Anaerobes carry on whereas aerobes carry on cellular respiration

Tcecarenko [31]

Answer:

Anaerobes carry on cellular respiration in the absence of oxygen, whereas aerobes carry on cellular respiration in the presence of oxygen.

Explanation:

Many of the cell processes needed need some energy to occur. Cellular respiration is the process by which cells degrade organic compounds and turn them into energy. Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.

Aerobic Respiration

Occurs in the presence of free oxygen.
Series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules.
Respiration occurs in the mitochondria.
Takes place in two steps or stages: Krebs cycle and electron transporter chain.
Glycolysis and Krebs cycle produce electrons, which then travel along the electron transporter chain while releasing energy, and ATP is produced.

Anaerobic Respiration

Occurs in the absence of free oxygen
Series of reactions by which using pyruvate (product of glycolysis) 2 ATP molecules van be produced.
There are two ways in which anaerobic respiration can be produced: lactic fermentation and alcoholic fermentation.
Lactic fermentation produces lactic acid and 2 ATP
Alcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂
The whole anaerobic process occurs outside the mitochondria.

A new human species was found on a distant planet, whose genetic inheritance and process of reproduction is identical to that of

Vedmedyk [2.9K]

Answer:

E/e ; T/t ⇒ Square eyes and long tail (Option D)
3/16 will have round eyes and long tails (Option C)
1/4 of the progeny will be heterozygous for both traits (Option A)

Explanation:

Available data:

Two diallelic unlinked genes
Gene E controls eye shape: Dominant allele E expresses square eyes, and recessive allele e expresses round eyes.
Gene T controls the tail size. Dominant allele T expresses long trail, and recessive allele t expresses short tail.

Genotypes Phenotypes

EETT, EeTT, EETt, EeTt Square eyes and Long tail

eeTT, eeTt Round eyes and Long tail

EEtt, Eett Square eyes and Short tail

eett Rounf eyes and short tail.

1. An individual of this new species is heterozygous for gene E and heterozygous for gene T. What is their genotype and phenotype?

The heterozygous individual is E/e ; T/t, expressing square eyes and a long tail.

2. Two individuals, who are both heterozygous for eye shape and tail size, mate. Which of the following is a correct statement about the phenotype ratios expected for their offspring?

Cross: between two heterozygous individuals

F1) Genotype:

1/16 EETT
2/16 EETt
1/16 EEtt
2/16 EeTT
4/16 EeTt ⇒ 1/4 EeTt
2/16 Eett
1/16 eeTT
2/16 eeTt
1/16 eett

Phenotype

9/16 E-T-, Square eyes and Long tails
3/16 E-tt, Square eyes and short tails
3/16 eeT-, Round eyes and Long tails
1/16 eett, round eyes and short tail

Phenotypic ratio 9:3:3:1

3. From the mating described in question ABOVE, what proportion of ALL of the offspring in will be heterozygous for both traits?

4/16 = 1/4 = 25% of the progeny are expected to be heterozygous for both traits, EeTt.

zmey [24]

Answer:

In which class of elements is there a greater range of properties, the metals or the nonmetals? Give an example to support your answer. Non-metals have greater range of properties given that they exist as solids, liquids and gases. And also that they can polymerize, crystallize and form organic compounds.
