Answer:
measure of the intrinsic luminosity of a celestial body (such as a star) expressed as the apparent magnitude the body would have if viewed from a distance of 10 parsecs.
Explanation:
<span>F- allele for freckles
f- </span><span>allele without freckles
1) The man is heterozygote and has freckles, its indicating that the allele for freckles is dominant.
A cross between him and a woman who is also </span><span>heterozygote: Ff x Ff
it would result in the following probabilities:
- 1/4 - homozygote with freckles: FF
- 2/4 - </span><span>heterozygote with freckles: Ff
- 1/4- </span><span>homozygote without freckles:ff
Their son would have a probability of 75% of being born with freckles.
2) The cross resulted in this probabilities:
</span><span><span>- 1/4 - homozygote with freckles: FF
- 2/4 - </span><span>heterozygote with freckles: Ff
- 1/4- </span><span>homozygote without freckles:ff
So, the chance of being born heterozygote for this gene is 2/4, which is the same as half (50%).

<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.

The two sources of information used to direct the expression of genes during various stages of development are Transcription and Translation.
<h3><u>Explanation:</u></h3>
Both of them combined is called gene expression.Transcription is the process of sharing information stored in a DNA to RNA.
The process of translation is carried out in cytoplasm. Here, the mRNA, in which stands for messenger, send messages to a more complex and specialized molecule called the ribosome. The sequence present on the mRNA base is read by the ribosome.
Transcription takes place in nucleus and translation takes place in Cytoplasam. The products of transcription are mRNA, tRNA, rRNA. The products of translation are Proteins.
Answer:
to cross the plasma membrane.
Explanation:
Two classes of proteins that mediate facilitated diffusion are generally distinguished: carrier proteins and channel proteins.
