Answer: d) It would only survive in areas farther away from the vents at lower temperatures.
Explanation: Staphylothermus marinus is an anaerobic hetereotrophs that thrives in extremely hot environments with temperatures ranging from 85°c - 92°c when the nutrient concentration low and 98°c at a when the nutrient concentration is high thereby making them hyperthermophiles.
Habitat loss is contributing to the permanent loss of species, the weakening of ecosystems, and is impacting the overall health of the planet.
Example:
While tree-clearing is a significant cause of habitat loss in Australia, other major contributing factors include altered bushfire frequency and the introduction of pest species that make habitats unsafe for native species or outcompete them. Meanwhile, on the Great Barrier Reef, the impacts of human-induced climate change are altering the habitats of corals, leading to large-scale coral bleaching. Over time, destruction of such habitats leads to reduced biodiversity and weakening of the Earth’s ecosystem.
It would be D. Water molecules are split apart and the byproduct of that would be the O2. As energy enters the chloroplasts, the energy excited the H2O molecules and causes them to split
Question in English:
A female carries a recessive lethal gene (l) on one of her X chromosomes, and a normal dominant allele (L) on the other. What is the sex ratio to be expected in this woman's dependency if she marries a normal man?
Answer:
2/3 females
1/3 males
Explanation:
Females have two X chromosomes (XX) and males have an X and a Y chromosome (XY).
The genotype of the female is XLXl. The genotype of the male is XLY, since he is normal.
The possible genotypes are:
<u> XL Xl</u>
<u>XL</u> <em>XLXL XLXl</em>
<u>Y</u> <em>XLY </em><em>XlY</em>
<em />
All female offspring will be normal as they will always have one normal copy of the X chromosome from their father.
50% of the male offspring will be normal, but 50% will inherit the lethal gene from their mother.
Because the allele is lethal, that means XlY males will not be born.
That means 2/3 of the children will be females, and 1/3 will be males.
