How many paths through which charge can flow would be shown in a circuit diagram of a parallel circuit? more information is need

Tasya [4]

Answer: More than 1

Explanation:

A parallel circuit is defined by having more than one path through which current can flow. This is in contrast to a Series circuit where the current flows through just one path.

Even though there are multiple paths for the current to flow through, the current flowing through all the paths must add up to the total current that is being supplied from the source.

To check whether Earnest and Denise could have a baby with Type O blood, draw a Punnett square for a father who has blood Type A

Nutka1998 [239]

Answer:

Answer is explained below and also see the document attached below for Punnett square.

Explanation:

ABO blood type (A, B, AB, or O) is based on the presence (or absence) of the A and B antigens in the red blood cells. The blood type, A has only the A antigen (and has anti-B antibodies) while the blood type, B has only the B antigen (and had anti-A antibodies). Also in the AB blood type, both A and B antigens are present (but has no antibodies) while in the O blood type, both A and B antigens are absent (but has both antibodies).

The blood type is inherited from the parents and the offspring inherits one of the two alleles from each parent. The ABO blood type has three types of alleles: IA, IB, and i. Here, I is a term for antigen (isoagglutinogen).

The IA and IB alleles are dominant while the i allele is recessive. The blood type A is formed by either two IA alleles (IA IA ) or IA i. So, the genotype of blood type A is IA IA or IA i. The blood type B is formed by either two IB alleles (IB IB ) or IB i. So, the genotype of blood type B is IB IB or IB i. The O blood type is formed only by two i alleles (ii). So, the genotype of blood type O is ii. The IA and IB alleles (IA IB) give the AB blood type, which is an example of codominance (the traits of both the alleles are visible in the phenotype). The genotype of blood type AB is IA IB.

If the parents have blood type A and B, then they can have an AB blood type offspring. If the parents have blood type A and B and they both are heterozygous (IB i and IA i), then they can also have a O blood type child.

Here, the father has blood Type A (IA i genotype) while the mother has blood Type B (IB i genotype). Both the parents are heterozygous (IB i and IAi), so the possible genotypes of their child are IA IB (blood type AB), IA i (blood type A), IB i (blood type B) and ii (blood type O).

i.e., <u> Blood Type </u> <u>Genotype </u>

A IA IA or IA i

B IB IB or IB i

AB IA IB

O ii

What cell feature is used by scientists to classify an unknown cell as prokaryotic or eukaryotic?

zhannawk [14.2K]

Answer:

Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions.

Explanation:

Hope this helps ;)

Muscle cell activity increases and ATP decreases below the set-point, a sensor molecule detects low ATP and activates protein ki

sergeinik [125]

Answer: Feedback mechanism

Explanation:

Feedback mechanism is the body's way of maintaining physiologic processes in the body. These physiologic processes include maintaining homeostasis, production of energy, hormones as well as enzymes required for chemical reactions.

There are 2 types of feedback mechanism:

Positive feedback: The stimulus (message) sent to the brain, produces prolonged increased production or increased activity in the body.
Negative feedback: In negative feedback, the stimulus causes production, secretion or activity till a set point where the body knows it has taken enough. This causes a self termination of the process.

In the increased muscle activity, the increase in activity in turn causes a decrease in energy (ATP) and serves as the stimulus leading to the release of enzymes which in turn lead to increased absorption of glucose which will be used by the body to produce more ATP needed for the muscular activity. At the end of the muscular activity, the body recognizes that it doesn't need an increased absorption of glucose to support increased activity anymore and glucose absorption normalizes.
