D. The planet's orbital path will become smaller and its orbital period will increase.

The more gravity an object has, the more it will pull objects.

Answer:

The correct answer will be option D.

Explanation:

Planets orbit around the Sun (star) due to the gravity of this star which pulls down them around it. This gravity is the vital force which maintains the elliptical path of their orbit.

If this force of gravity will change it will affect the celestial bodies revolving around it like a planet as this force of gravity is directly proportional to mass and inversely proportional to the distance between them.

According to the question if the gravity of the star increases it will change the orbital path of the planets as they will be more pulled towards the sun which will decrease the distance between the star and planet and the orbital path will become smaller and the orbital period will increase.

Thus, option D is the correct answer.

What are the three types of anthrax infection (prior to 2010, when a fourth type was added)? Describe each type.
Westkost [7]

Answer:

1) Cutaneous Anthrax

2) Inhalation Anthrax

3) gastrointestinal anthrax

Explanation:

The four types of Anthrax infection are:

1) Cutaneous Anthrax - In this type of anthrax, red spot is raised on the skin which increase with redness around it. The symptoms of this include headache, fever, vomiting, etc

2) Inhalation Anthrax - the symptoms of this type of anthrax include, headaches, flu, respiratory problem, coma, and severe cases death.

3) gastrointestinal anthrax - this cause due to the eating of contaminated meat which results in nausea,  diarrhea, abdominal pain, etc.

4.4-1 Anaerobic Respiration
Vesna [10]

For lactic acid fermentation, the correct options are:

  • pyruvate
  • hydrogen
  • NADH
  • lactic acid
  • Lactic acid
  • pyruvate
  • mitochondria

For ethanol fermentation, the correct options are:

  • pyruvate
  • CO₂
  • acetyl CoA
  • acetyl CoA
  • acetaldehyde
  • Acetaldehyde
  • hydrogen
  • NADH
  • ethanol

<h3>What is a anaerobic respiration?</h3>

Anaerobic respiration is respiration which occurs in the absence of oxygen.

Oxygen is used as an electron acceptor during respiration. However, when oxygen is absent or insufficient, other molecules are used as electron acceptors in order to produce energy.

Anaerobic respiration in large organisms may result in the formation of lactate known as lactic acid fermentation.

In lactic acid fermentation, after glycolysis, the two pyruvate molecules receive hydrogen atoms from NADH creating lactic acid. Lactic acid can be converted back into pyruvate in the liver. The pyruvate can then enter into the mitochondria and cellular respiration, can proceed.

On the other hand, anaerobic respiration in microorganisms produce ethanol and is known as ethanol fermentation.

After glycolysis, the two pyruvate molecules lose a CO₂ atom, creating acetyl CoA. The acetyl CoA atom combines with hydrogen to form acetaldehyde. Acetaldehyde receives a hydrogen atom from NADH, resulting in the production of ethanol.

In conclusion, anaerobic respiration can occur either as a lactate fermentation or ethanol fermentation.
