What wavelength pf visible light do the hottest stars emit?

Biology

vlabodo [156]3 years ago
5 0

Answer:

Hot stars, meaning those having surface temperatures in excess of 10,000 K (vs ∼5800 K for our sun), emit much or most of their radiation in the UV wavelength range below 300 nm, the limit for ground-based observations.

How can the Geosphere affect the atmosphere
Zolol [24]
The correct option is C.
The geosphere refers to the solid parts of the earth. All of these parts are affected when a volcanic eruption occur. When volcanic eruption occurs, it contributes to the greenhouse effect in the atmosphere because carbon dioxide which is regarded as a greenhouse gas is released into the atmosphere. Also sulphur dioxide gas is released which results in acid rain.

In pigs, curly tails (T) are dominant over straight tails (t). If a pig is heterozygous for a curly tail, what is the pig's geno
n200080 [17]

Answer:

The pig's genotype is Tt

Explanation:

As mentioned in the question that curly hair allele T is dominant over straight tail allele t.

A heterozygous organism is that in which both alleles for a trait are different. Since Curly hair allele T is dominant over straight tail t, it means that the pig with curly tail and heterozygous genotype will definitely have a genotype of Tt.

Hope it helps! :)

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.
