Question 1 options:
fungi
air
soil
light
salinity
Answer:
light
Explanation:
An abiotic factor is a non-living component in the environment. This can be either a chemical or physical presence. Abiotic factors fall into three basic categories: climatic, edaphic and social. Climatic factors include humidity, sunlight and factors involving the climate. Edaphic refers to soil conditions, so edaphic abiotic factors include soil and geography of the land. Social factors include how the land is being used and water resources in the area. Five common abiotic factors are atmosphere, chemical elements, sunlight/temperature, wind and water.
Temperature and Light

•••
Temperature of the air and water affect animals, plants and humans in ecosystems. A rise in temperature has the potential to change the way a living thing develops, because it changes the metabolic rate of the organism. All living organisms have a tolerance level for temperature range. For example, a human being would die if he stood out in minus 50 degree temperatures for any length of time. Light exposure often affects the temperature. Areas with direct sunlight are warmer

Explanation:
in an ecosystem, lion eat gazelles and gazelle eat wild grasses. What happen if the population of lion is decline?
Answer: gazelle populaton would increase, and wild grasses would decrease
Explanation: becuase lions are decreasing, less and less gazelles are being eating, giving room for more gazelles to be born, increasing their population, and beause there are more gazelles, they are eating more and more grass, deacreasing the grass.

Two morphologically identical Drosophila populations live in Lower Nahal Oren, Mount Carmel, Israel. There are two slopes of a valley that face each other and drosophila live on both slopes (they share a common ancestor). The environment is very different even though they are very close. In the center of the valley is an area in which flies from each side have an opportunity to mate. (an aside: This is frowned upon by fly society buy these tiny Montagues and Capulets persist). Evaluate each scenario:
Answer:
There are two possible scenarios
Scenario 1) Genetic flow is acting on these populations
Scenario 2) The original population has recently diverged
Explanation:
Scenario 1:
These two populations of flies should probably express some phenotypic difference due to the environmental condition on each slope. Remember that the phenotype is the product of interaction between the genotype and the environment. However, the difference between populations would exist if they were isolated and separated by an ecological or biological barrier. The barrier would impede genetic flow, and each population would have its particular genetic charge and phenotype.
In the exposed situation, we know that each population inhabits a slope. And that the slopes differ in the environmental conditions. But in the center of the valley, these two populations get to meet and mate. The valley is acting as a corridor between both groups and allows the genetic flow to occur.
Let us remember that gene flow is an evolutive strength only if
there exists migration from one population to the other, and the allelic frequency in one generation is different from the allelic frequency in the next generation.Genetic flow acts homogenizing the allelic frequencies between the two populations, and it might introduce variability into the new one. For genetic flow to be possible, there needs not only the movement of the genes from one population to the other but also the reproduction process on the new population. Hence, it involves an interaction between the dispersion pattern and the reproductive system.
Individuals from both groups get to mate in the valley, leaving fertile offspring. The offspring, carrying genes from both populations, are included in one or the other group, where they will reproduce. In each population, the frequency of genes of the other group increase with time as the flies keep mating. Eventually, genetic flow homogenizes the variability between both populations, making them look similar.
Scenario Two:
It might be an early dispersion event in which the common ancestor of both populations used to inhabit the center of the valley. With time, and as the original population got bigger, dispersion took a significant role. Flies began moving into both slopes. Even though each area has different environmental conditions, there has not been enough time for these animals to adapt morphologically to each side, so they still look identical. Also, as it is an early event, these two new groups are not separated yet, so they have not developed biological barriers between them, and individuals can still mate in the center of the valley.

disturbance destroying an area through the climax of ecological succession
Answer:
hope this helps
secondary succession
Explanation:
Large, low intensity disturbances, such as plowing in conventional agriculture, result in moderate amounts of succession, where species can survive in the soil and quickly recolonize areas after a disturbance. This type of succession is often called secondary succession
adaptation of nerve cell
Answer:
They have a long fiber so they can carry messages up and down the body over long distances. In a stimulated neuron, an electrical nerve impulse passes along the axon. The axon is insulated by a fatty sheath - the fatty sheath increases the speed of the nerve impulses along the neuron.

Three students are arguing about the reason that an apple appears red. Student A claims that it is because an apple absorbs the color red and reflects all other colors away from it. Student B claims that it is because an apple absorbs every other color of light and only reflects red light away from Student C argues that the apple gives off its own rays of red light. With which student do you agree and why?
Answer:
Objects appear different colours because they absorb some colours (wavelengths) and reflected or transmit other colours. ... For example, a red shirt looks red because the dye molecules in the fabric have absorbed the wavelengths of light from the violet/blue end of the spectrum.

explain how the nuclear atom differe from thr unifotm sphere model of the atom
Answer:
The Proton and neutron has the same mass because the number of protons can differ from the number of electrons which give off different charges and can result in a different weight and amount of charge whether its negative or positive
You are a botanist looking at the plant color in a new breed of Snapdragon. The two parent plants are Blue and Green and when you cross them you make F1 plants that are Cyan in color (a light aqua color). The ratio of offspring is as follows: There were 42 plants with Blue flowers (R1), 39 plants with Green flowers (R2) and 86 plants with Cyan flowers. Is the number of your progeny consistent with a single-gene incomplete dominance inheritance pattern
Answer:
Incomplete dominance is the inheritance pattern where the dominant allele did not mask the recessive allele completely and form a mix of both alleles. Here the inheritance is the incomplete inheritance. The ratio of F2 generation is 1:2:1.
Given:
R1R1 = 42
R2R2 = 39
R1R2 = 86
Total R1 alleles = 2*42+86 = 170
Total R2 alleles = 2*39+86 = 164
Total alleles = 334
Frequency of allele R1 = 170/334 = 0.51
Frequency of allele R2 = 164 / 334 = 0.49
Expected number of each phenotype:
Total population = 167
Blue = R1R1 = 0.51 * 0.51 * 167 = 43.44
Green = R2R2 = 0.49 * 0.49 * 167 = 40.10
Cyan = 2*R1*R2 = 2*0.51*0.49*167 = 83.46
Phenotype Observed(O) Expected (E) O-E (O-E)2 (O-E)2/E
Blue 42 43.44 -1.44 2.0736 0.0477
cyan 86 83.46 2.54 6.4516 0.0773
green 39 40.1 -1.1 1.2100 0.0302
Total 167 167 0.1552
Chi-square value = 0.155
Degrees of freedom = no. of phenotypes – 1
Df = 3-1 = 2
Critical value = 5.99
Chi-square value of 0.155 is less than the critical value of 5.99. So we accept the null hypothesis.

Explanation:
During mammalian embryogenesis, the first differentiation event that occurs leads to a polarization of the outer cells of the 16-cell morula. This outer layer of cells forms the trophectoderm and the inner, apolar clump of cells become the inner cell mass. The inner cell mass will give rise to:
Answer:
the entire embryo
Explanation:
The trophectoderm refers to the polarized single cell layer that forms the wall of the blastocyst, thereby forming the first epithelium during embryogenesis. Moreover, the blastocyst is composed of 1-an inner cell mass (ICM) which will form all the tissues of the embryo's body, and 2-an outer layer composed of cells collectively called the trophoblast. The ICM of the blastocyst will form the embryoblast (which subsequently will give rise to the embryo itself) and the fetus, while the trophoblast will form all of the supporting tissues (i.e., amniotic sac, placenta, and umbilical cord). In humans, the blastocyst is the developmental stage of the embryo on day 5 after fertilization.

Explanation:
The two strands of the DNA are antiparallel to each other such that at the end of the DNA one strand will be 3' paired with a 5' end.
a. True
b. False
Answer:
True
Explanation:
Two strands of DNA are antiparallel to each other because they appear in opposite direction and are mirror image and they are read in 5' - 3' direction which also refers to the orientation of nucleotides of a single strand of DNA and the reading would start from the free phosphate and it will end at the hydroxyl group
