A man with blood type B marries a woman with blood type A . Their first child has blood type 0 . Use a Punnett square to predict what other blood types are possible for their offspring .

Answers

Answer:

They have 1:4 chances of 0, 1:4 cahnces of AB, 1:4 chances of A, 1:4 chances of B

Explanation:

Blood has three types of alleles: A, B, 0 depending on the type of proteins in blood cells. They can have protein A, B, or not having them 0. The dominant allele will be B or A.

All types of blood are A, B, AB (co-dominance) and 0.

We all have two alleles for each gene, one comes from our mother, and one comes from our father.

If both parents are dominant, but they have a recessive child, you have both heterozygote genes to do the Punnett square.

Mother: I(A)i(0)

Father: I(B)i(0)
The punnett square is attached to this.
The other possibilities are AB, BO, and AO. 
All of them have 25%.

In the past, an irregular heart rhythm was treated by using a drug to help regulate the beat. There is a treatment that can also regulate heart rhythms that has replaced drugs in some cases. What is that treatment?A. pacemaker

B. angioplasty

C. clot-dissolving drugs

D. myocardial infarction

Answers

The pacemakers are implants that are used for the regulation of heartbeats (correction of irregular heartbeats).

It is a small device, implanted (minor surgical procedure) just under the skin of the chest, that sends electrical impulses to the heart muscle to maintain a suitable heart rate and rhythm.

 

The pacemaker has two parts:

·         the leads which are threaded through the veins into the heart and implanted into the heart muscle. They send impulses from the pulse generator to the heart muscle. There can be one or more leads depending on the type of the heart problem

·         a pulse generator which contains the battery and a tiny computer and resides just under the skin of the chest.

Each impulse causes the heart to contract. A pacemaker may also be used to treat different heart issues such as fainting spells (syncope), congestive heart failure, and hypertrophic cardiomyopathy.

A light microscope that makes the specimen appear light on a dark background is called a(n) _____.

Answers

A light microscope that makes the specimen appear light on a dark background is called a compound microscope. Compound microscope accomplishes more elevated amounts of amplification than a stereo or low power magnifying lens. It is utilized to see littler examples, for example, cell structures which can't be seen at lower levels of amplification. Basically, a compound magnifying lens comprises of auxiliary and optical segments.

The correct answer is Dark-field microscope.
