Answer:
i think your answer is true! :)
Explanation:
The statement: The nerve impulse is an electrical current that travels along dendrites or axons is true.
Dendrites are the branched projections of a neuron that receive signals (chemical or electrical) from other neurons or from sensory cells. They are often referred to as the input zone of the neuron, as they receive and integrate incoming signals from other neurons.
A nerve impulse is an electrical signal that travels along the dendrites or axons of a neuron. When a neuron is stimulated, it generates an electrical charge that spreads along its membrane, causing an action potential.
This electrical signal then travels along the axon of the neuron, where it can be transmitted to other neurons or to muscle cells or glands. The speed at which the nerve impulse travels can be influenced by factors such as the diameter of the axon, the presence of myelin sheaths, and the concentration of ions inside and outside of the neuron.Therefore, the mentioned statement about the nerve impulse is true.

Explanation:
during which checkpoint would damaged or improperly replicated dna halt progression through the cell cycle?
Answer:
G2/Growth 2 phase
Answer:
When a cell's DNA is damaged, a sensor protein activates p53, which halts the cell cycle at the G 1start subscript, 1, end subscript checkpoint by triggering production of a cell-cycle inhibitor. This pause buys time for DNA repair, which also depends on p53, whose second job is to activate DNA repair enzymes.

when inactive, the alpha subunit of the g-protein is bound to:
Answer:
the beta-gamma subunit to form an inactive trimeric protein.
Explanation:
When inactive, the alpha subunit of the G-protein is bound to a GDP molecule.
The guanine nucleotide-binding proteins (commonly called G proteins or GTPases) represent an evolutionarily conserved protein family that serves to switch on/off different signaling pathways within the cell.G-proteins are composed of three different subunits: Gα, Gβ, and Gγ subunits.When GDP is bound to Gα, this subunit remains bound to the Gβ subunit in order to form an inactive heterotrimeric protein.When GTP is bound to the G-protein, then Gα dissociates from the other subunits and triggers the activation of the G-protein.In conclusion, when inactive, the alpha subunit of the G-protein is bound to a GDP molecule.

Why isnt there a solar eclipse during every new moon?
Answer:
Eclipses do not happen at every new moon, of course. This is because the moon's orbit is tilted just over 5 degrees relative to Earth's orbit around the sun. For this reason, the moon's shadow usually passes either above or below Earth, so a solar eclipse doesn't occur.

Make this in own words if it's for a test or smth

During one year, the birthrate in a country is 28 births per 1000 people, and the death rate is six deaths per 1000 people. What is the population growth rate?
Answer: 22
Explanation: 28/1000-6/1000=22/1000
Birth rate is the births per 1000 people which is subtracted by the death rate which is the deaths per 1000 people, this phenomenon is known as Population growth rate. So, 22/1000 is the population growth rate for this.
What is Birth Rate?Birth rate is the total number of people born per year per 1000 in the population. Birth rate is also known as Natality.
For example, if 65 births occur per year per 1000 individuals, the birth rate is 65. If it is expressed in the percentage, it is 6.5 per 100 or 65%.
Population is divided into many parts like Juveniles (Period before puberty), adults and Post reproductive adults. Birth rate is higher than the death rate as the population is younger, the faster that population grows.
When the birth rate is expressed as per the age group, this is called the standardized birth rate. Birth Rate is determined by the ratio between the number of live births in a population during a year and total mid-year population for the same year multiplied by 1000.
Thus, birth rate is the births per 1000 people which is subtracted by the death rate which is the deaths per 1000 people, this phenomenon is known as Population growth rate. So, 22/1000 is the population growth rate for this.

Explanation:
Image result for why do you think it is important to understand chemistry and chemical cycles
Chemical cycling plays a large role in sustaining planetary atmospheres, liquids and biological processes and can greatly influence weather and climate. Some chemical cycles release renewable energy, others may give rise to complex chemical reactions, organic compounds and prebiotic chemistry.
Chemical reactions help us understand the properties of matter. By studying the way a sample interacts with other matter, we can learn its chemical properties. These properties can be used to identify an unknown specimen or to predict how different types of matter might react with each other
Answer:
Chemistry is essential for:
1. meeting
2. our basic needs of food,
3. clothing,
4. shelter,
5. health,
6. energy,
7. clean air,
8. water,
