Help please . when and where would you expect to find the highest rate of primary productivity?
o a. in the temperate regions during the summer months
o b. in the polar regions during the summer months
c. in the polar regions during the fall
o d. in the tropics during the fall
Expected to find the highest rate of primary productivity in the tropics during autumn
In which ecosystems is primary productivity highest?The more sunlight the system receives, the greater the productivity. Thus, in tropical regions — where there is more sunlight and temperatures are higher throughout the year — productivity is higher than in places with a
temperatecold or polar climate.With this information, we can conclude that Expected to find the highest rate of primary productivity in the tropics during autumn

A. pharynx
B. larynx
C. trachea
D. Esophagus
The cavity which separate or in between the nose and the mouth is the nasal cavity.
The nose and the mouth meet at a junction called the pharnx; option A
What is nasal cavity?The nasal cavity refers to a large, air-filled space above and behind the nose in the middle of the face. It is the cavity which divides the nose and mouth.
However, the nasal septum divides the cavity into two cavities .
The larynx is the passageway for air between the pharynx above and the trachea below.The pharynx carries air, food and fluid down from the nose and mouth.So therefore, the cavity which separate or in between the nose and the mouth is the nasal cavity.

Selective breeding is a technique to obtain offspring with desired traits, characteristics of cattle include meat and height, whereas wheat is obtained by crossing high yield plants.
What is Selective breeding?Selective breeding is a human technique used to obtain descendence (either plants or animals) from a given genetic cross.
This technique (selective breeding) is used in agriculture to obtain wheat with higher grain yields.
Two characteristics of cattle that have been human-driven selected include meat and average size (height).
It is possible to obtain wheat with desired features by crossing plants having desired genes (it is an autogamous plant).
The characteristics of the chickens (Kendo and Bibby) are not found here, but it is possible to select desired phenotypes by crossing them and selecting offspring.
In conclusion, selective breeding can be used to obtain offspring from a given genetic cross expressing desired traits.

From the illustration, it can be said that the age of the rock layer is the same in the four locations of index fossil 1.
Age of fossilIt is a measure of how long a material has been fossilized.
Thus, if a rock layer contains a fossil and another similar rock layer does not have the fossil, one can conclude that the ages of the rock layers are different.
Only index fossil 1 is found in all the four locations as shown in the image. Hence, one can as well infer that the rock layers in all these four locations are of the same age.

How does sea level change when Earth's global temperature is lower?
A. Glaciers grow bigger, causing sea level to fall.
B. Glaciers grow smaller, causing sea level to fall.
C. Glaciers grow smaller, causing sea level to rise.
D. Glaciers grow bigger, causing sea level to rise.
Glaciers grow smaller, causing sea level to rise when Earth's global temperature is lower. Thus, the correct option is C.
Sea level lowers during cold climate periods, known as glacial epochs or ice ages, due to a shift in the global hydrologic cycle, in which water evaporates from the oceans and is stored on the continents as massive ice sheets, extended ice caps, ice fields, and mountain glaciers. At the last glacial maximum, some 20,000 years ago, global sea level was about 125 meters lower than it is today.
What is interglacial epochs?Because the melting North American, Eurasian, South American, Greenland, and Antarctic ice sheets returned their stored water to the world's oceans as the climate warmed, sea level rose. Sea level is at its highest during the warmest eras, known as interglacial epochs.
We are currently living in the most recent interglacial, which began around 10,000 years ago and is referred to by geologists as the Holocene Epoch. Sea levels were about 3 to 20 meters higher than they are now during several previous interglacials.

Some organisms have genes that improve their ability to survive and reproduce. If the gene also help their offspring survive and reproduce, then frequency in gene in population get increase.
What is gene?A gene is the basic physical and functional unit of heredity. Genes are made up of DNA and each chromosome contains many genes.
Throughout the individual lives, their genomes interact with their environments to cause variations in traits which help an organism to adapt better to the environment. These changes which help the organism's survival are selected and passed on to next generation. The genes help in increasing the fitness of the organism and thus the gene frequency changes. . The frequency of these gene increases as they are selected favourably.

Human epithelium contains a layer of cube-shaped cells. If the length, height,
and width of such a cell is 1 micrometer (um), what is the cell's ratio of
surface area to volume?
Answer:
The ratio is 6 to 1
Explanation:
1. a 6 sided cube of 1 mM has a volume of L * W* H (1*1*1=1) 1 mM.
2. a 6 sided cube has a surface area of one face surface area times 6 or (L * W) * 6 = 1mM * 1 mM * 6 = 6
so the ratio of surface to volume is 6/1.

The part of the water cycle that caused water droplets to form on the side of the plastic bag would be condensation.
What is condensation?It is a process whereby water vapor in the atmosphere condenses or turns back into liquid.
Condensation is as opposed to evaporation. The latter is a process whereby liquid water turns into vapor water. In other words, evaporation and condensation are words and opposites.

In a certain population of rabbits, the allele for brown fur
is dominant over the allele for white fur. If 10 out of 100
rabbits have white fur, what is the allele frequency for
the recessive allele?
The Hardy-Weinberg equation is:
[homozygous dominant]2 + 2[heterozygous] +
[homozygous recessive]- = 1
• A. 0.32
• B. 0.10
• C. 0.95
• D. 0.90
SUBMIT
The allele frequency for the recessive allele is B. 0.10. Thus, option "B" is correct.
How, explain your answer?The Hardy-Weinburg equation is p + q = 1, or p^2 + 2pq + q^2 = 1, where p is dominant and q is recessive.
If 10 out of 100 rabbits have white fur, 10% of the rabbits have white fur. Therefore, 90% of the rabbits have brown fur, which can be substituted into the first equation to becoming 0.9 + 0.1 = 1. Now that we know what p and q equal, we can solve the rest of the equation.
0.9^2 = 0.81
0.9 * 0.1 * 2 = 0.18
0.1^2 = 0.01
Therefore, the allele frequency of the recessive allele is 0.1.
