Using the allele D to stand for a dominant sex-linked trait, show a cross with a woman who does not have a dominant sex-linked d

Mazyrski [523]

Answer:

There is no chance at all that the disorder carries out to their children that's if the woman has two dominant traits DD. If the woman has One dominant and one recessive Dd there is a 50% chance their kids may get the disorder.

in experiment 1, which of the following factors was systematically changed so that its effects could be observed? A.light intens

Stels [109]

Explanation:

<u>A.light intensity</u>

<u />

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Carbon dioxide + water + energy= glucose + oxygen

At the compensation point, the rate of CO2 production by respiration matches the rate of CO2 utilization in photosynthesis- there is no net CO2 production . Since photosynthesis is rate limited, the rate of energy intake can be reduced in order to reach the compensation point; lowering the light intensity would slow the rate of photolysis and thus photosynthesis. Similarly, an increase in light intensity

increases the rate of photosynthesis- the CO2 level would be reduced as more inorganic CO2 is fixed, together with producing O2 as waste.
would increase the temperature of the environment- light energy is converted to heat energy which increases temperature.
lead to higher levels of humidity- the heightened temperature increases the rate of evaporation of water from tissues, and thus increases the humidity (water vapor content of the surrounding air)

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

Occuring in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions and produces molecules of the energy storage molecule ATP through an electron transport chain. This occurs in the thykaloids, where pigment molecules like chlorophyll reside. Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules. These store energy in their bonds, which can be released in respiration in the mitochondria.

Describe the relationship between the sickle cell phenotype and hemoglobins structure and function.

galina1969 [7]

Answer:

It would be harder for the hemoglobin to move oxygen throughout the body because of how sickle cell looks/ its structure.

Sickle cell is a red blood cell but looks like a hook (in my opinion) while red blood cells are typically round, making them easier to transport in veins. due to the shape, it is harder for the blood to be transported.

However, when the proteins formed by the genes have their amino acids sequenced, there is no difference observed between the two

Musya8 [376]

Answer:

The correct answer is: Variation in nucleotide sequences are located in those regions of the gene which do not affect the sequence of the protein due to genetic code degeneracy.

Explanation:

Proteins are encoded from the genes located in the chromosomes.
The genes are made up of the heritable DNA (Deoxyribonucleic Acid) sequences.
These genes are transcribed by the enzyme called RNA polymerase into mRNA (messenger Ribonucleic Acid) sequences in the nucleus.
The mRNA is then translated into protein sequences by the Ribosome in the cytoplasm or the RER (Rough Endoplasmic Reticulum).
The Ribosome reads the mRNA code in form of triplets, that is, three consecutive nucleotide are read as a single code that encode for a single amino acid. This triplet code that responsible for coding for a single amino acid is called a Codon.
The Codons are degenerate in nature. This means that among the three nucleotide in a codon the first two nucleotide is specific for a particular amino acid. The third nucleotide is "wobble" in nature. This means that whatever may be the nucleotide in the third position it will not change the amino acid coded by the first two nucleotide.
Hence, a single amino acid is coded by more than one codon.
So, gene sequences showing variation in the wobble nucleotide position will encode for the same protein.
