5 0

Two ways scientist Can describe the quality of measurements are (examples down below)
•The length of a piece of string can be measured by comparing the string against a meter stick.
•The volume of a drop of water may be measured using a graduated cylinder.
•The mass of a sample may be measured using a scale or balance.
•The temperature of a fire may be measured using a thermocouple.

Donor Blood Type Recipient Blood Type A- Successful

tekilochka [14]

Answer:

The first blood transfusion in which the donor blood type is A+ and recipient blood type is A- would not be successful as the donor blood is A+, which signifies that the blood comprises both Rh factor and antigen A, while the recipient blood group is A-, which signifies that the blood does not comprise Rh factor and possess only antigen A. Therefore, at the time of transfusion, the Rh factor of donor blood will be regarded as a foreign body by the recipient, and thus, will generate antibody against the donor Rh factor provoking immune rejection and agglutination.

On the other hand, the second blood transfusion in which the donor blood type is O- and the recipient blood type is AB+, the blood transfusion would be successful as the blood group O- is a universal donor, as it neither possesses any A or B antigen nor Rh factor. This blood group is accepted by all the blood group recipients.

At the official announcement of completion of the draft human genome (choose all that apply)

In-s [12.5K]

Answer:

(B) Two alternative strategies were used to complete the genome - top down and bottom up
(C) The public project used a mapping strategy to limit the total sequencing required
(D) The Celera group, led by Craig Venter, used a shot gun sequencing strategy

Explanation:

As the project was unable to sequence all the DNA that was found in the human cells, the first draft was <u>made in June and complete in the end referred to as a working draft and made on the basis of the final sequencing and mapping of the human genome. </u>

The <u>draft included the alternative strategies for the completion of the bottom up and top up of the genome code and has a mapping strategy</u> that limited the total sequencing needs.

Long legs (L) in racing horses is dominant to short legs (l). Good muscle tone (G) is dominant to weak muscle tone (g). Determin

vova2212 [387]

Answer:

See the answer below

Explanation:

Long leg (L) is dominant over short leg (l) and Good muscles (G) is dominant over weak muscles (g).

Heterozygous long leg, weak muscle = Llgg

Heterozygous long leg, strong muscle = LlGg

Llgg x LlGg

Offspring:

2 LLGg - Long leg, strong muscle

4 LlGg - Long leg, strong muscle

2 LLgg - Long leg, weak muscle

4 Llgg - long leg, weak muscle

2 llGg - short leg, strong muscle

2 llgg - short leg, weak muscle

Ratio of offspring with long leg and strong muscle = 6/16 or 3/8

Ratio of offspring with long leg and weak muscle = 6/16 or 3/8

Ratio of offspring with short leg and strong muscle = 2/16 or 1/8

Ratio of offspring with short leg and weak muscle = 2/16 or 1/8
