How do muscles work together to created movement
Answer
Basically they contract and then relax in different places back and forth.
Explanation:
When you move your arm for example, parts of that muscle are stretched while other parts become more relaxed to allow for the tension on certain parts. Basically when one part is stretched, the other part is relaxed, so they're always working together.
How can scientists use the fossil record to find evidence of relationships between different species?
Answer:
Fossils from different areas are different from the ones you might find today, they have had the marrow mostly washed out of them if they are old, and they can use fossil records to find the date between fossils as well.

1. Name the two processes that occur in meiosis that increase genetic variation
The two factors are: crossing-over and independent assortment. Crossing over: In Prophase I of Meiosis I, homologous chromosomes line up their chromatids and “cross-over”, or exchange corresponding segments of DNA with each other. This produces genetic variation by allowing more combinations of genes to be produced.
Which of the following is a general term describing any level of the biological classification system scientists use for living things?
taxon
gene
kingdom
genus
A taxon is a general term that describes any level of the biological classification system scientists use for living things.
What is a taxon?A taxon (plural - taxa) is a term used by taxonomists or biologist to describe a taxonomic group of any rank.
The taxonomic groups we have in biological classification are as follows:
KingdomDivisionClassOrderFamily GenusSpeciesAny of the above ranks in taxonomic classification can be regarded as a taxon.
Therefore, a taxon is a general term that describes any level of the biological classification system scientists use for living things.

Why is it difficult to cool off if the humidity is high?
Derive observation from above picture
Answer:
what picture. attach it.
Students model codominance in fish. B is the allele for blue coloring, and R is the allele for red coloring. They draw three fish with different-colored scales and fins. Their drawings are shown in the table.
Select the boxes to show the genotypes for each fish shown.
The phenotype of the fish when both R and Bl are present will be Blue and Red while the genotype will be BR.
What is co-dominance?Co-dominance in genetics is the condition in which alleles of a gene are both dominant in that when both are present in an organism, the organism will show the phenotype of both alleles.
Since the alleles B for blue coloring, and R for red coloring are both dominant, when both are present in the fish, the phenotypic coloring in the fish will be blue and red.

The diagram below shows a cross section view of a flower.
What is the function of structure Y?
A.
to attract pollinators to the flower
B.
to form the floral organs
C.
to attach the flower to the main stem
D.
to protect the developing bud
Answer: Flowers are the reproductive organs of angiospermophytes (flowering plants) and contain male and female structures most flowers possess both male and female structures (monoecious), but some may only possess one structure (dioecious)
Explanation: so the answer is A.
Describe the similarities you observe between the major stages in the life cycles of flowering plants and non-flowering, seed-bearing plants.
Answer:
Seeds are found in both flowering and non-flowering plants. Both plants reproduce, the difference being that the former reproduces through blossoms, whereas the latter reproduces through seeds or spores. Because both flowering and non-flowering plants have chlorophyll, they can both photosynthesise.
Explanation:
Which organisms are eukaryotes?

Examine the words,
impulse, presynaptic cell, neurotransmitters, receptors, postsynaptic cell,
What idea can be described using all the words listed?
The synapse is the place where the electrical impulse is modulated, it begins with a chemical-electric discharge in the presynaptic cell and the postsynaptic cell has the receptors that receive and are activated by the neurotransmitter.
What is synapse?It is the functional relationship of contact between the endings of nerve cells.
This communicative process between neurons begins with a chemical-electric discharge in the membrane of the emitting cell (presynaptic cell).
When said nerve impulse reaches the end of the axon, the neuron secretes a substance that lodges in the synaptic space between this transmitting neuron and the receiving neuron (postsynaptic cell), in turn, this neurotransmitter is responsible for exciting another neuron.
Therefore, we can conclude that the synapse is the place where the electrical impulse is modulated, it begins with a chemical-electric discharge in the presynaptic cell and the postsynaptic cell has the receptors that receive and are activated by the neurotransmitter.

what evidence is supporting the benefits of stem cell research
Answer:
Where are the answer choices?
Explanation:
of translation happens when the ribosome hits a stop codon on the mRNA. 2. of translation always happens at the start codon of the mRNA. 3. The process, performed by the ribosome, of reading mRNA and synthesizing a protein is called . 4. The RNA that has an amino acid attached to it, and that binds to the codon on the mRNA, is called a . 5. Amino acids are attached to tRNA by enzymes called .
We can confirm that when a ribosome hits a stop codon, the translation process halts, which is the process by which the mRNA is read to produce a protein through the use of tRNA and aminoacyl-tRNA synthetase.
What are the distinct types of RNA?The process of translation in order to produce a protein has many parts. The mRNA is the messenger RNA that holds the genetic code needed to create the protein, this is read by the ribosomes. These ribosomes use the aminoacyl-tRNA synthetase enzyme to attach the corresponding amino acids to the transfer RNA or tRNA and later to the protein itself.
Therefore, we can confirm that when a ribosome hits a stop codon, the translation process halts, which is the process by which the mRNA is read to produce a protein through the use of tRNA and aminoacyl-tRNA synthetase.
