Answer:
The correct answer is - sex and blood type.
Explanation:
Different organisms have different traits some are passed from the parents and other traits are developed by environmental influences. The traits that are passed from parents to the offspring are determined by the genes they inherited from the parents. In humans, sex is determined by the genes that present on the chromosomes and make the chromosome X chromosome or Y chromosome. The presence of the Y chromosome determines maleness.
Similarly, the blood group is determined by the genes, there are three alleles of the ABO gene present on chromosome 9; A. B. and O each allele code for a different antigen which helps them categorizing in blood groups.
Neurotransmitters are defined by four essential characteristics. These are: Neurotransmitters are synthesized within presynaptic neurons. Depolarization of a neuron results in the release of a neurotransmitter, which exerts a multitude of actions on the postsynaptic neuron. Their action on postsynaptic neurons can be replicated by administering a drug that mimics the activity of the endogenous neurotransmitter. Their action in the synaptic cleft is terminated by a specific action. A, C, and D only
Answer:
The correct answer is A, C, and D only.
Explanation:
A neurotransmitter is a biomolecule, generally synthesized by neurons, which is poured from vesicles in the presynaptic neuron into the synaptic gap and produces a change in the action potential of the postsynaptic neuron. Depending on the nature of the neurotransmitter, this can be synthesized in the neuronal soma or in the nerve endings. Some neurotransmitters are synthesized directly in nerve endings thanks to enzymes that have been synthesized in the soma and transported to these endings. Through the interior of the axon flows a current of substances free or enclosed in vesicles, which can be precursors of both neurotransmitters or their enzymes, called axonal flow.Another characteristic of the transmitter function in each of the substances commonly accepted as neurotransmitters is that when administered exogenously as a drug that in reasonable concentrations perfectly mimics the effects of the endogenously released transmitter.
Neurotransmitters should be defined by four essential characteristics. It involved the A, C, and D only.
What are Neurotransmitters?Neurotransmitters refer to the chemical messengers in the body that should transform the message from the nerve cell. Also, it should be synthesized in neurons and stored in the presynaptic terminal. It should be the vital attribute at the time when the chemical should mimic the activity of endogenous due to which it gets a similar response. Also it eliminates the activation site.

What does the diagram represent
Answer:
I wanna say C but im not sure.
Explanation:
The reviewers suggested that you think more carefully about your hypothesis and experimental design. For a chemical to make a good cancer treatment, it is not enough that it harms cancer cells. The chemical needs to have a selective effect on cancer cells--that is, it needs to harm cancer cells much more than it harms normal (noncancerous) cells.
You decide to run a new experiment to test the hypothesis that the fungus chemical harms cancer cells selectively. In this controlled experiment, you will test both cancer cells and normal cells under identical conditions. What data would support this hypothesis?
Predict the expected results for cancer cells and normal cells by choosing the correct graph lines and dragging them onto the two graphs.

HURRY PLEASE. Provides energy to an organism to conduct cellular processes A. water B. air C. food D. living space E. carbohydrates
Answer:
Carbohydrates
Explanation:
Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration.

Answer:
A. Chloroplast
Explanation:
Chloroplast, often known as the kitchen of the cell, is where photosynthetic reactions combining light energy from the Sun into chemical energy [Glucose] that is stored as food. They contain a Green Color Pigment called 'Chlorophyll' that initiates the process, but Chlorophyll isn't an organelle, in fact, it is one of the elements of Chloroplasts. Similarly, Thylakoids are membrane-bound elements inside Chloroplast that aid in photosynthesis. While Mitochondria, [Power Houses Of Cells] generate energy for various processes in cells through ATP-Generations.

CELL DIVISION:
Cell division involves two processes namely: mitosis and meiosis. Mitosis results in two daughter cells that are genetically identical to one another. Meiosis, on the other hand, results in four daughter cells that are genetically different from one another. Mitosis and meiosis as types of cell divisions involves phases namely: prophase, metaphase, anaphase and telophase. The major difference between prophase of mitosis and prophase I of meiosis is that homologous chromosomes, which are similar but non-identical chromosomes from each parent, are paired.Learn more about prophase of mitosis and meiosis at: https://brainly.com/question/23718222?referrer=searchResults
In the Hershey/Chase experiment phage proteins and DNA were radioactively labeled and allowed to inject coding material into bacteria. It was found that only radioactively labeled DNA was present in the bacterial cells which had been transformed. If radioactively labeled protein had been discovered in the transformed cells, what would this have told us about the molecules acting in genetics
A virus is made of two main components. A proteic capsid and genetic material. The Hershey/Chase experiment demonstrated that the virus introduces it's genetic material(DNA) inside the host cell to force it to make more viruses. This proved that genetic information is stored in DNA. If the marked proteins were found in the host cell that would have meant that proteins carry genetic information which they don't.

When does cell differentiation occur?
when cells express different genes
when cells express all genes
when cells express the same gene
when cells do not express genes
Answer:
The answer is when the cell express different genes.
Explanation:
Cell differentiation is the process when a cell is changed from one cell type to an other and brings more complexity to the system. A cell before differentiation possess all the genes however their expression in turned off. When some external or internal factors trigger the gene expression it starts the cell differentiation. A multicellular organism undergoes several rounds of cell differentiation during its development. Although cell differentiation changes the size, shape and metabolic activity but the genetic makeup or DNA is never changed during cell differentiation.
Answer:
when cells express differnt genes

When a strip of bark is removed all the way around the trunk of a tree, the tree dies. Explain why.
Answer:
Complete girdling (the bark removed from a band completely encircling the tree) will certainly kill the tree. The reason for damage due to girdling is that the phloem layer of tissue just below the bark is responsible for carrying food produced in the leaves by photosynthesis to the roots.
How do the colors of light affect photosynthesis? Which color was most efficient, medium and least?
Answer:
blue is the most efficient while green is the least efficient
Explanation:
It is well known that different photosynthetic pigments can absorb light at different wavelengths. Thus, the amount of light absorbed during photosynthesis depends on the color of the source light. The leaves have green color because chlorophyll is a photosynthetic pigment that absorbs light at all wavelengths and reflects green light. The best wavelengths are those at 430–450 nm (blue range) and 600–700 nm (red range), thereby photosynthesis is most efficient when plants are illuminated by light sources that emit blue and red lights. Moreover, sources that emit light at the green wavelength are least efficient for photosynthesis.

In two to three sentences, describe why Prunnett squats do not accurately demonstrate how asexual reproduction passes on traits.
Answer:
Punnett Squares are unable to predict the offspring of an asexual organism because there is only one parent from which the offspring can receive genes from. The whole point of a Punnett Square is the fact that it covers all possible offspring outcomes besides mutations from the usual two parents.
In this lab, we discussed several explanations for the evolution of bipedalism. Each hypothesis has its drawbacks and has been criticized. It’s your turn to hypothesize why our lineage evolved bipedalism. Describe some of the advantages of bipedalism (be sure to think about what life would have been like for our ancestors millions of years ago when bipedalism evolved, including their risk of predation, food availability, environment, etc.). Are there any disadvantages to bipedalism? If so, what are they? Taking into account these possible advantages and disadvantages, why do you think bipedalism might have evolved?
Answer and Explanation:
One of the main disadvantages of bipedalism is that it makes it impossible for mothers to carry their young efficiently. This is because bipedalism stimulates the spine's reaction, which may cause the puppies to slip and stay behind, or to be caught by predators. Thus, bipedalism impairs the maintenance of the species, as it leaves the puppies vulnerable.
Bipedalism also causes a decrease in the speed of the body that must be fighting gravity at all times. This can hinder the hunting and flight of predators, which, again, impairs the survival of the species.

What impact do trees have on the food web?
Answer:
Abiotic factors such as latitude and temperature can impact biotic aspects of food web structure like the number of species, the number of links, as well as the proportion of basal or top species. These biotics factors can in turn influence network-structural aspects like connectance, omnivory levels or trophic level. In this way, plants make, or produce, the beginnings of most of the food energy on Earth. This is why plants are called producers. They use some of the food energy to carry out their own functions, and store the rest of the energy in their leaves, stems, roots and other parts.
