Which of these is a function of the blood?
A.) carry oxygen to cells
b.) carry wastes to be removed
c.)both are functions of the blood
Answer:
C
Explanation:
Blood is needed to keep us alive. It brings oxygen and nutrients to all the parts of the body so they can keep working. Blood carries carbon dioxide and other waste materials to the lungs, kidneys, and digestive system to be removed from the body. Blood also fights infections, and carries hormones around the body.
Answer:
C
Explanation:
usually it is carrying the oxygen to to other parts of the body hence why the blood is red, our blood is blue till it meets oxygen, and occasionally it is carrying the bad waste in the body to get out so i believe that it is C

What evidence did Darwin use to support his theory of evolution? Select three options.
1. in-depth studies of individual organisms
2. observations of fossils
3. finches on different islands had different types of beaks
4. young finches that acquired desirable traits as they aged
5. observations of different species with varying traits
Answer:
2, 3, 5
Explanation:
Darwin's theory of evolution is most often associated with his study of finches.
He noticed that finches present on different islands had different types of beak suited to that particular environment. On one island, the beaks were better suited for cracking nuts. On another, they were long and thin for searching for bugs.
These finches came from a common ancestor, and migrated to different islands. Due to natural selection and lack of intermixing between the islands, the finches developed different traits over time.
He did this work with other species as well, noting that different species had developed distinct features that suited them to their environment.
Darwin also studied fossils, which provided evidence that animal form (anf function) changed over the course of thousands of years. This supported his idea of evolution that resulted from natural selection.

An incident in Donora, Pennsylvania, led to which action?
banning the burning of coal
enacting air pollution laws
banning the use of CFCs
conducting cost-benefit analyses
Final answer:
The incident in Donora, Pennsylvania led to the enacting of air pollution laws, including the passage of the Clean Air Act in 1954. This event significantly influenced environmental regulations, setting emission limits and advancing command-and-control policies to reduce industrial pollution.
Explanation:
The incident in Donora, Pennsylvania had a profound impact on environmental regulation in the United States. In 1948, Donora was the site of one of the worst air pollution disasters in the nation's history, when a combination of a temperature inversion, local industrial pollution, and the burning of soft coal resulted in a thick smog that persisted for five days. As a result of the Donora Smog, which caused severe health issues and deaths among the local population, enacting air pollution laws became a priority.
A significant outcome of this event was the passage of the first Clean Air Act in 1954, a key piece of legislation that was further strengthened in subsequent years. This act led to regulations that directed industries to reduce emissions, and it pioneered the approach of setting limits on pollutants, leading to the improvement of air quality and the reduction of negative health effects.
These air pollution laws are a form of 'command-and-control regulation', wherein governments specify allowable limits of emissions and require the installation of pollution-control technologies in factories, power plants, and on vehicle tailpipes. By enforcing these regulations, firms have to account for the social costs of pollution, representing a move towards the internalization of environmental externalities into the production process.

Mimicry is an resemblance between an organism and another object and they
advantages are???
Answer: Camouflage or deterring predators
Explanation: Mimicry can help an organism blend into its surroundings if they are resembling something in the environment.
It can also help deter predators if they are resembling a poisonous or venomous organism; an example of this is the non-venomous king snake, which mimics the venomous coral snake to deter predators from eating it.
Answer:
1). Its advantages is defense adaption.
2). It makes them look like an uninteresting object.
3). It becomes a specie that potential predators normally avoid because it posses an unpleasant or harmful feature like a foul smell or taste, or a poisonous sting.
Note: Several insects look like dead leaves and bird droppings and so, although noticed, are ignored by their potential predators. Example is in Mullerian mimics, unrelated animals like the striped polecat and the striped weasel of the savanna have similar broad white stripes on a black body. Their enemies associate the conspicuous appearance with the foul smelling liquid they squirt, and so avoid them.

Explanation:
Place the events of protein synthesis in the correct order.
The sequential events of protein synthesis include gene location, DNA unwinding, RNA synthesis, mRNA exit from the nucleus, tRNA initiation, codon-by-codon protein construction, protein folding, and final release into the cytoplasm for functional activity.
The process of protein synthesis involves several intricate steps, each crucial for the accurate construction of a functional protein. Here is the chronological order of these events:
Gene to be Decoded Located by Enzymes:
The initial step involves locating the gene to be decoded. Enzymes play a key role in identifying and preparing the gene for transcription.
RNA Polymerase Unzips and Unwinds DNA:
Once the gene is identified, RNA polymerase initiates the process by unzipping and unwinding the DNA double helix. This allows for the synthesis of a complementary RNA strand based on the exposed DNA template.
RNA is Made by Base Matching:
RNA is synthesized by complementary base pairing. Adenine (A) pairs with uracil (U), thymine (T) pairs with adenine (A), cytosine (C) pairs with guanine (G), and guanine (G) pairs with cytosine (C).
RNA Exits the Nucleus and Binds to Ribosome:
The newly synthesized RNA, known as messenger RNA (mRNA), exits the nucleus and travels to the cytoplasm, where it binds to a ribosome, the cellular machinery responsible for protein synthesis.
tRNA Brings in the First Codon:
Transfer RNA (tRNA) molecules carry amino acids to the ribosome, and the tRNA with the anticodon complementary to the mRNA's start codon initiates the process.
Protein is Built Codon by Codon:
The ribosome reads the mRNA codon by codon, attracting appropriate tRNA molecules that carry specific amino acids. These amino acids are then joined together to form a growing polypeptide chain.
Protein Folds and is Able to Do its Function:
The newly synthesized protein emerges from the ribosome and undergoes folding and post-translational modifications to attain its functional three-dimensional structure.
Protein Detaches from Ribosome and Moves to Cytoplasm:
Once the protein is fully synthesized, it detaches from the ribosome and is released into the cytoplasm, where it can perform its designated cellular function.
Final answer:
In protein synthesis, the correct order is transcription of DNA into mRNA, mRNA processing and transport out of the nucleus, translation of mRNA on the ribosome with tRNA, and finally folding and modification of the polypeptide into a functional protein.
Explanation:
Protein Synthesis Process
The process of protein synthesis involves multiple steps required for a cell to produce a functional protein. Firstly, the sequence of nucleotides in DNA is transcribed into a messenger RNA (mRNA) copy during transcription. This mRNA then exits the nucleus and travels to the ribosome. Here, transfer RNA (tRNA) molecules bind to the mRNA in a process called translation, where each tRNA carries a specific amino acid that is added to the growing polypeptide chain. After translation, the polypeptide is folded into its functional three-dimensional shape, which can be followed by further post-translational modifications and transport to the appropriate location within the cell or beyond.
Transcription of DNA into mRNA
Processing and exiting of mRNA from the nucleus
Translation of mRNA by ribosomes with the aid of tRNA
Folding and possible modification of the polypeptide chain into a functional protein
Incorrect ordering, such as starting with 'protein synthesis on the ribosome' or 'tagging in the vesicle' before the transcription and translation processes, does not accurately describe the correct sequence of protein synthesis.
Why would it be important to know the possible genotypic and phenotypic ratios of different genetic crosses?
Which do you think has a stronger influence on a plant - gravity or light?
How could you design a new experiment to test this?
Influence of plant under gravity or light is described below.
Explanation:
Plants' growth response to gravity is known as gravitropism; the growth response to light is phototropism. ... As a result, root cells on the upper side of the root grow longer, turning the roots downward into soil and away from the light. Roots also will change direction when they encounter a dense object, such as a rock.Geotropism (also called gravitropism) is the directional growth of an organism in response to gravity. Roots display positive geotropism when they grow downward, while shoots display negative geotropism when they grow upward. ... These cells contain small bodies that sink to the bottom of the cells in response to gravity.Tropisms are growth-mediated plant movements that help plants to respond to changes in environmental stimuli. ... The plant response to gravity (gravitropism) and the response to unidirectional light (phototropism) have long been shown to be interconnected growth phenomena.Final answer:
An experiment to discern whether gravity or light has a stronger influence on plants could involve observing plant growth under varying conditions of light and simulated gravity, employing methods such as clinostats for gravity and directional light sources.
Explanation:
The question about whether gravity or light has a stronger influence on a plant is rooted in the field of Biology. The phenomena of gravitropism and the effects of red and blue light on plant growth and metabolic activities are pivotal to understanding these influences. Gravitropism is the growth response of a plant in relation to the force of gravity, with roots showing positive gravitropism by growing downwards and shoots showing negative gravitropism by growing upwards.
Designing an Experiment:
To test the stronger influence between gravity and light on a plant, you could design an experiment where plants are grown in two sets of conditions - one where light direction varies and gravity is constant, and another where gravity varies and light direction is constant. This could involve using a controlled environment with artificial light and a rotating space to simulate changes in gravity. Observing growth patterns, direction, and general health of the plants in these varied conditions would offer insights into which factor has a stronger influence.
For instance, by rotating plants on a clinostat to simulate microgravity and using directional light sources, we can observe differences in growth direction and vigor as each variable changes. This comparative study would contribute valuable insights into plant responses.
