Several scientists travel to a remote coast to study the biodiversity of the area. How could the scientists calculate the species richness of the ecosystem?
A. counting the total number of different species
B. calculating the number of organisms in each trophic level
C. counting the total number of individual organisms
D. calculating the number of producers in the area
Answers
Answer:
A. counting the total number of different species
Explanation:
The only way to calculate the species richness in the ecosystem is counting the total number of different species. This is basically what species richness is, therefore it would be the best way to calculate it. Species Richness does not require that the scientists take into account the population of each species instead, each unique species found is counted as 1 towards the calculation of species richness.

What is Solar System?The solar system is made up of a number of planets and their moons that revolve around a main star.
Comet: A heavenly body with an ice nucleus and a stream of gas and dust
Under geophysical definitions of the term, the Moon qualifies as a satellite planet because it is a planetary-mass object that developed into a differentiated rocky body. There isn't much of an atmosphere, hydrosphere, or magnetic field there.
Therefore, the sun is it, but it goes beyond that, it also includes everything that revolves around the sun, eight planets are known to orbit our sun.

During passive transport, the molecules move from: *
A. Low to High Concentration (comfy --> crowded)
B. High to Low Concentration (crowded --> comfy)
Answers
Answer:
B. High to Low Concentration (crowded --> comfy)
Explanation:
Passive transport is defined as the transport of molecules from high concentration to low Concentration across cell membranes without using energy. Passive transport is based on the second law of thermodynamics. An example of passive transport is diffusion.
Hence, the correct answer is "B. High to Low Concentration (crowded --> comfy)".
Answer:
B. High to Low Concentration (crowded --> comfy)
Explanation:
In passive transport, substances simply move from an area of higher concentration to an area of lower concentration, which does not require the input of energy. Concentration gradient, size of the particles that are diffusing, and temperature of the system affect the rate of diffusion.

Zebrafish (Danio rerio) is an important model organism in the field of genetics. One of the first mutant genes to be studied in this species was golden. The mutant allele was discovered in a pigmentation mutant purchased from a pet store, which changed the color of the fish from the wild-type silver-white coloration to a pale golden color. Calculate the percent likelihood of golden offspring from a cross between a heterozygous wild-type male fish to a golden female fish a 0% b 50% c 25% d 100%
Answers
Answer:
b
Explanation:
Let the wild type trait, the silver-white, be represented by A allele and the mutant trait, the golden color, be represented by a allele.
Heterozygous wild-type male fish would be Aa
Golden female fish would be aa
Aa x aa
Aa Aa aa aa
2/4 Aa = silver-white
2/4 aa = golden color
Hence, the percent likelihood of golden offspring is 2/4 or 50%.
The correct option is b.

Deforestation is the process of cutting down trees by man, which eventually lead to the the sparseness of trees in otherwise forested areas. The reasons for cutting trees by man may include: habitation by man, clearing the land for agriculture or grazing, or using the timber for fuel, construction or manufacturing as well as mining of minerals.
Deforestation leads to many adverse effects on both man and his environment. These adverse effects include:
Loss of biodiversity in the forests which may lead to extinction of species.; when forest areas are cleared, plants and animals who live in these forests lose their homes and some may eventually die off due to inability to survive in other habitats
Increase in temperature of the earth: Trees serves to cool the earth by removing some gases which cause heating of the earth from the earth. Such gases include carbon dioxide. When these tree are removed, these gases accumulate in the atmosphere leading to increase in earth's temperature.
Also, since tree absorb some gases while releasing others into the atmosphere, when these trees are cut, there would be an imbalance of these atmospheric gases.

b. It is a new field of ocean science.
c. The ocean releases one quarter of the carbon dioxide in the atmosphere.
d. All of the above
Answers
Answer:
d. All of the above
Explanation:
All of the given choices are reasons to study the ocean carbon cycle. The ocean occupies about 70% of the earth surface area and it plays important roles in carbon cycling.
The ocean acts as reservoir for carbon in many different ways especially due to the dissolution of this gas in it. It also releases a significant amount of carbon dioxide to the atmosphere due to the plethora of life within it. The field is also relatively new and more works must be done to understand this cycle.Answer:

Explanation:
is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. Most of the time, the photosynthetic process uses water and releases the oxygen that we absolutely must have to stay alive. Oh yes, we need the food as well!

Explanation:
1. If a heterozygous individual (Aa) were crossed with another heterozygous individual (Aa), what
is the chance that their offspring would have a heterozygous genotype?
A 0%
B. 50%
C. 75%
D. 100%
Answers
Answer:
B
Explanation:
The chance that their offspring would have a heterozygous genotype is 50%. The correct option is B.
What is a heterozygous individual?In terms of genetics, being heterozygous means having inherited various alleles (variations) of a certain genomic marker from each biological parent. A person who has two copies of a genetic marker is said to be heterozygous for that marker.
When two heterozygous people are crossed, the offspring's genotype and phenotypic ratios will be predictable.
A person who is heterozygous for a gene has two distinct alleles. In this scenario, there would be a 50% probability that the person would inherit one allele and a 50% chance that they would receive the other allele.
There is a 1/4 chance of having children that are heterozygous for both genes.
Therefore, the correct option is B. 50%.
