Photosynthesis occurs in the chloroplast of the plant cell.
Explanation:
The top strand of the DNA molecule was used as a template to transcribe the mRNA
Agree
Disagree
Why
Answer:
The upper strand of DNA is the "mRNA-like" strand. The lower strand is the strand that is complementary to the mRNA. The -35 region (TTGACA) and -10 region (TATATT) of the promoter sequence and the transcriptional start site (the A) is indicated on the coding strand.A particular diploid plant species has 48 chromosomes, or two sets. A mutation occurs and gametes with 48 chromosomes are produced. If self-fertilization occurs, the zygote will have _____ set(s) of chromosomes.
Answer:
4 sets
Explanation:
Both gametes will each have 48 chromosomes (2 sets). So if fertilisation were to occur, two of those gametes (both with 2 sets each) the zygote will have 4 sets.
If self-fertilisation occurs, the zygote will have two set(s) of chromosomes.
What is self fertilisation?Self-fertilization, also known as self-pollination, is a type of sexual reproduction in which a hermaphroditic or monoecious organism fertilizes its own gametes. This means that the male and female reproductive organs are present in the same individual, allowing for self-fertilization to occur.
In plants, self-fertilization can occur through a variety of mechanisms, including self-pollination by wind or gravity, or by the transfer of pollen from the anther to the stigma of the same flower. Self-fertilization can also occur in animals that are hermaphroditic, such as some species of snails and slugs.
Self-fertilization can have both advantages and disadvantages for the organism. It can ensure reproduction in isolated or low-density populations, but it can also limit genetic diversity and increase the risk of inbreeding depression.

A species that is naturally rare or that has been depleted to dangerous levels is known, according to the Endangered Species Act, as a(n) ________ species.
Answer:
vulnerable would be the answer
Currently, there are more than 1,300 species in the US that are either endangered or threatened. Species that are in risk of going extinct include those plants and animals that have become so scarce.
What Endangered Species Act, as a vulnerable species?A species that is endangered is one that is in danger of going extinct. The two main factors that cause a species to become endangered are habitat loss and genetic diversity loss.
Natural occurrences may result in habitat loss. For instance, dinosaurs had their home removed some 65 million years ago.
A species that has been designated as vulnerable by the IUCN is one that is predicted to go extinct unless the conditions that jeopardize its existence and reproduction change.
Therefore, A species that is naturally rare or that has been depleted to dangerous levels is known, according to the Endangered Species Act, as a(n)(vulnerable) species.

What percentage of body water loss can impact athletic performance?
the small bones in the middle ear that transmit vibrations to the inner ear
Answer:
, yes..............
Explanation:
because the vibrations are transmitted to the inner ear after the bones amplify it
Ossicles are the body's tiniest bones. the malleus (hammer), incus (anvil), and stapes (stirrup). Ossicles amplify sound.
What are ossicles?Ossicles are very little bones; in fact, they are the tiniest bones in the entire human body. The malleus (hammer), the incus (anvil), and the stapes are the names of the three bones because of the forms they make (stirrup). The sound is amplified even further by the ossicles.
In order to reach the eardrum, sound waves must first enter the outer ear and then proceed via the ear canal, which is a very short conduit. The incoming sound waves cause the eardrum to vibrate, and the eardrum in turn transmits these vibrations to three very small bones located in the middle ear. The malleus, incus, and stapes are the names given to these three bones.
Hearing is dependent on a series of intricate steps that convert sound waves in the air into electrical impulses. These steps are necessary for hearing.

True/False: In a neuron at rest, the concentration of sodium ions is 14 times higher outside the cell than inside the cell.
Answer:
true
Explanation:
The sodium and chloride ion concentrations are lower inside the cell than outside, and the potassium concentration is greater inside the cell. These concentration differences for sodium and potassium are due to the action of a membrane active transport system which pumps sodium out of the cell and potassium into it.

Explanation:
Aquistion
the type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only.
Explanation:
A single parent reproduction is called Asexual reproduction
Asexual reproduction is a form of reproduction in which the number of chromosomes or the fusion of gametes is not altered.
What is asexual reproduction?The whole gene pool of their single parent is inherited by the children that are produced by asexual reproduction from either unicellular or multicellular organisms.
With asexual reproduction, just one parent is necessary, two parents participate in sexual reproduction, which results in children with distinct genetic makeup.
A diploid zygote is created during sexual reproduction when two haploid gametes combine during fertilization, budding is an example of asexual reproduction.
Therefore, with asexual reproduction, just one parent is necessary.

in the gel electrophoresis lab, you determined the ________ of three different dna samples.
In the gel electrophoresis lab, you determined the genotype of three different DNA samples.
Gel electrophoresis is a process that allows you to separate fragments of DNA based on size. You place different size fragments of DNA into a gel, then apply current to the buffer surrounding the gel, the DNA will travel through the gel but move at different speeds based on the different fragment sizes. Larger fragments of DNA will move slower than smaller fragment sizes.
Let consider two different alleles:
the bigger allele -- Athe smaller allele -- aThe bigger allele happens to contain a restriction site that is allowed to be cleaved by a restriction enzyme while the smaller allele has a mutation in the restriction site that means that it will not be recognized and cleaved by that same restriction enzyme.
Let us remember that the person will have two copies of this gene and can be:
H0m0zygous dominant AAh0m0zygous recessive aaheterozygous AaAn individual with h0m0zyg0us AA only have versions of the gene that will be cut by the restriction enzymes, each allele producing a small fragment of DNA and a medium-size fragment of DNA
An individual with the genotype aa only has the version of the gene that does not have the restriction site and therefore does not get cut by the restriction enzyme. The DNA sample from this individual will have a single larger fragment of DNA.
When you isolate DNA from heterozygous Aa, half of the DNA isolated has the allele with the restriction site that gets cut into two fragments while the other half will have the allele that does not have the restriction site and remains whole when a restriction enzyme is added.
Therefore, we can conclude that in the gel electrophoresis lab, you determined the genotype of three different DNA samples.

Natural selection, mutation, genetic drift and gene flow are all capable of causing varying changes in allele frequencies in a population. and these changes leads to the violation of Hardy-Weinberg assumptions
Hardy-Weinberg assumption states that; for a population to experience an unchanged allele frequencies, certain conditions must be met by the population such as ; absence of natural, random mating , absence of migration and absence of mutation.

When a nerve impulse reaches the end of an axon of a neuromuscular junction, calcium flows ______ the synaptic knob.
Answer: flows INTO the synaptic knob.
When a nerve impulse reaches the end of an axon of a neuromuscular junction, calcium flows into the synaptic knob.
In a neuromuscular junction, there are three parts. They are the presynaptic terminal or synaptic knob, the synaptic cleft and the postsynaptic terminal. The calcium ions will work in the synaptic knob when the nerve impulse arrives.
Once that the nerve impulse reaches the end of the axon, it will affect the presynaptic terminal. In there, it causes the opening of voltage-gated calcium channels. As a result:
Calcium flows into the presynaptic terminal.The calcium makes the vesicles (with neurotransmitters) descend and fuse with the terminal membrane to release the neurotransmitters to the synaptic cleft.In conclusion, the nerve impulse causes the opening of voltage-gated calcium channels, and calcium flows into the synaptic knob.
