Describe the pattern of inheritance that is most likely associated with a mutation in the MT-ND5 gene. Explain why individuals are not typically heterozygous with respect to mitochondrial genes.
Answer:
this gene is a mitochondrial gene and therefore it is maternally inherited
Explanation:
The MT-ND5 gene is a gene of the mitochondrial genome that provides instructions for synthesizing a protein called NADH dehydrogenase 5, which is part of the complex I (the first enzyme of the respiratory chain). In most multicellular organisms, the mitochondrial DNA (mtDNA) is inherited from the mother (i.e., maternally inherited), whereas nuclear DNA (i.e., nuclear genome) is inherited equally from both parents. For example, mitochondria in human sperm are usually destroyed after fertilization. In consequence, mitochondrial mutations are transmitted by maternal inheritance, and individuals, therefore, cannot be heterozygous for mitochondrial genes.
The pattern of inheritance that is most likely associated with a mutation in the MT-ND5 gene is
MT-ND5 is a mitochondrial genome coded gene responsible for the protein NADH-ubiquinone oxidoreductase chain V protein (ND5). ND5 is a sub-unit od NADH dehydrogenase, a mitochondrial protein. The mutant MT-ND5 will be transferred to the progeny via maternal mitochodral mtDNA.Individuals are not typically heterozygous with respect to mitochondrial genes because
Heterozygousity of alleles of a particular gene arises due to contribution of both maternal and paternal genes. This is what happens for nuclear chromosomes. Mitochondria is an organelle that contains its independent genome. Only maternal mitochondria gets selected and thus are successfully transferred to the next generation post fertilization.For more information on MT-ND5 gene

an asteroid impact.
lower levels of carbon dioxide in the air.
bacteria producing large amounts of toxic methane.
algae consuming too much oxygen from the ocean.
The “great dying,” which saw 96% of all species extinct, was partially caused by an asteroid impact. So, the correct option is A.
What do you mean by Species?Species may be defined as a group of organisms that can reproduce with one another in nature and produce fertile offspring.
An asteroid impact threatens the whole biodiversity to a large extent. It leads to the destruction of almost all life forms living on the earth's surface.
Therefore, the “great dying,” which saw 96% of all species extinct, was partially caused by an asteroid impact.

How can you apply this approach to the classification of living things?
Answer:
Living things are classified into groups that start out large and become more specific in a system of classification called taxonomy. Scientists classify living things at eight different levels: domain, kingdom, phylum, class, order, family, genus, and species.

Why is it more difficult for top carnivores to obtain sufficient energy resources than it is for animals lower on the food chain?
the trophic pyramid is the reason
what the trophic pyramid is: Trophic pyramid, also called an energy pyramid, showing the progression of food energy. The pyramid base contains producers, organisms that make their own food from inorganic substances. All other organisms in the pyramid are consumers
- predators get little energy from the prey they eat so they must consume multiple prey
It is more difficult for top carnivores to obtain sufficient energy resources than it is for animals lower on the food chain because the higher trophic levels have less energy than the lower ones.
The trophic levels of food chainThe food chain is defined as a feeding pathway that consists of similar organisms that are placed in the same trophic levels.
Trophic levels in a food chain are those levels that is occupied by a group of organisms that have a similar feeding mode.
The plants which are the producers are at the lower trophic level while the carnivores are at the higher trophic levels.
The carnivores eats meat from other animals but not plant or plant products which obtain direct energy from sunlight.
Therefore, It is more difficult for top carnivores to obtain sufficient energy resources than it is for animals lower on the food chain because the higher trophic levels have less energy than the lower ones.

A cross between a pink 4 o'clock plant and a pink 4 o'clock plant results in a
ratio of 1 Red: 2 Pink: 1 White. What type of inheritance pattern is represented
here?
Answer and Explanation:
Red four o clocks are h/o/m/o/z/y/g/o/u/s RR.
White four o clocks are h/o/m/o/z/y/g/o/u/s WW.
R is not dominant to W and W is not dominant to R. This means that there is an incomplete dominance (or semi-dominance), where the phenotypes will mix and the Dominant alleles doesn't mask the affect of the Recessive alleles.
Pink four o clocks are h/e/t/e/r/o/z/y/g/o/u/s RW.
#teamtrees #PAW (Plant And Water)
Answer: Incomplete dominance
Explanation:
Pink is the third phenotype. The red allele and the white allele do not mask each other. The third phenotype is between the two traits.

A researcher is curious if Bt resistant bollworms are susceptible to an insecticide called DDT. Bollworms susceptible to Bt have genotype RR or Rr, whereas those resistant to Bt have genotype rr. Bollworms susceptible to DDT have genotype tt, whereas bollworms resistant to DDT have genotypes Tt or TT. In an effort to better understand how these two genes are inherited, the researcher crosses an RR tt bollworm with an rr TT bollworm to produce the F1 generation. Then, the researcher crosses the F1 generation to produce an F2 generation. What proportion of the F2 generation is resistant to both Bt and DDT
Answer:
The correct answer is - 3/16 or 18.75% portion will be resistant to both Bt and DDT.
Explanation:
It is given that bollworms that are susceptible to Bt are represented by either RR or Rr and resistance one are shown by rr genotype and bollworms that are resistant to DDT are represent TT or Tt genotype and susceptible to DDT have tt genotype.
Cross: RR tt with rr TT
Gametes: Rt and rT
