1) Color blindness is a trait that is carried on the X chromosome. Perform a cross between the following parents: a) A woman who has normal vision but whose father was colorblind. b) A man who is colorblind
2) If these individuals have exactly four children together, what number of children would you expect to be male, female, colorblind, and not colorblind?

Answer:

36 individuals xxyyzz

Explanation:

Available data:

We need to know how many individuals from the F2 are going to be xxyyzz

xxyyzz genotype is the result of a double recombinant event.

First, we need to analyze the given information:

→ Distances between genes

The genetic distance result from multiplying the recombination frequency of each region by 100 and expressing it in map units (MU). So, if we have the genetic distance we can divide it by 100 and get the recombination frequency:

Let us say that region I is the distance between X and Y. And region II is the distance between Y and Z.

GD = genetic distance

RF = Recombination frequency

20MU = RF x 100

20MU/100 = RF

0.2 = RF (Region I)

30MU = RF x 100

30MU/100 = RF

0.3 = RF (Region II)      

Now we have the recombination frequency of Region I and Region II.

→ Interference    

Knowing the interference value will let us know the value of the coefficient of coincidence, which will also lead us to the number of individuals xxyyzz.

I = 40%

I = 1 - CC   ⇒ CC = coefficient of coincidence

Clearing this equation gives us the value of CC

CC = 1 - I

CC = 1 - 40% = 1 - 0.4

CC = 0.6

To calculate the coefficient of coincidence, CC, we can also use the next formula:

CC = observed double recombinant frequency/expected double recombinant frequency

Now, we are interested in knowing the value of the observed double recombinant frequency.

Note:  

So, to get the value of the observed double recombinant frequency, first, we need to get the value of the expected double recombinant frequency. And we can do it because we already have the recombination frequencies in both regions.

expected double recombinant frequency = recombination frequency in region I x recombination frequency in region II

- Recombination Frequency - RI = 0.2

- Recombination Frequency  - RII = 0.3

expected double recombinant frequency = 0.2 x 0.3

expected double recombinant frequency = 0.06 = EDRF

Now that we know the value of the CC and the expected DRF, we can get the observed double recombinant frequency.

CC = observed double recombinant frequency/expected double recombinant frequency

- CC = 0.6

- EDRF = 0.06

CC x expected double recombinant frequency = observed double recombinant frequency

0.6 x 0.06 = observed double recombinant frequency

0.036 = observed double recombinant frequency = ODRF

Finally, as this is a frequency, we need to multiply it by the total number of individuals in the F2 to get the number of observed double recombinant individuals.

- ODRF = 0.036

- N = 1000

Double recombinant individuals = 0.036 x 1000 = 36 individuals xxyyzz.

16. should be B) Chemical Properties of Water.

Because those are all examples of chemical changes of water.

17. should be B) The liquid will remain a liquid.

Because 52° C is the same as 125.6° F.

Answer: Atmospheric gases, especially carbon dioxide (CO2) and oxygen (O2), are extremely important for living organisms. Carbon dioxide and oxygen are the gases in the atmosphere that are needed for life. Plants need carbon dioxide for photosynthesis. They use sunlight to change carbon dioxide and water into food. The process releases oxygen

Answer:

true

Explanation:

Explanation: In the open water zone (or photic zone) sunlight supports photosynthetic algae and the species that feed upon them. In the deep water zone, sunlight is not available and the food web is based on detritus entering from the littoral and photic zones.

Answer:

the hydroxide ions are undergoing ionization and the particles are gaining / losing electrons .

Explanation:

i think it is because ::

the phenolphthalein of the solution has gone from having a pH of around 8 (pink) to being alkaline at above 10 which causes it to burn purple / violet .

Answer:

Explanation:

Types of learning include habituation, sensitization, classical conditioning, operant conditioning, observational learning, play, and insight learning. One of the simplest ways that animals learn is through habituation, where animals decrease the frequency of the behavior in response to a repeated stimulus.

Explanation:

Edge 2021

Answer:

D- The total number of atoms when glucose and oxygen react stays the same when carbon dioxide and water are produced.

Explanation:

The conservation of mass during cellular respiration can be explained by the fact that after cellular respiration which occurs due to the oxidation of glucose to produce carbon dioxide and water, the number of atoms on the right hand side (RHS) of the reaction remain same as of left hand side (LHS) of the reaction.

The balanced chemical equation is mentioned as under:

C₆H₁₂O₆  +     6 O₂         ->     6 CO₂       +      6H₂O    +     Energy.

(Glucose)     (Oxygen)          (Carbon            (Water)

                                              dioxide)

If we will see carefully, the number of atoms of each element on RHS & LHS of the equation are same i.e. there are 6 atoms of C, 18 atoms of O and 12 atoms of H on both the sides.

Answer:

12. A

13. A

Explanation:

12. A chemical reaction occurs when something new is transformed and changed chemically. The other answer choices, B, C, and D are physical changes; nothing new is really being created.

13. When water is heated to become a gas, that term is called boiling. Hence the name, boiling point.

Answer:

Jupiter, Saturn, Uranus, and Neptune

Explanation:

Answer:

Some researchers classify Australopithecines into gracile australopithecines and robust australopithecines, while others argue that differences are enough strong to classify robust australopithecines in their own genus called 'Paranthropus'. In my opinion, it seems reasonable to obtain more fossil data in order to support this division  

Explanation:

The term Australopithecines comes from the genus Australopithecus, which are the closest known relatives of our genus Homo, and arose around three (3) million years ago. Australopithecines can be classified into two major groups called gracile australopithecines and robust australopithecines. However, robust australopithecines have also been classified in their own genus, Paranthropus, in order to distinguish them from the gracile australopithecines. The major differences between gracile and robust species are associated with facial and cranial features. Paranthropus species had a large sagittal crest, enormous cheek teeth, robust jaws, and strong jaw muscles (suggesting they were herbivores that ate tough food). However, these main features may not be conclusive evidence that supports the separation of Paranthropus in its own clade, thereby in my opinion it should be reasonable to wait until more fossils are found in order ​to correctly classify Paranthropus species as a different group.

Answer:tissue

Explanation:

Tissues are groups of cells that have a similar structure and act together to perform a specific function. The word tissue comes from a form of an old French verb meaning “to weave”. ... Groups of tissues make up organs in the body such as the brain and heart.

Answer:

It increases for most species.

Answer: (c) can undergo self-renewing divisions for the lifetime of a healthy animal.

Explanation:

The adult hematopoietic tissue or adult hematopoietic stem cells can be found in bone marrow of the animal. These cells have the ability to regenerate and renew so that the production of red blood cells remains continuous till death. Hematopoiesis can be defined as the production of cellular components of blood. The adult hematopoietic stem cells are located in the flat bones and ends of the long bones.
