Forces which do not require objects to physically touch are called _____. power forces action-at-a-distance forces contact forces non-contact forces
Answer:
Non contact forces
Explanation:
non-contact force is a force which acts on an object without coming physically in contact with it. The most familiar non-contact force is gravity, which confers weight. In contrast a contact force is a force applied to a body by another body that is in contact with it.

What would happen if Cyclin proteins did not function properly in the cell cycle?
Cyclin proteins are important in cell cycle progression; they partner with cyclin-dependent kinase enzymes to allow the cell cycle to progress. Without them, cell cycle progression would be hindered/stopped.
The situation when the cyclin proteins should not be function properly in the cell cycle because it is arrested.
What is Cyclin degradation?It is the key step that governs exit from mitosis and it should be progress into the coming cell cycle. It is equally vital with respect to the progression that arise from the cell cycle. In this, the particular enzymes should be split down cyclines at the particular time with respect to the cell cycle.
At the time when there is decrease in the cyclin levels so the CDK should not be inactive. Also, the cell cycle should be arrest at the time when the cyclines fail to degrade.

What conclusion about the effect of copper on plants is best supported by the information in the advertisement?
A.
Copper is absorbed and stored by the leaves, where it increases the rate at which pollen is produced.
B.
Copper is transported from the roots to the stem, where it slows the development of reproductive tissues.
C.
Copper is transported by the stem from the roots to the flowers, where it affects reproductive tissues.
D.
Copper is absorbed and stored by the roots, where it affects the development of eggs by the roots.
Answer:
D Copper is transported by the stem from the roots to the flowers, where it affects reproductive tissues.
Explanation:
Answer:
Copper is transported by the stem from the roots to the flowers, where it affects reproductive tissues.
Explanation:
i just had this question,
According to the advertisment, copper is essential for reproduction. So, it most likely affects a plant's reproductive structures, which are found within flowers. As Amazing Nutri-C is applied to the soil, the copper must be absorbed by the roots and then transported to these tissues by the stem of the plant.
Therefore, the conclusion that is best supported by the information in the advertisement is that copper is transported by the stem from the roots to the flowers, where it affects reproductive tissues.

Answer:
Igneous- relating to, resulting from, or suggestive of the intrusion or extrusion of magma or volcanic activity
metamorphic- describes a specific process that some rocks undergo when heat and pressure changes them.
extrusive- rock refers to the mode of igneous volcanic rock formation in which hot magma from inside the Earth flows out (extrudes) onto the surface as lava or explodes violently into the atmosphere to fall back as pyroclastics or tuff.

how do populations and communities affect one another?
Answer:
How can a change in one population affect the entire community in an ecosystem? If one population dies out, all the populations that depend on that species for food may also die out. A change in one population affects the entire community because all the populations of a community depend on each other.
Explanation:
Please can I get some help on this? please?
1. If the ecosystem is balanced, which populations should be the largest? Which should be the smallest?
2. Why can the wolf be considered both a secondary consumer and a tertiary consumer?
3. If the original amount of energy found in the producer trophic level is 100 kcal how much is passed on to the primary consumer trophic level? How does this amount limit the number of members in the next higher level?
4. Analyze what would happen to this ecosystem if one of the primary consumers was removed from the ecosystem? What would happen if a new tertiary consumer such as a mountain lion came into the ecosystem? Describe how each level would be affected if each of these changes occurred.
Answer:
1. producers are the largest and consumers are the least
2. because wolves feed on both primary and secondary consumers
3. Only 10% of energy from each trophic level is passed on to the next; therefore, the energy passed to the primary consumer will be only 10 kcal.
4. disturbe,as we know that secondary consumers feed on primary consumers so if there is no primary consumers then all secondary consumers will die similarly all tertiary consumers will also die and life would be finish on the earth.
if a new tertiary consumer came into the ecosystem then it will create a problem as the number of primary and secondary consumer are same but the tertiary consumer are more so they will get less food and hence die

What is a genotype?The whole complement of an organism's hereditary material is referred to as its genotype. An individual's alleles and variations that they carry in a specific gene or genetic region are also referred to as their genotype. Genotype is a term that may be used in both of these contexts.
The genetic make-up of an individual organism is referred to as its genotype. Your body's growth and development are guided by the information contained in your genotype, which acts like a set of instructions. When discussing the hereditary components of a certain characteristic, the term "genotype" is often used (like eye colour).
Therefore when you cross SS with ss the genotypes obtained are Ss, Ss, Ss and Ss.

describe how sugar is transported around a plant 6Marks
Answer:
Sugars move from “source” to “sink” ... Sugars produced in sources, such as leaves, need to be delivered to growing parts of the plant via the phloem in a process called translocation, or movement of sugar. The points of sugar delivery, such as roots, young shoots, and developing seeds, are called sinks.

The area of the cell that is associated with the production of ribosomes is the:
1. nucleolus
2. nucleus
3. nuclear pores
Answer:
Nucleolus
Explanation:
This is a more technical answer. The Nucleolus is located inside the nucleus and this is the location where the ribosomes are produced. They then leave through the nuclear pores to be sent out into the cell.
The area of the cell that is linked with production of ribosomes is nucleolus. The correct option is 1.
What is nucleolus?The nucleolus is a circular shape within the nucleus of cells that produces and assembles the cell's ribosomes. Ribosomal RNA genes are also transcribed in the nucleolus.
The nucleolus has the most visible realm in the nucleus of a eukaryotic cell, and its basic task is ribosomal RNA (rRNA) melding and ribosome biogenesis.
The nucleolus, as the site of ribosome biogenesis, is critical to cell metabolic activity.
It is made up of ribosomal DNA (rDNA), which is found in tandem arrays in nucleolus event coordinator regions.
The nucleolus synthesizes ribosomal subunits from proteins and ribosomal RNA, or rRNA.
It then starts sending the subunits to the rest of the cell, where they join together to form complete ribosomes.
Thus, the correct option is 1.
