If an organism has 6 haploid chromosomes, how many chromosomes are present? 6 12
The number of chromosomes in a haploid cell, which includes an egg and sperm, is half that of a diploid cell, or a normal cell. Therefore, a haploid cell would have 12 chromosomes.
What is Haploid chromosomes?A cell with a single set of chromosomes is called haploid. The number of chromosomes in sperm or egg cells, often known as gametes, is also referred to as haploid.
In humans, gametes are haploid cells with 23 chromosomes—one of each chromosomal pair found in diplod cells—and are hence haploid. The haploid number, commonly known as n, is used to indicate the number of chromosomes in a single pair. n = 23 for people.
Half of the chromosomes found in somatic cells, or the body's typical diploid cells, are found in gametes. Meiosis, a type of cell division that cuts the number of chromosomes in a parent diploid cell in half, produces haploid gametes.
Therefore, The number of chromosomes in a haploid cell, which includes an egg and sperm, is half that of a diploid cell, or a normal cell. Therefore, a haploid cell would have 12 chromosomes.

When we encounter a stressor, the _____ nervous system accelerates the automatic processes in our body, and after the stressor is over, the _____ nervous system returns us to normal functioning?
Answer: The correct answers for the blanks are-
Sympathetic nervous system and
Parasympathetic nervous system respectively.
Explanation:
The sympathetic nervous system is also referred as '' fight or flight'' system of body as it prepares body for an intense activities during any stressful situation.
It accelerates the processes of body in a way that either body needs to "fight" or run away in response to a particular stressor.
On the other hand, the parasympathetic nervous system is the ''rest and digest'' system of the body. It brings calm and relaxes the body by conserving energy through slowing down the processes taking place. So, when the stressor is gone, the body relaxes and comes back to normal function through parasympathetic branch.
Why is the karyotype for people with Turner syndrome written as 45XO
The number 45 means that the subject has 44 normal autosomal chromosomes (22 chromosomes pairs) plus one (1) good sex chromosome (out of the normal homologous pair). The X0 means that the subject, usually a female, lacks one sister chromosome of the homologous X chromosome pair, or has a partial X sister chromosome.

32. Explain the relationship between the central nervous system and the peripheral nervous system. How do
they work together to accomplish a task? (4 points)
The nervous system develops throughout the human body and includes very different elements in their forms and functions. It is divided into two complementary systems, the Peripheral Nervous System (PNS) and the Central Nervous System (CNS).
The SNP includes all the nerve tissue that runs through the body. It has a dual function: to receive information by sensory sensors and transmit them to the CNS, and to activate motor functions controlled by the CNS. It consists of two parts, that somatic, activating the skeletal muscles and that, autonomous, attached to the viscera.
The CNS is the brain and spinal cord. It is the center of information processing.

If there was a large oil spill close to shore, which method would be deployed to prevent a large scale impact on the wildlife?
Answer:
Booms
Explanation:
I just took the test.
If there was a large oil spill close to the shore, the method which would be deployed to prevent a large scale impact on the wildlife are the floating barriers which are mainly booms.
What are Floating barriers?Floating barriers are also referred to as the boom. These are the devices which are placed in the waterbody to control and also contain oil, floating debris, invasive aquatic plants, trash, silt, sediment, and enough turbidity. A floating barrier can be installed either temporarily or permanently in a shore or wildlife.
The most common type of the equipment which is used to control the spread of oil is floating barriers are called as the booms. Containment booms are also used to control the spread of the oil components to reduce the possibility of polluting the shorelines and other resources, as well as to concentrate the oil in thicker surface layers in the shore and also making recovery easier.

How many synapses are crossed in a single reflex arc during a muscle stretch reflex?
In a typical muscle stretch reflex, two synapses are crossed: one between the sensory neuron and the spinal cord and another between the spinal cord and the motor neuron.
Explanation:In the case of a muscle stretch reflex, typically only two synapses are crossed. For example, when a muscle is stretched, signals are sent to the spinal cord via sensory neurons (first synapse). In the spinal cord, these sensory neurons synapse with motor neurons (second synapse) which then send signals back to the muscle causing it to contract and resist the stretch.

Which properly traces the movement of chromosomes during mitosis?
Mitosis consists of sequential stages starting with prophase and ending with cytokinesis, during which the chromosomes condense, attach to spindle fibers, align at the metaphase plate, are pulled apart during anaphase, and are separated into two new nuclei in telophase.
Explanation:To properly trace the movement of chromosomes during mitosis, one must understand the sequential stages involved in this process. Mitosis is a critical aspect of cell division that ensures each daughter cell receives an exact copy of the parent cell's chromosomes.
Prophase: Chromosomes condense and become visible. The mitotic spindle begins to form, but the nuclear envelope is still intact.Prometaphase: The nuclear envelope breaks down, allowing spindle fibers to attach to kinetochores on the chromosomes.Metaphase: Chromosomes align at the metaphase plate, with sister chromatids facing opposite poles.Anaphase: Cohesion proteins dissolve, and sister chromatids are pulled apart by the spindle fibers toward opposite poles.Telophase: Nuclear membranes start to reform around separated sister chromatids, now individual chromosomes, at the poles of the cell.Cytokinesis: The cytoplasm divides, creating two daughter cells, each with a complete set of chromosomes.Calories are units of heat that express the energy value of food.

If transcription occurred from left to right, which strand is the template strand? if transcription occurred from left to right, which strand is the template strand? 5' - tatgcagcacatt - 3' 5' - atacgtcgtgtaa - 3' 3' - atacgtcgtgtaa - 5' 3' - tatgcagcacatt - 5'
Final answer:
The template strand for transcription occurring from left to right is 3' - tatgcagcacatt - 5', as RNA polymerase synthesizes RNA in the 5' to 3' direction by reading this template strand in the 3' to 5' direction.
Explanation:
If transcription occurs from left to right on a DNA segment, the template strand will be the one running in the 3' to 5' direction because transcription proceeds in the 5' to 3' direction. Looking at the provided sequences, the template strand is 3' - tatgcagcacatt - 5' since transcription occurring from left to right would involve polymerase moving along this strand in the 3' to 5' direction while synthesizing RNA in the 5' to 3' direction.
During this process, adenine (A) on the DNA template strand dictates the addition of uracil (U) in RNA, thymine (T) will be transcribed as adenine (A), and cytosine (C) pairs with guanine (G) as usual.
