Which conclusion is supported by this evidence? Neither ball has a charge. The balls are both positively charged. One ball is positively charged, and the other is negatively charged. Each ball has a charge, but the type of charge is unknown.
Answer:
The correct answer is - Neither ball has a charge
Explanation:
If the two balls are hanged near one another without touch or an external charge to any of the balls there would be no charge present. In the given question is it given that two balls hang down without any contact in them.
So there is no possible way to generate charge and remain uncharge in their position till they get any external charge.
The correct answer is - Neither ball has a charge

Some people have one sickle cell gene and one normal gene. They have few defective cells and no symptoms because the sickle cell gene is recessive. How does the human system of reproduction result in people getting one copy of a sickle cell gene and one copy of a normal gene? Describe the process.
Answer:
Through meiosis
Please find the description below
Explanation:
Humans reproduce via a type of reproduction called SEXUAL REPRODUCTION. Sexual reproduction is the type of reproduction that involves two sexes (male and female) of an organism. The males produces male gametes called SPERM while females produce female gametes called EGG.
The process by which these gametes is produced is called MEIOSIS. Meiosis is a division that reduces the chromosome number of the parent cells. According to Gregor Mendel, it occurs in such a way only one allele of a gene is present in each gamete.
Hence, according to this question, getting one copy of a sickle cell gene and one copy of a normal gene is as a result of meiotic division of male and female. One parent undergoes meiosis and contributes the normal allele (S) while the other parent undergoes meiosis and contribute the sickle allele (s).
Your lab is working on sequencing a new plasmid. Before starting, you all decide to guess how many base pairs you think the new plasmid has. The lab members' guesses are 4,005; 4,006; 4,007; and 4,010. It turns out the plasmid has 7,968 base pairs. Accurate Precise Neither Both
Solution :
In this question we have to determine whether the statement given in the question is accurate or precise or both or neither of them.
In the question it is given that the lab members are making a guess about how many base pairs will the new plasmid will have. Their random guesses of base pairs are 4,005; 4,006; 4,007; and 4,010. But in actual, the new plasmid has 7,968 number of base pairs.
Therefore, according to it, the data in the statement is precise but it is not accurate.
Precision refers to the degree of the reproducibility of measurements even if the values varies from accepted values. And accuracy shows how much close the measurement is to the accepted or the known value.
We say that we have a precise data on our hands and not an accurate one
Option B
AccuracyQuestion Parameters:
The lab members' guesses are 4,005; 4,006; 4,007; and 4,010.
Generally, accuracy shows how close a size is to a regarded or established value, whilst precision in facts capability the degree of reproducibility of the measurements. Measurements that are each specific and correct are repeatable and very close to genuine values.
Hence, we say that we have a precise data on our hands and not an accurate one

How does a bird develop?
Answer:
All birds start their lives inside an egg. When some birds hatch from the egg they are covered in downy feathers, and they are able to run around and find their own food. Many ground-living birds, such as pheasants and ducks, develop in this way.

Primary producers are the basis of any food chain. Sunlight powers photosynthesis which results in the production of chemical energy, glucose. Some organisms are known to survive in dark habits in which sunlight cannot penetrate. What process is responsible for how these organisms obtain energy? A) chemosynthesis B) photosynthesis C) Spermatogenesis D) Cellular respiration
Answer:
A) Chemosynthesis
Explanation:
Organisms, such as bacteria and other living organisms, use chemosynthesis when there is an absence of light. They use inorganic chemicals to produce energy through reactions.

What would be the correct complimentary DNA strand given the following DNA strand.
DNA: ATACGAAAT (Type as one word - no spaces)
Using the same strand of DNA, what would be the correct sequence for an RNA strand? (Type as one word - no spaces)
Answer:
TATGCTTTA for question 1.
For RNA following the original strand it would be UAUGCUUUA
Explanation:
Replace A with T(vice versa), and C with G(vice versa)
But for the RNA, A bonds with U instead of T. So it would be the same as the complimentary DNA, just with U instead of T
The chromosome number in animas is kept the same from one generation to the next because of__.
Answer:
Mitosis
Explanation:
Mitosis is the process of cell division. In this process cells are split to create exact replicas of eachother. It is why we don't grow ears on our hands when they are injured. The hand cells are replicated to create more, so it heals correctly. In the Mitosis the two resulting daughter cells always have the same number of chromosomes from the parent cell. Their role is to maintain the same number of chromosomes in each cell division constant, which allows us to grow and self-maintain our bodies.
how are energy and matter transferred between organisms and their environment
Answer:
The energy is transferred both to the decomposer (for growth and development) and to the ecosystem (as heat energy).
Explanation:
Answer:
Food webs are models that demonstrate how matter and energy is transferred between producers, consumers, and decomposers as the three groups interact within an ecosystem. ... Decomposers recycle nutrients from dead plant or animal matter back to the soil in terrestrial environments or to the water in aquatic environments.
