The “great dying,” which saw 96% of all species extinct, was partially caused by(1 point)
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.

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

Answer:
Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.

g There are three alleles at a gene determining eye color in a population of wild cats, the B allele (brown eyes) is dominant to both the G allele (green eyes) and the Y allele (yellow eyes). The G allele is dominant to the Y allele. In a population of 1000, there are 100 yellow-eyed cats, 400 green-eyed cats, and 500 brown-eyed cats. What is the expected frequency of the Y allele
Answer:

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
F1 cross:
RT
rT RrTt ( susceptible Bt and resistant DDT)
F1 Cross with F1
Gametes: RT, Rt, rT and rt

Non vascular plants are quite commin in the forests along the coast of Norther California but are relatively rare in the ecosystems around Davis in the Central Valley. What aspects of the life cycle of these plants make it difficult for them to reproduce on our area
Answer:
The Central Valley of northern California is a region where there is little water supply, while nonvascular plants cannot efficiently store water and they have primitive traits that are dependent on water for reproduction.
Explanation:
The Central Valley of northern California is characterized to have little natural precipitation/snowmelt during the dry summer months. In addition, California's climate also has extended periods of drought. On the other hand, non-vascular plants such as mosses and liverworts, are a type of plant that lacks vascular tissues (xylem and phloem), and they also lack true roots, stems, or leaves. These plants cannot efficiently absorb and store water (which fundamental for survival), and thereby the success of these plants in establishing and reproducing in the ecosystems of the Central Valley is limited to their physiological tolerance to desiccation. Moreover, non-vascular plants may also exhibit primitive traits related to their reproductive cycle (e.g., a flagellated sperm) that are dependent on water for reproduction.
For the human population to increase in size, what must exceed the death rate?

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.
Which one of these does not add CO2 to the atmosphere?
Answer:
Planting trees, CARBON CYCLE, and cooking with gas do not add Carbon dioxide to the atmosphere.
Explanation:
The atmosphere naturally breathes or decomposes carbon dioxide rocks, whereas forest fire takes place and volcanoes erupt.
The atmosphere is naturally decomposed. Human activities like fossil fuel and forest burning, and cement production, also add carbon dioxide to the atmosphere.

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.
