Answer:

Explanation:

The F[tex]_1[/tex] and F[tex]_2[/tex] Generations are drawn in Punnett squares below. Please excuse the messy drawings.

Ratios:

F1 Generation:

RW - Red and White Cross - 4/4 = 100%

F2 Generation:

RR - Red only - 1/4 = 25%

RW - Red and White Cross - 2/4 = 50%

WW - White only - 1/4 = 25%

Tagging and wildlife tracking. Thus, option "C" is correct.

Wildlife tracking is a process employed by biologists and scientific researchers including conversational agencies to remotely the movements and migratory patterns of free-ranging wild animals using GPS and other sensors.

The tracking and monitoring of these endangered species is vital because it helps in the conservation process. Through the monitoring of wildlife, agencies can keep track of animal potters, population demographics and habitat utilization.

Thus, option "C" is correct.

The hydrogen ion concentration of the following pH samples is as follows:

The pH is a measure of the concentration of the hydrogen ion (H+) in water. This means that a relationship exists between H+ and pH of a solution.

The mathematical relationship between pH and H+ concentration ([H+]) is as follows:

pH = –log [H+]

Speciation is the process in which new species are created through evolution. I might be wrong though.

the evolutionary process through which new species emerge

Answer:

four daughter cells

Explanation:

The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell. Meiosis has both similarities to and differences from mitosis, which is a cell division process in which a parent cell produces two identical daughter cells.

Fight or flight

The amygdala activates this fight-or-flight response without any initiative from you. When that part of your brain senses danger, it signals your brain to pump stress hormones, preparing your body to either fight for survival or to flee to safety.

A ligamentous connection such as an antebrachial interosseous membrane is called a syndesmosis.

A fibrous joint called the syndesmosis is held together by ligaments. It is situated between the distal fibula, or outside leg bone, and the tibia, or shinbone, close to the ankle joint. It is also known as the distal tibiofibular syndesmosis for this reason.

syndesmosis is made up of a number of ligaments. The top three are:

The syndesmosis ligament supports and stabilizes your ankle by acting as a shock absorber. Its primary function is to keep the tibia and fibula in line and from extending outward too much.

This is because my parents were heterozygous for the color of the beans. The color of the plant beans is the case of simple Mendelian laws, as there are only two choices for the color of the beans.

Mendel's laws refer to a specific pattern of how a trait is passed from parent to offspring. These common patterns were established by the Austrian monk Gregor Mendel, who conducted thousands of experiments on bean plants in the 19th century.

If the two versions are different, the genotype of the gene is heterozygous. For example, a heterozygous hair color means that there is one red hair allele and one brown hair allele. The relationship between the two alleles affects which trait is expressed.

The value that can be withdrawn from case 1 is the activeness of the government that takes some crucial steps to maintain the biodiversity of the forests. The value that can be withdrawn from case 2 is the sincerity of native people towards nature who make a lake a sacred grove and start worshipping it in order to maintain the biodiversity of that lake.

Biodiversity may be defined as the sum total of all the living entities living in a particular area at a given time.

For maintaining the biodiversity of the forest as well as a lake, it is required not to deteriorate the natural ecosystem of those regions by human activities like over grazing, forest fires, over harvesting, industrialization, etc.

If the forest has not been declared a biodiversity hotspot, the time will not be far to announce that a forest becomes a bare area, where no species live, survive, and reproduce naturally.

Therefore, it is well described above.

“Biomagnification or biological magnification is the process of accumulation of certain chemicals in living organisms to a concentration higher than that occurring in the inorganic, non-living environment.”

Human beings occupies the top place of most trophic level and we know that concentration of harmful chemicals increase as we go above the trophic level. Therefore human beings are most adversely affected by biological magnification.

Humans may also be affected due to the consumption of fish and shellfish.

Answer:

A

Explanation:

a - What happens when organisms don't decompose? If there were no decomposers, wastes and the remains of dead organisms would pile up and the nutrients within the waste and dead organisms would not be released back into the ecosystem. Producers would not have enough nutrients.

b - What happens when a catastrophic mass extinction occurs? A mass extinction event is when species vanish much faster than they are replaced. This is usually defined as about 75% of the world's species being lost in a 'short' amount of geological time - less than 2.8 million years

c - What does the shifting of tectonic plates cause? At the “seams” where tectonic plates come in contact, the crustal rocks may grind violently against each other, causing earthquakes and volcano eruptions. The relatively fast movement of the tectonic plates under California explains the frequent earthquakes that occur there.

d - Volcanic ash doesn't actually do that.

Now, how do fossil fuels form? After millions of years underground, the compounds that make up plankton and plants turn into fossil fuels. Fossil fuels are formed when the organic matter that has been buried deep within the earth is subject to heat and pressure over millions of years.
