Answer:
Carbon dioxide provides the carbon that is the building block of all life. Plants consume carbon dioxide to grow and animals consume plants to obtain the necessary carbon for existence. ... All plants and animals die. The carbon eventually becomes coal, natural gas and crude petroleum locked inside the earth
Risk of toxicity is higher with fat- vitamins. True or False
Answer:
True
Explanation:
The fat-soluble vitamins, A, D, E, and K, are stored in the body for long periods of time and generally pose a greater risk for toxicity than water-soluble vitamins when consumed in excess. Eating a normal, well-balanced diet will not lead to toxicity in otherwise healthy individuals.

At the completion of meiosis I, are the cells diploid or haploid? Explain.
Answer:
During meiosis I, the cell is diploid because the homologous chromosomes are still located within the same cell membrane. Only after the first cytokinesis, when the daughter cells of meiosis I are fully separated, are the cells considered haploid.

One of the roles of ecological succession is to encourage biodiversity in a habitat. Ecological succession occurs in stages and permits a habitat to allow new species to grow in number as the habitat A)is destroyed B)remains the same C)undergoes change D)is relocated
Ecological succession occurs in stages and permits a habitat to allow new species to grow in number as the habitat undergoes change. Thus C is the correct option.
What is ecological succession?Ecological succession is defined as the process through which the mix of species and habitat in an area changes over time. Gradually these communities replace one another until a climax community like a mature forest is reached, or until a disturbance, like a fire, occurs.
There are two major types of ecological succession namely primary succession and secondary succession. Primary succession occurs when a new patch of land is formed or exposed for the first time.
Secondary succession occurs when a climax community or intermediate community is impacted by a disturbance.

Which organisms obtain energy from dead or decaying matter? Select two options.
groundhogs
daisies
earthworms
bacteria
humans
phytoplankton
Earthworms and bacteria organisms obtain energy from dead or decaying matter. Thus, the correct option is C and D.
What is organic matter?The term "organic matter" refers to material that contains carbon compounds produced by living things. Lawn trimmings, leaves, twigs, branches, moss, algae, lichens, any animal parts, sewage sludge, sawdust, insects, earthworms, and bacteria are just a few examples of what it includes.
The main decomposers in many ecosystems are fungi and bacteria, which utilise the chemical energy in dead matter and wastes to power their metabolic processes. Detritivores, sometimes known as trash or debris eaters, are other types of decomposers. Typically, these are creatures with several cells, like vultures, earthworms, crabs, or slugs.

Answer:
C, D
Explanation:
i took the test
Enzyme activity generally increases as temperature increases within an enzyme’s optimal range because an increase in temperature causes an increase in molecular motion. This increase in molecular motion results in the enzyme and its substrate coming into contact with each other more often. At too high a temperature, however, the enzyme will become denatured and no longer be able to function. As the video describes, that is what happens when someone has a high fever.
What do you think happens to enzyme activity as temperature decreases outside an enzyme’s optimal range? Explain your answer in terms of molecular motion.
This most reliable temperature is commonly around human frame temperature (37.5 °C) for the enzymes in human cells. Above this temperature, the enzyme shape begins to interrupt down denature given that at better temperatures intra- and intermolecular bonds are broken because of the enzyme molecules' advantage of even greater kinetic electricity.
Each enzyme has a temperature variety in which a maximal charge of response is accomplished. This maximum is referred to as the temperature most desirable of the enzyme. The most excellent temperature for maximum enzymes is set at ninety-eight. 6 tiers Fahrenheit (37 ranges Celsius). There also are enzymes that work nicely at decreased and better temperatures.
Most activity is accomplished on the enzyme's ultimate temperature. The lively website online of the enzyme modifications shape as the temperature rises above the surest temperature, resulting in a decline in interest. Above and under the highest quality temperature, activity decreases.
Most enzyme functions are done at 37∘C in humans due to the fact the enzymes are capable of holding their structure at that temperature, allowing it to break down complex molecules efficiently.

Hair color is determined by a single gene with a series of alleles, each resulting in different colors. Black, brown, blond and other hair colors are examples of___?
A. incomplete dominance
B. multiple alleles
C. sex-linked trait
D. polygenic traits
Answer:
dissimilar appearence or properties.
Explanation:
Hair color is not so simple as that. Most traits, especially those as complex as color, are controlled by many alleles at many loci. That's why there are different kinds of brown, blond, and red hair in the population. There is no "hair color gene." A fascinating paper came out a few years ago, identifying dozens of SNPs playing a role in hair and eye color. It's a deep, deep rabbit hole that we have only begun to plunge into.

What is another way nitrogen is added back into the atmosphere BESIDES animal waste, but is too unreliable to count on?
Answer:
Plant and animal wastes decompose, adding nitrogen to the soil. Bacteria in the soil convert those forms of nitrogen into forms plants can use. Plants use the nitrogen in the soil to grow. People and animals eat the plants; then animal and plant residues return nitrogen to the soil again, completing the cycle.
Q6.2. There are many diseases that do not infect a person more than once, such as chicken pox
and measles. What is responsible for this lifetime immunity?
The innate immune response, because barriers to entering the body improve with age.
The innate immune response, because adults have more white blood cells than children.
The acquired immune response, because antibodies are developed from previous infections.
The acquired immune response, because it responds rapidly to broad classes of pathogens.
The responsible for this lifetime immunity is the acquired immune response because antibodies are developed from previous infections. The generation of antibodies is a response to these infections.
The acquired immune system eliminates pathogenic organisms and any toxic molecules they produce.
The acquired immune system has two mechanisms of action: humoral immunity and cellular immunity.
Humoral immunity, also known as antibody-mediated immunity, involves the activation of specific blood cells (B cells) and subsequent secretion of antibodies when in contact with a pathogen.
Thus, the acquired immune system develops specific antibodies as a response to infections (e.g., chickenpox and measles).
