, such as acetoacetic acid , 3-hydroxybutyrate. Fatty acids are converted to ketone bodies, resulting in a very high level of ketone bodies which automatically lowers the blood pH.
Ketoacidosis is of different types, Diabetic ketoacidosis, alcoholic ketoacidosis, starvation ketoacidosis. They are all associated with the accumulation of ketone bodies within the bloodstream. The underlying disease common with ketoacidosis is Diabetes.
Determine the temperature of the bar on the fahrenheit scale.
Answer:
Determining bar temperature on Fahrenheit scale -
The temperature of the bar is given as 50 degrees Celsius.
If we know the temperature on the Celsius scale, we can convert it to the Fahrenheit scale.
We know
C / 5 = (F-32) / 9; Where C is the temperature on the Celsius scale and F is the temperature on the Fahrenheit scale.
Now,
50/5 = (F-32) / 9
Or, (F-32) / 9 = 10
Or, F-32 = 90
Or, F = 90 + 32
Or, F = 112 degrees Fahrenheit.
That is, the temperature of the bar on the Fahrenheit scale is 112 degrees Fahrenheit

which of the following statements is FALSE?
a. alleles are made when one original DNA strand experiences mutations that result in phenotypes that offer advantages
b. the DNA of two alleles must be almost identical. since the trait is the same. But the effect of the allele may be very different!
c. in humans, for every trait we can only have two alleles. but that trait can be controlled by many alleles. there are no limits on how many alleles can control a trait.
d. being diploid means that humans cannot mask the effects of recessive alleles. humans always show both alleles in their phenotypes and genotypes
e. if humans were diploid we would only have one allele per trait
Helpppp pleaseee
Answer:
d. being diploid means that humans cannot mask the effects of recessive alleles. humans always show both alleles in their phenotypes and genotypes
Explanation:
Being diploid means humans carry two sets of chromosomes. Since we have both dominant and recessive gene types, humans can mask the effect of recessive alleles since the dominant trait will be seen in the phenotype or genotype since it is a dominant gene. The effect of the recessive allele will show up only if both diploid genes are recessive.

Energy conversion within a plant cell would be limited most severely by removal of the cell's - A mitochondria B chloroplasts C ribosomes D endoplasmic reticulum
Answer:
The answer is Mitochondria. I took the test and that's the correct answer.
Energy conversion within a plant cell would be limited most severely by removal of the cell's by mitochondria.
What is mitochondria?Mitochondria are membrane-bound organelles (mitochondrial, singular) that produce most of the chemical energy required for biochemical reactions in cells.
The chemical energy produced by mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
Mitochondria contain their own small chromosomes. In general, mitochondria, and thus mitochondrial DNA, are inherited only from the mother.
Therefore, Energy conversion within a plant cell would be limited most severely by removal of the cell's by mitochondria.
