The Punnett square above shows a cross between two sweet pea plants in Mendel's greenhouse. Both parents have purple flowers (Pp). Which statement describes the offspring expected from this cross?
A) 50% white-flowered and 50% purple-flowered
B) 75% white-flowered and 25% purple-flowered
C) 75% purple-flowered and 25% white-flowered
D) 100% purple-flowered and 0% white-flowered

Answers

Answer 1
Answer:

Answer: The correct answer is-

C) 75% purple-flowered and 25% white-flowered.

As per the information given in the question, genotypes of parent plants are-

Pp and Pp that is heterozygous dominant, which exhibit purple flowers.

This indicates that purple flower is a dominant trait that masks the expression of recessive trait.

A dominant trait ( depicted by capital letter allele) always masks the expression of recessive trait ( depicted by small letter allele).

When parent plants with heterozygous dominant ( having two different alleles that is dominant and recessive allele) genotype are crossed, they will produce 75% purple-flowered and 25% white-flowered plants.

Refer punnet square.

The clear protein of an egg white becomes opaque and firm when cooked because the heat

Answers

The clear protein of an egg become opaque and firm when cooked because the heat CHANGES THE PROTEIN STRUCTURE BY DENATURING THE PROTEIN.
Each enzymes has its own range of temperature at which it remains active, when this temperature is exceeded the protein becomes denatured and loses its three dimensional structure which determines its functions.

When environmental conditions are unfavorable, why is it an advantage for green algae to reproduce sexually? a. They are multicellular when conditions are unfavorable, which favors sexual reproduction.
b. Sexual reproduction produces larger numbers of offspring in less time.
c. Sexual reproduction produces offspring that have greater genetic variety and durable zygotes that can help green algae species survive unfavorable conditions.
d. Sexual reproduction produces multicellular algae instead of unicellular algae. Multicellular algae are better able to survive harsh conditions.

d. Sexual reproduction produces offspring that have a greater genetic variety and durable zygotes that can help green algae species survive unfavourable conditions.

_______________ is an abnormal episode of motor, sensory, autonomic, or psychic activity resulting from a sudden, abnormal, uncontrolled electrical discharge from cerebral neurons.

Answers

Answer:

Seizure is an abnormal episode of motor, sensory, autonomic, or psychic activity resulting from a sudden, abnormal, uncontrolled electrical discharge from cerebral neurons.

Explanation:

Seizure is also formally known as an epileptic seizure which it's symptoms involve uncontrolled body movements mostly with every part of the body and loss of consciousness. Epileptic seizure lasts for the maximum of two minutes before the person returns to a normal state. Bladder control however, is usually absent at this stage. Epileptic seizure can be caused by either provocation or without provocation

In provocation, the causes are very low blood sugar and blood sodium, severe fever, brain infection or concussion. Without provocation; brain injury or tumor and a stroke.

When a seizure lasts more than a maximum of two minutes, it is declared an emergency but some seizures do last for about five minutes and it is regarded as normal. There hasn't been any form of cure for epileptic seizures but there are temporary treatments which can prevent frequent seizures.

Answer:

Siezures

Explanation:

A seizure can simply be seen as a sudden, uncontrolled electrical disturbance in the brain. Seizures can cause involuntary muscular movements and behavioral changes. They can also affect levels of consciousness. Most seizures however, do not last very long. They usually last from 30 seconds to two minutes

Analyze the sentence to determine the main clause and the subordinate clause. Then choose the function of the subordinate clause.The Mason-Dixon Line, which is perhaps the most famous border ever established by surveying methods, has been designated a National Historic Civil Engineering Landmark.

1.​Main clause:
A.The Mason-Dixon Line
B.The Mason-Dixon Line, which is perhaps the most famous border ever established by surveying methods
C.The Mason-Dixon Line has been designated a National Historic Civil Engineering Landmark
D.the most famous border ever established by surveying methods has been designated a National Historic Civil Engineering Landmark
E.has been designated a National Historic Civil Engineering Landmark

2.Subordinate clause:
A.which is perhaps the most famous border ever established by surveying methods has been designated a National Historic Civil Engineering Landmark

3.Subordinate clause functions as a(n):
A.adjective
B.adverb
C.noun

Answers

1. The correct answer is C. The Mason- Dixon Line has been designed as a National Historic Civil Engineering Landmark.

Main clause can also be referred to as independent clause. There is a verb and a subject in it and they express a thought which is complete.

2. Correct answer is C. Which is perhaps the most famous border which is ever established by surveying methods.

Subordinate clause can also be known as dependent clause. It starts with relative pronoun and it has both verb and subject. A complete sentence can not be formed in this combination.

3. The correct answer is adjective.

Subordinate clause functions the same way as adjective.
