PROJECT: BUILDING DNA
The structure of DNA resembles a twisted ladder called a double helix. For this project, you will build a DNA molecule by
placing its basic parts together like pieces of a puzzle.
The structure of DNA resembles a twisted ladder because both strands are linked by hydrogen bonds.
What is DNA?Deoxyribonucleic acid (DNA) is a double helix composed of two long chains of nucleotides linked by hydrogen bonds.
In DNA there exist only four different types of nucleotides (i.e., Guanine, Cytosine, Thymine and Adenine).
In conclusion, the structure of DNA resembles a twisted ladder because both strands are linked by hydrogen bonds.

Which is the BEST statement about joint flexibility? A. It is constant for any joint type. B. It is constant within a family. C. It is consistent between an individual's joints. D. It varies from joint to joint. Please select the best answer from the choices provided. A B C D.
Which is the BEST statement about joint flexibility?
Answer : D
Explanation : It varies from joint to joint.
Hope this helps you!
The amount of flexibility can vary greatly from joint to joint and is affected by various factors such as joint structure, muscle strength and elasticity, age, and physical activity level. Hence option D is correct.
What is joint flexibility?Joint flexibility refers to the range of motion (ROM) of a joint or a group of joints. It is the ability of a joint to move through its full range of motion without causing any pain or discomfort.
Joint flexibility is an important aspect of physical fitness and is essential for performing daily activities and participating in sports and exercise.
Joint flexibility is determined by several factors, including the anatomy of the joint, the length and elasticity of the muscles surrounding the joint, and the presence of any injuries or medical conditions affecting the joint.
Some joints, such as the shoulder joint, are naturally more flexible than others, like the knee joint.
Flexibility can vary between individuals and between different joints in the same individual. For example, someone may have very flexible hip joints but limited flexibility in their shoulder joints.
Similarly, an individual's joint flexibility can also be influenced by age, gender, and activity level.
Hence option D, It varies from joint to joint. is correct.

compared to parasympathetic ganglia, sympathetic ganglia are __________.
Compared to parasympathetic ganglia, sympathetic ganglia are autonomic ganglia of the sympathetic nervous system that prepare the body for emergency situations, such as: defense or flight reactions to a dangerous situation.
In the parasympathetic ganglia, the axons of neurons are characterized by being very long and reach the very structure of the target organ before making contact with the second neuron.On the other hand, these ganglia activate the parasympathetic system that has to do with energy recovery situations such as: activating digestive secretions, reducing blood flow to the brain, which causes drowsiness.In the sympathetic ganglia, axons originate from neurons located in the lateral horns of the spinal cord and exit through the anterior roots of the spinal nerves, along with those of the motor neurons.These ganglia activate the sympathetic system that prepares the body for dangerous situations causing: increased heart rate, blood pressure, respiratory rate, etc.Therefore, we can conclude that compared to parasympathetic ganglia, sympathetic ganglia are autonomic ganglia of the sympathetic nervous system that prepare the body for emergency situations.

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.

True or False: The right and left lungs are the same size.
Answer:
False is the correct answer
Explanation: the lungs are different sizes due to accommodating different organs. Left is smaller. Right is larger yet shorter.
The cerebral nuclei are also called the basal nuclei and sometimes are incorrectly called the basal ganglia. Why is this incorrect
It is incorrect to name basal nuclei as basal ganglia because the term 'ganglia' refers to clusters of cell bodies in the peripheral nervous system (PNS). The basal nuclei are a group of subcortical nuclei.
The basal nuclei are a group of subcortical nuclei located deep in the cerebral hemisphere and midbrain.
The basal nuclei can be defined as a region of the brain that is involved in muscle coordination and movement.
The term ganglia make reference to a group of neurons outside of the central nervous system in the peripheral nervous system (PNS).

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.

Explanation:
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.
