Answers

Answer 1

Answer:

The main difference between chromatin and chromosome is that chromatin consists of the unravelled condensed structure of DNA for the purpose of packaging into the nucleus whereas chromosome consists of the highest condensed structure of the DNA doublehelix for the proper separation of the genetic material between

Why does the earth have different layers?

Answers

Answer:

The earth has different layers because as it formed, the lighter parts (like continental crust) floated to the surface, and the really heavy parts (like iron and nickel in the core) sank to the middle. It is just like when you mix oil and water: the oil will float to the surface because it is lighter (or less dense) than the water.

Flower color in the garden pea is due to two interacting genes, A and B. If either gene is recessive (aaB_, A_bb, or aabb) then the phenotype is white. A dominant allele must be present at both genes for flower color to be purple. After a testcross of an individual with a genotype of AaBb, what proportion of the progeny will have purple flowers

Answers

Answer:

4/16 = 1/4 = 25% of the progeny is expected to be purple (AaBb)

Explain how ocean temperatures affect the climate of coastal cities.

Answers

Answer:

Explanation: Warm ocean currents heat the air above the water and carry the warm air to the land, increasing the temperature of the coastal region. The same is true for cold ocean currents, except that they carry cooler air to the land and lower the temperatures of the coastal region.

Answer:

Warm and cold ocean currents can influence coastal climate, but only when local winds come in from the sea. Warm winds heat the air over the ocean, causing temperatures to rise over land. Cold currents will cool the air and add cooler temperatures to the land.

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.

Answers

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.

What is the difference between genetic drift and natural selection?

Genetic drift is the random increase or decrease of certain genes in a population; natural
selection is not random.

Genetic drift is the selection of random traits in a population; natural selection is the
selection of specific traits.

Genetic drift is the frequency of genes in a population; natural selectic is the frequency
of adaptations in a population.

Genetic drift is the change in a population's genes over time; natural selection is the
evolution of a population over time.

Answers

A) Genetic drift is the random increase or decrease of genes in a population. Natural selection is not random.

Genetic drift is the change in the frequencies of alleles in a population due to chance events (random survival). Genetic drift exhibits strong effects in small populations and plays a smaller role the larger the population gets. Natural selection is the non-random change in the frequency of alleles in a population over time, because the change in frequency of the alleles is dictated by the different relative fitnesses that different alleles confer.

Why is it more difficult for top carnivores to obtain sufficient energy resources than it is for animals lower on the food chain?

Answers

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 chain

The 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.
