The number of cells that make up organisms are one or more.
What is organism?
Any organic, living system that performs as a distinct individual unit is referred to as an organism in biology. All living things are made up of cells (cell theory). Taxonomy separates species into protists, bacteria, and archaea, which are unicellular microorganisms, or multicellular animals, plants, and fungi. All kinds of creatures are able to reproduce, grow and develop, maintain themselves, and respond to stimuli to some extent. A few examples of multicellular animals that distinguish specialized tissues and organs throughout development are beetles, squids, tetrapods, mushrooms, and vascular plants.
One cell is the bare minimum that living things can possess i.e the minimum number of cells required to form an organism is one.

The ____ of the spinal cord carries motor information from the brain to the muscles and glands
The correct answer is Descending tract of the spinal cord carries motor information from the brain to the muscles and glands.
One of the main pathways by which information travels between the body and the brain is the spinal cord. The brainstem continues caudally into the spinal cord.
Descending tract of the spinal cord.
Descending tracts provide motor information from the brain through the spinal cord to the body, such as commands to move the arm.
The primary characteristic of the musculoskeletal system that promotes locomotion is muscular contraction against a relatively fixed skeletal framework. But to move, muscle fibers need the action potentials produced by the spinal motor neurons of the anterior grey horn. Numerous upper motor neuron pathways that start above the level of tells control these lower motor neurons of the anterior grey horn in both conscious and unconscious ways (i.e. cerebral cortex, cerebellum, etc.). The actions of the upper motor neurons provide stimulatory and inhibitory modulation of the activity of the anterior horn cells, and by extension, the activity of the motor system.

Blood typing is based on the presence of proteins known as ____________ on the outer surface of the erythrocyte plasma membrane.
Answer:
Blood typing is based on the presence of proteins known as antigen on the outer surface of the erythrocyte plasma membrane.
Explanation:
Antigens frequently consist of proteins or carbohydrates and have high molecular weights. Numerous additional substances, including lipids, nuclear acids, as well as polypeptides, can potentially serve as antigens. Haptens include tiny molecules that, when chemically attached to a bigger carrier protein, could also cause immunological reactions. Any chemical that the immune system potentially reacts to is considered an antigen. For instance, parts of the cell wall of bacteria might cause neutrophils to attack violently and right away. The immune system begins an attempt on an antigen when it is discovered that it is not present in the body's original cells. Immunity is the body's capacity to defend itself from pathogens and other foreign substances via its immune system.

Sweet potatoes Ipomoea batatas are hexaploid with 90 chromosomes. (6n = 90).Then they will have 360 telomeres in the G1 phase of the cell.
Chromosomes are the compact form of genetic material. It consists of proteins and DNA that are wound together to form this compact structure. A chromosome consists of two sister chromatids that are joined together by a protein called kinetochore and the point of junction is called the centromere. Each sister chromatid has 2 telomeres and therefore, one chromosome has total 4 chromosomes.
G1 phase of the cell cycle is the one where the cell prepares for the nuclear formation. It synthesizes various mRNA and proteins that are required in the S phase of the cell cycle. There is no change in the number of chromosomes during this phase and hence the number of telomeres will remain 360.

Choose the reason(s) why plants need fertilizer. (there may be more than one answer.)
One of the major reason that plants needs fertilizers is : Fertilizers are food for plants. Fertilizers replace the nutrients that crops remove from the soil. Without the addition of fertilizers, nature struggles to replenish the nutrients in the soil and agricultural productivity would be significantly reduced.
Fertilizers can be defined as a natural or synthetic substance that contains chemical components that enhance plant growth and productivity. Fertilizers either restore chemical elements that previous crops removed from the soil or increase the soil's natural fertility.
In total, plants require a minimum of 16 different elements, the most crucial of which are carbon, hydrogen, oxygen, and phosphorus. Other nutrients are absorbed from the soil, while plants obtain, carbon from the atmosphere, hydrogen, and oxygen from water.
Overall chemical analyses show that the total amount of nutrients in soils is typically higher than what crop plants need. The absence of a particular nutrient becomes a limiting factor in plant growth when the supply of that nutrient is exhausted.
Because of this, we add nutrients to the soil in the form of fertilizers, which feed the plants and make sure that there is never a shortage of any element required for a healthy crop production.

True: Climate mitigation involves both reducing emissions sources and increasing emissions sinks.
Climate change is one of the worst issues we are facing globally. Climate mitigation is one of the most effective measures to control this change. It involves reducing emission sources and increasing emission sinks so as to improve the situation. Climate change refers to the long-term changes in temperature and weather patterns. Although it may occur naturally, but is most probably caused by humans today. The emission of greenhouse gases is the primary source contributing to climate change, especially global warming. One of the most common greenhouse gas is Carbon dioxide which is released due to the emission of fuels, vehicles, reduced trees, etc.
We can control climate change by having two approaches: climate mitigation and adaptation. Reducing the emission of greenhouse gases in the atmosphere is referred to as climate mitigation. Adaptation refers to adapting to the climate change already persistent.
Climate mitigation involves reducing the release of heat-trapping greenhouse gases in the atmosphere, either by reducing the use of their sources like burning fossil fuels or by increasing the emission sinks that store these gases, such as rivers, forests, etc.
