Answer:
(a) 1/2; (b) no
Explanation:
Glucose-6-phosphate dehydrogenase deficiency (G6PD) is an X-linked recessive disorder and the woman's father was diseased so it means that woman is a carrier of the allele but has normal phenotype. It means that she will have XXᵇ genotype.
In contrast to this, her husband is diseased so his genotype will be XᵇY.
The Punnett square diagram related to the cross is attached.
(a) Proportion of their sons expected to be G6PD is 1/2:
They both may give birth to 4 progeny with genotypes XXᵇ, XᵇXᵇ, XY and XᵇY. It means they both may have 2 sons out of which one with genotype XᵇY will be diseased while the one with genotype XY will be healthy. So the proportion of their sons having G6PD is 1/2 or 50%.
(b) If the husband were G6PD deficient, the answer will not change.
The reason behind this is that this disease is caused by an allele located in X chromosome. But father contributes only Y chromosome to his son not X chromosome. The X chromosome will affect the genotype of his daughter not son that is why answer will not change. It means they will still have 1/2 of their sons diseased.
Endomembrane system -- not in prokaryotes
cytoskeleton -- a structural part of cytoplasm sometimes occurrent in prokaryotes
mitochondria -- not in prokaryotes
nucleus -- if this is a "membrane-bound" nucleus, then definitely not in prokaryotes
cytoplasm -- this is the fluid that houses everything in the cell membrane
flagella -- little "tail" for locomotion, so no
cilia -- similar to flagella, little feelers usually for locomotion
ribosomes -- these make protein using amino acids
chloroplasts -- not in prokaryotes
membrane -- just a casing surrounding a cell or organelle
organelles -- general word for the parts of a cell that perform various functions
cell membrane -- just the casing for the cell, not where genetic material's located
<span>nucleoid --- ding ding ding :-) this is it; a nucleoid is the genetic material which is loosely existing in the cytoplasm of a prokaryotic cell</span>
Most macteria canot grow well in acid fluids like pickle juice. so its the combination of salt and acid. as for fungi, i can only guess..... many bacteria dont grow well if the temperature is coldish or if the conditiones are very salty or sugary
Answer:
Avoid fragmenting the forest by building the new homes together on one side of the forest
Explanation:
<em>Fragmentation of forest involves breaking of large continuous forests into smaller, ecologically less diverse units</em>. This often happen as a result of human factors such as road construction, agriculture, building construction, and so on.
Forest fragmentation has several effects including, reduction in forest's health, degradation of habitats loss of biodiversity, among others.
Hence, the best mode of action is for the urban planner to build the homes clustered together on one side of the forest to avoid fragmenting the forest.
Answer:
It adapts to the changing climate
Explanation:
Species have to acclimatise to changing climate to enable them survive
A means of adaptation is key for survival of species during climate change
If species do not have acclimatisation strategy, they would not be able to survive the changing climate
